Safety Precautions

Read this manual and follow all instructions prior toinstalling or operating the compressor.

Listed below are some, but not all, safety precautions thatmust be observed with compressors and compressed airsystems.

WARNING!Failure to follow any of these precautions mayresult in severe personal injury, death, propertydamage and/or compressor damage.

• Air from this compressor will cause severe injury ordeath if used for breathing or food processing. Airused for these processes must meet OSHA 29 CFR1910.134 or FDA21XDE178.3570 regulations.

• Disconnect and lockout all power supplies to thecompressor plus any remote controllers prior toservicing the unit.

• Never assume it is safe to work on the compressorbecause it is not operating. Many installations haveautomatic start/stop controls and the compressor maystart at any time.

• This compressor is designed for use in thecompression of normal atmospheric air only. Noother gases, vapors or fumes should be exposed tothe compressor intake, nor processed through thecompressor.

• Relieve all pressure internal to the compressor priorto servicing. Do not depend on check valves to holdsystem pressure.

• A properly sized pressure relief valve must beinstalled in the discharge piping ahead (upstream) ofany shutoff valve (block valve), heat exchanger,orifice or any potential blockage point. Failure toinstall a pressure relief valve could result in therupturing or explosion of some compressorcomponent.

• Do not change the pressure setting of the pressurerelief valve, restrict the function of the pressure reliefvalve, or replace the pressure relief valve with a plug.Over pressurization of system or compressorcomponents can occur, resulting in death, severepersonal injury or property damage.

• Never use plastic pipe, rubber hose, or solderedjoints in any part of the compressed air system.Failure to ensure system compatibility withcompressor piping is dangerous.

• Never use a flammable or toxic solvent for cleaningthe air filter or any parts.

• Do not remove any guards or cabinet panels orattempt to service any compressor part while thecompressor is operating.

• Do not operate the compressor at pressures in excessof its rating.

• Observe control panel displays daily to ensurecompressor is operating properly.

• Follow all maintenance procedures and check allsafety devices on schedule.

• Never disconnect or tamper with the high airtemperature (HAT) sensors.

• Compressed air is dangerous, do not play with it.

• Use the correct fluid at all times.

• Do not rely on the discharge air line check valve.

• Do not override any safety or shutdown devices.

• Keep doors closed during operation. The noise levelinside cabinet exceeds 100 decibels (dBA) and theoperating temperature of some components issufficient to burn the skin.

General Description

The QSB/T™ line of rotary screw compressors covers ahorsepower range of 15 to 50. These belt drivencompressors have standard full load pressure ratings of100, 125 and 150 PSIG. The large, 127mm rotors allowQuincy to operate these compressors at lower speeds thancompetitive makes. While base mounting is standard, 120and 200 gallon tank mounting is available.

The compressor is a single stage, positive displacement,fluid-flooded rotary screw type unit, consisting of twoprecision-machined rotors. The drive rotor is driventhrough a v-belt arrangement.

All components are attached to a heavy-duty steel frame.Controls and indicators are arranged on a control panel.Acoustical cabinets are available to reduce sound levels.

The Compression Cycle

The compression cycle of a rotary screw compressor is acontinuous process from intake to discharge with noreciprocating mechanisms starting and stopping as foundin reciprocating compressors. The compressor consists oftwo rotors in constant mesh, housed in a cylinder with twoparallel adjoining bores. The male drive rotor has fourlobes that mesh with six flutes in the female rotor. Allparts are machined to exacting tolerances.

As the rotors rotate, (male-clockwise as viewed from thepower input end) air is drawn into the cylinder throughthe inlet port located at the power input end. A volume ofair is trapped as the rotor lobes pass the inlet cut offpoints in the cylinders. Compression occurs as the malerotor rolls into the female flute, progressively reducingthe space thereby raising the pressure. Compressioncontinues until the lobe and flute pass the discharge port.The compressed air is then discharged into the air/fluidreservoir. There are four complete compression cyclesfor each complete rotation of the male rotor.

Air Flow

When the compressor is operating, a partial vacuum isproduced at the compressor inlet. Air entering via the airfilter flows through the inlet valve into the rotor housingwhere it is compressed, then discharged into the air/fluidreservoir. Compressed air passes through the completesystem, then through a minimum pressure check valve tothe service connection.

Cooling System

Fluid Coolers

Fluid coolers may use either air or water as a coolingmedium. The following descriptions point out the majordifferences between the two types of coolers.

Air-cooled Fluid Coolers

The air-cooled fluid cooler and aftercooler are finnedaluminum tube, one piece design. Ambient air is forcedthrough the fins by a motor driven fan, cooling the fluidand air in the tubes. To maintain proper compressoroperation, the ambient air temperature should not exceedthe temperatures listed in Appendix B - Technical Data.The cooler fins must be kept clean at all times. Fluidleaving the receiver passes through a thermal mixingvalve before traveling on to the cooler. The purpose ofthe thermal valve is to maintain a minimum fluiddischarge temperature at the compressor of approximately180°F.

Water-cooled Fluid Coolers

Water-cooled fluid coolers are of the shell and tubedesign. Fluid passes through the shell transferring its heatto the water flowing through the tubes. Fluid leaving thecooler does not pass through a thermal mixing valve as inan air-cooled unit, but goes directly to the fluid filter andthe compressor. Fluid discharge temperature at thecompressor is maintained by a water temperatureregulating valve located in the discharge water line. Thewater temperature regulating valve uses a probe to sensefluid temperature and opens and closes, governing waterflow through the cooler.

Aftercoolers

Aftercoolers reduce the amount of water in the dischargeair. They are used to lower the temperature of thedischarge air thereby condensing water vapor from thecompressed air. This allows most of the contained waterto be trapped and expelled from the unit, reducing waterrelated problems downstream.

Air-cooled aftercoolers are part of the air-cooled fluidcooler. Cooling air from the fan is blown through theaftercooler and the fluid cooler.

Water-cooled aftercoolers are placed in series with thefluid cooler. Incoming water is first directed through theaftercooler and then on to the fluid cooler.

Moisture Separator

A combination moisture separator and water trap isprovided for collecting and expelling water to thecustomer’s drain.



Capacity Control System

As the motor starts driving the compressor rotors, air isdrawn in, compressed and discharged into the air/fluidreservoir. When the air pressure in the air/fluid reservoirexceeds the set point of the pilot valve (normally 100PSIG), the valve opens and passes a controlled volume ofair to the inlet valve air cylinder.

NOTICE!Other pressures are available optionally.

The air forces a piston to move within the cylinder,closing the inlet valve. The compressor will continue torun, matching air demand with air delivery by constantlyadjusting the position of the inlet valve. The inlet valveregulates compressor capacity between 100% and nearly0% of rated delivery.

When maximum pressure (typically 10 PSIG abovenormal full load pressure) has been obtained in the airsystem, complete compressor unloading occurs. Thepressure switch located in the control panel sends a signalto the control and the solenoid valve opens, venting theresidual pressure from the blowdown valve. At the sametime, control air from the reservoir check valve is directedthrough the solenoid to the inlet valve air cylinder. Theinlet valve is held in a closed position preventing theintake of air into the compressor and serving as a checkvalve preventing reverse air/fluid flow through the inletvalve and air filter.

Auto Dual (Standard)

The Auto Dual system offers two choices of controllingthe Quincy QSB/T™ Compressor:

With the selector switch in the Continuous Run position,the compressor operates continuously, matching airdemand as the differential pilot valve controls the positionof the inlet valve. When maximum system pressure isreached, the pressure switch opens, venting the air/fluidreservoir and, although the compressor continues to rununloaded, no air is compressed.

When Auto Dual is selected, the compressor will performas above, however, a solid state timer is activated whenthe pressure switch contacts open. This timer isadjustable within a ten (10) minute range. When the timerreaches the end of its delay period, the compressor willautomatically shut down and assume a standby mode.Upon a drop in system air pressure, the pressure switchcontacts close, restarting the compressor automatically.The timer should be set, during unit start-up, for aminimum of six (6) minutes.

During the unloaded/timing mode, if plant pressureshould drop causing the pressure switch contacts to close,the compressor will continue to operate, resetting thetimer and instructing the inlet valve to reopen.



Auto Demand (Optional)

Auto Demand controls accommodate external controlsignals from an optional Quincy Demand-A-Matic®

multiple compressor controller.

With the selector switch in the Local mode, thecompressor will operate as described in the Auto Dualdescription.

In the Remote mode, the compressor’s control panel isbypassed in favor of the Demand-A-Matic® multiplecompressor controller. The compressor will start, buildair, unload and shutdown on time delay as determined bythe Demand-A-Matic® controller. With slightmodifications, a compressor equipped with Auto Dualcontrols may be converted to Auto Demand control.Contact your authorized Quincy Distributor.

Lead/Lag (Optional, two machines only)

This option allows one of two different pressure controlsettings to be chosen for a given machine. If the demandis greater than one unit’s capability, the secondcompressor will automatically turn itself on until theexcess demand has been satisfied. Again, working withthe standard Auto Dual control, the second machinewould time out and turn itself off after the demanddropped.

Load/No Load (Optional)

In the Load/No Load mode, the compressor does notmodulate the inlet valve. The valve is either fully openor it is closed. If system demands include regular periodsof air usage at less than full load, a large compressed airstorage capability is required with this type of control.Without adequate storage, rapid cycling may occur. Thiswill cause wide system pressure fluctuations that mayaffect the performance of equipment using thecompressed air. Load/No Load works with Auto Dualcontrol to turn the compressor off during extendedperiods of no demand.

Electronic Control (Optional)

The QSB/T™ compressor with Electronic Control utilizesa microprocessor to control the compressor. Refer toSection IV for operational instructions.

WARNING!Never assume it is safe to work on a compressorbecause it is not operating. It may be in standbymode and could restart at any time. Follow allsafety instructions in Section V - Maintenance orService Preparation.



Electrical System

Electrical system diagrams are shown in the parts manualsent with the compressor. The appropriate diagram is alsoincluded in the control panel on all Quincy QSB/T™

compressors.

NOTICE!Due to continuous product improvements andupdates, it is suggested that the wiring diagramincluded in the control panel be used whenservicing the electrical control.

Standard drive motors are open drip proof 1800 RPMwith a maximum ambient temperature rating of 104°F.They are not suitable for salt laden, corrosive, dirty, wetor explosive environments.

The QSB/T™ series compressors utilize 460V incomingpower through an across the line magnetic starter. Atransformer in the control panel reduces this voltage to120 VAC for the various controls on the unit. Thesecontrols include the selector switch, pressure switch,timer, high air temperature safety switches, solenoid andthe various indicator lights. Other incoming line voltagesare available as options. The compressor is provided witha NEMA 1 enclosure. Optional panels include NEMA 4.

DANGER!High voltage could cause death or serious injury.Disconnect all power supplies before opening orservicing the electrical enclosure.

Safety Sensors

One high air temperature (HAT) sensor is standard onQSB/T™ units. This sensor is located in the discharge linefrom the compressor to the air/fluid reservoir and protectsthe unit by sensing unusually high temperatures andshutting the unit down. The HAT sensor is set to trip atapproximately 225°F and is nonadjustable.

WARNING!Never remove, bypass or tamper with the HATswitch. Failure to provide this safety feature couldcause death or serious injury and propertydamage. If the compressor is shutting down dueto high discharge temperature, contact a qualifiedservice technician immediately.



Indicators

Receiving

Upon receipt, immediately inspect the compressor for anyvisible damage that may have occurred during shipment.If visible damage is found, the delivering carrier shouldmake a notation on the freight bill and the customershould request a damage report. If the shipment isaccepted and damage is found later, it is classified asconcealed damage. Concealed damage should bereported to the delivering carrier within 15 days ofdelivery. The delivering carrier must prepare a damagereport. Itemized supporting papers are essential to filinga claim.

Read the compressor nameplate to be sure the compressoris the model and size ordered and that optionally ordereditems are included.

Check the reservoir and pressure relief valves to be surethey are adequate for the pressure at which you intend tooperate.

Moving the Unit to the Installation Site

Forklift slots are provided in one side and one end of themain frame. Use of chains and slings should be limited tothe main frame. Do not attempt to lift the unit byattaching to any components. Optional lifting eyes areavailable.

NOTICE!See Appendix A and B for detailed technicalinformation and dimensions.

CAUTION!Improper lifting may result in component, systemdamage or personal injury. Follow good shoppractices and safety procedures when moving theunit.



Location

Locate the compressor on a level surface in a clean, well-lit and well-ventilated area. Allow sufficient space (fourfeet of clearance on all sides and top of the compressor)for safe and proper daily inspection and maintenance.The entire length of the frame base must be supported.Shim where necessary but do not use wood.

WARNING!Under no circumstances should a compressor beinstalled in an area exposed to a toxic, volatile orcorrosive atmosphere, nor should toxic, volatileor corrosive agents be stored near the compressor.

Ambient temperature should not exceed 110°F. Highambient temperatures may result in a high air temperatureshutdown. All models are intended for indoorinstallation, however, it is possible, with certainmodifications, to accommodate some outdoor locations.Cabinet models are water-resistant but not water tight.Sheltering from rain, snow and freezing temperatures ismandatory.

WARNING!Do not operate in temperatures below 32°F orabove the limits outlined in Appendix B - TechnicalData.

Do not locate the unit where the hot exhaust air fromother compressors or heat generating equipment may bedrawn into the unit. Never restrict the flow of exhaust airfrom the fluid cooler or cooling fan. Heated exhaust airmust be exhausted outside to prevent high temperatureconditions in the compressor room. If the room is notproperly ventilated, compressor operating temperatureswill increase and cause a high temperature shutdown.

CAUTION!Clean, fresh air, of sufficient quantity, is requiredfor proper compressor operation.

In high humidity areas, avoid placing the compressor in abasement or other damp locations. Control thecompressor temperatures and monitor compressor fluidfor signs of water contamination. Fluid and filter changesmay need to be increased in high humidity areas.Increased operating temperatures may be required.

CAUTION!Removal or modification of sound insulation couldresult in dangerously high sound levels.

Quincy QSB/T™ compressors are essentially vibrationfree, however, some customers may choose to bolt theunit to the floor to prevent the accidental breakage ofpiping or electrical connections as a result of beingbumped. Use only lag bolts to secure the unit. Do notpull the bolts down tight. Overtightening the lag boltsmay place the frame in a twist or bind causing breakage offluid coolers, piping and reservoirs.

WARNING!Removal or painting over safety labels will resultin uninformed conditions. This could result inpersonal injury or property damage. Warningsigns and labels shall be provided with enoughlight to read, conspicuously located andmaintained for legibility. Do not remove anywarning, caution or instructional materialattached.



Piping Connections

Never join pipes or fittings by soldering. Lead-tin soldershave low strength, a low creep limit, and may, dependingon the alloy, start melting at 360°F. Silver soldering andhard soldering are forms of brazing and should not beconfused with lead-tin soldering. Never use plastic, PVC,ABS pipe or rubber hose in a compressed air system.

Piping Fit-up

Care must be taken to avoid assembling the piping in astrain with the compressor. Piping should line up withouthaving to be sprung or twisted into position. Adequateexpansion loops or bends should be installed to preventundue stress at the compressor resulting from the changesbetween hot and cold conditions. Pipe supports should bemounted independently of the compressor and anchored,as necessary, to limit vibration and prevent expansionstrains. Piping should never be of smaller size than theconnection on the compressor unit.

Relief Valves

Pressure relief valves are sized to protect the system.Never change the pressure setting or tamper with thevalve. Only the relief valve manufacturer or an approvedrepresentative is qualified to make such a change.

DANGER!Relief valves are to protect system integrity inaccordance with ANSI/ASME B19 safetystandards. Failure to provide properly sized reliefvalves will result in death or serious injury.

Relief valves are to be placed ahead of any potentialblockage point that includes, but is not limited to, suchcomponents as shutoff valves, heat exchangers anddischarge silencers. Ideally, the relief valve should bethreaded directly into the pressure point it is sensing, notconnected with tubing or pipe and pointed away from anypersonnel. Always direct discharge from relief valves to asafe area away from personnel.

Relief Valve

Pressure Vessels

Air receiver tanks should be in accordance with ASMEBoiler and Pressure Vessel Code Section VIII.

CAUTION!ASME coded pressure vessels must not bemodified, welded, repaired, reworked or subjectedto operating conditions outside the nameplateratings. Such actions will negate code status,affect insurance status and may cause death,serious injury and property damage.



Electrical

Before installation, the electrical supply should bechecked for adequate wire size and capacity. Duringinstallation, a suitable fused disconnect switch or circuitbreaker should be provided. Any unreasonable voltageunbalance (5%) between the legs must be eliminated andany low voltage corrected to prevent excessive currentdraw. The installation, electric motor, wiring and allelectrical controls must be in accordance with NationalElectric Code, and all state and local codes. A qualifiedelectrician should perform all electrical work. Aircompressors must be grounded in accordance withapplicable codes. See control panel for the proper wiringdiagram.

Quincy would like to emphasize the importance ofproviding adequate grounding for air compressors. Thecommon practice of grounding units to building structuralsteel may not actually provide adequate groundingprotection, as paint and corrosion buildup may exist.

CAUTION!NEMA electrical enclosures and components mustbe appropriate to the area in which they areinstalled.

Pneumatic Circuit Breakers or Velocity Fuses

The Occupational Safety and Health Act, Section1926.303 Paragraph 7 published in Code of FederalRegulations 29 CFR 1920.1 (revised 07/01/1982), states“all hoses exceeding 1/2” inside diameter shall have asafety device at the source of supply or branch line toreduce pressure in case of a hose failure.” Thesepneumatic safety devices are designed to prevent hosesfrom whipping, which could result in a serious or fatalaccident.

Guards

All mechanical action or motion is hazardous in varyingdegrees and needs to be guarded. Guarding shall complywith OSHA Safety and Health Standards 29 CFR1910.219 in OSHA manual 2206 (revised 11/07/1978)and any state or local codes.

WARNING!Cabinet panels and drive guards must be fastenedin place before starting the machine and neverremoved before lock out/tag out of the main powersupply.

Manual Vent and Shutoff Valve

Install a manual valve to vent the compressor and thecompressor discharge line to atmosphere. If the air receiver tankservices a single compressor, the manual valve can be installedin the receiver. When a manual shutoff valve (block valve) isused, a manual valve should be installed upstream from thevalve, and a pressure relief valve installed upstream from themanual vent valve. These valves are to be designed andinstalled to permit maintenance to be performed in a safemanner. Never substitute a check valve for a manual shutoffvalve (block valve) if the purpose is to isolate the compressorfrom a system for servicing.

WARNING!Relieve compressor and system air pressure byopening the appropriate manual relief valve priorto servicing. Failure to relieve all system pressurecould result in death or serious injury andproperty damage.



Water and Sewer Facilities at the Installation Site(Water-cooled models only)

Make sure the water supply is connected and open.Piping supplied by the user should be at least equal to theconnections provided on the compressor. Sewer facilitiesshould be readily accessible to the installation site andmeet all the requirements of local sewer codes, plus thoseof the compressor. Make sure water inlet and dischargeconnections are correct.

NOTICE!The water temperature regulating valve is locatedin the discharge water line.

Clean air is essential for your Quincy QSB/T™

compressor. Always select a source providing thecleanest air possible. When an outside air source is used,keep all piping as short and direct as possible. Usevibration isolators and support all piping correctly.Piping size should be at least as large as the inlet valveopening and increased several sizes for extremely longpiping runs. The piping must be leak free and clean afterfabrication.

Compressor Rotation

Compressor rotation must be checked prior to start-up.Proper rotation is clockwise (as viewed from the power-input end). The power-input end of the compressor ismarked with an arrow noting the proper rotation.Operating the compressor in incorrect rotation will resultin extreme damage to the compressor and warrantycoverage will be voided. To check for proper rotation,jog the starter button, allowing the motor to turn 2 or 3revolutions. Observe the drive element for correctdirection. If incorrect rotation is observed, lock outpower supply, reverse electrical leads L1 and L3 at themotor starter. Recheck for correct rotation.

Fan Rotation

Check the fan rotation at the same time the compressorrotation is being checked. Fan airflow should be outward,that is, pushing the air through the coolers on air-cooledunits or out of the cabinet on water-cooled units withcabinets.

• Prior to Starting• Starting the Compressor• Stopping the Compressor - Normal

Operation• Stopping the Compressor - Emergency• Electronic Control Operation (optional)

Prior to Starting

CAUTION!Provisions should be made to have the instructionmanual readily available to the operator andmaintenance personnel. If, for any reason, anyparts of the manual become illegible or if themanual is lost, have it replaced immediately. Theinstruction manual should be read periodicallyto refresh one’s memory. This may prevent aserious accident.

Before starting the compressor, review Sections II and IIIof this manual. Be certain that all installationrequirements have been met and that the purpose and useof the controls are thoroughly understood. Before placingthe compressor into operation, do the following:

• Remove all loose items and tools from around thecompressor.

• Check fluid level in the air/fluid reservoir. SeeCompressor Fluid Section.

• Check the fan and fan mounting for tightness.

• Manually rotate the compressor through enoughrevolutions to be certain there are no mechanicalinterferences.

• Check all pressure connections for tightness.

• Check to make sure all relief valves are in place.

• Check to make sure all panels and guards are in placeand securely mounted.

• Check fuses, circuit breakers and thermal overloadsfor proper size.

• Close the main power disconnect switch and jog thestarter switch button to check the rotational directionof the compressor.

• Check the fan rotation.

• Water-cooled models - Check inlet and dischargewater piping for proper connections.

• Check for proper belt tension. (Reference V-beltDrive Maintenance - Section VI.)

Starting the Compressor

• Secure all enclosure panels on compressor.

• Open the service valve to the plant air distributionsystem.

• Select the mode of operation and start thecompressor.

• Watch for excessive vibration, unusual noises or air/fluid leaks. If anything unusual develops, stop thecompressor immediately and correct the condition.

• Control settings have been adjusted at the factory;however, they should be checked during start-up andreadjusted, if necessary. Some applications mayrequire a slightly different setting than those providedby the factory. Refer to the Service AdjustmentSection VIII. Never increase air pressure settingsbeyond factory specifications.

• Adjust the water temperature regulating valve tomaintain 180°F discharge air temperature (water-cooled units only).

• Observe compressor operation closely for the firsthour of operation and frequently for the next sevenhours. Stop and correct any noted problems.

• Check for proper belt tension after 24 hours andadjust if necessary. (Reference V-belt DriveMaintenance - Section VI.)



Stopping the Compressor - Normal Operation

Close the service valve to the plant air distributionsystem. Allow the pressure to build within the reservoirand the compressor to fully unload. Turn selector switchto the “OFF” position.

NOTICE!Always close the service valve when thecompressor is not being used to prevent thesystem’s air pressure from leaking back into thecompressor if the check valve leaks or fails.

Stopping the Compressor - Emergency

Press the emergency stop button or cut the power at themain disconnect switch or panel.

Section V - Maintenance or Service Preparation


The following procedure should be followed formaximum safety when preparing for maintenance orservice:

1) Disconnect and lockout the main power switch andhang a sign at the switch of the unit being serviced.

2) Close shutoff valve (block valve) between receiverand plant air system to prevent any backup of airflow into the area to be serviced. NEVER dependupon a check valve to isolate the system.

3) Open the manual vent valve and wait for thepressure in the system to be completely relievedbefore starting service. DO NOT close the manualvent valve at any time while servicing.

4) Shut off water and depressurize system if water-cooled.

WARNING!Never assume the compressor is ready formaintenance or service because it is stopped. Theautomatic dual control may start the compressorat any time. Death or serious injury could result.

Section VI - Servicing

(Water-cooled units Only)• V-belt Drive Maintenance• Belt Replacement• Electronic Control (optional)• Air and Fluid Tubing• O-ring Fittings

Safety

NOTICE!Maintenance should be performed by trained andqualified technicians only.

Safety procedures while servicing the compressor areimportant to both the service personnel and to those whomay be around the compressor and the system it serves.Listed below are some, but not all, procedures that shouldbe followed:

• Wait for the unit to cool before starting service.Temperatures may exceed 180°F when thecompressor is operating.

• Clean up fluid spills immediately to prevent slipping.

• Loosen, but do not remove, flange or componentbolts. Carefully pry apart to be sure there is noresidual pressure before removing bolts.

• Never use a flammable solvent such as gasoline orkerosene for cleaning air filters or compressor parts.

• Safety solvents are available and should be used inaccordance with their instructions.

CAUTION!Unusual noise or vibration indicates a problem.Do not operate the compressor until the sourcehas been identified and corrected.

Water Removal

Water vapor may condense in the reservoir and must beremoved. The frequency with which water must beremoved is determined by the ambient air conditions.During hot and humid conditions, water should be drainedoff the bottom of the reservoir daily. In cold and dryconditions, water may only need to be drained weekly. Todrain water from the reservoir, turn the compressor offand let sit for at least 5 minutes. Then open the drainvalve. Water is heavier than the compressor fluid and willcollect at the bottom of the reservoir. When the drain isfirst opened some compressor fluid may come out beforethe water starts to flow. Close the valve when the waterflow changes to compressor fluid. Make certain that thereis no pressure in the reservoir before opening the drainvalve. Water content in the compressor fluid in excess of200 PPM could cause bearing damage and airend failure.



Air/Fluid Separator Elements

Continuity Testing of Separator Elements

NOTICE!Electrical continuity between all separatorelement metal surfaces must be checked prior toreplacing any separator element. Do not installif continuity is not present. Return the separatorelement to your Quincy Distributor forreplacement.

Prior to installation, test the separator element as follows:

1) Locate a continuity test light or a volt-ohm-meter(v-o-m) capable of reading 20 ohms.

2) Assure that battery has proper charge. Touch theprobe leads together to assure the light works or tozero calibrate the meter.

3) Contact the grounding spring clip on the separatorelement gasket with the ground probe of the testindicator.

4) Touch the top cap of the separator element with theother probe. The indicator light should illuminateon the test or the v-o-m test must read no more than20 ohms.

5) Touch the bottom cap of the separator element.The indicator light should illuminate on the test orthe v-o-m test must read no more than 20 ohms.

6) Touch the outside wire mesh. The indicator lightshould illuminate on the test or the v-o-m test mustread no more than 20 ohms.

7) Touch the inside wire mesh ( do not puncture theelement media). The indicator light shouldilluminate on the test or the v-o-m test must read nomore than 20 ohms.

8) If the separator element fails any of the above test ,return it to your Quincy Distributor forreplacement.

9) Make sure the compressor is bonded (wired) to anearth ground to dissipate static electricity.

Air Filter

The standard QSB/T™ air filter is a single stage, dry typeelement attached to the inlet valve. The filter media ispleated and will stop particles of 10 microns in size. Thiselement is replaceable and should not be cleaned. Serviceintervals of the air filter element depends on ambientconditions and should be established by checking regularintervals until a pattern for servicing is found. Dailymaintenance of the filter element is not uncommon indirty conditions. If dirty conditions exist, it is advisable torelocate the intake air to an outside source. Each time thefilter is serviced, inspect the filtered air side of the aircleaner canister and the suction manifold for dirt. If dirt isfound, determine the cause and correct. Always make sureall gaskets, threaded connections, flange connections, andhose connections between the air filter and air compressorare airtight. Dirty filters result in reduced airflow and candistort the element and allow dirt to bypass the filterelement.

NOTICE!Intake filtration equipment supplied from thefactory may not be adequate for extremely dirtyapplications or some forms of dust or vapors. Itis the customer’s responsibility to provideadequate filtration for those conditions.Warranty will be voided if inadequate filtrationcauses a failure.

A heavy-duty air filter is optional on all QSB/T™ models.The heavy-duty air filter is a two stage, dry type element.The first stage is cyclonic. That is, centrifugal airflowspins the larger dirt particles to the outside walls of thefilter canister. In the second stage, air passes through thefilter element with an efficiency of 99.9% as tested bySAE J7266 test code specifications. Removal andreplacement of the element is accomplished byunscrewing the wing nut and exchanging the element.Tighten the wing nut snugly after making certain theelement is seated correctly on its mounting base.

Control Line Filter

An automatic draining control line filter is used. Drainingoccurs only when the compressor is in the unloadedcondition.



Shaft Seal

Compressor shaft seals are wear items that may eventuallyhave to be replaced. Special tools and a completeunderstanding of the installation procedure are requiredfor a successful seal replacement. Ask your Quincydistributor for complete illustrated instructions (availableas a Service Alert) at the time you order the seal andspecial tools, if you decide to replace the seal yourself. Ifyour distributor does not have a copy of theseinstructions, they can be ordered from QuincyCompressor® at no charge.

QSB/T™ compressors incorporate a fluid scavenge systemto complement the use of a triple lip seal assembly. Anycomplaint of shaft seal leakage requires that the scavengesystem be inspected for proper operation prior to thereplacement of the shaft seal. Proper inspection consistsof the following:

• Assure that the scavenge line itself is not plugged.

• Inspect the performance of the scavenge line checkvalve by removing the fitting located at the bottom ofthe motor adapter. Remove the check ball andinspect for wear. If the check valve is stuck open,fluid can backflush from the airend into the sealcavity and appear as a leak. If the check valve isstuck closed the seal cavity will not scavenge.Replace if necessary.

• Remove the four bolts securing the seal adapter to thesuction housing.

• Insert two of the seal adapter retaining bolts into theseal adapter jack holes and turn clockwise (pushingthe seal adapter away from the suction housing).

• After the seal adapter outer o-ring has cleared theseal adapter bore, remove the adapter for inspection.

• Disassemble the seal adapter as follows:

a. With the face of the seal adapter up, insert twosmall, flat screwdrivers under the outer lip ofthe fluid slinger and pop the slinger from theseal adapter bore.

b. Using a brass drift, tap the shaft seal assemblyfrom the seal bore.

c. Inspect both seal lips for excessive wear, lipflaws or damage.

d. Inspect the outer o-ring on the fluid slinger forcuts or nicks.

e. Inspect the outer o-ring on the seal adapter forcuts and nicks.

f. Slide the wear sleeve removal tool over the endof the shaft and allow the jaws of the tool tosnap on the backside of the wear sleeve.Tighten the outer shell of the tool down overthe inner jaws.

g. Using a ratchet and socket, turn the puller jackscrew clockwise in against the end of thecompressor shaft to remove the seal wearsleeve.

CAUTION!Do Not use an impact wrench with this tool.



Preparation for New Seal Installation

• Inspect the compressor shaft for burrs or deepscratches at the wear sleeve area. Using a 100 gritemery cloth, lightly sand horizontally any rust orLoctite™ on the shaft. Using a fine file or emerycloth, deburr the key area of the rotor shaft. Coverthe keyway with masking tape to prevent damage tothe new seal during installation.

• Clean the seal adapter with fast drying solvent.Assure that the scavenge drain in the seal adapter isclean and open. Place the outer face of the sealadapter on a flat, hard surface.

• Remove the new triple lip seal from the package andinspect for damage or imperfections on the seal lips.

• Apply a thin coat of Loctite™ 290 to the outer steelcase of the seal and position the seal in the sealadapter bore.

• Insert the proper seal driver over the seal. Insert theproper wear sleeve driver in the seal driver and tapthe new seal into the bore with a medium sizedhammer.

• Preheat the wear sleeve (in a small oven) to 350°F.Do not preheat in warm oil.

• Apply a thin film of Loctite™ to the inner diameter ofthe wear sleeve and immediately install on thecompressor shaft using the proper wear sleeve driver.Drive the wear sleeve on the shaft until the driverbottoms on the shaft shoulder.

Seal Installation

• Apply a thin coat of compressor fluid to the outerface of the wear sleeve and seal lip.

• Slide the proper seal installation sleeve against thewear sleeve with the taper toward the end of the rotorshaft.

• Install a new o-ring on the seal adapter and lubricatewith compressor fluid.

• Install a new o-ring around the scavenge port (usepetroleum jelly to hold the o-ring on the seal adapterface during installation).

• Carefully slide the seal adapter with the new sealinstalled over the end of the rotor shaft and up againstthe adapter bore.

• Using care not to damage the o-ring, evenly draw theadapter into the bore, install the four retaining boltsand tighten to the specified torque.

• Remove the installation sleeve.

• Apply a thin film of compressor fluid to the o-ringand seal lip of the outer fluid slinger.

• Install the outer slinger over the end of the rotor shaftand push into the scavenge bore using both thumbs.



Differential Pilot Valve

WARNING!Never adjust the pressure higher than the factorysetting. Death or serious injury and compressoror property damage could result.

Open a manual vent valve to allow the compressor toexhaust air to the outside and start the unit. By manualregulation, slowly close the valve, allowing the unit tobuild air pressure to the desired modulation point andhold (100 PSIG standard). Adjust the screw on thebottom of the differential pilot valve so that a slightstream of air can be felt coming from the orifice adjacentto the adjustment screw.

When the air is felt, air is beginning to pass through thepilot valve to the air cylinder on the inlet valve, causingthe valve to modulate toward its closed position, therebyreducing the volume of air being compressed.

To raise the pressure, turn the adjusting screw in(clockwise). To lower the pressure, turn the screw out(counter clockwise). Maximum full load pressure is 100PSIG for standard QSB/T™ units. Minimum full loadpressure with modulation and standard controls is 75PSIG.

Pressure Switch

The pressure switch determines what pressure thecompressor will load and unload. Standard factorysettings are listed in the QSB/T Specifications. If alower setting is desired, adjust the differential pilot valvefirst and set the pressure switch cut-out point to 15 PSIGover the desired full load pressure. The rangeadjustment is made by turning the screw clockwise toincrease the cut-in/cut out pressure. The pressure switchshould unload the compressor by the time it reaches the

20% load point. Raising the pressure without changingthe compressor speed above factory settings will result inhigh amp draw and drive belt failures. Consult your partsbook for proper sheave and belt part numbers.

Water Temperature Regulating Valve(Water-cooled units Only)

The water temperature regulating valve senses fluidtemperature and opens or closes, regulating water flowfrom the unit. It is factory set to maintain 180°Fdischarge temperature. Due to different incoming watertemperatures and/or pressures in various locations, valveadjustment should be checked during start-up tomaintain 180°F discharge temperature. To increase fluidtemperature, decrease water flow by turning theadjustment screw clockwise. To decrease fluidtemperature, increase water flow by turning theadjustment screw counter clockwise. Water pressureshould be 40 psi minimum/100 psi maximum. Watertemperature should be 50°F minimum/90°F maximum.

V-belt Drive Maintenance

QSB/T™ 15 through 30 HP units are equipped with apivoting motor base with a spring tension belt tensioningdevice. QSB/T™ 40 & 50 HP units are equipped with apivoting motor base with a jackbolt for tensioning thebelts. For the best belt life, factory-matched belt setsmust be used with these drive.

The most important factors in the successful operation ofa v-belt drive are proper belt tensioning and sheavealignment. Too little tension can result in slippage,causing rapid belt and sheave wear, too much tensioncan result in excessive stress on belts, bearings, andshafts. Misalignment causes wear and increases theprobability of belt turnover by decreasing stability.



Belt Drive Inspection Procedure

1) Inspect sheave grooves for nicks.

2) Thoroughly inspect the tapered bore of the sheaveand the tapered surface of the bushing. Any paint,dirt, metal chips, fluid or grease must be removed.

3) Position bushing and sheave assemblies and roughalign with a metal straight edge. Mount sheaves asclose to the compressor and/or motor housing aspractical to avoid excessive bearing and shaftloads. Tighten dry capscrews evenly andalternately. Do not use lubricants in thisinstallation. Excessive capscrew tightening cancause sheave and/or bushing breakage. Rotatepulleys to check for sheave runout (wobble) or abent shaft. Hand tighten setscrew over keyway, ifrequired.

NOTICE!After tightening, there should be a 1/8” to 1/4”gap between the mating part hub and the bushingflange.

Correcting Misalignment

To locate the position of maximum misalignment, checkalignment in at least three places after rotating one of thesheaves 120° each time.

Misalignment comes in three varieties: Horizontalangular, vertical angular and parallel. Sheave alignmentshould be within 0.07” per foot of shaft center distance.This is the total of all parallel and angular misalignment.

Horizontal Angular (Shafts in same horizontal plane butnot parallel)

1) To check, use straightedge or string near sheavecenters.

2) To correct, loosen motor mounting bolts and rotatemotor until all four points touch straightedge.

Vertical Angular (Shafts in same vertical plane but notparallel)

1) To check, place straightedge 1/4” from the outsidediameter of both sheaves as shown:

a. Repeat on opposite side of shaft.

b. Straightedge should touch four points asindicated in each position.

2) To correct, loosen sheave so it slides easily on shaftuntil all four points touch straightedge. Tightensheave in position.

3) Loosen motor mounting bolts and shim undermotor feet as needed.

NOTICE!Sheave should be mounted as close to bearing aspossible to reduce overhung load on bearing.Relocate equipment, if necessary.



Parallel (Shafts are parallel; sheaves not in line)

1) To check, use straightedge or string near sheavecenters.

2) To correct, loosen sheave and relocate on shaftuntil all four points touch straightedge. Tightensheave in position.

NOTICE!Never pry the belts into the sheave grooves. Thiscan damage the belt cords and lead to beltturnover, short life or belt breakage.

Tension Specifications

Use belt tension tester (Quincy part # 142645) whenchecking and tensioning the belts. See page 31 forinstructions on proper use of the belt tension tester.

The spring tensioning system used on 15 through 30 HPunits is designed to maintain proper belt tension.However, it is recommended that belt tension be checkedmonthly and confirmed to be within tension requirementslisted in the following table. If not, adjust per instructionson page 32.

*** Belts must be retensioned at or before reaching this tension.



Using the Belt Tension Tester (P/N 142645)

1) Measure the span length (t).

2) Position the large o-ring using either of thefollowing methods:

(a.) On the scale reading “Inches,” set the o-ring toshow a deflection equal to 1/64" per inch ofspan length (t).

(b.) On the scale reading “Inches of Span Length,”set the o-ring to show a deflection equal to theinches of measured span length (t). (Readscales at the bottom edge of o-ring. Set thesmall o-ring at “0” pounds.)

3) Always rotate pulleys a minimum of 2 revolutionsbefore taking belt tension measurements. At centerof span (t) apply force, with belt tension testerperpendicular to the span, large enough to deflectone belt on the drive until the bottom edge of thelarge o-ring is even with the tops of theremaining belts. (A straight edge acrossthe belt tops will assure accuracy ofpositioning.)

4) Find amount of deflection force on theupper scale of the tension tester. Thesliding rubber o-ring slides up the scaleas tool compresses - stays up foraccurate reading of pounds pressure.Read at bottom edge of ring. (Slide theo-ring to back to “0” pounds beforereusing.)

5) Compare deflection force with range offorces listed for unit being tested. Ifless than minimum recommendeddeflection force, tighten belts. If morethan the maximum recommendeddeflection force, drive is too tight.

6) Check tension of each belt on the driveas described above.

7) Check the ride height. All belts in eachset must ride at the same height in thepulley groove within 0.030" total ofeach other.

8) Recheck for pulley misalignment and correct asnecessary. Retension after adjusting.

9) Operate the compressor for a few minutes to seatthe belts in the sheave grooves. Observe theoperation of the drive during start-up and full loadoperation (highest load conditions). A slight bowingof the slack side of the drive indicates adequatetension. Excessive bowing or slippage indicatesinsufficient tension. If the slack side remains tautduring the highest load the drive is too tight.

10) (15-30 HP units) Assure that motor base is levelwhen belts are at initial tension. If motor base islevel, belt tensioning is complete. If not, refer tomotor base instructions in appropriate instructionmanual, level motor base and repeat tensioningprocedure.

The three functions of compressor fluid are:• to lubricate the bearings and rotors

• to remove heat from the air as it is being compressedthus lowering the compressed air dischargetemperature

• to seal the rotor clearances

Fluid Specifications

We recommend that all Quincy rotary screw compressorsbe filled with one of the following synthetic fluids:

QuinSyn PG - Standard fill. (Replaces QuinSyn)QuinSyn XP - Standard fill for high pressure

applications. (Replaces QuinSyn HP68)

QuinSyn Plus- Extended life fluid.QuinSyn F - Food grade applications.QuinSyn IV - 4000 hour alternative fluid.

A fluid tag is attached to each Quincy rotary screwcompressor indicating the type of fluid provided in theinitial fill. All of the above fluids are available from anyauthorized Quincy distributor.

CAUTION!Do not mix different grades or types of fluid. Donot use inferior grades of fluids.

NOTICE!Failure to follow these fluid recommendations willadversely affect your warranty.



Lubrication

Most Quincy Compressors are equipped with a positivedisplacement fluid pump mounted to the compressor anddirectly driven by one of the rotors. Fluid is circulatedthrough the cooler, fluid filter, and into the compressor.In the compressor, fluid is diverted through internalpassages to ensure positive lubrication of the bearings andshaft seal. The remainder of the fluid is injected at thebeginning stage of the compression cycle to sealclearances and to cool and lubricate the rotors. Modelsnot equipped with a fluid pump use pressure differentialto circulate the fluid. Positive pressure maintained in thereservoir forces the fluid throughout the machine.

Each Quincy compressor is filled at the factory with thecorrect amount of one of the synthetic fluid listed in theFluid Specifications. Mineral oil can be requested andused in specific applications. The use of other brands ortypes of fluid may reduce the design life of thecompressor or cause problems with filtration or carryover.Consult the Quincy Service Department before changingbrands of fluid.

Fluid Level

Fluid level is monitored by a sightglass or a dial gaugewhile in operation. Fluid level should be in the “run” areaon the dial gauge or completely fill the sight gauge. DONOT OVERFILL.

Figure 1-1. Fluid Level Sight Gauges

Each unit comes equipped with a fluid level sight gauge,fluid fill opening, and a fluid drain in the reservoir. Thefill plug is drilled to allow some pressure to escape beforethe plug is completely removed. Should you hearpressurized air venting through the hole, immediatelyscrew the plug back into the reservoir. Relieve thepressure in the machine before proceeding.

CAUTION!Hot fluid under pressure could cause death orserious injury. Do not remove the fluid fill plugand attempt to add fluid to the reservoir whilethe compressor is in operation or when the systemis under pressure. Be sure that the compressor’sred mushroom stop button is pushed in and lockedand that the main power disconnect switch is inthe off position and locked out to assure that thecompressor will not start automatically.



Fluid Filter

The fluid filter is a spin on, full flow unit. Replacementof the filter requires spinning off the cartridge andreplacing it with a new one.

NOTICE!Use genuine Quincy replacement filters only.

Figure 1-3. Spin-on Fluid Filter

The initial filter change should occur after the first 500hours of operation. During normal service, the filtercartridge should be replaced under the followingconditions, whichever occurs first:

• as indicated by the fluid filter maintenance indicatorwhen the fluid is at normal operating temperature

• every 1,000 hours

• every fluid change

NOTICE!The fluid filter maintenance indicator may readhigh upon start up on cool mornings due tosluggish fluid creating higher than normaldifferential pressures. Monitor indicator after thefluid warms up.

Factors Affecting Fluid Life

To protect your investment, check for the following,which can affect the long life of QuinSyn:

1) High operating temperatures2) Contaminants:

a. Other fluidsb. Strong Oxidizers such as:

• acids• sulfur• chlorine• burnt fuel -

i.e. exhaust from: forklifts, boilers, jet aircraft• nitrogen oxides• ozone• welding fumes• plastic molding fumes

c. Ammoniad. Solvent fumes:

• chlorinated degreasers• ink solvents

e. Airborne dust and particlesf. Paper digester fumes

Locate your compressor in the coolest area possible. Forevery 18°F above 195°F, the operating life of any fluid isreduced to about half that at 195°F. Some mineral oilsbegin to form varnish at temperatures above 200°F.QuinSyn fluids are more forgiving than mineral oil at hightemperatures. QuinSyn XP is designed to operate atsustained temperatures above 200°F. The life of otherQuinSyn fluids will be shortened at high temperatures.

Air intake should provide contaminant-free, cool air. AQuincy heavy-duty intake filter will reduce the risk ofabrasion and increased wear. An air filter does noteliminate reactive gases. Inspect your filter monthly andreplace as required.



Fluid Analysis Program - General

Quincy’s fluid analysis program is offered to allcustomers using QuinSyn fluids in Quincy Compressor®

Rotary Screw Compressors. This service providesoptimum drain intervals for compressors operating onQuinSyn fluids. Monitoring of the total acid number(TAN), barium level and/or viscosity throughout the lifeof the fluid provides maximum protection to yourmachine, while best utilizing the extended life features ofQuinSyn.

The fluid analysis provides historical information,detailing items such as hours on the fluid, viscosity andtotal acid number (TAN). Should results appear unusualor suspicious, a detailed analysis can pinpoint specificcontaminants. A detailed report is furnished to you, yourQuincy Distributor and the Quincy Compressor® factoryupon completion of the fluid analysis.

Although QuinSyn fluids are rated by hours of lifeexpectancy under normal operating conditions, it isrecommended that fluid samples be taken every 500 to2000 hours and sent to Quincy Compressor® FluidAnalysis until a history of performance in a specificcompressor application is established. Once theappropriate drain interval is established, the frequency ofthe fluid analysis can be reduced unless operatingconditions change.

NOTICE!All Quincy Compressor® extended airendwarranty programs require that fluid samples besent to Quincy Compressor® Fluid Analysis aminimum of every 2,000 hours.

The depletion of antioxidants, change of viscosity, bariumand acid levels all occur with time. It is extremelyimportant to change QuinSyn before the antioxidants arecompletely depleted. If the fluid is left in the compressorbeyond its useful life, removing all of the spent fluid isdifficult. The oxidation products remaining canconsiderably shorten the life of the new fill of QuinSynfluid.



QuinSyn PG

Effective on orders entered on June 1, 2000 and later,Quincy’s factory fill fluid changed from QuinSyn toQuinSyn PG. Orders placed prior to June 1, 2000shipped with QuinSyn.

QuinSyn PG is a custom blended polyalklene glycol/ester(PAG). QuinSyn PG is an ISO 46 viscosity fluid with an8,000 hour life under normal operating conditions (exactfluid life is determined by the fluid analysis program) andis the chosen fluid for Quincy’s new five-year airendwarranty effective June 1, 2000 (see Blue Alert #566).Under extended warranty conditions QuinSyn PG fluidlife is rated at 8,000 hours or one year, whichever occursfirst.

Typical Properties of QuinSyn PG ISO 46

Viscosity @ 100°F ASTM D445 52.4 cSt.Viscosity @ 210°F ASTM D445 9.4 cSt.Viscosity Index ASTM D2270 163Specific Gravity 60/60 0.98Flash Point ASTM D92 485°FFire Point ASTM D92 525°F

Applications

QuinSyn PG is the recommended fluid in high humidityapplications due to its ability to hold water. QuinSyn PGis best suited for applications where high humidity existsand the machine cannot be shut down to drain water fromthe reservoir.

Disposal

QuinSyn PG is considered nonhazardous waste. Disposalof this fluid should be done in accordance with Local,State, and Federal regulations. Separation of this fluidfrom condensate will require those separators designed tohandle fluid emulsions. The QIOWA fluid/waterseparator is suitable for separation of fluid emulsions suchas QuinSyn PG. Please contact Quincy’s ServiceDepartment for more details.

Fluid Analysis Program

The fluid sampling for QuinSyn PG has been extended to2,000 hours because of the superior quality and forgivingnature of this fluid. The new five-year extended warrantywith QuinSyn PG requires 2,000 hour sampling as acondition of maintaining the warranty.

NOTICE!To maintain warranty compliance, fluid samplesof QuinSyn PG must be sent to QuincyCompressor® Fluid Analysis a minimum of every2,000 hours.

Because this fluid differs from QuinSyn, differentmethods are employed to evaluate the fluid in thesampling program. Primary concerns with this fluid arethe total acid number (TAN) and barium levels. QuinSynPG will not be condemned on water percentage norantioxidants but will be condemned on low barium andhigh TAN values. The barium in the fluid acts as acorrosion inhibitor, therefore we have set low limits forthis additive (see page 52 for limits).



QuinSyn XP

Effective on orders entered on June 1, 2000 and later,Quincy Compressor® began offering QuinSyn XP, along life synthetic fluid. QuinSyn XP is the factory fillfor high pressure units (defined as units over 125 psig fullflow). QuinSyn XP replaces QuinSyn HP 68 as our highpressure fluid and is totally compatible with QuinSyn HP68 (the fluids can be mixed together with absolutely noproblems). Aftermarket pail and drum orders forQuinSyn HP 68 will be filled with QuinSyn XP.

QuinSyn XP is a custom blended polyolester (POE) fluidideally suited for rotary screw air compressors. QuinSynXP is an ISO 68 viscosity fluid with a 12,000 hour life at100 & 125 psig full flow under normal operatingconditions and 8,000 hours as a high pressure fluid (exactfluid life is determined by the fluid sampling program).QuinSyn XP is the only fluid available with Quincy’s ten-year airend warranty (see Blue Alert #566).
