GENERAL INSTRUCTIONS
IMPORTANTThe equipment covered in this manual is to be installedby trained, experienced service and installationtechnicians. All duct work, supply and return ducts,must be properly sized for the design air flowrequirement of the equipment. ACCA is an excellentguide to proper sizing. All duct work or portions thereofnot in the conditioned space should be properlyinsulated in order to both conserve energy and preventcondensation or moisture damage.
SHIPPING DAMAGEUpon receipt of equipment, the carton should bechecked for external signs of shipping damage. Ifdamage is found, the receiving party must contact thelast carrier immediately, preferably in writing,requesting inspection by the carrier�s agent.
GENERALThe refrigerant system is completely assembled andcharged. All internal wiring is complete.
The unit is designed for use with or without duct work.Flanges are provided for attaching the supply and returnducts.
These instructions explain the recommended method toinstall the air cooled self-contained unit and theelectrical wiring connections to the unit.
These instructions and any instructions packaged withany separate equipment required to make up the entireheat pump system should be carefully read beforebeginning the installation. Note particularly �StartingProcedure� and any tags and/or labels attached to theequipment.
While these instructions are intended as a generalrecommended guide, they do not supersede any nationaland/or local codes in any way. Authorities havingjurisdiction should be consulted before the installation ismade.
FIELD INSTALLED HEATER PACKAGES(OPTIONAL)These packaged air conditions are manufactured withoutsupplementary electric heaters. Supplementary heatersare available for simple, fast field installation.
A separate power circuit is required for thesupplementary heaters.
IMPORTANT: Refer to Table 1 when designing ductwork for maximum available static pressure with heaterinstalled.
Refer to data shown in Table 3 and 4 for properapplication information on all available heatercombinations and what units they can be used with. Italso shows the applicable circuit ampacities, fuse size,and wire size for each heater combination.

INSTALLATION
LOCATION
GENERAL
The unit must be located outside, or in a well ventilatedarea. It must not be in the space being heated or cooled.A sound absorbing material should be considered if theunit is to be installed in such a position or location thatmight cause transmission of sound or vibration to theliving area or adjacent buildings.
SLAB MOUNTING
In areas where winter temperatures DO NOT go below32° F for periods over twelve hours, the unit may beslab mounted at grade level. When installing unit atgrade level, install on a concrete slab at least four inchesabove finished grade level. Slab should have a slopetolerance away from the building structure of at lease 1/4 inch per foot, while being level from side to side.Place slab in a location where runoff water from higherground will not collect around unit. SeeFigure 2.
A minimum of 18 inches should be provided betweenthe coil inlet and any building surfaces. Provide at leastfour feet between coil outlet and any building wall,fences or other vertical structures. Provide a minimumof three feet clearance on the service access side of theunit. See Figure 3.
ROOF MOUNTING
When a unit is installed in areas where low ambienttemperatures or strong winter winds exist, it should beplaced for prevailing winter winds are not in direct linewith the outdoor coil. If this is not possible, a windbarrier should be constructed. Place barrier 24 inchesfrom the coil inlet side of the unit and in the direction ofprevailing winds. Size barrier at least the same heightand width as the unit. This may be necessary on groundlevel installations, also. See Figure 4.
WINTER INSTALLATION BELOW 32°F
In areas where winter conditions go below 32°F forextended periods, the unit must be elevated above themounting surface to prevent snowfall or iceaccumulation from interfering with the operation of theunit. A minimum of twelve inch elevation isrecommended, while greater elevation may be requiredfor areas of high snow accumulation. Poured concrete,steel framework, brick, cement block, etc., can beutilized to construct a suitable raised mounting platform.See Figure 5.
TYPICAL INSTALLATIONS1. ROOF MOUNTED � The unit is mounted on a
sturdy base on the roof of the building. Return air tothe unit is brought through a single return grille(grilles with built-in filters are best since they enableeasy access for filter changing). Return air ducts areattached to the lower section of the front panel.Supply air is brought from the unit to attic duct workor to a furred down hall. Supply air duct is attachedto the top of the front panel.
CAUTION: All outdoor duct work must bethoroughly insulated and weatherproofed. Allattic duct work must be thoroughly insulated.Two inch thick insulation with suitable vaporbarrier is recommended for both outdoor andattic runs.
In roof top installation, as in all installations, the airconditioner must be level from side to side.However, the unit should have a pitch along thelength to assure complete external drainage ofprecipitation and of defrost condensate. See Figures6 and 7, and Tables 6 and 7.
2. CRAWL SPACE � Duct work installed in crawlspace must be well insulated and provided with avapor barrier. In addition, the crawl space must bethoroughly ventilated and provided with a goodvapor barrier as a ground cover. It is most desirableto install the unit will be outdoors rather than insidethe crawl space, so that it will be readily accessiblefor service.
3. SLAB MOUNTED AT GROUND LEVEL � Thistype installation is ideal for homes with a slab floorconstruction where a roof mounted unit is notdesired. The supply and return duct work can be runthrough a furred closet space.
4. THROUGH THE WALL � This type installationrequires a suitable framework to be fabricatedcapable of withstanding the unit weight. Normallythe unit will be insulated so as to minimize supplyand return duct work.

MIS-136
5. OTHER INSTALLATIONS � Many otherinstallations are possible with the packaged airconditioner. No matter what the installation, alwaysconsider the following facts:
A. Insure that the discharge air is not obstructed inany way so as to cause operation difficulties.
B. The indoor coil drain pan is equipped with acoupling that must be piped through acondensate drain trap to a suitable drain.
C. Always mount the unit is such a position that itmay be easily reached for servicing andmaintenance.
D. Insure that the unit is clear so that proper airflow over the outdoor coil will be maintained.
If this unit is operated in cooling below a 65° outdoorambient temperature, the installation of low ambientcontrols (CMA-6) to unit is required.
CONDENSATE DRAIN TRAPIt is very important to provide a trap in the condensatedrain line to allow a positive liquid seal in the line andassure correct drainage from the coil condensate pan.
Install condensate drain trap shown in Figure 8. Usedrain connection size or larger. Do not operate unitwithout trap. Unit must be level or slightly inclinedtoward drain. With a trap installed on a unit located inan unconditioned area, water in the trap may freeze. Itis recommended that the trap material be of a type thatwill allow for expansion of water when it freezes.
AIR FILTERSAir filters for the return air side of the system are notprovided as part of these models, and must be fieldsupplied and installed as part of the final installation.
Prior thought should be given to return air location andplacement of the air filter(s). The air filter(s) must be ofadequate size and readily accessible to the operator ofthe equipment. Filters must be adequate in size andproperly maintained for proper operation. If this is notdone, excessive energy use, poor performance, andmultiple service problems will result. It is impossible tooversize air filters. Generous sizing will result incleaner air and coils as well as lower operating costs andextend the time between required changes. Table 8shows minimum filter areas and recommended filtersizes. Actual filter sizes can vary with the installationdue to single or multiple returns utilizing a filter/grillearrangement or being placed immediately ahead of theindoor coil face in the return air duct.
NOTE: If roof hood accessory is to be used,information on air filters may be found underthat heading in this manual. Air filters aresupplied as part of that package.

TRANSFORMER TAPS230/208V, 1 phase and 3 phase equipment employ dualprimary voltage transformers. All equipment leaves thefactory wired on 240V tap. For 208V operation,reconnect from 240V to 208V tap. The acceptableoperating voltage range for the 240 and 208V taps are:
TAP RANGE 240 253 � 216 208 220 � 187
NOTE: The voltage should be measured at the fieldpower connection point in the unit and whilethe unit is operating at full load (maximumamperage operating condition).
WIRING � MAIN POWERRefer to the unit rating plate for wire sizing informationand maximum fuse size. Each outdoor unit is markedwith a �Minimum Circuit Ampacity�. This means thatthe field wiring used must be sized to carry that amountof current. If field installed heaters are added to thebasic unit, a second separate power supply circuit willbe required. The heater rating plate located adjacent tothe basic unit rating plate will show the appropriatecircuit ampacity fuse size, etc. (Also see �ElectricalSpecifications� on pages 3, 4 and 5.) All models aresuitable for connection with copper wire only. Theseinstructions must be adhered to. Refer to the NationalElectrical Code for complete current carrying capacitydata on the various insulation grades of wiring material.
The electrical specifications list fuse and wire sizes(75°F copper) for all models including the mostcommonly used heater sizes.
The unit rating plate lists a �Maximum Time DelayFuse� or �HACR� type circuit breaker that is to be usedwith the equipment. The correct size must be used forproper circuit protection and also to assure that therewill be no nuisance tripping due to the momentary highstarting current of the compressor.
WIRING � 24V LOW VOLTAGE CONTROLCIRCUITFive (5) wires should be run from thermostat subbase tothe 24V terminal board in the unit. A five conductor, 18gauge copper, color-coded thermostat cable isrecommended. The connection points are shown inFigure 9.
THERMOSTATSSee specific wiring information for the different models, heater KWs, and voltages on unit and heating wiringdiagrams..
IMPORTANT NOTE: Only the thermostat and subbase combinations as shown above will work with thisequipment. The thermostat and subbase MUST be matched, and correct operation can be assured only byproper selection and application of these parts.

START UP AND OPERATION
THREE PHASE SCROLL COMPRESSORSTART UP INFORMATIONScroll compressors, like several other types ofcompressors, will only compress in one rotationaldirection. Direction of rotation is not an issue withsingle phase compressors since they will always startand run in the proper direction.
However, three phase compressors will rotate in eitherdirection depending upon phasing of the power. Sincethere is a 50-50 chance of connecting power in such away as to cause rotation in the reverse direction,verification of proper rotation must be made.Verification of proper rotation direction is made byobserving that suction pressure drops and dischargepressure rises when the compressor is energized.Reverse rotation also results in an elevated sound levelover that with correct rotation, as well as, substantiallyreduced current draw compared to tabulated values.
Verification of proper rotation must be made at thetime the equipment is put into service. If improperrotation is corrected at this time there will be nonegative impact on the durability of the compressor.However, reverse operation for over one hour may havea negative impact on the bearing due to oil pump out.
NOTE: If compressor is allowed to run in reverserotation for several minutes the compressor�sinternal protector will trip.
All three phase ZR*3 compressors are wired identicallyinternally. As a result, once the correct phasing isdetermined for a specific system or installation,connecting properly phased power leads to the sameFusite terminals should maintain proper rotationdirection.
The direction of rotation of the motor may be changedby reversing any two line connections to the unit.
SEQUENCE OF OPERATIONCOOLING � Circuit R-Y makes at thermostat pullingin compressor contactor starting the compressor andoutdoor motor. The G (indoor motor) circuit isautomatically completed on any call for coolingoperation, or can be energized by manual fan switch onsubbase for constant air circulation.
HEATING � A circuit R-W1 is completed on eachheating cycle energizing electric heat if so equipped.
START UP NOTESFor improved start up performance, wash the indoor coilwith dishwasher detergent.
INDOOR BLOWER MOTORSome models feature a variable speed (ECM) motorproviding high efficiency, low sound levels and softstart capabilities. The motor is self adjusting to providethe proper air flow rate at duct static pressures up to0.50� WC without user adjustment or wiring changes.
On command from the wall thermostat the motor willstart slowly and ramp up to full speed over a period of10- 15 seconds.
When the thermostat is satisfied the blower will operatefor approximately 1 minute, and then slow down andstop.
COMPRESSOR CONTROL MODULEThe compressor control is an anti-short cycle/lockouttimer with high and low pressure switch monitoring andalarm output.
ADJUSTABLE DELAY-ON-MAKE AND BREAKTIMEROn a call for compressor operation the delay-on-makeperiod begins which will be 10% of the delay-on-breaksetting. When the delay-on-make is complete and thehigh pressure switch (and low pressure switch ifemployed) is closed, the compressor contactor isenergized. Upon shutdown the delay-on-break timerstarts and prevents restart until the delay-on-break anddelay-on-make periods have expired.
HIGH PRESSURE SWITCH AND LOCKOUTSEQUENCE (Standard Feature)If the high pressure switch opens, the compressorcontactor will de-energize immediately. The lockouttimer will go into a soft lockout and stay in soft lockoutuntil the high pressure switch closes and the delay-on-make time has expired. If the high pressure switchopens again in this same operating cycle the unit will gointo manual lockout condition and the alarm circuit willenergize. Recycling the wall thermostat resets themanual lockout.
Manual 2100-353Page 18
LOW PRESSURE SWITCH, BYPASS, ANDLOCKOUT SEQUENCENOTE: The low pressure switch is an optional control
and the bypass and lockout sequence are partof the standard compressor control module.
If the low pressure switch opens for more that 120seconds, the compressor contactor will de-energize andgo into a soft lockout. Regardless the state of the lowpressure switch, the contactor will reenergize after thedelay-on-make time delay has expired. If the lowpressure switch remains open or opens again for longerthan 120 seconds the unit will go into manual lockoutcondition and the alarm circuit will energize. Recyclingthe wall thermostat resets the manual lockout.
.ALARM OUTPUTAlarm terminal is output connection for applicationswhere alarm signal is desired. This terminal is poweredwhenever compressor is locked out due to HPC or LPCsequences as described.
NOTE: Both high and low pressure switch controls areinherently automatic reset devices. The highpressure switch and low pressure switch cutout and cut in settings are fixed by specific airconditioner or heat pump unit model. Thelockout features, both soft and manual, are afunction of the Compressor Control Module.
ADJUSTMENTS
ADJUSTABLE DELAY-ON-MAKE ANDDELAY-ON-BREAK TIMERThe potentiometer is used to select Delay-on-Break timefrom 30 seconds to 5 minutes. Delay-on-Make (DOM)timing on power-up and after power interruptions isequal to 2 minutes plus 10% of Delay-on-Break (DOB)setting:
0.5 minute (30 seconds) DOB = 123 second DOM1.0 minute (60 seconds) DOB = 126 second DOM2.0 minute (120 seconds) DOB = 132 second DOM3.0 minute (160 seconds) DOB = 138 second DOM4.0 minute (240 seconds) DOB = 144 second DOM5.0 minute (300 seconds) DOB = 150 second DOM

FAN BLADE SETTINGSShown in Figure 10 are the correct fan blade settingdimensions for proper air delivery across the outdoorcoil.
Any service work requiring removal or adjustment inthe fan and/or motor area will require that thedimensions below be checked and blade adjusted in orout on the motor shaft accordingly.
FIGURE 10FAN BLADE SETTING
SERVICE AND TROUBLESHOOTING
SERVICE HINTS1. Caution homeowner to maintain clean air filters at
all times. Also, not to needlessly close off supplyand return air registers. This reduces air flowthrough the system which shortens equipmentservice life as well as increasing operating costs.
2. Check all power fuses or circuit breakers to be surethat they are the correct rating.
3. Periodic cleaning of the outdoor coil to permit fulland unrestricted airflow circulation is essential.
PRESSURE SERVICE PORTSHigh and low pressure service ports are installed on allunits so that the system operating pressures can beobserved. Pressure tables can be found later in thismanual covering all models on cooling cycle. It isimperative to match the correct pressure table to theunit by model number.
REFRIGERANT CHARGEThe correct system R-22 charge is shown on the unitrating plate. Optimum unit performance will occurwith a refrigerant charge resulting in a suction linetemperature (6� from compressor) as shown inTable 11.
TABLE 11SUCTION LINE TEMPERATURES
The above suction line temperatures are based upon80°F dry bulb/67°F wet bulb (50% RH) temperature andrated airflow across the evaporator during cooling cycle.

SUCTION AND DISCHARGE TUBEBRAZINGCompliant Scroll compressors have copper plated steelsuction and discharge tubes. These tubes are far morerugged and less prone to leaks than copper tubes used onother compressors. Due to different thermal propertiesof steel and copper, brazing procedures may have to bechanged from those commonly used.
� To disconnect: heat joint Areas 2 and 3 slowly anduniformly until braze material softens and the tubecan be pulled out of suction fitting. (See Figure 10.)
� To connect:
� Recommended brazing materials: silfos withminimum 5% silver or silver braze material withflux.
� Reinsert tube into fitting.
� Heat tube uniformly in Area 1 moving slowly toArea 2. When joint reaches brazingtemperature, apply brazing material. (SeeFigure 11)
� Heat joint uniformly around the circumferenceto flow braze material completely around thejoint.
� Slowly move torch into Area 3 to draw brazematerial into joint. (See Figure 11.)
� Do not overheat joint.
