II. INTRODUCTIONThis booklet contains the installation and operating instructions for your air conditioner.There are a few precautions that should be taken to derive maximum satisfaction from it.Improper installation can result in unsatisfactory operation or dangerous conditions.

Read this booklet and any instructions packaged with separate equipment required tomake up the system prior to installation. Give this booklet to the owner and explain itsprovisions. The owner should retain this booklet for future reference.

III. CHECKING PRODUCT RECEIVEDUpon receiving the unit, inspect it for any damage from shipment. Claims for damage,either shipping or concealed, should be filed immediately with the shipping company.Check the unit model number, heating size, electrical characteristics, and accessories todetermine if they are correct.

IV. EQUIPMENT PROTECTION FROM THEIV. ENVIRONMENTThe metal parts of this unit may be subject to rust or deterioration in adverse environ-mental conditions. This oxidation could shorten the equipment’s useful life. Salt spray,fog or mist in seacoast areas, sulphur or chlorine from lawn watering systems, and vari-ous chemical contaminants from industries such as paper mills and petroleum refineriesare especially corrosive.

If the unit is to be installed in an area where contaminants are likely to be a prob-lem, special attention should be given to the equipment location and exposure.

1. Avoid having lawn sprinkler heads spray direction on the unit cabinet.

2. In coastal areas, locate the unit on the side of the building away from the waterfront.

3. Shielding provided by a fence or shrubs may give some protection.

Regular maintenance will reduce the buildup of contaminants and help to protectthe unit’s finish.

1. Frequent washing of the cabinet, fan blade and coil with fresh water will removemost of the salt or other contaminants that build up on the unit.

2. Regular cleaning and waxing of the cabinet with a good automobile polish will pro-vide some protection.

3. A good liquid cleaner may be used several times a year to remove matter that willnot wash off with water.

Several different types of protective coatings are offered in some areas. These coatingsmay provide some benefit, but the effectiveness of such coating materials cannot be ver-ified by the equipment manufacturer.

The best protection is frequent cleaning, maintenance and minimal exposure tocontaminants.

V. SPECIFICATIONSA. GENERALThe Packaged Air Conditioners are available without heat or with 10, 15, 20, 30, 40 or50 kW electric heat. Cooling capacities of 7.5, 10 or 12.5 nominal tons of cooling areavailable.

! WARNINGDISCONNECT ALL POWER TO THE UNIT BEFORE STARTING MAINTENANCE.FAILURE TO DO SO CAN RESULT IN SEVERE ELECTRICAL SHOCK ORDEATH.

The information on the rating plate is in compliance with the FTC and DOE rating for sin-gle phase units. The following information is for three phase units which are not coveredunder the DOE certification program.

1. The efficiency rating of this unit is a product thermal efficiency rating determinedunder continuous operating conditions independent of any installed system.

B. MAJOR COMPONENTSThe typical unit includes a hermetically-sealed refrigerating system (consisting of a com-pressor, condenser coil, evaporator coil with thermal expansion valve), a circulation airblower, a condenser fan, and all necessary internal electrical wiring. The cooling systemof these units are factory-evacuated, charged and performance tested. Refrigerantamount and type are indicated on rating plate.

C. R-410A REFRIGERANTAll units are factory charged with R-410A refrigerant.

1. Specification of R-410A:

Application: R-410A is not a drop-in replacement for R-22; equipment designs mustaccommodate its higher pressures. It cannot be retrofitted into R-22 units.

Pressure: The pressure of R-410A is approximately 60% (1.6 times) greater thanR-22. Recovery and recycle equipment, pumps, hoses and the like need to have designpressure ratings appropriate for R-410A. Manifold sets need to range up to 800 psighigh-side and 250 psig low-side with a 550 psig low-side retard. Hoses need to have aservice pressure rating of 800 psig. Recovery cylinders need to have a 400 psig servicepressure rating. DOT 4BA400 or DOT BW400.

Combustibility: At pressures above 1 atmosphere, mixture of R-410A and air canbecome combustible. R-410A and air should never be mixed in tanks or supplylines, or be allowed to accumulate in storage tanks. Leak checking should neverbe done with a mixture of R-410A and air. Leak checking can be performed safelywith nitrogen or a mixture of R-410A and nitrogen.

2. Quick Reference Guide For R-410A

• R-410A refrigerant operates at approximately 60% higher pressure (1.6 times) than R-22. Ensure that servicing equipment is designed to operate with R-410A.

• R-410A refrigerant cylinders are pink.• R-410A, as with other HFC’s is only compatible with POE oils.• Vacuum pumps will not remove moisture from POE oil.• R-410A systems are to be charged with liquid refrigerants. Prior to March 1999, R-410A refrigerant cylinders had a dip tube. These cylinders should be kept upright forequipment charging. Post March 1999 cylinders do not have a dip tube and shouldbe inverted to ensure liquid charging of the equipment.

• Do not install a suction line filter drier in the liquid line.• A liquid line filter drier is standard on every unit.• Desiccant (drying agent) must be compatible for POE oils and R-410A.

3. Evaporator Coil / Expansion Device

The expansion device is specifically designed to operate with R-410A. DO NOT use anR-22 device. The existing evaporator must be replaced with the factory specifiedevaporator specifically designed for R-410A.

4. Tools Required For Installing & Servicing R-410A Models

Manifold Sets:-Up to 800 PSIG High side-Up to 250 PSIG Low Side-550 PSIG Low Side Retard

Manifold Hoses:-Service Pressure Rating of 800 PSIG

Recovery Cylinders:-400 PSIG Pressure Rating-Dept. of Transportation 4BA400 or BW400

VII. DUCTWORKDuctwork should be fabricated by the installing contractor in accordance with local codesand NFPA90A. Industry manuals may be used as a guide when sizing and designing theduct system - contact Air Conditioning Contractors of America, 1513 16th St. N.W.,Washington, D.C. 20036.

The unit should be placed as close to the space to be air conditioned as possible allow-ing clearance dimensions as indicated. Ducts should be run as directly as possible tosupply and return outlets. Use of non-flammable waterproof flexible connectors on bothsupply and return connections at the unit to reduce noise transmission is recommended.

It is preferable to install the unit on the roof of the structure if the registers or diffusersare located on the wall or in the ceiling. A slab installation could be considered when theregisters are low on a wall or in the floor.

On ductwork exposed to outside air conditions of temperature and humidity, use a mini-mum of 2" [50.8 mm] of insulation and a vapor barrier. Distribution system in attic, furredspace or crawl space should be insulated with at least 2" [50.8 mm] of insulation withvapor barrier. One-half to 1" [25.4 mm] thickness of insulation is usually sufficient forductwork inside the air conditioned space.

Balancing dampers should be provided for each branch duct in the supply system.Ductwork should be properly supported from the structure.

When installing ductwork, consider the following items:

! WARNINGDO NOT, UNDER ANY CIRCUMSTANCES, CONNECT RETURN DUCTWORK TOANY OTHER HEAT PRODUCING DEVICE SUCH AS A FIREPLACE INSERT,STOVE, ETC. UNAUTHORIZED USE OF SUCH DEVICES MAY RESULT IN FIRE,CARBON MONOXIDE POISONING, EXPLOSION, PROPERTY DAMAGE,SEVERE PERSONAL INJURY OR DEATH.
