II. INTRODUCTIONThis booklet contains the installation and operating instructions for your package air con-ditioner. There are a few precautions that should be taken to derive maximum satisfac-tion from it. Improper installation can result in unsatisfactory operation or dangerous con-ditions.
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, electrical characteristics, and accessories to determine ifthey are correct.
IV. SPECIFICATIONSA. GENERALThe Packaged Air Conditioner is available without heat or with 6, 10, 12, 15, 20 or 24kW electric heat. Cooling capacities of 3, 31⁄2 , 4 and 5 nominal tons of cooling are avail-able. Units are convertible from end supply and return to bottom supply and return byrelocation of supply and return air access panels. See cover installation detail.
The units are weatherized for mounting outside of the building.
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 unit includes a hermetically-sealed refrigerating system (consisting of a compressor,condenser coil, evaporator coil with thermal expansion valve), a circulation air blower, acondenser fan, and all necessary internal electrical wiring. The cooling system of theseunits is factory-evacuated, charged and performance tested. Refrigerant amount andtype 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 / TXVThe thermostatic expansion valve is specifically designed to operate with R-410A. DONOT use an R-22 TXV. The existing evaporator must be replaced with the factoryspecified TXV evaporator specifically designed for R-410A.

V. EQUIPMENT PROTECTION FROM THEENVIRONMENT
The 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 contaminents 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.
! CAUTIONR-410A systems operate at higher pressures than R-22 systems. Do not useR-22 service equipment or components on R-410A equipment.
! WARNINGDISCONNECT ALL POWER TO THE UNIT BEFORE STARTING MAINTE-NANCE. FAILURE TO DO SO CAN RESULT IN SEVERE ELECTRICALSHOCK OR DEATH.

VI. INSTALLATIONA. GENERAL
1. PRE-INSTALLATION CHECK-POINTS
Before attempting any installation, the following points should be carefully consid-ered:
a. Structural strength of supporting members.(rooftop installation)
b. Clearances and provision for servicing.c. Power supply and wiring.d. Air duct connections.e. Drain facilities and connections.f. Location for minimum noise.
2. LOCATION
These units are designed for outdoor installations. They can be mounted on aslab or rooftop. They are not to be installed within any part of a structure such asan attic, crawl space, closet, or any other place where condenser air flow isrestricted or other than outdoor ambient conditions prevail. Since the applicationof the units is of the outdoor type, it is important to consult your local code authori-ties at the time the first installation is made.
B. OUTSIDE SLAB INSTALLATION(Typical outdoor slab installations are shown in Figures 5 and 6.)1. Select a location where external water drainage cannot collect around the unit.2. Provide a level concrete slab extending 3" beyond all four sides of the unit. Theslab should be sufficient above grade to prevent ground water from entering theunit. IMPORTANT: To prevent transmission of noise or vibration, slab should notbe connected to building structure.
3. The location of the unit should be such as to provide proper access for inspectionand servicing.
4. Locate unit where operating sounds will not disturb owner or neighbors.5. Locate unit so roof runoff water does not pour directly on the unit. Provide gutteror other shielding at roof level. Do not locate unit in an area where excessivesnow drifting may occur or accumulate.
6. Remove compressor shipping supports (if so equipped) after installation.

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, 2800 Shirlington Road,Suite 300, Arlington, VA 22206, http://www.acca.org.
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" of insulation and a vapor barrier. Distribution system in attic, furred space orcrawl space should be insulated with at least 2" of insulation with vapor barrier. One-halfto 1" thickness of insulation is usually sufficient for ductwork inside the air conditionedspace.
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:1. Noncombustible flexible connectors should be used between ductwork and unit toreduce noise and vibration transmission into the ductwork.
2. When auxiliary heaters are installed, use noncombustible flexible connectors andclearance to combustible material of 0" for the first 3 feet of discharge duct.Clearance to unit top and side is 0".
! WARNINGDO NOT, UNDER ANY CIRCUM-STANCES, CONNECT RETURNDUCTWORK TO ANY OTHER HEATPRODUCING DEVICE SUCH AS AFIREPLACE INSERT, STOVE, ETC.UNAUTHORIZED USE OF SUCHDEVICES MAY RESULT IN FIRE,CARBON MONOXIDE POISONING,EXPLOSION, PROPERTY DAMAGE,SEVERE PERSONAL INJURY ORDEATH.

XII. INDOOR AIR FLOW DATADirect-drive blower models are shipped factory wired for the proper speed at a typicalexternal static. See Blower Performance Data. Belt-drive blower models have motorsheaves set for proper CFM at a typical external static.
XIII. UNITS WITH ECM BLOWER MOTORS(CV & DV MODELS ONLY)The ECM (Brushless permanent magnet) motor used on the blower in this product ispro grammed to operate over a wide range of external static pressures (0.0” - 1.0” W.C.)with essentially constant air flow (CFM). Motor efficiency on ECM type motors is higherthan that of P.S.C. type motors normally used on this type product. See air flow perfor-mance data tables.
The ECM motor is programmed to provide a “soft” start and stop. On a call for heat orcool, the motor will gradually ramp up to the field selected CFM speed. This eliminatesthe sudden rush of air and noise normally associated with a P.S.C. type motor. Once thethermostat and blower delay are satisfied, the motor will gradually ramp down as well.
IMPORTANT: Units equipped with ECM motors cannot be used in by-pass zoningapplica tions.
IMPORTANT: The A.C. power plug to the blower motor has locking tabs. It has beenshown that by applying excessive force to the A.C. cable half of the connector it is possi-ble to force the connector in backwards. It will not seat and “click” properly but will makeconnection. If A.C. power is applied with the connector reversed the motor will be imme-diately destroyed. Do not force power plug into motor connector backwards.
NOTE: Because of the harmonic content of the A.C. Line current to the ECM motor aconven tional ammeter will not read correct motor amps. Only a true RMS meter will giveaccurate AMP readings.
IMPORTANT: The flexibility of ECM motors and the fact that this flexibility is containedin pro grammed memory, not hardware, emphasizes the need for exact motor numbersfor replace ment motors. Because they all look the same, ECM MOTORS FROM DIF-FERENT PROD UCTS OR DIFFERENT MODELS OF THE SAME PRODUCT MUSTNOT BE INTER CHANGED.
IMPORTANT: If an ECM motor is replaced, it is important that the motor be mounted asthe original, as far into the blower wheel as practical for proper motor cooling.
IMPORTANT: The ECM motor is controlled directly from the room thermostat (in allmodes except heating). In cooling, the motor is controlled from the thermostat “Y” termi-nal. When the “Y” or “R” thermostat circuit is opened a 30 second delay will occur beforethe blower motor will cycle. In the heating mode the furnace control board controls theECM through the blower relay. When the “W” thermostat circuits are opened, a 90 sec-ond delay will occur before the blower will cycle off. When the “G” to “R” thermostat cir-cuit is opened for low speed blower, there is no “off’ delay. All thermostat sub-base com-binations as recommended and provided through the Parts Department have been test-ed and are compatible with the ECM motor used in this equipment. Some thermostatsmay not be compatible with the ECM motor provided in this unit. With thermostat in offstate, the voltage on control lines “G”, “Y”, or W with respect to 24 vac common shouldbe less than 3.5 VAC. If the measured voltage is too high, thermostat is incompatiblewith the ECM motor and will cause the motor to run when it should be off.
A. ECM MOTOR INTERFACE CONTROL AND SETTINGSA. (CV & DV UNITS ONLY)The CV & DV series units use ECM blower motors to deliver a constant level of airflowover a wide range of external static pressures (up to 1.5” W.C.). The interface board pro-vides the required communications between the thermostat/IFC and the ECM blowermotor. The inter face board features:
• An automotive-style ATC blade fuse for transformer protection (3 amp).
14
• An on-board LED to indicate blower CFM.• Inputs for two-stages of cooling: Y1 (first stage) and Y2 (second stage)The DIP switches on the interface board are used to define the operation of theECM motor (see Table C).
Refer to Figure 16 for switch identification and factory default settings.
IMPORTANT: Disconnect power to unit when changing DIP switch positions. Even ifblower is not operating, the motor will not recognize changes in DIP switch positionsuntil unit power is removed and then restored.
B. TRANSFORMER PROTECTIONThe ECM interface board is equipped with an automotive-style 3 amp ATC blade fusefor transformer protection. (See Figure 15.) If a short circuit occurs on the secondaryside of the transformer, the fuse will open
C. USING THE ON-BOARD LED TO DETERMINE BLOWER CFMThe ECM interface board LED, which is located in the blower section (see Figure 15),indi cates blower output by flashing. The LED will pause 1/10 second between eachflash. After the blower CFM has been displayed, the LED will illuminate dimly for 10seconds before repeating the sequence. (See Table D.)

10. Adjust discharge air grilles and balance system.
11. Check ducts for condensation and air leaks.
12. Check unit for tubing and sheet metal rattles.
13. Instruct the owner on operation and maintenance.
14. Leave “INSTALLATION” and ”USE AND CARE“ instructions with owner.
XVII. OPERATIONMost single phase units are operated PSC (no start relay or start capacitor). It is impor-tant that such systems be off for a minimum of 5 minutes before restarting to allowequalization of pressures. The thermostat should not be moved to cycle unit withoutwaiting five minutes. To do so may cause the compressor to stop on an automatic openoverload device or blow a fuse. Poor electrical service can cause nuisance tripping inoverloads or blow fuses.
IMPORTANT: The compressor has an internal overload protector. Under some condi-tions, it can take up to 2 hours for this overload to reset. Make sure overload has hadtime to reset before condemning the compressor.
Some units are equipped with a time delay control (TDC1). The control allows the blowerto operate for up to 60 seconds after the thermostat is satisfied.
XVIII. AUXILIARY HEAT
CONTROL SYSTEM OPERATION1. In the cooling mode, the thermostat will, on a call for cooling, energize the compres-sor contactor and the indoor blower relay. The indoor blower can be operated contin-uously by setting the thermostat fan switch at the “ON” position.
2. In the heating mode, the thermostat will energize one or more supplementary resis-tance heaters.
