II. INTRODUCTIONThis booklet contains the installation and operating instructions for your package heatpump. There are a few precautions that should be taken to derive maximum satisfactionfrom 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.
NOTE: A load calculation must be performed to properly determine the requiredheating and cooling for the structure. Also, the duct must be properly designed andinstalled for proper airflow. Existiing ductwork must be inspected for proper size andsealed system. Proper airflow is necessary for both user comfort and equipmentperformance.IMPORTANT: Proper application, installation and maintenance of this equipment isa must if consumers are to receive the full benefit for which they have paid.
A. 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 should beinverted 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.
4. Tools Required For Installing & Servicing R-410A ModelsManifold Sets:
-Up to 800 PSIG High side-Up to 250 PSIG Low Side-550 PSIG Low Side Retard

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 THEENVIRONMENT
The metal parts of this unit may be subject to rust or deterioration in adverse environmen-tal conditions. This oxidation could shorten the equipment’s useful life. Salt spray, fog ormist in seacoast areas, sulphur or chlorine from lawn watering systems, and various chem-ical contaminants from industries such as paper mills and petroleum refineries are espe-cially corrosive.If the unit is to be installed in an area where contaminants are likely to be a problem,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.4. Elevating the unit off its slab or base enough to allow air circulation will help avoidholding water against the basepan.
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 remove mostof the salt or other contaminants that build up on the unit.
2. Regular cleaning and waxing of the cabinet with an automobile polish will providesome protection.
3. A liquid cleaner may be used several times a year to remove matter that will not washoff 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 veri-fied by the equipment manufacturer.The best protection is frequent cleaning, maintenance and minimal exposure tocontaminants.
V. SPECIFICATIONSSuitable for use in mobile homes, manufactured housing, and conventionally constructedresidential and commercial buildings where horizontally-ducted systems are preferred.
VI. INSTALLATIONA. GENERAL
1. PRE-INSTALLATION CHECK-POINTSBefore 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.
! WARNINGDISCONNECT ALL POWER TO THE UNIT BEFORE STARTING MAINTE-NANCE. FAILURE TO DO SO CAN RESULT IN SEVERE ELECTRICAL SHOCKOR DEATH.

B. OUTSIDE SLAB INSTALLATION(Typical outdoor slab installations are shown in Figure 2.)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 not beconnected 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. It is essential that the unit be elevated above the base pad to allow for conden-sate drainage and possible refreezing of condensation. Provide a base pad whichis slightly pitched away from the structure. Route condensate off base pad to anarea which will not become slippery and result in personal injury.
IMPORTANT: Avoid blocking openings in bottom of unit.
7. Where snowfall is anticipated, the height of the unit above the ground level mustbe considered. Mount unit high enough to be above average area snowfall and toallow for proper condensate drainage.
IMPORTANT: Avoid blocking openings in bottom of unit.
C. CLEARANCESThe following minimum clearances must be observed for proper unit performanceand serviceability.
1. Provide 30" minimum clearance at the front and 18" on the right side of the unitfor service access. Provide 12" minimum clearance on the left side of the unit forair inlet.

3. Unit is design certified for application on combustible flooring with 0" minimumclearance.
4. See Figure 2 for illustration of minimum installation-service clearances.
D. ROOFTOP INSTALLATION1. Before locating the unit on the roof, make sure that the strength of the roof andbeams is adequate at that point to support the weight involved. (See specificationsheet for weight of unit.) This is very important and user’s responsibility.
2. The unit should be placed on a solid and level platform of adequate strength.
IMPORTANT: Avoid blocking openings in bottom of unit. (See Figure 3).Provision for disposal of outdoor coil defrost water runoff must be provided.
3. The location of the unit on the roof should be such as to provide proper access forinspection and servicing.
IMPORTANT: If unit will not be put into service immediately, cover supply and returnopenings to prevent excessive condensation.
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.
Place the unit as close to the space to be air conditioned as possible allowing clearancedimensions as indicated. Run ducts as directly as possible to supply and return outlets.Use of non-flammable waterproof flexible connectors on both supply and return connec-tions 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. Consider a slab installation when the registersare 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.
Provide balancing dampers for each branch duct in the supply system. Properly supportthe ductwork from the structure.
VIII.FILTERSFilters are not provided with this unit. They must be supplied and installed in the returnair duct by the installer. A field installed filter grille is recommended for easy and conve-nient access to the filters for periodic inspection and cleaning. Filters must have ade-quate face area for the rated air quantity of the unit. See General Database for recom-mended filter size.
IX. CONDENSATE DRAINThe indoor coil condensate drain ends with a PVC stub. A trap is provided in for propercondensate drainage and to prevent debris from being drawn into the unit. Do not con-nect drain to closed sewer line. It is not recommended that a PVC cement or other per-manent installation be used so that the drain line and/or drain pan can be easily cleanedin the future. The drain trap is located in the control box during shipping. To install, slideclear plastic tube over drain pan connection. The white PVC trap can be oriented asrequired by installation.

F. THERMOSTATMount the thermostat on an inside wall about five feet above the floor in a locationwhere it will not be affected by unconditioned air, sun, or drafts from open doors orother sources. READ installation instructions in heat pump thermostat packageCAREFULLY because each has some different wiring requirements.
XII. INDOOR AIR FLOW DATAAll 208/230 volt units are equipped with multi-speed indoor blower motors. Each unit isshipped factory wired for the proper speed at a normal external static. See AirflowPerformance Table for blower performance.
XIII. PRE-START CHECK1. Is unit properly located and level?2. Is ductwork insulated, weatherproofed, with proper spacing to combustible materi-als?
3. Is air free to travel to and from outdoor coil? (See Figure 1.)
4. Is the wiring correct, tight, and according to unit wiring diagram?
5. Is unit grounded?
6. Are field supplied air filters in place and clean?
7. Do the outdoor fan and indoor blower turn freely without rubbing, and are they tighton the motor shafts?
8. Is unit elevated to allow for outdoor coil condensate drainage during heating opera-tion and defrost?
XIV.STARTUP1. Turn thermostat to “OFF,” turn “on” power supply at disconnect switch.2. Turn temperature setting as high as it will go.3. Turn fan switch to “ON.”4. Indoor blower should run. Be sure it is running in the right direction.5. Turn fan switch to “AUTO.” Turn system switch to “COOL” and turn temperature set-ting below room temperature. Unit should run in cooling mode.
6. Is outdoor fan operating correctly in the right direction?

11. Adjust discharge air grilles and balance system.12. Check ducts for condensation and air leaks.13. Check unit for tubing and sheet metal rattles.14. Instruct the owner on operation and maintenance.15. Leave “USE AND CARE” instructions with owner.
XV. OPERATIONMost single phase units are not equipped with 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. Do not move the thermostat to cycle unit without waiting fiveminutes. To do so may cause the compressor to stop on an automatic open overloaddevice or blow a fuse. Poor electrical service can cause nuisance tripping in overloadsor 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.
These units may be equipped with a time delay control (TDC1). The control allows theblower to operate for 45 to 90 seconds after the thermostat is satisfied.
XVI. AUXILIARY HEATThe amount of auxiliary heat required depends on the heat loss of the structure to beheated and the capacity of the heat pump. It is good practice to install strip heat to main-tain at least 60°F indoor temperatures in case of compressor failure. The auxiliary heatis energized by the first stage of the thermostat. The amount of electric heat that isallowed to come on, as determined by the output of the heat pump, may be controlled byan outdoor thermostat.
A. CONTROL SYSTEM OPERATION1. In the cooling mode, the thermostat will, on a call for cooling, energize the com-pressor contactor and the indoor blower relay. The indoor blower can be operatedcontinuously by setting the thermostat fan switch at the “ON” position.
! WARNINGONLY ELECTRIC HEATER KITS SUPPLIED BY THIS MANUFACTURER ASDESCRIBED IN THIS PUBLICATION HAVE BEEN DESIGNED, TESTED, ANDEVALUATED BY A NATIONALLY RECOGNIZED SAFETY TESTING AGENCYFOR USE WITH THIS UNIT. USE OF ANY OTHER MANUFACTURED ELECTRICHEATERS INSTALLED WITHIN THIS UNIT MAY CAUSE HAZARDOUS CONDI-TIONS RESULTING IN PROPERTY DAMAGE, FIRE, BODILY INJURY ORDEATH.
2. In the heating mode, the first heat stage of the thermostat will energize one ormore supplementary resistance heaters. If required or considered desirable, theresistance heat may also be controlled by outdoor thermostats. In the heatingmode, the thermostat will, on a call for heating, energize the indoor blower relay.
XVII. DEMAND DEFROST CONTROL ANDHIGH/LOW PRESSURE CONTROLSThe demand defrost control is a printed circuit board assembly consisting of solidstate control devices with electro-mechanical outputs. The demand defrost controlmonitors the outdoor ambient temperature, outdoor coil temperature, and the com-pressor run-time to determine when a defrost cycle is required.
Enhanced Feature Demand Defrost Control: Has high and low pressure controlinputs with unique pressure switch logic built into the microprocessor to providecompressor and system protection without nuisance lock-outs. Cycles the compres-sor off for 30 seconds at the beginning and end of the defrost cycle to eliminate theincreased compressor noise caused by rapidly changing system pressures whenthe reversing valve switches. See the end of this section for diagnostic flash codesfor the two diagnostic LED’s provided on the control.
DEFROST INITIATIONA defrost will be initiated when the three conditions below are satisfied:
1) The outdoor coil temperature is below 35°F.
2) The compressor has operated for at least 34 minutes with the outdoor coil tem-perature below 35°F.
3) The measured difference between the ambient temperature and the outdoorcoil temperature is greater than the calculated delta T.
Additionally, a defrost will be initiated if six hours of accumulated compressor run-time has elapsed without a defrost with the outdoor coil temperature below 35°F.
DEFROST TERMINATIONOnce a defrost is initiated, the defrost will continue until fourteen minutes haselapsed or the coil temperature has reached the terminate temperature. The termi-nate temperature is factory set at 70°F, although the temperature can be changedto 50°F, 60°F, 70°F or 80°F by relocating a jumper on the board.
TEMPERATURE SENSORSThe coil sensor is clipped to the outdoor coil. The air sensor is located in the out-door coil compartment.
If the ambient sensor fails the defrost control will initiate a defrost every 34 minuteswith the coil temperature below 35°F.
If the coil sensor fails the defrost control will not initiate a defrost.
TEST MODEThe test mode is initiated by shorting the TEST pins. In this mode of operation, theenable temperature is ignored and all timers are sped up by a factor of 240. To initi-ate a manual defrost, short the TEST pins. Remove the short when the systemswitches to defrost mode. The defrost will terminate on time (14 minutes) or whenthe termination temperature has been achieved. Short TEST pins again to termi-nate the defrost immediately.
TROUBLE SHOOTING DEMAND DEFROSTSet the indoor thermostat select switch to heat and initiate a call for heat.
Jumper the “test pins” to put the unit into defrost. If the unit goes into defrost andcomes back out of defrost, the indication is that the control is working properly.
If the unit did not go into defrost using the test pins, check to ensure that 24V isbeing supplied to the control board. If 24V is present then replace the control.
14
HIGH/LOW PRESSURE CONTROL MONITORING - ENHANCEDDEFROST CONTROLStatus of high and low pressure controls is monitored by the enhanced featuredemand defrost control and the following actions are taken.
High Pressure Control – Provides active protection in both cooling and heatingmodes at all outdoor ambient temperatures. The high pressure control is an auto-matic reset type and opens at approximately 610 psig and closes at approximately420 psig. The compressor and fan motor will stop when the high pressure controlopens and will start again if the high side pressure drops to approximately 420 psigwhen the automatic reset high pressure control resets. If the high pressure controlopens 3 times within a particular call for heating or cooling operation, the defrostcontrol will lock out compressor and outdoor fan operation.
Low Pressure Control – Provides active protection in both heating and coolingmodes at all outdoor ambient temperatures. The low pressure control is an auto-matic reset type and opens at approximately 15 psig and closes at approximately40 psig. Operation is slightly different between cooling and heating modes.
Cooling Mode: The compressor and fan motor will stop when the low pressurecontrol opens and will start again when the low side pressure rises to approxi-mately 40 psig when the low pressure control automatically resets. If the lowpressure switch opens 3 times within a particular call for cooling operation, thedefrost control will lock out compressor and outdoor fan operation.
Heating Mode: The compressor and fan motor will stop when the low pressurecontrol opens and will start again when the low side pressure rises to approxi-mately 40 psig when the low pressure control automatically resets. If the lowpressure switch trips 3 times within 120 minutes of operation during a particularcall for heating operation, the defrost control will lock out compressor and out-door fan operation. If the lock-out due to low pressure occurs at an outdoorambient temperature below 5°F, the defrost control will automatically exit thelock-out mode when the outdoor ambient temperature rises to 5°F. This featureis necessary since the low pressure control could possibly have opened due tothe outdoor ambient being very low rather than an actual system fault.
Exiting Lock-Out Mode: To exit the lock-out mode, remove 24 volts to the defrostcontrol by removing power to indoor air-handler/furnace or by shorting the twodefrost control test pins together.
