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 equipment covered in this manual is to be installedby trained, experienced service and installationtechnicians.

The 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 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 installationis made. See Page 1 for information on codes andstandards.

Size of unit for a proposed installation should be basedon heat loss calculation made according to methods ofAir Conditioning Contractors of America (ACCA). Theair duct should be installed in accordance with theStandards of the National Fire Protection Associationfor the Installation of Air Conditioning and VentilatingSystems of Other Than Residence Type, NFPA No.90A, and Residence Type Warm Air Heating and AirConditioning Systems, NFPA No. 90B. Where localregulations are at a variance with instructions, installershould adhere to local codes.

DUCT WORKAny heat pump is more critical of proper operatingcharge and an adequate duct system than a straight airconditioning unit. All duct work, supply and return,must be properly sized for the design air flowrequirement of the equipment. Air ConditioningContractors of America (ACCA) is an excellent guide toproper sizing. All duct work or portions thereof not inthe conditioned space should be properly insulated inorder to both conserve energy and prevent condensationor moisture damage.

CAUTIONSome installations may not require any returnair duct. A metallic return air grille is requiredwith installations not requiring a return airduct. The spacing between louvers on thegrille shall not be larger than 5/8 inches.

Any grille that meets the 5/8 inch louver criteria, maybe used. It is recommended that Bard Return Air GrilleKit RG-2 thru RG-5 or RFG-2 thru RFG-5 be installedwhen no return duct is used. Contact distributor orfactory for ordering information. If using a return airfilter grille, filters must be of sufficient size to allow amaximum velocity of 400 fpm.

NOTE:If no return air duct is used, applicableinstallation codes may limit this cabinet toinstallation only in a single story structure.

FILTERS

A 1 inch throwaway filter is supplied with each unit.The filter slides into position making it easy to service.This filter can be serviced from the outside by removingthe service door. A 1 inch washable filter and 2 inchpleated filter are also available as optional accessories.The internal filter brackets are adjustable toaccommodate the 2 inch filter by bending down the tabsto allow spacing for the 2 inch filters.

Refer to Table 10 for maximum static pressure availablefor duct design.

Design the duct work according to methods given by theAir Conditioning Contractors of America (ACCA).When duct runs through unheated spaces, it should beinsulated with a minimum of one inch of insulation.Use insulation with a vapor barrier on the outside of theinsulation. Flexible joints should be used to connect theduct work to the equipment in order to keep the noisetransmission to a minimum.

A 1/4 inch clearance to combustible material for the firstthree feet (3') of duct attached to the outlet air frame isrequired. See Wall Mounting Instructions and Figures 4and 4 for further details.

Ducts through the walls must be insulated and all jointstaped or sealed to prevent air or moisture entering thewall cavity.

MIS-938

CONDENSATE DRAIN

A plastic drain hose extends from the drain pan at thetop of the unit down to the unit base. There areopenings in the unit base for the drain hose to passthrough. In the event the drain hose is connected to adrain system of some type, it must be an open or ventedtype system to assure proper drainage.

FRESH AIR INTAKE

All units are built with fresh air inlet slots punched inthe service panel.

If the unit is equipped with the fresh air damperassembly, the assembly is shipped already attached tothe unit. The damper blade is locked in the closedposition. To allow the damper to operate, the maximumand minium blade position stops must be installed. SeeFigure 2.

All capacity, efficiency and cost of operationinformation as required for Department of Energy“Energyguide” Fact Sheets is based upon the fresh airblank-off plate in place and is recommended formaximum energy efficiency.

The blank-off plate is available upon request from thefactory and is installed in place of the fresh air dampershipped with each unit.

BLADE IS LOCKEDCLOSED FORSHIPPING


INSTALLATION INSTRUCTIONS

WALL MOUNTING INFORMATION1. Two holes, for the supply and return air openings,

must be cut through the wall as shown in Figure 3.

2. On wood-frame walls, the wall construction must bestrong and rigid enough to carry the weight of theunit without transmitting any unit vibration. SeeFigures 4 and 5.

WARNINGFire hazard can result if 1/4 inch clearance tocombustible materials for supply air duct is notmaintained. See Figure 3.

3. Concrete block walls must be thoroughly inspected toinsure that they are capable of carrying the weight ofthe installing unit. See Figure 4.

MOUNTING THE UNIT1. These units are secured by wall mounting brackets

which secure the unit to the outside wall surface atboth sides. A bottom mounting bracket is providedfor ease of installation, but it is not required.

2. The unit itself is suitable for “0” inch clearance, butthe supply air duct flange and the first 3 feet ofsupply air duct require a minimum of 1/4 inchclearance to combustible material. If a combustiblewall, use a minimum of 30-1/2" x 10-1/2"dimensions for sizing. However, it is generallyrecommended that a 1 inch clearance is used for easeof installation and maintaining the required clearanceto combustible material. The supply air openingwould then be 32" x 12". SeeFigures 3, 4 and 7 for details.

WARNINGFailure to provide the 1/4 inch clearancebetween the supply duct and a combustiblesurface for the first 3 feet of duct can result infire.

3. Locate and mark lag bolt locations and bottommounting bracket location. See Figure 4.

4. Mount bottom mounting bracket.

5. Hook top rain flashing under back bend of top. Toprain flashing is shipped secured to the right side ofthe back.

6. Position unit in opening and secure with 5/16 lagbolts; use 7/8 inch diameter flat washers on the lagbolts.

7. Secure rain flashing to wall and caulk across entirelength of top. See Figure 3.

8. For additional mounting rigidity, the return air andsupply air frames or collars can be drilled andscrewed or welded to the structural wall itself(depending upon wall construction). Be sure toobserve required clearance if combustible wall.

9. On side by side installations, maintain a minimum of20 inches clearance on right side to allow access toheat strips and control panel, and to allow properairflow to the outdoor coil. Additional clearance maybe required to meet local or national codes.

WIRING — MAIN POWERRefer to the unit rating plate for wire sizinginformation and maximum fuse or “HACR" typecircuit breaker size. Each outdoor unit is markedwith a “Minimum Circuit Ampacity”. This meansthat the field wiring used must be sized to carrythat amount of current. Depending on the installedKW of electric heat, there may be two field powercircuits required. If this is the case, the unit serialplate will so indicate. All models are suitable onlyfor connection with copper wire. Each unit and/orwiring diagram will be marked “Use CopperConductors Only”. These instructions must beadhered to. Refer to the National Electrical Code(NEC) for complete current carrying capacity dataon the various insulation grades of wiring material.All wiring must conform to NEC and all localcodes.

Nine (9) wires should be run from thermostat subbase tothe 24V terminal board in the unit. A nine conductor, 18gauge copper, color-coded thermostat cable isrecommended. The connection points are shown inFigure 7.

IMPORTANT NOTE:Only the thermostat and subbase combinations as shown atthe right will work with this equipment. The thermostat andsubbase must be matched and the correct operation can beassured only by proper selection and application of theseparts.

Note 1: 1F93-380 thermostat must be set to "Heat Pump"mode to operate properly.

Press the program"RUN" button to make sure thethermostat is in run program model.

Press time "FWD" and "BACK" at the same time toenter User Configuration Menu.

Press and hold set "TIME" and "DAY" for about3 seconds to enter Installer Menu.

The thermostat will display "MULTI STG"

Press the "UP" or "DOWN" button until the displayreads "HEAT PUMP"

Press program "RUN" button to resume operation.

NOTE:The voltage should be measured at the field powerconnection point in the unit and while the unit isoperating at full load (maximum amperageoperating condition).

The electrical data lists fuse and wire sizes(75ºC copper) for all models, including themost commonly used heater sizes. Also shownare the number of field power circuits requiredfor the various models with heaters.

The unit rating plate lists a “Maximum TimeDelay Relay Fuse” or “HACR" type circuitbreaker that is to be used with the equipment.The correct size must be used for proper circuitprotection and also to assure that there will beno nuisance tripping due to the momentary highstarting current of the compressor motor.

The disconnect access door on this unit may belocked to prevent unauthorized access to thedisconnect. To convert for the lockingcapability, bend the tab located in the bottomleft hand corner of the disconnect openingunder the disconnect access panel straight out.This tab will now line up with the slot in thedoor. When shut, a padlock may be placedthrough the hole in the tab preventing entry.

THERMOSTAT WIRING

COMPRESSOR CUTOFF THERMOSTAT ANDOUTDOOR THERMOSTATS

Heat pump compressor operation at outdoortemperatures below 0° F are neither desirable noradvantageous in terms of efficiency. Since mostequipment at time of manufacture is not designated forany specific destination of the country and most of theequipment is installed in areas not approaching thelower outdoor temperature range, the compressor cutoffsare not factory installed.

HEAT ANTICIPATIONBoth of the thermostats in Groups A and B below havea fixed heat anticipator for stage 1 with no adjustmentrequired. Stage 2 has an adjustable anticipator for theW2 connection and fixed for the W3 connection. Boththe W2 and W3 circuits are controlled by the stage 2bulb. The only heat anticipator that needs to bechecked is stage 2 and it should be set to match the loadcarried by the W2 circuit. The normal factory wiringprovides for only on electric heat contactor to becontrolled by W2, and the anticipator should be set at.40A. If special field wiring is done, it is best toactually measure the load but a good role is .40A foreach heat contactor controlled by W2.

Outdoor thermostats are available to hold off variousbanks of electric heat until needed as determined byoutdoor temperature. The set point of either type ofthermostat is variable with geographic region andsizing of the heating equipment to the structureUtilization of the Heating Application Data and theheat loss calculation of the building are useful indetermining the correct set points.

IMPORTANT NOTE:Both thermostat and subbase combinations shown above in Groups A and Bincorporate the following features: Man-Auto fan switch, Off-Heat-Cool-Em.Heat switch, and two (2) indicator lamps – one for emergency heat and one forcompressor malfunction.

(1) No automatic changeover position -- must be manually placed in heat or cool.Reversing valve remains energized at all times system switch is in heat position(except during defrost cycle). No pressure equalization noise when thermostat issatisfied on either heating or cooling.

(2) Allows thermostat to control both heating and cooling operation when set in "Auto"position. Reversing valve de-energizes at end of each "On" heating cycle.

THERMOSTAT INDICATOR LAMPSThe red lamp marked "Em. Ht." comes on and stays onwhenever the system switch is placed in the emergencyheat position. The green lamp marked "Check" willcome on if there is any problem that prevents thecompressor from running when it is supposed to be.

EMERGENCY HEAT POSITIONThe operator of the equipment must manually place thesystem switch in this position. This is done when thereis a know problem with the unit, or when the green"Check" lamp comes on indicating a problem.

COMPRESSOR MALFUNCTION LIGHTActuation of the green "Check" lamp is accomplishedby a relay output from the heat pump control boardwhich is factory installed. Any condition such as lossof charge, high head pressure, etc., that will preventcompressor for operating will cause green lamp toactivate. This is a signal to the operator of theequipment to place system in emergency heat position.

START UP

IMPORTANT INSTALLER NOTEFor improved start-up performance, wash the indoorcoil with a dishwashing detergent.

CRANKCASE HEATERSWA421 units are provided with compressor crankcaseheat. WH602 and WH483 units are not provided withcrankcase heat. These units utilize scroll compressorswhich do not require crankcase heat in this application.

The WH421 models have an insertion well-type heaterlocated in the lower section of the compressor housingthis is a self-regulating type heater that draws onlyenough power to maintain the compressor at a safetemperature on these units.

Some form of crankcase heat is essential to preventliquid refrigerant from migrating to the compressor,causing oil pump out on compressor start-up andpossible valve failure due to compressing a liquid.

The decal in Figure 9 is affixed to all WA421 unitsdetailing start-up procedure. This is very important.Please read carefully.

HIGH PRESSURE SWITCHThe WH483 and WH602 models are supplied with aremote reset high pressure switch. If tripped, thispressure switch may be reset by turning the thermostatoff then back on again.

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. All threephase units incorporate a phase monitor to ensure properfield wiring. See the Phase Monitor" on page 15 of thismanual.

Verification of proper rotation must be made any timea compressor is change or rewired. If improper rotationis corrected at this time there will be no negative impacton the durability of the compressor. However, reverseoperation for over one hour may have a negative impacton 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 ZR3 compressors are wired identicalinternally. As a result, once the correct phasing isdetermined for a specific system or installation,connecting properly phased power leads to the sameFusite terminal should maintain proper rotationdirection.

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 rotations, as well as, substantiallyreduced current draw compared to tabulated values.

The direction of rotation of the compressor may bechanged by reversing any two line connections to theunit.

IMPORTANTTHESE PROCEDURES MUST BEFOLLOWED AT INITIAL START UPAND AT ANY TIME POWER HASBEEN REMOVED FOR 12 HOURSOR LONGER.TO PREVENT COMPRESSOR DAMAGEWHICH MAY RESULT FROM THE PRES-ENCE OF LIQUID REFRIGERANT IN THECOMPRESSOR CRANKCASE:

1. MAKE CERTAIN THE ROOM THERMO-STAT IS IN THE “OFF“ POSITION. (THECOMPRESSOR IS NOT TO OPERATE.)

2. APPLY POWER BY CLOSING THESYSTEM DISCONNECT SWITCH.THIS ENERGIZES THE COMPRES-SOR HEATER WHICH EVAPORATESTHE LIQUID REFRIGERANT IN THECRANKCASE.

3. ALLOW 4 HOURS OR 60 MINUTESPER POUND OF REFRIGERANT INTHE SYSTEM AS NOTED ON THEUNIT RATING PLATE, WHICHEVER ISGREATER.

4. AFTER PROPER ELAPSED TIME THETHERMOSTAT MAY BE SET TO OPER-ATE THE COMPRESSOR.

5. EXCEPT AS REQUIRED FOR SAFETYWHILE SERVICING, DO NOT OPENSYSTEM DISCONNECT SWITCH.


now in operation. The second option has no "Auto"changeover position, but instead energizes the reversingvalve solenoid constantly whenever the system switchon subbase is placed in "Heat" position, the "B"terminal being constantly energized from R. AThermostat demand for heat completes r-Y circuit,pulling in compressor contactor starting compressor andoutdoor motor. R-G also make starting indoor blowermotor.

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 themanual covering all models on both cooling and heatingcycles. It is imperative to match the correct pressurecurve to the unit by model number.

DEFROST CYCLEThe defrost cycle is controlled by temperature and timeon the solid state heat pump control.

When the outdoor temperature is in the lower 40° Ftemperature range or colder, the outdoor coiltemperature is 32° F or below. This coil temperature issensed by the coil sensor mounted near the bottom ofthe outdoor coil. Once coil temperature reaches 30° For below, the coil sends a signal to the control logic ofthe heat pump control and the defrost timer will start.

After 60 (90 or 30) minutes at 30° F or below, the heatpump control will place the system in the defrost mode.

During the defrost mode, the refrigerant cycle switchesback to the cooling cycle, the outdoor motor stops,electric heaters are energized, and hot gas passingthrough the outdoor coil melts any accumulated frost.When the temperature rises to approximately 57° F, thecoil sensor will send a signal to the heat pump controlwhich will return the system to heating operationsautomatically.

If some abnormal or temporary conditions such as ahigh wind caused the heat pump to have a prolongeddefrost cycle, the heat pump control will restore thesystem to heating operating automatically after 10minutes.

There is a cycle SPEEDUP jumper on the control. Thiscan be used to reduce the time between defrost cycleoperation without waiting for time to elapse.

Use a small screwdriver or other metallic object, oranother 1/4 inch QC to short between the SPEEDUPterminals to accelerate the HPC timer and initiatedefrost. Be careful not to touch any other terminalswith the instrument used to short the SPEEDUPterminals. It may take up to 10 seconds with theSPEEDUP terminals shorted for the speedup to becompleted and the defrost cycle to start.

SEQUENCE OF OPERATIONCOOLING – Circuit R-Y makes at thermostat pulling incompressor 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 24V solenoid coil on reversing valvecontrols heating cycle operation. Two thermostatoptions, one allowing "Auto" changeover from cycle tocycle and the other constantly energizing solenoid coilduring heating season, and thus eliminating pressureequalization noise except during defrost, are to be used.On "Auto" option a circuit is completed from R-W1 andR-Y on each heating "on" cycle, energizing reversingvalve solenoid and pulling in compressor contactorstarting compressor and outdoor motor. R-G also makestarting indoor blower motor. Heat pump heating cycle

2. Switching to heating cycle at 75° F or higher outsidetemperature may cause a nuisance trip of the remotereset high pressure switch. Turn thermostat off, thenon to reset the high pressure switch.

3. The heat pump wall thermostats perform multiplefunctions. Be sure that all function switches arecorrectly set for the desired operating mode beforetrying to diagnose any reported service problems.

4. Check all power fuses or circuit breakers to be surethey are the correct rating.

5. Periodic cleaning of the outdoor coil to permit full andunrestricted airflow circulation is essential.

SERVICE HINTS1. Caution homeowner to maintain clean air filters at all

times. Also, not to needlessly close off supply andreturn air registers. This reduces air flow through thesystem, which shortens equipment service life aswell as increasing operating costs.

PHASE MONITORAll units with three phase compressors are equippedwith a 3 phase line monitor to prevent compressordamage due to phase reversal.

The phase monitor in this unit is equipped with twoLEDs. If the Y signal is present at the phase monitorand phases are correct, the green LED will light. Ifphases are reversed, the red fault LED will be lit andcompressor operation is inhibited.

If a fault condition occurs, reverse two of the supplyleads to the unit. Do not reverse any of the unit factorywires as damage may occur.


FIGURE 10DEFROST CONTROL BOARD

As soon as the defrost cycle kicks in, remove theshorting instrument from the SPEEDUP terminals.Otherwise the timing will remain accelerated and runthrough the 10-minute maximum defrost lengthsequence in a matter of seconds and will automaticallyterminate the defrost sequence.

There is an initial defrost (SEN JMP) jumper on thecontrol that can be used at any outdoor ambient duringthe heating cycle to simulate a 0° coil temperature.This can be used to check defrost operation of the unitwithout waiting for the outdoor ambient to fall into thedefrost region.

The jumper connection (SEN JMP) on the heat PumpControl (HPC) that can be used during the heating cycleto simulate a 0 degree coil condition and initiate thedefrost sequence. By placing a jumper across theSEN JMP terminals (1/4 inch QC terminal works best)the defrost sensor mounted on the outdoor coil isshunted out and will activate the timing circuit. Thispermits the defrost cycle to be checked out in warmerweather conditions without the outdoor temperaturehaving to fall into the defrost region.

There are three time settings on the HPC — 30, 60 oron minutes. These are elapsed run-time values, and theoutdoor coil temperature sensor must be below the 30degree equivalent resistance value for the timer toaccumulate time towards the actual defrost cycle event.Using the SEN JMP terminals will force the timer torun continuously.

The next event is the actual defrost cycle when thereversing valve shifts the refrigerant system back to thecooling mode, and the outdoor fan motor is turned offto speed the heating of the outdoor coil and melting ofany accumulated frost. The SPEEDUP terminals can beused to reduce the 30,60 or 90 minute real-time periodsto a matter of seconds. Electric heat is typically turnedon to temper the supply air temperature being deliveredinto the building during the defrost cycle.

There is also a 5-minute compressor time delayfunction built into the HPC. This is to protect thecompressor from short cycling conditions. In someinstances it is helpful to the service technician tooverride or speedup this timing period, and shorting outthe SPEEDUP terminals for a few seconds can do this.


TROUBLESHOOTING

SOLID STATE HEAT PUMP CONTROLTROUBLESHOOTING PROCEDURE1. Turn on AC power supply to indoor and outdoor

units.

2. Turn thermostat blower switch to fan "on" – theindoor blower should start. (If it doesn't,troubleshoot indoor unit and correct problem).

3. Turn thermostat blower switch to auto position.Indoor blower should stop.

4. Set system to heat or cool. Adjust thermostat to callfor heat or cool – the indoor blower, compressor,and outdoor fan should start.

NOTE:If there was no power to 24 volt transformer, thecompressor and outdoor fan motor will not startfor 5 minutes. This is because of the compressorshort cycle protection.

CHECKING TEMPERATURE SENSOROUTSIDE UNIT CIRCUIT1. Disconnect temperature sensor from board and from

outdoor coil.

2. Use an ohmmeter and measure the resistance of thesensor. Also use ohmmeter to check for short oropen.

3. Check resistance reading to chart of resistance. Usesensor ambient temperature. (Tolerance of part is± 10%.)

4. If sensor resistance reads very low, then sensor isshorted and will not allow proper operation of theheat pump control.

5. If sensor is out of tolerance, shorted, open or readsvery low ohms then it should be replaced.
