GENERAL INSTRUCTIONS
IMPORTANTThe equipment covered in this manual is to be installed bytrained, experienced service and installation technicians.Any heat pump is more critical of proper operating chargeand an adequate duct system than a straight airconditioning unit. All duct work, supply and return ducts,must be properly sized for the design air flow requirementof the equipment. ACCA is an excellent guide to propersizing. All duct work or portions thereof not in theconditioned space should be properly insulated in order toboth conserve energy and prevent condensation ormoisture damage.
SHIPPING DAMAGEUpon receipt of equipment, the carton should be checkedfor external signs of shipping damage. If damage is found,the receiving party must contact the last carrierimmediately, preferably in writing, requesting inspectionby 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 the electricalwiring connections to the unit.
These instructions and any instructions packaged with anyseparate equipment required to make up the entire heatpump system should be carefully read before beginning theinstallation. Note particularly “Starting Procedure” andany tags and/or labels attached to the equipment.
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 heat pumps are manufactured withoutsupplementary electric heaters. Supplementary heaters areavailable for simple, fast field installation.
A separate power circuit is required for the supplementaryheaters.
IMPORTANT: Refer to Table 1 when designing ductwork for maximum available static pressure with heaterinstalled.
Refer to electrical data shown in Tables 3 and 4 for properapplication information on all available heatercombinations and what units they can be used with. It alsoshows the applicable circuit ampacities, fuse size, and wiresize 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. Asound absorbing material should be considered if the unitis to be installed in such a position or location that mightcause transmission of sound or vibration to the living areaor adjacent buildings.
SLAB MOUNTING
In areas where winter temperatures DO NOT go below32° F for periods over twelve hours, the unit may be slabmounted at grade level. When installing unit at gradelevel, install on a concrete slab at least four inches abovefinished grade level. Slab should have a slope toleranceaway from the building structure of at lease 1/4 inch perfoot, while being level from side to side. This will preventice buildup under the unit during defrost cycles. Place slabin a location where runoff water from higher ground willnot collect around unit. See Figure 2.
A minimum of 18 inches should be provided between thecoil inlet and any building surfaces. Provide at least fourfeet between coil outlet and any building wall, fences orother vertical structures. Provide a minimum of three feetclearance on the service access side of the unit. SeeFigure 3
ROOF MOUNTING
When a unit is installed in areas where low ambienttemperatures or strong winter winds exist, it should beplaced so prevailing winter winds are not in direct linewith the heat pump 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 height andwidth as the unit. This may be necessary on ground levelinstallations, 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 defrost iceaccumulation from interfering with the operation of theunit. A minimum of twelve inch elevation isrecommended, while greater elevation may be required forareas of high snow accumulation. Poured concrete, steelframework, brick, cement block, etc., can be utilized toconstruct a suitable raised mounting platform. SeeFigure 5.
TYPICAL INSTALLATIONS
1. ROOF MOUNTED – The unit is mounted on asturdy base on the roof of the building. Return air tothe unit is brought through a single return grille (grilleswith built-in filters are best since they enable easyaccess 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 attached tothe 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 heatpump must be level from side to side. However, theunit should have a pitch along the length to assurecomplete external drainage of precipitation and ofdefrost condensate. See Figures 6 and 7, and Tables 6and 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 good vaporbarrier as a ground cover. It is most desirable to installthe unit outdoors rather than inside the crawl space, sothat it will be readily accessible for service. Inaddition, it is necessary to dispose of the condensatefrom the outdoor coil on the heating cycle, and this isvirtually impossible with the unit installed inside thecrawl space.
3. SLAB MOUNTED AT GROUND LEVEL – Thistype installation is ideal for homes with a slab floorconstruction where a roof mounted unit is not desired.The supply and return duct work can be run through afurred closet space.
4. THROUGH THE WALL – This type installationrequires a suitable framework to be fabricated capableof withstanding the unit weight. Normally the unit willbe insulated so as to minimize supply and return ductwork.

AIR FILTERSAir filters for the return air side of the system are notprovided as part of the various types of applications forthese models, and must be field supplied and installed aspart 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 of theequipment. Filters must be adequate in size and properlymaintained for proper operation. If this is not done,excessive energy use, poor performance, and multipleservice problems will result. It is impossible to oversizeair filters. Generous sizing will result in cleaner air andcoils as well as lower operating costs and extend the timebetween required changes. Table 8 shows minimum filterareas and recommended filter sizes. Actual filter sizes canvary with the installation due to single or multiple returnsutilizing a filter/grille arrangement or being placedimmediately ahead of the indoor coil face in the return airduct.
5. OTHER INSTALLATIONS – Many otherinstallations are possible with the packaged heat pump.No matter what the installation, always consider thefollowing facts:
A. Insure that the discharge air is not obstructed inanyway so as to cause operation difficulties.
B. The indoor coil drain pan is equipped with acoupling that must be piped through a condensatedrain 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 air flowover 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. Use drainconnection size or larger. Do not operate unit withouttrap. Unit must be level or slightly inclined toward drain.
With a trap installed on a unit located in an unconditionedarea, water in the trap may freeze. It is recommended thatthe trap material be of a type that will allow for expansionof water when it freezes.

FIGURE 9LOW VOLTAGE WIRING
WIRING – MAIN POWERRefer to the unit rating plate for wire sizing informationand maximum fuse size. Each outdoor unit is marked witha “Minimum Circuit Ampacity”. This means that the fieldwiring used must be sized to carry that amount of current.If field installed heaters are added to the basic unit, asecond separate power supply circuit will be required. Theheater rating plate located adjacent to the basic unit ratingplate will show the appropriate circuit ampacity fuse size,etc. (Also see “Electrical Data” on pages 3, 4 and 5.) Allmodels are suitable for connection with copper wire only.These instructions must be adhered to. Refer to theNational Electrical Code for complete current carryingcapacity data on the various insulation grades of wiringmaterial.
The unit rating plate lists a “Maximum Time Delay Fuse”or “HACR” type circuit breaker that is to be used with theequipment. The correct size must be used for propercircuit protection and also to assure that there will be nonuisance tripping due to the momentary high startingcurrent of the compressor.
WIRING – 24V LOW VOLTAGE CONTROLCIRCUITTen (10 ) wires should be run from thermostat subbase tothe 24V terminal board in the unit. A nine conductor,18 gauge copper, color-coded thermostat cable isrecommended. The connection points are shown inFigure 9.

THERMOSTAT INDICATOR LAMPSThe red lamp marked “EM. HT.” comes on and stays onwhenever the system switch is placed in Em. Ht. position.The green lamp marked “Check” will come on if there isany problem that prevents the compressor from runningwhen it is supposed to be.
EMERGENCY HEAT POSITIONThe operator of the equipment must manually place thesystem switch in this position. This is done when there is aknown problem with the outdoor section, or when the green“Check” lamp comes on indicating a problem.
TRANSFORMER TAPS230/208V, 1 phase and 3 phase equipment employ dualprimary voltage transformers. All equipment leaves thefactory wired on 240V tap. For 208V operation, reconnectfrom 240V to 208V tap. The acceptable operating voltagerange 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 while theunit is operating at full load (maximumamperage operating condition).
COMPRESSOR CUTOFF THERMOSTATand OUTDOOR THERMOSTAT WIRINGHeat pump compressor operation at outdoor temperaturesbelow 0° F are neither desirable not advantageous in termsof efficiency. Since most equipment at time ofmanufacture is not designated for any specific destinationof the country and most of the equipment is installed inareas not approaching the lower outdoor temperaturerange, the compressor cutoffs are not factory installed.
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 and sizing ofthe heating equipment to the structure. Utilization of theHeating Application Data and the heat loss calculation ofthe building are useful in determining the correct setpoints. Refer to Installation Instructions of CMH-14Outdoor Thermostat Kit for more information.

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 with singlephase compressors since they will always start and run inthe 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 a wayas to cause rotation in the reverse direction, verification ofproper rotation must be made. Verification of properrotation direction is made by observing that suctionpressure drops and discharge pressure rises when thecompressor is energized. Reverse rotation also results inan elevated sound level over that with correct rotation, aswell as, substantially reduced current draw compared totabulated values.
Verification of proper rotation must be made at the timethe equipment is put into service. If improper rotation iscorrected at this time there will be no negative impact onthe durability of the compressor. However, reverseoperation for over one hour may have a negative impact onthe 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, connectingproperly phased power leads to the same Fusite terminalsshould maintain proper rotation direction.
The direction of rotation of the motor may be changed byreversing any two line connections to the unit.
SEQUENCE OF OPERATIONCOOLING – Circuit R-Y makes at thermostat pulling incompressor contactor starting the compressor and outdoormotor. The G (indoor motor) circuit is automaticallycompleted on any call for cooling operation, or can beenergized by manual fan switch on subbase for constant aircirculation.
HEATING – A 24V solenoid coil on reversing valvecontrols heating cycle operation. Two thermostat options,one allowing “AUTO” changeover from cycle to cycle andthe other constantly energizing solenoid coil during heatingseason and thus eliminating pressure equalization noiseexcept during defrost, are to be used. On “AUTO” option,a circuit is completed from R-W1 and R-Y on each heating“On” cycle energizing reversing valve solenoid and pullingin compressor contactor starting compressor and outdoormotor. R-G also make starting indoor blower motor. Heatpump heating cycle now in operation. The secondenergizes the reversing valve solenoid constantly wheneverthe system switch on subbase is placed in “Heat” position,the “B” terminal being constantly energized from R. Athermostat demand for heat completes R-Y circuit, pullingin compressor contactor starting compressor and outdoormotor. R-G also make starting indoor blower motor.
Manual 2100-354Page 20
FIGURE 12HEAT PUMP CONTROL BOARD
MIS-1191
There is also a 5 minute compressortime delay function built into theHPC, This is to protect thecompressor from instances it ishelpful to the service technician tooverride or speed up this timingperiod, and shorting out the speedupterminals for a few seconds can dothis.
DEFROST CYCLEThe defrost cycle is controlled by temperature and time onthe solid state heat pump control. See Figure 12.
When the outdoor temperature is in the lower 40° Ftemperature range or colder, the outdoor coil temperatureis 32° F or below. This coil temperature is sensed by thecoil sensor mounted near the bottom of the outdoor coil.Once coil temperature reaches 30° F or below, the coilsends a signal to the control logic of the heat pump controland the defrost timer will start.
After 30 minutes at 30° F or below, the heat pump controlwill place the system in the defrost mode.
During the defrost mode, the refrigerant cycle switchesback to the cooling cycle, the outdoor motor stops, electricheaters are energized, and hot gas passing through theoutdoor coil melts any accumulated frost. When thetemperature rises to approximately 57° F the coil sensorwill send a signal to the heat pump control which willreturn the system to heating operations automatically.
If some abnormal or temporary condition such as a highwind causes the heat pump to have a prolonged defrostcycle, the heat pump control will restore the system toheating operation automatically after 10 minutes.
There are three settings on the heat pump control – 30minute, 60 minute and 90 minute. Models are shippedwired on the 60 minute setting for greatest operatingeconomy. If special circumstances require a change toanother time, remove wire connected to terminal 60 andreconnect to desired terminal. Refer to Figure 12. Themanufacturer’s recommendation is for 60 minute defrostcycles.
There is a cycle speed up jumper on the control. This canbe used to reduce the time between defrost cycle operationwithout waiting for time to elapse.
Use a small screwdriver or other metallic object, or another1/4 inch QC to short between the SPEEDUP terminals toaccelerate the HPC timer and initiate defrost.
Be careful not to touch any other terminals with instrumentused to short the SPEEDUP terminals. It may take up to10 seconds with the SPEEDUP terminals shorted for thespeedup to be completed and the defrost cycle to start.
As soon as the defrost cycle kicks in remove theshorting instrument from the SPEEDUP terminals.Otherwise the timing will remain accelerated and runthrough the 1 minute maximum defrost length sequence ina matter of seconds and will automatically terminate thedefrost sequence.
There is an initiate defront jumper (sen jump) on thecontrol that can be used at any outdoor ambient during theheating cycle to simulate a 0° coil temperature. This canbe used to check defrost operation of the unit withoutwaiting for the outdoor ambient to fall into the defrostregion.
By placing a jumper across the SEN JMP terminals (a 1/4inch QC terminal works best) the defrost sensor mountedon the outdoor coils is shunted out and will activate thetiming circuit. This permits the defrost cycle to be checkedout in warmer weather conditions without the outdoortemperature having to fall into the defrost region.
In order to terminate the defrost test in the SEN JMPjumper must be removed. If left in place too long thecompressor could stop due to the high pressure controlopening because of the high pressure condition created byoperating in the cooling mode with outdoor fan off.Pressure will rise fairly fast as there is likely no actual froston the outdoor coil in this artificial test condition

SOLID STATE HEAT PUMP CONTROLTROUBLESHOOTING PROCEDURE1. Turn on AC power supply to indoor and outdoor
units.
2. Turn thermostat blower switch to fan on. The indoorblower should start. (If it doesn’t, troubleshootindoor unit and correct problem.)
3. Turn thermostat blower switch to Auto position.Indoor blower should stop.
4. Set system switch to heat or cool. Adjust thermostatto call for heat or cool. The indoor blower,compressor, and outdoor fan should start.
NOTE: If there is no power to 24 volt transformer, thecompressor and outdoor fan motor will not startfor 5 minutes. This is because of thecompressor short cycle protection.

CHECKING TEMPERATURE SENSORCHECK OUT1. 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 or open.
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 the heatpump control.

FAN BLADE SETTINGSShown in Figure 13 are the correct fan blade settingdimensions for proper air delivery across the outdoor coil.
Any service work requiring removal or adjustment in thefan and/or motor area will require that the dimensions inTable 14 be checked and blade adjusted in or out on themotor shaft accordingly.
SERVICE
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 as wellas increasing operating costs.
2. Switching to heating cycle at 75°F or higher outsidetemperature may cause a nuisance trip of the manualreset 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 surethat they are the correct rating.
5. Periodic cleaning of the outdoor coil to permit full andunrestricted 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 in Tables 16through 23 in this manual covering all models on bothcooling and heating cycles. It is imperative to match thecorrect pressure table to the unit by model number.
REFRIGERANT CHARGEThe correct system R-22 charge is shown on the unit ratingplate. Optimum unit performance will occur with arefrigerant charge resulting in a suction line temperature(6” from compressor) as shown in Table 13. FIGURE 13

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 properties ofsteel 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 tube canbe pulled out of suction fitting. (See Figure 14.)
• 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 brazing temperature,apply brazing material. (See Figure 14.)
– Heat joint uniformly around the circumference toflow braze material completely around the joint.
– Slowly move torch into Area 3 to draw brazematerial into joint. (See Figure 14.)
– Do not overheat joint.
