PRE-STARTUP PRECAUTIONS
It is important to your safety that the unit has been properlygrounded during installation. Check ground lug connection in maincontrol box for tightness prior to closing circuit breaker or discon-nect switch. Verify that supply voltage on line side of disconnectagrees with voltage on unit identification plate and is within theutilization voltage range as indicated in Appendix B Electrical Data.
System Voltage - That nominal voltage value assigned to a circuitor system for the purpose of designating its voltage class.
Nameplate Voltage - That voltage assigned to a piece of equip-ment for the purpose of designating its voltage class and for thepurpose of defining the minimum and maximum voltage at whichthe equipment will operate.
11
Utilization Voltage - The voltage of the line terminals of the equip-ment at which the equipment must give fully satisfactory perfor-mance. Once it is established that supply voltage will be main-tained within the utilization range under all system conditions,check and calculate if an unbalanced condition exists betweenphases. Calculate percent voltage unbalance as follows:
Three Phase Models Only
3) PERCENT VOLTAGE UNBALANCE
2) MAXIMUM VOLTAGE DEVIATIONSFROM AVERAGE VOLTAGE
1) AVERAGE VOLTAGE
HOW TO USE THE FORMULA:EXAMPLE: With voltage of 220, 216, and 2131) Average Voltage = 220+216+213=649 / 3 = 2162) Maximum Voltage Deviations from Average Voltage = 220 - 216 = 4
3) Percent Voltage Unbalance = 100 x = = 1.8%
Percent voltage unbalance MUST NOT exceed 2%.

CONTROL VOLTAGE CHECK
With disconnect switch in the open “OFF” position, disconnectblue wire from low voltage transformer TRANS1. Close the discon-nect switch to energize TRANS1 control transformer. Check pri-mary and secondary (24V) of control transformer TRANS1.
AIR FLOW ADJUSTMENTS
NOTE: For 2 Speed Models, airflow adjustments must be made onhigh speed, i.e., 2nd stage cooling or in heat mode.The drive on the supply fan is typically set in the middle of theRPM range. The drive motor sheave pitch diameter is field adjust-able for the required airflow. Refer to the following “DriveAdjustments” section.
When the final adjustments are complete, the current draw of themotor should be checked and compared to the full load currentrating of the motor. The amperage must not exceed the servicefactor stamped on the motor nameplate. The total airflow mustnot be less than that required for operation of the electric heatersor the furnace.
If an economizer is installed, check the unit operating balance withthe economizer at full outside air and at minimum outside air. Uponcompletion of the air flow balancing, we recommend replacingthe variable pitched motor sheave with a properly-sized fixedsheave. A matching fixed sheave will provide longer belt and bear-ing life and vibration free operation. Initially, it is best to have avariable pitched motor sheave for the purpose of airflow balanc-ing, but once the balance has been achieved, fixed sheaves main-tain alignment and minimize vibration more effectively. For directdrive units, move green wire for fan.
NOTE: On “non-two speed models” (two-speed models have a “V”in the eleventh character of the model number), never run CFMbelow 300 CFM per ton. Evaporator freezing or poor unit perfor-mance is possible.
EVAPORATOR FAN ROTATION CHECK (THREE PHASE MODELS ONLY)Check that fan rotates counter-clockwise when viewed from thedrive side of unit and in accordance with rotation arrow shown onblower housing. If it does not, reverse the two incoming powercables. In this case, repeat bearing check.
Do not attempt to change load side wiring. Internal wiring assuresall motors and compressors will rotate in correct direction onceevaporator fan motor rotation check has been made.
ELECTRICAL INPUT CHECK
Make preliminary check of evaporator fan ampere draw and verifythat motor nameplate amps are not exceeded. A final check ofamp draw should be made upon completion of air balancing ofthe duct system (see Appendix B).
SET EVAPORATOR FAN RPMActual RPM’s must be set and verified with a tachometer or strobelight. Refer to Appendices A and B for basic unit fan RPM. Referalso to “Airflow” section of this manual. With disconnect switchopen, disconnect thermostat wires from terminals Y and W. Thiswill prevent heating and mechanical cooling from coming on. Placea jumper wire across terminals R and G at TB1 terminal block. Closedisconnect switch; evaporator fan motor will operate so RPM canbe checked.
START-UP PROCEDURE AND CHECKLIST FOR 2 SPEED MODELS:
Models with a V in the 11th position of the model number.
For 2 speed models, the indoor blower will operate on low speedwhen in “Fan Only” mode or while in first stage “Cooling” mode.Unit will operate on high speed in “Heating” mode and while insecond stage “Cooling” mode.
The start-up procedure is the same as for “Air Conditioning Start-up Procedure” with the understanding that in Step 6, the indoorblower will run at low speed (~1175 motor rpm) and in Step 7, theindoor blower will operate at high speed (~1775 motor rpm).
NOTE: While in the Cooling Mode, to prevent frost from formingon the evaporator while the unit is operating in outdoortemperatures of 65°F or lower, it is recommended that a lowambient kit (LAKT-**) is used. This is strongly recommended for 2Speed models due to the lower airflow while in the first stagecooling. To further protect the compressor from damage duringlow ambient conditions, a Freezestat Kit (FSK01) can be added thatturns the compressor off when the evaporator temperature dropstoo low.
BELT DRIVE MODELS ONLY
The drive on the supply fan is typically set in the middle of theRPM range. The drive motor sheave pitch diameter is field adjust-able for the required airflow. Refer to “Motor Sheave Adjustmens”section.
12
Upon completion of the air flow balancing, we recommend re-placing the variable pitched motor sheave with a properly-sizedfixed sheave. A matching fixed sheave will provide longer belt andbearing life and vibration free operation. Initially, it is best to havea variable pitched motor sheave for the purpose of airflow balanc-ing, but once the balance has been achieved, fixed sheaves main-tain alignment and minimize vibration more effectively. For directdrive units, move fan speed wire.
BEARING CHECK
Prior to energizing any fans, check and make sure that all setscrewsare tight so that bearings are properly secured to shafts.
For heat pump units, the airflow must be adjusted so that the airtemperature rise falls within the ranges given stated on Data Plate(see Appendix A - Blower Performance).
TENSION AND ALIGNMENT ADJUSTMENT
Correct belt tension is very important to the life of your belt. Tooloose a belt will shorten its life; too tight, premature motor andbearing failure will occur. Check you belt drive for adequate “run-in” belt tension by measuring the force required to deflect thebelt at the midpoint of the span length. Belt tension force can bemeasured using a belt tension gauge, available through most beltdrive manufacturers.

When new V-belts are installed on a drive, the initial tension willdrop rapidly during the first few hours of use. Check tension fre-quently during the first 24 hours of operation. Subsequentretentioning should fall between the minimum and maximumforce. To determine the deflection distance from a normal posi-tion, use a straightedge or stretch a cord from sheave to sheave touse as a reference line. On multiple belt drives, an adjacentundeflected belt can be used as a reference.
MOTOR SHEAVE ADJUSTMENTS
VL, VM & 2VP VARIABLE PITCH KEY TYPE MOTOR SHEAVES
The driving and driven motor sheaves should be in alignment witheach other and the shafts parallel.
VL & VM SHEAVES ADJUSTMENT
1. Loosen set screw “B” using a 5/32" Allen key.2. Making half or full turns from closed position, adjust
sheave pitch diameter for desired speed. DO NOT OPENMORE THAN FIVE FULL TURNS.
3. Tighten set screw “B” securely over flat.4. Carefully put on belts and adjust belt tension. DO NOT
FORCE BELTS OVER GROOVES.5. Ensure all keys are in place and the set screws tight before
starting drive. Recheck set screws and belt tension after24 hours service.
NOTE: Future adjustments should be made by loosening the belttension and increasing or decreasing the pitch diameter of thesheave by half or full turns as required. Readjust belt tension beforestarting drive.

HIGH VOLTAGE! DISCONNECT ALL POWER BEFORE SERVICING OR INSTALLING THIS UNIT. MULTIPLE POWER SOURCES MAY BE PRESENT. FAILURE TO DO SO MAY CAUSE PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.
WARNING
HEAT PUMP START-UP PROCEDURE
10. Check the cooling mode for the heat pump in the samemanner as above. The reversing valve is energized whenthe thermostat is placed in the cooling position. A clickingsound should be noticeable from the reversing valve. Bylowering the temperature setting to call for cooling, thecontractor is energized. The compressor, blower and fanshould then be running. After the cooling mode is checkedout, turn the thermostat system switch to “OFF”.
11. Turn the thermostat system switch to “HEAT” and fanswitch to “AUTO”.
12. Slowly raise the heating temperature setting. When theheating first stage makes contact, stop raising thetemperature setting.. The compressor, blower and fanshould now be running with the reversing valve in the de-energized (heating) position. After giving the unit time tosettle out, make sure the unit is supplying heated air.
13. If the outdoor ambient is above 80°F, the unit may trip onits high pressure cut out when on heating. The compressorshould stop. The heating cycle must be thoroughlychecked, so postpone the test to another day whenconditions are more suitable but-DO NOT FAIL TO TEST.If the outdoor ambient is low and the unit operatesproperly on the heating cycle, you may check the pressurecutout operation by blocking off the indoor return air untilthe unit trips.
14. If unit operates properly in the heating cycle, raise thetemperature setting until the heating second stage makescontact. Supplemental resistance heat, if installed shouldnow come on. Make sure it operates properly.NOTE: If outdoor thermostats are installed the outdoorambient must be below the set point of these thermostatsfor the heaters to operate. It may be necessary to jumperthese thermostats to check heater operation if outdoorambient is mild.
14
15. For thermostats with emergency heat switch, return tostep 11. The emergency heat switch is located at thebottom of the thermostat. Move the switch to emergencyheat. The heat pump will stop, the blower will continue torun, all heaters will come on and the thermostatemergency heat light will come on.
16. If checking the unit in the wintertime, when the outdoorcoil is cold enough to actuate the defrost control, observeat least one defrost cycle to make sure the unit defrostscompletely.
FINAL SYSTEM CHECKS
1. Check to see if all supply and return air grilles are adjustedand the air distribution system is balanced for the bestcompromise between heating and cooling.
2. Check for air leaks in the ductwork. See Sections onAir Flow Adjustments.
3. Make sure the unit is free of “rattles”, and the tubing inthe unit is free from excessive vibration. Also make suretubes or lines are not rubbing against each other or sheetmetal surfaces or edges. If so, correct the trouble.
4. Set the thermostat at the appropriate setting for coolingand heating or automatic change over for normal use.
5. Be sure the Owner is instructed on the unit operation, filter,servicing, correct thermostat operation, etc.
REFRIGERATION PERFORMANCE CHECK
Check that compressor RLA corresponds to values shown in Ap-pendix B. RLA draw can be much lower than values listed at lowload conditions and low ambient condensing temperatures. Val-ues in Appendix B can slightly exceed at high load conditions andhigh ambient condensing temperatures.
HEAT PUMP OPERATION
COOLING CYCLE
When the heat pump is in the cooling cycle, it operates exactly asa Summer Air Conditioner unit. In this mode, all the charts anddata for service that apply to summer air conditioning apply tothe heat pump. Most apply on the heating cycle except that “con-denser” becomes “evaporator”, “evaporator” becomes “con-denser”, “cooling” becomes “heating”.
HEATING CYCLE
The heat pump operates in the heating cycle by redirecting refrig-erant flow through the refrigerant circuit external to the compres-sor. This is accomplished with through the reversing valve. Hot dis-charge vapor from the compressor is directed to the indoor coil(evaporator on the cooling cycle) where the heat is removed, andthe vapor condenses to liquid. It then goes through the expansiondevice to the outdoor coil (condenser on the cooling cycle) wherethe liquid is evaporated, and the vapor goes to the compressor.
When the solenoid valve coil is operated either from heating tocooling or vice versa, the piston in the reversing valve to the lowpressure (high pressure) reverse positions in the reversing valve.
The following figures show a schematic of a heat pump on thecooling cycle and the heating cycle. In addition to a reversing valve,a heat pump is equipped with an expansion device and check valvefor the indoor coil, and similar equipment for the outdoor coil. Itis also provided with a defrost control system.
The expansion devices are flowrator distributors and perform thesame function on the heating cycle as on the cooling cycle. Theflowrator distributors also act as check valves to allow for the re-verse of refrigerant flow.
When the heat pump is on the heating cycle, the outdoor coil isfunctioning as an evaporator. The temperature of the refrigerantin the outdoor coil must be below the temperature of the outdoorair in order to extract heat from the air. Thus, the greater thedifference in the outdoor temperature and the outdoor coil tem-perature, the greater the heating capacity of the heat pump. Thisphenomenon is a characteristic of a heat pump. It is a good prac-tice to provide supplementary heat for all heat pump installationsin areas where the temperature drops below 45° F. It is also agood practice to provide sufficient supplementary heat to handlethe entire heating requirement should there be a component fail-ure of the heat pump, such as a compressor, or refrigerant leak,etc.
15
Since the temperature of the refrigerant in the outdoor coil on theheating cycle is generally below freezing point, frost forms on thesurfaces of the outdoor coil under certain weather conditions oftemperature and relative humidity. Therefore, it is necessary toreverse the flow of the refrigerant to provide hot gas in the out-door coil to melt the frost accumulation. This is accomplished byreversing the heat pump to the cooling cycle. At the same time,the outdoor fan stops to hasten the temperature rise of the out-door coil and lessen the time required for defrosting. The indoorblower continues to run and the supplementary heaters are ener-gized.
DEFROST CONTROL
NOTE: DCH models have one stage of mechanical heating. The de-frost accumulation period will start when either first or second stagedefrost thermostat closes. Defrost termination occurs when boththermostats open or the 10 minute cycle has completed.
During operation the power to the circuit board is controlled by atemperature sensor, which is clamped to a feeder tube enteringthe outdoor coil. Defrost timing periods of 30,60 and 90 minutesmay be selected by connecting the circuit board jumper to 30, 60and 90 respectively. Accumulation of time for the timing periodselected starts when the sensor closes (approximately 31° F), andwhen the wall thermostat calls for heat. At the end of the timingperiod, the unit’s defrost cycle will be initiated provided the sen-sor remains closed. When the sensor opens (approximately 75° F),the defrost cycle is terminated and the timing period is reset. Ifthe defrost cycle is not terminated due to the sensor tempera-ture, a ten minute override interrupts the unit’s defrost period.
MAINTENANCE
HIGH VOLTAGE! DISCONNECT ALL POWER BEFORE SERVICING OR INSTALLING THIS UNIT. MULTIPLE POWER SOURCES MAY BE PRESENT. FAILURE TO DO SO MAY CAUSE PROPERTY DAMAGE, PERSONAL INJURY OR DEATH.
WARNING
TO PREVENT PERSONAL INJURY OR DEATH DUE TO IMPROPER INSTALLATION, ADJUSTMENT, ALTERATION, SERVICE OR MAINTENANCE, REFER TO THIS MANUAL. FOR ADDITIONAL ASSISTANCE OR INFORMATION, CONSULT A QUALIFIED INSTALLER, SERVICE AGENCY OR THE GAS SUPPLIER.
WARNING
SHEET METAL PARTS, SCREWS, CLIPS AND SIMILAR ITEMS INHERENTLY HAVE SHARP EDGES, AND IT IS NECESSARY THAT THE INSTALLER AND SERVICE PERSONNEL EXERCISE CAUTION.
CAUTION
The Self Contained Packaged Air Conditioner and Heat Pump shouldoperate for many years without excessive service calls if the unit isinstalled properly. However it is recommended that the home-owner inspect the unit before a seasonal start up. The coils shouldbe free of debris so adequate airflow is achieved. The return andsupply registers should be free of any obstructions. The filtersshould be cleaned or replaced. These few steps will help to keepthe product up time to a maximum. The Service section that fol-lows should help in identifying problems if the unit does not oper-ate properly.
FILTERS
CAUTION
TO PREVENT PROPERTY DAMAGE DUE TO FIRE AND LOSS OFEQUIPMENT EFFICIENCY OR EQUIPMENT DAMAGE DUE TO DUST AND LINTBUILD UP ON INTERNAL PARTS, NEVER OPERATE UNIT WITHOUT AN AIRFILTER INSTALLED IN THE RETURN AIR SYSTEM.
Every application may require a different frequency of replace-ment of dirty filters. Filters must be replaced at least every three(3) months during operating seasons.
Dirty filters are the most common cause of inadequate heating orcooling performance. Filter inspection should be made at leastevery two months; more often if necessary because of local condi-tions and usage.
Dirty throwaway filters should be discarded and replaced with anew, clean filter.
Disposable return air filters are supplied with this unit. See theunit Specification Sheet or Technical Manual for the correct sizeand part number. To remove the filters, remove the filter accesspanel on return side of the unit.
CABINET FINISH MAINTENANCE
Use a fine grade automotive wax on the cabinet finish to maintainthe finish’s original high luster. This is especially important in in-stallations with extended periods of direct sunlight.
16
CLEAN OUTSIDE COIL (QUALIFIED SERVICER ONLY)The coil with the outside air flowing over it should be inspectedannually and cleaned as frequently as necessary to keep the finnedareas free of lint, hair and debris.
LUBRICATION
The fan shaft bearings , the 1 to 2 HP supply fan motors, the con-denser fan motors and compressors are permanently lubricated.
FUNCTIONAL PARTS
Refer to the unit Parts Catalog for a list of functional parts. Partsare available from your distributor.
TROUBLESHOOTING
THE FOLLOWING INFORMATION IS FOR USE BY QUALIFIED SERVICEAGENCY ONLY: OTHERS SHOULD NOT ATTEMPT TO SERVICE THISEQUIPMENT.
Common Causes of Unsatisfactory Operation of Heat Pump on theHeating Cycle.
INADEQUATE AIR VOLUME THROUGH INDOOR COIL
When a heat pump is in the heating cycle, the indoor coil is func-tioning as a condenser. The return air filter must always be clean,and sufficient air volume must pass through the indoor coil to pre-vent excessive discharge pressure, and high pressure cut out.
OUTSIDE AIR INTO RETURN DUCT
Do not introduce cold outside air into the return duct of a heatpump installation. For units with 2-speed motors, do not allow airentering the indoor coil to drop below 65° F. Air below this tem-perature will cause low discharge pressure, thus low suction pres-sure, and excessive defrost cycling resulting in low heating output.It may also cause false defrosting.
UNDERCHARGE
An undercharged heat pump on the heating cycle will cause lowdischarge pressure resulting in low suction pressure and frost ac-cumulation on the outdoor coil.
POOR “TERMINATING” SENSOR CONTACT
The unit’s defrost terminating sensor must make good thermalcontact with the outdoor coil tubing. Poor contact may not termi-nate the unit’s defrost cycle quickly enough to prevent the unitfrom cutting out on high discharge pressure.
MALFUNCTIONING REVERSING VALVE - THIS MAY BE DUE TO:1. Solenoid not energized - In order to determine if the
solenoid is energized, touch the nut that holds the solenoidcover in place with a screwdriver. If the nut magneticallyholds the screwdriver, the solenoid is energized and theunit is in the cooling cycle.
2. No voltage at unit’s solenoid - Check unit voltage. If novoltage, check wiring circuit.
3. Valve will not shift:a. Undercharged - check for leaks;b. Valve Body Damaged - Replace valve;c. Unit Properly Charged - If it is on the heating cycle, raise
the discharge pressure by restricting airflow through theindoor coil. If the valve does not shift, tap it lightly onboth ends with a screwdriver handle. DO NOT TAP THEVALVE BODY. If the unit is on the cooling cycle, raise thedischarge pressure by restricting airflow through theoutdoor coil. If the valve does not shift after the aboveattempts, cut the unit off and wait until the dischargeand suction pressure equalize, and repeat above steps. Ifthe valve does not shift, replace it.
