On new installations, or if a major component has been re-  
placed, the operation of the unit must be checked.  
Install condensate drain trap as shown. Use 3/4" drain line  
and fittings or larger. Do not operate without trap.  
Check unit operation as outlined in the following instructions.  
If any sparking, odors, or unusual sounds are encountered,  
shut off electrical power and recheck for wiring errors, or ob-  
structions in or near the blower motors. Duct covers must  
be removed before operating unit.  
HORIZONTAL DRAIN  
Drainage of condensate directly onto the roof may be ac-  
ceptable; refer to local code. It is recommended that a small  
drip pad of either stone, mortar, wood or metal be provided to  
prevent any possible damage to the roof.  
The Startup, Adjustments, and Checks procedure provides a  
step-by-step sequence which, if followed, will assure the  
proper startup of the equipment in the minimum amount of  
time. Air balancing of duct system is not considered part of  
this procedure. However, it is an important phase of any air  
conditioning system startup and should be performed upon  
completion of the Startup, Adjustments, and Checks proce-  
dure. The Startup, Adjustments, and Checks procedure at  
outside ambients below 55°F should be limited to a readi-  
ness check of the refrigeration system with the required final  
check and calibration left to be completed when the outside  
ambient rises above 55°F.  
CLEANING  
Due to the fact that drain pans in any air conditioning unit  
will have some moisture in them, algae and fungus will  
grow due to airborne bacteria and spores. Periodic clean-  
ing is necessary to prevent this build-up from plugging the  
drain.

TEMPORARY HEATING OR COOLING  
If the unit is to be used for temporary heating or cooling, a  
“Startup, Adjustments, and Checks” must first be performed  
in accordance with this manual. Failure to comply with this  
requirement will void the warranty. After the machines are  
used for temporary heating or cooling, inspect the coils, fans,  
and motors for unacceptable levels of construction dust and  
dirt and install new filters.

FILTER SECTION CHECK  
ROOF CURB INSTALLATION CHECK  
Remove filter section access panels and check that filters  
are properly installed. Note airflow arrows on filter frames.  
Inspect the roof curb for correct installation. The unit and curb  
assembly should be level. Inspect the flashing of the roof  
mounting curb to the roof, especially at the corners, for good  
workmanship. Also check for leaks around gaskets. Note any  
deficiencies in a separate report and forward to the contrac-  
tor.  
BELT DRIVE MODELS ONLY  
BEARING CHECK  
Prior to energizing any fans, check and make sure that all  
setscrews are tight so that bearings are properly secured to  
shafts.  
OBSTRUCTIONS, FAN CLEARANCE AND WIRING  
Remove any extraneous construction and shipping materi-  
als that may be found during this procedure. Rotate all fans  
manually to check for proper clearances and that they rotate  
freely. Check for bolts and screws that may have jarred loose  
during shipment to the jobsite. Retighten if necessary. Re-  
tighten all electrical connections.  
For heat pump units, the airflow must be adjusted so that the  
air temperature 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.  
Too loose a belt will shorten its life; too tight, premature mo-  
tor and bearing failure will occur. Check you belt drive for  
adequate “run-in” belt tension by measuring the force required  
to deflect the belt at the midpoint of the span length. Belt  
tension force can be measured using a belt tension gauge,  
available through most belt drive manufacturers.  
PRE-STARTUP PRECAUTIONS  
It is important to your safety that the unit has been properly  
grounded during installation. Check ground lug connection  
in main control box for tightness prior to closing circuit breaker  
or disconnect switch. Verify that supply voltage on line side  
of disconnect agrees with voltage on unit identification plate  
and is within the utilization voltage range as indicated in Ap-  
pendix C Electrical Data.

ing and clamps. The entire refrigeration system has been  
factory charged and tested, making it unnecessary to field  
charge. Factory charges are shown on the unit nameplate.  
Install service manifold hoses. Gauges should read satura-  
tion pressure corresponding to ambient temperature. Charge  
should be checked to obtain 12° to 15° of sub-cooling per  
system (i.e. compressor circuits).  
START-UP PROCEDURE AND CHECKLIST  
Begin with power turned off at all disconnects.  
1. Turn thermostat system switch to “Cool,” and fan  
switch to “Auto” and turn temperature setting as high  
as it will go.

RECOMMENDED POUNDS OF FORCE PER BELT  
New V-belts will drop rapidly during the first few hours of use.  
Check tension frequently during the first 24 hours of opera-  
tion. Tension should fall between the minimum and maximum  
force. To determine the deflection distance from a normal  
position, measure the distance from sheave to sheave using  
a straightedge or a cord. This is your reference line. On mul-  
tiple belt drives, an adjacent undeflected belt can be used as  
a reference.  
7. Turn the temperature setting to the highest position,  
stopping the unit. The indoor blower will continue to  
run for 65 seconds.  
8. Turn the thermostat system switch to “OFF” and  
disconnect all power when servicing the unit.

DISCONNECT ALL POWER BEFORE SERVICING OR  
INSTALLING THIS UNIT. MULTIPLE POWER SOURCES MAY

DAMAGE, PERSONAL INJURY OR DEATH.  
Check that fan rotates counter-clockwise when viewed from  
the drive side of unit and in accordance with rotation arrow  
shown on blower housing. If it does not, reverse the two in-  
coming power cables. In this case, repeat bearing check.  
HEAT PUMP START-UP PROCEDURE  
Do not attempt to change load side wiring. Internal wiring  
assures all motors and compressors will rotate in correct di-  
rection once evaporator fan motor rotation check has been  
made.  
9. Check the cooling mode for the heat pump in the same  
manner as above. The reversing valve is energized  
when the thermostat is placed in the cooling position.  
A clicking sound should be noticeable from the  
reversing valve. By lowering the temperature setting  
to call for cooling, the contractor is energized. The  
compressor, blower and fan should then be running.  
After the cooling mode is checked out, turn the  
thermostat system switch to “OFF”.  
ELECTRICAL INPUT CHECK  
Make preliminary check of evaporator fan ampere draw and  
verify that motor nameplate amps are not exceeded. A final  
check of amp draw should be made upon completion of air  
balancing of the duct system (see Appendix B).  
10. Turn the thermostat system switch to “HEAT” and fan  
switch to “AUTO”.  
REFRIGERATION SYSTEM CHECKS  
Ensure the hold-down bolts on the compressor are secure  
and have not vibrated loose during shipment. Check that vi-  
bration grommets have been installed. Visually check all pip-  
12  
11. Slowly raise the heating temperature setting. When  
the heating first stage makes contact, stop raising the  
temperature setting.. The compressor, blower and fan  
should now be running with the reversing valve in the  
de-energized (heating) position. After giving the unit  
time to settle out, make sure the unit is supplying  
heated air.  
12. If the outdoor ambient is above 80°F, the unit may trip  
on its high pressure cut out when on heating. The  
compressor should stop. The heating cycle must be  
thoroughly checked, so postpone the test to another  
day when conditions are more suitable but-DO NOT  
FAIL TO TEST.  
REFRIGERATION PERFORMANCE CHECK  
Under normal summertime (full load) operating conditions,  
superheat should be between 8°F and 12°F and sub-cooling  
measured at the condenser outlet should be 15°F (nominal).  
A 25°F to 35°F temperature difference should exist between  
the entering condenser air and the temperature correspond-  
ing to the compressor saturated discharge pressure. Check  
that compressor RLA corresponds to values shown in Ap-  
pendix C. RLA draw can be much lower than values listed at  
low load conditions and low ambient condensing tempera-  
tures. Values in Appendix C can slightly exceed at high load  
conditions and high ambient condensing temperatures.  
If the outdoor ambient is low and the unit operates  
properly on the heating cycle, you may check the  
pressure cutout operation by blocking off the indoor  
return air until the unit trips.  
HEAT PUMP OPERATION  
COOLING CYCLE  
When the heat pump is in the cooling cycle, it operates ex-  
actly as a Summer Air Conditioner unit. In this mode, all the  
charts and data for service that apply to summer air condi-  
tioning apply to the heat pump. Most apply on the heating  
cycle except that “condenser” becomes “evaporator”, “evapo-  
rator” becomes “condenser”, “cooling” becomes “heating”.  
13. If unit operates properly in the heating cycle, raise  
the temperature setting until the heating second stage  
makes contact. Supplemental resistance heat, if  
installed should now come on. Make sure it operates  
properly.  
NOTE: If outdoor thermostats are installed the  
outdoor ambient must be below the set point of these  
thermostats for the heaters to operate. It may be  
necessary to jumper these thermostats to check  
heater operation if outdoor ambient is mild.  
HEATING CYCLE  
The heat pump operates in the heating cycle by redirecting  
refrigerant flow through the refrigerant circuit external to the  
compressor. This is accomplished with through the reversing  
valve. Hot discharge vapor from the compressor is directed  
to the indoor coil (evaporator on the cooling cycle) where the  
heat is removed, and the vapor condenses to liquid. It then  
goes through the expansion device to the outdoor coil (con-  
denser on the cooling cycle) where the liquid is evaporated,  
and the vapor goes to the compressor.  
14. For thermostats with emergency heat switch, return  
to step 11. The emergency heat switch is located at  
the bottom of the thermostat. Move the switch to  
emergency heat. The heat pump will stop, the blower  
will continue to run, all heaters will come on and the  
thermostat emergency heat light will come on.  
15. If checking the unit in the wintertime, when the outdoor  
coil is cold enough to actuate the defrost control,  
observe at least one defrost cycle to make sure the  
unit defrosts completely.  
When the solenoid valve coil is operated either from heating  
to cooling or vice versa, the piston in the reversing valve to  
the low pressure (high pressure) reverse positions in the re-  
versing valve.  
FINAL SYSTEM CHECKS  
16. Check to see if all supply and return air grilles are  
adjusted and the air distribution system is balanced  
for the best compromise between heating and cooling.  
17. Check for air leaks in the ductwork. See Sections on  
Air Flow Adjustments.  
18. Make sure the unit is free of “rattles”, and the tubing  
in the unit is free from excessive vibration. Also make  
sure tubes or lines are not rubbing against each other  
or sheet metal surfaces or edges. If so, correct the  
trouble.  
The following figures show a schematic of a heat pump on  
the cooling cycle and the heating cycle. In addition to a re-  
versing valve, a heat pump is equipped with an expansion  
device and check valve for the indoor coil, and similar equip-  
ment for the outdoor coil. It is also provided with a defrost  
control system.  
The expansion devices are flowrator distributors and perform  
the same function on the heating cycle as on the cooling cycle.  
The flowrator distributors also act as check valves to allow  
for the reverse of refrigerant flow.  
19. Set the thermostat at the appropriate setting for  
cooling and heating or automatic changeover for  
normal use.  
20. Be sure the Owner is instructed on the unit operation,  
filter, servicing, correct thermostat operation, etc.

DEFROST CONTROL  
COOLING  
SERVICE PORT  
REVERSING VALVE  
During operation the power to the circuit board is controlled  
by a temperature sensor, which is clamped to a feeder tube  
entering the outdoor coil. Defrost timing periods of 30,60 and  
90 minutes may be selected by setting the circuit board jumper  
to 30, 60 and 90 respectively. Accumulation of time for the  
timing period selected starts when the sensor closes (ap-  
proximately 31° F), and when the wall thermostat calls for  
heat. At the end of the timing period, the unit’s defrost cycle  
will be initiated provided the sensor remains closed. When  
the sensor opens (approximately 75° F), the defrost cycle is  
terminated and the timing period is reset. If the defrost cycle  
is not terminated due to the sensor temperature, a twelve  
minute override interrupts the unit’s defrost period.

If an economizer is installed, check the unit operating bal-  
ance with the economizer at full outside air and at minimum  
outside air. Upon completion of the air flow balancing, we  
recommend replacing the variable pitched motor sheave with  
a properly-sized fixed sheave. A matching fixed sheave will  
provide longer belt and bearing life and vibration free opera-  
tion. Initially, it is best to have a variable pitched motor sheave  
for the purpose of airflow balancing, but once the balance  
has been achieved, fixed sheaves maintain alignment and  
minimize vibration more effectively. For direct drive units, move  
green wire for fan.  
When the heat pump is on the heating cycle, the outdoor coil  
is functioning as an evaporator. The temperature of the re-  
frigerant in the outdoor coil must be below the temperature of  
the outdoor air in order to extract heat from the air. Thus, the  
greater the difference in the outdoor temperature and the  
outdoor coil temperature, the greater the heating capacity of  
the heat pump. This phenomenon is a characteristic of a  
heat pump. It is a good practice to provide supplementary  
heat for all heat pump installations in areas where the tem-  
perature drops below 45° F. It is also a good practice to  
provide sufficient supplementary heat to handle the entire  
heating requirement should there be a component failure of  
the heat pump, such as a compressor, or refrigerant leak,  
etc.  
NOTE: Never run CFM below 350 CFM per ton, evaporator  
freezing or poor unit performance is possible.  
PSC MOTOR  
Since the temperature of the refrigerant in the outdoor coil on  
the heating cycle is generally below freezing point, frost forms  
on the surfaces of the outdoor coil under certain weather con-  
ditions of temperature and relative humidity. Therefore, it is  
necessary to reverse the flow of the refrigerant to provide hot  
gas in the outdoor coil to melt the frost accumulation. This is  
accomplished by reversing the heat pump to the cooling cycle.  
At the same time, the outdoor fan stops to hasten the tem-  
perature rise of the outdoor coil and lessen the time required  
for defrosting. The indoor blower continues to run and the  
supplementary heaters are energized.  
Adjust the CFM for the unit by changing the speed tap of the  
indoor blower motor at the EBTDR “com” connection with the  
one of the speed taps on “M1” or “M2” (Black-High Speed,  
Blue-Medium Speed, Red-Low Speed).  
X-13 MOTOR  
Adjust the CFM for the unit by changing the position of the  
low voltage leads on the motor terminal block. Green is for  
Fan Only. Yellow is for Cooling and Heat Pump Heating. Re-  
fer to Appendix A for blower performance at each speed tap.  
NOTE: If more than one lead is energized simultaneously,  
the motor will run at the higher speed.

VL, VM, & 2VP VARIABLE PITCH KEY TYPE MOTOR SHEAVES  
The driving and driven motor sheaves should be in align-  
ment with each other and the shafts parallel.  
The Self Contained PackagedAir Conditioner and Heat Pump  
should operate for many years without excessive service calls  
if the unit is installed properly. However it is recommended  
that the homeowner inspect the unit before a seasonal start  
up. The coils should be free of debris so adequate airflow is  
achieved. The return and supply registers should be free of  
any obstructions. The filters should be cleaned or replaced.  
These few steps will help to keep the product up time to a  
maximum. The Service section that follows should help in  
identifying problems if the unit does not operate properly.  
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  
OPEN MORE 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 after 24 hours service.  
FILTERS  
CAUTION  
NOTE: Future adjustments should be made by loosening the  
belt tension and increasing or decreasing the pitch diameter  
of the sheave by half or full turns as required. Readjust belt  
tension before starting drive.  
TO PREVENT PROPERTY DAMAGE DUE TO FIRE AND LOSS OF

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.  
C
Dirty filters are the most common cause of inadequate heat-  
ing or cooling performance. Filter inspection should be made  
at least every two months; more often if necessary because  
of local conditions and usage.

SERVICE  
THE FOLLOWING INFORMATION IS FOR USE BY QUALI-  
FIED SERVICE AGENCY ONLY: OTHERS SHOULD NOT  
ATTEMPT TO SERVICE THIS EQUIPMENT.  
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  
solenoid cover in place with a screwdriver. If the nut  
magnetically holds the screwdriver, the solenoid is  
energized and the unit is in the cooling cycle.  
2. No voltage at unit’s solenoid - Check unit voltage.  
If no voltage, check wiring circuit.  
Common Causes of Unsatisfactory Operation of Heat Pump  
on the Heating Cycle.  
INADEQUATE AIR VOLUME THROUGH INDOOR COIL  
When a heat pump is in the heating cycle, the indoor coil is  
functioning as a condenser. The return air filter must always  
be clean, and sufficient air volume must pass through the  
indoor coil to prevent excessive discharge pressure, and high  
pressure cut out.  
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 the indoor coil. If the valve does not shift,  
tap it lightly on both ends with a screwdriver handle.  
DO NOT TAP THE VALVE BODY. If the unit is on  
the cooling cycle, raise the discharge pressure by  
restricting airflow through the outdoor coil. If the valve  
does not shift after the above attempts, cut the unit  
off and wait until the discharge and suction pressure  
equalize, and repeat above steps. If the valve does  
not shift, replace it.  
OUTSIDE AIR INTO RETURN DUCT  
Do not introduce cold outside air into the return duct of a heat  
pump installation. Do not allow air entering the indoor coil to  
drop below 65° F. Air below this temperature will cause low  
discharge pressure, thus low suction pressure, and exces-  
sive defrost cycling resulting in low heating output. It may  
also cause false defrosting.
