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 contractor.
TO PREVENT PROPERTY DAMAGE OR PERSONAL INJURY, DO NOT
START THE UNIT UNTIL ALL NECESSARY PRE-CHECKS AND TESTS
HAVE BEEN PERFORMED.
Prior to the beginning of Startup, Adjustments, and Checks procedures, the following steps should be completed in the building.
OBSTRUCTIONS, FAN CLEARANCE AND WIRING
Remove any extraneous construction and shipping materials 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 job site. Retighten if necessary. Re-tighten all electrical connections.
WARNING
MOVING MACHINERY HAZARD!
TO PREVENT POSSIBLE PERSONAL INJURY OR DEATH, DISCONNECT
POWER TO THE UNIT AND PADLOCK IN THE “OFF” POSITION BEFORE
SERVICNG FANS.
FIELD DUCT CONNECTIONS
HEATING STARTUP
Verify that all duct connections are tight and that there is no air
bypass between supply and return.
On new installations, or if a major component has been replaced,
the operation of the unit must be checked.

FILTER SECTION CHECK
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.
Remove filter section access panels and check that filters are properly installed. Note airflow arrows on filter frames.
PRE-STARTUP PRECAUTIONS
NOTE: Never run CFM below 350 CFM per ton, evaporator freezing
or poor unit performance is possible.
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 Appendix B Electrical Data.
PSC MOTOR
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).
System Voltage - That nominal voltage value assigned to a circuit
or system for the purpose of designating its voltage class.
EEM MOTOR
Nameplate Voltage - That voltage assigned to a piece of equipment for the purpose of designating its voltage class and for the
purpose of defining the minimum and maximum voltage at which
the equipment will operate.
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. Refer 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.
Utilization Voltage - The voltage of the line terminals of the equipment at which the equipment must give fully satisfactory performance. Once it is established that supply voltage will be maintained within the utilization range under all system conditions,
check and calculate if an unbalanced condition exists between
phases. Calculate percent voltage unbalance as follows:
EVAPORATOR FAN ROTATION CHECK (THREE PHASE MODELS ONLY)
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 incoming power
cables. In this case, repeat bearing check.

BELT DRIVE MODELS ONLY
AIR FLOW ADJUSTMENTS
The drive on the supply fan is typically set in the middle of the
RPM range. The drive motor sheave pitch diameter is field adjustable for the required airflow. Refer to “Motor Sheave Adjustmens”
section.
NOTE: For 2 speed models, airflow adjustments must be made on
high speed, i.e., 2nd stage cooling or in heat mode.
The drive on the supply fan is typically set in the middle of the
RPM range. The drive motor sheave pitch diameter is field adjustable for the required airflow. Refer to “Drive Adjustments” section
below.
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 operation. 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 fan speed wire.
When the final adjustments are complete, the current draw of the
motor should be checked and compared to the full load current
rating of the motor. The amperage must not exceed the service
factor stamped on the motor nameplate. The total airflow must
not be less than that required for operation of the electric heaters
or the furnace.
BEARING CHECK
Prior to energizing any fans, check and make sure that all setscrews
are tight so that bearings are properly secured to shafts.
If an economizer is installed, check the unit operating balance 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 operation. Initially, it is best to have a
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).

SET EVAPORATOR FAN RPM
MOTOR SHEAVE ADJUSTMENTS
VL, VM, & 2VP VARIABLE PITCH KEY TYPE MOTOR SHEAVES
Actual RPM’s must be set and verified with a tachometer or strobe
light. Refer to Appendices A and B for basic unit fan RPM. Refer
also to “Airflow” section of this manual. With disconnect switch
open, disconnect thermostat wires from terminals Y and W. This
will prevent heating and mechanical cooling from coming on. Place
a jumper wire across terminals R and G at TB1 terminal block. Close
disconnect switch; evaporator fan motor will operate so RPM can
be checked.
The driving and driven motor sheaves should be in alignment with
each 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 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.
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 motor and
bearing failure will occur. Check you belt drive for adequate “runin” 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.
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.

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 operation.
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 multiple belt drives, an adjacent undeflected belt can be used as a reference.
To confirm charge levels or, if a leak occurs and charge needs to be
added to the system, it is recommended to evacuate the system
and recharge refrigerant to the unit’s nameplate specifications.

START-UP PROCEDURE AND CHECKLIST
Begin with power turned off at all disconnects.
AIR CONDITIONING START-UP PROCEDURE
1. Turn thermostat system switch to “Cool,” and fan switch
to “Auto” and turn temperature setting as high as it will
go.
13.
2. Inspect all registers and set them to the normal open
position.
3. Turn on the electrical supply at the disconnect.
4. Turn the fan switch to the “ON” position. The blower
should operate after a 7 second delay.
5. Turn the fan switch to “Auto” position. The blower should
stop after a 65 second delay.
6. Slowly lower the cooling temperature until the unit starts.
The compressor, blower and fan should now be operating.
Allow the unit to run 10 minutes, make sure cool air is
being supplied by the unit. On 2 stage models, (models
with a “V” in the 11th position) the unit is now operating
on low speed. After the 10 minute run, continue lowering
cooling temperatire until blower speed incresaes indicating
2nd stage cooling. Make sure cool air is still being supplied
by unit and proceed to step 7.
14.
15.
7. Turn the temperature setting to the highest position,
stopping the unit. The indoor blower will continue to run
for 65 seconds.
temperature setting.. The compressor, blower and fan
should now be running with the reversing valve in the deenergized (heating) position. After giving the unit time to
settle out, make sure the unit is supplying heated air.
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.
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.
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.
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.
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.
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.
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.
8. Turn the thermostat system switch to “OFF” and
disconnect all power when servicing the unit.

HEAT PUMP START-UP PROCEDURE
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”.
10. Turn the thermostat system switch to “HEAT” and fan
switch to “AUTO”.
11. Slowly raise the heating temperature setting. When the
heating first stage makes contact, stop raising the
REFRIGERATION PERFORMANCE CHECK
Check that compressor RLA corresponds to values shown in Appendix B. RLA draw can be much lower than values listed at low
load conditions and low ambient condensing temperatures. Values in Appendix B can slightly exceed at high load conditions and
high ambient condensing temperatures.

HEAT PUMP OPERATION
COOLING CYCLE
When the heat pump is in the cooling cycle, it operates exactly as
a Summer Air Conditioner unit. In this mode, all the charts and
data for service that apply to summer air conditioning apply to
the heat pump. Most apply on the heating cycle except that “condenser” becomes “evaporator”, “evaporator” becomes “condenser”, “cooling” becomes “heating”.
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 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 (condenser on the cooling cycle) where
the liquid is evaporated, and the vapor goes to the compressor.
When the heat pump is on the heating cycle, the outdoor coil is
functioning as an evaporator. The temperature of the refrigerant
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 temperature 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.
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 reversing valve.
The following figures show a schematic of a heat pump on the
cooling cycle and the heating cycle. In addition to a reversing valve,
a heat pump is equipped with an expansion device and check valve
for the indoor coil, and similar equipment for the outdoor coil. It
is also provided with a defrost control system.
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 conditions 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 temperature rise of the outdoor coil and lessen the time required for defrosting. The indoor
blower continues to run and the supplementary heaters are energized.
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.
DEFROST CONTROL
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 connecting the circuit board jumper to 30, 60
13
and 90 respectively. Accumulation of time for the timing period
selected starts when the sensor closes (approximately 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 ten minute override interrupts the unit’s defrost period.
Dirty throwaway filters should be discarded and replaced with a
new, clean filter.
Disposable return air filters are supplied with this unit. See the
unit Specification Sheet or Technical Manual for the correct size
and part number. To remove the filters, remove the filter access
panel on return side of the unit.
CABINET FINISH MAINTENANCE
Use a fine grade automotive wax on the cabinet finish to maintain
the finish’s original high luster. This is especially important in installations with extended periods of direct sunlight.

Common Causes of Unsatisfactory Operation of Heat Pump on the
Heating Cycle.
The Self Contained Packaged Air 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.
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.
OUTSIDE AIR INTO RETURN DUCT
Do not introduce cold outside air into the return duct of a heat
pump installation. For units with 2-speed motors, 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 excessive defrost cycling resulting in low heating output.
It may also cause false defrosting.
FILTERS
CAUTION
TO PREVENT PROPERTY DAMAGE DUE TO FIRE AND LOSS OF
UNDERCHARGE
EQUIPMENT EFFICIENCY OR EQUIPMENT DAMAGE DUE TO DUST AND LINT
BUILD UP ON INTERNAL PARTS, NEVER OPERATE UNIT WITHOUT AN AIR
An undercharged heat pump on the heating cycle will cause low
discharge pressure resulting in low suction pressure and frost accumulation on the outdoor coil.
FILTER INSTALLED IN THE RETURN AIR SYSTEM.
Every application may require a different frequency of replacement of dirty filters. Filters must be replaced at least every three
(3) months during operating seasons.
POOR “TERMINATING” SENSOR CONTACT
The unit’s defrost terminating sensor must make good thermal
contact with the outdoor coil tubing. Poor contact may not terminate the unit’s defrost cycle quickly enough to prevent the unit
from cutting out on high discharge pressure.
Dirty filters are the most common cause of inadequate heating or
cooling performance. Filter inspection should be made at least
every two months; more often if necessary because of local conditions and usage.

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.
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.
