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.
CONTRACTOR RESPONSIBILITY
WARNING
The installing contractor must be certain that:
•
•
•
All supply and return air ductwork is in place and
corresponds with installation instructions.
All thermostats are mounted and wired in accordance
with installation instructions.
All electric power, all gas, hot water or steam line
connections, and the condensate drain installation
have been made to each unit on the job. These main
supply lines must be functional and capable of
operating all units simultaneously.
MOVING MACHINERY HAZARD!
TO PREVENT POSSIBLE PERSONAL INJURY OR DEATH, DISCONNECT
POWER TO THE UNIT AND PADLOCK IN THE “OFF” POSITION BEFORE
SERVICNG FANS.
HEATING STARTUP
On new installations, or if a major component has been re-
placed, the operation of the unit must be checked.
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.
ROOF CURB INSTALLATION CHECK
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.
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.
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 job site. Retighten if necessary. Re-
tighten all electrical connections.
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.

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.
FILTER SECTION CHECK
Remove filter section access panels and check that filters
are properly installed. Note airflow arrows on filter frames.
BELT DRIVE
BEARING CHECK
Prior to energizing any fans, check and make sure that all
setscrews are tight so that bearings are properly secured to
shafts.
EVAPORATOR FAN ROTATION CHECK (THREE PHASE MODELS
ONLY)
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).
Check that fan rotates 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 at Single Point Power Block. In this case, repeat bear-
ing check.
NOTE: Section on high static tables may require a field motor
change.
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.
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.
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 C).
12
11. Check for air leaks in the ductwork.See Sections on
Air Flow Adjustments.
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-
ing and clamps. The entire refrigeration system has been
factory charged and tested, making it unnecessary to field
charge. Factory charges are shown in Appendix C and on
the unit nameplate.
12. 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.
13. Set the thermostat at the appropriate setting for
cooling and heating or automatic change over for
normal use.
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).
14. Be sure the Owner is instructed on the unit operation,
filter, servicing, correct thermostat operation, etc.
REFRIGERATION PERFORMANCE CHECK
START-UP PROCEDURE AND CHECKLIST
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.
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.
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.
AIR FLOW ADJUSTMENTS
5. Turn the fan switch to “Auto” position. The blower
should stop after a 65 second delay.
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.
6. Slowly lower the cooling temperature until first stage
COOL (LOW COOL) starts. The blower, both fans,
and first stage compressor should now be operating.
Allow the unit to run 10 minutes, make sure cool air is
being supplied by the unit.
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 ex-
ceed the service factor stamped on the motor nameplate.
The total airflow must not be less than that required for op-
eration of the electric heaters or the furnace.
7. Lower the cooling temperature further until second
stage COOL (HIGH COOL) starts. The blower, both
fans, and both compressors should now be operating.
Allow the unit to run 10 minutes, make sure cool air is
being supplied by the unit.
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.
8. Turn the temperature setting to the highest position,
stopping the unit. The indoor blower will continue to
run for 65 seconds.
9. Turn the thermostat system switch to “OFF” and
disconnect all power when servicing the unit.

FINAL SYSTEM CHECKS
10. 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.

MOTOR SHEAVE ADJUSTMENTS
CAUTION
VL, VM & 2VP VARIABLE PITCH KEY TYPE MOTOR SHEAVES
SHEET METAL PARTS, SCREWS, CLIPS AND SIMILAR ITEMS INHERENTLY
HAVE SHARP EDGES, AND IT IS NECESSARY THAT THE INSTALLER AND
SERVICE PERSONNEL EXERCISE CAUTION.
The driving and driven motor sheaves should be in align-
ment with each other and the shafts parallel.
Your 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 SIX 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
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.
CAUTION
TO PREVENT PROPERTY DAMAGE DUE TO FIRE AND LOSS OF
EQUIPMENT EFFICIENCY OR EQUIPMENT DAMAGE DUE TO DUST AND LINT
BUILD UP ON INTERNAL PARTS, NEVER OPERATE UNIT WITHOUT AN AIR
FILTER 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.
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.
B
VL & VM
Dirty throwaway filters should be discarded and replaced with
a new, clean filter.
NOTE: Do not operate sheave with flange projecting beyond
the hub end.
Disposable return air filters are supplied with this unit. See
the unit Specification Sheet or Technical Manual for the cor-
rect size and part number. To remove the filters, remove the
filter access panel on return side of the unit.

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.
CONDENSER, EVAPORATOR, AND INDUCED DRAFT MOTORS
Bearings on the air circulating blower motor, condenser mo-
tor and the combustion fan motor are permanently lubricated.
No additional oiling is required.
UNDERCHARGE
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.
LUBRICATION
The fan shaft bearings, the 1 to 2 HP supply fan motors the
condenser fan motors and compressors are permanently lu-
bricated.
POOR “TERMINATING” SENSOR CONTACT
The unit’s defrost terminating sensor must make good ther-
mal contact with the outdoor coil tubing. Poor contact may
not terminate the unit’s defrost cycle quickly enough to pre-
vent the unit from cutting out on high discharge pressure.
