4. The belt drive blower contactor closes its contacts L1,

L2 and L3 to T1, T2 and T3 to provide power to the
supply fan motor.

PSC Motor

Adjust the CFM for the unit by changing the speed
tap of the indoor blower motor at the EBTDR “com”
connection with one of the speed taps on “M1” or “M2”.
(Black-High Speed, Blue-Medium Speed, Red-Low
Speed.)

EEM Motor

Adjust the CFM for the unit by changing the position
of the low voltage leads on the motor terminal block.
White is for fan only and gas heat, Yellow is for cooling.
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.

5. Check supply fan rotation. If the supply fan is rotating

in the wrong direction, disconnect and lock off Single
Point Power Block. Do not attempt to change load
side wiring. Internal wiring is set at the factory to assure
that the supply fan and compressors all rotate in the
proper direction. Verification of correct supply fan
rotation at initial startup will also indicate correct
compressor rotation. Reconnect power and check for
proper operation.

6. Compressor contactor closes its contacts L1, L2 and

L3 to T1, T2 and T3 to provide power to the
compressor motor COMP. 1. In addition, contactor C1
closes its contact L3 to T3 , energizing the condenser
fan motor.

BURN HAZARD!

DO NOT TOUCH! DISCHARGE LINE MAY BE HOT!

WARNING

7. Check that the compressor is operating correctly. The

scroll compressors in these units MUST operate in
the proper rotation. To ensure the compressors are
operating in the correct direction, check the
compressor discharge line pressure or temperature
after the compressor is started.
The discharge pressure and discharge line
temperature should increase.  If this does not occur
and the compressor is producing an exceptional
amount of noise, perform the following checks.

• Ensure all compressors and the supply fan motor
are operating in the proper direction. If a single motor
is operating backwards, check the power wiring for
that motor and correct any leads that have been
interchanged at the contactor or at the motor.
• If all of the motors are operating backward,
disconnect the unit power supply and lock it in the
“OFF” position. Switch two leads of the power supply
at the unit Single Point Power Block. Reconnect
power and check for compressor and supply fan
motor operation.

6. With all safety devices closed, the system will continue

cooling operation until the thermostat is satisfied.

7. Disconnecting the jumper wire between R and Y and

between R and G on TB1 terminal block will simulate
a satisfied thermostat.  The compressor will cycle off
and IIC (pin 12) will initiate its time delay cycle. The
compressor and the supply fan will cycle off.

8. After a time delay of approximately 3 minutes, the

compressor control circuits will be ready to respond
to a subsequent call for cooling from the wall
thermostat.

9. Open disconnect switch. Reconnect the field

thermostat wire at terminal R on terminal block TB1.

HECK

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.

WARNING

NOTE:

Except during brief periods when gas pressures are

being measured by qualified service personnel, the furnace
access panel must always be secured in place when the
furnace is in operation. An inspection port in the access panel
is provided to monitor the flame.

The first step in checking out the gas-fired furnace is to test
the gas supply piping to the unit for tightness and purge the
system of air using methods outlined in the latest edition of
the National Fuel Gas Code ANSI Z223.1.  Verify that the
disconnect switch is in the “OFF” position.  A soapy water
solution should be used to check for gas leaks. Since the unit
is subject to considerable jarring during shipment, it is ex-
tremely important that all gas connections and joints be tested
for tightness. Gas piping downstream from the unit inlet should
be checked for leaks during the subsequent sequence check.

The supply gas pressure should be adjusted to 7.0" w.c. on
natural gas and 11.0" on LP gas with the gas burners operat-
ing. If there is more than one unit on a common gas line, the
pressures should be checked with all units under full fire. A
