Verify that the proper blower speeds for heating and cooling
are selected on the blower motor by removing the blower
access panel and inspecting the blower motor, The motor
has 4 speeds numbered "1", "2", "3", and "4", The wires for
the speed selection are as follows:
Red _ Heating
Black _ High Stage Cooling
Violet _ Low Stage Cooling (4 & 5 ton only)
Using the same speed for Heating and Cooling.
If the same speed is required for heating and high stage
cooling the following procedure must be used:
1. Set Red wire on proper speed selection on blower
motor.
2. Remove Black wire from "COOL" (2 - 3.5 Ton models)
or "HI" (4 - 5 Ton Models) on Blower Interface Board.
Tape end of Black lead using electrical tape.
3. Jumper the Red wire to both the "Heat" terminal and
either the "COOL" (2 - 3.5 Ton models) or'HI" (4 - 5Ton
Models) terminal on the Blower Interface Board.
If the same speed is required for heating and low stage
cooling (4 & 5 Ton models only), the following procedure
must be used:
1. Set Red wire on proper speed selection on blower
motor.
2. Remove Violet wire from "LO" on Blower Interface
Board. Tape end of Violet lead using electrical tape.
3. Jumper the Red wire to both the "Heat" terminal and the
"LO" terminal on the Blower Interface Board.
CONTINUOUS FAN OPERATION
Continuous fan speed operates at the cooling speed for 2
th ru 3-1/2 ton models and at the low stage cooling speed for
4 and 5 ton models.
COOLING
1. Turn electric power OFF
2. Set thermostat Heat-Cool select to COOL.
3. Adjust thermostat setting to below room temperature.
4. Turn power ON, for approximately one minute, then
OFF. During power application check the following:
a. Contactor - Contacts Closing
b. Compressor - ON
c. Condenser fan motor - ON
d. Circulating Air Blower - ON 0 second delay
5. Turn power OFE check the following:
a. Contactor contacts opening.
b. Compressor - OFF
c. Condenser fan motor - OFF
d. Circulating blower - OFF after a 60 second delay for
2 thru 3-1/2 ton models and a 90 second delay for 4
and 5 ton models.
