ELECTRICAL SHOCK HAZARD.
Failure to follow this warning could result in personal
injury, death and/or property damage.
Turn off electric power supply at disconnect switch or
service panel before removing access or service panels
from unit.
Ifthe same speed is required for gas 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 "HI" on Blower Interface
Board. Tape end of Black lead using electrical tape.
3. Jumper the Red wire to both the "Heat" terminal and
"HI" terminal on the Blower Interface Board.
Verify that the proper blower speeds for heating and cooling Ifthe same speed is required for gas heating and low stage
are selected on the blower motor by removing the blower cooling, the following procedure must be used:
access panel and inspecting the blower motor. The motor 1. Set Red wire on proper speed selection on blower
has up to 5 speeds numbered "1 ", "2", "3", "4", and "5". The
wires for the speed selection are as follows:
Red _ Gas Heating
Black _ High Stage Cooling / High Stage Heat
Pump Heating
Violet miD" Low Stage Cooling / Low Stage Heat
Pump Heating
Using the same speed for Gas Heating and Cooling.
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.
