NOTES
1. REPLACEMENT WIRE MUST BE THE SAME SIZE AND TYPE OF
INSULATION AS ORIGINAL (AT LEAST 105°C). USE COPPER
CONDUCTOR ONLY.
2. FOR 208V TRANSFORMER OPERATION MOVE BLACK WIRE FROM
TERMINAL 3 TO TERMINAL 2 ON TRANSFORMER.
3. FOR 208V VENT MOTOR OPERATION, REMOVE BLUE LEAD FROM
INDUCER LOW TERMINAL. MOVE BLACK LEAD FROM PARK TERMINAL
TO INDUCER LOW TERMINAL, AND PLACE BLUE LEAD ON PARK.
4. USE COPPER CONDUCTORS ONLY.
++
USE NEC CLASS 2 WIRE.
5. FOR OUTDOOR THERMOSTAT, REMOVE PLUG FROM HARNESS AND
CONNECT PLUG FROM OUTDOOR THERMOSTAT TO HARNESS.
6. TO CHANGE AIRFLOW MOVE YELLOW WIRE (COOLING / HEAT PUMP),
WHITE WIRE (LOW STAGE GAS), OR BROWN WIRE (HIGH-STAGE GAS)

REFER TO UNIT AIRFLOW TABLES FOR TO DETERMINE THE
APPROPRIATE SPEED TAP FOR APPLICATION. UNITS SHIPPED WITH
YELLOW, WHITE, AND BROWN ON T4, T1, AND T2 RESPECTIVELY.
7. CRANKCASE HEATER AND CRANKCASE HEATER SWITCH FACTORY
EQUIPPED WHEN REQUIRED.
