REPLACEMENT WIRE MUST BE SAME SIZE AND TYPE
OF INSULATION AS ORIGINAL (AT LEAST 105° C). USE
COPPER CONDUCTORS ONLY. USE N.E.C. CLASS 2
WIRE FOR ALL LOW VOLTAGE FIELD CONNECTIONS.
IF OPTIONAL ECONOMIZER IS INSTALLED REMOVE
ECON PLM JUMPER AND PLUG IN NEW HARNESS
FROM ECONOMIZER KIT.
IF OPTIONAL ELECTRIC HEAT IS INSTALLED,
PLUG IN NEW HARNESS FROM ELECTRIC
HEATER KIT.
FOR TWO STAGE HEAT, REMOVE
JUMPER ON TB1.
TR1 PRIMARY (HIGH VOLTAGE) CONNECTIONS:
ORANGE WIRE CONNECTED TO 240/460/575V TAP AT
THE FACTORY AND BLACK WIRE TO COM TERMINAL.
FOR 208V SUPPLY POWER, MOVE ORANGE WIRE
FROM 240/460/575V TAP TO THE 208V TAP.
FUSE BLOCKS 1, 2, & 3 ARE OPTIONAL.
IF OPTIONAL SAFETY EQUIPMENT SUCH AS A PHASE
MONITOR, FLOAT SWITCH OR SMOKE DETECTOR IS
INSTALLED, UNPLUG JUMPER PLUG AND PLUG IN
SAFETY DEVICE. IF MULTIPLE SAFETIES ARE
INSTALLED, PLUG IN THE A
DDITIONAL DEVICES IN
SERIES. PLUG IN JUMPER PLUG AT THE LAST SAFETY
DEVICE INSTALLED.
IF A THIRD PARTY SAFETY DEVICE IS FIELD
INSTALLED, CUT THE RED WIRE ON THE
JUMPER PLUG AND WIRE A NORMALLY
CLOSED DRY CONTACT IN SERIES WITH
THE CUT WIRE.
24 VAC ALARM OUTPUT FROM OPTIONAL
ECONOMIZER CONTROL MODULE.
TO CHANGE EVAPORATOR MOTOR SPEED,
MOVE GREEN (FAN ONLY), YELLOW
(COOLING1), PURPLE (COOLING 2), BROWN
(HEATING) OR WHITE (AUX. HEATING)
WIRES TO APP
ROVED SPEED TAP. SEE
INSTALLATION INSTRUCTIONS FOR
FURTHER DETAILS ON ADJUSTING MOTOR.
REMOVE BLACK JUMPER WIRE IF OPTIONAL
FREEZESTAT IS INSTALLED.
MOVE GRAY (GY) WIRE TO TB1-S2 TO
ENABLE T1'-T5' SPEED TAP, SEE TABLE.
