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.

WIRING DIAGRAM BOOKLET AND/OR
INSTALLATION MANUAL FOR WIRING OF
OPTIONAL EQUIPMENT.
TR PRIMARY (HIGH VOLTAGE)
CONNECTIONS: ORANGE WIRE
CONNECTED TO 240V TAP AT THE
FACTORY AND BLACK WIRE TO COM
TERMINAL. FOR 208V SUPPLY POWER,
MOVE ORANGE WIRE FROM 240V TAP TO
THE 208V TAP.
G (GREEN) BLOWER SPEED IS FACTORY
WIRED TO T1. Y1 (YELLOW) AND Y2
(PURPLE) BLOWER SPEEDS ARE
FACTORY WIRED TO T1 AND T3
RESPECTIVELY. W (BROWN) BLOWER
SPEEDS IS FACTORY WIRED TO T2. IF
DIFFERENT SPEEDS ARE NEEDED, SEE
IO MANUAL FOR FURTHER DETAIL ON
BLOWER SPEED TAPS.
IF REFRIGERANT LEAK DETECTION PCB
IS INSTALLED, REMOVE ES-PLM PLUG
(WITH PINK WIRE) AND CONNECT IT TO
RDS-PLF1. THEN, CONNECT RDS-PLM2
TO ES-PLF. REMOVE BM-PLM3 AND
CONNECT LR-PLM TO BM-PLF3.
