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

DIFFERENT SPEEDS ARE NEEDED,
SEE IO MANUAL FOR FURTHER DETAIL
ON BLOWER SPEED TAPS.
IF REFRIGERANT LEAK DETECTION

PLUG (WITH RED WIRE) AND
CONNECT IT TO RDS-PLF1. THEN,
CONNECT RDS-PLM2 TO ES-PLF.
REMOVE BM-PLM3 AND CONNECT
