WIRING DIAGRAM
NOTES:
1. Disconnect all power before servicing.
2. For supply connections use copper conductors only.
3. Not suitable on systems that exceed 150V to ground.
4. If any of the original wire as supplied with the furnace
must be replaced, it must be replaced with wiring
material having a temperature rating of at least 105°C.
5. For supply wire ampacities overcurrent protection, see
unit rating plate.

DEFROST BOARD OPERATION:
1 CLOSES DURING DEFROST. RAITNG: 1 A MAXIMUM
2 OPENS DURING DEFROST. 2 HP AT 230 VAC MAXIMUM
3 CLOSED WHEN “Y” IS ENERGIZED. OPEN WHEN “Y” IS DEENERGIZED.
PROVIDES “OFF” DELAY TIME OF 5 MIN WHEN “Y” IS DEENERGIZED.
4 WITH DTF CLOSED AND “Y” ENERGIZED, COMPRESSOR RUN TIME IS ACCUMLATED.
OPENING OF DFT DURING DEFROST OR INTERVAL PERIOD RESETS THE INTERVAL TO 0.
NOTE: See Installation
