WIRING DIAGRAM
NOTES:
1. Disconnect all power before servicing.
2. For supply connections use copper conductors only.
3. Not suitable on systems that exceed 150 volts to ground.
4. For replacement wires use conductors suitable for 105˚C.
Defrost Board Operation:
1. Closing during defrost. Rating: 1 Amp.Max
2. Opens during defronst. Rating: 2HP at 230 Vac Max.
3. Closed when “Y” is on. Open when “Y” is off.
Provides “off” delay time of 5 min. when “Y” opens.
4. With DFT closed and “Y” closed, compressor run
time is accumulated. Opening of DFT during
defrost or interval period resets the interval to 0.
