•
Make sure that the wiring does not touch sharp edges.
•
Otherwise, the wiring may be damaged and serious accident and malfunction of the air handler may
result.
•
Do not connect the fan motor wiring from TB1-#2 to fan motor run capacitor for air handler model AP60.
Otherwise, serious accident and malfunction of the air handler may result.
There are three wiring from the control box for the fan motor.
• Wiring from "X2" terminal on PCB2 connects to "HI" terminal of fan motor.
• Wiring from "X4" terminal on PCB2 connects to "MED" terminal of fan motor.
• Wiring from TB1-#2 must be connected as shown above and depends on corresponding air handler model.
(Connection is different for air handler model AP60)
(1) Pass the fan motor wiring through the conduit hole for the fan motor wiring on the DX-Kit control box. (When
connecting the fan motor wiring from outside the control box, run through the conduit tube.)
(2) Route the three wirings for the fan motor inside the air handler by passing through the connecting hole on
the left side of the air handler.
(3) Use the cable holder to secure excess wiring.
