Wiring Work
Communication wiring connections
• Communication wires connect through side of air handler.
• Use an approved connector at the cabinet of the unit to prevent pulling or shorting of control wires.
• Control wire must be rated for 600V minimum.
• Control wire insulation must be rated for temperatures up to 90°C.
ATTENTION
1. Insert the wires through the holes of the right side on the top casing and through the cable connectors.
2. Connect the communication wires to the F1/F2 connection terminal with compressed ring terminals.
3. Connect F3, F4 (for communication) when installing the wired remote control.
