SIGNAL WIRES
Outdoor unit
1 Remove the self-tapping screws (3 pcs) fixing the
electric box cover and take out the electric box.
2 Loosen the fixing screw of the power terminal board
and signal terminal board, then firmly fix the power
wire and signal wire on the terminal board with the
fixing screw.
3 Fix the connected wires with wire spacer and anchor
cable. The ground wire must be firmly connected.
4 Since the piping is likely to have condensate, the power wire and signal wire should
use insulation sleeve to avoid contacting the pipe. Install the electric cover.
