3-3. Attach the drain socket
As shown in Fig. 3-5, insert the drain socket into the U-shaped cutout.
4. Wiring
1. Passing the pump wires (Fig. 4-1)
(a) Route the 2 wires so that they pass through the raised part when the
maintenance cover is installed.
2. Connecting the pump wires to the control box of the indoor unit (Fig. 4-2)
(a) Insert the white connector into CN31 on the indoor P.C. board.
Since a connector has been inserted into both CNP and CN31 before
shipment, they must be removed.
(b) When wiring is complete, fasten the remaining cords with the band 3.
When fastening lead wires
Power wires and low-voltage wires are separated inside the control box to prevent noise. Lead wires from the Drain Water Lift-
Up Kit also need to be separated, so fasten them to the lead wires located inside the control box as described below.
• Since the yellow wire is used for power, its remaining portion must be fastened to the lead wires from the power terminal block.
• Since the clear wire is used for low voltage, its remaining portion must be fastened to the pipe sensor lead wire.
