Indoor Unit Wiring
1. Prepare the cable for connection
a. Using wire strippers, strip the rubber jacket
from both ends of signal cable to reveal
about 15cm (5.9”) of the wires inside.
b.
Strip the insulation from the ends of the wires.
c. Using wire crimper, crimp the u-lugs to the
ends of the wires.
2. Open the front panel of the indoor unit. Using
a screwdriver, remove the cover of the electric
control box on your indoor unit.
3. Thread the power cable and the signal cable
through the wire outlet.

4. Connect the u-lugs to the terminals.
Match the wire colors/labels with the labels on
the terminal block, and firmly screw the u-lug
of each wire to its corresponding terminal.
Refer to the Serial Number and Wiring Diagram
located on the cover of the electric control box.

NOTE: While connecting the wires, please
strictly follow the wiring diagram (found inside
the electrical box cover).
2. Remove the electric cover of the outdoor unit.
If there is no cover on the outdoor unit,
disassemble the bolts from the maintenance
board and remove the protection board.

CAUTION
• While connecting the wires, please strictly follow the wiring diagram.
• The refrigerant circuit can become very hot. Keep the interconnection cable away from
the copper tube.
5. Clamp down cable with the designated cable clamp to secure it in place. The cable should not be
loose, and should not pull on the u-lugs.
6. Reinstall the electric box cover and the front panel of the indoor unit.
