Indoor Unit Installation
3) Shape the refrigerant pipe along the pipe path marking on the
mounting plate.
4) Pass drain hose and refrigerant pipes through the wall hole,
then set the indoor unit on mounting plate hooks, using the
markings at the top of indoor unit as a guide.
5) Pull in the interconnecting wires.
6) Connect the inter-unit piping.
7)
Wrap the refrigerant pipes and drain hose together with insulation
tape as right figure, in case of setting the drain hose through the back
of the indoor unit.
8)
While exercising care so that the
interconnecting wires do not catch indoor
unit, press the bottom edge of indoor unit
with both hands until it is firmly caught by
the mounting plate hooks. Secure
indoor unit to the mounting plate with
screws (M3/16” × 1/2”L).
3-3. Wall Embedded Piping
Follow the instructions given under
1) Insert the drain hose to this
depth so it wont be pulled out
of the drain pipe.
4. Wiring.
1) Strip wire ends (9/16in).
2)
Match wire colours with
terminal numbers on indoor
and outdoor unit’s terminal
blocks and firmly screw wires
to the corresponding terminals.
3) Connect the earth wires to the corresponding terminals.
4) Pull wires to make sure that they are securely
latched up, then retain wires with wire retainer.
5)
In case of connecting to an adapter system. Run the remote control
cable and attach the S21 connector as the illustration above.
6) Shape the wires so that the service lid fits securely, then close service lid.
Wrap insulating tape around the bent portion
of refrigerant pipe.
Overlap at least half the width of the tape
with each turn.

1) Do not use spliced wires, stand wires, extension cords, or starbust
connections, as they may cause overheating, electrical shock, or fire. Follow

2) Do not use locally purchased electrical parts inside the product. (Do not
overload the circuit by adding drain pump or other electrical equipment to unit
terminals.) Doing so may cause electric shock or fire.
3) When carrying out wiring connection, take care not to pull at the conduit.
