NSTALLING THE INDOOR UNIT
Placing the Indoor Unit in Position
Once you have checked that there are no leaks in the system, you can insulate
the piping, hose and cables and place the indoor unit on the installation plate.
1
To avoid condensation problems, place heat-resistant polyethylene foam
separately around each refrigerant pipe in the lower part of the indoor unit.
2
Wind insulating tape around the pipes, assembly cable and drain hose.
3
Place the resulting bundle carefully in the lower part of the indoor unit,
making sure that it does not jut out from the rear of the indoor unit.
4
Hook the indoor unit on to the installation plate and move the unit to the right
and left until you are sure that it is securely in place.
5
Finish wrapping vinyl tape around the rest of the piping leading to the
outdoor unit.
6
Using clamps (optionally supplied), attach the piping to the wall wherever
possible.

Assigning Address to Indoor Unit
Before installing the indoor unit, assign an address to the indoor unit
according to the air conditioning system plan.
1
The address of the indoor unit is assigned by adjusting MAIN(SW02).
❋
You don’t have to assign the MAIN address when installing one
indoor unit for one outdoor unit.
2
The MAIN address is for communication between the indoor unit and the outdoor
unit. Therefore, you must set it to operate the air conditioner properly.
3
It is required to set the RMC address if you install the wired remote
controller and/or the centralized controller.
4
If you install optional accessories such as the wired remote controller,
centralized controller, etc. see an appropriate installation manual.
5
Refer to the outdoor unit installation manual for the details.
