Indoor Unit Installation

2.

Boring a wall hole and installing wall embedded pipe.

• For walls containing metal frame or metal board, be sure to use a wall 

embedded pipe and wall cover in the feed-through hole to prevent possible 
heat, electrical shock, or fire.

• Be sure to caulk the gaps around the pipes with caulking material to prevent 

water leakage.
1) Bore a feed-through hole of 65mm in the wall so it has a down slope 

toward the outside.

2) Insert a wall pipe into the hole.
3) Insert a wall cover into wall pipe.
4) After completing refrigerant piping, wiring, and drain piping, caulk pipe hole 

gap with putty.

3.

Installing indoor unit.

3-1. Right-side, right-back, or right-bottom piping. 

1) Attach the drain hose to the underside of the refrigerant pipes with 

an adhesive vinyl tape.

2) Wrap the refrigerant pipes and drain hose together with an 

insulation tape.

3) Pass the drain hose and refrigerant pipes through the wall hole, 

then set the indoor unit on the mounting plate hooks by using the 

 markings at the top of the indoor unit as a guide.

4) Open the front panel, then open the service lid. 

(Refer to Installation tips.)

5) Pass the interconnecting wires from the outdoor unit through the 

feed-through wall hole and then through the back of the indoor 
unit. Pull them through the front side.  Bend the ends of tie wires 
upward for easier work in advance. (If the interconnecting wire 
ends are to be stripped first, bundle wire ends with adhesive 
tape.)

6) Press the bottom frame of the indoor unit with both hands to set 

it on the mounting plate hooks. Make sure the wires do not 
catch on the edge of the indoor unit.
