2.

Boring a wall hole and installing wall embedded pipe.

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

ded 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.
