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.
