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 hole cover in the feed-through hole to prevent
possible heat, electrical shock, or fi re.
•
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 embedded pipe into the hole.
3) Insert a wall hole cover into wall pipe.
4) After completing refrigerant piping, wiring, and drain piping, caulk pipe
hole gap with putty.
