DRILLING 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) Drill 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.
