Indoor Unit Installation
1.
Installing the mounting plate
• The mounting plate should be installed on a wall which can support the weight of the indoor unit.
1) Temporarily secure the mounting plate to the wall, make sure that the panel is completely level, and mark the boring points
on the wall.
2) Secure the mounting plate to the wall with screws.

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 65/80mm 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.
