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 70mm 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.
3.
Installing inter-unit wiring.
1) Open the front panel and remove the service lid.
2) Pull out the inter-unit wiring from the back of the
indoor unit to the front. It is easier to pull out if
bending up the wire edge in advance.
3) To connect the inter-unit wiring after hooking the unit
onto the mounting plate, connect the inter-unit
wiring as shown in the figure at right.
