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 plate 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 3-1/8 inch (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.
4) After completing refrigerant piping, wiring, and drain piping, caulk pipe hole
gap with putty.
3.
Inter-unit wiring
1) Open the front panel, then open the service lid.
2) Pass the inter-unit wire from the outdoor unit through the feed-
through wall hole and then through the back of the indoor unit. Pull
them through the front side. Bend the ends of tie wires upward for
easier work in advance. (If the inter-unit wire ends are to be stripped
first, bundle wire ends with adhesive tape.)
3) Press the bottom frame of the indoor unit with both hands to set it on
the mounting plate hooks. Make sure the wires do not catch on the
edge of the indoor unit.
* The removed pipe port cover can be
kept in the mounting plate pocket.
