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 unit 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 hole 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 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.
3.
Inter-unit wiring
1) Remove the upper front panel, then remove 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.

When stripping off the ends of inter-unit
wire in advance, cover the ends with
insulating tape to make it easier to pass
