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 drilling points
on the wall.
2)Secure the mounting plate to the wall with screws.

Drilling a wall hole and installing wall embedded pipe

WARNING
For metal frame or metal board walls, be sure to use a wall embedded pipe and wall hole cover in the feed-through hole to
prevent possible heat, electric shock, or fire.
• Be sure to caulk the gaps around the pipes with caulking material.
(to prevent condensation caused by intrusion of air from outside or within the wall)
1) Drill a feed-through hole with a 3-1/8 inch (80mm) diameter through the wall at
a downward angle toward the outside. (to prevent water leakage)
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 the pipe hole
gap with putty.

Installing the indoor unit

In the case of bending or curing refrigerant pipes, keep the following precautions in mind. Abnormal sound may be generated
if improper work is conducted.
• Do not strongly press the refrigerant pipes onto the bottom frame.
• Do not strongly press the refrigerant pipes on the front grille, either.
3-1. Right-side, right-back, or right-bottom piping
1) Attach the drain hose to the underside of the refrigerant
pipes with adhesive vinyl tape.
2) Wrap the refrigerant pipes and drain hose together with
an insulation tape.
3) Pass the drain hose and refrigerant pipes through the wall hole, then
position the indoor unit on the
markings at the top of the indoor unit as a guide.
4) Open the front panel, then open the service lid.
(Refer to "Service lid" on page 4.)
5) 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 cable 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.)
6) Press the bottom frame of the indoor unit with both hands until it is firmly caught by
the
indoor unit.
