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.

2.
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.
1) Drill a feed-through hole with a
3-1/8 inch (80mm) diameter
through the wall at a downward angle 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
the pipe hole gap with putty.
3.
Installing the indoor unit
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
mounting plate hooks,
using 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 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
mounting plate hooks. Make sure that the wires do not catch on the edge of the indoor unit.
