Indoor Unit Installation
If refrigerant piping is already embedded in
the wall, do the following:
1.
Hook the top of the indoor unit on the upper
hook of the mounting plate.
2.
Use a bracket or wedge to prop up the unit,
giving you enough room to connect the
refrigerant piping, signal cable, and drain
hose. Refer to Fig. 3.11 for an example.

Move to left or right
30-50mm
(1.2-1.95in)
30-50mm
(1.2-1.95in)
3.
Connect drain hose and refrigerant piping
(refer to
Refrigerant Piping Connection
section of this manual for instructions).
4.
Keep pipe connection point exposed to
perform the leak test (refer to Electrical
Checks and Leak Checks
section of this
manual).
5.
After the leak test, wrap the connection point
with insulation tape.
6.
Remove the bracket or wedge that is propping
up the unit.
7.
Using even pressure, push down on the
bottom half of the unit. Keep pushing down
until the unit snaps onto the hooks along the
bottom of the mounting plate.
UNIT IS ADJUSTABLE
Keep in mind that the hooks on the mounting plate are smaller than the holes on the back of the
unit. If you find that you don’t have ample room to connect embedded pipes to the indoor unit, the
unit can be adjusted left or right by about 30-50mm (1.25-1.95in), depending on the model. (See
Fig. 3.12
.)
