If refrigerant piping is already embedded in the wall,
do the following:
Hook the top of the indoor unit on the upper hook of the
mounting plate.
Use a bracket or wedge to prop up the unit, giving you
enough room to connect the refrigerant piping, signal cable,
and drain hose.
Connect drain hose and refrigerant piping (refer to
Refrigerant Piping Connection section of this manual for
instructions).
Keep pipe connection point exposed to perform the leak
test (refer to Electrical Checks and Leak Checks section of
this manual).
After the leak test, wrap the connection point with
insulation tape.
Remove the bracket or wedge that is propping up the unit.
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.
Move to left or right

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 (1.18-1.96in), depending on the model.
