Step 4: Prepare refrigerant piping
The refrigerant piping is inside an insulating
sleeve attached to the back of the unit. You must
prepare the piping before passing it through the
hole in the wall. Refer to the Refrigerant Piping
Connection section of this manual for detailed
instructions on pipe flaring and flare torque
requirements, technique, etc.
NOTE ON PIPING ANGLE
Refrigerant piping can exit the indoor unit from
four different angles:
•
Left-hand side
•
Left rear
•
Right-hand side
•
Right rear
Refer to Fig. 4.4 for details.

CAUTION
Be extremely careful not to dent or damage the
piping while bending them away from the unit.
Any dents in the piping will affect the unit' s
performance.
If refrigerant piping is already embedded in
the wall, do the following:
Step 4.1:Hook the indoor unit on the mounting
plate:
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, depending
on the model. (See Fig.4.5)
