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.

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, depending on the model.
Move to left or right
Step 4.2. Connect drain hose and refrigerant
piping (refer to Refrigerant Piping Connection
section of this manual for instructions).
Step 4.3. Keep pipe connection point exposed to
perform the leak test (refer to Electrical Checks
and Leak Checks section of this manual).
Step 4.4. After the leak test, wrap the connection
point with insulation tape.
Step 4.5. Remove the bracket or wedge that is
propping with insulation tape.
Step 4.6. 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.
