SPLIT 1X1 IX21D5
4.8 MOUNT INDOOR UNIT
If you installed new connective piping to the outdoor unit, do the following:
1. If you have already passed the refrigerant piping through the hole in the wall, proceed to Step 4.
2. Otherwise, double-check that the ends of the refrigerant pipes are sealed to prevent dirt or foreign
materials from entering the pipes.
3. Slowly pass the wrapped bundle of refrigerant pipes, drain hose, and signal wire through the hole in the
wall.
4. Hook the top of the indoor unit on the upper hook of the mounting plate.
5. Check that unit is hooked firmly on mounting by applying slight pressure to the left and right-hand sides
of the unit. The unit should not jiggle or shift.
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.
7. Again, check that the unit is firmly mounted by applying slight pressure to the left and the right-hand
sides of the unit.
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.
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.)
