3. Using insulation tape, wrap the signal wire, refrigerant
pipes, and drain hose tightly together. Double-check that
all items are bundled in accordance with the picture above.
NOTE:
• Drain hose must be on bottom
Make sure that the drain hose is at the bottom of the
bundle. Putting the drain hose at the top of the bundle
can cause the drain pan to overflow, which can lead to fire
or water damage.
• Do not intertwine signal cable with other wires
While bundling these items together, do not intertwine or
cross the signal cable with any other wiring
• Do not wrap ends of piping
When wrapping the bundle, keep the ends of the piping
unwrapped. You need to access them to test for leaks at
the end of the installation process.
3.8 Mount indoor unit
3.8.1 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 Prepare
refrigerant piping.
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.
3.8.2 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.
• 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.
30-50m m
(1.2-1.95in)
Move to left or right
2. Use the holder in the mounting plate to prop up the
unit, giving you enough room to connect the refrigerant
piping, signal cable, and drain hose.
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.
