INDOOR UNIT INSTALLATION

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 overow, which
may lead to re or water damage.
DRAIN HOSE MUST BE ON BOTTOM
The signal cable must be protected by conduit
before being pushed through the wall hole.
SIGNAL CABLE PROTECTION
2. Using vinyl tape, attach the drain hose to the
underside of the refrigerant pipes.
3. Using insulation tape, wrap the refrigerant pipes
and drain hose tightly together. Double-check that
all items are bundled in accordance with Fig. 4.8.
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 (refer
to Electrical Checks and Leak Checks section of this
manual).
DO NOT WRAP ENDS OF PIPING
Step 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 material from entering the pipes.
3. Slowly pass the wrapped bundle of refrigerant
pipes and drain hose 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 rmly on mounting plate
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 rmly 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. 4.9 for an
example.
3. Connect drain hose and refrigerant piping (refer
to Refrigerant Piping Connection section of this
manual for instructions).
4. Keep piping connections exposed to perform the
leak test (refer to Electrical Checks and Leak Checks
section of this manual).
5. After the leak test, wrap the piping connection
points with insulation tape.
6. Remove wedge 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
