NOTE ABOUT WIRING
THE WIRING CONNECTION PROCESS MAY
DIFFER SLIGHTLY BETWEEN UNITS AND
REGIONS.
Step 7: Wrappping and cables
Before passing the piping, drain hose, and the
signal cable through the wall hole, you must
bundle them together to save space, protect
them, and insulate them(This may not applicable
for some locations in US).
Bundle the drain hose, refrigerant pipes, and
1.
signal cable as shown below:
Indoor Unit
Signal wire Drain hose
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.
2. Using adhesive vinyl tape, attach the drain
hose to the underside of the refrigerant pipes.
Using insulation tape, wrap the signal wire,
3.
refrigerant pipes, and drain hose tightly
together. Double-check that all items are
bundled.
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 (refer to Electrical Checks

Step 8: Mount indoor unit
If you installed new connective piping
to the outdoor unit, do the following:
If you have already passed the refrigerant
1.
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.
Using even pressure, push down on the
6.
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.
