WARNING
DO NOT MIX UP LIVE AND NULL WIRES
This is dangerous, and can cause the air conditioning
unit to malfunction.
7.
After checking to make sure every connection is
secure, use the cable clamp to fasten the signal
cable to the unit. Screw the cable clamp down
tightly.
8.
Replace the wire cover on the front of the unit, and
the plastic panel on the back.
NOTE ABOUT WIRING
THE WIRING CONNECTION PROCESS MAY DIFFER
SLIGHTLY BETWEEN UNITS AND REGIONS.
Step 7: Wrapping 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.
1. Bundle the drain hose, refrigerant pipes, and signal
cable as shown below:
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.
3. Using insulation tape, wrap the signal wire,
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 and Leak Checks section of this
manual).
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 provent 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 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 anf the right-
hand sides of the unit.
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.
