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.
Replace the wire cover on the front of the unit, and the plastic
panel on the back.
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 piping through the
hole in the wall, proceed to Step 4.
Otherwise, double-check that the ends of the refrigerant pipes
are sealed to prevent dirt or foreign materials from entering the
pipes.
Slowly pass the wrapped bundle of refrigerant pipes, drain
hose, and signal wire through the hole in the wall.
Hook the top of the indoor unit on the upper hook of the
mounting plate.
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 bottom half of the unit.
Keep pushing down until the unit snaps onto the hooks along
the bottom of the mounting plate.
Again, check that the unit is firmly mounted by applying slight
pressure to the left and the right-hand sides of the unit.
ABOUT WIRING
THE WIRING CONNECTION PROCESS MAY DIFFER SLIGHTLY
BETWEEN UNITS.
DO NOT MIX UP LIVE AND NULL WIRES
This is dangerous, and can cause the air conditioning unit to
malfunction.
Step 7: Wrap piping 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.
Bundle the drain hose, refrigerant pipes, and signal cable
according to Fig. 3.12 .
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.
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).
While bundling these items together, do not intertwine or cross
the signal cable with any other wiring.
Using adhesive vinyl tape, attach the drain hose to the underside
of the refrigerant pipes.
Using insulation tape, wrap the signal wire, refrigerant pipes,
and drain hose tightly together. Double-check that all items are
bundled in accordance with Fig. 3.12 .
