1. Open front panel of the indoor unit.
NOTE ABOUT WIRING
2. Using a screwdriver, open the wire box cover
on the right side of the unit. This will reveal
the terminal block.
THE WIRING CONNECTION PROCESS MAY
DIFFER SLIGHTLY BETWEEN UNITS AND
REGIONS.
Step 7: Wrap piping and cables
Terminal block
Wire cover
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(Not applicable in
North America).

Cable clamp
1. Bundle the drain hose, refrigerant pipes, and
signal cable as shown below:

3. Unscrew the cable clamp below the terminal
block and place it to the side.
4. Facing the back of the unit, remove the plastic
panel on the bottom left-hand side.
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.
5. Feed the signal wire through this slot, from
the back of the unit to the front.
6. Facing the front of the unit, connect the wire
according to the indoor unit’s wiring diagram,
connect the u-lug and firmly screw each wire
to its corresponding terminal.
CAUTION
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.
DO NOT MIX UP LIVE AND NULL WIRES
This is dangerous, and can cause the air
conditioning unit to malfunction.
3. Using insulation tape, wrap the signal wire,
refrigerant pipes, and drain hose tightly
together. Double-check that all items are
bundled.

Installation
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.
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).
