2. Open front panel of the indoor unit.
3. Using a screwdriver, open the wire box cover on the right side of the
unit. This will reveal the terminal block.
The Wiring Diagram is located on the
inside of the indoor unit's wire cover.
Fig. 16.
WARNING
ALL WIRING MUST BE PERFORMED STRICTLY IN ACCORDANCE
WITH THE WIRING DIAGRAM LOCATED ON THE INSIDE OF THE
INDOOR UNIT'S WIRE COVER.
4. Unscrew the cable clamp below the terminal block and place it to
the side.
5. Facing the back of the unit, remove the plastic panel on the bottom
left-hand side.
6. Feed the signal wire through this slot, from the back of the unit to
the front.
7. Facing the front of the unit, match the wire colours with the labels
on the terminal block, connect the u-lug and firmly screw each wire
to its corresponding terminal.
CAUTION
DO NOT MIX UP LIVE AND NEUTRAL WIRES
This is dangerous and will cause the air conditioning unit to malfunction.
8. After checking ensure every connection is secure, use the cable
clamp to fasten the signal cable to the unit. Screw the cable clamp

Step 7: Wrap piping and cables

Before passing the piping, drain hose and 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 according
to Fig. 17.
Indoor Unit
Signal wire Drain hose
Fig. 17.
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 wiring 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
in accordance with Fig. 17.
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 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.
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 firmly mounted by applying slight
pressure to the left and the right-hand sides of the unit.
