4.1.4. Choose the right cable size
The size of the power supply cable, communication cable, fuse, and
switch needed is determined by the maximum current of the unit. The
maximum current is indicated on the dataplate located on the side panel
of the unit. Refer to this dataplate to choose the right cable, fuse, or
switch.
4.1.5. Take note of fuse specifications
The air conditioner's circuit board (PCB) is designed with a fuse to
provide overcurrent protection. The specifications of the fuse are printed
on the circuit board, such as: T3.15A/250VAC, T5A/250VAC, etc.

unit. This will reveal the terminal block.
All wiring must be performed strictly in accordance with the wiring
diagram located on the inside of the indoor units wire cover.
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.
5
Feed the signal wire through this slot, from the back of the unit to
the front.
6
Facing the front of the unit, match the wire colors with the labels on
the terminal block, connect the u-lug and and firmly screw each wire
to its corresp onding terminal.
DO NOT MIX UP LIVE AND NEUTRAL 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 communication 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 models.
Step 7: Wrap piping and cables
Before passing the piping, drain hose, and the communication 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 communication cable
according to Fig. 4.10.
