ELECTRICAL CONNECTION
WARNING! Improper wiring between the inside units and the outside unit can cause serious
damage to the system, and the risk of personal injury or fire. Use caution when
connecting the wiring to insure that the wires are connected properly.
DO NOT USE THERMOSTAT WIRE TO CONNECT OUTDOOR TO INDOOR UNIT!
1. Wiring of the Single-Core cable. See Figure 19.
a. Strip the insulating layer at the end of the cable about 0.98
” off with a wire striper.
b. Loose the screw off on the wiring board of the air conditioning unit.
c. Shape with the pliers at the end of the cable to a circle matching with the size of the screw.
d. Let the screw go through the circle of the cable and then fix it on the wiring board.
2. Wiring of the Multi-Core cable. See Figure 19.
a. Strip the insulating layer at the end of the cable about 3.9
” off with a wire striper and screw up.
b. Loosen the screw off on the wiring board of the air conditioning unit.
c. Fix a wiring terminal matching with the size of the screw to the end of the multi-core cable with
the pliers.
d. Let the screw go through the terminal of the multi-core cable and then fix it on the wiring board.

CAUTION!
a. If the power cord or the signal line is damaged, they must be replaced with the dedicated one.
b. Prior to the wiring, please check the voltage marked on the product label and then wiring by
following the wiring diagram.
c. The dedicated power cord must be used for the air conditioning unit and the electrical leakage
protection switch and air switch must be installed in case of the overload condition.
d. The air conditioning unit must be earthed to prevent the hazard caused by the failed insulation.
e. During the wiring, the wiring terminal or the single-core wire must be used; the direct wiring
between the multi-core cable and wiring board would cause fire.
f.
All wiring should be done strictly in accordance with the wiring diagram; otherwise the improper
wiring would cause the air conditioning unit running abnormally or damage.
g. Do not let the electric wires touch the refrigerant pipe, the compressor, the fan or other moving
parts.
h. Do not modify the wiring inside the indoor unit randomly; otherwise the manufacturer won
’t assume
any responsibility for the damage or abnormal running of the unit.
