Insulation of the Pipe Joints
1. The refrigerant pipe should be insulated with appropriate insulating material and
plastic tape in order to prevent condensation and water leakage.
2. The joints of the indoor unit should be wrapped with insulating material. No gap is
allowed on the joint of the indoor unit, as shown below.
WARNING
1. If the power cord or the signal line are damaged, they must be replaced with the required
replacement part.
2. Prior to wiring, please check the voltage marked on the nameplate and carry out the wiring
following the wiring diagram.
3. 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 an overload condition.
4. The air conditioning unit must be grounded to prevent electrical shock hazards caused by
failed insulation.
5. All wiring should be done strictly in accordance with the wiring diagram, otherwise improper
wiring would cause abnormal operation or damage to the unit.
6. Do not let the electric wires touch the refrigerant pipe, the compressor, the fan or other
moving parts.
7. Do not modify the wiring inside the indoor unit, otherwise the manufacturer will not assume
any responsibility for damage or abnormal operation of the unit.
Wiring the Indoor Unit
1. Dismantle the cover of the electric box of the indoor unit.
2. Insert the power cord through the rubber ring.
3. Pull the 4-core cable through the hole of the chassis and the bottom of the appliance
upward, then connect the power line and the communication line from the outdoor unit to the
corresponding terminals N(1), 2, 3 and grounding terminal of the indoor unit. Wiring shall be
done properly as per the wiring diagram. (NOTE: Be sure the wiring terminals A/B/C/D and
piping ports A/B/C/D of the indoor unit match with that of the outdoor unit respectively).
