7. Only connect the unit to an individual branch circuit outlet. Do not connect another
appliance to that outlet.
8. Make sure to properly ground the air conditioner.
9. Every wire must be firmly connected. Loose wiring can cause the terminal to overheat, resulting in
productmalfunction and possible fire.
10. Do not let wires touch or rest against refrigerant tubing, the compressor, or any moving parts
with in the unit.
11. lf the unit has an auxiliary electric heater, it must be installed at least 1 meter (40in) away
from any combustible materials.
12. To avoid getting an electric shock, never touch the electrical components soon after the
power supply has been turned off. After turning off the power, always wait 10 minutes or
more before you touch the electrical components.
WARNING
Before performing any electrical or wiring work, turn off the main power to the system.
Step 6: Connect signal cable
The signal cable enables communication between the indoor and outdoor units. You must first choose the
right cable size before preparing it for connection.
NOTE: The cable conection of the indoor unit had been finished in the factory.
Cable Types
• Indoor Power Cable (if applicable): H0SW-F or H05V2V2-F
• Outdoor Power Cable: H07RN-F
• Signal Cable: H07RN-F
Minimum Cross-Sectional Area of Power and Signal Cables (For reference)
Rated Current of Nominal Cross-Sectional
Appliance (A) Area (mm2)
> 3 and ≤ 6
> 6 and ≤ 10
> 10 and ≤ 16
> 16 and ≤ 25
> 25 and ≤ 32
> 32 and ≤ 40
CHOOSE THE RIGHT CABLE SIZE
The size of the power supply cable, signal cable, fuse, and switch needed is determined by the maximum
current of the unit. The maximum current is indicated on the nameplate located on the side panel of the
unit. Refer to this nameplate to choose the right cable, fuse, or switch.
WARNING
All wiring must performed strictly in accordance with the wiring diagram located on the back of
the indoor unit's front panel.
The wire connection between indoor unit and outdoor unit:
Align the two connectors and insert into each other until they are fixed with a clicking sound. The Y/G
wire should be connected individually. Secure the cable onto the control board with card clamp.
