ELECTRICAL CONNECTION REQUIREMENTS
Electrical safety standards must be met when installing the unit.
Use a power supply circuit and circuit breaker that comply with local safety regulations.
Make sure that the power supply matches the requirements of the air conditioner. An unstable power supply or incorrect
wiring may result in a fault. Install suitable power cables before switching on the air conditioner.
Correctly connect the live, neutral and earth wires to the power outlet.
Disconnect the power supply before carrying out any work on the electrical circuit or carrying out any safety work. For
models with a plug, make sure the plug is easily accessible after installation.
Do not connect the power before installation is complete.
Do not use the appliance if the power cable or plug are damaged. If the power cable is damaged it must be replaced by
the manufacturer, retailer or other qualified person to avoid a hazard.
Since the temperature of the cooling circuit is high, keep the interconnecting cable away from the copper pipe.
The unit must be installed in accordance with national wiring regulations.
Installation must only be performed by trained individuals in accordance with regulations.
The unit is charged with a slightly inflammable refrigerant, R32. Improper handling of this gas may
expose people and materials to serious damage. More details on this refrigerant are given at the beginning of this manual.
REQUIREMENTS FOR OPERATIONS AT HEIGHT
• When carrying out installation at 2m or higher above the base level, safety belts must be worn and ropes of sufficient
strength be securely fastened to the outdoor unit, to prevent falling that could cause personal injury or death as well
as property loss.
GROUNDING REQUIREMENTS
• The air conditioner is the class I electrical appliance and must ensure a reliable grounding.
• Do not connect the grounding wire to a gas pipe, water pipe, lightning rod, telephone line, or a circuit poorly grounded
to the earth.
• The grounding wire is specially designed and shall not be used for other purpose, nor shall it be fastened with a
common tapping screw.
• Interconnection cord diameter should be recommended as per instruction manual, and with type O terminal that meet
local standards (internal diameter of type O terminal needs to match the screw size of the unit, no more than 4.2mm).
After installation, check the screws whether have been fixed effectively, and there is no risk of loosening.
• An all-pole isolating switch with a minimum contact gap of 3mm in each pole must be connected to the fixed cable.
• Insert a power switch with sufficient power and observe the following table. The air switch must include a magnetic
and thermal function to protect against short circuits and overloads. (Attention: Do not use only the fuse to protect
the circuit)
