Requirements for operations at raised height
Grounding Requirements
Electrical Safety Requirements
• When carrying out installation at 2m or higher above the base level, safety belts must be worn and ropes of
sufficient strength be securely fasten to the outdoor unit, to prevent falling that could cause personal injury or
death as well as property loss.
• 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.
• Be sure to use the rated voltage and air conditioners dedicated circuit for the power supply, and the power cord
diameter must meet the national requirements.
• When the maximum current of air conditioner is ≥16A, it must use the air switch or leakage protection switch
equipped with protection devices.
• The operating range is 90%-110% of the local rated voltage. But insufficient power supply malfunction, electrical
shock, or fire. If the voltage instability, proposed to increase the voltage regulator.
• The minimum clearance between the air conditioner and the combustibles is 1.5 m.
• The interconnection cord connect the indoor and outdoor units. You must first choose the right cable size
before preparing it for connection.
• Cable Types: Outdoor Power Cable: H07RN-F or H05RN-F;
Interconnection cord: H07RN-F or H05RN-F;
• Minimum Cross-Sectional Area of Power cable and interconnection cord.
• The size of the interconnection cord, power 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.
• Note: Core number of cable refer to the detailed wiring diagram adhered on the unit which you purchased.
