•
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 2 m 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
4.2 mm). 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. 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)
OTHERS
•
The connection method of the air conditioner and the power cable and the interconnection method of each
independent element shall be subject to the wiring diagram affixed to the machine.
•
The model and rating value of the fuse shall be subject to the silkscreen on corresponding controller or fuse sleeve.
