Electric Safety Requirements

Warning
The air conditioner shall be installed according to the local wiring specifications.
Wiring work must be completed by qualified electricians.
All wiring work must comply with electrical safety specifications.
The air conditioner must be well grounded. Specifically, the main switch of the air
conditioner must have a reliable grounding cable.
Before contacting wiring devices, cut off all the power supplies.
The user MAY NOT disassemble or repair the air conditioner. Doing so can be dangerous.
In the event of a fault, immediately cut off the power and contact your local dealer or
technical support.
A separate power supply that meets the rated parameter values must be provided for the
air conditioner.
The fixed wiring to which the air conditioner is connected must be equipped with a power
cut-off device that meets the wiring requirements.
To avoid danger, a damaged power cable must be replaced by professionals from the
maintenance department or a similar department of the manufacturer.
The air conditioner's circuit board (PCB) is designed with a fuse to provide overcurrent
protection.
The specifications of the fuse are printed on the circuit board.
NOTE: For the units with R32 refrigerant , only the blast-proof ceramic fuse can be used.
Caution
Always ground the main power switch.
Do not use a damaged power cable and replace it if it is damaged.
When the air conditioner is used for the first time or is in a power-off state for a long
time, it needs to be connected to the power supply and warmed up for at least 12 hours
before use.
