Maintenance
：

Regularly check whether the three-phase current of the power supply is balanced, whether the fuse of the power supply is intact, and strictly prevent phase loss operation and damage to the motor.

The normal operating temperature of this equipment should be below 43 ℃. When the equipment does not operate at the normal operating temperature, high voltage protection will occur and the unit operation will stop, which belongs to the system protection of the equipment, not a quality fault.

3. It is necessary to regularly check whether there is too much dust accumulation on the heat exchange fins of the outdoor unit. If so, timely dust accumulation should be carried out. Use a soft bristled brush to brush up and down along the direction of the fins. Be careful not to overwhelm the heat exchange fins and affect ventilation.

4. Clean the air filter every 15 days to avoid dust blocking and affecting ventilation.

Equipment refueling and refrigerant addition should be strictly controlled and operated by professional personnel to avoid damaging the machine.

8 When using, if the fan stops running, it must be stopped immediately for inspection and troubleshooting before continuing to use.
