Maintenance

Regular maintenance is required for efficient operation. Clean the air filter frequently to avoid dust buildup. Use a soft, dry cloth or a cloth dipped in neutral detergent to clean the unit surface. Do not use volatile liquids like gasoline or thinner.

Troubleshooting

If the unit fails to operate, check for power failure, blown fuses, or active timer settings. Insufficient airflow may be caused by dirty filters or obstructed vents. The unit displays error codes (e.g., E1, E2, E3) to indicate specific faults like sensor issues or communication errors.

Practical help

Common problems

Appliance does not operate

Check for power failure, loose connections, or if the TIMER-ON function is active.

Insufficient airflow

Check for dirty air filters or obstructed air conditioner intakes and outlets.

Remote control does not respond

Ensure the remote is close enough to the indoor unit, replace batteries, or remove obstacles between the remote and the signal receiver.

Strange noise during operation

Expansion or contraction of the front panel due to temperature changes is normal. If the noise is persistent, check for backflow of liquid in the refrigerant circulation.

Before use

  • Ensure power supply voltage complies with the rating plate specifications.
  • Verify all electrical connections are secure.
  • Confirm the drainage pipe is smooth and unobstructed.
  • Ensure refrigerant valves are fully open.
  • Check that no foreign objects or tools are left inside the unit.
  • Complete installation of the indoor unit air inlet grille and panel.
