Troubleshooting
Trouble: The unit does not work
Reason:
- No power supply
- Water-full indicator illuminated
- Timer function is active
- Room temperature too low or too high
Solution:
- Power-on and turn on the unit
- Drain the internal water tank
- Cancel Timer function
- Use only in ambient temperatures between 7-35℃
Trouble: The unit does not seem to perform
Reason:
- In direct sunlight
- Windows or doors open. Large amount of people or a heat source in the room
- Filter is very dirty
- Air inlet or air outlet is blocked
- Room temperature is lower than setting temperature
Solution:
- Draw the curtains, UV affects RC
- Close windows and turn on another air conditioner
- Clean or change the air filter
- Clear out debris
- Change the setting temperature
Trouble: The unit loud
Reason: The unit is not put on flat surface
Solution: Put the unit on flat and hard surface
Trouble: Compressor does not work
Reason: Overheating protection is active
Solution:
- Check venting.
- Restart the unit after 5 minutes when compressor has cooled
Trouble: Remote control doesn’t work
Reason:
- Operating distance is too far.
- Control panel has not received the signal from remote control.
- The batteries are flat
Solution:
- Move remote control closer to the unit and make sure it aims at the air-outlet grille
- Replace the batteries
