Problem: The air conditioner is not running.
Reason:
- Power cut.
- On/off button is not turned on.
- The fuse is broken.
- Batteries of the remote have gone down.
- The time set to start running has not been reached.
- The remote control is not detecting.
- Light source is too close to the air conditioner.

- Wait for the power to be back.
- Turn on the air conditioner.
- Have the fuse changed.
- Change the batteries.
- Wait or cancel the setting.
- Change the batteries.
- Some light sources that are close to the air conditioner, may prevent its functioning creating a magnetic influence. Retry to use the remote control after disabling the light source. If the problem is solved, it would be useful to change the light source.
Problem: The air conditioner is blowing air, but cooling and heating performance is bad.
Reason:
- There is a mistake in temperature setting.
- Air filter is clogged with dust.
- Air inlet or outlet of the air conditioner is blocked.
- Door and windows are open.
Solution:
- Set appropriate temperature. See application methods
- Clean up dust filters.
- Clean the materials that cause blocking.
- Close the windows and the doors.
Problem: Air flow does not start immediately during heating.
Reason: The necessary temperature for heating has not been reached.
Solution: If air flow starts before the temperature rises, an undesired cooling effect will occur. In order to prevent this, air flow will start after necessary temperature is reached. This is not due to a malfunction of the air conditioner and it is not a failure.
Problem: The air conditioner is blowing air, but it does not cool.
Reason:
- Air inlet or outlet of the air conditioner is blocked.
- Compressor protection (3 min).
- There is a mistake in temperature setting.
Solution:
- Clean the materials that cause blocking and restart the air conditioner.
- Wait.
- Set appropriate temperature.
Problem: There is clicking sound coming from the air conditioner.
Reason: Temperature change.
Solution: Changes in temperature cause expansion and contraction of plastic materials. This is not due to a malfunction of the air conditioner and it is not a failure.
