■General Malfunction

The following actions might help you to resolve your A/C problem:

• Ensure the circuit breaker is on.
• Change the battery of your remote control and reset its power.
• Unplug the A/C's power and restart after 10 minutes.
• Open up the cover of the A/C and press an "emergency mode button".*
• In winter, the cause of the problem might be a frozen outdoor unit. In this case, please wait for a while until it gets defrosted.

Note: Your A/C information is required when you reach out to us: manufacturer, series model, and year of manufacture.

【In most cases, the details are printed at the bottom of the A/C】

A clogged drain hose on the outside unit may cause water leakage from your A/C. Shaking the drain hose gently and/or cleaning it could resolve the problem.

■Test Running

It is highly recommended to test your A/C as the seasons change. Especially in summer and winter, there is a high volume of A/C repair requests that makes it difficult to make a prompt appointment.

Note:

• When performing the test running in summer, set it to 18 Celsius and run it in “Cold” mode for 10 minutes to ensure that cold air comes out.
• Please clean the filter regularly, approximately once a month.

■Cleaning A/C Filters

1. Remove the filters and use a vacuum cleaner to get rid of dust.* 
2. Wash away the remaining buildup on the filters (Be gentle to the filters to avoid any damages on them).
3. Wipe off the water with a towel and let it dry in the shade. 
4. Set them back (No moisture left. It might cause mold and/or malfunction).

*How to clean the filters

Note: For internal cleaning of A/Cs, request it for a specialist if it’s necessary. Disassembling and cleaning further inside of the AC on your own may cause malfunction.
