CAUTION
If drainage water overflows from the indoor unit, cease all operation and contact your dealer.

contact your dealer.
1. If Issues Persist
If the issues continue even after checking the following, contact your
information ready:
(1) Unit Model Name
(2) Description of the Issue
2. No Operation
Check whether the SET TEMP is set to the desired temperature.
3. Not Cooling or Heating Properly
Check for obstruction of air flow at the outdoor or indoor units.

Check if there are too many heating sources in the room.
●
Check if the air filter is clogged with dust or other obstructions.
●
Check if doors or windows are open.

Check if the ambient temperature conditions are within the operation range.

4. The Following Are Not Abnormal:
Odor from Indoor Unit
●
Unpleasant odor diffuses from indoor unit after a long period of time. Clean the air filter and panels and
ensure that there is sufficient ventilation.
Sounds from Moving Parts
●
When starting or stopping the system, a sound might be made. However, this is likely due to thermal
deformation of plastic parts. If so, it is not abnormal.
Steam from Outdoor Heat Exchanger
●
During the defrosting operation, ice on the outdoor heat exchanger melts, resulting in steam.
Dew on Air Panel
●
When the cooling operation operates for an extended period of time under high humidity conditions, dew can
form on the air panel.
Refrigerant Flow Sound
●
While the system is starting or stopping, the sound of refrigerant flowing may be heard.
Filter Cleaning
Please replace or clean the filter regularly, as dust can gradually accumulate onto the surface of the filter
after a long period of time.
Follow these steps to properly replace the filter:
After removing the two manual bolts, take down the filter
cover and pull out the filter from the case, then insert the
new one into the case along the filter rail. Finish by fixing
the filter cover with manual bolts.
