Maintenance method:

1. If the filter screen is too dirty or there are foreign matters on the surface of the two filters, resulting in mildew, clean the filter screen or the two filters and keep them clean.

2. Foreign matters generated from raw materials of new machines and new parts will disperse automatically a few days after startup.

3. Non dehumidification with gas and foreign matters may be caused by refrigerant leakage.

4. Burnt smell may be caused by the burning of the electric control system. Check the electric control box to see the cause of the fault.
