Dehumidified air passes through heating coils causing it to warm
(this unit is not a cooler). This is not a malfunction.
Check to see if the temperature/humidity is low.
Low room temperature/humidity reduces dehumidifying effectiveness.
Confirm the current humidity reading (in winter, the air is cooler reducing
the amount of water collected). This is not a malfunction.
Check to see if the power cord is correctly plugged.
→
Plug the power cord properly into the power socket.
Check to see if anything is blocking the air intake or outlet.
→
Remove the obstruction.
Check to see if the pre-filter is clogged.

The unit may sometimes stop operation after just a short
amount of time as a result of conditions such as the room
temperature and humidity.

Refrain from opening doors/windows during operation.
Check to see if steam producing appliances such as kerosene
heaters are on in the vicinity.
Hygrometer readings differ from place to place even if in the
same room. Use the unit humidity reading as an estimate.
