Maintenance and service
Filter replacement
The dehumidifier's filter must be replaced regularly, at least once a year. If the air filter is extremely
dirty it must be replaced more often.
1. Disconnect the power from the dehumidifier.
2. Turn the button on the filter cover anti-clockwise and open the cover. Pull out the dirty
filter from the machine and slide in the new one. Close the cover and turn the button
clockwise to lock it.
3. Reconnect the power to the dehumidifier.
As a routine, also check the outlet at the outside of the foundation wall after replacing the filter,
ensure that it is always unobstructed so that air can flow out freely.
Checking rotor operation
In event of repeated overheating when the heat protection has tripped, check that the rotor rotates
according to the following instructions.
As this inspection must be carried out with the dehumidifier powered, the utmost
caution must be observed. Do not insert your fingers or any tools into the machine!
1. Because the dehumidifier is connected to the power supply, remove the wet air hose from
the machine using tools.
2. Using a torch, look into the machine through the connector, the pipe on which the hose was
installed, and verify that the rotor rotates slowly. (The rotor's interior can be liked to a
honeycomb structure)
3. Reinstall the wet air hose. If the rotor does not rotate, contact the dealer for repair.
