8.3 Maintenance and Repair

If the dehumidifier does not work properly, contact a 
dealer or our customer service. The contact details can 
be found in chapter 1.2 Customer Service. All protective 
and safety equipment must be reinstalled immediately 
after repair and maintenance work has been completed.

Maintenance of the water pump

The pump is equipped with a quick connection con-
struction. When maintenance is required, the conden-
sate hose, float switch ports, and power cord to the 
pump can be easily disconnected. The pump can be re-
moved from the container using a flat screwdriver. The 
dehumidifier is equipped with an integrated condensate 
pump, which pumps the condensate from the dehumidi-
fier into the desired drain. This pump requires routine 
maintenance.
