Maintenance
Activities required before starting maintenance
Warning of electrical voltage
Do not touch the mains plug with wet or damp hands.
•
Hold onto the mains plug while pulling the power cable out
of the mains socket.
Cleaning the housing
Clean the housing with a soft, damp and lint-free cloth. Ensure
that no moisture enters the housing. Protect electrical
components from moisture. Do not use any aggressive cleaning
agents such as cleaning sprays, solvents, alcohol-based or
abrasive cleaners to dampen the cloth.
Cleaning the inside of the device
The air sucked in by the dehumidifier may contain dust and
other contaminants. This dust and dirt may collect at the water
outlet of the condensate collection tray or in the container of the
pump and clog it. To guarantee failure-free operation, the pump
and the dehumidifier should be cleaned at regular intervals to
remove any deposits.
Normal cleaning
Perform this activity at least every three months.
For normal cleaning it is sufficient to rinse the pump with clean
water, e.g. after dehumidification in a clean room, or by having
the pump (12) pump clean water as follows:
ü
The connected dehumidifier is switched off.
1. Provide a container with clean water.
2. Remove the condensation drain hose from the dehumidifier
and pour clean water into the hose end.
3. Switch on the condensate pump and operate it until only
clean water is pumped by the pump (12).
Note
Clean the pump thoroughly while it is not pumping any
water.
Thorough cleaning
Perform this activity at least once a year.
1. Remove the hose lines at the discharge hose (8) and feed
hose (10) connections.
2. Clean the hose lines and connections at the pump and
remove any dirt.
3. Remove the housing cover (1), see chapter Assembly and
installation.
4. Remove the white and black connection plug.
5. Loosen the two nuts holding the pump on the housing wall.
If applicable, pull the hose out of the pump's container.
