First pull out the heater's mains plug. Close the tap lever
on the intake side (IN) of the integrated double tap
connector, so that the filter empties itself.
As soon as the pump loudly sucks in air, close the tap lever
on the output side (OUT) of the integrated double tap
connector and pull the mains plug out of the socket.
Swing the locking clamp up-
wards and then remove the
double tap connector from
the pump head. Extract the
filter out of the cabinet by
using the recessed handles.
Attention:
Do not pull on the wet/
dry floater compartment.
Open all four EZ clips and
remove the pump head from
the filter.
In order to clean the pump
chamber, open the sealing
ring of the pump head by
turning it anticlockwise.
Take off the pump cover and
then remove the impeller and
shaft.
Thoroughly clean pump parts, impeller chamber and lubri-
cation channel with the EHEIM cleaning set (order no.
4009580.)
Carefully rinse off the shaft (risk of breakage!), then put
the impeller back together again and insert into proper
position.
Pay attention to the proper fit of the shaft bushings, pump
cover and sealing ring. Then lock the pump with the sealing
ring.

TIP:
If cleaning water should get
into the cover of the filter's
pump head, the cover can be
unscrewed and wiped dry
with a cloth.
