Maintenance and cleaning

T I P
Recommendation regarding cleaning:
• Clean the unit as required but at least twice a year.
• When cleaning the pump, pay particular attention to the cleaning of the impeller unit and pump housing.
• Clean the inspection window with cotton swabs.
T I P
Do not use chemical cleaning agents. Chemical cleaning agents kill the dirt-consuming microorganisms in the
filter media and so reduce the filter performance.
Opening the filter housing and cleaning the different filters
 E, F, G
Unscrew the branch valve (12) and the attachment elements. Pull the clamps on both sides of the bottom strainer cas-
ing (2) to the side and lift off the top strainer casing (1). Remove the foam filter (3) and the UVC clarifying unit including
pump (20), and the fine foam filters (22), bio surface elements (23) and the gravel bag (24).
Clean the bottom strainer casing (2) and the top strainer casing (1) with clear water using a brush. Wash out foam fil-
ters (3, 22), bio-surface elements (23) and the gravel bag (24) under running water. Do not use chemical cleaning
agents as they would kill the micro-organisms in the different filter media. At the beginning, this entails a reduced filter
capacity.
Cleaning the pump
 H, I
Unscrew pump (28) from the UVC water housing (26). Unscrew the pump lid (27) counter-clockwise (bayonet closure)
and remove rotor (29). Clean all components using clean water and a brush. After cleaning the pump, reassemble in
the reverse order.
Opening and cleaning the UVC water housing
T I P
For safety reasons the UVC lamp can only be switched on when the unit head has been correctly fitted into the
casing.
 J
The UVC water housing (26) is fastened to the unit head (31) by means of a bayonet closure. Press on the engage-
ment lug (30) at the unit head (31), turn the UVC water housing (26) counter-clockwise and carefully pull it off the unit
head (31). Clean the UVC water housing (26) under running water. Check the quartz glass (33) for damage and clean
its outer face with a moist cloth.
Note: For an optimum filter performance, we recommend to replace the UVC lamp after approx. 8000 operating hours.
Refer to 'Replace UVC lamp'.
Closing the UVC water housing
 P, Q, R
Check the O ring (37) at the unit head (31) for damage. Place the O ring (37) on the recess at the unit head (31), then
carefully push the UVC water housing (26) on the unit head (31) by applying medium pressure. While doing so, slightly
turn the UVC water housing (26) to ensure that the tenons (39) and the grooves (40) of the bayonet closure intermesh.
Turn the UVC water housing (26) clockwise against the stop and allow to engage.
