Opening the filter housing and cleaning the different filters (Fig. E-G)
Unscrew the branch valve (12) and the attachment elements. Pull the clamps on both sides of the bottom strainer
casing (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
filters (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 (Fig. 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 (Fig. J)
Note!
A safety switch prevents switching on the UVC lamp as long as the UVC water housing is removed.
The UVC water housing (J, 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 (Fig. P - 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.
Assembly of the unit (Fig. S-V)
Bolt the pump (28) to the UVC water housing (26) using the union nut. Insert fine foam filter (22) in the bottom strainer
casing (2), place the bio surface elements (23) and the gravel bag (24) in the bottom strainer casing (2). Insert the UVC
clarifying unit including the pump (20). Insert the foam filter (3). Attach the top strainer casing (1) and press it onto the
bottom strainer casing (2) until the clamps engage in the bottom strainer casing. Important: Guide the connection
cable (7) through the cable opening at the bottom strainer casing (2) and clip with the cable kink protection in the
bottom strainer casing (U, 37).
