casing (1) and press it onto the bottom strainer casing (2) until the clamps engage in the bottom strainer casing. Im-
portant: Lead the connection cable (7) through the cable opening in the bottom strainer casing (2) and route the cable
such that pinching is avoided.

Switching on / switching off (Figure F)
Attention! Dangerous electrical voltage.
If cables or components are defective, unit components and pond water can carry dangerous electrical
voltage.
Possible consequences: Death or severe injury from electrocution.
Protective measures: Disconnect the power plug (19) prior to reaching into the water and commencing
work.
Never operate the unit without water or without pump filter!
In the event of overheating, a fitted temperature monitor switches the UVC lamp off automatically, the lamp automati-
cally switches on again once it has cooled down.
The unit switches on automatically when power connection is established.

Cleaning and maintenance, changing the UVC lamp (Figures G-V)
Attention! Dangerous electrical voltage.
If cables or components are defective, unit components and pond water can carry dangerous electrical
voltage.
Possible consequences: Death or severe injury from electrocution.
Protective measures: Disconnect the power plug (Figure F, 19) prior to reaching into the water and
commencing work.
Open the filter housing (Figure G-I):
Unscrew the stepped hose adapter (16) prior to removing the bend (15). 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 UVC clarifying unit including pump
(20), foam filters (3, 22), bio surface elements (23) and gravel bags (24). When the aeration stone (25) is connected,
put it to the side. 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 gravel bags (24) under running water. Do not use chemi-
cal cleaning agents as they would kill the micro-organisms in the different filter media. At the beginning, this entails a
reduced filter capacity.
Clean the pump (Figure J, K)
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.
Cleaning the UVC clarifying unit (Figures L, M)
Note: A safety switch prevents switching on the UVC lamp as long as the housing is removed.
In the UVC water housing (26), the unit head (31) is fastened by means of a bayonet closure. Press on the engage-
ment lug (30) at the unit head (31), turn the unit head (31) counter-clockwise and carefully pull it out of the UVC water
housing (26). 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.
Replacing the UVC lamp (Figures M-Q)
For an optimum filter performance, we recommend to replace the UVC lamp after approx. 8000 operating hours.
Important: Only use lamps the identification and capacity data of which correspond to the information on the type
plate.
