Maintenance and cleaning (M-S)
Attention! Dangerous electrical voltage.
Possible consequences: Death or severe injury.
Protective measures: Disconnect the power plug (Figure L, 19) prior to reaching into the water and com-
mencing work.
Only clean the unit when necessary. Clean the filter system immediately when the float switch in the water level indica-
tor (20) has reached its maximum raised position. Switch off the pump and secure against unintentional switching on
again. Remove the four cap nuts from the cover (figure E, 11), then remove the cover from the container.
Cleaning the water level indicator (M)
Turn the water level indicator (2) and pull it out of the inner cover. Remove the plug (25) and the float switch (24) out of
the housing (23) of the water level indicator and clean using clear water. Reassemble in the reverse order such that the
float switch (24) can move freely in the housing (23).
Cleaning the container (N)
Open the slide valve (22) of the sludge drain and wait until the pond water has drained. Fit a fresh water hose (26) to
the spray system (27) and supply fresh water. Once the container is rinsed inside and the water has drained, firmly
close the slide valve (27) again and fill the container with fresh water up to the drain level. Upon completion of the
cleaning work, switch the pump on and check the unit for leaks. Close the container with the cover and secure with the
four cap nuts.
Cleaning and replacing the UVC lamp (O-S)
For an optimum filter performance, we recommend to replace the UVC lamp after approx. 8000 operating hours.
Dismantling the unit head (O)
Loosen the coupling (28) of the power connection cable for the unit head (31) concerned. In the housing (30), the unit
head (31) is fastened by means of a bayonet closure. Press on the engagement lug (29) at the housing (30), turn the
unit head (31) counter-clockwise and carefully pull it out of the housing (30). Note: A safety switch prevents switching
on the UVC lamp when the unit head (31) is removed.
Cleaning the quartz glass (P)
Check the quartz glass (33) for damage and clean its outer face with a moist cloth.
Note: Condensate could collect in the quartz glass because of the vertical installation position of the UVC. Remove the
quartz glass and remove condensate. Do not allow condensate to enter the unit head!
Changing the UVC lamp (Q, R)
Important! Only use lamps the identification and capacity data of which correspond to the information on the type
plate.
Note: Condensate could collect in the quartz glass because of the vertical installation position of the UVC. Remove the
quartz glass and remove condensate. Do not allow condensate to enter the unit head!
Unscrew the clamping screw (32) counter-clockwise. Pull off the quartz glass (33) including the O ring (34) by exerting
a slight rotary movement. Pull out the UVC lamp (35) and replace. Check the quartz glass (33) and the O ring (34) for
damage. Insert the quartz glass (33) including the O ring (34) against the stop in the unit head (31). Tighten the clamp-
ing screw (32) clockwise up to the stop.
Unit reassemby (O, R, S)
Check the O ring (36) at the unit head (31) for damage. Carefully push the unit head (31) into the housing (30) up to
the stop while applying slight pressure. While doing so, slightly turn the unit head (31) to ensure that the tenons and
the grooves of the bayonet closure intermesh. Turn the unit head (31) clockwise up to the stop. Connect the coupling
(28) to the power supply cable. Important: Tightly screw-connect the plug and the socket of the coupling (28) to ensure
that the contacts are moisture protected. Install the couplings (28) as shown in picture S. Fit the cover and secure
cover with four cap nuts.

Wear parts

The UVC lamp is a wearing part and does not fall under the warranty.
Storage/Over-wintering
Put the system out of operation at water temperatures below 8 °C or, at the latest, when freezing temperatures are to
be expected. Drain and thoroughly clean the system, check for damage. Drain all hoses, pipework and connections as
far as possible, leave the slide valve at the container open. Cover the container so that no rain water can enter.
Disposal
Dispose of the unit in accordance with the national legal regulations. The UVC lamp needs special disposal. Ask your
specialist dealer.
