Fitting the unit head
How to proceed:
 L
Position the O ring in front of the recess at the unit head.
– Ensure that the O ring is clean; replace if damaged.
Carefully push the unit head with cleaning rotor into the casing up to the stop while applying light pressure.
– Ensure that that the unit head is turned such that the markings on the unit head and casing are aligned.
Turn the unit head up to the stop.
– Ensure that the safety engagement catch engages.
Close the locking screw in the safety engagement catch.
– Rotational direction "Lock closed" symbol.
Cleaning the quartz glass
C A U T I O N
Quartz glass and UVC lamp can break and cause cut injuries.
• Handle the quartz glass and UVC lamp with care.
N O T E
If the water flow is suddenly interrupted downstream of the outlet (e.g. with a slide valve), this can lead to a
brief increase of pressure of more than 1 bar (water hammer). Possible consequences: The unit may be da-
maged.
• Switching off: First switch off the pump, then close the slide valve. If the unit is operated in a filter system,
first take the filter system out of operation.
• Switching on: First open the slide valve, then switch on the pump. If the unit is operated in a filter system,
start up the filter system last.
• Install the slide valve upstream of the inlet.
Prerequisite: The device head is removed. (→ Removing the unit head)
How to proceed:
 M
Remove the cleaning rotor.
– Clean the cleaning rotor with a brush under running water.
– Wipe the quartz glass with a damp cloth.
– Replace the quartz glass if it is damaged or very scratched. (→ Replacing the UVC lamp)
Clean the inner and outer surfaces of the casing and inspection window.
Check the profile wear at both ends and the inner surfaces of the cleaning rotor.
– If the profile is worn, the cleaning rotor will rotate sluggishly and has to be replaced.
Push the cleaning rotor onto the quartz glass.
– Ensure that it is correctly positioned.
Fit the unit head. (→ Fitting the unit head)
Replacing the UVC lamp
Replace the UVC lamp after max. 8,000 operating hours (this corresponds to approx. one pond season with continu-
ous operation). This ensures optimum filtering performance.
• Ensure that the identification and capacity data of the UVC lamps used correspond to the information on the unit type
plate.

How to proceed:
 N
Remove the cleaning rotor.
Unscrew the clamping screw counterclockwise.
Remove the quartz glass including the O ring towards the front with a slight turning movement.
Pull out the UVC lamp and replace.
Carefully push the quartz glass including the O ring into the unit head up to the stop, fit the clamping screw and tighten
up to the stop by turning clockwise.
– Clean the O ring, replace if damaged.
– Ensure that the O ring is located in the gap between the unit head and the quartz glass.
