Maintenance and cleaning
Cleaning the quartz glass
Attention! Breakable glass.
!
Possible consequences: Injury to your hands caused by cuts.
Protective measures: Handle the quartz glass and UVC lamp with care.
Note! 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 14.5 psi (1 bar) (water hammer).
Possible consequences: The unit may be damaged.
Protective measures:
• 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. (See Removing the unit head)
1. 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. (See Replacing the UVC lamp)
2. Clean the inner and outer surfaces of the casing and
inspection window.
3. 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.
4. Push the cleaning rotor onto the quartz glass.
○ Ensure that it is correctly positioned.
5. Fit the unit head. (See Fitting the unit head)
