Maintenance and cleaning

Attention! Dangerous electrical voltage.
Possible consequences: Death or severe injury.
Protective measures:
− Prior to reaching into the water, switch off the mains voltage to all units used in the water.
− Switch off the mains voltage prior to carrying out work on the unit.
Attention! Breakable glass.
Possible consequences: Injury of your hands caused by cuts.
Protective measures: Handle both quartz glass and UVC lamp with care.
Attention! Water hammer. If the water flow is shut off suddenly, a pressure increase of over 1 bar can cause
water hammer.
Possible consequence: The UVC unit will be destroyed.
Protective measure:
− First switch off the pump and then shut off the water flow through the unit with the slide valves.
− If the unit is operated in a filter system, first shut down the filter system.
− To start up again, first open the slide valves, then switch on the pump and/or start up the filter system.
Note!
A safety switch prevents switching on the UVC lamp as long as the UVC water housing is removed.
Cleaning the UVC quartz glass tube
How to proceed:
J
− Switch off the unit and take all measures to avoid water hammer.
− Open the unit: First press the engagement hook, then turn the unit head (11) counter-clockwise through approx. 30
degrees.
− Slightly tilt the unit head with the UVC lamp and carefully remove. Ensure that the transport protection (14) on the
quartz glass tube is retained.
K
− Check the O ring (13) on the unit head for damage and replace if necessary.
− Wipe the quartz glass tube with a damp cloth
− Reassemble the unit in the reverse order.
Replacing the UVC lamp
Note!
− Condensate forms in the quartz glass tube. This condensate cannot be avoided, however, it does not impair
function and safety.
− The quartz glass tube can become scratched or blind over time. In this case, sufficient cleaning perform-
ance of the UVC lamp is no longer guaranteed. The quartz glass tube must be replaced.
− The UVC lamp must be replaced after approx. 8000 operating hours. Only use UVC lamps the designation
and rating of which match the information on the type plate.
