Cleaning the unit and washing or replacing the foam filters
Wear of the foam filters is caused by mechanical stress and normal ageing. OASE recommend: Replace old foam fil-
ters with new ones at the beginning of the new season.

Possible death or severe injury from hazardous electrical voltage!
• Prior to reaching into the water, isolate (switch off and disconnect) all units/devices used in the water.
• Isolate the device (disconnect from the power supply) before carrying out any work on it.
How to proceed:
• Switch off the filter pump.
• Remove all hoses, hose connections (M).
• Remove the UVC unit head (4) (Cleaning and maintenance\Removing/inserting the UVC unit head).
• Open the container (Cleaning and maintenance\Opening the container).
• Remove the lid including the stack of foam filters (N 39) and place on a soft clean surface such that the fixing disk
(15) of the stack of foam filters faces upward.
Disassembling the foam filters
• Check the foam filters, and either wash or replace.
• Remove the filter disk (N 15) after loosening and removing the two screws (43).
• Pull off the foam filters.
Cleaning the parts
Figure B
• Clean the container, clamping ring, lid (remove UVC unit head!) including UVC water housing (18) and the meshed
tube (17) from all anlges with a strong water jet.
• If necessary, wash the foam filters individually by vigurously compressing and releasing the filters under running water.
Assembling the foam filters:
Figure (P, Q)
• Alternately push the blue (14) and then the red (13) foam filter onto the cleaning rods (16), so that the cleaning rods
rest in the two cut-outs.
• Place the fixing disk (15) on the last foam filter such that the end collar (44) points to the foam filters.
• Fasten the fixing disk on the cleaning rods using the two screws (Q 43).
• Reinstate all connections ( Assembly).

Quartz glass and UVC lamp can break and cause cut injuries.
• Handle the quartz glass and UVC lamp with care.
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 per-
formance 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 des-
ignation and rating of which match the information on the type plate.
