An optional adapter set is available for the cleaning outlet (A3). For this purpose, remove the cover cap from the
cleaning outlet. Push the union nut over the hose, slide the stepped hose adapter without thread onto the hose end
and secure with the hose clip. Connect the stepped hose adapter with union nut and flat seal to the cleaning outlet.
Push the stepped hose adapter with thread onto the other hose end, secure with the hose clip and screw on the cover

This is how to connect the power supply:
Switching on: Connect the unit to the mains. The unit switches on as soon as the power connection is established.
Switching off: Disconnect the unit from the mains.
Check the correct seating of hoses and cover cap prior to starting up. Never operate the UVC clarifying unit without
water.
Switch on the pump and wait until the filter housing is filled with water. Check all connections for leaks.
Connect the power plug of the UVC clarifying unit, the blue control lamp is lit (B). In the event of overheating, the
temperature monitor switches the UVC clarifying unit off automatically, the UCF clarifying unit automatically switches
on again once it has cooled down.
Note: After a new installation, the unit only reaches its full biological cleaning effect after a few weeks. The full effect
on bacteria is only reached as from a water temperature of + 10 °C.
Maintenance and cleaning
Attention! Dangerous electrical voltage.
Possible consequences:
Death or severe injury.
Protective measures:
•
Electrical units and installations with a rated voltage of U > 12 V AC or U >30 V DC located in the water:
Isolate the units and installations (switch off and disconnect from the power supply) before reaching into the
water.
•
Isolate the unit before starting any work.
•
Secure the unit to prevent unintentional switching on.
Attention! Ultra-violet radiation.
Possible consequences:
Eye or skin injury from burns.
Protective measures:
•
Never operate the UVC lamp outside its housing.
•
Never operate the UVC lamp in a housing that is defective.
Attention! Breakable glass.
Possible consequences: Injury to your hands caused by cuts.
Protective measures: Handle the quartz glass and UVC lamp with care.
C, D
Adhere to the safety information given above! Check and clean the water outlet into the pond at regular intervals.
Clean the filters at regular intervals (e.g. every four weeks), however, at the latest when cloudy or dirty water from the
water outlet returns to the garden pond. Carry out quick cleaning first. Should this prove insufficient, clean the entire
unit. Never use chemical cleaning agents.
Quick cleaning (C2, C3)
Open and remove the filter lid from the filter housing (C2). Pull the cleaning handles several times (C3). This causes
the foam filters to compress and be mechanically cleaned. Open the cover cap at the cleaning outlet and drain the
soiled water. Screw the cover cap back on again and start the unit up (see Start-up).
