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.
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).
Complete cleaning (C2 – C5)
Open and remove the filter lid from the filter housing (C2). Unlock and remove the inner cover (C4). Press both en-
gagement hooks at each of the foam filter holders sideward, then remove holders including foam filters (C5). Remove
the foam filters from the holders and clean with clear water. Open the cover cap at the cleaning outlet and clean filter
housing, inner lid and cover with water. Reassemble the filter in the reverse order. Arrange the foam filters in water
flow direction: Coarse foam filters (blue) first, then fine foam filters (red). Screw the cover cap back on again and start
the unit up (see Start-up).
Cleaning the UCV clarifying unit (D)
Open and remove the filter lid from the filter housing (C2). Turn the unit head of the UVC clarifying unit counter-clock-
wise against the stop, then carefully pull off (D1). Loosen the self-tapping screw until the the screw tip is sunk in the
housing of the clamping screw (D2). Undo the clamping screw by turning counter-clockwise, and remove the quartz
glass including the O ring forward with a slight turning movement (D2). Remove the O ring from the quartz glass, clean
and check for damage. Clean the quartz glass outer face with a moist cloth and check for damage. Thoroughly clean
the inner and outer surfaces of the housing. If necessary, replace the UVC lamp (D3).
Reassembly: Push the O ring against the collar of the quartz glass, press the quartz glass into the unit head against
the stop, fit the clamping screw and hand-tighten (D4). Tighten the self-tapping screw (D4). Check the O ring at the unit
head for damage, fit the O ring and push the unit head carefully into the housing while exerting light pressure (D5). En-
sure that the tenons at the housing engage in the grooves of the bayonet closure. Turn the unit head clockwise up to
the stop while applying slight pressure, so that the two arrows on the unit head and the housing meet (D6).
Changing the UVC lamp (D3)
For an optimum filter performance, we recommend to replace the UVC lamp after approx. 8000 operating hours.
Important! Only use lamps the designation and rating of which match the information on the type plate.
Pull out and replace the UVC lamp.
