Attention! Never operate the unit without water flowing through!
Start-up (C)
Adhere to the safety information given above! Connect the filter pump power plug (C1) and wait until the flow-through
filter is filled with water. Connect the power plug of the UVC lamp (C2), the blue control lamp is lit. 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 an operating temperature of + 10°C. Note: In the event of overheating, the installed temperature
monitor switches the UVC lamp off automatically, the lamp automatically switches on again once cooled down. Dis-
connect the power plug to switch the units off (C3, C4).

Maintenance and cleaning

Attention! Prior to starting cleaning and maintenance work, always disconnect the power plugs of the UVC
pre-clarifying unit and of the filter pump (C3, C4)!
Adhere to the safety information given above! Check and clean the water outlet into the pond at regular intervals. We
recommend to clean the filters at regular intervals (e.g. every four weeks), however, at the lastest when cloudy or dirty
water from the water outlet returns to the garden pond. Never use chemical cleaning agents.
Cleaning the filters (D)
Remove the filter lid including the UVC clarifying unit from the filter housing, remove the foam filters and clean them
under running water by compressing them vigorously. Gently rinse the Matala mat and the bio surface elements with
clean water (not under running water), lightly shake out. Completely empty the filter housing and clean under running
water. Reassembly the filters in the reverse order, start the filter pump first (C1), then connect the power plug of the
UVC pre-clarifying unit (C2).
Clean the quartz tube of the UVC pre-clarifying unit (E)
Disconnect the power plug of the UVC pre-clarifying unit and of the filter pump (C3, C4) and protect from unintentional
switching on again. Turn head of the UVC clarifying unit counter-clockwise against the stop and gently pull off, turn off
the clamping screw of the UVC clarifying unit counter-clockwise, then pull the quartz glass including the O ring to the
front with a slight turning motion, remove the O ring from the quartz glass, clean and check the O ring for damage.
Clean the quartz glass outer face with a moist cloth and check for damage.
Replacing the UVC lamp (E3)
Change the UVC lamp after approx. 8,000 operating hours. Pull out and replace the UVC lamp.
Important! Only use lamps the designation and rating of which match the information on the type plate.
Check components for damage and replace, if necessary. Check the O ring at the unit head for damage, then reas-
sembly the UVC clarifying unit in the reverse order. Restart the filter pump first (C1), then connect the power plug of the UVC
pre-clarifying unit (C2).
Cleaning the filter pump (F)
Take pump out of the water, unscrew the stepped hose connection including the O ring from the connection thread,
actuate the engagement hook of the filter housing, open the filter housing and remove the pump. Turn off the pump
housing, remove the impeller. Clean the pump housing, the impeller and the filter housing using clear water and a
brush. After cleaning, fit the unit in the reverse order.
Storage/Over-wintering
Put the unit out of operation at water temperatures below 8 °C or, at the latest, when freezing temperatures are to be
expected. Drain and thoroughly clean the flow-through filter, check for damage. Remove, clean, dry and store all filters
in a frost-free environment. Store the filter pump submerged or filled in a frost-free environment. Do not immerse the
plugs! Ensure that the storage place is inaccessible to children. Cover the filter container such that the ingress of rain
water is excluded. Drain all hoses, pipes and connections as far as possible.
