Installation
Installation of the UVC clarifying unit (A1-A3)
Lift the filter cover by pulling off the two cover lugs. Turn the unit head counter-clockwise against the stop, then care-
fully pull off. Push the two screws into the guides of the UVC housing and fit the filter lid. Turn one washer and one nut
each against the screws from below. Screw the stepped hose adapter including sealing ring onto the UVC inlet. Screw
the inlet bracket including sealing ring onto the UVC outlet.
Fit a UVC lamp (E2-E6)
Unscrew the clamping screw from the UVC clarifying unit counter-clockwise, pull off the quartz glass including the O
ring forward by slightly turning, insert UVC lamp, refit the O ring on the quartz glass and push the glass into the unit
head through to the stop. Press the O ring into the gap between unit head and quartz glass. Screw in the clamping
screw clockwise and manually tighten. Position the large O ring in front of the recess at the unit head. Carefully push
the unit head into the housing while applying slight pressure. Ensure that the tenons at the housing engage in the
grooves of the bayonet closure. Turn the unit head clockwise against the stop while applying slight pressure (the two
arrows on the housing and the unit head meet). Note: If the unit head cannot be completely pushed on, check that the
clamping screw is fully screwed in against the stop. Press the filter lid including the UVC clarifying unit onto the filter
housing.
Note: Because of a built in safety switch, the lamp will only light up when the installation of the UVC clarifying
unit is completed.

Installation
Install Filter (B1)
Position theflow-through filter at a place which cannot be flooded and as horizontal as possible at least 2 m from the
pond edge on a firm and level ground above the pond water level. The outlet position must be a maximum of 1 m
above the pond surface. Do not expose the unit to direct sunlight. Ensure unrestricted access to the cover to enable
working on the unit. Place the unit in the pond horizontally on firm, sludge-free ground and ensure that it is completely
covered with water at a maximum of 2 m below the surface of the water.
Connect Inlet and Outlet (B2)
Connect the UVC inlet to the filter pump outlet using the enclosed hose. You may connect e.g. an HT tube (DN 50) or a
2" hose with a hose clip at the filter outlet.

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).
