1
Water return socket, for the return of filtered pond water
2
Water inlet socket, for the inlet of soiled pond water
3
Cleaning handle, the foam filters are compressed by pulling the handle up
4
UVC unit head with temperature monitor, holder and control window for UV-C lamp. The UV-C lamp switches off automatically when
overheated and on again once cooled down.
5
Function switch to reverse the water flow. Turn counter-clockwise. 3 positions are available.
I: Water filtering and radiation
II: Foam cleaning („Easy-Clean Technology“)
III: Flushing the UVC unit and the UVC water housing
6
Bypass, optimises the UVC radiation effect at a high flow rate
7
Soiled water drain socket, to drain the soiled water
8
Filter lid
9
Cover cap, with black flat sealing ring inserted
10
Clamping ring to hold filter lid and container together
11
Step, marking the maximum installation depth
12
Container, pressurised when the unit is in operation (max. 0.2 bar)
13
Fine foam filter for nitrification and denitrification
14
Coarse foam filter for nitrification
15
Fixing disk, holding foam filters on cleaning rods
16
Cleaning rod, connecting cleaning handle and filter disk
17
Meshed tube, maintaining the foam filter spacing to the UVC water housing
18
UVC water housing, conveying water to the UVC unit
19
Quartz glass tube with UV-C lamp
Function description
 A
A filter pump (only contained as a set in the scope of delivery) presses the water into a pressure-tight container, where
it passes several cleaning stages before returned into the pond. The soiled water resulting from cleaning the unit can
be used to fertilise the garden.
 B
Cleaning stage "filtering": The water flows through the foam filters. Mechanical soiling is retained by the foam filters.
Suspended matter and bio sludge settle on the container bottom. Usseful bacteria settle on the foam filters, cleaning
the water biologically. Their effect starts at a water temperature of + 10 °C.

Bacteria for nitrification
Bacteria for nitrification and denitrification
Ammonia -> nitrite -> nitrate reaction
Nitrate -> nitrogen reaction
Cleaning stage "radiation": The water is radiated with the ultra-violet light from a UV-C lamp. Green algae die, patho-
genic agents are killed.
Bypass: A bypass ensures that only part of the returning water (approx. 25 %) is radiated. In this manner a sufficient
radiation duration is obtained even at a high circulation rate.
Filter starter: The unit only reaches its full biological cleaning effect after a few weeks. The formation of a bacterial
community on the foam filters can be notably accelerated by adding filter starter bacteria.
