•Although ultraviolet radiation is the lowest in energy of all types of ionising radiation, it can be
harmful to human beings and other organisms. Even UV radiation with a bigger wavelength is
already able to destroy chemical bonds of organic molecules. It is therefore advisable to use
technical UV sources responsibly.
•Only operate the tube inside a closed and intact housing.
Warning!
Read all safety precautions and instructions. Failure to obey the safety precautions and instructions
might cause an electric shock, a fire, and/or severe injuries.
Keep all safety precautions and instructions for future use.
Resistance
•The maximum temperature of the pumped liquid should not exceed +35 ℃ in continuous oper-
ation.
•The pump must not be used to pump flammable, gassing, or explosive liquids. The pump must
not be used to pump other liquids, especially motor fuels, cleaning agent, or other chemical
products.
Electrical connection
The electrical connection is made to an earthed socket 230 V ~ 50 Hz. Fuse protection at least 6 A.
Caution!
•The UVC filter should be placed in such a way that no water may reach it. The minimum distance
between the device and the pond is 2 m. The lamp is not suitable of underwater operation.
•The power supply of the UVC filter must not be switched on before water circulates inside the
device.
•Place the UVC filter in a safe and stable place, as the sleeve of the filter is made of very fragile
quartz glass.
•Do not switch on the power before all parts of the device are completely assembled.
•In case the quartz glass sleeve and the upper part of the UVC filter are damaged, the device
cannot be put into operation.
•The UVC filter must not be used if people are in the water.
•Make sure that the existing mains voltage and frequency match the specifications on the filter.
•While installing the device, local and national installation prescriptions must be obeyed.
•Do not pull on the power cord. Keep the cable away from heat, oil, or sharp edges.
•Make sure that the upper part is only exposed to a pressure below 0.3 bar.
•Remove the filter with frost announced.
•When installing the UV filter, do not expose it to direct sunlight.
•A dirty quartz crystal glass tube affects the efficiency of the device; thus, regularly clean it.
•For the device to keep its efficiency, the UV glass sleeve should be replaced after 8,000 hours
of operation.
•UV radiation is harmful to eyes and skin. Do not directly look into the UV light and do not expose
your skin to UV light.
•When installing or maintaining the device, switch off the power supply of the lamp and pump.
•The product must be mounted horizontally, the feet pointing downwards. For safety reasons, it
is not allowed to install the device in another way.

Use
•The pressure pond filter with integrated UV clarifier is a pressure filter system for biologically
and mechanically filtering normal pond water with a temperature between +4 ℃ and 35 ℃. This
pressure pond filter is only intended for private use for cleaning garden ponds with or without
fish.
•Only water may be filtered!
Working principle
A
Inlet
The pump is connected to the inlet via a pressure hose.
B
Vortex system
Gravity is used to separate suspended and muddy particles.
C
Mechanical filtering
Dirt particles are absorbed at the surface of the filter sponges before the water reaches the
inner part of the filter.
D
Biological cleaning
Microorganisms settle on the pores of the filter sponges. The blue and yellow filter sponges
are different in size and density. This is why zones form where the rapidity of the water flow
is different. In high-speed zones (blue filters), microorganisms settle that convert ammo-
nium into nitrate. In zones where the water flow rate is slower (yellow filters), mainly anaer-
obic microorganisms gather that convert nitrate into nitrogen.

E
Cleaning the pond water
When outflowing, the water is shortly exposed to ultraviolets rays emitted by the UV lamp.
Thus, germs, bacteria, and algae are eliminated. The water circulation in the filter is from
outward inwards.
F
Water backflow
The cleaned water flows back into the pond through a pressure hose.
G
Cleaning outlet
For the filter to be cleaned, a drain hose can be connected that directs the dirty water to
the sewers or a flowerbed.
H
Functional switch
With the help of the functional switch, you can switch from “filter” to “clean” mode.
I
Motor
The motor drives the automatic cleaning mode.
Definition: Clear water
We speak of clear water when you see the fish and pond bottom at a depth of 1 m.
Installing the filter
1. Install the filter so that it is protected against flooding and cannot fall into the pond. It should
therefore be placed at a minimum distance of 2 m from the pond.
2. Dig a hole near the pond and appropriately fix the filter.
3. Make sure that the cover of the filter can be opened.
4. With a lifting height of more than 1 m being required, you should perhaps use a more powerful
pump.
Hose connection
We recommend that you heat up the hose with warm water before attaching it to the stepped hose tail
and fixing it with a hose clamp; thus, it cannot come off.
•Use a hose with the largest possible diameter.
•With hoses longer than 4 m, it is advisable to use a hose tail with the largest possible diameter.
•To minimise pressure losses, cut off the parts of the stepped hose tail that you do not need.
Cleaning outlet
You can direct the dirty water directly to the sewers or a flowerbed.

Operating the pressure filter
Before operating the pressure filter, always check gaskets, connections, and clamps for correct assem-
bly. Adjust the switch to the “filter” position. Do not fail to familiarise yourself with the safety regulations
before commissioning.
•Switch on the pump.
Attention! Never operate the UV lamp without water flowing past it.
•Check the connections for possible leaks.
•Connect the device to the power supply.
•The filter system with integrated UV lamp must operate 24/7.
•Replace the UV lamp after 8,000 hours of operation in order that the device keeps its highest
efficiency.
•The filter sponge must regularly be cleaned.
Attention! After reinstallation, the pressure filter will reach its full biological cleaning efficiency
after a few weeks. The bacteria can only work at best at a temperature of +10 ℃.
Cleaning the filter sponges
Suspended and dirt particles collect in the filter sponges. These accumulations reduce the efficiency of
the filter; thus, the filter sponges need to be cleaned regularly, e.g., every week.
Furthermore, the filter sponges should be cleaned whenever the water is muddy or dirty (whenever the
red control lamp blinks).
1Clockwise adjust the switch to the “clean” position.
2The filter will automatically switch to cleaning mode.
3The filter is rinsed. As soon as clear water flows through the transparent stepped hose tail,
counter-clockwise turn the switch to the “filter” position.
4The filter is now operational again. Check the water flow towards the pond.
Replacing the filter sponges
If the water flow is too low due to dirty filter sponges and cannot be improved by automatic cleaning, the
filter sponges must be cleaned or replaced.
Do not use any chemical cleaning agents for not to destroy the microorganisms settled in the filter
sponges.
1. Pull out the plug of the filter.
2. Switch off the pump, making sure that it cannot unintentionally be switched on
again. Remove all hoses by unscrewing and removing the connecting nuts.
3. Remove the protective cover and open the clamp.
4. Remove the lid and place it upside down on a clean surface.
5. Turn the inlet connection counter-clockwise and unscrew the screws.
6. Replace the filter sponges.
7. Remove the filter sponges, clean them under running water. Wring them out well!
8. Clean the container, filter sponges, O-ring 3, and container edge with the help of a hosepipe.
9. Place the sponge on a separate surface and fix the tube inlet.
10. Replace O-ring 3 on the upper container edge (wetting it beforehand). Press the lid down.
11. Fix the clamp to the correct spot, push the safety latch forward.
12. Attach all hoses with gaskets to the appropriate connections points and tighten the connecting
nuts.
13. Switch on the pressure filter.
