Function description
The filter pump pushes the water into the pressure-tight container where it passes through sev-
eral cleaning stages before returning into the pond.
Cleaning stage “Filtration”
The water flows through the foam filters. Mechanical soiling is retained by the foam filters. Sus-
pended matter and bio sludge settle on the container bottom. Useful bacteria settle on the foam
filters, cleaning the water biologically. Their effect starts at a water temperature of +10 °C.
Foam filter Properties
Blue (10 ppi) High flow rate
Colonisation of bacteria for nitrification, which turns ammonia first into ni-
trite, then into nitrate
Purple (20 ppi)
Red (30 ppi) Lower flow rate
Colonisation of bacteria for nitrification and denitrification, which turns ni-
trate into nitrogen
Cleaning stage “UVC radiation”
Water is subjected to UV-C light from the UVC clarifier. Green algae die, pathogenic agents are
killed.
Bypass
The bypass ensures that only approx. 70 % of the water is subjected to UV-C light. This guaran-
tees sufficient radiation even at high flow rates.
Biological cleaning effect
The maximum biological cleaning effect is achieved when the foam filters are fully colonised by
filter bacteria. On new foam filters, colonisation may take several weeks. Adding starter bacteria
can significantly speed up colonisation.
Cleaning the foam filters
You can use the soiled water from cleaning the foam filters to fertilise your garden.

Installation and connection
Installing the unit
To be taken into consideration for planning:
For operation at a swimming pond: Install the unit at a distance of at least 2 m from the water.
For operation at a pond: You can set up the unit directly at the edge of the pond.
Protect the pressure filter from direct sunlight.
Route the return hose into the pond so that the water returns to the pond e.g. through a wa-
ter course. This enriches the water with additional oxygen.
Ensure that the inlet into the pond is max. 2 m above the filter cover.
Burying the pressure filter
A buried container is barely visible. The stone grey FiltoCap (Art. No. 77831) cover available as an
accessory for the filter cover fits seamlessly into the pond scape.
Dig a hole close to the pond and place the container in the hole down to the maximum burying
depth.
The ground must be firm and horizontal.

36
Installing the pressure filter on level ground
If you choose not to bury the pressure filter, position it so that it is hidden from sight e.g. cov-
ered by bushes.
Install the unit near the pond.
The ground must be firm and horizontal.

Establishing the connections
Hoses with a diameter of 38 mm or 50 mm can be connected to the pressure filter. The respec-
tive hose connectors are part of our scope of delivery.
Use hoses with a diameter of 50 mm to keep the pressure losses in the hoses as low as pos-
sible.
If you use a filter starter for start-up, fill the product into the container prior to carrying out
the following installation steps.
It is easier to remove the filter cover if you first remove all hoses from the filter cover.
Connecting the inlet
Only use pressure hoses approved for at least the maximum pump pressure to connect the out-
let of the filter pump and the inlet of the pressure filter.
Always use a hose clip to fasten the hose on a hose connector.
Connecting the outlet
Use a transparent hose connector with a flow lug. The transparent hose connector will allow you
to assess the water quality after filtration. The flow lug will show you the water flow.
Push the hose onto the hose connector until only two segments on the hose connector re-
main uncovered.
– This will give you a sufficiently large view into the hose connector.
Always use a hose clip to fasten the hose on a hose connector.
FCL0014

38
Connecting the dirt outlet
The soiled water resulting from cleaning can be used for fertilisation. Connect a hose and route it
up to a suitable location (e.g. flower bed).
Use a transparent hose connector with a flow lug. The transparent hose connector will allow you
to assess the degree of soiling of the water when cleaning the foam filters. The flow lug will show
you the water flow.
Push the hose onto the hose connector until only two segments on the hose connector re-
main uncovered.
– This will give you a sufficiently large view into the hose connector.
Always use a hose clip to fasten the hose on a hose connector.
Install the black hose connector with the G2 outer thread on the outlet of the hose. Close the
hose connector with the cover cap and the flat seal.
NOTE
Close the dirt outlet or the outlet of the connected hose with the cover cap and the flat seal.
This prevents unintended emptying of the pond. Only remove the cover cap to drain dirty water.

Commissioning/start-up
NOTE
The unit will be destroyed if it is operated with a dimmer. It contains sensitive electrical compo-
nents.
Do not connect the unit to a dimmable power supply.
The purely biological starter bacteria Oase AquaActiv BioKick activate the filter biology and
ensure maximum performance of your pond filter within only a few weeks. They immedi-
ately start removing nitrite, ammonium and ammonia from the water. We recommend fill-
ing the container with Oase AquaActiv BioKick
during initial start-up,
after manual cleaning or replacing the foam filters,
after long shut-down periods or during start-up after a long winter break.
Start-up sequence:
1. If required, fill the container with Oase AquaActiv BioKick. (→ Removing/positioning the filter
cover)
2. Ensure that the hoses, cover cap for the dirt water outlet and the clamping ring with the
safety latch are firmly connected.
3. Turn the turning valve to “Filter water”.
4. Switch on the pond pump.
5. Only switch on the UVC clarifier when water emerges from the water outlet. (→ Switching the
UVC clarifier on/off)
– Never run the UVC clarifier without water flowing through.
– If you are using Oase AquaActiv BioKick, leave the UVC clarifier turned off for 24 hours. This
allows the starter bacteria to achieve optimum effectiveness.

40
Switching the UVC clarifier on/off
Switching on: Plug the power plug into the outlet.
– The unit switches on immediately.
– The indicator lamp lights up.
– The flow lug on the outlet will show you that water is flowing.
Switching off: Pull the power plug from the outlet.
FCL0015
Operation
The pressure filter can remain in operation for the full pond season (the filter pump and the UVC
clarifier are switched on).
The biological filter elements are no longer active at water temperature of less than 10 °C.
Shut down the unit at water temperatures below 8 °C or at the latest when freezing tempera-
ture are to be expected. (→ Decommissioning/winter storage)
The UVC lamp is a wear part. Replace the UVC lamp after a specific operating duration to en-
sure optimum filter performance. (→ Replacing the UVC lamp)
Maintenance and cleaning
NOTE
Do not use aggressive cleaning agents or chemical solutions. These agents can damage the
housing, impair the function of the device and harm animals, plants and the environment.
Only clean the unit from the outside with clear water and a soft brush.

EN
41
Cleaning the foam filters
The Easy Clean function is used to clean the foam filters. During cleaning, the filter pump is
switched on so that the dirt water is transported out of the pressure filter.
Turn the turning valve to guide the water in the container to the dirt water outlet. This pre-
vents the dirt water from flowing back into the pond.
– Beforehand, remove the cover cap from the outlet hose for the dirt water.
Pull the cleaning handle to compress the foam filters. The dirt particles are removed and flow
with the water via the dirt water outlet, for instance to a flower bed.
The transparent hose connectors allow you to check the water flow and assess the degree of
soiling in the water during cleaning on the dirt water outlet. As soon as the water runs clear,
turn the turning valve back to “Filtering”.
After cleaning, close the dirt water hose or the dirt water outlet with the cover cap and the
flat seal.

FCL0018

EN
43
Positioning the filter cover
Ensure that the O-ring on the container is positioned correctly on the container rim.
– Moisten the seal with water or grease the seal, if necessary, so that the filter head is easier
to push onto the container.
Evenly and forcefully push the filter cover as far as possible onto the container.
– The filter ring must make full contact with the container, otherwise the clamping ring will
not close.
Fasten the filter cover with the clamping ring and close the locking latch.
– The locking latch prevents the clamping ring from coming loose accidentally, which would
cause pond water to leak in an uncontrolled manner.
– Use flat nose pliers if the locking latch is hard to move.
Attach all hoses (screw hose connectors in place).

Removing/installing the UVC unit head
CAUTION
The ultra-violet radiation of the UVC lamp can damage your eyes and skin.
Never operate the UVC lamp outside out the casing or in a damaged casing.
Disconnect the unit from the power grid before starting any maintenance work or before re-
placing the UVC lamp.
CAUTION
The quartz glass and UVC lamp could break and cause cuts.
Act with caution when performing work on the UVC clarifier in order to avoid cuts.
Avoid shocks, impacts and abrupt movements to prevent the glass from breaking.
For safety reasons, the UVC lamp can only be turned on when the UVC clarifier is properly
installed in the unit.
Removing the UVC unit head
How to proceed:
First pull the power plug of the UVC clarifier before removing the UVC unit head.
Remove the locking screw, undo the opening ring and remove the UVC unit head.
If it is not possible to remove the UVC unit head, a vacuum has built up in the quartz glass as a
result of the UVC lamp cooling down.
– Remedy: Switch on the UVC clarifier. The heat of the UVC lamp reduces the vacuum and the
UVC unit head is pushed up with a plopping sound. Pull the plug of the UVC clarifier and re-
move the UVC unit head.
