Function description
The filter pump presses the water into a pressure-tight container, where it passes several clean-
ing stages before returned into the pond.
Cleaning stage "filtering"
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 colonize the foam
filters, cleaning the water biologically. Their effect starts at a water temperature +50 °F ( +10 ) °C.
Foam filter
Properties
Blue (10
ppi)
High flow rate
Bacterial colonization for nitrification so that ammonium is first converted
to nitrite and then to nitrate
Purple (20
ppi)
Red
(30 ppi)
Low flow rate
Bacterial colonization for nitrification and denitrification to convert nitrate
to nitrogen
Cleaning level “UVC radiation”
The UVC clarifier irradiates the water with UV-C light. Green algae die, pathogenic agents are
killed.
Bypass
The bypass ensures that only approx. 70 % of the water is irradiated with UV-C light. This means
a sufficient radiation dosage is achieved even with high flow rates.
Biological cleaning effect
The maximum biological cleaning effect is achieved when the foam filters are fully colonized by
filter bacteria. This may take several weeks for new foam filters. Adding starter bacteria can sig-
nificantly accelerate the colonization process.
Cleaning foam filters
You can use waste water generated by cleaning foam filters to fertilize 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 min. 6.6 ft (2 m)
from the water.
•For operation at a pond: You can install the unit directly at the edge of the pond.
•Protect the pressure filter from direct sunlight.
•Route the return to the pond so that the water is returned to the pond e.g. through a water
course. This enriches the water with additional oxygen.
•Ensure that the inlet into the pond is max. 6.6 ft (2 m) above the filter lid.
Bury the pressure filter
A buried container is barely visible. The FiltoCap stone gray (art. no. 91645) cover for the filter lid,
available as an accessory, blends seamlessly into the pond landscape.
•Dig a hole close to the pond and place the container in the hole down to the maximum em-
bedding depth.
•Ensure that the ground is firm and horizontal.

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 1½ in (38 mm) or 2 in (50 mm) can be connected to the pressure filter.
The corresponding hose connectors are part of our scope of delivery.
Use hoses with a diameter of 2 in (50 mm) to keep the pressure loss in the hoses as low as
possible.
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

EN
13
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.

EN
15
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 entire pond season (the filter pump and the
UVC clarifier are switched on).
•At water temperatures below 50 °F (10 °C), the filter biology is no longer active.
•Take the unit out of operation at water temperatures below 47 °F (8 °C) or, at the latest, when
freezing temperature 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 optimal filtration power. (→ 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.

16
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.

Removing/positioning the filter cover
Removing the filter cover
How to proceed:
•Switch off the filter pump and pull the power plug of the UVC clarifier from the outlet.
•Remove all hoses from the filter cover (unscrew hose connectors).
•Undo the locking latch.
– Use flat nose pliers if the locking latch is hard to move.
•Open the clamping ring and remove the filter cover.
FCL0018

18
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).
