Description
WilTec pressure filters are an ideal and easy filter system for your garden pond. The
filters dispose of various advantages in contrast to commonly used filter systems:
◊large cleaning capacity
◊the combined mechanical and biological filtering (depending on the kind of model
◊effective filter materials
◊integrated UVC unity as well as waste display
◊remains waterproof even at a high pressure
◊water delivery up to 3 m in height (dependent on the capacity of the pump that is
connected)
◊easy installation and maintenance of the filter
Functions of the WilTec pressure filter
The WilTec pressure filter purifies the water in 3 stages:
1. The first stage is mechanical. The visible dirt particles are removed by 3 layers of
filter sponges structured from coarse to fine.
2. The second stage is biological. By means of so-called bio balls (depending on the
model) the accumulation of bio-organisms is stimulated. These microorganisms re-
move organic components from the pond water (depending on the model).
3. The third stage consists of a UVC treatment of the water. The UVC light kills algae
and germs.The result: healthy water.

Installation of the pressure filter
1. Place the pressure filter in a way so that it is not
flooded or falls into the pond; it should be in a
distance of at least 2 m from the edge of the
pond.
2. Make sure that it is placed on a smooth surface.
3. To simplify the handling of the pressure filter,
make sure that you can easily operate the open-
ing.
4. The outlet of the water back to the pond should 2
m at a maximum above the filter lid (0,2 bar of
water pressure)
5. The pump should be turned on first.
Commissioning of the pressure filter
Before commissioning make sure that any and all cable and hose connections are
installed correctly. The switch must be set to “filter function”. Before first operation the
safety instructions have to be read:
1. Switch on the pump. Attention! The UV lamp must not be operated before the
pump delivers water.
2. Check that all connections are resistant to water.
3. Turn on the pressure filter.
4. The filter system with the integrated UV lamp has to be permanently operated 24
hours a day.
5. The UV lamp should be replaced after an operational period of 8000 hours in order
to guarantee an optimal efficiency of the system.
6. The filter system should be cleaned regularly.
Attention: In case of primary / new installation the cleaning capacity will be fully
reached only after a few weeks, after the necessary microorganisms have grown.
This will be especially the case with an ambient temperature above + 10°C.
The UVC lamp must not be operated as long as it is not flooded by water.
Never use the UVC in case there is a damage on the lamp or connection.
Never use the UVC filter in case there are people in the water.
In case of an overheating, the installed temperature sensor inside the UVC filter
switches off automatically the UVC lamp in case of an overheating.
After cooling down, it is automatically switched on again.
The WilTec pressure filters are supplied completely with all necessary filter mats. Be-
fore use rinse them carefully with pond water.
The bio filter balls (depending on the model) are placed on the bottom of the filter, the
grate with the protective tube for the UVC unit is inserted above. Here you place the
filter sponges, ascending from fine to coarse. Set the lid and close the filter by means
of the enclosed clamp. When installed correctly, the filter is waterproof up to a work-
ing pressure of 0.5 bar. The power supply has to be equipped with a FI – fault current
protection switch that must not exceed 30 mA.

cutting orifice
Hose connector / assembling closing cap:
Slide the nut on the black stepped nozzle. Insert the flat gasket into the nut and
screw it on the water inlet stub and the water outlet stub respectively. Screw the clos-
ing caps on the clean stub.
Connecting the water inlet:
The pump is connected to the nozzle showing the direction of arrow to the filter.
Make use of a hose diameter that is equal to that one of the pump outlet. Saw off the
unused diameter of the hose nozzle.
Connecting the water outlet:
The hose nozzle showing direction of arrow from the filter is the outlet towards the
pond. Connect an appropriate hose to the largest diameter of the nozzle and saw off
the remaining diameter. Make use of hose clamps to prevent loosening of the tubes.
We recommend the heat the hoses with warm water to facilitate the attachment to the
connection.
Connecting the cleaning connection:
In order to mount a drain hose permanently on a cleaning connection (Clean), screw
off the closing cap from the cleaning connection (Clean), mount the third hose nozzle
along with an appropriate hose. When filter-operated, the cleaning connection or the
assembled drain hose have to be closed at any time by means of the closing cap or
an inserted flat gasket. This is meant to be a security in case the switch is set to
“Clean” inadvertently.
Attention! Never operate the device without water flow or without pump filter!
Operating mode of the pressure filter
The pressure filter with its integrated UVC is a sealed filter system for the biological
and mechanical cleaning of pond water.

A: Water inlet
The pump is connected by means of a pressure hose to the water inlet.
B: Swirl-System
By means of gravity floating particles and contaminants settle down.
C: Biological cleaning
Microorganisms accumulate on the filter sponges´ pores. The blue and yellow
filter sponges differ in size and density. With different speeds, the water flows
through the different zones. As for the zones with a high flowing speed (blue fil-
ter), there settle mainly microorganisms that convert ammonia into nitrate. As for
the zones with a lower flowing speed, the growth of anaerobic microorganisms is
particularly supported which in turn oxidize nitrate to nitrogen.
D: Mechanical filter
Dirt particles are retained on the surface of the filter sponges before the water
flows towards the filter inside.
E: Cleaning of the pond water
When flowing out, the water is exposed to the ultraviolet radiation of the UVC
lamp thus killing germs, bacteria and algae. When flowing through the filter, the
water circulates from the outside to the inside.
F: Water outlet with flow indicator
On the outlet the cleaned water is led back into the pond.
G: Cleaning connection
Here, a hose can be connected in order to clean the filter. This is to remove the
accumulated dirt.
The waste water can be directly disposed of or used to water the flower bed.
H: Function switch
For selectively switch between „filtering“ and „clean filter“
I: Cleaning handle
The filter sponges can be cleaned manually by turning the cleaning handle.

Connecting the pump:
Make sure that the drain in the pond is placed in a clean place.
In case the drain is blocked, there can be a higher pressure. This in turn can lead to a
leak inside the filter, thus effecting a complete drainage of the pond. When the filter is
used in “filter mode” it has to be ensured that all gaskets are mounted correctly in
order to prevent the complete drainage. The sealing cap also serves as a security
means in “clean mode”. Make sure that the filter always operates in “filter mode” as
long as the pump is operating. The filter should be only set to “clean” when the filter
sponges are cleaned. Before switching off the filter, please check whether all hoses
and gaskets are correctly placed. Never filter any other liquids than water. In freezing
conditions, the filter must be removed. Never put the filter in direct sunlight.
After the filter has been installed in the right place and the pump is connected, the
UVC unit can be switched on.
UVC unit:
The WilTec pressure filters are completely supplied including UVC unit. The UVC-PL
laps have approx. 8000 of active burning hours. This corresponds to a seasonal use
from March to November. The UVC lamp can be easily replaced by loosening the
screws inside the spherical part of the lid.
It is recommended to replace the UVC lamp at the beginning of a season.
The UVC turns green water clear and fights germs. The WilTec pressure filter dis-
pose of a separate space by the means of which the UVC radiation does not get in
touch with the filter media. By this means, the microorganisms inside the filter materi-
al are not damaged.

Maintenance & Cleaning
Waste Outlet
The waste outlet allows the drainage of polluted water – after cleaning the filter
sponges- into drains or a flower bed.
Cleaning the filter sponges
Over the time, caontaminants accumulate in the filter sponges and their cleaning ef-
fectiveness will be reduced. Therefore they should be cleaned when tarnished or
even dirty water flows out the filter and back in the pond. (The indicator lamp on the
cleaning handle turns red)
1. Turn the function switch – until you hear a „click“ – clockwise to the „Clean-
ing“ function.
2. Rotate the cleaning handle several times. Thus, the filter sponges are
pressed and cleaned mechanically. Rotate clockwise and counter-clockwise
rotation to achieve a better result.
3. When the filter is cleaned, you will see if re-flowing clean water through the
transparent hose of the cleaning port. Now the function switch position again
in the "filtration".
4. The filter is now ready for use; Check the water inlet to the pond.

Replacement of the filter sponges
If the flow is too low and it can’t be improved through cleaning funtion, the sponges
has to be washed or replaced.
Please do not use chemical cleaning agents, so as not to kill the microorganisms of
the filter sponges!
1. Unplug the power
2. Turn off the pump and make sure that it can not be reconnected unintentionally.
Remove all nuts and hoses.
3. Remove the safety lock than open the filter.
4. Lift the filter head with the filter sponges assembly. Place it upside down on a
clean surface. The filter sponges are on top.
