Application area/functioning
This UVC device ensures clear water for healthy fish. The water is pumped by a pump through the UVC
device. There it flows past the UV lamp and is exposed to UVC radiation. Thus, the bacteria, germs and
floating algae in the water are destroyed, and the water is clarified.
To achieve an optimal result the device should be operated 24 hours in the frost-free seasons.
Commissioning
Switch on the pump and wait until the device is filled with water. Check if all connections are well sealed.
By plugging in the power cable, the device is put into operation.

WilTec pond filter functions
The WilTec pond filter clarifies the water in 3 phases:
1. The first stage is mechanic. The visible particles of dirt are removed by means of a 3-layer filter
foam, arranged from coarse to fine.
2. The second stage is biologic. With the help of the so-called bio-balls (depending on model) the
settling of bio-organisms is stimulated. These bio-organisms remove the organic components
from the pond water (depending on model).
3. The third stage comprises a UVC water treatment. The UV light destroys swimming algae and
germs. The result is healthy water.
Commissioning
•The pressure filter should be placed at least at a 2-meter distance from the pond edge. The
water outlet back to pond should be placed max. 2 m over the filter cover (0,2 bar water pres-
sure!).
•The pump must be started first. The UVC lamp must not be operated as long as no water flows
through it. Do not use the UVC lamp if the lamp or the connections show damage signs. Do not
use the UVC-filter if there are people inside the water.
•The built-in UV filter temperature sensor stops the UVC lamp. After cooling down, it is automat-
ically re-started.
•The WilTec filter is delivered with all the necessary filter mats. Carefully wash the filter mats with
pond water before using. The bio-balls (depending on model) are placed at the bottom of the
filter, above put the grating with the protective tube for the UVC unit. Then put the filter foam
layers on it, arranged from fine to coarse. Put the cover lid on the housing and close the filter
with the supplied cramping bracket.
•If properly installed, the filter is waterproof up to a 0,5 bar working pressure. The power supply
has to be equipped with an earth leakage circuit breaker that does not exceed 30 mA.

Installing stepped hose tails
Place the coupling rings around the black hose tails, insert the flat gaskets in the coupling ring and screw
it on the water inlet and outflow connection. Screw the hose tails with the flat gaskets on the device.
Connecting to the water inlet
The pump is connected to the hose tail whose arrow is directed towards the filter. Use a hose diameter
which is exactly the same as the diameter of the pump outlet. Saw off the hose steps that you do not
need.
Connecting to the water outlet
The hose tail with the arrow showing away from filter is the outflow towards the pond. Connect a suitable
hose to the large diameter step of the hose tail and saw off the other hose steps. Use hose clamps to
prevent the loosening of the hoses.
Connecting to the cleaning outlet
To install a permanent drain hose to the cleaning connection (Clean), you have to unscrew/remove the
stepped tail to the cleaning connection (Clean), install the third stepped hose tail and connect a suitable
hose. In the filter operation, the cleaning connection or a connected drain hose must be always closed
and sealed with a hose tail (closure cap) and gasket seal, for safety means, in case the function switch
is accidentally set on “Clean.”
Attention! Do not operate the device

Part
Name
Explanation
A
Water inlet
The pump is connected to the water inlet via a pressure hose.
B
Whirl system
The water permeates through the bio-filter materials due to the centrif-
ugal and gravitational forces.
C
Mechanical filter
Dirt particles are retained on the surface of the sponge filter before the
water flows towards the inner of the filter.
D
Biological cleaning
Microorganisms settle on the filter sponge pores. The blue and the
yellow filter sponge differ in size and density. This generates zones/ar-
eas through which the water flows at different speeds. In the zones/ar-
eas with a high flow speed (blue filter), mainly microorganisms settle
that convert ammonium to nitrate. In the areas in which the water flows
faster (yellow filter), mainly anaerobic microorganisms accumulate
that reduce the nitrate to nitrogen.
E
Pre-cleaning of the pond
water
When the water flows out, it is shortly exposed to the UV radiation
emitted by the UV lamp. As a result, germs, bacteria, and algae are
destroyed. The water circulates when flowing through the filter from
inside outwards.
F
Water discharge with
flow display
The cleaned water flows back into the pond.

Cleaning the filter sponge with crank (CPF-2500-5000-10000-15000-20000-30000)
•The filter sponge can be cleaned by turning around the cleaning handle. Installation guidelines
with regard to the clear water guarantee, the following installation guidelines must be observed.
•Please read the following notes in order to ensure that the water always is cleaned sufficiently:
◦The filter system has to remain switched on for 24 hours a day.
◦The UV lamp should be changed after 8000 operating hours so that the device can work
effectively and efficiently. The filter system must be cleaned regularly.
Connecting the pump
•On the filter cover/lid, there are three connections equipped with hose tails:
◦The pump is connected to the first hose tail. Use a hose diameter that is the same with the
diameter of the pump outlet. Saw off the diameter-hose steps that you do not need.
◦The hose tail in the middle of the filter cover/lid is the outflow to the pump. Connect to the
large diameter of the tail a suitable hose and cut away the rest of the tail diameter. To avoid
the loosening of the hoses please use hose clamps.
•Never use the filter with a built-in UVC unit with a water pressure higher than 0,2 bar! The height
difference between the filter lid and the pressure-free outflow point of the supply line can amount
to max. 2 m. The pressure of the water pumped to the filter cannot exceed 0,5 bar. Use the filter
only with hoses that can withstand at least a pressure of 0,2 bar, the max. pressure of the pump.
•Make sure that outflow /discharge in the pond is positioned on a clean place. If the outflow is
blocked a higher pressure may result. Higher pressure can lead to leaking spots in the filter and
therefore to a complete emptying of the pump.
•When the filter is used in “filter-modes,” the user should be careful and make sure that all seals
are properly installed in order to avoid the emptying of the pond. The sealing cap functions
simultaneously as safety measure in “Clean” mode. Make sure that filter always operates in the
“Filter” mode as long as the pump is running. The filter should be set on “Clean,” if the filter
sponges are cleaned. Before you start the filter, check and make sure that all hoses and seals
are correctly fastened. Filter only water and no other fluids. By frost the filter has to be removed.
Do not expose the filter to the direct sun light.
•After the filter has been placed on the right place and the pump has been connected the inte-
grated UV-unit can be switched on.
UV unit
•The WilTec filter is delivered with all the equipment you need, and an integrated UV unit. The
UV lamps have approx. 8000 working hours that correspond to a season period of use from
March till November. The UV lamps can be replaced by loosening the screws from the spherical
upper part of the cover lid.
•It is recommended to change the UV lamp with a new one at the beginning of the season.
•The UV lamp clears as the green water and destroys germs. The WilTec filters have a separate
chamber, through which UVC rays are not exposed to contact with the filter media. Because of
this the micro-organisms in the filter material are not damaged.

Filter operation: Bring the rotating switch Einto position B1.With the help of a pump, the water is led
to the filter through the connection A, where it is cleaned and discharged back into the pond via con-
nection B.
Cleaning operation: Bring the switch Einto position D. This setting enables the cleaning mechanism
by pressing down the setting switch E. By means of this pressure, the sponges inside the filter are
squeezed. By using this switch setting the dirty water is not led back into the pump but it is discharged
via connection Cand it can be used for garden watering.
The pond filter of the series CPF-2500-5000-10000-15000-20000-30000 have a fast-cleaning function
that can be activated with the aid of the crank. Instead of the setting switch (press button) described
above, turn the crank handle (like the one of a salad spinner) until the filter sponges have lost enough
dirt.
The filter materials as well as the lamp should be replaced 1× year
to ensure a problem-free operation of the filter.
When the filter is used for normal operation, “the watering connection” (C) with the screwed ring plus
sealing and the viewing glass (included in the delivery) should be closed to avoid leaking. The pressure
filter model of the series CPF-2500-5000-10000-15000-20000-30000 have a stepped hose tail with in-
tegrated ball valve to close the connection.

Other notes and remarks:
•Before every commissioning of the filter the user should check if sealings and connections are
fitted correctly.
•Pressure pond filters are exclusively designed for filtering pond water with typical impurities.
•Do not expose the filter to the direct sun light over a longer period.
•By frost the filter has to be completely emptied, if necessary, dug out and stored in a dry, frost-
free place.
•After work that requires the removal of the lid, please make sure when attaching the cover lid
that the sealing rings are fitted correctly! Fit the clamp ring around the lid, press on the cover lid
and close the sealing clam.

Changing the light tube
If the algae proliferate, it is necessary to check the correct the functioning of the UV-C lamp. You rec-
ognise on the UV-indicator if the lamp lights at all. Change it every season.
CPF-180/CPF-250
CPF-2500-5000-10000-15000-20000-30000
•Before changing the UV lamp disconnect the pump.
•Release the 8 screws of the UV unit from the filter lid.
•Carefully remove the UV lamp.
•After the UV unit has cooled down and dried up, grab the base of the light tube (not the glass!)
with a soft cloth and pull it cautiously out of its socket.
•Now the quartz glass inside which the light bulb is placed must be cleaned. For this purpose,
the lime has to be dissolved under heating with appropriate agents (coffee machine or kettle
descaler like citric acid). After this rinse the quartz glass from residues remaining from the clean-
ing agents.
•After rinsing all parts are reassembled in reverse order. The pump and the device are connected
again to the power supply.
•The wear parts (filter materials, light tubes, quartz sleeves, seals) are usually available in stock
at WilTec Wildanger Technik GmbH –www.wiltec.de.
CPF-2500-5000-10000-15000-20000-30000
With this mode, you only have to loosen 4 screws to take off the UV unit.
WARNING:
•For all maintenance work the UVC has to be disconnected from the power supply!
•The filter can be put into operation only if the UVC is FULLY assembled!
•Never tinker with the running UVC lamp!
•The UVC must NOT be carried by the cable!
•Always place the UVC outside the pond (not in the water)!
•Remove the UVC by frosty weather!
