least 10 A.
Warning:
•The UVC filter should be placed in such a way so that the water cannot reach it. The distance
between the pond edge and the filter should reach at least 2 m. The UV lamp cannot be oper-
ated under water.
•The power supply of the UVC filters must not be turned on before the water circulation has been
carried out.
•Please position the UVC filter on a safe and stable place because the pond filter light tube (the
tube that conveys the light) is made of quartz glass that can burn easily.
•Do not turn the power on before all the component parts of the device are installed.
•If the quartz glass tube or the upper part of the UVC filter is damaged, the pond pressure filter
cannot be used.

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
without water flow or

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.
