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.
