Commissioning of the pressure filter
Before commissioning make sure that all cables and hose connections are installed correctly. The
switch must be set to “filter function.” Before the very 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 watertight.
3. Turn on the pressure filter.
4. The filter system with the integrated UV lamp must permanently operate 24 hours a day.
5. The UV lamp should be replaced after an operational period of 8000 hours in order to guaran-
tee an optimal efficiency of the system.
6. The filter system should be cleaned regularly.
Attention:
In case of the first/a new installation, the cleaning capacity will be fully reached
only after a few weeks, after the necessary microorganisms have grown. This will be espe-
cially the case with an ambient temperature above +10
℃
.
Caution:
The UVC lamp must not be operated as long as it is not flooded by water.
Never use the UVC unit if the lamp or a connection is damaged.
Never use the UVC filter if there are people in the water.
The installed temperature sensor inside the UVC filter switches off the UVC lamp automatic-
ally 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. Before use
rinse them carefully with pond water.
Installation and structure
Filter media
The bio filter balls (depending on the model) are placed on the filter bottom, the grate with the protect-
ive tube for the UVC unit is inserted above. Place the filter sponges on it, 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 working pressure of 0.5 bar. The power supply has to be equipped with a
fault current protection switch that must not exceed 30 mA.
Installing the hose connectors/nozzles
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 closing caps on the clean stub.
