This UV-C device ensures a clear pond with healthy fish. The pond water is pumped through the UV-C device,
where it is exposed to UV-C radiation at a wavelength of 254 nanometres. The radiation is produced by a
special light, which ensures that germs and bacteria are not given the opportunity to develop. The water
is exposed to an extra long radiation time, thanks to the length of the device. Furthermore, the housing
reflects the UV-C radiation, which increases efficiency by up to 35%. The housing of the Flex UV-C has an inlet/
outlet for water on 4 sides, enabling you to install the UV-C device onto your pipe system any way you like.
During the frost-free period the device is used 24 hours a day, so as to achieve an optimal result. Thanks to
this UV-C device your pond water will become clear within 14 days and your fish will be in peak condition.
EARTHING INSTALLATION (DRAWING 1)
1. Pull the cable (2) through the strain relief (4) before fitting the synthetic strain relief (4) onto the earth
bolt (1). Position the strain relief (4) at approximately 10 cm from the eye (2) of the earth cable.
2. Place the eye (2) of the cable onto the earth bolt that is fitted to the housing.
3. Then place a toothed lock washer (3).
4. Fit the strain relief (4), creating a loop of Ø5 cm.
5. Finally place the second toothed lock washer (5) and the lock nut (6) onto the earth bolt.
6. Once the parts have been placed onto the earth bolt in the correct sequence,
they can be tightened with a spanner or a ring spanner number 8.
INSTALLATION (DRAWING 2)
This device must never be put in the water. The ideal location to install your device is
immediately behind the filter. See schematic representation in the front of the manual
Always install outside the pond. Ensure that there is always water flowing through the
