INSTRUCTIONS FOR UV-C UNIT 9 / 18 / 36 / 55 WATT

Before installing the UV-C unit and putting it to use, carefully read the present user instructions
and safety regulations. The Velda UV-C units are specially designed for use in filter systems and
meant to filter pond water with the help of UV-C radiation. It is composed of the following parts:
1. Quartz glass
2. PL UV-C lamp (18, 36 and 55 Watt with spacer)
3. Fitting with cable and ballast
4. Transparent screw cap to monitor the PL UV-C lamp safely. Contact of
your eyes and skin with the harmful UV-C radiation will be prevented.

APPLICATION

UV-C equipment has been used for a long period of time to keep the water of aquaria and ponds
free from floating algae and to decrease the number of germs. UV-C filtration therefore guarantees
that you will obtain crystal clear water and a healthy water environment for both fish and water
plants. Its action is based on ultraviolet radiation, which attacks the cells of animal and vegetable
organisms. As the water to be filtered is directly passed along the quartz glass in a thin layer, the
action is optimum. We advise you to let the UV-C filter burn continuously during the pond season.
In the winter season (from December up to and including mid-March) you should keep the appara-
tus switched off and store it in a dry place to protect it from freezing.

INSTALLATION

The UV-C Unit 9 Watt is used in the Cross-Flow Biofill and Clear Control 25.

These Velda filters have a separate compartment, meaning that the UV-C radiation does not
come in contact with the filter material. Therefore, the micro-organisms in the filter material are
not damaged.

Install the splashproof unit in the special compartment of the filter at the place

of the screw cap. Place the ballast in an area protected against rain and sun.

the plastic cover from the PL UV-C lamp. The spacer protects the UV-C lamp during use (18, 36
