UV-C UNIT
The built-in UV-C Unit 18 Watt supplied along is able to keep 10.000 litres of pond
water crystal clear. The unit can easily be placed in the holder. The UV-C lamp re-
moves floating algae (green water) and it is an excellent remedy in the fight against
bacterial infections. The Cross-Flow Swirl has 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. The unit has a transparent
screw cap for safe inspection of the lamp. See also the UV-C Unit instructions.
Besides the filter materials referred to, Velda has filter media with specific properties:
l Norit high active filter carbon to remove colourings and odours.
l Ammonium filter medium to absorb ammonium and ammonia.
ITEMS FOR SPECIAL ATTENTION
If water should leak from the top of the Cross-Flow Swirl, this can be caused by pres-
sure building up inside the filter, as a result of which the water can not flow freely.
Below you find some items which will help you finding out why the filter is leaking:
l Place the filter above the level of the pond water and horizontally on a flat soil.
l Place the cassettes and filter materials in accordance with the instructions for use.
l Inspect whether the filter material is blocked up or polluted. Especially if the
pond water was/is considerably green, the filter material can quickly get polluted
and it has to be rinsed then.
l The outflow orifice of the filter (50 mm) may not be reduced. The water must be
able to flow out freely.
l The maximum flow capacity of the filter is 5000 l/h. If the net output of the pump
is larger, the water will flow over the edge.
l Avoid back pressure. The water may not be elevated after the filter.
l Inspect whether the rubber ring in the groove of the cover has been applied correctly.
As Velda can not exercise any influence on a proper installation as well as the
functioning of the filter on the spot, Velda can not be held liable for any leakage,
as a result of which the pond will loose water.
GUARANTEE
Velda guarantees the correct functioning of the filter for a period of 24 months after
purchase. See the conditions and stipulations on the enclosed guarantee card.
