Connecting the pump

There are two connections on the filter lid, both fitted with a hose socket. Connect the pump to the

outermost socket. Use a hose with a diameter that corresponds with the diameter of the pump out-

let. Saw off the unused diameters on the hose socket. The socket in the center of the lid is the

discharge to the pond. Connect an appropriately sized hose to the largest socket diameter. Saw off

the other diameters. The use of hose clips is recommended to prevent the hoses slipping off.

The maximum pump output for the VEX-100 is 3,000 l/h.

The maximum pump output for the VEX-200 is 6,000 l/h.

The maximum pump output for the VEX-300 is 8,000 l/h.

After the filter has been positioned correctly and the pump has been connected, the built-in UV-C

Unit can be switched on.

The UV-C Unit

The VEX Pond Filters are supplied complete with a built-in UV-C Unit; the VEX-100 with a 7 Watt

Unit, the VEX-200 with a 9 Watt Unit and the VEX-300 with an 11 Watt Unit. The UV-C PL lamps

have a service life of approx. 7,000 hours. This corresponds with a seasonal use from March to

November. The UV-C lamps can be easily replaced by unscrewing the screws in the spherical part

of the lid. It is recommended that a new UV-C PL lamp be fitted at the start of the season. The

advantages of UV-C are meanwhile widely known; it clarifies green water and is an excellent aid

in combating bacterial infections. The VEX filters have a separate chamber, which prevents the

UV-C radiation coming into contact with the filter materials. So the micro-organisms in the filter

material are not harmed.

MAINTENANCE

Maintenance of the VEX filters is extremely simple. While the dirt indicator remains green, water

flow through the filter is uninhibited. When the indicator turns red, it means the filter material is

clogging up, so reducing the filter volume. By attaching the pump to the outflow socket, most of the

dirt will now be back-flushed out of the filter. If following this action the dirt indicator is still red, the

filter materials will need to be rinsed clean by hand under running water. If due to circumstances

the water supply to the filter is cut off for four hours or more, the filter material should first be rinsed

before recommencing filtration. This prevents micro-organisms killed by a lack of oxygen being

flushed into the pond.

GUARANTEE

Vijvertechniek Nederland warrants performance as described above if the filter is correctly assem-

bled and correctly maintained. The warranty period for these pond filters is therefore two years.

The warranty does not cover the rubber sealing ring or the clamp on the filter, nor the UV-C PL

lamp and filter materials. Also excluded from warranty cover is the use of the filter in combination

with oil, petrol or lubricants. Frost damage is not covered either. Claims under the warranty will on-

ly be considered if a dated purchase receipt can be produced. See enclosed warranty card.
