VERSION 1.01 01/2022 PRESSURE FILTER
FURTHER NOTES:
• Before each commissioning of the filter, the seals and connections must be checked for correct assembly.
• Pond pressure filters are only suitable for filtration of water with impurities that are typical for pond water.
• Do not expose the filter to direct sunlight for long periods.
• In the event of frost, the filter must be completely emptied, if necessary dug up and stored in a dry, frost-free place.
• After any work where the lid has to be removed, make sure the sealing ring is in place when replacing the lid! Place the
clamping ring around the lid, press the lid down and close the clamp.
Pressure filters of the GPF-2500-5000-10000-15000-20000-30000 series have a quick cleaning function by means of a handle.
Instead of the push button described above, you turn the handle until the filter sponges are clean.
We recommend changing both lter material and lamps annually to ensure proper lter operation.
When using the filter normally, the "drain connection" (C) should be sealed with the supplied
end cap with seal and sight glass to prevent dripping from the connection. The pressure filter models of the GPF-2500-5000-
10000- 15000-20000-30000 series have a hose tail with integrated ball valve to close the connection.
REPLACING THE BULB
If the number of algae increases, this may indicate that the UV-C lamp needs to be replaced. You can see whether the lamp is lit
by the UV indicator. Always replace the lamp after one season!
• Disconnect the UV lamp and the pump from the power supply before replacing them.
• Loosen the 4 screws of the UV unit from the filter cover.
• Carefully remove the UV unit.
• After the UV unit has cooled down and dried, grasp the underside of the lamp (not the glass!)
with a soft cloth and carefully pull it out of the socket.
• Hold the new lamp at its base with a soft cloth and carefully insert it into the socket.
• Now the quartz glass in which the lamp is located must be cleaned. Dissolve the deposited
lime scale with suitable agents (coffee machine cleaner or water descaler such as citric
acid) while heating. Afterwards, make sure you remove all traces of the cleaning agent from
the quartz glass.
• After flushing, reassemble all components in reverse order. Reconnect the pump and the unit to the mains.
• The UV-C device must be disconnected from the mains before any maintenance work is carried out!
• Start-up only if the UV-C system is FULLY assembled!
• DO NOT make any changes to a running UV-C unit!
• The UV-C device must NOT be carried by the cable!
• Always place the UV-C device outside the pond (never in the water)!
• If there is frost, you should remove the UV-C device!
