Changing the light tube
If the algae proliferate, it is necessary to check the correct the functioning of the UV-C lamp. You re -
cognise on the UV-indicator if the lamp lights at all. Change it every season.

Before changing the UV lamp disconnect the pump.
Release the 8 screws of the UV unit from the filter lid.
Carefully remove the UV lamp.
After the UV unit has cooled down and dried up, grab the base of the light tube (not the glass!)
with a soft cloth and pull it cautiously out of its socket.
Now the quartz glass inside which the light bulb is placed must be cleaned. For this purpose
the lime has to be dissolved under heating with appropriate agents (coffee machine or kettle
descaler like citric acid). After this rinse the quartz glass from residues remaining from the
cleaning agents.
After rinsing all parts are reassembled in reverse order. The pump and the device are connec-
ted again to the power supply.
The wear parts (filter materials, light tubes, quartz sleeves, seals) are usually available in
stock at

With this mode, you only have to loosen 4 screws to take off the UV unit.
