Cleaning and maintenance
Beware!
Always pull the mains power plug of the pump before cleaning and maintenance!
The device should be cleaned as needed
– see waste display
(1).
1. Turn off the pump and the UV-clarifier.
2. Remove the filter sponges.
3. The sponges can be cleaned and squeezed out in clear
water. You can also use pond water.
4. Never use any detergent or soap as those will destroy the
bacteria inside the filter sponges.
5. Clean the filter tank with clear water, too.
6. It is not necessary to renew or clean all filter sponges at the
same time. If you just clean/renew a part of them, the im-
portant nitrifying filter bacteria are saved to a large extent and
need not to grow completely.
7 In case the base of the filter is too contaminated, it is rec-
ommended to drain the water completely from the filter.
8. After cleaning the filter, it is reinstalled as described.
At temperatures below 8
℃
or higher than 40
℃
, the device must not be operated! Therefore, empty the
filter and clean the device thoroughly. Remove all filter materials in order to dry them. Keep the filter
materials in a dry, frost-free place during the winter. Cover the filter housing so that no rain water can
enter. Empty all hoses, pipelines and connectors to the extent possible.
Before starting-up the filter again, install it again with the open side towards the exit.
