5. The filter will now be rinsed clean. As soon as only clean water
can be seen through the transparent spiral stepped hose adapter
at the cleaning connection, pull the function switch up slightly
and turn anti-clockwise until it clicks into the "Filter" position.
6. Screw the sealing cap with the inserted flat seal tight onto the
cleaning connection or the drainage hose that is connected to
the cleaning connection.
7. The filter is now operational again. Check the water flow into
the pond at the green flow vane.
Washing the filter sponges
If the water flow is too small due to dirty filter sponges and cannot
be improved through cleaning with the handle function, then the
filter sponges must be washed or replaced.
Note: Do not use any chemical cleaning agents so as not to kill
off the microorganisms in the filter sponges.
1. Disconnect the mains plug of the Filtoclear UVC.
2. Switch off the pump and ensure that it cannot be switched on
unintentionally.
3. Remove all hoses by unscrewing the union nuts.
4. Remove the tension ring. To do this, pull back the safety latch,
push in the fastening hook and open the tension ring.
5. Lift off the lid with the filter sponge assembly. Place the lid
upside down on another clean surface. The filter sponges are
lying with the filter plate facing up.
Wear marking:
The filter sponges are pre-stressed. The filter sponges can
fall apart due to the mechanical strain and due to normal
ageing. This can result in a short-circuit in the filter.
To check the filter sponges, they must lie on top of each
other on the lower filter plate without any "air gaps". The
filter sponges must be replaced if the wear marking on the
upper plate is completely visible (see illustrations)
6. Remove upper filter plate by unscrewing the two screws.
7. Pull off the filter sponges and clean under flowing water. Give
the filter sponges a good squeeze.
