Cleaning foam filters

Cleaning intervals depend on the degree of soiling of the foam filters. A higher water level in the soiling
indicator (Figure C, 12) in the inner cover signals that the foam filter cleaning capacity has decreased.
Cleaning is due from a degree of soiling of 75 % or in the event of an overflow at the latest.
How to clean the foam filters (Fig. H, I, J)
1. Open lid (1) with the rotary handle (2) and remove lid from the container (3).
2. Close the stop valve (17) by pulling it up.
Pond water no longer flows into the container.

Note: Water will spurt out of the air intake socket when closing the stop valve (17).

3. Pull foam filters (13) up several times.
The foam filters will be compressed. The soiling will be washed out.

4. Press the PUMP key (C4) on the controller (15) for longer than 10 seconds.
The LED (C2) is lit green. All of the dirty water in the container will be pumped out.

5. Open the stop valve (17) by pressing it down.
The container fills up with pond water again.

Repeat the cleaning cycle if the foam filters are heavily soiled.

Remove and separate the cleaning components from each other

For cleaning and maintenance of the cleaning components of the dirty water pump (14) and the UVC
clarifying unit (16) it is necessary to take both out of the container. The controller (15) is fitted to the UVC
clarifying unit. The cleaning components are not permanently connected to the inner cover (47) but rest
in the guides of the inner cover (47) or of the stop valve (17) respectively.
This is how to remove the cleaning components (Figure K)
1. Open lid (1) with the rotary handle (2) and remove lid from the container (3) (Figure H).
2. Close the stop valve (17) by pulling it up.
Pond water no longer flows into the container.

Note: Water will spurt out of the air intake socket when closing the stop valve.

3. Lift the cleaning components of the dirty water pump (14) and of the UVC clarifying unit (16) out of the
inner cover (47) as one unit.
This is now the cleaning components and the controller are separated from one another (Figure
L)
1. Keep the engagement hook (30) on the UVC clarifying unit (16) pressed.
2. Remove the controller (15) from the UVC clarifying unit by applying force.
3. Pull the connection cable (28) of the dirty water pump off the controller (15) by applying force.
4. Plug in the silicone caps to protect the open sockets.
5. Reassemble the cleaning components and the controller in the reverse order (Figure M).
When assembling the controller and the UVC clarifying unit, ensure that the arrows on both

components point to one another.
During assembly, check the seating of the O rings (29) at the connection points of the controller and of
the UVC clarifying unit! Clean the O rings (29) as required. The electrical contacts will corrode if the O
rings are missing or incorrectly seated. This will lead to irreparable damage to the components!
