Adjusting the level detection device
Setting the level detection device correctly is crucial for problem-free operation.
Gravity fed system
Adjust the level detection device to the water level in the container to ensure the optimum operation of
the filter system. A 10 mm open jaw spanner is required for this adjustment.
How to proceed:
11.
P
1. Remove the container cover.
2. Switch off the filter pumps and check the water level.
Ensure that the water level reaches the height of the maximum mark on the inside wall of the
−
container.
Adjust the water level in the pond if necessary.
−
3. Switch off the mains voltage (ensure that the control system is isolated).
4. Loosen both screws of the level detection device so that it can be easily moved.
5. Fit the container cover.
6. Switch on the control system and filter pumps and start a cleaning cycle.
7. Isolate the control system and remove the container cover.
8. Move the level detection device until the marking on the housing coincides with the water level.
9. Tighten the two screws of the level detection device.
10. Replace the container cover and switch on the control system.
Note:
Perform the setting quickly following the cleaning cycle. The screen elements continually trap dirt
►
particles. This causes the water level to drop in the container.
Subsequently perform another cleaning cycle and check the setting. Correct the setting if necessary.
►
Check the setting again when the desired water quality has been reached.

Pump fed system
Q
In the case of pump fed systems, the water level in the filter system is independent of the water level in
the pond. The water level in the filter system is dependent upon the circulation capacity. Therefore it
may be necessary to adjust the level detection device.
The level detection device can be fitted in four positions. This information is based on the assumption
that 2x DN 110 outlets are connected to the last filter module to return the water to the pond.
Position 1 or 2: Suitable for circulation capacities smaller than 22000 l/h and short automatic
►
cleaning intervals.
Position 3: Suitable for circulation capacities of up to 22000 l/h (delivery status).
►
Position 4: Suitable for circulation capacities greater than 22000 l/h.

How to proceed:
11.
1. Undo both lock nuts. Remove nuts and Allen screws.
2. Move the level detection device according to the hole pattern and fix in place with Allen screws and
lock nuts. Tighten both nuts.
