5.1.2
Setting the level detection device
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 three positions. This information is based on the as-
sumption that at least one DN 110 drain is used as a return line to the pond on the pump-fed
Premium XL drain module for each 12500 l of flow volume.
Position 1: For high flow volumes of >45000 l/h and/or severely contaminated ponds.
•
Position 2: For normal flow volumes of 30000 ... 45000 l/h (condition on delivery).
•
Position 3: For low flow volumes of <30000 l/h (lower rinsing frequency).

How to proceed:
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.

Order of starting up steps
How to proceed:
B
1. Close the slide valve for the dirt outlet at the bottom of the container.
2. Check that the entire filter system (pipes and hoses) is complete.
3. Remove the container cover.
4. Manually turn the filter drum for one whole rotation to ensure unobstructed movement.
5. Open the slide valve at the inlet and outlet, if applicable, to fill the filter system with water.
6. Fill the pond until the maximum water level is reached.
7. Check the water level in the drum filter module. Refer to the sticker with level markings on
the inside wall of the container.
– Ideal water level: 120 mm below the top edge of the container
– Permissible tolerance: -20 mm (140 mm below the top edge of the container)
– Correct the installation if the minimum water level is not reached.
8. Check all pipes, hoses and their connections for leaks.
– Expansion seals may leak initially until they have fully expanded on contact with water.
9. Fit the container cover.
– The filter drum is stopped for safety reasons if the filter cover is lifted.
10. Switch on the control system and perform any necessary adjustments. (→ Operation)
11. Switch on the filter pumps and, if necessary, the UVC clarifiers in the ProfiClear Premium XL
drain module.
12. Adjust the level detection device to the water level in the filter system. (→ Setting the level
detection device)
13. If necessary, adjust the filter pump status detection. (→ Setting the filter pump status detec-
tion)
