Start-up and maintenance
6.1 Start-up
Before start-up, the sieve surface must be cleaned thoroughly using a brush and a fat-dissolving cleaning
agent. Alternatively, it may also be cleaned using a fat-dissolving cleaning agent and a strong jet of water
(high-pressure cleaner 40°C (104° F) - max. 60°C (140° F)). Dirt that entered the filter housing during
assembly must be removed.
6.2 Maintenance
The entire system must be checked for tightness, cleanliness and stability at least once every three
months. The filter insert must be cleaned approx. every three months (or more often depending on the
amount of dirt).
6.3 Cleaning
If the filter fabric becomes clogged due to a large amount of dirt, and cleaning is no longer possible using
the filter cleaning unit, the sieve insert is to be disassembled and cleaned as described below.

Remove the filter insert
- Remove the cover of the pilot shaft/cistern

- Pull the sieve insert upwards to remove it
Clean the filter fabric
- Scrub the sieve surface thoroughly using a brush and a fat-dissolving cleaning agent
- Clean with a strong jet of water (high-pressure cleaner 40°C (104° F) - max. 60°C (140° F))
- Remove all dirt from the filter insert
Insert the filter insert
- Insert the sieve insert in the filter housing
- Check the surrounding seal for proper positioning
- Fit the cover on the filter housing
- Connect the filter cleaning unit
- Fit the cover back on the pilot shaft/cistern
