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.

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).
