Some specialists recommend regular weekly filter rinsing. If you use any coagulating agents, make it less frequent. In practice any filter should be provided with a manometer reading the pressure. Until the hand is within the green space filter rinsing is not necessary. As a rule after 2-3 weeks the hand enters the yellow space and then rinsing should be done.
Caution! Don’t allow the hand to reach the red.

Other positions of the multi-port valve:

• waste (spulen) – when the pool is cleaned or emptied,
• recirculate (zirkulieren) – water circulates avoiding the filter,
• closed (geschlossen) – to completely shut off the circulation in the pool and the filter.
