5.8 Backwashing the filter material

Avoid carrying sand abrasion into the basin when you first start it up. So, the filter filling must be
backwashed for this purpose. The backwash process should last about 4 minutes at start-up.
Rinsing equalises the filter bed and rinses any abrasive particles or dirt particles into the sewer.
To select another function of the backwash valve:
Always press the operating lever down first and then move it. (Only when the pump is switched off)
