Page 35: Avoiding Siphoning
After the filter unit is switched off, the height difference/primary pressure can cause flow to occur both in the feed direction and against the feed direction and the fluid can leak uncontrollably. MoWa OLFP-1-T002 4469047 en-us lq 35 / 64... -
Page 36: Observing/Calculating Pressure Loss
– Avoid constrictions in the connected hoses. This reduces the power and increases the risk of cavitation. – Note that the nominal size of the connected hose/piping must correspond to the cross-section of the connection thread. 36 / 64 MoWa OLFP-1-T002 4469047 en-us lq... - Page 37 – Make sure that the connection hoses/piping (suction side/ pressure side) do not cause any tension or vibrations to be carried over to the filter unit.
