Operation
5.3
Differential pressure control
The selector shaft of the differential pres-
sure switch is set at the adjusting screw.
The value can be adjusted with a screw-
driver between 0.9 psi (6.2 kPa) and 9 psi
(62 kPa), see scale.
If the value is set too high, dirt may accumu-
late with low flow rate. During times of
higher water removal the differential pres-
sure will increase to an extent that damages
at the screen may occur.
5.4
