Your pressure switch is factory set and should not normally require adjustment. However, if
adjustment is required due to the power supply voltage varying from the previous setting,
either because of battery drainage or higher voltage being supplied when the battery charger is
operating or in the event that your pump doesn’t switch off when you close the taps or pulses on
and off rapidly when the taps are fully open.
You should follow the below guidelines to re-adjust the pressure switch setting.
