Pressure adjustment screw.
Setting
The pressure switch uses a large compression spring to activate under pressure, the desired
switching pressure is selected via the pressure adjustment screw at the top of the switch.
On the side window are markings from 4 to 12
(10x number shown for meters of head pressure)
to show where
the pressure is set, a red tab inside moves up or down as the top screw is adjusted.
A right turn on the screw raises the pressure, a left turn lowers the pressure.
The pressure switch must be set between 5 and 10 meters above your operating head pressure
(TDH).
