Automatic device (Pressure switch)
o While using the automatic pump, in case it still operates after turning off the
water tap, lower down power cut-off pressure of the pressure switch on the
premise of pipeline without leakage, namely, rotate the variable screw nut II
in counter clockwise direction (-) to acquire lower closing pressure.
In case the pump is often enabled when the water tap is turned off (sometimes
o
it is turned on and sometimes it is turned off), check whether pipeline and the
bottom valve have leakages and pressure vessel pressure is normal,
eliminate timely if any.
In case the pressure switch is alternately turned on and turned off (frequent start)
o
after turning on the water tap, increase power cut-off pressure of the pressure
switch, namely, rotate the variable screw nut I in clockwise direction to acquire
higher opening pressure.
