General notes
Safety features
Overflow valve with two pressure
switches
—
When reducing water volume at pump
head or with the servopress control, the
overflow valve will open and part of the
water will flow back to the pump suction
side.
—
If the handgun is closed off so that all
the water flows back to the pump suction
side, the pressure switch at the overflow
valve turns off the pump.
—
Reopening the handgun causes the
pressure switch at the cylinder head to
switch the pump back on again.
The overflow valve is set at the factory and
lead-sealed. Adjustment can only be made
by After-Sales Service.

The safety valve opens if the overflow
valve or pressure switch is defective.
The safety valve is set at the factory and
