Safety features
Overflow valve with pressure
switch
On reducing the flow rate with the pressure
and flow control, the relief valve opens and
part of the water runs back to the suction side
of the pump.
If the lever of the hand-held spray gun is re-
leased, the pressure switch switches the
pump off. If the lever is retracted, the pressure
switch switches the pump on again.
Safety valve
The safety valve opens when the admissible
operating excess pressure is exceeded; the
water flows back to the pump suction side.
Overflow valve, pressure switch and safety
valve are present in the factory and are
sealed.
Adjustments are made only by Customer
Service.
