Overflow valve with pressure switch
When the water quantity is reduced via the pressure/
quantity control on the trigger gun, the overflow valve
opens and part of the water flows back to the suction
side of the pump.
When the trigger on the high-pressure gun is release,
the pressure switch switches off the high-pressure
pump and the high-pressure jet stops.
The pump switches on again when the trigger is pulled.

The safety valve opens when the permissible operating
pressure is exceeded and the water flows back to the
suction side of the pump.

arator is classified as undrinkable. Always connect the
system separator to the water supply and never directly
to the water connection on the device.
1. Check the feed pressure, input temperature and in-
put amount of the water supply. See the "Technical
data" section for the requirements.
2. Connect the system separator and water connection
of the device with a hose (minimum length 7.5 m,
minimum diameter 1").
The supply hose is not included in the scope of de-
livery.
