Water is fed into the float container via the water filter.
When connected to the mains, the operation takes place
with external water supply, as an alternative, both tanks
can be filled and the operation takes place independently.
The feed to the HP pump takes place by means of the cou-
pled filling levels between the tanks and the float container
until there is no more water in the float container.
The water is lead through a heat exchanger that is con-
nected to the cooling circuit of the motor. This way, the wa-
ter is already heated by approx. 10K and the motor is
cooled.
Via a fine filter, the water reaches the high-pressure pump
that is driven by the diesel engine via an intermediate gear.
With systems with detergent, detergent is added on the
suction side of the pump.
Through the booster heater and via the high-pressure
hose the water reaches the work machine. In case of warm
water operation, the water is softened in the float contain-
er.
If there is no water removal at the gun, the water in the cir-
cuit is lead through the overflow valve back to the float con-
tainer.
A temperature sensor in the float container checks the wa-
ter temperature. If the temperature is too high, the device
stops automatically as the water cooling of the motor de-
pends on it.
The motor itself is equipped with the relevant sensor tech-
nology concerning the oil pressure an coolant tempera-
ture.
