Safety devices

CAUTION
Missing or modified safety devices are provided for your own protection. Never modify or bypass safety devices. The safety devices are set and sealed by the manufacturer. Adjustments are performed only by customer service.

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 released, 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.

Water connection

Connection to a water line
WARNING
The return flow of dirty water into the drinking water network.

Health risk Observe the regulations of your water supply company. According to applicable regulations, the device must never be used with the drinking water network without a system separator. Use a system separator fromKÄRCHER or a system separator as per EN 12729Type BA. Water that has flowed through a system separator is classified as undrinkable. Always connect the system separator to the water supply and never directly to the water connection on the device.

Check the supply pressure, supply temperature and supply volume of the water supply (see chapter Technical data).
Connect the system separator to the water connection of the device using a water supply hose (for the requirements placed on the water supply hose see chapter Technical data).
Open the water inlet.

Sucking water from a container

Screw the suction hose with filter onto the water connection (for the order number see chapter Technical data).
Vent the device (see chapter Vent the device).

Vent the device

Unscrew the high-pressure nozzle from the spray lance.
Allow the device to run until the escaping water is free of air bubbles.
In the case of venting problems, allow the device to run for 10 seconds and then switch it off. Repeat the procedure several times.
