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

1. Screw the suction hose with filter onto the water
connection (for the order number see chapter Tech-
nical data).
2. Vent the device (see chapter Vent the device).
Vent the device
1. Unscrew the high-pressure nozzle from the spray
lance.
2. Allow the device to run until the escaping water is

3. In the case of venting problems, allow the device to
run for 10 seconds and then switch it off. Repeat the
procedure several times.
4. Switch off the device.
5. Screw the high-pressure nozzle onto the spray
lance.
