3.5 Spray lance, pressure regulation
Turn pressure reducing valve:
Clockwise (B): high pressure
Counter clockwise (A): low pressure
The spray lance features 2 nozzles, a high pressure nozzle and a low pressure nozzle. When the
pressure reducing valve (1) is completely closed (turned clockwise - B), only the high pressure nozzle
is used - high pressure mode. When the pressure reducing valve is quite open (turned counter clock-
wise - A) both spray lances are used - low pressure mode. The pressure may be regulated between
these positions.
3.6 End of operation
1. Dismounting of high pressure hose
Danger of scalding!
Never dismount the high pressure hose
when the water temperature is above
50°C.
Turn the temperature control (1) to position „cold water“ and activate the spray handle until the tempe-
rature (2) is below 50°C. Then turn off the water supply and stop the machine by pressing stop button
(3) marked - 0 -. Now the high pressure hose can be detached.
2. Automatic stop
When the machine is in operation and the spray handle inactivated, the machine will stop after approxi-
mately 40 sec. The signal will appear on the digital display of the control panel meaning that the
machine can be restarted by activating the spray handle.
3. Stop in the event of faults
If the machine stops in the event of faults, the fault code will be shown on the digital display of
the control panel. The fault code refers to a fault, which is described in section „7.0 Trouble
shooting chart“. This section is referred to in general in the event of an unintentional stop of
operation.
