Set working pressure and flow rate
Pressure/quantity regulation of the
pump unit
 Turn the regulation spindle in a clock-
wise direction: Increase working pres-
sure (MAX).
 Turn the regulation spindle in an anti-
clockwise direction: Reduce working
pressure (MIN).
Operation with detergent
For considerate treatment of the envi-
–
ronment use detergent economically.
The detergent must be suitable for the
–
surface to be cleaned.
 With support of the detergent dose
valve set detergent concentration as
determined by the manufacturer.
Note: Recommended values at the control
panel at maximum working pressure.
Note: If detergent is be suctioned from an
external container, route the detergent suc-
tion hose through the recess to the outside.
Cleaning
 Set pressure/temperature and deter-
gent concentration according to the sur-
face to be cleaned.
Note: To prevent damage due to too much
pressure, always position high pressure ray
first from a greater distance towards object
to be cleaned.
Recommended cleaning method
Loosen the dirt:
–
 Spray detergent economically and let it
work for 1...5 minutes but do not let it
dry up.
Remove the dirt:
–
 Spray off loosened dirt with the high-
pressure jet.
Operating with cold water
Removal of light contaminations and clear
rinse, i.e.: Gardening tools, terrace, tools, etc.
 Set operating pressure according to
need.
The appliance works in the most economi-
cal temperature range (max. 60°C).
Operating with hot water/steam
We recommend the following cleaning tem-
peratures:
Light contaminations
–
30-50 °C
Contaminations containing protein, i.e.
–
in the food processing industry
max. 60 °C
Vehicle cleaning, machine cleaning
–
60-90 °C
De-preserve, contaminations contain-
–
ing strong fat contents
100-110 °C
De-frosting of surcharge substances,
–
partially facade cleaning
up to 140 °C
Operating with hot water
Danger
Scalding danger!
 Set device switch to desired temperature.
Operating with steam
Danger
Scalding danger! The operating pressure
must not exceed 3,2 MPa (32 bar) when
operating with temperatures above 98 °C.
Therefore the following measures must
definitely be performed:
 Replace high pressure nozzle (stain-
less steel) with steam nozzle (brass,
order see specification).
 Set the operating pressure on the pump
unit to the minimum value.
 Set device switch to min. 100 °C.
After operation with detergent
 Set dosing value for detergent to "0".
 Set the appliance switch to "1" (opera-
tion with cold water).
 Open the hand spray gun and rinse the
appliance for at least 1 minute.
