Pressure/ quantity regulation at the
hand spray gun
Set thermostat to max. 98 °C.
Set the operating pressure on the pump
unit to the maximum value.
Set the working pressure and feed
quantity by turning (steplessly) the
pressure/quantity regulation mecha-
nism at the hand spray gun (+/-).
Danger
When adjusting the pressure/quantity regu-
lation, make sure that the screw connection
of the spray lance does not become loose.
Note: For long term work with low pres-
sure, set pressure at the pump unit.
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.
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:
–

Cleaning
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.
Note: The temperature can be regulated
up to 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 temperature regulator 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:
