Operating instructions
3.4 Temperature control
Cold water mode 34 - 104°F
Hot water mode 104 - 176°F
Steam mode 302°F
Choose the desired temperature with the control knob (16).
Note: If the machine is put away immediately after hot water or steam operation, it should be cooled in
“cold water” operation until the temperature is below 120°F. This will take approximately 2 minutes.
IMPORTANT (only 30HA Master) : Adjustment to temperatures above 176°F should be made with the
trigger released. When choosing temperatures above 176°F (steam operation) the water volume is auto-
matically reduced . Then full water volume for cold water or hot water operation cannot be obtained until the
temperature of the outlet water has fallen below 176°F. Once the temperature is below 176°F, release and
squeeze the trigger to return to full water volume again. The cooling period, from max. temperature (302°F)
to full water volume is approximately 1 minute.
3.5 Spray lance, pressure regulation, how to use detergents
Turn pressure reducing valve:
Clockwise (B): for high pressure
Counter clockwise (A): for low pressure
and detergent application
The spray lance features a high pressure nozzle and a low pressure nozzle. When the pressure reducing
valve (1) is completely closed (clockwise - B), only the high pressure nozzle is used and you’re in the “
high
pressure mode ”. When the pressure reducing valve is open (counter clockwise - A), both nozzles are
used and you’re in the “ low pressure mode ” (where you can also add detergents). The pressure may be
infinitely varied between “full” and “low”.
