Operating instructions GB
3.4 Temperature control
Cold water mode 0 - 40°C
Hot water mode 40 - 80°C
Steam mode 150°C
Choose the required temperature by means of the control knob (16).
If the machine is put away immediately after hot water or steam operation, it should be cooled off at first by
"cold water operation" until the temperature is below 50°C. The cooling period from 80°C to 50°C is approx.
2 min. by cold water operation.
IMPORTANT (only 30HA MASTER): Adjustment at temperatures above 80°C should be made with re-
leased spray handle.
When choosing temperatures above 80°C (steam operation) the water volume is automatically reduced.
Then full water volume by cold water and hot water operation respectively cannot be obtained until the
temperature of the outlet water has fallen below 80°C. Upon that release the spray handle to have full
water volume again. The cooling period, from max. temperature (150°C) to full water volume is approxi-
mately 1 minute.
Direction of rotation of the motor
The direction of rotation of the motor should be correct in order to ensure air
supply for the boiler. If the direction of rotation is wrong (no airflow from the
chimney and thus black smoke from the boiler by hot water operation),
please refer to section »7.0 Troubleshooting and correction - phase se-
quence«.
3.5 Spray lance, pressure regulation, how to use detergents
Turn pressure reducing valve:
Clockwise (B): high pressure
Counter clockwise (A): low pressure /
addition of detergents
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 clockwise - A) both spray
lances are used - low pressure mode / possibility of adding detergents. The pressure may be regulated
between these positions.
