STOPPING THE M20 SNOW MACHINE FROM THE “STATUS” DATA FIELD
Also when stopping the snow machine, all steps that the machine is carrying out can be supervised from the
“Status” data field.
If the STOP key is pressed, the following appears on the display (illustration 15):

The next step is closing the valves and the hydrant. When an automatic hydrant has been installed, this will be
closed by the snow machine itself, otherwise the snow machine waits until the hydrant will be closed manually by
the user (illustration 16).

ATTENTION
When the manual hydrant has not been closed within a period of 60 minutes, then an error report appears on the
display and the machine keeps running, as long as the water pressure does not sink to under 2 bar
(The automatic hydrant needs a shorter switch off time.)
With the closing of the hydrants, all valves will be closed at the same time. In the case of jet ring pressure of more
than 2 bar, all valves will be opened, so as to improve emptying.
After this phase the turbine will be switched off (illustration 19).

The compressor will be immediately stopped after the switching off of the turbine.
As soon as the compressor is switched off, the turbine pipe goes to the vertical position. The remaining
water can then flow from the jet ring and icing over will be avoided.
