ALARMS
In case of probe failure, the display will show the following
alarm messages:
“A1”: Tank 1 probe disconnected
“A2”: Tank 1 probe short circuit
“A3”: Tank 2 probe disconnected
“A4”: Tank 2 probe short circuit
“A5”: Tank 3 probe disconnected
“A6”: Tank 3 probe short circuit
During operation, the temperature display shows the
temperature of the product in the bowls, cyclically showing
the temperature of the product in each bowl. To see which
tank is being referred to with the temperature reading, it is
necessary to check which decimal point is being shown.
If the decimal point viewed is on the left, the temperature
reading refers to Bowl 1 (see Fig.2 Page 4).
If the decimal point viewed is in the centre, the temperature
reading refers to Bowl 2 (see Fig.2, Page 4).
If the decimal point viewed is on the right, the temperature
reading refers to Bowl 3 (see Fig.2, Page 4).
Note: If the temperature display on the unit
switches off, start it again by pressing the
. key. If the display fails to switch back on,
turn off the machine and seek assistance
from a specialized technician.
Important: While using the machine, the
temperature display must always be on so
as to show the temperature of the product in
the tanks.
6.5. Adjusting slushy consistency
The consistency of the slushy may be adjusted (+/-)
by means of the screw shown in the figure +: thicker
consistency, -: thinner consistency.
The adjustment may be made by hand or
with the aid of a suitable flat-tip screwdriver.
The machine comes straight from the factory with the valve
(2) set in an intermediate position between the maximum (E)
and minimum (D) consistency points.
If you wish to raise the consistency of the product all that is
needed is to turn the valve counterclockwise (left). We can
see that the tab lowers in position towards point E (point of
maximum consistency).
If you wish to lower the consistency of the product all that
is needed is to turn the valve clockwise (right). We can see
that the tab moves higher in position towards point D (point
of minimum consistency).
