5.2 Ice cream pressure setting
Ice cream pressure is adjusted using the pneumatic
pressure regulator (4); the adjusted air pressure is
displayed on the pressure gauge (5).
Pressure is indicated by the pressure gauge placed
on the front of the machine, specifically on the
pipe between the pump and the cylinder. For
good ive cream quality, the pressure should
normally be between 4 and 8 bar.
The safety valve opens automatically if the
pressure in the cylinder, which appears on the
pressure gauge (6)
, exceeds 12 bar; this prevents
pressure from damaging the freezer.
WARNING:
The adjustment described above takes effect after
an interval of time which varies according to the
operating parameters set.
Wait for the gauge (6) reading to stabilise before
proceeding with further adjustments.
Overrun control
The illuminated switch (9), is turned clockwise,
to turn on the compressed air intake to the supply
pump and will light up to indicate activation.
Pneumatic regulator
(2), is used to set the
pressure - read on pressure gauge (3) and
therefore the quantity of compressed air
introduced into the supply pump to obtain the
required overrun. The greater the pressure of the
compressed air introduced, the greater the
overrun obtained; up to the capacity of the mix,
over this limit the compressed air cannot be
absorbed by the ice cream, and is expelled
separately. Switch (9) is active only if the pump
and refrigerator compressor are operating.
