4.2.2 Ice cream intake and outlet connection
Connect the mix supply pipe to the mix pump
inlet connection (6) on the front of the machine.
The machine has a CIP washing programme
permitting thorough, safe washing of the machine
without dismantling its parts; it will therefore be
necessary to prepare the required connections
between the CIP washing pump and solutions and
the mix pipe.
Make sure that the mix flows “spontaneously”
to the machine connection (6), and does not need
to be suctioned by the freezer pump; this may be
done by simply positioning the aging vats higher
than the freezer (check that the spontaneously
flowing supply is sufficient even when the mix
level in the containers is low), or by installing a
suitable centrifugal pump close to the vats. Take
care to ensure that there is no air getting into the
pipes, which could pollute the product and result
in fluctuation of ice cream overrun.
CAUTION:
Pipes must be dismantled and washed
thoroughly after completing this procedure
to ensure that no hard solid particles are
conveyed toward the freezer mix pump. This
is very important as solid particles such as
metal burr or welding residues could severely
damage the freezer pump and will invalidate
the guarantee.
Connect up the ice cream outlet (7) to the utility.
Use the shortest possible pipe, with as few
curves as possible, and use a pipe which is shiny
inside; the pipe does not need to be insulated.
Make sure that ice cream pressure in the
cylinders does not exceed 12 bar (the absolute
maximum permitted value); if this should occur,
move the freezer closer to the ice cream utility
and/or use hot gas to produce softer ice cream.
Connect the compressed air supply pipe to the
connection on the rear of the machine; it is
recommended that an easily removable tap and
connection be assembled close to the machine
connection.
The supply pressure measured on the machine
4.2.3 Compressed air connection
must never drop below 6 bar. It is strongly
recommended that the compressed air supply
in the place of installation be fitted with an air
drying system and A0 filters to remove oil
vapours and residual fine particles.
CAUTION:
Electrical connection must be made
exclusively by competent technicians who are
familiar with safety legislation and authorised
to perform and certify electrical installations.
Check the identification plate to make sure that
the machine is compatible with the site’s power
supply. Connect the machine’s power supply to
the site’s distribution panel and protect it with a
4.2.4 Electrical connection
suitable device, complying with all regulations
for correct electrical installation in effect in the
place of installation.
We recommend installing an automatic circuit
breaker on the distribution panel, complying
with local regulations.
