The machine and the various operating statons
are transported in special containers, generally
wooden crates. Unpacking must be done near to
thefinalinstallationpositionofthemachine.The
crates can be esily transported by a lift truck.
When the crate has been positioned correctly,
unpack as follows:
a. Unnail the lid and remove it. Do the same
thing with the side panels. Pay particular
attention to the wooden spacer blocks located
between the sides of the crate.
b. Remove the spare parts box and other
components from the crate.
c. Unnail the woodwn blocks that the hold the
machine in place during transport and remove
the cellophane sheet.
d. Check that the contents of the crate
correspond to the description given in the
shipping documents.
e. Check that all the covers and panels have
been correctly fitted and that there are no
loose parts.
f. Visually inspect all the electrical components
to make sure that they are not damaged.
g. If any part/component is missing, stop
unpacking and immediately notify Tetra Pak
Hoyer.
h. If the machine has been damaged during
transit, notify the insurance company
imediately. Do not proceed beyond

The machine is completely validated and
regulated by producing ice-cream for about an
hour before shipment to the customer.
Consequently to install it, only the connections
with the mixture entrance and ice-cream exit,
compressed air pipes and the electric power need
to be carried out. No machine internal regulation
is needed and we strongly advise the regulations
carried out in the factory are not altered.
The installation procedure is carried out by the
following operations:
a. Position the machine in the place of
production, checking the dataplate data to
assure yourself that the machine is
compatible with the existing electric
powering
b. Connect the ice-cream entrance pipes to the
production freezer (Position 1, Figure 4.3)
c. Connect the compressed air pipe
d. Connect the machine to earth and to the
electrical powering.

6.1 Preliminary checks
Before starting the production, it is advisable to
carry out the following checks:
a. a. Ensure that the machine has been
previously made hygienic.
b. Ensure that the main switch has been
activated
c. Ensure that the valves for the pneumatic
powering are open.
d. Ensure that the emergency key is released.
e. Check the correct tightening of the clamp
connections.
f. Verify the correct connection of the freezer
pipes.
6.2 Start of production
a. Wait until the ice-cream has reached the
required density.
b. Set the dosing time on the timer (Dosing
time).
c. Set the dosing time break (1 or 2 seconds)
on the timer (Dosing time).
d. Turn the selector (Dosing). After the few
seconds (dosing break time), the doser carries
out the work cycle according to the set
dosing.
e. Turning the selector (up-down) to “Up”, the
doser starts the automatic work cycle with
the raised position far from the container.
Turing the selector (Up-down) to “Down”,
the doser starts the automatic work cycle in
the following sequence:
- vertical nearing to the container to be filled
using the pneumatic slide;
- doser opening and re-raising phase start
after the set dosing time;
- the doser goes away vertically;
- doser closing which can be advanced or
delayed using a regulatable height limit on
the pneumatic slide;
- doser rest in the “Up” position for the set
time.
f. Insert the tub under the doser and start the
production.
