- Remove one tray at a time, lifting it and pulling it past
the retaining slide. The upper trays will tilt downwards
to facilitate loading.
- Load all products starting at the front, without inserting
products with a temperature above 30°C, ensuring that
all spaces are filled. The bottom of the product must
rest at the bottom of the compartment with the label
facing the window so that it can be identified.
Allproductsshouldloadeasily,donotinsertproducts
which are too large for the space.
- Push in the trays completely, ensuring that they go
past the retaining slide.
The sealed end of bags may be caught under the spiral,
preventing the free fall of the product.
Fold the seal towards the front of the unit and upwards
before inserting the product in the spiral.
More fragile products must be placed on the lower
trays to prevent damage when they drop.
START-UP
Each time the machine is started the number of trays
connected to the system are checked by the electronic
controls and indicated on the display.
This permits to check that all trays were correctly con-
nected after loading.
Also the number of actually connected compartments is
checked.
The cooling unit is sized to ensure that a temperature
of 7°C is reached in the lower section of the cabinet
within 45 minutes from from the end refilling, if the
machinewasalreadyrunning.Ifthemachinehadbeen
switched off for a long period it will be necessary to
wait that the operating temperature is reached before
inserting refrigerated products.

in each spiral, even if the machine configuration has an
empty position.
A motor can be in one of the following conditions:
- motor functioning;
- motor not present; when the motor is not detected at
machine start-up.
- motor disconnected; when a motor detected at ma-
chine start-up is not detected during a selection.
- motor blocked; when the positioning button is not
operated within the “timeout”.
- empty spiral; when, with the dispensing control in-
stalled, no dispensed product is detected.
Note:
By restarting the machine any blocked motors are de-
tected as not present.
