4.1 MAX SHELF LOAD
ATTENZIONE
MAX shelf grid load is 25 kg. (uniformed distribuited load)
4.2 STORING PRODUCTS
ATTENTION
Before exposing the goods, wait that the temperature set on the electronic control be achieved.
The unit is designed to preserve frozen food products and when they are been stored, the products
must have a temperature that is close to the temperature required for preserving food.
• Do not place hot products in the unit; all products introduced into the unit must be already frozen.
• Before loading goods in the refrigerated table, make sure that the temperature reaches the de-
sired temperature set on the control panel. In order for the unit to work properly, products must
be arranged in such a way as not to obstruct the circulation of refrigerated air inside the unit
itself. If frozen products remain in non-refrigerated areas for a period longer than two hours, they
must be taken into the fridge cells to refrigerate them before storing them into back into the unit.
In order for the unit to work properly, be advised of the following:
• when the doors are opened, cold air is released and therefore, it is advisable to limit opening
the doors and only do so for the time required to load products
• Storing non-frozen products will worsen the operating conditions of the unit, risking damaging
products that are already stored inside the unit. Therefore, avoid placing products in non-
refrigerated areas to prevent excessive loss of cold.
• make sure all of the ventilation inlets and outlets of the refrigerated table are free of obstacles.
• The door of the cold-room, must only be opened for the time required to load or unload
products and it will keep the internal temperature of the unit from rising and therefore from
consuming more energy, which would be required to bring the product back to its initial pre-
servation temperature.
• The units are designed for displaying refrigerated products that must reach warehouses at an
ideal temperature for food preservation.
Products that are dispatched from suppliers must be stored in the MINI Cold-Rooms or in the fridge
cells in order to avoid excessive loss of cold due to long periods of time without refrigeration.
In order for the unit to work properly, products must be ar-ranged in such a way as not to block or
obstruct the circulation of refrigerated air.
Make sure that the food cold chain is respected, from the moment of transport and/or the
storage in the refrigerated unit.
ATTENTION
Children must be monitored closely to make sure they do not play with the appliance.

EN
After the password ‘PA2’ has been putted in, press the and keys to scroll through to the required function (e.g. UL). Press the key to
execute the upload. If the operation is successful, the display will show ‘y’, if not it will show ‘n’.
Upload (UL) This function uploads the programming parameters from the device.
UPLOAD: device Copy Card
Format (Fr) This command is used to format the copy card, an operation which is necessary when using the card for the first time. Important:
when the copy card has been programmed, the parameter ‘Fr’ will delete all data that have been entered. This operation cannot be cancelled.
Download from reset:
Connect the copy card when the device is switched off. When
the device is switched on, the download from the copy card will
begin automatically. At the end of the lamp test, the display will
show ‘dLy’ if the operation was successful and ‘dLn’ if not.

ELECTRICAL WIRING
Attention! Never work on electrical connections when the machine is switched on.
The device is equipped with screw or removable terminals for connecting electric cables with a diameter of 2.5mm2(one wire per terminal for power
connections). For the capacity of the terminals, see the label on the instrument. Do not exceed the maximum current allowed; in case of higher loads,
use an appropriate contactor. Make sure the power supply voltage complies with the one required by the instrument. Probes have no connection
polarity and can be extended using a regular bipolar cable (note that the extension of the probes affects the EMC electromagnetic compatibility of
the instrument: pay extreme attention to wiring). Probe cables, power supply cables and the TTL serial cables should be distant from power cables.
