3. ADVICE TO ENSURE EFFICIENT APPLIANCE OPERATION

0.5 - 2cm.

3.1 SHUTDOWN PROCEDURES

In the event of emergency, shut down the appliance by swit-

hing o power at the main panel, by means of the knife

c switch or by removing the plug from the power socket.

3.2 OPERATING TIPS

efore starting up the appliance, clean the inside of the cell

B thoroughly.

3.2.1 Pre-cooling

Before using the appliance for the ﬁrst time, or after a prolonged period of disuse, pre-cool the cell by running an empty cycle until the set operating temperature has been reached. To ensure optimal performance without any alteration to food quality:

• arrange food products in such a way as to favour the circulation of cold air throughout the cell;

• open the door as little as possible.

3.2.2 Loading the appliance a) Ensure that foods to be chilled and/or frozen are separate

and do not have a thickness greater than 50-80 mm. Do not load the appliance beyond the quantity recommended by the manufacturer.

d) Position the core probe at the centre of the largest product

or food item; make sure that the tip of the probe does not

rotrude or touch the tray.

p The probe must be cleaned and sanitised before each new cycle (operation) to prevent inadvertent contamination.

e) Avoid covering the trays and/or containers with insulating

covers or ﬁlm. The more the product is insulated, the more time is required for chilling or freezing. Trays must be packaged when the product has been chilled, before being placed in storage.

English

b) Ensure thatthere issucient clearance between trays to ena-

ble free air circulation. If the appliance is not completely full, distribute the trays and foods evenly throughout the available space.

c) Position trays inside the tray compartment as far as they will

go, as close as possible to the evaporator.

4. PROGRAMMING AND OPERATING INSTRUCTIONS

IN THE EVENT OF MALFUNCTION, SEEK THE ASSISTANCE OF A CERTIFIED TECHNICIAN

4.1 DELAYED START OF COMPRESSOR DURING FIRST

English

TARTING (only for MOD.

Pre-heating function of compressor sump.

When the board is reached by mins tension, a 2-hour preheating phase starts and the display shows some blinking dashes“---”. During this phase the machine cannot be started.

Nota: The delayed start takes place only if the machine is given power by its dedicated magnetothermic switch.

• It is therefore advisable that, after first starting, the machineis

started or stopped by using the control panel pushbutton. This way, the compressor pre-heating function is guaranteed, and the machine starting takes place in a direct way.

• Initial pre-heating is necessary in order to safeguard the com-

pressor’s life. Only if strictly necessary (and under the customer’s responsability) it is possible to by-pass countdown by pressing the pushbutton“printer/HACCP”for about 5 seconds.



• Hard blast chilling (+3°c)

This process is designed to cool food products with a thick-

ess greater than 2-3 cm. Variable air temperatures are used

n to accelerate penetration of cold into the product.

• Blast freezing (-18°c)

This function freezes the product completely to a tempera-

ure of -18°C in less than 4 hours. The rapidity of the process

t prevents formation of macrocrystals essential to ensure that the product retains its original consistency and quality when thawed for consumption.

• Automatic conservation

At the end of each cycle (chilling or freezing), the appliance will automatically switch to the required storage temperature.

Two different end-cycle modes are available for each cycle:

• By temperature - the cycle ends when the probe reaches

the required temperature.

• Timed - cycle length is pre-set.

work cycles and modes can only be selected when the appliance is ON (LED on push -button

off).

This function is not activated if machine stops/starts operating due to lack of power during working cicle.

4.2 STARTING UP THE APPLIANCE

When the appliance is powered up, it can be:

• ON displays1%andjand left LEDtA on push-button

on, LEDqoff.

• OFF-STAND-BY LED on push-buttonqon.

To switch from one status to another, press push-buttonq. Whenever the appliance switches from STAND-BY status to ON, a self-test is carried out: all LEDs and displays are switched on, push-buttons are checked, then the installed software version is displayed.

Operation

The main work cycles (chilling/freezing) performed by the appliance:

• Soft blast chilling (+3°c)

Pre-cooked food is rapidly chilled (90’) to a temperature of +3°C, thus preventing proliferation of bacteria and preventing dehydration of the cooked food due to evaporation. Food can thus be stored perfectly for 5 to 7 days without altering its original qualities.

• The temperature measured by the core probe is shown by displayj.

• The instrument timer starts the countdown of the maximum blast chilling time as soon as the temperature measured by the core probe falls below the temperature of +65°C (the dot at the bottom right of displayhflashes).

• During the blast chilling cycle, the air temperature is around 0° C. This function is designed to guarantee uniform cooling of the product, preventing frost formation on thesurfaces. During the blast chilling cycle, the compressor may therefore stop and restart, depending on the reading of the cell temperature probe.

• The blast chilling phase ends only when the core probe (inserted in the product core) indicates that the set blast chilling temperature (+3°C) has been reached as signalled by an intermittent beep for a minute. During the beep, LEDs andgflash. Displayjindicates the temperature inside the cell, while display1%shows blast chilling time reset to zero.
