3.2 Operating tips
Before starting up the appliance, clean the inside of the cell 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.
possible to the evaporator.
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 protrude or touch the tray. The probe must be cleaned and sani­tised before each new cycle (operation) to prevent inadvertent contamination.
b) Ensure that there is sufficient clearance
between trays to enable free air circula­tion. If the appliance is not completely full, distribute the trays and foods evenly throughout the available space.
e) Avoid covering the trays and/or contain-
ers 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.

Delayed start of compressor during first starting
(for models E15-40 / E15-65 / E15.2-70)
Pre-heating function of compressor sump
When the board is reached by mins tension, a 2-hour pre-heating phase starts and the display shows some blinking dashes “---”. During this phase the machine cannot be started.
NOTE
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 compressor’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
This function is not activated if machine stops/starts operating due to lack of power during working cicle.
5.1 STARTING UP THE APPLIANCE
When the appliance is powered up, it can be:
ON displays 15 and 16 and left LED 5A on push-button 5 on,
LED 1 off
OFF-STAND-BY LED on push-button 1 on
To switch from one status to another, press push-button 1 . 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.
• HARD BLAST CHILLING (+3°C)
This process is designed to cool food products with a thickness greater than 2-3 cm. Variable air temperatures are used to accelerate penetration of cold into the product.
42
GB
BLAST FREEZING (-18°C)
This function freezes the product completely to a temperature of -18°C in less than 4 hours. The rapidity of the process 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
IMPORTANT: work cycles and modes can only be selected when the appliance is ON (LED
on push -button 6 off)
5.2 SOFT BLAST CHILLING BY TEMPERATURE (pre-cooked, hot foods)
• To select this cycle, press push-button 2 (relative LED lights up), then press push-but-
ton 5 to select the temperature mode (LED 5A on)
• Insert the core probe into the core of the product to be chilled.
• Start up the cycle by pressing push-button 6 . LED 5A and those relative to the push-
buttons pressed illuminate throughout the cycle, while LEDs 13 flash.
• Display 15 indicates the maximum blast chilling time (starting temperature to end of
the blast chilling temperature - factory setting - 90 minutes).
• The temperature measured by the core probe is shown by display 16 .
• 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 display 15 flashes).
• 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 the surfaces. 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) indi-
cates that the set blast chilling temperature (+3°C) has been reached as signalled by an
intermittent beep for a minute. During the beep, LEDs 13 and 14 flash.
Display 16 indicates the temperature inside the cell, while display 15 shows blast chilling time reset to zero.
43
GB
• If at the end of the maximum blast chilling interval the core probe continues to display a tem-
perature higher than the value for the end of blast chilling, the displays will indicate an alarm for excessively long chilling (ALL 14) alternating with the temperature and time; at the same time, the alarm beep will be activated. The blast chilling cycle continues until the end chilling temperature has been reached; dis-
play 15 counts back the minutes remaining until the end of the cycle.
NB: Press push-button 8 to mute the alarm; press push-button again to clear the alarm display
• At the end of the chilling cycle, the appliance automatically switches to the set storage tem-
perature for an indefinite interval (like a standard storage appliance).
NB: LEDs 13 switch off while LEDs 14 light up.
• The cell temperature is constantly shown on display 16 ; during this cycle, defrost
cycles are performed at regular intervals with duration set as required (parameter pro­gramming reserved for installation technician). The factory setting for positive storage tem­perature is +2°C.

• Press push-button 6 to start the appliance. LED 5B and push-button LEDs remain
on and LEDs 13 flash throughout the cycle.
• Internal cell temperature is shown on display 16 .
• When the maximum chilling time has counted back to 0, the chilling cycle is completed and
the appliance automatically switches to the set positive storage temperature for an indefi­nite interval.
• LEDs illuminate and the beep is activated when the cycle is finished (as in the chilling cycle
by temperature). The same applies for the positive storage function.
Press push-button 6 to set the appliance to STOP status (relative LED switches off), ready for a new cycle.
44
GB
MPORTANT: Use the storage function sparingly. After chilling, food products should be

buttons pressed illuminate throughout the cycle, while LEDs 13 flash.
• Display 15 indicates the maximum blast chilling time (starting temperature to end of
the blast chilling temperature - factory setting - 90 minutes).
• The temperature measured by the core probe is shown by display 16 .
• 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 display 15 flashes).
• Once the cycle has been started, the appliance operates initially with an air temperature
below 0°C (LED on push-button 3 flashes), then with temperatures around 0°C (LED on
push-button 3 on). NB: The first stage of the cycle is completed when the core probe detects a temperature of +20°C in the product core.
• The blast chilling phase ends only when the core probe (inserted in the product core) indi-
cates that the set blast chilling temperature (+3°C) has been reached as signalled by an
intermittent beep for a minute. During the beep, LEDs 13 and 14 flash.
Display 16 indicates the temperature inside the cell, while display 15 shows blast chilling time reset to zero.
