PROGRAMMING AND OPERATING INSTRUCTIONS
Starting up the Appliance
Preheating function of compressor
When power is initially supplied to the cabinet, a 2 hour
pre-heating phase starts and the display shows some
blinking dashes. During this phase the machine cannot be
started. This important information is shown on a yellow
label placed inside the door.
Initial pre-heating is necessary in order to safeguard the
compressors life. Only if strictly necessary (and under
the customer's responsibility) is it possible to by-pass
countdown by pressing the button "Printer/HACCP" for
roughly 5 seconds.
This function is not activated if machine stops/starts
operating due to lack of power during working cycle.
When the appliance is powered up, it can be:
- ON: displays icon 14, 15 and left LED 5A
- OFF - STAND-BY LED: on push-button 1
To switch from one status to another, press push-button 1.
Whenever the appliance switches from STAND-BY status
to ON, a self-test as 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 (38°F / 3°C)
Pre-cooked food is rapidly chilled (90) to a temperature
of 38°F / 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 soft cycle
is recommended for delicate, thin foods such as rice,
vegetables and fried foods.
- HARD BLAST CHILLING (38°F / 3°C)
This process is designed to cool food products with a
thickness greater than 2.3cm / 1" and is very effective
for dense, greasy or large-sized foods. Variable air
temperatures are used to accelerate penetration of cold
into the product.
- BLAST FREEZING (0°F / -18°C)
This function freezes the product completely to a
temperature of 0°F / -18°C in approximately 4 hours. The
rapidity of the process prevents formation of macrocrystals
essential to ensure that the product retains its original

consistancy and quality when thawed for consumption.
- AUTOMATIC CONSERVATION
At the end of cycle (chilling and freezing), the appliance will
automatically switch to the required storage temperature.
Two different end-cycle modes are available for 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)
5.2 SOFT BLAST CHILLING BY TEMPERATURE (pre-
cooked, hot foods)
- To select this cycle, press push-button 2, then press push-
button 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 relatedto the push-buttons pressed illuminate
throughout the cycle, while LEDs 12 flash.
- Display 14 indecates 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 15.
- The instrument timer starts the countdown of the
maximum blast chiling time as soon as the temperature
measured by the core probe falls below the temperature
of 149°F / 65°C (the dot at the bottom right of display 14
flashes.)
- During the blast chilling cycle, the air temperature is
around 32°F / 0°C and may gets as low as 23°F / 5°C. This
function is designed to gaurantee uniform cooling of
the product, preventing frost formation on the surfaces.
During the blast chiling cycle, the compressor may
therefore stop and restart, depending on the reading of
the compartment temperature probe.
- The blast chilling phase ends only when the core probe
(inserted in the product core) indicates that the set blast
chilling temperature (38°F / 3°C)) has been reached as
signalled by an intermittent beep for a minute. During the
