4. PROGRAMMING AND OPERATING INSTRUCTIONS
4.1 DELAYED START OF COMPRESSOR DURING FIRST
S
TARTING (only for MOD.
r
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.
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 cus-
tomer’s responsability) it is possible to by-pass countdown
by pressing the pushbutton“printer/HACCP”for about 5 sec-
onds.
This function is not activated if machine stops/starts op-
erating due to lack of power during working cicle.
4.2 STARTING UP THE APPLIANCE
When the appliance is powered up, it can be:
• ON displays
1%
and
j
and left LED
t
A on push-button
t
on, LED
q
off.
• OFF-STAND-BY LED on push-button
q
on.
To switch from one status to another, press push-button
q
.
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 prevent-
ing dehydration of the cooked food due to evaporation.
Food can thus be stored perfectly for 5 to 7 days without al-
tering its original qualities.
• Hard blast chilling (+3°c)
This process is designed to cool food products with a thick-
n
ess greater than 2-3 cm. Variable air temperatures are used
to accelerate penetration of cold into the product.
• Blast freezing (-18°c)
This function freezes the product completely to a tempera-
t
ure 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 tempera-
ture.
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 ap-
pliance is ON (LED on push -button
y
off).
4.3 SOFT BLAST CHILLING BY TEMPERATURE
(pre-cooked, hot foods).
• To select this cycle, press push-button
w
(relative LED lights
up), then press push-button
t
to select the temperature
mode (LED
t
A on).
• Insert the core probe into the core of the product to be
chilled.
• Start up the cycle by pressing push-button
y
. LED
t
A and
those relative to the push-buttons pressed illuminate
throughout the cycle, while LEDs
1#
flash.
• Display
h
indicates the maximum blast chilling time (start-
ing temperature to end of the blast chilling temperature -
factory setting - 90 minutes).
• The temperature measured by the core probe is shown by
display
j
.
• 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
h
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. Dur-
ing the blast chilling cycle, the compressor may therefore
stop and restart, depending on the reading of the cell tem-
perature probe.
• The blast chilling phase ends only when the core probe (in-
serted in the product core) indicates that the set blast chill-
ing temperature (+3°C) has been reached as signalled by an
intermittent beep for a minute. During the beep, LEDs
f
and
g
flash.
Display
j
indicates the temperature inside the cell, while
display
1%
shows blast chilling time reset to zero.
