BLAST CHILLER ISTRUCTION C-200306/2011
•
If at the end of the maximum blast chilling interval the core
probe continues to display a temperature 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
w
ill be activated.
The blast chilling cycle continues until the end chilling tem-
perature has been reached; display
h
counts back the min-
utes remaining until the end of the cycle.
N
ota: press push-button
i
t
o mute the alarm; press push-but-
ton again to clear the alarm display.
• At the end of the chilling cycle, the appliance automatically
switches to the set storage temperature for an indefinite in-
terval (like a standard storage appliance).
Nota: LEDs
f
switch off while LEDs
g
light up.
• The cell temperature is constantly shown on display
j
; dur-
ing this cycle, defrost cycles are performed at regular inter-
vals with duration set as required (parameter programming
reserved for installation technician). The factory setting for
positive storage temperature is +2°C.
• Press push-button
y
to set the appliance to STOP status
(relative LED switches off ), ready for a new cycle.
• To modify the final blast chilling temperature, consult the
user programming instructions.
4.4 SOFT TIMED BLAST CHILLING
• Press push-button
w
(relative LED lights up), then press
push-button
t
to select the timer mode (LED
t
B on). Dis-
play
h
shows the maximum chilling time (set by default to
90 minutes).
To modify this time, press push-buttons
u
and
i
(time in
minutes).
• Press push-button
y
to start the appliance. LED
t
B and
push-button LEDs remain on and LEDs
f
flash throughout
the cycle.
• Internal cell temperature is shown on display
j
.
• 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 in-
definite 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
y
to set the appliance to STOP status
(relative LED switches off ), ready for a new cycle.
Use the storage function sparingly. After chilling, food
products should be placed in storage cabinets.

.5 HARD BLAST CHILLING FEATURES
When the HARD function is used, chilling takes place in two
stages:
• an initial “Hard” stage when the air temperature is brought
down to below 0°C in order to accelerate chilling;
•
a second“Soft”stage, involving air temperatures around 0°C.
4.6 HARD BLAST CHILLING BY TEMPERATURE
• Press push-button
e
(relative LED lights up), then press
p
ush-button
t
t
o 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
f
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).
• Once the cycle has been started, the appliance operates ini-
tially with an air temperature below 0°C (LED on push-button
e
flashes), then with temperatures around 0°C (LED on
push-button
e
on).
Nota: 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 (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
h
shows blast chilling time reset to zero.
• The alarm (ALL 14) and conservation functions cut in with
relative indicators in the same way as for timed Soft blast
chilling.
• Press push-button
y
to set the appliance to STOP status
(relative LED switches off ), ready for a new cycle.
