Troubleshooting
beep, LEDs 13 and 14 will flash. Display 15 indicates the
temperature inside the compartment, while display 14
shows blast chilling time reset to zero.
- 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 will be activated.
The blast chilling cycle continues until the end chilling
temperature has been reached; display 14 counts back the
minutes remaining until the end of the cycle.
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 temperature for
an indefinite interval (like a standard storage appliance).
LEDs 13 switch off while LEDs 14 light up.
- The compartment temperature is constantly shown on
display 15; 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 36°F /
2°C.
- Press push-button 6 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.
IMPORTANT: During chilling or shock freezing by core
sensor it's possible to read:
- The room temperature by pressing push-button
- The evaporator temperature by pressing push-button

5.3 SOFT TIMED BLAST CHILLING

- Press push-button 2 (relative LED lights up), then press
push-button 5 to select the timer mode (LED 5B on).
Display 14 shows the maximum chilling time (set by
default to 90 minutes).
To modify the time, press push-button 7 and 8 (time in
minutes).
- Press push-button 6 to start the appliance. LED 5B and
push-button LEDs remain on the LEDs 13 flash throughout
the cycle.
Internal cell temperature is shown on display 15.
- When the maximum chilling time has counted back
34
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.
IMPORTANT: Use the storage function sparingly. After
chilling, food products should be placed in storage
cabinets.
HARD BLAST CHILLING
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 32°F / 0°C in order to accelerate
chilling;
- a second "Soft" stage, involving air temperatures around
32°F.
IMPORTANT: During chilling or shock freezing by time
it's possible to read the evaporator temperature by
pressing push button.

5.4 HARD BLAST CHILLING BY TEMPERATURE

- Press push-button 3 (relative LED lights up), 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 relative to the push-buttons pressed illuminate
throughout the cycle, while LEDs 13 flash.
- Display 14 indicates the maximum blast chilling
time (starting temperature to end of the blast chilling
temperature - factury 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 chilling time as soon as temperature
measured by the core probe falls bellow the temperature
of 149°F / 65°C (the dot at the bottom right of display 14
flashes).
- Once the cycle has been started, the appliance operates
initially with an air temperature below 32°F / 0°C (LED on
push-button 3 flashes), then with temperatures around
32°F / 0°C (LED on push0button 3 on). The first stage of
the cycle is completed when the core probe detects a
