Upon initial ignition, it is advisable to check the date and
time set; their accuracy is beneficial in relation to HACCP
management.
To access the clock setting, press for more than 5 seconds
the Temperature/Time button (5) with the machine in
Stop mode. The labels shown below will appear on the
left display; the right display will show the 2-digit numeric
value to be set:
Hour / Minute / Day / Month / Year
The Temperature/Time button (5) can be used to scroll
through the labels, while with the +/- buttons (21/7) it is
possible to change the values.
After the year value the change will be automatically
saved.
Blast chilling cycles
General operating principles
Pre-cooling of the machine should always be performed
upon initial running of a blast chilling or deep freezing
operation. This optimizes the subsequent work cycle,
reducing the time.
Blast chillers are refrigeration systems that work with a two-
phase cycle:
• Chilling phase (limited duration)
• Storage phase (unlimited period)
The chilling phase starts upon pressing of the “Start/Stop”
button (22) and continues until the end of the chilling
phase that is used to achieve the time set (Time chilling) or
for reaching of the product temperature set (Temperature
chilling); changing to the unlimited duration storage cycle
takes place automatically (except for the HARD+HARD
negative chilling cycle). It is possible to stop the chilling or
storage at any time by pressing the“Start/Stop” button (22).
Chilling time
During this type of chilling, the display (18) shows the cell
probe temperature while the other display (19) shows the
time remaining at the end of the chilling phase. The Time
chilling LED (6) is lit as is the time symbol (20).
Temperature chilling
If Temperature chilling is selected, at the start of a cycle a
check is performed of the correct insertion of the product
probe (if enabled). If the test provides a negative result
an alert appears on the display “PROBE NOT INSERTED”
and the beeper sounds for 60 seconds (parameter c9);
that symbol disappears when the beeper is silenced by
pressing the button (7). If instead the button is pressed
again (5) switching to Temperature cycle, the cycle
continues based on the data read by the product probe.
If nothing is pressed, the temperature cycle automatically
switches into a Time cycle for the remaining duration of
the countdown.
During this type of chilling, a display (18) will show the
temperature of the probe (the highest value of the two)
and the other (19) will show a countdown. The countdown
only starts when the insert temperature is less than 149°F
(65°C). The temperature chilling LED (4) is on as is the
probe insert symbol (17).
Chilling and storage status symbols
During chilling the LED that lights the symbol will be
lit and flashing. Upon completion of chilling, this LED
flashes alternately with the LED located beneath the
storage symbol (8) while the beeper sounds for 60 sec,
and the scrolling text appears “End Cycle”. After this time,
the chilling LED (9) switches off, the storage one starts
flashing (8) and the scrolling text disappears (even when
the beeper silencer button (7) is pressed.
The LED (8) will flash when the compressor is on while if
the set value has been reached, they will only remain lit
until transition to storage. Similarly with storage, the LED
(9) will flash when the compressor is active and will remain
lit for the rest of the storage.
Chilling phases
Pressing the positive chilling button (2) or negative chilling
button (3) allows selection of a different chilling mode.
The number of LEDs lit (23) or (24) define the “intensity”
of chilling. The “Time” or “Temperature” chilling mode
