Technical Information
5 - MACHINE ON/OFF
When the equipment is powered, it will appear in
STANDBY conditions (scrolling text on the display). To start
the machine press the button (1) for at least 3". Similar to
machine without cycles in progress, to switch it off simply
press the button (1) for at least 3".
Where a cycle was in progress, and the situation is returning
from a blackout the appliance, once reconnected, will
resume from the interrupted cycle.
5.1 - Compressor preheating management
Upon ignition of the equipment a compressor preheating
time of 120 minutes must be respected where the blast
chiller is not available.
The scrolling text will appear "Compressor Heating-
Riscaldamento Compressore" and then the fixed lettering
"XXX min" to represent the time remaining. These two
messages will alternate until the end of heating. This phase
can be bypassed by pressing the "HACCP" (11) button for
approximately 5 seconds.
6 - DATE AND TIME SETTING
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 laels shown below will appear on the left
display; the right display will show the 2-digit numeric
value to be set:
Hour(Ora) / Minute(Minuti) / Day(Giorno) / Month(Mese) /
Year(Anno)
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.
7 - BLAST CHILLING CYCLES
7.1 - General operating principles
Pre-cooling of the machine should always be performed
upon initial running of a blast chilling or deep freezing
operation. This optimises 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)
12
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 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 "SONDA NON INSERITA -
PROBE NOT INSERT" 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 strorage status symbols
During chilling the LED that lights the sybol 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 - Fine Ciclo". 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 compresser 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.
