- Press the
UP
or
DOWN
key to select the
duration
of the blast
chilling cycle (the starting value displayed is the one set by de-
fault, parameter P19 or P20 respectively for positive blast chill-
ing
cycle or negative blast chilling cycle).
+
The cycle time modification is not permanent (it does
not change the default v alues for parameters P19 and
P20). When the cycle is next set, the default values set
under parameters P19 and P20 will be shown again.
- Wai t 5 seconds or press the
SET
key to confirm (the cycle time
display becomes fixed).
- Press the
SET
key to start the program. During the blast chill-
ing cycle the display shows the total cycle time (parameter P19
or P20 respectively for positive blast chilling cycle or negative
blast chilling cycle).
+
The time is displayed in the form of a decimal number,
where the integer part represents the hours and the dec-
imal part represents the minutes (for example, “1.30” indi-
cates the time 90 minutes, i.e. 1 hour and 30 minutes).
At the end of the blast chilling cycle, the
storage
phase starts
(signalled by a beep). The temperature measured by the cell
probe is shown on the display.
Storage phase characteristics:
- a fter a positive blast chilling cycle (parameter P19) room tem-
perature setting equal to the value set for parameter P17;
- after a negative blast chilling cycle (parameter P20) room
temperature setting equal to the value set for parameter P18. 8.

Selecting and starting special functions
The appliance is provided with special functions to manage the
following blast chilling functions:
-
manual defrost,
-
cell sterilization
(optional, if provided by the blast chiller),
-
needle probe heating
(optional, if provided by the blast chiller)
.
The storage phase starts automatically at the end of the special
function and the buzzer will sound intermittently for the set time
(this can be modified by the user under parameter P 0).
To silence the buzzer in advance, press the DOWN key.
Manual defrost
Defrosting is normally performed by the User with the blast chill-
er door open (cell heating). Door opening or closure has no ef-
fect on the defrost process.
To start defrosting press and hold the
DOWN
key for 4 seconds.
+
The defrost configuration and duration are determined
by the parameters P 5, P 7, P11, which can be modified
by the User. During the defrost, the display shows the
“dEF” string.
Cell sterilization
Sterilization can be enabled if the value of parameter P23 is equal
to 1. To activate a sterilization cycle there must be no program or
other special function in progress and the blast chiller door must
be closed.
To start the sterilization cycle hold down the
UP
key for 4 sec-
onds.
+
The sterilization cycle start and duration are determined
by the parameters P 8, P24, P25, which can be modified
by the User. During the sterilization cycle the display
shows the “StE” string.
In the case of a cell probe error “Er2”:
- before the sterilization cycle start, the sterilization cycle does
not start;
- during the sterilization cycle, the sterilization cycle continues
normally.
If at start-up or during the sterilization cycle the cell temperature
is lower than the reference value (parameter P25), the display will
show the “cLd” string.a.
Needle probe heating
Needle probe heating can be activated if the value of parameter
P23 is equal to 2. Door opening or closure has no effect on needle
probe heating. To activate needle probe heating there must be no
program or other special function in progress.
To start needle probe heating hold down the
UP
key for 4 seconds.
+
The needle probe heating configuration is determined
by the parameters P28 and P29, which can be modified
by the User. During needle probe heating, the display
shows the “Prb” string.
Stopping and restarting a program or a
special function
During the execution of a program or a special function, press
the
SET
key to stop it.
If a program has been completed, press the
SET
key again to
restart from the point in which it was interrupted.
+
If the restarted program is of the manual type, the cycle
starts from the beginning for the set cycle time.
If a special function was not completed, it is not possible to re-
start from the point where it was interrupted.
