Technical Information

7.2 - 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 will be set by pressing the button (5). Lighting up of 

the corresponding LEDs on the sides will define the type 

of chilling. 
Each time the positive chilling button (2) is pressed the 

display will show successively for 3 seconds one of the 

following cycles: 
LIGHT, SOFT, MEDIUM, FAST.
Each time the negative chilling button (3) is pressed the 

display will show successively for 3 seconds one of the 

following cycles:
LIGHT, SOFT, HARD, RUN.

7.3 - Selecting and starting the positive chilling cycle

When the button (2) is pressed for the first time, “SOFT” 

mode will be selected, represented with lighting up of 

two of the four LEDs (24); subsequent pressing takes to 3 

and 4 LEDs lit and results in the “HARD” mode. Successive 

pressing reduces from 4 to 1 the LEDs lit and so on.

“LIGHT” - 1 LED only on

In this condition, there will be a cell temperature set of 

27F (-3C). This avoids the risk of ice formation during the 

positive chilling phase and it will be used for loads which 

can be damaged by excessively heavy treatment. 

“SOFT” - 2 LEDs on (default)

In this condition, there will be a cell temperature set of 23F 

(-5C). This set will allow quicker chilling for products that 

in any case are fairly resistant to the freezing process.

“MEDIUM” - 3 LEDs on

In this condition, there will be an initial cell temperature 

set of -4F (-20C); after the HARD time, this will be taked to 

a cell temperature of 24F (-3C). This method accelerates 

cooling in the presence of products that are resistant and 

very hot initially.

“FAST” - 4 LEDs on

In this condition, there will be an initial cell temperature 

set of -4F (-20C), after the HARD time, this will be taken to 

a cell temperature of 23F (-5C). This method accelerates 

cooling in the presence of products that are resistant and 

very hot initially.
Once the MEDIUM or FAST cycles are started, to modify the 

HARD phase duration simply press the button (2) that will 

show on the display (19) the words “Hard” and will result 

in flashing on the display (18) the value in minutes of the 

HARD phase. With the +/- buttons it is possible to increase 

or decrease the value and confirm with the button (2) or 

wait 5 seconds (N.B. THE CHANGED VALUE ONLY APPLIES 

TO THE CYCLE IN PROGRESS).
Once the cycle is selected, it is necessary to select the Time 

or Temperature mode by pressing the button (5) until 

coming on of the relevant LED.
At this point to start the cycle press the START/STOP 

button (22).
In the even of Temperature chilling, it is possible to 

change this chilling end value by pressing the button (2) 

or (3) depending on the type of chilling in process. Having 

pressed the button, the display (18) will appear the value 

of the end chilling temperature set, which can be modified 

within the envisaged range. Having pressed the button (2) 

or (3) or after 5 seconds the changed value is saved.

7.4 - Selection and starting the Negative chilling cycle

Pressing the button (3) for the first time will select the 

“HARD” mode, represented by coming on of three of the 

four LEDs (23) present. Subsequent pressing will take to 

4 the LEDs lit and will return into “RUN+HARD” mode. 

Successive presses reduce from 4 to 1 the LEDs and so on. 

“LIGHT” - 1 LED only on

In this condition, there will be a cell temperature set of 

23F (-5C); after the SOFT time defined by the parameter 

(ts) this will move to a temperature of -22F (-30C). This 

mode is for use on large pieces where it is important to 

homogenise the chilling cycle.

“SOFT” - 2 LEDs on

In this condition, there will be a cell temperature set of 

-4F (-20C); after the SOFT time defined by the parameter 

(ts) this will move to a temperature of -22F (-30C). This 

mode is for use on large pieces where it is important to 

homogenise the chilling cycle.
In the case of SOFT or LIGHT temperature chilling, the 

set change will be decided by the product temperature 

detected according to the parameter (C2).
