Troubleshooting

temperature of 68°F / 20°C in the product core.
- The blast chilling phase ends only when the core probe 

(inserted in the product core) indicates that the set blast 

chillling temperature (38°F / 3°C) has been reached as 

signalled by an intermittent beep for a minute. During the 

beep, LEDs 13 and 14 will flash. 
Display 15 indicates the temperature inside the cell, while 

display 14 shows blast chilling time reset to zero.
- The alarm (ALL 14) and conservation functions cut in 

with relative indicators in the same way as for timed soft 

blast chilling. 
- Press push-button 6 to set the appliance to STOP status 

(relative LED switches off), ready for a new cycle.

IMPORTANT
HARD

 blast chilling affords a considerable reduction 

in working time, and is particularly suited to foods with 

a high fat content, for a large pieces or for packaged 

products.

SOFT

 chilling is recommended for delicate and finely 

chopped products, such as vegetables, mousses, etc..

IMPORTANT:

 During chilling or shock freezing by core 

sensor it’s possible to read:
- The evaporator temperature by pressing push button.

5.5 HARD TIMED BLAST CHILLING

- To select this cycle, press push-button 3 (relative LED 

lights up), then press push-button 5 to select the “timed” 

mode (LED 5B on). Display 14 shows the maximum chilling 

time (set by default to 90 minutes).
To modify this time, press push-button 7 and 8 (time in 

minutes).
- To set the time of the first negative temperature stage, 

press push-button 3 for five seconds, then wait for display 

14 to show the flashing value.
The time setting (in minutes) can be modifided by means 

of push-buttons 7 and 8. Press push-button 3 again to 

return to standard display.
- Start up the cycle by pressing push-button 6. LED 5B 

and push-button LEDs remain on and LEDs 13 flash 

throughout the cycle.
- Internal cell temperature is shown on display 15.
- 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 arounf 

32°F / 0°C (LED on push-button 3 on). For example: HARD 

timed chilling cycle 90 minutes. First stage of 40 minutes 

with negative air temperatue. Second cycle stage or 50 

minutes with air temperature around 32°F / 0°C.
- When the maximum chilling time has counted back 

to 0, the chilling cycle is completed and the appliance 

automatically switched to the set posoitive storage 

temperature for an indefinite interval.
- LEDs illuminate and the beep is activated when the cycle 

is finished (as in the temperature chilling cycle). The same 

applies for the storage function.
- Press push-button 6 to set the appliance to STOP status 

(relative LED switched off), ready for a new cycle. 

IMPORTANT: 

During chilling or shock freezing by time it’s 

possible to read the evaporator temperature by pressing 

push button.

5.6 BLAST FREEZING BY TEMPERATURE

- To select this cycle, press push-button 4 (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.
- The appliance proceeds to operate in the same way as 

that described for the positive chilling cycle. During this 

cycle the compressor operates in continuous mode to 

enable the appliance to reach the cycle end temperature 

in the shortest time possible (default temperature at 

product core is set at 0°F / -18°C). Maximumm freezing 

time is 240 minutes.
- The alarm (ALL 14) for excessively-long freezing and 

conservation functions cut in with relative indicators in 

the same way as for timed Soft blast chilling. The factory 

setting for negative storage temperature is -13°F / -25°C. 
- LEDs illuminate and the beep is activated when the cycle 

is finished (as in the soft chilling cycle by temperature). 

The same applies for the storage function. Press push-

button 6 to set the appliance to STOP status (relative LED 

switches off), ready for a new cycle.

IMPORTANT: 

During chilling or shock freezing by core 

sensor it’s possible to read:
- The evaporate temperature by pressing push button 10.
