Technical Information 

Section 2

Once the cycle to change the duration of the SOFT phase 

is started (never greater than the parameter C4) simply 

press the button (3) which will show on the display (19) 

the wording “Soft” and on the display (18) the value in 

minutes of the SOFT phase. With the +/- buttons, it is 

possible to increase or decrease this value and confirm it 

with the button (3) or wait 5 seconds (N.B. THE CHANGED 

VALUE ONLY APPLIES TO THE CYCLE IN PROGRESS).
In the case of temperature chilling, the set changes will 

be decided by the product temperature detected (see 

paramerer cd).

“HARD” -3 LEDs on (Default)

In this condition and in the absence of adjustments 0.10V 

of the compressor, there will be a set cell temperature of 

-40°F (-40°C). This set accelerates the freezing process in 

the presence of products that do not require particular 

preperation.

“RUN” -4 LEDs on flashing

In this condition and in the absence of adjustments 0.10V 

of the compressor, there will be a set cell temperature of 

-40°F (-40°C). This set accelerates the freezing process in 

the presence of products that do not require particular 

preperation. In this case then the deep-freezing cycle will 

be continuous without moving into storage. The move 

to storage will be performed by pressing the button (3) 

and reducing the LEDs from 4 to 3. That process should 

be used in continous insertion and extraction condition 

produced by the blast chiller. 
During negative chilling, the compressor stops when the 

air temperature reaches the planned set point. In this 

cycle there will NOT BE automatic defrosting.

- Probes value reading

With the cycle in progress, pressing the button (12) will 

chow in sequence, after the cell probe value, the values 

of the insert probe 1 and 2 and the evaperator probe in 

flashing mode on the display (18) while on the display (19) 

will appear the wording in sequence of SP1, SP2 and SE 

that represent the type of probe being displayed.

7.5 - Storage phase

Storage always takes over and automatically after every 

chilling event (apart from the negative RUN+HARD 

exception) and keeps the product at the storage 

temperature of 35.6°F (2°C) or -13°F (-25°C), depending on 

the typre of chilling.
These values will be editable in all cases by pressing 

the button (2) or (3). It is possible to change during the 

storage phase the temperature set which appears flashing 

on the display (18), while on the display (19) the wording 

SET appears. To adjust the value (within 6 seconds) press 

the b/-. 

8 - DEFROST MODE

“Gas-hot” or “air” defrosting takes place:
- in automatic mode only during the storage phase and 

with a default time of 8 hours that is editable - or -
- manually both with machine in storage and with machine 

in STOP (not during chilling) by pressing the defrost 

button (13). All defrosting in progress can be interupted 

by pressing the defrost button.
Duration of the defrost cycle is given by reaching the 

defrost end temp measured by the evaporator probe; 

there is in any case a maximum length for defrost after 

which defrosting ends automatically.
Whenever possible, namely during the cycles of chilling, 

of ice-cream hardening, of storage, defrosting in storage 

and defrosting at machine standstill, it is possible to view 

the evaporator probe temperature by pressing the button 

(12): the display will show fo r5 seconds the wording “S.EV 

+ valore”.
Manual defrosts cannot be activated in the event that 

the value of the evaporator probe is higher than a certain 

temperature value, in which case a series of beeps will be 

emitted to alert the user to the fact that it is not possible 

to defrost and the wording “NoDefrost” will appear for 5 

seconds.

9 - DRYING WITH MACHINE AT STANDSTILL

When the machine is stopped by pressing the button (13) 

for more than 3 seconds, ventilation will be activated for 

a maximum time of 20 minutes (either with door open 

or closed). During this function the LED flashes and the 

display shows the scrolling text “Air Defrost”. To exit from 

this function press (short press) the defrost button (13). 

This mode is used when the machine is at a standstill for 

air defrost  or to dry the machine after cleaning.

10 - DOOR OPENING

When the machine is running (chilling, storage, defrost), 

the door is opened, the display shows the scrolling text 

“DOOR OPEN” every 5 seconds, alternating with the value 

read, and the beeper emits beeps. 
When closing the door, the fan starts without delays.
If the machine is running the door remains open for 

more than 5 minutes, the fan does NOT start again. The 

compressor is also locked and the open door alarm is 

given. Door reclosing, resetting of the audible alarm, 

visual and alarm relay.
If the door is opened while the machine is in “stop” the 

beeper does not sound but the appearance of the wording 

DOOR OPEN continues.
