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 two­phase cycle:

• Chilling phase (limited duration)

• Storage phase (unlimited period)

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.

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.

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

“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

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).

Part Number: 9294045 07/19 13

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 buttons +/-.

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.

Section 2 Technical Information

11  OZONATOR

This function is only available when the machine is
stopped and is activated by pressing the ozonation
button (12) (the LED of the button comes on) . The ozone
is released for 120 minutes after which the release ends
(the LED goes off). At the same time as the Ozonator the
fan is also activated to facilitate movement.

During the sterilisation cycle the word “Ozone” will
flash on the display (18) and the display (19) will show
the countdown of the cycle time. If the door is opened
during the 120 minutes, the sterilisation cycle will stop
IMMEDIATELY; it will not even start upon closing of the
door, and the scrolling text “STOP Ozone Cycle” will appear
for 5 seconds. If the ozonator is not installed the scrolling
text “Ozone Not Present - Ozone non presente” will appear
on the display for 10 seconds.

12  ICECREAM CYCLE

This cycle enables the user to use the chiller in negative
chiller mode with a Timer that schedules the introduction
and extraction of ice-cream containers, allowing the
surfaces to harden, after leaving the ice-cream making
machine.

With the machine in stop mode, press the “ice-cream”
button (10); the beeper will emit a beep and the LED of
the button will start to flash. The negative chilling cycle
will start immediately (to cool the machine), the display
(19) of the time will show the flashing cycle time while
the display (18) will indecate the tempetature of the cell
probe.

The user has the option,n at this point, to modify the time
of the hardening cycle by pressing the “+” and “-”, and to
confirm the time by pressing the “ice-cream” button (10).

After this setting when the user opens the door (to
introduce the ice-cream) and then reclose it, a beep is
emitted as comfirmation and the countdown will start.
When the time reaches zero, the beeper will sound for
60 seconds, and the sliding text “carica gelato - charge
ice cream” will appear. Then whenever the door is closed,
any countdown in progress is interrupted and a new one
starts.

During the cycle the user may at any time change the time
and the temperature set as default as follows:

1) by pressing the “ice-cream” button (10), with the first
time press the time on the display (19) will flash and it can
be changed with the +/- buttons.

2) the next press of the button (10) will acquire the new
value.

3) now using the buttons +/- it is possible to chance the

flashing set represented on the display (18) with a value
that can range from the minimum value to a maximum
one (this theoretically allows setting of the long softening
cycles for ice-cream which, extracted from the storage
machine, must be placed on display.)

4) pressing the button (10) allows saving of the new value
followed by the return to the cycle.

The user can stop this cycle at ay time by pressing the
START/STOP button (22).

13  THAWING CYCLE

This function aims to safely thaw (below 50°F (10°C)
of temperature cell) previously frozen or deep-frozen
products. The process is based both on cell temperature
control, with a positive value between 38°F (3°C) and 50°F
(10°C) average, and on the action of forced ventilation.

When the machine is stopped, select the thawing cycle by
pressing the button (15); the cycle will start immediately
showing on the “display 19” the standard thawing time
and on “display 18” the measured cell temperature.

To change the values of time and temperature set, simply
press the button (15) until the display flashes which
will present the time value set. With the +/- buttons it is
possible to modify the thawing time. With the modification
completed with the +/- buttons it is possible to change
the SET which will be confirmed by pressing the button (5)
or by waiting 5 seconds.

The the temperature set value flashes on the display (8)
which can also be changed with the +/- buttons. With
the modification completed with the +/- buttons (6) it is
possible to change the SET by pressing the button (3) or
by waiting 5 seconds.

Then on the display, if VE2 is different from 100, the
wording “HARD FANS” will be represented (if fan
regulation is enabled). To confirm press the button (5),
while to change press the +/- buttons until appearance
of the second option “SOFT FANS” (reduced evaporator
fan speed); pressing the button (5) the value selected is
confirmed.

After this operation, the cycle in fuction is resumed which
when finished will activate the beeper and the scrolling
text “End Cycle - Fine Ciclo” will appear. At that time the
cycle will go into storage.

To see the value of the insert probe during thawing, simply
press the button (12) which will display the product probe
value for 5 seconds flashing on the display (18) and the
wording “SP1” and “SP2” is shown on the display (19) to
distinguish the probe reading.

14  CHILLING PROGRAM STORAGE

The user has the button (16), which allows the saving or
recalling of 99 chilling cycles.

To store a chilling cycle the user must:

1) set a chilling type (button 1 - 2)

2) set the mode of chilling (by temperature or by time,
button (5))

3) set the total time or the final temperature +/- buttons.

4) press and hold (long press) the “PROGRAM” button
(16) until the beeper emits a beep; the LED of the button
starts to flash. On the basis of the first display it will flash
signifying waiting for setting of the first letter/number.

5) then using the keys +/- set the first letter/number and
confirm with the button (5). This will confirm the value,
passing on to the next one. Arriving at the ninth character
or even before, it is possible to press the START button for
start and storage (ATTENTION, if a program with the same
name already exists, it will be overwritten.)

6) press START/STP (22)

With Start the software stores the “type” and “mode” of the
chilling selected.

To discontinue saving of the program, press the storage
button again or wait for the TimeOut (approximately 10
seconds). If time chilling has been set, the duration set is
stored.

In the case of temperature chilling, it will store the
time in which the insert probe reaches the PRODUCT
TEMPERATURE SET, and will store this time as durtion of
chilling.

In addition, if the chilling is Positive Hard, it also saves the
time necessary to reach the core at 68°F (20°C) (Hard).

When saving a temperature (insert probe) chilling cycle,
the LED of the programming button flashes to indicate
that storage of the times is in progress. As soon as the
temperature chiling cycle ends, the LED stops flashing to
indicate that storage has been successful.

If storing a temperature cycle, this stops (due to alarms,
button stop, etc.), the cycle times are not saved. The initial
settings however remain saved.

15  CHILLING PROGRAM EXECUTION

To call up and run a memory-resident program, the user
must:

1) press the “PROG” button (short press), the LED lights up
and with the +/- buttons, select one of the saved programs.

2) press START

If the save button is pressed by accident, pressing it again
will exit that function.

While a program is running, by pressing the “PROG” button
the display shows the name of the program in progress.

20.1 Operations by the user that do not require the

assistance of a qualified technician

20.1.1 - Cell cleaning

In order to ensure hygiene and protection of the quality
of the food being processed, interal cleaning of the cell
must be performed frequently, depending on the type of
food stored.

Suggested frequency: weekly cleaning.

- The shape of the cell and of the internal components
allow its cleaning using a cloth or sponge.

- Clean with water and non-abrasive neutral detergents.

Rinsing is possible with a cloth or sponge soaked in water
or with a moderate water jet (not exceeding the system
pressure). Do not scrape the surfaces with sharp or
abrasive items.

20.1.2 - Outer casing cleaning

For cleaning of the casing simply use a cloth dampened
with a chlorine-free product, suitable for stainless steel.

20.1.3 - Defrost water drainage

20.2 - Operations only for authorised installer

Below are listed the routine maintenance operations
that must only be performed by qualified installation
techinicians. The manufacturer declines all liability
for accidents caused by non-compliance with the
requirement.

Below is a list of operations useful to preserve the efficient
operation of the appliance with related recommended
frequencies.

Detailed maintenance operations are described in the
Service Manual kept by installers and qualified technicials.

20.2.1 - Condenser cleaning

(for air cooled models only)

For the correct and efficient operation of the condenser,

the air cooled condenser must be kept clean to allow the
circulation of air.

Recommended frequency: operation to be performed
every 30 days or in any case according to the working
condintions of the appliance (the presence of dust and
flour in the work environment of the appliance significantly
affects dirt accumulation of the condenser thus making it
less efficient).

20.2.2 - Condenser filter cleaning

(for air cooled models only)

Recommended frequency: operation to be performed
every 30 days or in any case according to the working
condintions of the appliance (the presence of dust and
flour in the work environment of the appliance significantly
affects dirt accumulation of the condenser thus making it
less efficient).

20.2.3 - Evaporator cleaning

For the correct and efficient operation of the appliance,
the evaporator battery must be kept clean to allow free
air circulation and especially to remove food residue and
grease the can be a source of bacteria harmful to human
health.

Suggested frequency: operation to be performed every 30
days or depending on the type of food being processed.

20.2.4 - Ozonator maintenance

Dirty and dusty environments reduce efficiency of the
ozonator: for longer lamp life and for greater efficiency,
the bulb of the ozonator should be cleaned periodically. To
ensure maximum fucntionality the bulb must be replaced
every 12 months.

For the correct maintenance and cleaning practices
comply with the instructions in the service manual.

Suggested frequency: clean the lamp of the ozonator at
least every 3 months.

Replacement of the lamp every 12 months (only genuine
spare parts).

21  TIPS FOR SMOOTH OPERATION

21.1 - Operating instructions

Before operating the machine it is necessary to perform
thorough cleaning inside the cell.

21.2 - Pre-cooling

Before using the machine for the first time or after a period
of disuse. pre-cool the cell by running the machine empty
until it reaches the working temperature set.

To obtain good performance of the machine and to aviod
food alterations, it is advisable to:

• stack the products in order to promote the

21.4 - How to load the machine

A) In order to grant chilling/freezing time ensure that food
to be chilled/frozen in seperated pieces (max thinkness
2”/50mm).

B) Ensure a sufficient distance is maintained between the
trays to allow adequate air circulation.

If the machine is not completely loaded, distribute the
trays and the load over the entire useful height avoiding
concentrations.

A

D) The core probe must be positioned correctly in the
center of the product with the largest cut or piece, making
sure that the tip of the probe does not protrude out or
touch the tray. The probe must be cleaned and sanitised
before each new cycle (work) in order to avoid undesirable
contamination.

D

E) Do not cover the trays and/or container with lids or
insulating films: the more the food is insulated the greater
the time required for chilling and rapid freezing.

Packaging of the trays must be performed when the
product is already frozen, before it is put into storage.

PROGRAMMING AND OPERATING INSTRUCTIONS

Starting up the Appliance
Preheating function of compressor

When power is initially supplied to the cabinet, a 2 hour
pre-heating phase starts and the display shows some
blinking dashes. During this phase the machine cannot be
started. This important information is shown on a yellow
label placed inside the door.

Initial pre-heating is necessary in order to safeguard the
compressors life. Only if strictly necessary (and under
the customer’s responsibility) is it possible to by-pass
countdown by pressing the button “Printer/HACCP” for
roughly 5 seconds.

This function is not activated if machine stops/starts
operating due to lack of power during working cycle.

When the appliance is powered up, it can be:

- ON: displays icon 14, 15 and left LED 5A

- OFF - STAND-BY LED: on push-button 1

To switch from one status to another, press push-button 1.

Whenever the appliance switches from STAND-BY status
to ON, a self-test as carried out: all LEDs and displays are
switched on, push-buttons are checked, then the installed
software version is displayed.

OPERATION

The main work cycles (chilling/freezing) performed by the
appliance.

- SOFT BLAST CHILLING (38°F / 3°C)

Pre-cooked food is rapidly chilled (90) to a temperature
of 38°F / 3°C, thus preventing proliferation of bacteria
and preventing dehydration of the cooked food due to
evaporation. Food can thus be stored perfectly for 5 to 7
days without altering its original qualities. The soft cycle
is recommended for delicate, thin foods such as rice,
vegetables and fried foods.

- HARD BLAST CHILLING (38°F / 3°C)

This process is designed to cool food products with a
thickness greater than 2.3cm / 1” and is very effective
for dense, greasy or large-sized foods. Variable air
temperatures are used to accelerate penetration of cold
into the product.

- BLAST FREEZING (0°F / -18°C)

This function freezes the product completely to a
temperature of 0°F / -18°C in approximately 4 hours. The
rapidity of the process prevents formation of macrocrystals
essential to ensure that the product retains its original

consistancy and quality when thawed for consumption.

- AUTOMATIC CONSERVATION

At the end of cycle (chilling and freezing), the appliance will
automatically switch to the required storage temperature.

Two different end-cycle modes are available for cycle:

- BY TEMPERATURE - the cycle ends when the probe
reaches the required temperature.

- TIMED - cycle length is pre-set.

IMPORTANT: work cycles and modes can only be selected
when the appliance is ON (LED on push-button 6)

5.2 SOFT BLAST CHILLING BY TEMPERATURE (pre­cooked, hot foods)

- To select this cycle, press push-button 2, then press push­button 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 relatedto the push-buttons pressed illuminate
throughout the cycle, while LEDs 12 flash.

- Display 14 indecates the maximum blast chilling
time (starting temperature to end of the blast chilling
temperature (factory setting 90 minutes).

- The temperature measured by the core probe is shown
by display 15.

- The instrument timer starts the countdown of the
maximum blast chiling time as soon as the temperature
measured by the core probe falls below the temperature
of 149°F / 65°C (the dot at the bottom right of display 14
flashes.)

- During the blast chilling cycle, the air temperature is
around 32°F / 0°C and may gets as low as 23°F / 5°C. This
function is designed to gaurantee uniform cooling of
the product, preventing frost formation on the surfaces.
During the blast chiling cycle, the compressor may
therefore stop and restart, depending on the reading of
the compartment temperature probe.

- The blast chilling phase ends only when the core probe
(inserted in the product core) indicates that the set blast
chilling temperature (38°F / 3°C)) has been reached as
signalled by an intermittent beep for a minute. During the

Part Number: 9294045 07/19 33

Troubleshooting Section 4

beep, LEDs 13 and 14 will flash. Display 15 indicates the
temperature inside the compartment, while display 14
shows blast chilling time reset to zero.

- If at the end of the maximum blast chilling interval the
core probe continues to display a temperature higher
than the value for the end of blast chilling, the displays
will indicate an alarm for excessively long chilling (ALL 14)
alternating with the temperature and time; at the same
time, the alarm beep will be activated.

The blast chilling cycle continues until the end chilling
temperature has been reached; display 14 counts back the
minutes remaining until the end of the cycle.

Press push-button 8 to mute the alarm; press push­button again to clear the alarm display.

- At the end of the chilling cycle, the appliance
automatically switches to the set storage temperature for
an indefinite interval (like a standard storage appliance).

regular intervals with duration set as required (parameter
programming reserved for installation technician). The
factory setting for positive storage temperature is 36°F /
2°C.

- Press push-button 6 to set the appliance to STOP status
(relative LED switches off), ready for a new cycle.

To modify the final blast chilling temperature, consult the
user programming instructions.

IMPORTANT: During chilling or shock freezing by core
sensor it’s possible to read:

- The room temperature by pressing push-button

- The evaporator temperature by pressing push-button

5.3 SOFT TIMED BLAST CHILLING

- Press push-button 2 (relative LED lights up), then press
push-button 5 to select the timer mode (LED 5B on).
Display 14 shows the maximum chilling time (set by
default to 90 minutes).

To modify the time, press push-button 7 and 8 (time in
minutes).

- Press push-button 6 to start the appliance. LED 5B and
push-button LEDs remain on the LEDs 13 flash throughout
the cycle.

Internal cell temperature is shown on display 15.

- When the maximum chilling time has counted back

to 0, the chilling cycle is completed and the appliance
automatically switches to the set positive storage
temperature for an indefinite interval.

- LEDs illuminate and the beep is activated when the cycle
is finished (as in the chilling cycle by temperature). The
same applies for the positive storage function. Press push­button 6 to set the appliance to STOP status (relative LED
switches off), ready for a new cycle.

IMPORTANT: Use the storage function sparingly. After
chilling, food products should be placed in storage
cabinets.

HARD BLAST CHILLING

When the HARD function is used, chilling takes place in
two stages:

- an initial “Hard” stage when the air temperature is
brought down to below 32°F / 0°C in order to accelerate
chilling;

- a second “Soft” stage, involving air temperatures around
32°F.

IMPORTANT: During chilling or shock freezing by time
it’s possible to read the evaporator temperature by
pressing push button.

5.4 HARD BLAST CHILLING BY TEMPERATURE

- Press push-button 3 (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 data is constantly stored on the internal recorder and
can be downloaded anytime from the internal recorder by
introducing a USB drive into the USB port on the machine.

Instructions to download the data:

1. Insert the USB drive.

IMPORTANT: wait until the LED of the USB drive
stops flashing, which means that all the data is
recorded on the USB drive.

2. Extract the USB drive.

3. On the USB drive you will find a file named lon00n000001.
txt which is a text file, delimited with ";" (semicolon).

Every time you insert the USB drive, a new log file will be
generated, with a progressive number (log00n000002.txt,
log00n000003.txt, etc).

Every file generated will contain the complete historical
data recorded, up to the moment of insertion of the USB
drive. As a consequence, the time to save the file on the USB
drive will increase from some seconds to several minutes,
depending on how much data is stored on the recorder.
