against short circuiting and overloads.

• Compressor heat relay: intervenes in the

event of overloads or operating faults.

• Safety pressure switch: intervenes in the

event of excessive pressure in the refrig-

erant circuit.

• Plug fuses: intervene in the event of over-

pressure or operating fault in the safety

pressure switch (see above).

• Chamber temperature control: operated

by the electronic board by means of a

probe inside the cell.

• Temperature control end defrost cycle:

controlled by the electronic board by

means of the probe in the evaporator.

2.9 Dis osal of waste electronic

and electrical equi ment (WEEE)

Fulfilling Directives 2002/95/CE,

2002/96/CE and 2003/108/CE on the dis o-

sal of waste electronic and electrical

equi ment.

The crossed out wheeled bin sym-

bol indicates the product must be

collected separately from other

waste when it has become redun-

dant. Differentiated collection of

this equipment is arranged and

handled by themanufacturer.

Consequently, the user who is wanting to

dispose of this equipment must contact the

manufacturer and follow the method the lat-

ter has adopted to allow separate collection

of the redundant equipment.

Appropriate differentiated collection for the

subsequent recycling, treatment and eco-

friendly disposal of the dismantled equip-

ment prevents possible negative effects on

the environment and health and facilitates

the recycling of materials used in manufactu-

ring the equipment.

Administrative sanctions foreseen by the

regulations in force shall be applied for any

abusive disposal of the product by the hol-

der.

3. ADVICE TO ENSURE EFFICIENT APPLIANCE OPERATION

3.1 Shut-down procedures

In the event of emergency, shut down the

appliance by switching off power at the

main panel, by means of the knife switch or

by removing the plug from the power sock-

et.

3.2 Operating tips

Before starting up the appliance, clean the

inside of the cell thoroughly.

3.2.1 Pre-cooling

Before using the appliance for the first

time, or after a prolonged period of disuse,

pre-cool the cell by running an empty

cycle until the set operating temperature

has been reached.

To ensure optimal performance without any

alteration to food quality: arrange food

products in such a way as to favour the cir-

culation of cold air throughout the cell;

open the door

as little as possible.

3.2.2 Loading the appliance

a) Ensure that foods to be chilled and/or

frozen are separate and do not have a

thickness greater than 50-80 mm. Do

not load the appliance beyond the

quantity recommended by the manufac-

turer.

b) Ensure that there is sufficient clearance

between trays to enable free air circula-

tion.

If the appliance is not completely full,

distribute the trays and foods evenly

throughout the available space.

c) Position trays inside the tray compart-

ment as far as they will go, as close as

possible to the evaporator.

d) Position the core probe at the centre of

the largest product or food item; make

sure that the tip of the probe does not

protrude or touch the tray.

The probe must be cleaned and sani-

tised before each new cycle (operation)

to prevent inadvertent contamination.

e) Avoid covering the trays and/or contain-

ers with insulating covers or film. The

more the product is insulated, the more

time is required for chilling or freezing.

Trays must be packaged when the prod-

uct has been chilled, before being

placed in storage.

Delayed start of compressor during first starting

(for models E15-40 / E15-65 / E15.2-70)

Pre-heating f nction of compressor s mp

When the board is reached by mins tension, a 2-hour pre-heating phase starts and the display

shows some blinking dashes “---”. During this phase the machine cannot be started.

NOTE

The delayed start takes place only if the machine is given power by its dedicated magne-

tothermic switch.

It is therefore advisable that, after first starting, the machineis started or stopped by using the

control panel pushbutton. This way, the compressor pre-heating function is guaranteed, and the

machine starting takes place in a direct way.

Initial pre-heating is necessary in order to safeguard the compressor’s life. Only if strictly neces-

sary (and under the customer’s responsability) it is possible to by-pass countdown by pressing

the pushbutton “printer/HACCP” for about 5 seconds

5.1 STARTING UP THE APPLIANCE

When the appliance is powered up, it can be:

• ON displays 15 and 16 and left LED 5A on push-button 5 on,

LED 1 off

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

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

Whenever the appliance switches from STAND-BY status to ON, a self-test is carried out: all

LEDs and displays are switched on, push-buttons are checked, then the installed software ver-

sion is displayed.

OPERATION

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

• SOFT BLAST CHILLING (+3°C)

Pre-cooked food is rapidly chilled (90’) to a temperature of +3 C, thus preventing prolifera-

tion 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.

• HARD BLAST CHILLING (+3°C)

This process is designed to cool food products with a thickness greater than 2-3 cm. Variable

air temperatures are used to accelerate penetration of cold into the product.

This f nction is not activated if machine stops/starts operating d e to lack of power

d ring working cicle.

• BLAST FREEZING (-18°C)

This function freezes the product completely to a temperature of -18 C in less than 4 hours.

The rapidity of the process prevents formation of macrocrystals essential to ensure that the

product retains its original consistency and quality when thawed for consumption.

• AUTOMATIC CONSERVATION

At the end of each cycle (chilling or freezing), the appliance will automatically switch to the

required storage temperature.

Two different end-cycle modes are available for each 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 off)

5.2 SOFT BLAST CHILLING BY TEMPERATURE (pre-cooked, hot foods)

• To select this cycle, press push-button 2 (relative LED lights up), then press push-but-

ton 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.

• Display 15 indicates 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 16 .

• The instrument timer starts the countdown of the maximum blast chilling time as soon as the

temperature measured by the core probe falls below the temperature of +65 C (the dot at

the bottom right of display 15 flashes).

• During the blast chilling cycle, the air temperature is around 0 C.

This function is designed to guarantee uniform cooling of the product, preventing frost for-

mation on the surfaces. During the blast chilling cycle, the compressor may therefore stop

and restart, depending on the reading of the cell temperature probe.

• The blast chilling phase ends only when the core probe (inserted in the product core) indi-

cates that the set blast chilling temperature (+3 C) has been reached as signalled by an

intermittent beep for a minute. During the beep, LEDs 13 and 14 flash.

Display 16 indicates the temperature inside the cell, while display 15 shows

blast chilling time reset to zero.

• If at the end of the maximum blast chilling interval the core probe continues to display a tem-

perature 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; dis-

play 15 counts back the minutes remaining until the end of the cycle.

NB: Press push-button 8to mute the alarm; press push-button again to clear the

alarm display

• At the end of the chilling cycle, the appliance automatically switches to the set storage tem-

perature for an indefinite interval (like a standard storage appliance).

NB: LEDs 13 switch off while LEDs 14 light up.

• The cell temperature is constantly shown on display 16 ; during this cycle, defrost

cycles are performed at regular intervals with duration set as required (parameter pro-

gramming reserved for installation technician). The factory setting for positive storage tem-

perature is +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.

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 15 shows the maximum chilling time (set by

default to 90 minutes).

To modify this time, press push-buttons 7 and 8 (time in minutes).

• Press push-button 6 to start the appliance. LED 5B and push-button LEDs remain

on and LEDs 13 flash throughout the cycle.

• Internal cell temperature is shown on display 16 .

• 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 indefi-

nite 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 push-button 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 0 C in order to

accelerate chilling;

• a second “Soft” stage, involving air temperatures around 0 C.

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.

• Display 15 indicates 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 16 .

• The instrument timer starts the countdown of the maximum blast chilling time as soon as the

temperature measured by the core probe falls below the temperature of +65 C (the dot at

the bottom right of display 15 flashes).

• Once the cycle has been started, the appliance operates initially with an air temperature

below 0 C (LED on push-button 3 flashes), then with temperatures around 0 C (LED on

push-button 3 on).

NB: The first stage of the cycle is completed when the core probe detects a temperature of

+20 C in the product core.

• The blast chilling phase ends only when the core probe (inserted in the product core) indi-

cates that the set blast chilling temperature (+3 C) has been reached as signalled by an

intermittent beep for a minute. During the beep, LEDs 13 and 14 flash.

Display 16 indicates the temperature inside the cell, while display 15 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 foodstuffs with a high fat content, for large pieces or for packaged products.

SOFT chilling is recommended for delicate and finely chopped products, such as vegetables,

mousses, etc..

5.5 HARD TIMED BLAST CHILLING

• To select this cycle, press push-button 3 (relative LED lights up), then press push-but-

ton 5 to select the “timed” mode (LED 5B on). Display 15 shows the max-

imum chilling time (set by default to 90 minutes).

• 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 16 .

• Once the cycle has been started, the appliance operates initially with an air temperature

below 0 C (LED on push-button 3 flashes), then with temperatures around 0 C (LED on

push-button 3 on). For example: HARD timed chilling cycle 90 minutes. First stage of

40 minutes with negative air temperature. Second cycle stage of 50 minutes with air tem-

perature around 0 C.

• 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 indefi-

nite 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.
