During or at the end of blast chilling and freezing cycles, open the door slowly until the fans stop.
Extract carefully the core probe from the product and position it on the probe-holder.
Use suitable gloves for cold trays.
6.1 DANGER IN USE OF THE CORE PROBE
The use of the probe is allowed only for authorized and trained personnel.
The core probe must be used only for the purpose for which it was designed: to detect the
temperatures at the center of the food products to be chilled and/or frozen.
Handle the probe with care. It’s extremity is sharp to facilitate its insertion in products to be
chilled and/or frozen.
7-GENERAL ADVICE FOR USE
• Pre-cooling before a cycle of blast chilling or freezing, allows to reduce work time and obtain better
results
• Do not leave the hot product inside the chamber while not running a cycle, in order to avoid
damages to the machine.
• As soon as the product to be treated is inserted, start the blast chilling /freezing cycle.

950LIB055
Blast Chillers
• The core probe shall be positioned at the center of the largest cut of the product.
Make sure that the point of the probe does not come out of the product or touch the tray.
The probe must be cleaned and sanitized before each work cycle in order to avoid unwanted
contamination. Correct use of the core probe allows to reduce cycles duration and power
absorption.
• Do not overload the machine beyond manufacturer specication. If not at full load, it’s preferable to
place trays in the middle area of the chamber as close as possible to the evaporator fan.
Distribute the product neatly on the trays to allow the best possible air-flow around the product
surface.
• In order to obtain better results, load the trays with product with a maximum thickness of 8 cm for
blast chilling, or 5 cm for blast freezing. For difcult products characterized by a large quantity of
fats, reduce thickness.
• Do not leave cooked food to be blast chilled/frozen remain for long at room temperature. Start the
blast chilling /freezing as soon as preparation is completed.
• Cooked food can go inside the blast chiller even at temperatures beyond 100°C, as long as the
chamber is pre-cooled.
• Blast chilled and/or shock frozen food must be protected with hermetic cover or even better,
vacuum-packed. Indelibly mark the product with a label where content, day of preparation and the
expiration date are listed.

9.5 MANAGEMENT OF THE TEST REGARDING THE CORRECT INSERTION OF THE
CORE PROBE
Temperature-controlled cycles are preceded by a 2- phase test for the verication of the correct
insertion of the needle probe.
The second phase is only performed if the rst is not completed successfully.
The rst phase is completed successfully if the “temperature detected by the needle probe –
chamber temperature” difference is greater than 5°C in at least 3 controls out of 5 (the controls
are performed at 10 seconds intervals, consider the difference without sign).
The second phase is completed successfully if the “temperature detected by the needle probe
– chamber temperature” difference is 1°C higher with respect to the previous control in at
least 6 controls out of 8 (the controls are performed every 8 seconds). If the test is completed
successfully, the cycle will be started; if the test is not completed successfully, the LED
will flash and the buzzer will be activated for 2 seconds.
To start the temperature-controlled cycle, press the BLAST CHILLING key or the DEEP-
FREEZING key.
After 1 min from the signal that the test has not been completed successfully without having
operated, the cycle is started with time control.
9.6 PRE-COOLING START-UP
Every operating cycle can be preceded by pre-cooling.
Operate as indicated to start pre-cooling:
• Make sure the device is in the “on” status.
• Make sure no procedures are in progress
• Hold the BLAST CHILLING key down for 1 s: the LED will flash.
Operate as indicated to cut-off pre-cooling:
• Hold the BLAST CHILLING key for 1 second or start an operating cycle.
When the cabinet temperature reaches 5°C, pre-cooling continues, the LED remains on
permanently and the buzzer is activated for 1 s.
9.7 SWITCHING THE OZONE SANITIZATION CYCLE
(Only for models with Ozone Sanitization option)
Operate as follows:
• Make sure the device is in the “on” status and that the door is closed.
• Make sure that the keyboard is not locked and that no procedure is in progress.
• Hold the AUXILIARY key down for 1 s: the AUX LED will switch on.
The ozone generator is switched on for 5 minutes; opening the door cause the generator to
switch off
9.8 CORE PROBE HEATING
(Only for models with Heated Core Probe option)
Operate as follows:
• Make sure the device is in the “on” status or storage is in progress and that the door is open,
• Make sure that the keyboard is not locked and that no procedure is in progress.
• Hold the AUXILIARY key down for 1 s: the LED flashes and the AUX LED will switch on.
Core Probe is heated until the temperature detected by the needle probe reaches 40°C; closing
the door causes heating to be cut-off.
The buzzer is activated for 1 second on conclusion of heating.

10-SUGGESTION FOR A CORRECT USE OF THE BLAST CHILLER
10.1 SUGGESTION ON USE
Before using the blast chiller, clean deeply the inner cell, racks and the core probe.
10.2 PRE-COOLING
Before using the blast chiller for the rst time, and/or after a long period of inactivity, it’s
recommended to use the pre-cooling program and then start the desidered cycle after the
machine reached the working temperature.
10.3 LOAD OF THE BLAST CHILLER
It’s important to follow some guidelines in order to obtain a good performance from the unit and
avoid alteration of the stored food:
• Position the product in order to achieve an optimal air flow in the whole cell.
• If possible, avoid frequent and/or prolonged opening of the door while a cycle is running.
• Portion the food so that the tichkness is no more than 60-80 mm and the product are not
stacked to each other.
• Do not overload the racks more than the weight established from the constructor (see page 2
of this manual)
• Check the space between the trays is enough to guarantee a good air flow.
• Evenly distribute the product on all available trays.
• Check the trays are close to the evaporator grids for obtain a better and faster result

• The core probe must be correctly positioned at the centre of the heavier or greater piece of
product, be carefull that the tip of the core probe does not get out of the chunk and/or touch
the tray. The core probe should be cleaned at every cycle to prevent contamination of food.
• Do not cover the trays,do not use closed recipients and/or plastic lms, in order to avoid cycle
time increase and condensate formation. Use of vacuum bags do not affect the nal result.
11-”HACCP” FUNCTION (if supported)
Using the “HACCP” function, it is possible to memorize up to 9 events for each of the 3 HACCP
alarms, after which the most recent event overwrites the oldest.
