5.0 DESCRIPTION OF CYCLES
5.1 NOTIONS ON BLAST CHILLING/BLAST FREEZING CYCLES
Soft Hard Freezing
Italiano
Soft blast chilling is employed to cool
the product quickly to a core temperature
of +3°C with a constant air tempera-
ture of -2°C
Ideal for delicate, lightweight and thin
products: food tem-perature is lowered
quickly but without damaging the
outside. The food can be stored for 5/6
days.
Whether dealing with products that are
cold or at room tem-perature, or products
that have just been cooked, blast chill-
ing time from +65°C to +3°C must not
exceed 90 minutes.
Hard blast chilling is employed to cool
the product quickly to a core temperature
of +3°C with negative air temperature
during the first stage (-35°C) and
positive temperature during the
second stage (0°C). Ideal for products
that are dense, have a high fat con-tent,
come in large portions or are hard to
cool. The food can be stored for 5/6
days.
Whether dealing with products that are
cold or at room tem-perature, or products
that have just been cooked, blast chill-
ing time from +65°C to +3°C must not
exceed 90 minutes.
Blast freezing is employed to freeze the
product quickly to a core temperature of
-18° with an air temperature of -38°C
Ideal for increasing storage life of food
(weeks or a few months), quick blast
freezing preserves the product's original
visual, aromatic and flavour properties,
and stops macro crystals forming,
keeping quality and texture intact.
Whether dealing with products that are
cold or at room temperature, or products
that have just been cooked, blast chilling
time from +65°C to - 18°C must not
exceed 240 minutes.

6.0 OPERATIONS
6.1 SWITCHING ON/OFF
Once you have turned on the appliance's power, the control panel (3.0) automatically runs a lamp test. The LEDs and
displays come on for a few seconds, after which the display switches "OFF" (control panel is off but still powered).
Switching on
Hold button down for a few seconds: the appliance goes into standby. During this phase, the machine stands by to
receive a command.
Display DY1 gives the temperature inside the appliance.
Display DY2 reads "---".
Switching off
Hold button down for a few seconds: the appliance switches "OFF".
Display DY1 reads "OFF".
Display DY2 stays off.
6.2 BLAST CHILLING/BLAST FREEZING
See points 7.0 and 8.0 for details.
6.3 OPENING THE DOOR WHILE A CYCLE IS RUNNING
If the door is opened while a blast chilling/blast freezing cycle is running, the "]-[" code will flash up intermittently on
display DY2 and, at the same time, a buzzer will sound. The compressor and fans inside stop and only restart once the
door is closed.
The blast chilling/blast freezing cycle cannot be started with the door open. If the door stays open for
longer than 30 seconds during the blast chilling/blast freezing cycle, the blast chilling
cycle is stopped.
6.4 PUMP DOWN
Pump-down is a system designed to protect the compressor and its job is to avoid excessive working pressures
during start-up.
Stopping the compressor
When button is pressed to stop a blast chilling, blast freezing or holding cycle manually, the compressor keeps
working for 5more seconds.
6.5 TEMPERATURE SENSOR AND NEEDLE PROBE READINGS
While a temperature-based cycle is running, DY1 indicates the value measured by the needle probe. You can
view compartment sensor temperature by pressing the button relating to the cycle selected: , or .
The value is put up on DY1 for 5seconds.
While a time-based cycle is running, DY1 indicates the value measured by the compartment sensor. You can view
needle probe temperature by pressing button . The value is put up on DY1 for 5seconds.
6.6 HEATED NEEDLE PROBE (Optional extra)
The heated needle probe (optional extra) has a device that heats its tip, making it easier to pull out of frozen products.
Holding button down for 5seconds at the end of a blast freezing cycle turns on heating so that the probe can be easily
removed from the frozen product. Heating only comes on if the door is open.
6.7 AUTOMATIC DEFROSTING
During operation, frost forms on the surface of the evaporator: this is normal but it reduces evaporator efficiency. The
purpose of defrosting is to restore full efficiency. Defrosting is performed automatically:
28

-At the end of each blast chilling/blast freezing cycle.
-At 6-hour intervals during holding.
The purpose of the evaporator sensor is to produce the utmost efficiency and shorten defrosting times by measuring the
end-of-defrosting temperature.
6.8 MANUAL DEFROSTING
This mode should be used only when further defrosting is required in addition to that performed
automatically by the appliance.
Shortcut commands while in standby mode
Make sure the appliance is working (6.1).
Hold button down for 5seconds.
The led by the button comes on, and goes off when cycle ends.
The defrosting cycle stops automatically. How long it takes depends on how much frost there is on the evaporator
coil.
Once defrosting has finished, the appliance resumes normal operation.

Core temperature probe
To achieve best operation, the needle probe must be positioned in the centre of the
product.
Make sure the probe tip does not poke through the product or touch the pan.
Do not insert the probe into food at temperatures exceeding 100 ° C to avoid
damaging the sensor. Leave the first diluting the product for a few minutes in
ambient.
Arranging products on pans
Use shallow pans so that the product surface has better contact with the air.
Arrange the products not overlapping on each other.
Filling the unit
Leave at least a 2cm gap between one pan and the next so as to allow
sufficient airflow.
Do not cover containers with lids of any kind.
Distributing pans
When the unit is being partially filled, spread the pans out evenly so that they use the
full height.
Do not leave hot products inside the compartment without running the cycle.
