4.6. Safety Devices
During the running of appliance, some control
devices may activate and govern the correct
running of the machine. In other cases, they may
deactivate parts or the whole machine, to put the
appliance in safe conditions. Main controls are
described below.
Micro Door
In case the door is opened,
the magnetic switch placed on the control board
opens and, during blast-chilling or shock-freezing,
evaporator fans go off ; if the opening persist for a
longer period than the one established on
parameter i2, it will appear on the display the
alarm “id” together with a sound signal (until the
door is closed).
That condition may also be determined when the
door is not perfectly aligned to or near the control
board.
High pressure safety pressure switch
The alarm is represented on the display with the
code “HP”.
Protective Fuses
Some protection fuses in the general power
supply line are activated in case of overload.
Other fuses are prepared for the evaporator fans
Evaporator Fan Micro switch
If the deflector is opened to
inspect the evaporator or fans, this micro switch
positioned on the evaporator deflector,
deactivates machine functioning. Closure of the
deflector with the successive disappearance of
the alarm on the display, restores normal machine
functioning.
The alarm is represented on the display with the
code “HP”.
Electrical Power Supply Failure
In the event of room conditions
or functional anomalies, which cause the
refrigerating circuit to exceed the maximum
pressure values, the MAX safety switch is
activated, stopping the machine. When an
acceptable pressure value is reset, it is possible to
run the machine.
In the event of a power failure
during a working cycle for a period exceeding the
value established on parameter A10, once
restored the electricity the display will show the
alarm “PF”.

5. USE AND FUNCTIONING
5.1. Description of the Functioning Cycles
The following are brief descriptions and types of
operating cycles.
Temperature Blast Chilling
This cycle allows
a reduction in temperature in the product core
from +90°C to +3°C as quickly as possible and
within a MAX time of 90 minutes. The cycle ends
when the value +3°C, read by the needle probe, is
reached.
Time Blast Chilling
This cycle allows
a reduction in temperature in the product core
from +90°C to +3°C during the set time: we
remind you that it is advisable to run some
previous testing temperature cycles in order to
determine the necessary time for a correct
product blast chilling process. Do not forget that
acquired times have to be considered valid for
exclusive use of the same type of product and in
the same quantities per cycle.
Temperature Shock Freezing
This cycle allows
a reduction in temperature in the product core
from +90°C to -18°C in the quickest time possible
and within a MAX time equal to 270 minutes. The
cycle ends when the value -18°C, read by the
needle probe, is reached.
ENGLISH
Time Shock Freezing
This cycle allows
a reduction in temperature in the product core
from +90°C to -18°C during the set time: we
remind you that it is advisable to run some
previous testing temperature cycles in order to
determine the necessary time for a correct
product blast chilling process. Do not forget that
acquired times have to be considered valid for
exclusive use of the same type of product and in
the same quantities per cycle.
Preservation
At the end of each cycle as described above,
either temperature or time cycle, the preservation
cycle will be started automatically, with no time
limit. The freezer temperature will refer to last
cycle, just concluded:
+ 3°C for blast chilling
-25°C for shock-freezing
Warning: use of this cycle is recommended only
for short periods prior to storage of the product in
a storage unit or in case of emergency, so as to
avoid such a limited use of a machine with such
high potential.
Defrosting
The frost forming on the evaporator following the
deposit of humidity from the product can
jeopardise the correct functioning of the
appliance. A defrosting cycle must be carried out
to restore full functionality.
Defrosting is performed by forced ventilation using
the evaporator fan. The cycle can be performed
with the door open or closed and can also be
interrupted at any time.

of mould and/or unpleasant odours.
Recommendations for normal use
In order to ensure correct use of the appliance, it
is advisable to apply the following
recommendations.
! Do not obstruct the zone in front of the
condensing unit in order to favour heat disposal
from the condenser to a maximum.
Always keep the front of the condenser clean.

Do not stack the materials to be preserved
in contact with the internal walls, so blocking the
circulation of air, which guarantees uniformity of
the internal temperature of the refrigerated
compartment.
There must be a sufficient space between
the basins and trays used in order to guarantee a
sufficient flow of cold air on the entire product.
Therefore avoid the following positions of trays
and/or basins stated below.
Never obstruct the inlet of the evaporator
fans.
Products that are more difficult to chill
because of their composition and size should be
placed in the centre.
GB
Do not insert foodstuffs that are well above
the temperature of 90°C. As well as initially
overloading the machine it can make protections
intervene that prolong temperature descent times.
15
Page 17
ENGLISH
! To prevent bacterial contamination or
contamination of any other biological nature,
the needle probe must be disinfected after
use.
! To extract the product that has undergone
blast chilling or shock freezing, always wear
gloves to protect the hands, as "burns" may occur
from the cold.
GB
Limit the number of times and the duration of time
the doors are opened.
! Blast chilling data refer to standard products
(low fat content) with a thickness below 50 mm;
therefore avoid overlaying products or the
insertion of pieces with a much higher thickness.
This would, in fact, lead to an extension of blast
chilling times. Always distribute the product well
on the trays or basins or in the case of thick
pieces decrease the amount to blast chill.
After blast chilling/shock freezing the
product, it can be stored in a preservation cabinet
after having been duly protected. A tag should be
applied describing the contents of the product,
blast chilling/shock freezing date and expiry date.
When the product has been blast chilled it must
be preserved at a constant temperature of +2°C ,
while if it has been shock frozen it must be
preserved at a constant temperature of -20°C.
The chiller should be used for storage for
short periods only.
Blast chilling Cycle
With this operating modality the chiller keeps the
temperature of the refrigerating compartment
close to zero during the entire chilling process in
order to ensure a gradual drop in the temperature
of the product to +3°C. In this way, ice crystals do
not form on the surface of the product. This blast
chilling method should be used preferably for
products that are not packed and whose
physical/organoleptic characteristics could be
damaged by the formation of superficial ice (e.g.
fish).
Shock freezing Cycle
With this blast chilling modality the blast chiller
maintains the temperature at a negative value
below -18°C which is the end temperature of
shock freezing. For shock freezing to be
successful and fast, food should be in small
pieces, especially if it has a high fat content. The
largest pieces should be placed in central trays. If
it takes longer than standard time to shock freeze
and the sizes cannot be reduced, decrease the
quantity and precool the chiller compartment by
starting an empty shock freezing cycle before
shock freezing the product.
