i All maintenance interventions that require
precise technical skill or particular ability must be
performed exclusively by qualified staff.
! When using the appliance, never obstruct the
air inlet when the appliance is on, so as not to
compromise its performance and safety.
! Never stretch the power cable.
In order to guarantee hygiene and protect the
foodstuffs from contamination, the elements that
come into direct or indirect contact with the
foodstuffs must be cleaned very well along with
the surrounding areas. These operations must
only be performed using detergents that can be
used with foodstuffs, avoiding inflammable
products or those that contain substances that are
harmful to personal health.
In the case of prolonged inactivity, as well as
disconnecting all the supply lines, it is necessary
to accurately clean all internal and external parts
of the appliance.
4.1. 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.
Door micro switch
If the door is opened,
the magnetic switch placed on the control board
opens and, during blast-chilling or shock-freezing,
evaporator fans go off and a warning message
appears on the display at the same time. This
condition may also be determined when the door
is not perfectly aligned to or near the control
board: in this case with machine in STOP phase,
cycle start-up is prevented, apart from start-up of
the defrosting cycle.
If a U.V. sterilisation cycle is active, the
functioning of the U.V. lamp is interrupted. The
cycle continues when the door is closed.
Protective Fuses
Some protection fuses in the general power
supply line are activated in case of overload.
High condensation temperature alarm
In the event of room
conditions or functional failures, which cause the
condenser to exceed the maximum temperature
value, an alarm is triggered and stops the
machine running. The machine can be run when
an acceptable temperature value is reset.
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.

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 so to
determine the necessary time for a correct
product blast chilling process. Do not forget that
acquired times and eventually memorised have to
be considered valid for exclusive use of the same
type of product and in the same quantities per
cycle.
Intensive timed blast chilling
For the use of this cycle, the information
contained in the previous paragraph is applicable
concerning the time which can be set and the final
temperature of the product.
The use of this function, which makes it possible
to reduce chilling times, is recommended for foods
with the following characteristics:
Ø Packaged foods or foods in containers
Ø Foods with a thickness greater than 50
mm
Ø Foods with a high fat content
Temperature Shock Freezing
This cycle allows a reduction in temperature in the
product core from +90°C to -18°C as quickly as
possible and within a MAX time of 270 minutes.
The cycle ends when the value -18°C, read by the
needle probe, is reached.
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 automatic test cycles so to
determine the necessary time for a correct
product blast chilling process. Do not forget that
acquired times and eventually memorised have to
be considered valid for exclusive use of the same
type of product and in the same quantities per
cycle.
SOFT Time Shock Freezing
The use of this function is recommended in the
presence of foodstuffs that fear a large initial heat
shock or foodstuffs with different ingredients as
composition (e.g.: fresh pasta) and therefore
require slower and homogeneous shock freezing.
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:
Ø + 3°C for blast chilling
Ø -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.

Recommendations for normal use
In order to ensure correct use of the appliance, it
is good practice 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.
áDo not insert foodstuffs that are well above
the temperature of 65°C. As well as initially
overloading the machine it can make protections
intervene that prolong temperature descent times.
If possible, a brief external period is useful to
lower the temperature to acceptable values.
Check the planarity of the appliance rest surface.
i 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.
i 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.
i Never obstruct the inlet of the evaporator
fans.
i Products that are more difficult to chill
because of their composition and size should be
placed in the centre.
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.
iAfter 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.
i The chiller should be used for storage for
short periods only.
! 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.

i 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 cycle
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).
i Intensive Blast Chilling Cycle
With this operating mode, at the beginning the
chiller maintains the temperature of the
refrigerating compartment at a much lower than
the value set for normal chilling, in order to
accelerate the drop in temperature of the product.
When the product reaches the fixed temperature
(temperature at which ice could form on the
external surface product) the internal temperature
of the compartment rises to the temperature set
for normal positive chilling. This blast chilling
method should be used preferably for products
that are packed and whose physical/organoleptic
characteristics are not damaged by the formation
of superficial ice.
i Shock freezing Cycle
With this chilling modality the chiller maintains the
temperature value in the compartment 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.
i Shock freezing Cycle SOFT
In this case, the shock freezing cycle is divided in
two phases that differ depending on the
compartment set point used. The first phase
consists in a cycle around the compartment set
point defined for normal blast chilling. The
passage to the second phase starts when the
core-probe reaches a pre-defined temperature
exchange value or when the time elapsed is equal
to a pre-set percentage of the total time. In the
second phase, the compartment reference set
point will be the same as the shock freezing one.
This type of shock freezing allows a more even
freezing of the product, avoiding the external
formation of ice when the core temperature is still
high.
6. CLEANING AND MAINTENANCE
6.1. Recommendations for Cleaning and Maintenance
! Activate all envisioned safety devices before
carrying out any maintenance interventions. In
particular, deactivate the electrical power supply
using the automatic isolating switch.
6.2. Routine Maintenance
Routine maintenance consists of daily cleaning of
all the parts which can come into contact with
foodstuffs and the periodic maintenance of the
burners, nozzles and draining pipes.
Correct maintenance allows the user to maximise
performance levels and operating life and
constantly maintain safety requirements.
Do not spray the appliance with direct jets of
water or using high pressure appliances.
Do not use iron wool, brushes or scrapers to clean
the stainless steel as ferrous particles could be
deposited which, on oxidising, could lead to rust.
To remove hardened residues, use wooden or
plastic spatulas or abrasive rubber pads.
During long periods of inactivity, spread a
protective layer on all stainless steel surfaces by
wiping them with a cloth soaked in Vaseline oil
and airing the rooms periodically.
! Do not use products which contain substances
which are harmful and dangerous for personal
health (solvents, petrol etc.).
At the end of the day it is advisable to clean:
Ø the cooling compartment
Ø the appliance.
