Characteristics of the installation area
Install the device in areas:
- compliant with industrial food handling;
- with adequate ventilation;
-prepared with electrical and plumbing systems compliant with
the legal provisions in force in the country of use and according
to the workplace safety requirements in the country of use;
- with temperatures from +15° to +43°C;
- that are sheltered against the elements;
- with flooring able to support the device at full load.
If the device is assembled on wheels (kit sold separately), it can-
not be levelled. Therefore the surface must be perfectly horizon-
tal, flat and completely smooth.
Protective lm removal
Fig. 5 If the machine is intact, remove the protective film slowly.
Any glue residue can be removed with a proper sol-
vent. Do not use tools or abrasive or strong detergents
that might ruin the surfaces.
The removed protective films are potentially danger-
ous for children and animals. DO NOT LEAVE THEM UN
ATTENDED IN THE INSTALLATION AREA AND CORRECT
LY DISPOSE OF THEM IN ACCORDANCE WITH LOCAL
STANDARDS.
Positioning
The machines must be positioned on the ground only, on floors:
- that are not sensitive to heat or flammables;
- perfectly levelled;
- with a regular surface and completely smooth;
- that can support the device at full load.
Fig. 6 Keep the illustrated minimum clearances around the de-
vice: this will facilitate connections to utilities and maintenance.
Fig. 7 Always check for perfect levelling: if this is not the case,
rotate the feet until achieved.
DO NOT INSTALL THE DEVICE:
-NEAR OTHER MACHINES THAT REACH HIGH TEM
PERATURES E.G. OVENS OR FRYERS;
-NEAR WALLS OR FURNITURE THAT IS EITHER FLAM
MABLE OR SENSITIVE TO HEAT.
Only use the manufacturer’s wheel kit to make the de-
vice movable. For assembly, if necessary, read the in-
structions supplied with the kit.
Spacer installation
The devices require ventilation at the back, where the vents and
refrigerating unit are found.
Therefore, do not place them against the wall but keep them ap-
proximately 5 cm away.
Fig. 8 In order to prevent accidental movements from shifting
the device too close to the wall, install the provided spacers on
the back of the device (especially if the device is assembled on
wheels). Use supplied spacers and screws only.

Product transport, handling
Warning markings are printed on the packaging. They indicate
the limitations that must be observed to ensure safe device load-
ing, unloading and transport.
Fig. 1 Device transport and handling must be done exclusively
as follows:
-keep the packaging in the vertical position, as per the indications
printed on it (this precaution is necessary to prevent the oil con-
tained in the compressor from circulating, which may damage
the valves and cause problems when starting the motor);
-use suitable handling means. Do not handle the goods by hand.
If hoisting systems are used, such as forklifts or pallet jacks, the
weight must be carefully balanced.
The packaging usually consists in polystyrene and stretch film on
a wooden pallet, which is secured to the bottom of the device for
safer transport and handling.
The manufacturer cannot be held liable for problems due to
transport in conditions other than those previously specified.

tions), uncovered liquids, live animals, various
objects or corrosive products in the equipment.
-Package or otherwise protect foods especially if
they contain aromas or spices.
-Arrange foodstuffs inside the equipment in such
a way as not to limit air circulation, avoiding
placing paper, cardboard, cutting boards, etc.,
that can hinder the flow of air on the racks.
-Avoid frequent and prolonged door opening as
much as possible.
-If the door was opened and closed again, wait a
few seconds before re-opening it.
-Gradually arrange the food starting from the
bottom up; vice versa, remove the food start-
ing from top to bottom. The maximum load
(evenly distributed) per tray or grill is equal to
20 kg (GN 1/1) or 35 kg (GN 2/1).

Risks associated with equipment
use
•RISKS DUE TO MOVEMENTS ON WHEELS: if the
equipment is installed on wheels, take care dur-
ing movements not to suddenly push the equip-
ment, thus preventing it from overturning and
being damaged. Also look out for any roughness
on the sliding surface. Equipment with wheels
cannot be levelled, therefore make sure the
support surface is perfectly horizontal and flat.
Always lock the wheels with the specific stops.
•RISKS DUE TO MOBILE ELEMENTS: the only mo-
bile element is the fan, which however does not
constitute a risk since it is protected by a protec-
tion grate secured with screws.
•RISKS DUE TO LOW/HIGH TEMPERATURES: stick-
ers marked “TEMPERATURE HAZARD” have been
affixed near areas with low/high temperature
risks.
•RISKS DUE TO ELECTRICITY: risks of electrical na-
ture have been resolved by designing electrical
systems as per regulation CEI EN 60335-1. Spe-
cific stickers marked “high voltage” identify areas
with electrical hazards.

How to use the needle probe
Fig. 12 The needle probe, during chilling, reads the tempera-
ture at the food “core”: when it reaches the value set by the user or
default value, it means the food is chilled ( Chilling function). The
needle probe is fully inserted in the food to be chilled: make sure
its tip reaches the food “core”, meaning the most internal point,
without exiting.
Be careful not to insert it in very fatty points and near bones.
In case of very thin food products, insert the probe parallel to the
support surface.
Always keep the probe clean and sanitised.
HANDLE THE PROBE WITH CARE INSOFAR AS IT IS
VERY SHARP.
+
The probe can be heated to facilitate removal from frozen
foods, see page 39.
Drawings on page 30
What does a blast chiller do?
A blast chiller is a device that quickly lowers the temperature of
the introduced food, whether fresh or cooked.
Fresh or just cooked food has the best sensory qualities and fla-
vour; however, if not eaten immediately, it loses its initial qualita-
tive properties and is subject to the proliferation of micro-organ-
isms, which are potentially harmfuly to humans.
Positive Chilling is used when food is not eaten within two
hours of its preparation, reducing the product temperature to
+3°C at the core within 90 minutes. Subsequently, the prod-
uct must be stored in a refrigerator at a temperature between
0/+3°C where it can be kept for up to 5 days.
Negative Chilling is used to keep all the sensory properties of
the food intact. The chiller reduces the product temperature un-
til reaching -18° C at its core. Subsequently, the product must be
stored in a freezer at a constant temperature of -20 degrees and
can even be eaten after 3/18 months, according to the product,
provided the cold chain regulations are met.
Storage is the next step in the blast chilling cycle, in which the
food product is maintained at a certain temperature in order to
preserve its cooling or freezing.
It is divided into:
Positive storage, in the case of cooling;
Negative storage, in the case of freezing.
Normal refrigerators and freezers, unlike a blast chiller, are unable
to rapidly lower the initial temperature of the product, which is
therefore damaged in terms of its sensory properties and flavour.
Correctly loading the equipment
Food should be placed in a single layer in containers:
- that are uncovered;
- that are food-safe;
- that are resistant to the temperatures reached by chilling;
- that have low edges (maximum 4.5 cm).
Containers should be evenly placed inside the cell.
Correct container placement will allow free air circulation in the
cell: avoid obstructing the air vents and overloading the equip-
ment beyond the admissible limits.
Achieving better results and working in
safe conditions
-Fig. 11 Keep the motor compartment air vents free of objects
and remove dust;
-periodically clean and replace the filter behind the motor com-
partment air vents:
+
For further information on how to remove the lter, see chap-
ter Vent cleaning on page 47.
-arrange food to be chilled or cooked as explained in the previ-
ous chapter;
- accurately close the doors during each work cycle;
- always keep the defrost water drain hole free;
- avoid opening doors during positive/negative chilling;

Switch on
When the display switches on it performs a lamp-test (flashing of
all segments and dots for 5 seconds).
When switched on for the first time, the display is in stand-by mode
(three horizontal dashes“---”are shown on the display, one for each
digit). The next time it is switched on, or when the power supply
is restored, the blast chiller status varies depending on its status
befo re the power supply failure.
If there is no program running, activate standby mode by press-
ing and holding SEL for 4 seconds.
Important information
The display shows programs for managing the following blast
chiller functions:
positive blast chilling or cooling (automatic or manual),
negative blast chilling or freezing (automatic or manual)
+
For automatic programs, the reference value is the tem-
perature detected by the needle probe.
For manual programs, the reference value is the time.
Both the automatic program and the manual program include
a blast chilling cycle, automatically followed by a storage phase,
which is positive or negative depending on the cycle chosen.
At the end of the blast chilling cycle, when the storage phase
starts automatically, a buzzer sounds intermittently (this can be
modified by the user under parameter P 0).
To silence the buzzer in advance, press the DOWN key.
During the execution of a program:
-the LED L2 is off if a positive blast chilling cycle was selected,
or is on if a negative blast chilling cycle was selected;
-the L3 LED is on during the blast chilling cycle and flashing
during the storage phase;
-pressing the UP key determines the display of the temperature
measured by the cell probe for a duration of 5 seconds;
-pressing and holding the SET key determines, until the key is
released, the display of the time elapsed since the start of the
blast chilling cycle if the blast chilling cycle is still in progress,
the duration of the previous blast chilling cycle if the storage
phase is in progress.
At the end of a program, before starting the next program, the
display shows the data relative to the last program run.
Automatic program
To select and start an automatic program (Fig. 8 on page 18), pro-
ceed as described below:
-Press the SEL key until the display shows the positive blast
chilling cycle (default +3°C - P13 parameter) or negative
blast chilling cycle (default -18 °C - P14 parameter).
-
+
The repeated pressing of the SEL key causes the display
to alternately flash between the value set for the posi-
tive blast chilling cycle and the value set for the nega-
tive blast chilling cycle.
-Wait 5 seconds or press the SET key to confirm (the tempera-
ture display becomes fixed).
-Press the SET key to start the program: during the execution
of an automatic program the display shows the temperature
measured by the needle probe.
