2. SAFETY
It is recommended to carefully read the instructions and warnings contained in this manual before
using the appliance. The information contained in the manual is fundamental for the safety of use and for
machine maintenance.
Keep this manual carefully so that it can be Consulted when necessary.
The electric plant has been designed in compliance with the IEC EN 60335-2-89 and EN 60335-1
standard.
Specific adhesives highlight the presence of mains voltage in the proximity of areas(however
protected)with risks of an electrical nature.
Before the connection, ensure the presence of an omni polar switch with minimum contacts opening
equal to 3 mm in the mains power supply upstream from the appliance (requested for appliances supplied
without plug to connect to the fixed plant).
In the design and construction phase, the manufacturer has paid particular attention to the aspects that
can cause risks to safety and health of persons that interact with the appliance.
Carefully read the instructions stated in the manual supplied and those applied directly to the machine,
and particularly respect those regarding Safety.
Don’t tamper or eliminate the installed safety devices. Failure to comply with this requisite can Lead to
serious risks for personal health and safety.
It is recommended to simulate some test manoeuvers in order to identify the controls, in particular those
relative to switch-on and switch-off and their main functions.
The appliance is only destined for the use for which it has been designed; any other use must be
considered improper.
The manufacturer declines all liability for any damage to objects or injury to persons owing to
improper or incorrect use.
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 food stuffs 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,

4
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.
3.RECOMMENDATIONS FOR USE
Prolonged Inactivity
If the appliance remains inactive for a long period, proceed as follows
1. Use the automatic isolating switch to deactivate connection to the main electrical line.
2. Clean the appliance and surrounding areas thoroughly.
3. Spread a thin layer of cooking oil onto the stainless steel surfaces
4. Carry out all maintenance operations
5. Leave the doors ajar to prevent the formation of mould and /or unpleasant odour.
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.
Do not insert foodstuffs that are well above the temperature of 65℃. 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.
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.
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.

5
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
℃
，while if it has been shock frozen it must be preserved at a constant temperature of
-20
℃
。
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 form the cold.
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℃。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℃，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.
