It is recommended to carefully read the instructions and warnings contained in this manual before
using the appliance. The informat io n c ontained in the manual is fundamental for the safety of use and for
machine maintenance.
Keep this manual carefull y 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 pow er supply upst ream from the applianc e (requested for appliances supplied
without plug to connect to the fi xed 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 r espec t t hose r egarding 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 sw it ch-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 per formance and safety.
Never stretch the power cabl e.
In order to guarantee hy giene and pr ot ect t he food stuffs from contaminatio n, t he e lements 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,
3
avoiding inflammable products or those that contain substa nces 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 inter nal and external par ts of the appliance.
3.RECOMMENDATIONS FOR USE
Prolonged Inact ivity
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 oi l onto t he 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 con denser clean.
Do not insert foodstuffs t hat ar e we ll abov e the t e m perature 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 t o ac ceptable values.
Check the planarity of the app lia nce r est surface.
Do not stack the materials to be preserved in contact with the internal walls .so blocking the
circulation of air , which gu arantees un iformity of the interna l temperatur e of the refrigerate d compar tment .
There must be a suffici ent sp ace b etw een the ba sin s and t ray s used in ord er to guarant ee a sufficient
flow of cold air on the entire pr oduct. Therefore avoid the following positions of trays and/or basins stated
below.
Never obstruct the inlet of t he evaporator fans.
Products that are more difficult to chill because of their composition and size shoul d be placed in the
centre.
Limit the number of times and the duration of time the doors are opened.
Blast chilling data r efer to stand ard product s ( low fat cont ent )with a th icknes s below 5 0 mm: ther efore
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 exp iry d at e. When the pr oduct has been bl ast ch ille d it must be pr es erv ed at a c onstant
+2
temperature of
-20
。
，while if it has been shock frozen it must be preserv ed at a const ant t emperat ure of
The chiller should be used for st or age for short periods only.
T o preve nt bacterial co ntaminati on or contami nation of any other bi ological na ture,
the needle probe must be disinfected af ter use.
To extract the product that has undergone blast chilling or shock freezing ,always wear gloves to
protect the hands ,as “bur ns” m ay 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 chill i ng pr ocess 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 te mperatur e of shoc k freez ing .For shoc k freezing t o be succes sful and fast, food
should be in small pieces, especiall y 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 pr oduct.
