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.

17. How A Cycle Is Done
1. Every programmable cycle Cy1, Cy2, Cy3 or Cy 4 can be divided into up to 3 phases usua l ly called:
• hard chill
22
• soft chill
• freezing cycle
2. For each phase there are 3 par ameters.
iS1, (iS 2, iS 3): Set point related to the insert pr obes that stops the current phase.
rS1, (rS2, rS3): set point of the room temperature for each phase.
Pd1, (Pd2, Pd3): the maximum durat ion time for eac h phase.
Hds : set point of the hold phase at the end of the whol e cycle.
There are also 3 parameters:
first one concerning the cycle way of doing the cy cle: by t emperature or by t ime, t he other two ar e related
to the defrost. These are dbC = defrost before cycl e, dbH = defrost before holding (at the end of the
cycle).
17.1 CONFIGURABLE CYCLE PARAMETERS
cyS Cycle setting: tEP = by temperature. the cycle is done according to the rEM parameter; tiM: timed
cycle, based on the Pd1, Pd2, Pd3 parameters.
dbc (yes/no) Defro st before the cycle
iS1 (-50÷50°C;1°C/1°F) Inser t Probe Set point: when the temperature m easured by the three insert
probes reaches this valu e the first phase is ended.
rS1(-50÷50°C; 1°C/1°F) R oom probe S et point for t he first phase: it prev ents te mperatur e from rea ching a
too low value during the hard cycle.
Pd1 (OFF÷4.0h;10 min)Maximum time for first phase
iS2 (-50÷50°C; 1°C/1°F) Insert probe set point when the temperature measured by t he t hr ee insert
probes reaches this valu e the second phase is ended.
rS2 (-50÷50°C; 1°C/1°F) Room probe Set point for the second phase: it prevents temperature from
reaching a too low value dur ing the second phase.
Pd2 OFF÷4.0h; res. 10 min Maximum time for second phase.
iS3 (-50÷50°C; 1°C/1°F) Insert Probe Set point to stop the third (and last ) phase: when the temperature
measured by the three insert pr obes r eaches this value the third phase is ended.
rS3 (-50÷50°C; 1°C/1°F) Room probe Set point for the third (and last) phas e: it prevents temperature
from reaching a too low value during the third (and last ) phas e.
Pd3 (OFF÷4.0h; 10 min) Maximum time for the third phase.
dbH (yes / no) def rost before the hold phase
HdS (-50÷50 - OFF; 1 °C / 1°F) Set point of the holding phase. With “OFF” the hold phase is dis abled.
IMPORTA NT NO TE: If the duration time of a ph as e is set at the OFF value, the corresponding phase is
disabled. E.g. If Pd3= 0FF the third phas e of the cycle is not active.
17.2 HOW TO USE THE INSERT PROBES
By means the insert probe , t he interna l temperature of products can be checked. This measur e is us ed t o
end the various phase of the cycle. A special internal function detect if the inset pr obe is not used, in this
case the cycle is made by time
17.3 EXAMPLE OF A BLAST CHILLER CYCLE.
The following drawing explains how a Blast Chiller cycle can be done.
23
17.3.1 First phase: “Hard chill”.
It is normally used to fast chill h ot foods. E.g. from 80°C / 170°F to 20°C / 70°F
During “Hard Chill”, both compressor and fan are always on unt il the rS1 temperature is r eached. At
this point compressor i s tu rned o n end off s o as to k eep the t em peratur e o f th e roo m at t he rS1 value.
“Hard Chill” ends when th e t emp er ature measured by the 3 insert probes reach the iS1 value.
17.3.2 Second phase: “Soft chill”.
The Soft Chill starts when the Hard Chill ends. I t is used t o pr event thin layer of ice from forming on
the product. The Soft Chill lasts unti l the temperature measured by the 3 insert probes reach t he set
point iS2 (usually 4 or 5°C).
During Soft Chill the temp erature of the ro om is regu lated by t he ambient prob e with the set point rS2
(normally at 0 or 1 °C / 32 or 34°F). When the box temperature r eaches the rS2 value compressor is
turned on end off so as to keep the te mp er at ur e of the box at this value.
17.3.3 Third phase: “Fre ezi ng cycle”.
Freezing Cycle: used to fast freeze foods.
The Freezing Cycle starts when the Soft Chill ends. During the “Freezing Cycle” bot h compressor
and fan are always on until the rS3 t emperature is reached. At t his point compressor and fans ar e
turned on end o ff so as t o keep th e temp erature of t he roo m at the rS3 value (normally some degrees
below iS3).
Freezing Cycle ends when the temperature measured by the 3 insert probes reach the iS3 value
(normally -18°C / 0°F), in any case it ends when the maximum time Pd1 + Pd2 + Pd3 has expired.
17.3.4 End of the Bl as t Chill cycle and starting of the Hold Mode.
When one of the three inser t pr obes r eaches the iS3 value the values End followed by t he i1 P or i2P
or i3P are shown on the display.
Cycle ends when all the probes h av e reache d the iS 3 value. A signa l is gener at ed: buz z er and alarm
relay is turned ON, the display s how s t he message “End” alternating with the room temperature.
The alarm automatically stops after the “but” time or by pressing any keys.
At the end of the cycle the controller can start the “Hold mode” keeping the room temper at ur e at t he
value set in HdS parameter.
If HdS = OFF, the machine is turned OFF.
NOTE1: with dbH = yES a defrost is done before the holding phase.
NOTE2: If the end cycle temperature iS3 is not reached in the maximum time Pd1+Pd2+Pd3 the
24
instrument keep on working, but the alarm mes sage “OCF” is given.
