HOLD PHASE: To select Hsymbol pushing the .
Cycles are pre-set with the following values:
•Cy1: for fast chilling and conservation of foods (hard +soft chill).
•Cy2: for chilling and fast freezing of foods (hard +soft + freezing
cycle).
•Cy3: for direct fast freezing (only fast freezing cycle)
•Cy4: for fast freezing avoiding ice skin (hard chill + freezing
cycle)
•HLd: hold mode function

Example of Blast Chiller Cycle
The following drawing explains how a Blast Chiller cycle can be done.

11
1. First phase: Hard Chill
It is usually used to blast chill food just cooked.
It is normally used to fast chill hot foods. (e.g., from 80°C / 170°F
to 20°C / 70°F). During “Hard Chill”, both compressor and fan are
always on until the rS1 temperature is reached. At this point
compressor is turned on end off to keep the temperature of the
room at the rS1 value. “Hard Chill” ends when the temperature
measured by the insert probes reach the iS1 value.
2. Second phase: Soft Chill
The Soft Chill starts when the Hard Chill ends. It is used to
prevent thin layer of ice from forming on the product. The Soft
Chill lasts until the temperature measured by the insert probes
reach the set point iS2. During Soft Chill the temperature of the
room is regulated by the ambient probe with the set point rS2.
3. Third phase: Freezing Cycle
Freezing Cycle: used to fast freeze foods. The Freezing Cycle
starts when the Soft Chill ends. During the “Freezing Cycle” both
compressor and fan are always on until the rS3 temperature is
reached. At this point compressor and fans are turned on end off
to keep the temperature of the room at the rS3 value (normally
some degrees below iS3). Freezing Cycle ends when the
temperature measured by the insert probes reach the iS3 value.
4. End of Freezing Cycle & Start of Hold Phase (selectable)
The end of the freezing cycle is indicated by the sound of the
buzzer (Option). The alarm automatically stops after the “but”
time or by pressing any keys.
Once the freezing cycle is complete, the instrument
automatically starts the hold phase at the temperature set in
parameter HdS. If Cap = No, the hold phase is not carried out.
NOTE:
1. with dbH = yES a defrost is done before the holding phase.
2. If the end cycle temperature iS3 is not reached in the
maximum time Pd1+Pd2+Pd3(Option) the instrument keep
on working, but the alarm message “OCF” is given.

Cleaning and Maintenance
To make sure that the freezer is in optimum condition, the interior and
accessories must be cleaned regularly.
•Before performing cleaning activity, switch off the appliance and
unplug the power cord.
•Do not use abrasive cleaners.
•Clean the interior and accessories using cloth and lukewarm water.
After that, clean with clean water and dry completely.
•Dust can accumulate on the condenser and cause performance
drop. Clean the freezer condenser at least once a year using soft
brush or vacuum cleaner.
•After everything is dried completely, install the accessories and
freezer to the initial position.
•Clean the condenser & evaporator periodically from debris and dust
to ensure maximum performance
Check the following before contacting our Service Center in the event
of malfunction
