QUICK START GUIDE

General Features

The chilling and freezing cycle is programmed according to International Food Safety Standards. There are 4 (four) types of cycle:

1. Cy1: For fast chilling and conservation of foods at positive temperature
2. Cy2: For chilling and fast freezing of foods with holding
3. Cy3: Direct fast freezing with holding
4. Cy4: Direct fast freezing without holding

See Appendix 1 about Cycle Parameters for more details

Example of Blast Chiller Cycle

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

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 arealways 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.

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.

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.

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 aximum time Pd1+Pd2+Pd3(Option) the instrument keep on working, but the alarm message “OCF” is given.

MAINTENANCE

Cleaning and Maintenance
To make sure that the freezer is in optimum condition, the interior and accessories must be cleaned regularly.

IMPORTANT!
Appliance must not be connected to the main electrical socket during cleaning! Risk of electric shock!

• 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
