6.2 BLAST CHILLING/BLAST FREEZING
See points 7777.0 .0 .0 .0 and 8888.0 .0 .0 .0 for details.
6.3 OPENING THE DOOR WHILE A CYCLE IS RUNNING
If the door is opened while a blast chilling/blast freezing cycle is running, the "]]]]----[[[[" code will flash up
intermittently on display DY2
DY2 DY2 DY2 and, at the same time, a buzzer will sound. The compressor and fans inside stop
and only restart once the door is closed.
The blast chilling/blast freezing cycle cannot be started with the door open. If the door stays The blast chilling/blast freezing cycle cannot be started with the door open. If the door stays The blast chilling/blast freezing cycle cannot be started with the door open. If the door stays The blast chilling/blast freezing cycle cannot be started with the door open. If the door stays

When button
is pressed to stop a blast chilling, blast freezing or holding cycle manually, the compressor
keeps working for 5 5 5 5 more seconds.
6.5 TEMPERATURE SENSOR AND NEEDLE PROBE READINGS
While a temperature-based cycle is running, DY1 DY1 DY1 DY1 indicates the value the value the value the value measured by the needle probe. You can
view compartment sensor temperature by pressing the button relating to the cycle selected: , or .
The value is put up on DY1 DY1 DY1 DY1 for 5 5 5 5 seconds.
While a time-based cycle is running, DY1 DY1 DY1 DY1 indicates the value the value the value the value measured by the compartment sensor. You can
view needle probe temperature by pressing button . The value is put up on DY1 DY1 DY1 DY1 for 5 5 5 5 seconds.
6.6 HEATED NEEDLE PROBE (Optional extra)
The heated needle probe (optional extra) has a device that heats its tip, making it easier to pull out of frozen
products. Holding button
down for 5555 seconds at the end of a blast freezing cycle turns on heating so that
the probe can be easily removed from the frozen product. Heating only comes on if the door is open.
6.7 AUTOMATIC DEFROSTING
During operation, frost forms on the surface of the evaporator: this is normal but it reduces evaporator
efficiency. The purpose of defrosting is to restore full efficiency. Defrosting is performed automatically:
