probe reaches temperature.
- Mains failure longer than 3 minutes.
The LED's beneath the right-hand display window
indicate whether or not each enabled food probe has
achieved the target temperature (temperature setpoint).
If the LED is illuminated, the food probe relevant to that
LED is yet to reach the target temperature. Thus, if it is
not illuminated, the food probe relevant to that LED is yet
to reach the target temperature.
illuminated, that food probe has achieved the target
temperature. The LED will illuminate once more when
the temperature relevant to that probe reaches 10°C
(10°F) above the target temperature (for example:
inserted into hot food).
At the end of a cycle, an audible alarm will sound for 10
seconds with the left window displaying the time and in
the right window the LED's will start flashing.
DEFROST
A defrost cycle is automatically instigated at the end of
each blast chill cycle to clear any ice from the
evaporator ready for the next cycle. During storage
mode a defrost will be performed automatically at the
factory preset interval of 6 hours. If a blast cycle is
cancelled the machine will automatically initiate a defrost.
During a defrost the display windows will indicated the

During the defrost cycle all fans will stop running. When
the defrost cycle is finished the compressor will run for
approximately 60 seconds before the fans cut in. It is
safe to leave products in the cabinet during the defrost
cycle - the air temperature rises slightly but will not affect
the products stored.
After every defrost there is a short period - about 5
minutes during which a blast cycle cannot be pro-
grammed. This short interval is to allow defrost water to
drain away from the evaporator. At the end of each cyle,
a defrost will automatically clear any ice from the evapo-
rator ready for the next cycle.
ALARMS
When a fault or adverse operational condition arises, an
audible and visual alarm will be initiated:
