Continuous Blast (USA Models Option Only)
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. Thus, if it is not 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 ashing.
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 indicate
the following:
A manual defrost can be initiated by pressing and
holding both and .
During the defrost cycle all fans will stop running.
When the defrost cycle is nished 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 aect the products stored.
After every defrost there is a short period - about
5 minutes during which a blast cycle cannot be
programmed. This short interval is to allow defrost
water to drain away from the evaporator. At the end
of each cycle, a defrost will automatically clear any
ice from the evaporator ready for the next cycle.
Alarms
When a fault or adverse operational condition
arises, an audible and visual alarm will be initiated:
The alarm will sound intermittently. Press to
mute the alarm, the alarm will retrigger if the fault
causing the alarm has not been addressed. The
alarm mode will still be displayed.
More information on the alarm can be displayed
during normal operation by accessing the diagnostic
menu by pressing and holding for 3 seconds.
When a probe is at fault then the windows will
display as follows:
T1 - air probe T4 - Food Probe 1
T2 - evaporator T5 - Food Probe 2
T3 - auxiliary probe
(not applicable)
T6 - Food Probe 3
Alarm codes that are displayed are:
E1 - HP/LP fault (not applicable)
E2 - Over temperature
E3 - Mains failure longer than 3 minutes
Hi - High temperature
Lo - Low temperature
or - Probe over range failure
Alarms during Blast Cycles
If the blast chill cycle has been terminated as a result
causing an alarm, a defrost cycle will automatically
be initiated. However, if an alarm occurs such as
evaporator probe (T2) fault then the blast chill cycle
will continue.
