7.5 – CONTROL PROCEDURES
The entire appliance is controlled by an electronic circuit board.
When the machine is powered the appliance display illuminates fully for a “lamp-test” lasting a few seconds, at the end of
which it returns to the condition it was in before being switched off. In particular, if a cycle was in progress it will re-start
from the point at which it was interrupted.
With the circuit board OFF the display is completely off, except for the icon. Press the button to turn off the
icon on the display and go to STANDBY, which shows the chamber temperature in blue.
The various machine functions can be activated by using the controls on the panel and observing the indications on the
display.
With the circuit board in STANDBY you can go from one cycle to another simply by pressing , .
With the circuit board on STANDBY and a cycle selected you can start the cycle by pressing (START). Pressing
(STOP) once blocks the cycle in progress.
The buzzer can be silenced, whatever its cause, by pressing any button.
Whatever situation the machine is in, holding down for 3 seconds cuts OFF the circuit board.
7.6 – USE PROCEDURES
Clean the inside of the chamber before using the machine.
After installation or a prolonged idle period, it is good practice to operate the empty appliance until it reaches the set
temperature.
To achieve good output from the blast chiller it is advisable to place the food inside in such a way as to assist air
circulation: do not obstruct the fan, do not stack trays on top of each other, distribute the load neatly and do not cover the
containers with lids or cling film.
In order to avoid altering the food, it is also advisable not to overload the machine beyond the permitted load, not to use
pieces thicker than 50-70mm. and to limit door opening as much as possible.
Clean and sterilise the core probe before use. The probe must be placed in the centre of the largest joint or piece,
taking care that the point does not go right through the food to come into contact with the tray.
To improve the efficacy of the working cycle is recommended to perform a pre-cooling of the cell, by turning on
the machine at least 15 min before insert the product, both in killing and freezing.
When a temperature controlled cycle is selected the electronic circuit board checks the temperature read by the
chamber probe and core probe to assess correct insertion of the probe (AUTOMATIC probe identification). This
check lasts just over two minutes, at the end of which the cycle proceeds normally if the probe is properly
inserted. This check lasts just over 2 minutes, accordingly with established parameters, at the end of which the
cycle proceeds with a temperature controlled cycle if the probe is properly inserted. In this case the temperature
of the probe will be showed and the icon will remain turned on.
If the test has a negative result, after a minute of buzzer’s alarm, the display will show the icon and the cycle
will proceed with a time controlled cycle.
