10.0 MANUAL CYCLE (MODI)
The MANUAL CYCLE mode allows you to start a probe or timed cycle setting the
desired temperature and ventilation.
While the cycle is in progress, the display will show the temperature of air inside
the cell. It is possible to view the temperature of the core probe by touching the
centre of the display where the temperature in the cell is displayed.
In the bottom left corner there is the icon next to the set ventilation
percentage. By pressing on the icon, it will be possible to change the ventilation
percentage during the current cycle.
In the top right corner there is the icon with the temperature set for this cycle
alongside. By pressing on the icon it will be possible to change the temperature of
the cycle in progress
Pressing on the icon will start a manual defrost cycle.
11.0 UTILITIES
The UTILITIES menu can be accessed scrolling down through the main screen
functions. It allows you to start a defrosting cycle, heat the core probe (optional
only MODI), export the HACCP data, update the software, back up the data and
view the alarm log.
11.1 DEFROSTING
Defrosting can be started:
-automatically during a storing phase, at predetermined time intervals.
- manually from UTILITIES>DEFROSTING.
-manually during storing by tapping the defrosting button .
When the defrosting cycle is in progress, the display shows the message
“DEFROSTING”
Tap on STOP to stop the defrost process in advance.
Note
If the appliance has remote condensing units, defrosting is done by forced air.
For a correct execution the door must remain open, as the evaporator is
defrosted by heat exchange with the surrounding ambient temperature and by
ventilation. The chamber must be empty during this phase. For this reason, in
machines connected to a remote unit, the defrosting function is activated
manually by the operator based on the frequency of use of the machine
