PRE-COOLING START-UP
Every operating cycle can be preceded by pre-cooling.
Operate as indicated to start pre-cooling:
1. Make sure the device is in the "ON" status.
2. Make sure that the keyboard is not locked and that no
procedure is in progress.
3. Press and release the key (1) and then press and
release the START/STOP key (2).
4. The cycle can be stopped at any time by pressing and releasing the START/STOP key.
Parameter r120 establishes the work set-point during pre-cooling.
When the cabinet temperature reaches that established with parameter r12, pre-cooling continues, and
the buzzer is activated for 2s to indicate that the pre-cooling cycle has been completed.
SWITCHING ON UV LIGHT FOR STERILIZATION CYCLE (if available)
Operate as follows:
1. Make sure that parameter u11 is set at 2.
2. Make sure the device is in the "ON" status and that
the door is closed, the door switch is not active.
