4.4 Turning on the refrigeration unit

Press the button of the driver's cabin control to turn on the refrigeration unit.
If diesel operation is underway, engine startup is preceded by an acoustic signal.
A maximum of 5 startup attempts are possible after which, if the engine does not
start, an alarm is signaled.
The diesel engine always starts at maximum speed for a few seconds and then
decelerates to minimum speed, remaining in this condition for a time which is
determined by the engine's temperature.
When this phase has been concluded, the engine's RPM may be varied by
pressing the key ( f i g . 2 ).
If the refrigeration unit is to be used with the electric motor, first press the but-
ton to stop the diesel engine.
Then connect the provided plug to the mains making sure that the voltage of the
mains is equal to that reported on the refrigerator's data plate.
The driver's cabin control is therefore automatically prepared for electric opera-
tion and the refrigerator unit may be turned on by pressing the button. In this
case as well, startup of the electric motor will be preceded by an acoustic signal
lasting a few seconds.
