The appliances are provided with a standard 2P+T-10/16A German plug for
connection to the electricity mains.
Insert the plug in a compatible power socket supplied by the mains.

5.2.3 CHECkINg THE dIrECTIoN of PuMP roTaTIoN IN 400v THrEE-PHaSE MaCHINES

Procedure:
a) Check to make sure the voltage indicated on the machine nameplate corresponds to that of your mains
supply (fig. 1).
b) Insert the plug in the socket with the machine Off.
c) Check the oil level in the pump through the glass window provided on it (fig. 2). If the level is insufficient,
follow the instructions described in the "CHANGING THE PUMP OIL" Chapter.
d) Lift the plexiglas cover after lowering the lid holder.
e) Switch the machine On by means of the main ON/OFF switch provided on the front of the machine.
f) Lower the cover to close it: the machine starts up automatically. With the pump rotating in the correct direc-
tion, the cover will remain lowered to create vacuum (or an underpressure) inside the chamber; otherwise,
the cover will rise again since air is blown in, not extracted from the chamber. In this case, switch Off the
machine immediately and have a specialist technician invert the power supply phases.
Check the direction of pump rotation every time the three-phase socket is changed!
ElECTrIC HaZard!
only specialist technicians must be allowed to invert the power supply phases.
