Instructions for Use
Use
When first installed or after a long period of non-use, in order to reach maximum
vacuum performance, the pump must be left running for about an hour with the
inlet sealed assuming there is no leakage.
There are no special instructions for starting the pump; it need only be switched on
using the ON/OFF switch.
The pump is designed for operation with neutral or noncorrosive fluids.
WARNING
It is absolutely forbidden to use it with potentially explosive or inflammable
substances.
