Important Safety Information
0.1 Mechanical Hazards
1
Avoid exposing any part of the human body to the vacuum.
2
Never put fingers or foreign matter into the pump‘s inlet or the clear-
ance of fan blades. If done, it can cause injury.
3
Make sure that the gas flow from the exhaust port is not blocked or
restricted in any way.

Pumps with single-phase motors have an internal thermal protector.
These motors restart without warning after the protector trips back.
0.2 Electrical Hazards
1
Wiring must be done by a qualified electrician. Otherwise there is the
risk of suffering an electric shock.
2
Prevent short-circuits with a ground fault circuit interruptor (GFCI) of
