Ensure proper grounding of the pump. Otherwise there exists the risk of
suffering an electric shock or igniting a fire.
Never put fingers or foreign matter into the pump's inlet or the clearance
of fan blades. If done, it can cause injury.
Install in an area which is not exposed to moisture such as rain or steam.
Exposure to moisture can cause eIectric shock.
Never alter the equipment. Modifications can damage the equipment or
shorten its service life.
Be sure to check wiring diagram before connecting a power supply.
Failure to do so can result in damage.
Pumps with single-phase motors have an internal thermal protector.
These motors restart without warning after the protector trips back.
Be sure to switch off the electric power before maintenance or inspection.
Failure to do so can result in electric shock or bodily injury by rotating
objects.
Use at ambient temperatures of 5 - 40 °C (during operation). Operating
outside of this range can cause damage or shorten service life.

Conduct periodic maintenance and inspections. Failure to do so can
cause damage or reduced service life.
Do the maintenance after the pump has fully cooled down. Performing
maintenance on a hot pump can cause burns.
Be sure to close the isolation valve between pump and vacuum system
(chamber) during startup and shutdown. If this valve is open, debris atta-
ched to the inside of pump can be drawn back into the vacuum chamber.
