Operation
2.4 Start-up
Each time before starting up check the oil
level.
For pumps with 3-phase motors, check the direction of
rotation before starting the pump for the first time and
after each change in the electrical connection (see
Section 2.3.2).
On initial start-up, after prolonged idle periods or after an
oil change, the specified ultimate pressure cannot be
attained until the oil is degassed.
This can be done by running the pump for approx. 30
min. with the intake line closed and the gas ballast valve
(7/5) open.
Before starting the pump ensure that the
pump and the fitted accessories meet the
requirements of your application and that
safe operation can be guaranteed.
Avoid exposure of any part of the body to
the vacuum. There is the danger of injury.
Never operate the pump with an open
intake port. Vacuum connections as well as
oil-fill and oil-drain openings must never be
opened during operation.
The safety regulations which apply to the
application in each case must be observed.
This applies to installation, operation and
during maintenance (service) as well as
waste disposal and transportation.
The standard pump is not suited for
pumping of hazardous gases or vapours.
Our technical sales department is available for further
advice in these matters.
