
Make sure that the individual components are only connected, combined and
operated according to their design and as indicated in the instructions for use.

If the equipment is brought from cold environment into a room for operation, allow
the equipment to warm up (pay attention to water condensation on cold surfaces).

Make sure ventilation is adequate if pump is installed in a housing or if ambient
temperature is elevated.
If the equipment is used in a manner not specified by the manufacturer, the protection
provided by the equipment may be impaired.
Obey all relevant safety requirements (regulations and guidelines) and adopt suitable safety
measures.

Provide a firm level platform for the equipment and check that the system to be
evacuated is mechanically stable and that all fittings are secure.
Note:
Flexible elements tend to shrink when evacuated.
Due to the high compression ratio of the pumps, pressure at the outlet port might be
generated being higher than the max. permitted pressure compatible with the mechanical
stability of the system.
Ensure that the system design does not allow the exhaust pipeline to become blocked:

Avoid overpressure of more than 0.2 bar in case inert gas is connected.

The diameter of the inlet and outlet pipeline should be at the least as large as the
diameter of the pump connection pipelines.

Adopt suitable measures in case of differences, e. g. using the equipment outdoors,
installation in altitudes of more than 1000 m above mean sea level, conductive
pollution or moisture.
WARNING:
Obey maximum permitted pressures and pressure differences, see Technical data on
page 6. Do not operate the pump with overpressure at the inlet.
WARNING:
Do not permit any uncontrolled pressurizing (e. g. make sure that the exhaust pipeline
cannot become blocked). If you have an exhaust‐isolation valve, make sure that you
cannot operate the equipment with the valve closed. Risk of bursting!
WARNING:
Pay attention to symbol “hot surfaces” on the equipment. Adopt suitable measures to
prevent any danger arising from the formation of hot surfaces or electric sparks.
