The vacuum pump is also a compressor:
incorrect use may be dangerous.
Study the user manual before starting up the
pump. External inputs (contact or voltage) can
be used to stop the turbomolecular pump in case of
roughing pump power failure (see External fault on B 91).
WARNING
The access to the rotor of a turbomolecular
pump with an unconnected intake is dangerous.
Similarly, if the pump is not switched on, it may
be driven by another pump in operation (risk of
injury).
WARNING
• Make sure that the parts or chambers connected to
the inlet of our pumps withstand a negative pressure
of 1 bar in relation to the atmospheric pressure.
• The leaktightness of the products is guaranteed when
they leave the factory for normal operating conditions.
It is the user's responsibility to maintain the level of
leaktightness particularly when pumping dangerous gases.
For process pumps:
If loss of purge flow creates a significant risk,
then the external monitoring of the purge flow
and the response to loss of purge flow must be
provided by the process equipment and interlocked if
necessary.
If pyrophoric materials above the LEL are sent to the
pump then nitrogen should be supplied at a rate to
ensure that concentration is diluted to be below the LEL,
in addition an interlock should be provided to ensure that
gas flow to the pump is stopped when nitrogen is lost.
WARNING
• The performance and the operational safety of this
product are guaranteed provided that it is used in normal
operating conditions.
