Installing a pump in a vacuum system
➨ If dangerous or polluting fluids could be released at
the outlet, install an appropriate system to catch and
dispose of those fluids.
☞
Connect a gas-tight exhaust line at the pump outlet if
necessary. Always vent exhaust gases appropriately
(e.g., into a fume hood).
☞ Never block the gas outlet. The exhaust line must al-
ways be free of obstructions (no back pressure) to en-
sure an unimpeded discharge of gas. The cross-sec-
tion of the outlet tubing must be at least the size of the
pump’s exhaust connection.
☞ Maximum permissible pressure at the pressure trans-
ducer: 21.8 psi (1.5 bar) absolute.
☞ Attention : At pressures above approximately 810 Torr
(1080 mbar) the pressure reading becomes incor-
rect. The display will flash and a warning message will
be displayed. Release pressure immediately! Risk of
bursting!
☞ Particles and dust must not be aspirated. If necessary,
you must install appropriate filters. You must ensure
their suitability concerning gas flow, chemical resis -
tance and resistance to clogging prior to use.
☞ Make sure ventilation is adequate, especially if the pump
is installed in an enclosure, or if the ambient temperature
is elevated. Provide external ventilation, if necessary.
