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: 21.8 psi (1.5 bar) ab-
solute.
+
Attention: At pressures above approximately 795 Torr
(1060 mbar) the pressure reading becomes incorrect
due to saturation of the pressure transducer. The dis-
play will flash. 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.
Use and operation
When switching on the controller CVC 3000 for the very first time, a menu
to select the language of the controller menu is displayed. Select the de-
sired language (e.g., ”English”) by turning the selection knob and press
to confirm. Then select the pressure unit (”mbar”, ”Torr” or ”hPa”) in the
same way.
It is possible to access the language selection menu at any time
by switching on the controller while keeping the selection knob
pressed.
