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 dis-
pose 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.
+
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.
• Reduce the transmission of vibration. Prevent mechan-
ical load due to rigid pipelines. Insert elastic hoses or
flexible elements as couplings between the pump and
rigid pipes.
Note: Flexible elements will compress or flatten when
evacuated if not designed for use under vacuum.
• Hose connections at the pump inlet must always be
gas tight.
• A power failure may cause accidental ventilation of the
pump, especially if the gas ballast valve is open. If this
constitutes a potential source of danger, take appropri-
ate safety measures.
• Check the power source and the pump’s rating plate
to be sure that the power source and the equipment
match in voltage, phase, and frequency.
The ON/OFF switch is at the left side of the pumping
unit.
After switching off the pump, wait minimum 60 sec. before
switching on again.
Keep a distance of minimum 8 in (20 cm) between fan/
pumping unit and adjacent equipment or casework.
Use connecting hoses with large diameter and keep them
as short as possible to avoid flow losses. Locate the pump
as closely as possible to the application.
Always install outlet tubing descending from the pump to
avoid backflow of condensate towards the pump.
Use a suitable valve to isolate the pump from the vacuum
application. This is to allow the pump to warm up before
pumping condensable vapors and to clean the pump after
use before it is switched off.
