page 23 of 100 • The equipment is designated for a low degree of mechanical stress and has to be installed in a way so that it cannot be damaged from outside. Pumping units have to be installed so that they are protected against shocks from the outside and against glass splinters in the event of breakage (implosion).

Inlet: Hose nozzle for tubing I.D. 3/8” (10 mm) (ME 1C, MZ 1C) or hose nozzle for tubing I.D. 1/4” / 3/8” (6/10 mm) (ME 1). Connect the vacuum line (e.g.,vacuum hose inlet I.D. 3/8” (DN 10 mm) at the inlet of the pump.
Page 31
page 31 of 100 • Reduce the transmission of vibration. Pre- vent mechanical 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.
Check the silencer regularly for permeability! In case, install a hose nozzle instead (*, see “Accessories / Spare parts”, pg. 39). Connecting an exhaust line at the pump outlet (ME 1): Unscrew the silencer and install a hose nozzle DN 10/6 mm (thread G1/8”).
page 33 of 100 ✘ ✘ Always install outlet tubing descending from the pump or provide other measures to avoid backflow of condensate towards the pump. ✔ ✔ Electrical connection Plug in the power cord. O ➨ I • 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.
page 34 of 100 Changing the selection at the voltage se- lection switch: • Change the selection at the voltage se- lection switch only, if the pump is un- plugged from the power source. 1. Disconnect the electrical power cord. 2.
page 35 of 100 During operation ➨ Vent and dispose of potentially dangerous gases or vapors at the outlet of the pump appropriately. ☞ Due to the high compression ratio, the pump might generate overpressure at the outlet. Check pressure compatibility with system components (e.g., exhaust tubing or exhaust valve) at the outlet.
Page 36
page 36 of 100 • If the pump is installed at an altitude of more max. 6500 ft than 6500 ft (2000 m) above mean sea lev- (2000 m) el, check compatibility with applicable safety requirements, and adopt suitable measures. There is a risk of the motor overheating due to insufficient cooling.

page 38 of 100 Important notes regarding the use of gas ballast Gas ballast is a continuous purge to keep the pump’s in- terior as clean as possible and to reduce the possibility of condensation inside the pump. ➨ Air and pumped media might react inside the pump or at the outlet of the pump and form hazardous or explo- sive mixtures, when you use air rather than inert gas for the gas ballast.
The resultant back pressure can lead to damage of pump bearings, diaphragms, and valves. Under those conditions, a silencer must not be used.

Only if the pump achieves its specified ultimate vacuum, the pump’s leak rate is low enough to ensure that no explosive atmospheres will occur in the inte- rior of the equipment.
page 87 of 100 If the pump does not achieve the ultimate vacuum: - Whenever the diaphragms and valves have been replaced, a break-in period of several hours is required before the pump achieves its ulti- mate vacuum. - In case of an unusual noise, switch off pump immediately and check clamping disc positions.
