Install an external automatic ventilation system if necessary. If pumping hot process gases, make sure that the maximum permitted gas in- let temperature is not exceeded. - Page 13 page 13 of 67 + Do not permit any uncontrolled pressurizing. Make sure that the exhaust pipeline cannot become blocked. If there is an exhaust isolation valve, make sure that you cannot operate the equipment with the valve closed to avoid a risk of bursting! + Always provide a free and pressureless exhaust outlet to avoid damage to pump valves and risk of bursting.

page 16 of 67 + The pumps are not suitable for pumping dust. Do not pump dust. • Do not pump substances which may form deposits in- side the pump. The pumps are not suitable for pumping substances which may form deposits inside the pump. Deposits and condensate in the pump may lead to in- creased temperatures even to the point of exceeding the maximum permitted temperatures. - Page 17 page 17 of 67 failure, mechanically generated sparks, hot surfaces or static electricity may ignite these mixtures. Use inert gas for venting, if necessary. ➨ Drain appropriately or otherwise remove any potentially explosive mixtures at the outlet of the pump, or dilute them with inert gas to non-explosive concentrations.

The overall category of the equipment depends on the connected com- ponents. If the connected components do not comply with the classifi- cation of the VACUUBRAND equipment, the specified category of the VACUUBRAND equipment is no longer valid. Vacuum pumps and vacuum gauges in category 3 are intended for con- nection to equipment in which during normal operation explosive atmo- spheres caused by gases, vapors or mists normally don’t occur;... - Page 23 page 23 of 67 The pumps are marked with ”X” (according to EN 13463-1), i.e., restric- tions of the operation conditions: • 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.

Page 38: Use And Operation
page 38 of 67 Use and operation 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. - Page 39 page 39 of 67 • 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.
- Page 40 page 40 of 67 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.

Page 42: During Operation
page 42 of 67 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 gen- erate overpressure at the outlet. Check pressure com- patibility with system components (e.g., exhaust tubing or exhaust valve) at the outlet. - Page 43 page 43 of 67 ME 4R NT: • Note: There are no stops at the end of the dispensing screws’ threads! Do not completely unscrew the dis- pensing screws! Do not start the pump if the pressure difference between NOTICE inlet and outlet ports exceeds max.
