Page 12: Setting Up And Installing The Equipment
page 12 of 56 + Do not use the pump to generate pressure. + The pumps are designed for ambient temperatures during operation between +50°F and +104°F (+10°C and +40°C). Periodically check maximum tempera- tures if installing the pump in a cabinet or a housing. Make sure ventilation is adequate to maintain recom- mended operating temperature. - Page 13 page 13 of 56 + Due to the high compression ratio, the pump may gen- erate overpressure at the outlet. Check pressure com- patibility with system components (e.g., exhaust pipe- line or exhaust valve) at the outlet. + Do not permit any uncontrolled pressurizing. Make sure that the exhaust pipeline cannot become blocked.

Page 17: Safety During Operation
page 17 of 56 Safety during operation ➨ Adopt suitable measures to prevent the release of dan- gerous, toxic, explosive, corrosive, noxious or pollut- ing fluids, vapors and gases. To prevent any emission of such substances from the pump outlet, install an appropriate collecting and disposal system and take protective action for pump and environment. - Page 18 page 18 of 56 + Interruption of the pump (e.g., due to power failure), failure of connected components or of parts of the sup- ply, or change in parameters must not be allowed to lead to dangerous conditions. In case of a diaphragm failure or in case of a leak in the manifold, pumped substances might be released into the environment or into the pump housing or motor.

Page 19: Maintenance And Repair
For details and for the online ”Instructions for repair” man- ual see www.vacuubrand.com. In normal use, the lifetime of the diaphragms and valves is typically 15,000 operating hours. Bearings have a typi- cal durability of 40000 h. - Page 20 page 20 of 56 ➨ Ensure that the pump cannot be operated acciden- tally. Never operate the pump if covers or other parts of the pump are disassembled. ➨ Switch off the pump. Disconnect the electrical power cord and wait five seconds before starting maintenance to allow the capacitors to discharge.

Page 21: Important Information: Equipment Marking (Atex)
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not comply with the classifi- cation of the VACUUBRAND equipment, the specified category of the VACUUBRAND equipment is no longer valid.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 22 page 22 of 56 • The equipment is designated for an ambient and gas inlet temperature during operation of +10 to +40°C. Never exceed these ambient and gas inlet temperatures. If pumping / measuring gases which are not potentially explosive, extended gas inlet temperatures are permissible. See instructions for use, section “Gas inlet temperatures”...

Page 31: Important Notes Regarding The Use Of Gas Ballast
Turn gas ballast cap to open valve. For condensable vapors (water vapor, sol- vents, etc.): - ME 16C / MZ 8C / MD 8C: The gas ballast valve is open if the arrow on the gas ballast cap is pointing towards the side of the pump with the rating plate. -
Page 32: Shutdown & Storage
page 32 of 56 - With gas ballast valve open, the ultimate vacuum will be reduced. - Use inert gas for gas ballast to avoid the formation of explosive mixtures. Attention: maximum supply pres- sure of inert gas: 17.5 psi (1.2 bar) absolute. - Close the gas ballast valve by turning the cap 180°. -
