Page 12: Setting Up And Installing The Equipment
page 12 of 70 + 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 70 + 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 14: Ambient Conditions
page 14 of 70 • 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. Make sure ventilation is adequate to maintain recommend- NOTICE ed operating temperature. Keep a minimum distance of 2 in (5 cm) between the cooling fan and surrounding items (e.g., housing, walls, etc.), or else install an external au- tomatic ventilation system. -
Page 15: Operating Conditions

Page 16: Safety During Operation
page 16 of 70 - substances which react explosively when being ex- posed to elevated temperatures without air, - substances subject to auto-ignition, - substances which are inflammable without air - explosive substances. ➨ The pumps are not approved for operation below ground. - Page 17 page 17 of 70 of such substances from the pump outlet, install an appropriate collecting and disposal system and take protective action for pump and environment. ➨ You must take suitable precautions to prevent any for- mation of explosive mixtures in the pump chamber or at the outlet of the pump.
- Page 18 page 18 of 70 + 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 70 + Take adequate precautions to protect people from the effects of dangerous substances if contamination has occurred. Use appropriate protective clothing, safety goggles and protective gloves. + Wear parts have to be replaced regularly. + Never operate a defective or damaged pump. + Check every motor capacitor regularly by measuring its capacity and estimating its time in operation.

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 70 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 31: During Operation
page 31 of 70 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 32 page 32 of 70 Do not start the pump if the pressure difference between NOTICE inlet and outlet ports exceeds max. 16.0 psi (1.1 bar). Attempts to start the pump at higher pressure difference may cause stalling and damage of the motor. Prevent internal condensation, transfer of liq- condensate / dust uids or dust.
