page 12 of 74 and +40°C). Periodically check maximum temperatures if installing the pump in a cabinet or a housing. Make sure ventilation is adequate to maintain recommended operating temperature. 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 74 + 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 of...
Page 14: Ambient Conditions
page 14 of 74 pump is connected to AC power. Unplug the pump be- fore setting the voltage selection switch. Note: If the pump is switched on with wrong voltage selection, the motor may be damaged! • Ensure that the coolant outlet pipe is always free and that it cannot get blocked.
Page 15: Operating Conditions
page 15 of 74 + P ay attention to the maximum permissible ambient and gas inlet temperatures (see ”Technical data”, pg. 24). • Adopt suitable measures in case of differences from recommended conditions, e.g., using the equipment outdoors, installation in altitudes of more than 6500 ft (2000 m) above mean sea level, conductive pollution or external condensation on the pump.
Page 16 page 16 of 74 Do not pump: - unstable substances - substances which react explosively under impact (mechanical stress) without air - 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.
Page 17: Safety During Operation
page 17 of 74 Safety during operation ➨ Adopt suitable measures to prevent the release of dan- gerous, toxic, explosive, corrosive, noxious or polluting fluids, vapors and gases. To prevent any emission of such substances from the pump outlet, install an ap- propriate collecting and disposal system and take pro- tective action for pump and environment.
Page 18 page 18 of 74 roelastomers). Use appropriate protective clothing and safety goggles. + Use only original manufacturer’s spare parts and accessories. Otherwise the safety and performance of the equipment, as well as the electromagnetic compat- ibility of the equipment might be reduced. The CE mark or the cTÜVus mark may be voided if not using original manufacturer’s spare parts.
Page 19 page 19 of 74 from hot surfaces or electric sparks. Ensure that hot surfaces of the pump do not cause burns. Provide a suitable contact guard if necessary. • Ensure that the coolant outlet pipe at the waste vapor condenser is always free and that it cannot get blocked. Do not start the pump if the pressure difference between NOTICE inlet and outlet exceeds 16 psi (1.1 bar) at maximum.
Page 20: Maintenance And Repair
For details and for the online ”Instructions for repair” man- ual see www.vacuubrand.com. In case of normal wear, the lifetime of the diaphragms and valves is > 10000 operating hours. Bearings have a typical durability of 40000 h.
Page 21 page 21 of 74 + Never operate a defective or damaged pump. + Check every motor capacitor regularly by measuring its capacity and estimating its time in operation. Re- place old capacitors early enough to prevent a failure in operation. If an old motor capacitor fails, the capacitor may get hot.
Page 22: 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 23 page 23 of 74 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 74 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 74 • 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. • Pump with dual-voltage motor: Check that the volt- age selection switch at the terminal box is positioned correctly.

Page 42: During Operation
page 42 of 74 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 74 its. Clean the pump if necessary to avoid an increase of the pump’s operating temperature. Operation with silencer (optional) at the outlet: Operating the pump at a high inlet pressure or pumping dusty gases for a long time may cause clogging of the silencer. Check the silencer regularly and replace if necessary.
Page 44: Important Notes Regarding The Use Of Gas Ballast
page 44 of 74 Important notes regarding the use of gas bal- last 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.
Page 45: Important Notes Concerning The Operation Of The Exhaust Waste Vapor Condenser
page 45 of 74 In case of low boiling solvents (when the formation of con- densate is unlikely), the use of gas ballast might be unnec- essary. Operating the pump without gas ballast increases the solvent recovery rate at the exhaust waste vapor con- denser.
Page 46 46 of 74 overfill. Drain catchpots in time to avoid overflow. Install a level sensor (see ”Accessories”, pg. 48) for monitoring, if necessary (VACUUBRAND controller CVC 3000 or VNC 2 is required). The maximum liquid level is at approximately 80% of the total filling level to avoid problems when removing the catchpots.
Page 47: Shutdown & Storage
page 47 of 74 Shutdown & storage The pump can be switched off under vacuum. Short-term: NOTICE Has the pump been exposed to condensate? Allow the pump to continue to run at atmospheric pres- sure for a few minutes. Has the pump been exposed to media which may damage the pump materials or form deposits? Check and clean pump heads if necessary.
