Page 4: Safety Information
☞ Make sure that the individual components are only connected, combined and op- erated according to their design and as indicated in the instructions for use. Use only original VACUUBRAND accessories. ☞ Comply with notes on correct vacuum and electrical connections, see section ”Use and operation”. -
Page 5: Ambient Conditions
page 5 of 31 ☞ Do not permit any uncontrolled pressurizing (e.g. make sure that an exhaust pipeline cannot become blocked). Risk of bursting! ☞ Due to the high compression ratio of the pumps, pressure at the outlet port might be generated being higher than the maximum permissible pressure compatible with the mechanical stability of the system. -
Page 6: Safety During Operation
page 6 of 31 ➨ The devices are not suitable to pump unstable substances and substances which react explosively under impact (mechanical stress) and/or when being exposed to elevated temperatures without air, self inflammable substances, substances which are inflammable without air and explosive substance •... - Page 7 page 7 of 31 • Use the system only in combination with the integrated hydrophobic filter (steriliz- able) to protect pump and environment (people). • Comply with applicable regulations when disposing of chemicals. Take into con- sideration that chemicals may be polluted. Take adequate precautions to protect people from the effects of dangerous substances (chemicals, thermal decompo- sition products of fluoroelastomers), wear appropriate safety-clothing and safety glasses.

Page 8: Maintenance And Repair
page 8 of 31 Maintenance and repair Wear parts have to be replaced regularly. In case of normal wear the lifetime of NOTICE the diaphragms and valves is > 10000 operating hours. Bearings have a typical du- rability of 40000 h. Motor capacitors have a typical durability in the range of 10000 to 40000 h depending strongly on the operation conditions like ambient temperature, humidity or load. -

Page 13: Use And Operation
page 13 of 31 Use and operation Installation • It is imperative to remove the transportation lock prior to use! Tilt device care- fully onto the side. Remove the four locking screws (wing screws) next to the fan guard at the base plate. Put device back to normal operating position and keep the locking screws. - Page 14 page 14 of 31 Attention: In case of supply voltage below 100V, the lock of the cutout might be restricted and the pump might restart on its own after sufficient cooling down. Take suitable precautions, if an automatic restart of the pump may lead to a critical dan- gerous situation.

Page 15: Shutdown
page 15 of 31 Shutdown Short-term: NOTICE Has the pump been exposed to condensate? Allow the pump to continue to run at atmospheric pressure for a few minutes. Has the pump been exposed to media which may damage the pump materials or form deposits? Check and clean pump head if necessary. -
Page 16: Vacuuhandcontrol Vhc
page 16 of 31 VacuuHandControl VHC The instrument allows the aspiration of excess liquids. The VHC is supplied completely with three differ- ent adapters (included in delivery) to hold with pasteur pipettes, capillaries and pipette tips (100 µl). Before aspiration: Push back the locking ring from the control button. - Page 17 page 17 of 31 The hydrophobic filter retains water and aqueous solutions also in the form of aerosols. When using solvents or due to evaporation of water, condensate may be recovered in the separator. ☞ Remove separator and drain condensate in case. Important: Comply with applicable regulations when dispos- ing of solvents.

Page 20: Replacing Diaphragms And Valves
page 20 of 31 Replacing diaphragms and valves All bearings are encapsulated and are filled with long-life lubricant. Under normal ope- NOTICE rating conditions, the pump is maintenance free. The valves and diaphragms as well as the motor capacitors are wear parts. If the rated ultimate vacuum is no longer achieved or in case of increased noise level, the pump interior, the diaphragms and the valves must be cleaned and the diaphragms and valves must be checked for cracks or other damage. -
