Page 4: Safety Information
page 4 of 26 Safety information! General information ☞ Read and comply with this manual before installing or operating the equipment. NOTICE ☞ Transport the pump at the provided handles. Remove all packing material, remove the product from its packing-box, remove the protective covers from the inlet and outlet ports and keep, inspect the equipment. -
Page 5: Ambient Conditions
page 5 of 26 • Comply with maximum permissible pressures at inlet and outlet and pressure differences, see section ”Technical data”. Do not operate the pump with overpres- sure at the inlet. • Check that mains voltage and current conform with the equipment (see rating plate). -
Page 6: Operating Conditions
page 6 of 26 Operating conditions ➨ The pumps have no approval for operation in or for pumping of potentially explosive atmospheres. ➨ The pumps 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. -
Page 7: Maintenance And Repair
page 7 of 26 • Attention: Due to soiling of the silencer an internal overpressure may build up, which can damage bearings, diaphragms and valves. Preferably use the hose noz- zle as outlet and make sure that the exhaust pipeline cannot become blocked. •... - Page 8 page 8 of 26 • Check every capacitor regularly by measuring its capacity and estimating its op- eration time. Exchange old capacitors early enough to prevent a failure. If an overaged motor capacitor fails it might get hot and even melt and may cause a flame to form which could be dangerous for persons and equipment in the vicinity.

Page 13: Use And Operation
page 13 of 26 Use and operation Installing in a vacuum system • Connection lines at the pump inlet have to be gas tight. Particles and dust must not be aspirated, the user has to provide appropriate filters if necessary. The user must ensure their suitability concerning gas flow, chemical resistance and safe- ness against clogging prior to use. -
Page 14: Shutdown
page 14 of 26 • Due to the high compression ratio of the pumps, the pressure at the outlet port might get higher than the maximally permitted pressure compatible with the me- chanical stability of the system. Ensure that the pump outlet is not blocked or restricted. -
