page 4 of 27 Safety information! General information Read and comply with this manual before installing or operating the equipment. NOTICE Transport the pump at the provided handle. 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 of 27 ☞ Avoid overpressure of more than 0.2 bar in case inert gas is connected to the pump, the gas ballast connection or to a venting valve. Comply with maximum permissible pressures at inlet and outlet and pressure •...
page 6 of 27 • The pumps are not suitable for pumping substances which may form deposits inside the pump. Deposits and condensate in the pump may lead to increased temperatures even to the point of excessing the maximum permitted tempera- tures! •...
page 7 of 27 • Due to the residual leak rate of the equipment, there might be an exchange of gas, albeit extremely slight, between the environment and the vacuum system. Adopt suitable measures to prevent contamination of the pumped substances or the environment.

page 12 of 27 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 13 of 27 During operation • Maximum ambient temperature: 40 °C • Make sure ventilation is adequate if pump is installed in a housing or if ambient temperature is elevated. • Potentially dangerous gases or vapours at the outlet of the pump have to be drained and disposed appropriately.
page 14 of 27 In case of condensable vapours (water vapour, solvents, ...): ☞ Do not pump vapour until the pump has reached its opera- ting temperature. ☞ Open gas ballast valve. The gas ballast valve is open if the arrow on the gas ballast cap shows towards the pump.

page 17 of 27 Replacing diaphragms and valves All bearings are encapsulated and are filled with long-life lubricant. Under normal NOTICE operating conditions, the pump is maintenance free. The valves and diaphragms 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.
