Page 5 page 5 of 29 Comply with all relevant safety requirements (regulations and guidelines) and adopt suitable safety measures. The mains on/off switch is located sidewise at the terminal box. The pumps cannot be hooked up separately. ☞ If the equipment is brought from cold environment into a room for operation, allow the equipment to warm up (pay attention to water condensation on cold surfaces).
Page 6 page 6 of 29 The pumps are not suitable for pumping substances which may form deposits inside the pump. ☞ If there is a danger of the formation of deposits in the pump chamber (check inlet and outlet of the pump) inspect the pump chamber regularly and clean if necessary. 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 page 7 of 29 ☞ If the diaphragm pump is shut down, the Roots pump is not shut down automati- cally. However, the variable speed drive of the Roots pumps of the pumping units RP 15C/22C/35C VARIO reduces the speed of the Roots pump following a limiting current regulation, if necessary to standstill of the Roots pump.
Page 8 page 8 of 29 The A-weighed emission sound pressure level of the pump does not exceed 70 dB(A). Measurement according to EN ISO 2151:2004 and EN ISO 3744:1995 with standard silencer or exhaust tube at outlet. Ensure that maintenance is done only by suitable trained and supervised techni- cians.

Page 12: Use And Operation
page 12 of 29 Use and operation Installation in a vacuum system ☞ Avoid throttling losses by using connecting pipes with large diameter and keep them as short as possible. ☞ Reduce the transmission of vibration and prevent loading due to rigid pipelines. Insert elastic hoses or flexible elements as couplings between the pump and rigid pipes.
Page 13 page 13 of 29 ☞ The frequency is reduced at high inlet pressures (especially at atmospheric pres- sure) in order to avoid thermal overload of the roots pump. ☞ Under normal conditions, the maximum pump speed is reached only at inlet pres- sures <...

Page 16: Oil Change
page 16 of 29 Oil change Before starting maintenance, isolate the pump from the vacuum system and the elec- trical supply so that the pump cannot be operated accidentally. Has the pump been exposed to dangerous or corrosive gases? Take appropriate safety measures (e. g. safety-clothing and protective goggles) to avoid inhalation and skin contact.
Page 17: Replacing Diaphragms And Valves
page 17 of 29 Replacing diaphragms and valves All bearings are encapsulated and are filled with long-life lubricant. Under normal opera- ting 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.

Assembling pump heads ➨ By turning eccentric bushing (front of connecting rod), bring connecting rod into a position in which diaphragm is in con- tact with housing and centred with respect to bore.
Page 21 page 21 of 29 Individual performance check of a pump head : By measuring the pressure at the inlet port of the individual head: Use a suitable vacuum gauge (e. g. DVR 2, cat. no.: 68 29 02), make sure that it is correctly calibrated, and measure the pres- sure at the inlet port.
