Commissioning and decommissioning 6.1.1 Installation check WARNING Risk of injury! A faulty installation as well as missing or non-functional safety equipment may lead to severe injury. Ø Put the vacuum pump into operation only after it has been ensured that the installation is carried out flawless and the requirements for installation, as- sembly and electrical installation have been observed.
Commissioning and decommissioning Property damage due to formation of condensate and impurities! NOTICE Due to increased condensate formation and impurities, deposits may adhere to the rotors and the compressor casing after switching off the machine, preventing the start-up when restarting it. Condensate and impurities can cause damage to the machine.
5,000 operating hours . The specified interval of up to 20,000 operating hours only applies to types of oil delivered or approved by Elmo Rietschle. For all works, observe the safety instructions described in chapter 2 “Safety” .
Motor (maintenance, lubrication and cleaning) 7.7.1 instructions Frequency converter 40,000 h General overhaul of the machine (Elmo Rietschle Service) — Tab. 1 Maintenance table Preparing maintenance works a) Switch the plant off electrically and secure it against unexpected restart. b) Vent the vacuum pump with atmospheric air; for this purpose open the shut-off valve.
Maintenance and repair Lubricating Oil CAUTION Risk of burns on hot equipment! There is the risk of burning on hot equipment when changing oil. Ø Allow the machine to cool down to approx. 40 °C (lukewarm). Ø Avoid contact with the hot oil because the oil temperature can be higher than the ambient external temperature of machine.
Maintenance and repair We recommend using Elmo Rietschle oils: GEAR-LUBE 150: Synthetic oil, highly loadable with high resistance to aging and with excellent wear pro- tection The viscosity of the oil used must comply with ISO VG 150 as per DIN 3448.
