If it is contaminated also indicate the nature of the hazard. Leybold must return any pumps without a „Declaration of Contamination“ to the sender’s address. Disposal of waste oil Under the amended law relating to waste disposal dated November 1, 1986 (valid in the Federal Republic of Ger- many) the disposal of used oil is subject to new provi- sions. According to legislation relating to waste disposal the so-called principle of causality is applied. Hence, anyone in possession of used oil is responsible for its proper disposal. Used oils coming from vacuum pumps must not be mixed with other substances. Used oils from vacuum pumps (LH-oils on the basis of mineral oils) having been affected by normal contamina- tion due to oxygen from the ambient air, increases in temperature and mechanical wear, must be disposed of as used oil in accordance with the regulations. Used oils from vacuum pumps that have been contami- nated by other substances must be labelled, stored and disposed of as special waste with reference to the kind of contamination. If you send a pump to LEYBOLD for repair please indi- cate any harmful substances existing in the pump oil or around the pump. When disposing of used oil please observe the safety regulations that are valid in your country. We reserve the right to modify the design and the speci- fied data. The illustrations are not binding. 3 GA 03.108/14.02 - 01/03 4 GA 03.108/14.02 - 01/03 Safety considerations IMPORTANT SAFETY CONSIDERATIONS The Leybold RUVAC vacuum pump is designed for safe and efficient operation when used properly and in accordance with this manual. It is the responsibility of the user to carefully read and strictly observe all safety precautions described in this section and throughout the manual. This product must be ope- rated and maintained by trained personnel only. Consult local, state, and national agencies regarding specific requirements and regulations. Address any further safety, operation and/or maintenance que- stions to your nearest Leybold Vacuum office. Warning Failure to observe the following precautions could result in serious personal injury. • Before beginning with any maintenance or service work on the RUVAC, disconnect the pump from all power supplies. • Do not operate the pump with any of the covers removed. Serious injury may result. • If exhaust gases must be collected or contained, do not allow the exhaust line to become pressurized. • Make sure that the gas flow from the exhaust port is not blocked or restricted in any way. • The standard version of the RUVAC is not suited for operation in explosion hazard areas. Contact us before planning to use the pump under such circumstances. • Before starting up for the first time, the motor circuit must be equipped with a suitable protective motor switch. Please take note of the information in these Operating Instructions or on the electric motor (wiring diagram). • The RUVAC is not suited for pumping of - combustible and explosive gases or vapours - radioactive and toxic substances - pyrophorous substances. • The RUVAC must be integrated in the system control arrangement so that the pump can not run-up automatically after it has been shut down by the temperature switches in the motor. This applies equally to emergency shut-down arrangements. After having determined the fault cause, the pump should be switched on manually again. • Avoid exposing any part of the human body to the vacuum. • Never operate the RUVAC without a connected intake line or blank flange. • The location at which the RUVAC (including its accessories) is operated should be such that angles over 10° from the vertical are avoided. • The location of the RUVAC should be such that all controls are easily accessible. • Under certain ambient conditions the RUVAC may attain a temperature of over 80 °C (176 °F). There then exists the danger of receiving burns. Note the symbols on the pump pointing to the hazards, and in the case of a hot pump wear the required protective clothing.
