IMPORTANT SAFETY CONSIDERATIONS
The Leybold TRIVAC E vacuum pump is designed for safe and efficient operation when used properly and in accor-
dance 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 operated and maintained by trained per-
sonnel only. Consult local, state, and national agencies regarding specific requirements and regulations. Address any
further safety, operation and/or maintenance questions 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 TRIVAC E, 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 pressurised.
• Make sure that the gas flow from the exhaust port is not blocked or restricted in any way.
• The standard version of the TRIVAC E 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 (3 phase) must be equipped with a suitable pro-
tective motor switch. Please take note of the information in these Operating Instructions or on the elec-
tric motor (wiring diagram).
• The TRIVAC E is not suited for pumping of:
- combustible and explosive gases or vapours
- radioactive and toxic substances
- pyrophorous substances.
- oxidations substances.
• Avoid exposing any part of the human body to the vacuum.
• Never operate the TRIVAC E without a connected intake line or blank flange.
• The location at which the TRIVAC E (including its accessories) is operated should be such that angles
over 10° from the vertical are avoided.
• The location of the TRIVAC E should be such that all controls are easily accessible.
• Under certain ambient conditions the TRIVAC E 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 requi-
red protective clothing.
• Before pumping oxygen (or other highly reactive gases) at concentrations exceeding the concentration
in the atmosphere (> 21 % for oxygen) it will be necessary to use a special pump. Such a pump will
have to be modified and de-greased, and an inert special lubricant (like PFPE) must be used.
