  • Page 18: Installation

    The E-LAB 2 is not recommended for pumping hazardous substances. You must ensure that the E-LAB 2 is suitable for your application. If you have any doubt as to the suitability of the E-LAB 2 for your application, refer to the Edwards guidelines on vacuum pump and vacuum system safety (see the Associated publications at the end of the Contents list at the front of this manual).

  • Page 19: Unpack And Inspect

    Locate the pump The E-LAB 2 has a lifting handle which you can use to move the pump by hand. If you wish to use mechanical lifting equipment, do not attach the equipment to the handle; for stability, use slings around the motor and the pump-body.

  • Page 30: Operation

    Use the following procedure to achieve ultimate vacuum: 1. Isolate the E-LAB 2 from your vacuum system and operate the E-LAB 2 for at least 1 hour (or overnight) to thoroughly purge the oil of contaminants.

  • Page 31: To Decontaminate The Oil

    The overload device resets automatically when the motor has cooled. When you check the E-LAB 2, make sure that the pump is not going through a repetitive cycle of thermal overload failures and automatic resets. If necessary, reduce the thermal load from the pumped gases, to prevent overheating of the pump.
