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

  • Page 26: To Decontaminate The Oil

    The overload device resets automatically when the motor has cooled. When checking 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.
