Page 37: Start-Up
A34310880_T - Operation Turn the gas-ballast control from two to six turns anti-clockwise to increase the gas- ballast from zero flow. Use gas-ballast flow: ▪ To pump high concentrations of condensable vapour. ▪ To decontaminate the oil. When operating the pump with the gas-ballast control open there will be an increased rate of oil loss from the pump. -
Page 38: To Pump Condensable Vapours
A34310880_T - Operation ▪ Use of an oil other than the recommended oil and the vapour pressure of the oil is higher than the specified ultimate vacuum of the pump. Use the following procedure to achieve ultimate vacuum: Isolate the pump from the vacuum system. Turn the gas-ballast control fully anti-clockwise (fully open) and operate the pump for at least 1 hour (or overnight) to thoroughly purge the oil of contaminants. -
Page 39: Shut-Down
A34310880_T - Operation When checking the pump, make sure that the pump is not going through a repetitive cycle of thermal overload failures and automatic resets.
