moisture in the form of vapor from the pump. To use the gas ballast, start the pump and open the gas ballast valve until the system has reached approximately 1000–3000 microns. Close the valve to allow the pump to pull down to its ultimate vacuum level. The gas ballast valve is loed beside the handle, opposite the inlet fitting.
The gas ballast should also not be used when pumping toxic compounds, as the gas ballast introduces a leak into the room air, if the pump is turned off, a small amount of vapors from inside the pump could potentially leak out through the gas ballast port into the room air. These Edwards nXDS gas ballast purge adapters have part nuer A735-01-809.
