Using the gas ballast valve
• Ensure that when the gas ballast valve is
open, the air/gas that enters through the
gas ballast valve doesn’t come in contact
with any hazardous, explosive or other-
wise dangerous mixtures that the vacuum
pump is pumping at its inlet.
• Venting the receptacles or the vacuum
pump using ambient air may under some
circumstances create a risk of serious dam-
age to the equipment and/or surrounding
installations and a risk to personnel of
serious injury or even death, due to the
formation of hazardous and/or explosive
mixtures if a reaction between the air and
the medium that is being pumped occurs
either within the pump or at its outlet.
For pumping condensable vapours (water vapour, solvents,
etc.):
• Let pump run with gas ballast valve closed until pump
reaches its operating temperature.
• Open gas ballast valve (refer to figure below).
Open
• Gas ballast valve is open when the notch on the cap is
aligned with the notch on the nozzle (Gas ballast valve
can be closed by rotating cap at least 90°).
• When gas ballast valve is opened, ultimate vacuum will be
reduced and pumping speed will decrease.
• Use inert gas at air inlet to avoid formation of explosive
mixtures.
