NOTE: Do not remove the nut from the union as the Teflon ferrules contained inside the nut
may be lost. See Figure 10.
4. Insert the tube stub from the gas bag into the knurled nut and tighten the
knurled nut and ensure the tube stub is secure.
If the gas bag is not secure, ensure you have inserted the tube stub far enough
into the knurled nut.
Do not over tighten the fitting.
NOTE: Over-tightening the Teflon ferrules will result in damage to the ferrules!
5. The union should be connected to the gas bag adapter, if it is not, then tighten
the nut on the adapter tube to the union.
6. Open the gas bag valve by turning the knurled plastic knob counterclockwise to
loosen it, then use the knurled collar on the valve tube to gently push the valve
tube toward the bag.
NOTE: Do not use the same gas bag or gas bag adapter for other compounds or calibration
mixes. You will contaminate the bag, the adapter and possibly the instrument.
7. Turn the regulator knob counterclockwise about half a turn to start the flow of
gas and fill the gas bag about half full and then close the regulator.
8. Disconnect the gas bag from the gas bag adapter and empty the bag.
9. Flush the bag a few times with the calibration gas and then fill it.
10. Close the gas bag valve, gently pull the valve tube up, then turn the knurled
plastic knob clockwise to tighten it against the valve tube.
11. Remove the knurled nut on the adapter tube from the regulator.
