Figure 3-6: Basic Pneumatic Connections for Units With Valve Options
Once the appropriate pneumatic connections have been made, check all pneumatic fittings
for leaks using the procedures defined in Section 11.5.
WARNING
Gas flow must be maintained at all times for units with IZS Options installed. The
IZS option includes a permeation tube which emits NO
2
. Insufficient gas flow can
build up NO
2
to levels that will damage the instrument. Remove the permeation
device when taking the analyzer out of operation.
