CAUTION
Gas flow must be maintained at all times for units with IZS Options installed. The IZS option includes a
permeation tube which emits H2S. Insufficient gas flow can build up H2S to levels that will damage the
instrument.
Remove the permeation device when taking the analyzer out of operation.
