2. Whenever possible, the Sample Bypass flow control valve of the Genie membrane filter should be used to
minimize the sample lag time between the sample tap and the analyzer location. It can also be used as a
means to exhaust condensed liquids in the sample line away from the Genie filter and prevent a “loss of
flow” condition. Set a flow of 100-200cc/min. and vent to a safe area using ¼” O.D. tubing.
3. Connect to the Over-pressure Relief valve and vent to a safe area. The pressure relief valve is set at
Detcon to open at 15-20psig. For convenience sake, the sample bypass and over-pressure relief can be
vented together.
4. Install a length of ¼" OD stainless steel tubing from the vent port to an area deemed safe for venting as
shown below.
Venting pressure should be in the range of 0±1psig and ambient pressure is highly
preferred.
5. When the optional Acetic Acid Bubbler apparatus is used, prior to applying power and applying gas flow
the bubbler should be filled to the maximum fill level with a 5% acetic acid solution. (Standard white
vinegar is also acceptable).
