chamber. One wrench must be used to back up the force applied to tighten the fitting (direct wrench
force will bend the stem).
Sample will spill or leak out during this procedure. Consult MSDS sheets on file at
your location for safety requirements.
Sample valve repair may necessitate the venting of flammable substances into the
atmosphere surrounding the analyzer. Remove power from all sources of ignition
in the immediate area. Do not open any purged enclosures that remain powered.
Ensure proper safety equipment is worn, such as rubber gloves and face shield or
safety glasses.
It is the customer's responsibility to ensure that the area is safe and and hazard-
free, and will remain so the entire time the analyzer is open. This responsibility
includes ensuring adequate ventilation in analyzer shelter and obtaining proper
work permits, etc.
See "AIR PURGING" in Section 4 for the X Purge override function. Do not perform
override until you have read Section 4 completely and you understand and can
perform the procedure properly.
To ensure the integrity of the components within the Liquid Sample Valve (LSV),
