6.3.5
Purge Air Exhaust Vent
Connect tubing or pipe of an appropriate material from port labeled Purge Exhaust to a permanent vent
designed for this type of discharge. 1/2” I.D. tubing can be used for runs up to 30 feet. Too small of an ID
and/or too long of a piping run may cause inadequate purge vacuum performance and/or collapse of the PD
sample gas dryer membrane tubes resulting in poor drying performance and/or high sample gas flow
restriction.
6.3.6
Sample Gas Bypass Port
This port is included on the PCD-3000-PR and PCD-3000-PR-CD models and is capped at the factory. It is
typically used to decrease the system response time in applications where the sample gas is under pressure.
Use of this function is optional.
WARNING!
FAILURE TO PROPERLY VENT THE SYSTEM MAY RESULT IN PERSONAL INJURY AND/OR
PROPERTY DAMAGE!
The gas exhausted from the purge exhaust port under normal operation is humid air. However, in the
event of an internal failure of the PD sample gas PD dryer installed in the system, the exhaust may
contain sample gas that may be hazardous. The purge exhaust must be permanently routed to a vent
system or directly outdoors. Do not allow the purge to vent into a structure or confined space.
