Note:
If the surface temperature of the purifier feels very warm to the
touch at any time during the installation or conditioning procedure,
immediately stop gas flow, recheck for leaks and recheck that the
contents of the gas cylinder / gas source match the intended process
gas for use in the purifier (as per the product part #). If no leaks are found
and the cylinder contents are correct, then resume gas flow.

service by flowing 2.0 slpm (4.2 scfh) of 100% process gas through
the unit for 60 minutes.
Note:
During the conditioning, the surface temperature of the purifier may
feel warm to the touch. If the purifier feels hot, continue conditioning by
reducing the gas flow rate or introducing an inert gas to create a dilute
blend until the elevated temperature subsides then return to previous
conditioning parameters. No damage to the purification material or
purifier is expected. Once the unit has completely cooled, the purifier is
ready for service.
