With the exception of purifiers containing AresKleen HCLP, HBRP or CDAP
material, all purifiers are supplied with an over-temperature indicator affixed
to the housing. This indicator should be monitored during conditioning. If the
indicator turns black discontinue conditioning by stopping flow of condition-
ing gas and initiating flow of inert gas, then contact Pall Corporation SLS for
technical assistance. For purifiers containing HCLP, HBRP or CDAP material,
the indicator is shipped in the purifier’s original packaging but it is not affixed
to the housing. During normal conditioning for service in HCl, HBr or CDA
the temperature of the purifier may increase enough to cause the indicator
to turn black. Therefore, Pall recommends that the indicator be affixed to the
purifier after completion of the conditioning process.
Note:
Before conditioning, verify that system is leak free and check 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 the no leaks are
found and the cylinder contents are correct, then proceed with
conditioning process.
