8. Remove the protective cap from the outlet end of the purifier.
9. If purge gas flow is not detected from the outlet end of the unit, increase
gas pressure or flow rate until gas is detected (for the PG11000, opening
the outlet valve more may be necessary to initiate purge gas flow).
10. Connect the outlet end of the purifier to the process gas delivery line
leading to the equipment using a new gasket (supplied with the purifier).
Tighten the nuts until finger tight and tighten the fitting as in Steps 5
and 6.
11. Open the isolation valve downstream of installation zone. Ensure the
gas flow path in the outlet gas line is open to vent or scrubber.
12. Continue the flow of inert gas for 5 – 10 minutes.
13. Unit is now ready for helium leak testing.
PG550-MAN, PG2400-MAN, PG11000, and PG11000-MAN:
1. Start inert gas purge flow (Ref. Table 3, middle column) to the installation
zone by opening an upstream valve.
MAINTAIN
purge gas flow until
the installation of assembly is complete.
2. If necessary, remove and dispose of existing component (or spool
piece) by disconnecting fittings upstream and downstream of the
component, removing the component and gaskets, and capping the
component end connections. Use appropriate safety precautions for
the type of process gas being purified.
3. Inspect sealing surface(s) of the gas line fittings. If damage exists,
replace the fittings.
4. Attach the supplied gas specific sticker to the aluminized label on
purifier assembly (if applicable).
