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 safety precautions appropriate 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).
5. With purge gas flowing from the inlet line, remove the protective cap
from the inlet of the purifier (or inlet valve for the PG11000) and
immediately install the inlet gas line on the unit using a new gasket
(supplied with the purifier). Tighten the nuts until finger tight.
6. Gasket seating begins when there is sudden resistance to nut rotation.
Using an appropriate open-end wrench on the purifier and on the
connection nut (Ref. Table 3, last column), tighten per connection make
up instructions provided by the gasket seal supplier.
Note:
Gasket suppliers typically recommend that the connection nut be
rotated an additional 45 degrees (
⅛
turn) from the finger tight position
for nickel, silver-plated nickel, or stainless steel gaskets.
7. For PG11000, slowly open inlet valve. Allow purifier to come to
equilibrium with upstream gas supply pressure by introducing purge
gas into the unit (Pall recommends setting the purge gas supply
pressure between 30 – 60 psig, 0.21 – 0.41 MPa). Do not exceed
MAWP for purifier. Once equilibrated (this may take up to 10 minutes)
partially open outlet valve.
