The Membrane Filters, o-rings, Sintered Disks, and Flow Restrictors can
be re-used, unless they are damaged (are creased, have holes, or are
transparent) or contaminated (with liquids, oils, or waxes); in this case,
replace with new parts.
Be extremely careful not to damage the new Membrane Filters.
The High-Flow Membrane Filter is bonded to its o-ring at the factory –
do not attempt to separate them.
With the membrane side of the Back Filterblock section facing up, install
one (1) cleaned (or new, Part No. 300-6257) Sintered Disk into its recess.
Install one (1) new #006 o-ring (Part No. 300-6244) in the o-ring groove.
Carefully install one (1) cleaned (or new, Part No. 300-8594, comes with
separate #216 o-ring) Type-5 Membrane Filter by centring the Membrane
over the Sintered Disk and the o-ring groove. Place the o-ring over the
Membrane and gently press the o-ring into the groove in one location.
Continue with the section across from the first location and gently press
the o-ring into the groove. Continue alternating locations/pressing until
the o-ring is completely seated in its groove and the Membrane is tightly
stretched.

groove. Carefully install one (1) cleaned (or new, Part No. 300-5862, comes
with attached #216 o-ring) High-Flow Membrane Filter by centring the
Membrane/o-ring over the Sintered Disk and the o-ring groove (o-ring side
up). Gently press the o-ring into the groove using the same method as the
Type-5 Membrane Filter, until the o-ring is completely seated in its groove
and the Membrane is tightly stretched.
