5. Remove the (6) M6 x 50 screws and carefully separate the Filterblock
into three sections.
6. Inspect both Membrane Filters for damage, particulate, and liquid,
oils, or waxes.
The High-Flow Membrane Filter is bonded to its o-ring – do not at-
tempt to separate them. If they become separated, replace them with
new parts.
The Type-5 Membrane Filter and its o-ring are two separate pieces.
These parts can be re-used (after they have been cleaned) at the
6-month cleaning interval if only liquids are found. However, if
they are damaged (are creased, have holes, or are transparent) or if liq-
uids have been forced through them (liquids, oils, or waxes are present
in the filters), replace with new parts. Always replace the Membrane
Filters, o-rings, and Flow Restrictors annually.
If there is liquid, oil, or wax in the filter sections of the Filterblock,
you may also need to clean the Measuring Cell, mirror, and tubing
between the Filterblock and Measuring Cell.
When removing o-rings or parts with o-rings, use an o-ring removal
tool.
Carefully remove the (1) High-Flow Membrane Filter and its attached
o-ring (P/N 300-5862, c/w #216 o-ring) from the Center Filterblock.
Carefully remove the (1) Type-5 Membrane Filter and its o-ring
(P/N 300-8594, c/w #216 o-ring) from the Back Filterblock.
7. Carefully remove the (2) small #006 o-rings (P/N 300-6244) and (2)
Sintered Disks from the Center and Back Filterblock sections.
8. Remove the 50 cc/min Flow Restrictor fitting (P/N 300-6245), the
1/8-NPT Plug (P/N 300-5774), and the Male Connector (Vent to Flare,
P/N 300-1239) from the three Filterblock sections.
Remove the (3) 15 cc/min Flow Restrictors (one on each section). Be
careful not to damage the 1/8" NPT threads. Remove the (3) #008
o-rings, one from each Flow Restrictor.
If previous sample gas flow rates suggest possible plugging of the
Filterblock Flow Restrictors are plugged, replace them with new ones.
