Option 4 uses two sc analyzers with the FILTRAX. The sample from
the FILTRAX goes to the first analyzer which needs to change to a
2-parameter configuration (see
Connect a 2-parameter option,
page 78 ). The heated drain hose connects both sc analyzers.The
waste from both analyzers is discharged back into a drain through
the second heated drain hose.
Refer to Figure 32 and the following instructions for Option 4:
1. Install the FILTRAX into the sample stream. Refer to the
FILTRAX User Manual for more information.
2. Install the first sc analyzer (Analyzer 1):
a. Feed the heated hose from the FILTRAX through the
analyzer opening ( Figure 32 , item 15). Use Seal Plug #1
to secure.
b. Feed the heated drain hose though the analyzer opening
(item 17). Use Seal Plug #1 to secure.
c. Seal the remaining opening with Seal Plug #3.
d. Connect the heated drain power connections. Refer to
section 3.5.5, page 27 .

inlet on the overflow vessel using the fittings.
