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 66 ). 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.

1. Install the FILTRAX into the sample stream. Refer to the
FILTRAX User Manual for more information.

analyzer opening ( Figure 30 , 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.
