A.15 Option 9b plumbing and connections
Option 9b uses two sc analyzers with two FILTRAX (FILTRAX 1
and FILTRAX 2). The samples of both FILTRAX go into the first sc
analyzer. This analyzer must change to the 2-parameter
configuration (see
Connect a 2-parameter option, page 66 ). Two
sample lines are going to both sc analyzers. Each sc analyzer is
discharging waste to an open drain.
Refer to Figure 37 and the following instructions for Option 9b:
1. Install both 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 FILTRAX 1 through the
analyzer ( Figure 37 , item 18). Use Seal Plug #1 to secure.
b. Feed the heated hose from FILTRAX 2 through the
analyzer (item 20). Use Seal Plug #1 to secure.
c. Feed two sample lines and one drain tube through the
analyzer. Use Seal Plug #3 to secure.
d. Remove the drain tube with the T-fitting from the valve
block connector.
e. Connect the drain tube to the valve block connector.
f. Connect the sample line from FILTRAX 1 to the bottom inlet
on Overflow Vessel 1 using the fittings (item 13).
g. Connect the sample line from FILTRAX 2 to the bottom inlet
on Overflow Vessel 2 using the fittings (item 12).
h. Change the analyzer to the 2-parameter configuration.
Refer to Connect a 2-parameter option, page 66 .
i. Connect Sample Line 1 to the reworked overflow of
Overflow Vessel 1. Connect Sample Line 2 to the reworked
overflow of Overflow Vessel 2.
3. Install the second sc analyzer (Analyzer 2):
a. Feed the two sample lines from the two overflow vessels of
Analyzer 1 through Analyzer 2. Use Seal Plug #3 to secure.
b. Feed the drain tube though Analyzer 2 (item 6). Use Seal
Plug #3 to secure.
c. Use Seal Plug #3 to seal the unused opening.
d. Connect the drain tube to the T-fitting.
e. Connect Sample Line 1 from Analyzer 1 to the bottom inlet
on Overflow Vessel 1 using the fittings.
f. Connect Sample Line 2 from Analyzer 1 to the bottom inlet
