A.13 Option 8b plumbing and connections
Option 8b uses two sc analyzers with the FILTRAX. The sample of
the FILTRAX goes to the first sc analyzer. This analyzer must use
the 2-parameter configuration (see
A.2 on page 64 ). Each
sc analyzer discharges waste into an open drain.
Refer to Figure 35 and the following instructions for Option 8b:
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 35 , item 8). Use Seal Plug #1
to secure.
b. Feed the drain tube through the analyzer opening (item 6)
and to an open drain below Analyzer 1. Use Seal Plug #3
to secure.
c. Change the analyzer to the 2-parameter configuration.
Refer to
2-parameter configuration on page 64 .
d. Connect the reworked overflow of the overflow vessel to
deliver the sample to Analyzer 2.
e. Feed the overflow vessel tubing (item 11) through
Analyzer 1 to Analyzer 2. Use Seal Plug #3 to secure.
f. Remove the drain tube with the T-fitting from the valve
block connector. This drain tube is not used.
g. Connect the drain tube to the valve block connector
(item 6).
h. Connect the FILTRAX sample line to the bottom inlet on the
overflow vessel using the fittings (item 7).
3. Install the second sc analyzer (Analyzer 2):
a. Feed the sample line from Analyzer 1 through Analyzer 2
(item 4). Use Seal Plug #3 to secure.
b. Feed the drain tube through Analyzer 2 to an open drain
below. Use Seal Plug #3 to secure.
c. Use Seal Plug #3 to seal any unused openings.
d. Connect the drain tube to the T-fitting (item 5).
e. Connect the sample line from Analyzer 1 to the bottom inlet
on the overflow vessel using the fittings.
