A.10 Option 6 plumbing and connections
Option 6 uses two sc analyzers with two FILTRAX (FILTRAX 1 and
FILTRAX 2). Samples from both FILTRAX are going into Analyzer 1
using the 2-parameter configuration. The heated drain hose
connects both sc analyzers. The waste from both analyzers is
discharged into a drain through the heated drain hose.
Refer to Figure 32 and the following instructions for Option 6:
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 32 , item 25). Use Seal Plug #1 to secure.
b. Feed the heated hose from FILTRAX 2 through the
analyzer (item 27). Use Seal Plug #1 to secure.
c. Feed the heated drain hose through the analyzer (item 28).
Use Seal Plug #1 to secure. Connect the heated drain
power connections. Refer to
section 3.5.5, page 27 .
d. Remove the pre-installed drain tube attached to the valve
block and remove the T-fitting from the drain tube. Retain
for reuse with Analyzer 2.
e. Connect the heated 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 20).
g. Connect the sample line from FILTRAX 2 to the bottom inlet
on Overflow Vessel 2 using the fittings (item 19).
h. Change the analyzer to the 2-parameter configuration.
Refer to Connect a 2-parameter option, page 66 .
i. Connect Sample Line 1 from the heated drain to Overflow
Vessel 1. Connect Sample Line 2 from the heated drain to
Overflow Vessel 2.
3. Install the second sc analyzer (Analyzer 2)
a. Feed the heated drain hose from Analyzer 1 through
Analyzer 2 (item 13). Use Seal Plug #1 to secure.
b. Feed the heated drain hose through the analyzer (item 8).
Use Seal Plug #1 to secure. Connect the heated drain
power connections. Refer to
section 3.5.5, page 27 .
c. Seal the remaining opening with Seal Plug #3.
d. Cut 25 mm from the drain tube that was removed from
Analyzer 1. Connect the 25 mm piece of tubing to the
T-fitting on Analyzer 2. Connect the other end of the tubing
to the T-fitting that was removed from Analyzer 1. Refer to
Figure 26, page 67 for T-fitting removal.
e. Connect the drain tube from Analyzer 1 and the drain tube
from Analyzer 2 to the T-fitting.
4. Connect Sample Line 1 from Analyzer 1 to Overflow Vessel 1
using the fittings (item 16). Connect Sample Line 2 from
Analyzer 1 to Overflow Vessel 2 using the fittings (item 17).
