ECD CA-6 - Analyzer Initial Start-Up; Sample and Drain Tubing Connections

6.0 ANALYZER INITIAL START-UP
 Open The Liquids Compartment
 Remove the block from the Drain Pinch Valve by
pressing the black button. Save for future use. It
removes compression from the drain tube when
the CA6 is not in use.
 Install the Fast Loop Reservoir(s) close to the right
side of the CA-6 Analyzer. Samples and Dilution
water must be drawn from atmospheric pressure.
6.1 Sample and Drain Tubing Connections
After double checking Sections 4.0 & 5.0, proceed as follows:
 Connect the overflow drain of the Fast-Loop Reservoir(s) to the drain with 12 mm OD tubing.
 Connect the sample feed line (or the outlet of the optional
filtering unit) to the bottom of the Fast-Loop Reservoir
previously installed on the right side of the analyzer.
 Connect the sample inlet tubing from the analyzer, Sample
#1, to the “Sample to Analyzer” port fitting on top of the
Fast-loop Reservoir. The John Guest fitting accepts 1/8” I.D.
flexible tubing (Tygon, Pharmed or Norprene are
recommended). The sample will now be taken from
atmospheric pressure by the sample peristaltic pump.
 Connect the reagents tubing (coming from the reagent
bottle) to the corresponding REAGENT port fitting (Reagent
1 to Port 1) using 1/16” I.D. flexible tubing (Tygon, Pharmed
or Norprene are recommended). The reagents will be
delivered to the optical cell by the internal reagent
peristaltic pumps. Note the maximum height of 15.75” (40 cm) between the bottom of the
bottle(s) and the bottom edge of the analyzer panel. Repeat for additional Reagents as required.
 Connect the analyzer drains (CELL and VENT DRAINS) to a waste line using 3/8” flexible tubing.
WARNING: the drain from the analyzer must
be at atmospheric pressure with no
restrictions. The drain line should be properly
sized to accommodate the overflow coming
from external fast-loop reservoir and the
gravity fed analyzed sample.
 Check sample level in the Fast-Loop Reservoir,
if used, and adjust the sample flow rate to
allow a continuous overflow to the drain line.
 Connect float valve switch from the Fast Flow
