3.6.4 Connecting Reagent and Calibration Solutions
1. Place the unopened reagent and calibration solution
containers in a suitable position no more than 1100 mm
(43.3 in.) from the analyzer’s bottom tray or on the optional
reagent tray (if fitted – see Section 3.4.3, page 12).
2. Referring to Fig. 3.11, hold the reagent level sensor by
clamp ring
A
and:
a. Using a dry, lint-free cloth, remove any foreign matter
from level sensor stem
B
.
b. Remove the reagent container cap and store in a
clean, safe place.
c. Insert the reagent level sensor into the reagent
container, ensuring that all connections are still in
place.
d. Check that the end of the level sensor is in close
proximity to the bottom of the reagent container. If
required, unscrew clamp ring
A
, adjust nut
C
to
position the sensor correctly, then secure with clamp
ring
A
.
e. Secure the reagent level sensor to the reagent
container with cap
D
.
f.
Remove the calibration solution container cap and
store in a clean, safe place.
g. Lower the sinker on the end of the calibration solution
line to the bottom of the calibration solution container.
h. Repeat steps 2a to 2e to connect the calibration
solution level sensor to the calibration solution
container.
Warning.
Reagents and calibration solutions may contain
hazardous chemicals. Ensure that safety information
is read and understood before handling the solutions.
Wear appropriate protective clothing when handling
reagent and calibration solutions.
Note.
Take care when installing the reagent and calibration
solution to prevent contamination. Keep the level sensors
dry and avoid handling the stems.
Note.
Step 2g is applicable only if the analyzer is
fitted with the standard calibration solution tubing
sinker.
Note.
Step 2h is applicable only if the analyzer is
fitted with the optional calibration solution level sensor.

Note.
When using the analyzer to measure ammonia
samples with concentrations typically above
300 ppm, it is strongly recommended that a mixer
assembly (part number AW621 045) is fitted to ensure
adequate mixing of the higher strength reagent
solution – see Fig. 3.13, page 21.
Refer to Appendix A, page 76 for further guidance on
reagent and standard solutions.
