Remove the lid of the overflow tank.
3.
Remove the analyzer unit if the unit is already set to the measuring tank.
Note
When removing from the measuring tank, put the analyzer unit on a flat surface to prevent it from
falling. It is recommendable to put the analyzer unit on the calibration tank for safe and easy handling.

Operate the valves as instructed in the flow sheet and dimensional outline drawing:
V-1 and V-4: close all (CLOSE)
V-2 and V-3: open all (OPEN)
5.
Supply 2 L/min to 20 L/min of sample water from the underwater pump or the
header.

Open valve (V-1) gradually until sample water runs out of the overflow outlet (1) of
overflow tank. If the sample water does not run out of the overflow outlet (1) even
when the valve (V-1) is fully opened, then close valve (V-2) gradually to adjust the
flow from the overflow outlet (1).
7.
Ensure that sample water overflows from the upper notches (2) of the inner tank of
measuring tank and is discharged from the drain outlet.
8.
When outlet flow from the overflow tank and the inner tank of measuring tank
reaches the designated volume and keeps running consistently, attach the lid of
the overflow tank and analyzer unit.
