4. Operation
4.1 Preparation for Operation
1. Ensure that the unit is installed properly according to “3 Installation”.
2. Remove the lid of the overflow tank.
3. Remove the detector if the unit is already set to the measuring tank.
CAUTION
When removing from the measuring tank, put the detector on a flat surface to prevent it from
falling. It is recommendable to put the detector on the calibration tank for safe and easy handling.
4. 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.
6. 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 2 upper notches of the inner tank of measuring
tank and is discharged from the drain outlet.
Inner tank of measuring tank
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
detector.
9. Make sure that the cables of detector and converter are securely connected.
10. Set the switches of control panel as follows:
