3.2.13 Providing sample flow at the sample inlet
Ensure that the fluid circuit is completely closed and tight.
1.
Insert long cables into the cable passage under the IQ S
ENSOR
N
ET
module stack.
1.
Plug the sample feed tube into the connector for the sample feed on the
drinking water panel and secure it with a tube clamp.
CAUTION
Risk of injury in case of overpressure due to splashing
water.
Wear protective goggles when connecting the sample
feed to the drinking water plate (see section 2.4 Personal
protective equipment (PPE)).
2.
Slowly turn on the sample flow.
3.
In the presence of a turbidimeter (Turb PLUS 2000) in the liquid circuit
(see operating manual of the turbidimeter):
Pull the cell out of the cell shaft.
Check the cell for leaks with the lid screwed on.
4.
Check all tube connections of the drinking water panel for leaks.
5.
Check the flow rate on the flow indicator.
6.
If necessary:
Adjust the flow rate on the pressure reducer.
The sample stream contains air bubbles, especially after commis
-
sioning, which influence the measured turbidity value.
