6.10. Tube Replacement
6.10.1 Replace the Pump Tubes
Overview
A-96.250.571 / 050517
The pump tube [D] of the peristaltic pump is exposed to a minimal
wear.
It is therefore recommended to exchange the pump tube annually.
CAUTION
Pollution of reagents possible.
If the occlusion frames are opened during operation, already
mixed reagents will flow back into the reagent canisters and pol-
lute the reagents.
Never open the occlusion frames if the instrument is in opera-
tion.
Proceed according to
43
before opening the occlusion frames.

Questions and answers
Using the AMI Codes-II, there is Chlorine in the system, yet the system reads 0.00. Reseted, still no feedback. what could be the problem.
If the Swann AMI Codes-II system reads 0.00 for chlorine despite chlorine being present, possible issues could include:
1. Reagent Issues – The required reagents (OXYCON ON-LINE DPD, buffer solutions, etc.) might be depleted, expired, or improperly mixed.
2. Clogged or Dirty Components – The sample inlet, inlet filter, or flow regulating valve might be clogged, preventing proper water flow.
3. Calibration or Sensor Issues – The system may need recalibration, or the sensor might be faulty or improperly installed.
4. Power or Electrical Issues – The instrument may not be receiving proper power, or there could be an electrical fault affecting measurement.
5. Interference from Additives – Certain water additives like corrosion inhibitors or cyanuric acid might interfere with chlorine detection.
Checking reagent levels, cleaning components, recalibrating, and verifying power and water flow can help identify and resolve the issue.
