14 Monitoring and Maintenance
NOTE
Check periodically whether amperage, visible on the Touch Screen, corresponds to the calculated
value for the expected Ag+ dosage.
14.1 Basic Maintenance
Once everything is properly set, handling is restricted to an occasional check of the milliamps (mA) setting
and the periodic cleaning of the electrode system.
Retighten all terminals once per year.
NOTE:
At 0.05 ppm (50 ppb) silver dose, each anode can treat approximately 4’000m 3 of water
At 0.02 ppm (20 ppb) silver dose, each anode can treat approximately 10’000m 3 of water
NOTE
Only use original spare parts which are listed in the attached spare parts list.
14.2 Checking the Effect
The silver concentration in the water may be analyzed regularly with appropriate measurement tools.
Samples to be taken at the sampling tap as well as at the final point of use (tap, bottling point, etc.)
Testing methods:
1. Silver ion test kits: simple to use however not very accurate. Useful just to test if there are actually
silver ions in the water
2. Colorimetric method or Ion Selective Electrode: This uses a handheld analyzer. Highly accurate. Can
measure down to 0.01ppm
3. Laboratory test using mass spectrometry: Very accurate
14.3 Cleaning the Electrode System
NOTE
Clean the electrode system in activator every 50 hours of operation and more often with harder
water.
This has to be done periodically. The frequency depends on the contents of minerals in the water. Generally,
cleaning is recommended after about 50 hours of operation.
To clean the electrode system, proceed as follows:
a)
Disconnect the power to the Electro-Katadyn-System (Control box and activator)
b) Close the inlet/drain valve to drain activator (switch from position A to B)
