Electro-Chemical Devices (ECD) CA6 Hardness Analyzer - Manual (Page 69)

9.0 MAINTENANCE
Basic maintenance on the CA-6 Analyzer requires refilling or replacing reagent containers and cleaning
the colorimetric cell on a regular basis.
In addition we advise that you perform an overall visual check of the wetted parts for any leakage. If any
leaks are detected, take immediate corrective action. Cleaning of the analyzer cabinet is best performed
using a soft, non-aggressive cleaner.
The use of a logbook for registering reagent refilling, corrective measures and performed scheduled
maintenance is strongly recommended.
Switch off the power to the analyzer prior to the performance of the basic maintenance work, the CA6
Analyzer cannot be operational during maintenance. Prior to any maintenance work, take into
consideration all necessary precautions regarding personal safety (protective clothing, safety glasses
etc.).
Always label and rinse all connected tubing with water prior to removal.
!
Caution
CA-6 Analyzer is based on colorimetric analysis methods, using chemical solutions.
Make sure proper safety precautions are taken (e.g. using safety gloves and glasses)
when handling chemical solutions.
