Electro-Chemical Devices (ECD) CA6 Hardness Analyzer - Manual (Page 16)

1.1.4 Sample Stream
Take appropriate precautions to avoid direct contact with sample stream. It is the responsibility of the
user to collect all the information and take all the precautions regarding physical, chemical, radiation
and/or biological hazards and dangers coming from sample stream and/or sample vapors. It is also
responsibility of the user to collect all the information and potential hazards regarding the chemical and
physical compatibility of sample stream with the analyzer materials.
Table 1-2: List of materials used in the Model CA-6 Analyzer
Pump tubing Silicon or Norprene®
Fittings PP
Connection tubing Norprene® / Silicon
Colorimetric cell Quartz Glass
Micro peristaltic Pump Norprene® / PP
Mixing membrane pump PP / EPDM
Pinch valve Norprene® / Silicon tubing
1.1.5 Waste disposal of the liquid reagents for the colorimetric reaction
The liquid from the drain of the colorimetric cell may need to be collected in a separate canister. For
guidelines on disposal consult the requirements of the Local Authority for chemical waste regulation.
Arrange removal by a Disposal Company.
1.1.6 Analyzer General Hazards
1.1.6.1 Electrical precautions and hazards
Power to the CA-6 Analyzer must be routed through an ON/OFF power switch.
Mind the electrical shock and/or electrocution labels placed on the analyzer.
All electrical devices powered by 110/220 VAC present the hazard of electrical shock or electrocution.
The analyzer enclosure is equipped with a door that requires a special key for opening to protect all the
personnel involved in analyzer use and maintenance.
Only Qualified Service Personnel should have access to the key that opens the analyzer.
Before servicing the analyzer or any parts that are electrically powered, turn off the power to avoid the
risk of electrocution.
Inside the analyzer’s lower level, the electrical protection is IP2X. Analyzer’s enclosure is IP54.
Protection against electrical shock is guaranteed by the grounding of all isolated metal surfaces
.
Grounding terminal/screw is located inside the electrical enclosure, in Upper Left position.
It is the user’s responsibility to periodically check the efficacy of analyzer’s electrical ground.
In case of loss of power, the analyzer stops and automatically restarts as soon as power is returned.
