4.1.4 Chemical and biological safety
D A N G E R
Chemical or biological hazards. If this instrument is used to monitor a treatment process and/or
chemical feed system for which there are regulatory limits and monitoring requirements related to
public health, public safety, food or beverage manufacture or processing, it is the responsibility of the
user of this instrument to know and abide by any applicable regulation and to have sufficient and
appropriate mechanisms in place for compliance with applicable regulations in the event of
malfunction of the instrument.
4.1.5 Ozone precautions
CAUTION
Ozone inhalation hazard. This instrument produces ozone that is contained within the equipment,
specifically within the internal plumbing. The ozone could be released under fault conditions.
It is recommended to plumb the exhaust gas port to a fume hood or to the building exterior in
accordance with local, regional and national requirements.
Exposure to even low concentrations of ozone can damage delicate nasal, bronchial and pulmonary
membrane. In sufficient concentration, ozone can cause headaches, coughing, eye, nose and throat
irritation. Immediately, move the victim to uncontaminated air and seek first aid.
The type and harshness of symptoms are based on the concentration and exposure time (n). Ozone
poisoning includes one or more of the symptoms that follow.
• Irritation or burning of the eyes, nose or throat
• Lassitude
• Frontal headache
• Sensation of sub-sternal pressure
• Constriction or oppression
• Acid taste in mouth
• Asthma
In case of more severe ozone poisoning, the symptoms can include dyspnea, cough, choking
sensation, tachycardia, vertigo, lowering of blood pressure, cramping, chest pain, and generalized
body pain. Ozone can cause a pulmonary oedema one or more hours after exposure.

4.2 Intended use
The Hach EZ-series analyzers are intended for use by individuals who measure multiple water
quality parameters in samples from industrial and environmental applications. The Hach EZ-series
analyzers do not treat or alter water and are not used to control procedures.
4.3 Product overview
The Hach EZ-series analyzers are on-line analyzers that measure one or multiple parameters in
water samples from industrial and environmental applications. Refer to Figure 1.
The sample line moves the sample into the analyzer. The analyzer uses pumps, valves and syringes
to move the sample and reagents to the measuring cell on the analytics panel. When the
measurement cycle is complete, the analyzer discards the sample through the drain line. The
analysis results shows on the display of the data processing panel. The data processing panel
controls and configures the analyzer. The data processing panel saves the analyzer data (i.e.,
trends , alarms, analysis results and data log files).
A set of reagent bottles is supplied with the analyzer to hold the reagent and solutions. Sample
preconditioning could be necessary based on the analysis technology. Optional sample
preconditioning panels are available for the sample line.
There are different analyzer series available with different measurement technology and measured
parameters:
• EZ 1000 series—On-line colorimetric analyzers for general water analysis (chemical parameters)
and nutrient analysis (i.e., nitrate, phosphate, ammonia)
• EZ 2000 series—On-line colorimetric analyzers with digestion for general water analysis (chemical
parameters) and nutrient analysis (i.e., nitrate, phosphate, ammonia)
• EZ 3000 series—On-line ion-selective (ISE) analyzers for general water analysis
• EZ 4000 series—On-line titrimetric analyzers for general water analysis (chemical parameters)
• EZ 5000 series—Multiparametric on-line titrimetric analyzers for general water analysis (chemical
parameters)
• EZ 6000 series—On-line voltammetry analyzers for heavy/trace metal analysis (e.g., Ag, As, Cr,
Hg, Pb, Se)
• EZ 7x00 serires—On-line analyzers for industrial applications (e.g, COD, TOC, Total Nitrogen,
Total Phosphorus, volatile fatty acids FOS/TAC, influent toxicity, international bitternes units,
Adenosine Triphospahte)
The EZ-analyzer has different options such as: Sample detection, level detection for reagent bottles,
remote Start/Stop, auto-validation, auto-calibration, auto-cleaning, RS232 and Modbus.

Multiple hazards. Only qualified personnel must conduct the tasks described in this section of the
document.
5.1 Installation guidelines
WARNING
Fire hazard. The user is responsible to make sure that sufficient precautions are taken when the
equipment is used with methods that use flammable liquids. Make sure to obey correct user
precautions and safety protocols. This includes, but is not limited to, spill and leak controls, proper
ventilation, no unattended use, and that the instrument is never left unattended while power is
applied.
CAUTION
Chemical exposure hazard. Obey laboratory safety procedures and wear all of the personal protective
equipment appropriate to the chemicals that are handled. Refer to the current safety data sheets
(MSDS/SDS) for safety protocols.
