Certification

Canadian Radio Interference-Causing Equipment Regulation, IECS-003, Class A:

English 5

Supporting test records reside with the manufacturer.

This Class A digital apparatus meets all requirements of the Canadian Interference-Causing

Equipment Regulations.

Cet appareil numérique de classe A répond à toutes les exigences de la réglementation canadienne

sur les équipements provoquant des interférences.

FCC Part 15, Class "A" Limits

Supporting test records reside with the manufacturer. The device complies with Part 15 of the FCC

Rules. Operation is subject to the following conditions:

1. The equipment may not cause harmful interference.

2. The equipment must accept any interference received, including interference that may cause

undesired operation.

Changes or modifications to this equipment not expressly approved by the party responsible for

compliance could void the user's authority to operate the equipment. This equipment has been tested

and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC rules.

These limits are designed to provide reasonable protection against harmful interference when the

equipment is operated in a commercial environment. This equipment generates, uses and can

radiate radio frequency energy and, if not installed and used in accordance with the instruction

manual, may cause harmful interference to radio communications. Operation of this equipment in a

residential area is likely to cause harmful interference, in which case the user will be required to

correct the interference at their expense. The following techniques can be used to reduce

interference problems:

1. Disconnect the equipment from its power source to verify that it is or is not the source of the

interference.

2. If the equipment is connected to the same outlet as the device experiencing interference, connect

the equipment to a different outlet.

3. Move the equipment away from the device receiving the interference.

4. Reposition the receiving antenna for the device receiving the interference.

5. Try combinations of the above.

Product overview

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.

The analyzer measures total ammonia and monochloramine in drinking water and calculates free

ammonia concentration. The chemical analysis uses a modified phenate method to measure

monochloramine values by colorimetry. An excess of hypochlorite at the correct pH generates total

ammonia values measured by colorimetry. Then, the analyzer calculates the free ammonia values

out of the difference between the measured parameters.

Refer to Figure 1 for the analyzer overview. The doors can be easily removed for better access.

Refer to Figure 2. Make sure that the doors are installed, closed and securely latched to keep the

enclosure environmental rating.

Installation

WARNING

Multiple hazards. Only qualified personnel must conduct the tasks described in this section of the

document.

Mechanical installation

D A N G E R

Risk of injury or death. Make sure that the wall mounting is able to hold 4 times the weight of the

equipment.

WARNING

Personal injury hazard.

Instruments or components are heavy. Use assistance to install or move.

The object is heavy. Make sure that the instrument is securely attached to a wall, table or floor for a

safe operation.

This instrument is rated for an altitude of 2000 m (6562 ft) maximum. Use of this instrument at an

altitude higher than 2000 m can slightly increase the potential for the electrical insulation to break

down, which can result in an electric shock hazard. The manufacturer recommends that users with

concerns contact technical support.

Install the analyzer indoors, in a non-hazardous environment. Refer to the supplied mounting

documentation.

Plumbing

D A N G E R

Fire hazard. This product is not designed for use with flammable liquids.

N O T I C E

Do not install reagents until all plumbing is complete.

Make sure to use the specified tubing size.

Sample line guidelines

Select a good, representative sampling point for the best instrument performance. The sample must

be representative of the entire system.

To prevent erratic readings:

• Collect samples from locations that are sufficiently distant from points of chemical additions to the

process stream.

• Make sure that the samples are sufficiently mixed.

• Make sure that all chemical reactions are complete.

Connect the sample stream

Install each sample line into the center of a larger process pipe to minimize interference from air

bubbles or bottom sediment. Figure 3 shows examples of good and bad installation.

Keep the sample lines as short as possible to prevent the accumulation of bottom sediment. The

sediment can absorb some of the analyte from the sample and cause low readings. The sediment

can later release the analyte and cause high readings. This exchange with the sediment also causes

a delayed response when the analyte concentration in the sample increases or decreases.

Plumbing access ports

Make plumbing connections through the plumbing access ports. Refer to Figure 4. To keep the

enclosure rating, make sure that plugs are installed in the plumbing ports that are not used.

CAUTION

Explosion hazard. Use only the supplied regulator from the manufacturer.

English 9

CAUTION

Chemical exposure hazard. Dispose of chemicals and wastes in accordance with local, regional and

national regulations.

N O T I C E

Do not connect the drain lines to other lines because backpressure or damage to the analyzer can occur. Make

sure that the drain lines are open to air.

N O T I C E

To prevent backpressure and damage to the analyzer, make sure that the analyzer is higher than the facility

drain(s) used and that the drain line has a constant downward slope.

Use the supplied tubing (6 mm), shut-off valve, Y-strainer with filter and pressure regulator to plumb

the drain and the sample to the analyzer. Refer to Figure 5 and Figure 6. The sample line tubing that

goes into the plumbing access ports must be 6 mm. Tubing of 1/4 in. can be used for the sample line

up to the valve or to the y-strainer, but not into the plumbing access ports of the analyzer. For correct

drainage, install the drain lines at least with a 1-inch decrease in height per 1 foot of tubing length.
