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.

2.2 Certification

CAUTION

This equipment is not intended for use in residential environments and may not provide adequate protection to

radio reception in such environments.

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

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:

English 5

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.

2.3 Product overview

The Water Distribution Monitoring Panel sc (WDMP sc) is an assembly of instruments that monitor

the water quality in a distribution system. The instruments are mounted on a panel with the electrical

and plumbing connections installed. The instruments measure chlorine, conductivity, pH, ORP

(optional), turbidity, pressure and temperature. A controller sends the data to a communications

network for remote monitoring. Refer to Figure 1 for the WDMP sc with the CL17 chlorine analyzer or

Figure 2 for the WDMP sc with the CLF10 or CLT10 chlorine analyzer.

Section 3 Installation

D A N G E R

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

document.

3.1 Mechanical installation

WARNING

Personal injury hazard. Make sure that the wall mounting is able to hold 4 times the weight of the

equipment.

English 9

WARNING

Personal injury hazard. Instruments or components are heavy. Use assistance to install or move.

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.

Attach the panel on a flat, vertical wall surface in an indoor location away from direct sunlight. Install

the instrument in a location and position where the user can easily disconnect the instrument from

the power source. Refer to Figure 4 for product dimensions. Refer to Figure 5 to attach the panel to a

wall. Mounting hardware is supplied by the user.
