Certification

Canadian Radio Interference-Causing Equipment Regulation, IECS-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:

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.

Class 1 laser

This symbol indicates that the instrument is a Class

1 LASER product.

This product complies with IEC/EN 60825-1:2007 and 21 CFR 1040.10 except for deviations

pursuant to Laser Notice No. 50, dated June 24, 2007. FDA accession number: 8921784-11.

This product contains a laser that is not user-serviceable.

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.

D A N G E R

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

The 2200 PCX particle counter is used for drinking water applications. The 2200 PCX does not have

data storage capability. The instrument uses a particle counting sensor with a laser-diode. The

instrument converts analog signals from other devices and send those output values through Modbus

communications. The instrument is used with the Vista software to select the size range, count

period and flow rate. Complete data collection with Hach UDG or Vista software. Refer to the

software documentation for more information. Refer to Figure 1.

Installation

WARNING

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

document.

Installation guidelines

Install the instrument:

• As near the sample source as possible to decrease analysis delay

• In a clean, dry, well ventilated and temperature controlled location

• In a location with minimum vibrations that has no direct exposure to sunlight

• In an environmental enclosure that supplies protection from precipitation and direct sunlight, good

ventilation and temperature control if installed outdoors

• In a location where the power switch and power cord are visible and easily accessible

• In a location where there is sufficient clearance around it to make plumbing and electrical

connections

Mechanical installation

Attach the instrument to the wall

WARNING

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

equipment.
