4.1.3 Compliance and 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:
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.

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.
CAUTION
Fire hazard. This product is not designed for use with flammable liquids.
The portable sampler collects liquid samples at specified intervals and keeps the samples in bottles.
Use the sampler for a wide variety of aqueous sample applications and also with toxic pollutants and
suspended solids. Set up the sampler with different retainers or bottles. Refer to Figure 1.

Section 5 Installation
D A N G E R
Multiple hazards. Only qualified personnel must conduct the tasks described in this
section of the document.
5.1 Confined space precautions
D A N G E R
Explosion hazard. Training in pre-entry testing, ventilation, entry procedures,
evacuation/rescue procedures and safety work practices is necessary before entering
confined spaces.
The information that follows is supplied to help users understand the dangers and risks that are
associated with entry into confined spaces.
On April 15, 1993, OSHA's final ruling on CFR 1910.146, Permit Required Confined Spaces, became
law. This standard directly affects more than 250,000 industrial sites in the United States and was
created to protect the health and safety of workers in confined spaces.
Definition of a confined space:
A confined space is any location or enclosure that has (or has the immediate potential for) one or
more of the following conditions:
• An atmosphere with an oxygen concentration that is less than 19.5% or more than 23.5% and/or a
hydrogen sulfide (H2S) concentration that is more than 10 ppm.
• An atmosphere that can be flammable or explosive due to gases, vapors, mists, dusts or fibers.
• Toxic materials which upon contact or inhalation can cause injury, impairment of health or death.
Confined spaces are not designed for human occupancy. Confined spaces have a restricted entry
and contain known or potential hazards. Examples of confined spaces include manholes, stacks,
pipes, vats, switch vaults and other similar locations.
Standard safety procedures must always be obeyed before entry into confined spaces and/or
locations where hazardous gases, vapors, mists, dusts or fibers can be present. Before entry into a
confined space, find and read all procedures that are related to confined space entry.
5.2 Site installation guidelines
D A N G E R
Explosion hazard. The instrument is not approved for installation in hazardous locations.
This instrument is rated for an altitude of 2000 m (6562 ft) maximum. Although the use of this
equipment above the 2000 m altitude does not show any substantial safety concern, the
manufacturer recommends that users with concerns contact technical support.
Refer to the guidelines that follow for the site location evaluation.
• Obey all the safety precautions if the sampler is installed in a confined space. Refer to Confined
space precautions on page 10.
• Make sure that the temperature at the location is in the specification range. Refer to Specifications
on page 3.
• Install the sampler on a level surface or hang the sampler with the suspension harness, the
support bracket or the spanner bar. Refer to Install the sampler in a manhole on page 11 and to
the applicable installation documentation.
• Install the sampler as near the sample source as possible. Refer to Plumb the sampler
on page 13.
