manufacturer's website.
Section 2 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.
CAUTION
Fire hazard. This product is not designed for use with flammable samples.
The sampler collects liquid samples at specified intervals and keeps the samples in a refrigerated
cabinet. Use the sampler for a wide variety of aqueous sample applications and also with toxic
pollutants and suspended solids. Refer to Figure 1.
Lockable cabinet door
Push the round button in the center of the latch to open the door. Flip the latch to close the door tight.
Two keys are supplied for the door lock. Over time, it may be necessary to tighten the adjustment
screw on the door latch.
Controller compartment heater
The controller compartment heater is a factory-installed option. The heater prevents liquid from
freezing in the tubing, extends the life of the tubing and pump components and prevents the
collection of ice and snow on the cover.

4.3 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.
4.4 Intended use
The All Weather Refrigerated Sampler (AWRS) is intended for use by individuals who collect water
samples in locations where temperature control is necessary for sample preservation. The AWRS
does not treat or alter water.

4.5 Product components
WARNING
Fire hazard. This product contains a flammable refrigerant. Do not damage or puncture the
refrigeration circuit.
WARNING
Personal injury hazard. Instruments or components are heavy. Use assistance to install or move.
The instrument weighs a maximum of 86 kg (190 lb). Do not try to unpack or move the instrument
without sufficient equipment and people to do it safely. Use correct lifting procedures to prevent
injury. Make sure that all used equipment is rated for the load, for example, a hand truck must be
rated for a minimum of 90 kg (198 lb). Do not move the sampler when filled sample bottles are in the
refrigerated cabinet.
Make sure that all components have been received. Refer to Figure 3. If any items are missing or
damaged, contact the manufacturer or a sales representative immediately.
