BLZZRD ™ Portable Refrigerated Sampler
Section 2 Installation/Preparation
2-3
• Support – The surface must be able to support the
BLZZRD at full capacity. This weight would include the
sampler, the full sample bottles, and the battery (if
used).
• Ventilation – The sampler requires at least 1 foot (0.3 m)
of air space around the refrigeration components. Inade-
quate ventilation will reduce the cooling capacity and
significantly increase power consumption.
• Environmental – The sampler is designed for outdoor
use. However, you should avoid installing the sampler in
locations where its components are subject to chemical
attack. Also, prolonged exposure to direct sunlight will
eventually damage the exterior. If the sampler is subject
to chemical attack or prolonged UV exposure, consider
using a protective enclosure. Keep in mind that
positioning the sampler in direct sunlight will also
increase power consumption, a factor worth considering
when using battery power.
CAUTION
Do not install the BLZZRD in corrosive atmospheres. Exposure
to hydrogen sulfide gas, marine atmospheres, or salt spray will
damage the refrigeration system.
• Avoid submersion – Although the controller will resist
damage (rated NEMA 4x, 6), the refrigerator system
and bottle compartment cannot prevent the liquid from
entering. Liquid entering the refrigerated system will
damage the cooling system; liquid entering the bottle
compartment will contaminate the collected samples.
• Accessibility – The sampler must be installed in a
location where it can be recovered easily without tipping
or difficult maneuvering.
• Security – The location may need to provide some degree
of security to prevent tampering or vandalism. You can
read more about securing the sampler in section 2.11.
Place the sampler on a flat, horizontal surface. Placing the sampler
on an incline may cause the sample to miss the bottle mouth. When
installing the sampler, be sure the vertical distance between the
level of the liquid and the pump is as small as possible.
Note
When using the BLZZRD with a 750 or 710 module, transmit-
ters such as cell phones or walkie talkies must not be operated
within 3 meters of the sampler. If water level readings are fluc-
tuating due to TV/radio station transmitter towers in the area,
the sampler must be relocated.
