Power consumption is mostly determined by the ambient tem-
perature. Higher ambient temperatures will in turn create a
higher demand for power. A battery selection guide is provided in
Appendix F to help you determine the required battery capacity.
2.7 Attaching the Suction
Line
The suction line is the tubing from the sampling point to the
pump intake. The BLZZRD uses a
3
/
8
-inch ID suction line of
lengths 3 to 99 feet. Teledyne ISCO offers vinyl or PTFE suction
lines. The PTFE tubing has a polyethylene jacket to protect it
from kinks and abrasions.
Guidelines for Measuring and Cutting the Suction Line:
• Cut the line to the desired length but use the shortest
length feasible for the installation.
• Cut the line in 1 foot increments. For instance, 4 feet,
not 3
1
/
2
. If using metric units of measure, cut the line in
increments of 0.1 meter. Do not include the length of the
strainer in the measurement.
The vinyl line contains a very low parts-per-million level of
phenols. If phenol content affects your sample analysis, use the
PTFE suction line.
When installing the sampler, be sure the vertical distance
between the liquid level and the pump is as small as possible.
2.7.1 Attaching Suction Line
to Pump Tube
Attach the vinyl suction line to the pump tube with the
3
/
8
-inch
tubing coupler. First, screw the threaded end into the suction line
until the flat surface is flush against the suction line
(Figure 2-19). Then, push the other end of the coupler into the
end of the pump tube until the other flat surface is flush against
the tubing.
