6700 Portable Sampler User Manual - Isco

Note
If using a power pack with the
6700, Isco recommends you use
the new 913 or 923 power pack.
Older model power packs may
not provide sufficient power.
Refer to the Isco Power Products
Guide shipped with your sampler
for more information on Isco’s
power sources.

About Suction Lines
Thevinyllinecontainsavery low parts-per-million level of
phenols. If phenol content
affects your sample analysis,
use the Teflon suction line.
Occasionally, your sampling
application may suggest a
nonstandard line. For best
sampling results, however, use
the standard suction line
available from Isco.
When installing the sampler,
be sure the vertical distance
between the liquid level and
the pump is as small as
possible.

INSTALLING A POWER SOURCE
The 6700 Sampler requires 12-volt DC power. Power sources
available from Isco are listed below.
946 Lead Acid Battery
934 Nickel Cadmium Battery
913 High Capacity Power Pack (120 volts AC, 50/60 Hz)
923 High Capacity Power Pack (240 volts AC, 50/60 Hz)
914 Battery Backed Power Pack (120 volts AC, 50/60 Hz)
924 Battery Backed Power Pack (240 volts AC, 50/60 Hz)
948 45 Amp Hr Battery
To install the smaller batteries or power packs on the sampler:
1. Place the power source in the sampler’s battery recess.
2. Secure the power source with the black rubber draw-catches.
3. Attach the power-source cable to the power-source connector
on the controller.
Connecting an External 12-Volt DC Source
You can also power the sampler with an external 12-volt DC
source, such as an automotive battery. Connect the sampler to
the battery with the External 12-Volt DC Power Cable.
Be sure to attach the positive and negative clips to the correct
battery terminals. If polarity is reversed, the sampler may be
permanently damaged.
SUCTION LINE
The suction line is the tubing from the sampling point to the pump
intake. The 6700 uses a 3 /8-inch ID suction line of lengths 3 to 99
feet. Isco offers vinyl or Teflon ® suction lines. The Teflon ® 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.
Attaching Suction Line to Pump Tube
Attach the vinyl suction line to the pump tube with the tube coupling.
Use the black clamp for the pump tube and the white
clamp for the suction line. Attach the line and tube to the coupling
by pushing them onto each end of the coupling. Then
tighten the clamps by squeezing the finger pads together. Loosen
a clamp by twisting it until its teeth disengage.
Attach the Teflon ® suction line to the pump tube by inserting the
line into the tube and secure with a suitable clamp.
