Glacier Transportable Sampler - Isco

Glacier Transportable Sampler
Section 2 Installation
CAUTION
Never use a DC extension cable without first consulting with a
Teledyne Isco Service Technician. They will advise you of the
proper wire gauge for the length you require.
The refrigerator compressor is equipped with a battery controller
that will cut out to protect the compressor and the battery when
the voltage drops to 10.4–11.3 VDC. The controller will cut in at
11.7–12.5 VDC.
CAUTION
Never charge the battery while connected to the Glacier.
Over-voltages could damage the electronics.
Note
The refrigerator housing has a High/Low power switch
mounted near the DC input power connector. This High/Low
switch is unused. The switch must remain in the Low position
for normal operation.

Recommendations
2.8 Connect a Suction
Line and Strainer
Before each sampling program, the battery should be exchanged
with a fully-charged battery.
Power consumption is mostly determined by the ambient temperature.
Higher ambient temperatures will in turn create a higher
demand for power. A battery selection guide is provided in
Appendix D to help you determine the required battery capacity.
The suction line carries the liquid from the sampling point to the
Glacier pump tubing. The Glacier is designed to use:
• 1 /4-inch (6-mm) I.D. Vinyl tubing
• 3 /8-inch (9-mm) I.D. Vinyl tubing
• 3 /8-inch (9-mm) I.D. PTFE tubing with a protective
polyethylene jacket
Note
Selecting 1 /4-inch (6-mm) suction line disables the Bottle Full
detection.
Note
The vinyl suction line contains a very low ppm (parts per million)
level of phenols. If this affects your samples, use the
PTFE suction line.
The strainer reduces the possibility of debris plugging the
suction line. Three types are available:
• 3 /8-inch standard weighted polypropylene strainer
