2.4 Inspecting the Pump
Tube
The sampler is shipped from the factory with a new pump tube
installed. An inspection for first-time use is not necessary.
However, the pump tube should be inspected or replaced before
running all subsequent sample-collection programs.
If your sampling protocol mandates that you replace the pump
tube for each sampling program, refer to the replacement
instructions in section 9.4. Otherwise, the pump tube can remain
until one of the two following conditions are present:
•
The sampler controller displays a pump tube warning,
or
—
•
A pre-sampling program visual inspection identifies a
worn or damaged tube.
The pump tube must be replaced when the first of either con-
dition exists.
Note
The importance of regular tubing inspection and replacement
cannot be overstated. The key is to replace the tube before fail-
ure, not after. When a pump tube ruptures, grit and other abra-
sive debris can be driven into the pump shaft seal. Over time,
this abrasive material will degrade the pump seal, jeopardizing
the NEMA 4x 6 rating of the controller.
Failure to maintain the pump tube may result in permanent
damage to the sampler. Check the condition of the pump tube
regularly and if the tube shows signs of fatigue or wear,
replace it immediately. A properly maintained sampler will pro-
vide years of reliable service that is expected of a Teledyne
ISCO Sampler.
Section 9.4 of this manual describes the pump tube removal and
replacement steps. Afterwards, be sure to reset the pump counter
(section 9.3.2).
2.4.1 Pump Tube Warning
The sampler displays a pump tube warning at the recommended
replacement interval. The warning display will alternate with
the run screens, and is part of the
VIEW LOG
screens. Regardless
of the visual condition of the pump tube, it should be replaced as
soon as possible after the warning.
The warning appears after the controller reaches the factory set
value of 1,000,000 pump counts. This value will deliver approxi-
mately 500 samples of 200 ml each, using a
3
/
8
-inch by 10-foot
suction line at a 5-foot suction head. The pump tube replacement
interval of 1,000,000 pump counts should be sufficient for most
applications. If you are sampling abrasive liquids or liquids with
a high content of suspended solids, you may find that the pump
tube requires replacement more frequently.
2.4.2 Visual Inspection
The pump tube must be inspected before running each program.
Pump tube failures can prevent the sampler from collecting the
samples

or worse

may even damage the controller.
