6712FR Refrigerated Sampler
Section 8 Maintenance

8.4.2 Pump Tube Alarm The sampler tracks the pump counts in both the forward and
reverse cycles with a resettable counter. When the counter
reaches the default count of 1,000,000 or the count you have
e n t e r e d , t h e s a m p l e r d i s p l ay s a m e s s a g e, “ WA R N I N G !
REPLACE PUMP TUBE.” The message appears each time you
turn the sampler on or run a program until you reset the counter.
After replacing the pump tube (see page 8-9), reset the count to
zero so the sampler can begin tallying the pump counts for the
new tube. Replacing the pump tube does not reset the counter.
WARNING
Pump may actuate without warning. To avoid injury,
sampler must be off when pump housing cover is removed
for inspection or tubing replacement.
Experience may suggest a significantly different pump tube life.
You can change the alarm count to represent the pump tube life
for your application. The example below shows how to set the
alarm count and reset the pump counts.
