Pump test and operation
1. Power on the pump: press and hold the power button
for three seconds. The pump will emit a series of audio
and visual indicators as it goes through the start-up
sequence. When the pump’s power status LED turns
green, it is ready for use.
2. Check the pump’s battery status indicator.
•
Solid green indicates the battery’s charge level is
between 50% and 100%.
•
Solid amber indicates the battery’s charge level is at
50% or less.
•
A blinking amber light with audible beep indicates a
critically low battery; the battery’s remaining charge will
operate* the pump for less than one hour.
3. Attach one end of the sample tubing to the pump inlet’s
nipple. Use a compatible water stop at the other end of
the sampling line.
*Operation at room temperature.
4. Use a thumb to block the end of the sampling line at
the water-stop opening. This should cause a pump-
fault alarm.
Remove the thumb from the water-stop opening. After
the alarm cycle completes, the pump should resume
normal operation.
Note: If a pump fault does not occur, check and correct for
cracks or other damage, debris, and proper installation in
these areas: the sampling line and its connections, the
pump's inlet cap and inlet barrel, and the dust filter-water
stop items at the end of the sampling line and inside the
pump inlet barrel.
Shutting down
To power off the pump, press and hold the pump power button . The audible indicator will sound five times before complete
shutdown.
