4. Check and clean O-rings in metering chamber cover. Replace if damaged,
worn or brittle.
5. Clean metering chamber using mild detergent.
Do not use any cleaner which may be harmful to the clear
acrylic (for example, petrochemical solvents, as noted
above). Do not use abrasives or “scouring” compounds.
6. For composite systems, check discharge tubing for wear and replace as
necessary.
7. Check pinch valve to ensure free movement.
8. If possible, run sampler through several sampling sequences in clean
water.
9.1.2 Internal Battery (when included)
1. Charge battery to full capacity when being stored for long periods and
disconnect fuse at battery.
2. Recharge battery to full capacity before being deployed.
3. Monitor battery voltage and recharge or swap out, at or before, 11.6 Vdc.
9.1.3 Intake Hose
1. Check for any obstructions at intake end and clean.
2. Inspect for breaks, cracks, or any point where leakage may be suspected by
submerging in a bucket of water and run through a complete sampling
cycle. Watch for air bubbles during the purge cycle.
3. Clean by completing several sampling sequences using mild detergent.
Do not use any cleaner that may be harmful to the intake
hose material.
9.1.4 Testing System Vacuum
Using a pressure / vacuum ga
u
ge, take a reading to ensure system has no
leaks. Optimal pressure is above 28 psi. Optimal vacuum should be 12 mm
Hg or higher. If the system is not performing at its peak, try the following:
1. Check intake hose for leaks/kinks.
2. Check discharge tube, ensure it has no leaks and is in good shape.
3. Check all fittings to ensure they are tight.
4. Make sure when tightening and loosening the brass gland nuts on the top
