Problem Cause Remedy
The pump is leaking. Sample Processor – A tub-
ing connection is leaking.
Check the tubing connections especially
between the distributor and the pump and
seal tightly.
Canister – There is too
much pressure on the
pump valve.
￭ Make sure that the canisters are not placed
on a higher level than the pump.
￭ Check the fill level of the canisters.
￭ Make sure that the canisters are not com-
pletely sealed (overpressure).
