Bladder Replacement - QED Sample Pro 3 Inch Instruction Manual

Bladder Replacement

1. Pull bladder down to remove it from the pump head.
2. Inspect the condition of the barb o-ring and replace it if necessary. Failure of this
o-ring could cause the water sample to be contaminated by pump drive air.
3. Install the new bladder by pushing it onto the pump head barb until the bladder fully
covers the barb, making sure the barb o-ring does not roll out of its groove.
NOTE: For reasons of contamination and leak integrity, these bladders are designed
for one-time use only. QED cannot be held responsible for cross contamination or
leakage failures if bladders are reused.
