CHANGING PERISTALTIC PUMP TUBING
It is recommended that the peristaltic pump tubes be changed on
a regular basis depending on sampling period and operating
time.
For a 5 minutes sample interval and continuous operation,
changing of the tubes every month is recommended. For best
results however, change the tubings every time the reagents are
replaced.
Note:
Rubber gloves and eye protection must be worn while
handling reagent tubing to prevent contact with reagent
chemicals. Read MSDS documents before proceeding.
Grasp the plastic collar of one pump tube and pull the fitting
away from the pump toward the front of the case until it clears
the retaining indentation.
Then move the fitting sideways from the pump until the tube
clears the slot.
Release the tube and fitting. The fitting on the other end of the
pump tube may now be easily removed from the pump body.
Remove the reagent tubing from one end of the pump tube
fitting and pull the pump tube from behind the pump rollers.
Replace the pump tube with a new one and reassemble in
reverse order. Repeat for the other pump tube.
