9.4.7 Pump Tubing Replacement
Tubing life depends on instrument usage. The buffer and calibrator pump tubing should be replaced at least every 6
months or 1000 hours sample ready.
NOTE: The buffer pump tubing and calibrator pump tubing each require a different type of grease. It is important to apply
the correct grease to each type of tubing.
9.4.7.1 Buffer Valve Tubing (2950 only)
Remove the old tubing from the valves by grasping each tube on both sides of the valve and pulling it straight out. To
ensure correct operation and prevent premature tubing failure, install the new valve tubing as follows:
1. Connect the end of the clear section of buffer valve tubing to the inner port of the sipper
pump.
2. Insert the short section of valve tubing close to the first Y (near the clear section) into the
inner channel of the bottom valve. Hold the tubing on both sides of the valve and push it
straight into the valve channel until it snaps in. Try not to stretch the tubing.
3. From the Service screen Pumps tab, touch the [OFF] button under Bottom Valve to turn
ON the Bottom Valve.
4. With the bottom valve ON, insert the long section of valve tubing close to the first Y (near
the clear section) into the outer channel of the bottom valve. Hold the tubing on both
sides of the valve and push it straight into the valve channel until it snaps in.
5. From the Service screen Pumps tab, touch the [ON] button under Bottom Valve to turn
OFF the Bottom Valve.
6. Insert the one section of valve tubing close to the second Y into the inner channel of the top valve. Hold the tubing
on both sides of the valve and push it straight into the valve channel until it snaps in.
7. From the Service screen Pumps tab, touch the [OFF] button under Top Valve to turn ON the Top Valve.
8. Insert the other section of valve tubing close to the second Y into the outer channel of the top valve. Hold the
tubing on both sides of the valve and push it straight into the valve channel until it snaps in.
9. From the Service screen Pumps tab, touch the [ON] button under Top Valve to turn OFF the Top Valve.
10. Verify that all valve tubing is inserted fully into the channels of both valves.
