Parts Required Part number
Peristaltic Tube Set MT01-0500
Tools Required

Procedure
Place a small container or rags under each of the tubing connections when disconnecting, small amounts of detergent
and alcohol will be lost during replacement of the pump tube.
The two alcohol pumps are located to the left of, and just behind the 0.2 micron filter housing which is in the center of
the machine. The detergent pumps are located to the right of and just behind the 0.2 micron filter housing. The top
pumps on both sides supply the “A” side of the machine and the bottom pumps supply the “B” side. Replace the tubing
one pump at a time to avoid confusion with the plumbing. To assist with reassembly, label each tube before
disconnection.
Identify and disconnect the inlet and outlet tubing from the pump you are servicing.
Identify and remove four screws from pump covers. Refer to Figure 41.
Remove cover to expose pump tube. Remove the tubing from the pump head by pulling the tube out of the support
recess, rotate the pinch roller by hand while gently pulling the tube, keep rotating and pulling until the tube is
completely released.
Remove the new tube set from the packaging.
Position the new tube over the pump head so that the inlet and outlet are of equal length.
Position the pinch rollers as in figure 42.
Lay the new tube in the recess and rotate the roller as you feed the tube into place until the tube is completely
installed. Refer to figure 43.
Replace the cover using the screws that were removed earlier.
Re-connect the inlet and outlet tubes that were disconnected during removal.
Priming of the pumps will be performed in the final check procedure.
