Referring to Fig. 8.1:
1. Unlock catch
A, use handle B to slide the analytical
section forward and lock it into place using catch
A.
2. Release the pump tube clips on the downstream side to
prevent back-siphoning of reagents (and possible
contamination of solutions in the bottles) when platen C
is unlatched.
3. Using a screwdriver, remove capstan screw D and
washer E,
4. Remove pump end plate F (pull off squarely), ensuring
that the shaft-to-bearing adaptor is not lost.
5. Unlatch and rotate each platen C, to access the pump
tubing. Slide the platens off the pivot pin.
6. Unlatch the other side of the pump tubing G and discard
the tubing.
7. Slide off and discard each capstan H.
8. Replace each capstan. Ensure the capstans are aligned to
maximize mixing effectiveness.
9. If not already fitted, clip cover I to the outer capstan.
10. Clip the new tubing into place. Ensure the correct tubing is
used for each pump and the seals are in place:
Wet the mating surfaces with demineralized water and
squeeze between the two points shown below to ensure
that tubing clips into place correctly:
11. Ensure the tubing is aligned correctly over the rollers.
12. Refit the platens
C and pump end plate F.
13. Refit washer
E and capstan screw D.
Tighten screw D and clip each platen C into place:
14. Unlock the analytical section and slide it back into the
normal operation position. Lock the analytical section into
