b. Turn off the water supply to the analyser.
c. Remove the wetside panel (optional). See paragraph 5.2.1, Wetside
Panel Removal and Replacement.
d. Using a 7/16-inch socket wrench, remove the two bolts (with
washers) attaching the occlusion ring to the panel. Lift off the
occlusion ring. Some residue from the tube units accumulates on
the ring during usage. This is normal.
5.2.2.2 Replacement
The occlusion ring may be difficult to reinstall if the following procedure is
not followed. Do not use excessive force. Use care not to pinch the tube units
(installed on the pump rollers) when installing the occlusion ring. Before
reinstalling the occlusion ring, check that the pump tube units are properly
seated in the roller grooves and in the tube retainer grooves. See paragraph
5.2.4, Pump Tubing Units Replacement.
1. Place the occlusion ring loosely in place over the tube units, but
do not attempt to clamp the occlusion ring in place yet.
2. Hold the ring in place with one hand and slide a bolt, with washer, into
the lower mounting hole in the ring until it bottoms against the casting.
3. Gently squeeze the ring against the tubing while pushing the bolt
into place. The bolt will drop (about ¼ inch) into place when the
ring is properly located.
4. Tighten this first bolt a few turns, so that the occlusion ring will
pivot on the bolt.
5. Slide the second bolt (and washer) into its mounting hole in the ring.
6. Firmly squeeze the ring against the pump rotor (squeeze near the
second bolt) to obtain leverage against the pivot bolt until the
second bolt drops into place. Finger tighten bolts until occlusion
ring is flat against panel.
7. Tighten bottom bolt 1/4 turn, then tighten top bolt 1/4 turn.
5.2.3 Pump rotor, rollers and thrust washer removal and replacement
The rotor is fastened to the motor shaft by a set screw requiring a 3/32-inch
Allen wrench for adjustment.
