4. Place another bucket under the unit and drain the unit completely (see Draining the Unit section).
Note that piping connections to the inlet and outlet ports will have to be removed in order to
disassemble the unit
’s stainless manifolds. Perform these disconnections now.
5. Open the UV Chamber as described in Accessing UV Chamber section. It may be necessary to have
the UV chamber door held open for this procedure.
6. Remove top plastic cover.
7. Disconnect wires to wiper motor, purge valve, and water temperature sensor (thermistor).
8. Remove the wiper motor by removing the two screws holding it to the plate.
9. Remove the motor mounting plate from the top manifold by removing the two screws and nuts.
Removing this plate will allow top manifold to come free from the wire bundle.
CAUTION! Do not damage sealing surfaces of manifolds or wiper shaft adapter - handle these parts with care
to prevent water leaks. The wiper assembly must also be handled with care to prevent damage to cleaning
edges. The wiper blades are sharp, handle them with care.

10. Remove the retaining ring (E-ring) holding the wiper shaft.
11. Use the 7/16
” (11mm) wrench or nut driver to remove the four nuts of the top manifold in an
alternating pattern (top left, bottom right, bottom left, then top right). The bottom manifold does
not require removal to clean the quartz sleeve, so leave it in place. This will support the quartz
sleeve during cleaning and simplify the overall process.
12. Press down on the wiper shaft and remove the top manifold (Figure 7.6) by lifting it straight up to
disengage the wiper shaft. The shaft adapter should remain on the top of the wiper shaft. Note the
orientation of the slot to the wiper blades
– the slot is aligned to the wiper blades.
13. Remove the wiper assembly by carefully lifting it up and out of the quartz sleeve. Rotating it
counter-clockwise as you lift will help. Prevent the shaft adapter from falling off the wiper assembly.
Note that the shaft adapter sits on the top end of the wiper shaft - the top end of the shaft has a
hole, the bottom end of the shaft does not.
