Figure 4C
Use the 3/16” Hex wrench to remove the four fasteners in an alternating pattern
(top left, bottom right, bottom left, then top right). The bottom quartz seal
assembly does not require removal to clean the quartz, so leave it in place. This
will support the quartz sleeve during cleaning and simplify the overall process.
Step 5:
Remove the top quartz seal assembly (Figure 4C) by lifting it straight up.
The wires are bundled together using a tie wrap. If you require more room to lift
the top quartz seal assembly, cut the tie wrap to give you more freedom to lift the
assembly over the wiper shaft.
Step 6:
Remove the wiper assembly (21) by carefully lifting it up and out of the
quartz sleeve. Rotating it as you lift will help.
Caution: the wiper blades are
sharp, handle them with care.
Cleaning/Removing the Quartz Sleeve
Note that numbers in parentheses refer to Figure 4B.
Step 1:
Use a bottle cleaning brush with a long handle to scrub the inside of the
quartz sleeve. Scrub and flush it with water repeatedly to clean the quartz. Use a
squeeze bottle to apply water or solution to the quartz sleeve to keep the area
tidy.
Note: Keep the rest of the unit free from moisture.
Examine the quartz.
