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

by looking through the unit where the right-hand cover panel has been removed.

Step 2: If the quartz is still dirty, use a scale remover such as CLR or Lime Away

and apply it to the inside of the quartz sleeve. Citric acid, available at a drug

store, can also be used.

Always flush with clean water afterwards.

Step 3: Once the quartz is clean, reassemble the unit (see below). Replace any

seals that appear to have been damaged.

Step 4: If the quartz is still not clean, it requires replacement. This is done by

removing the bottom quartz seal assembly.

Step 5: Remove the bottom Bracket (4) by undoing the four fasteners in an

alternating pattern (top left, bottom right, bottom left, then top right). The bottom

End Cap (5) will drop as the bracket is removed. Support the quartz sleeve as

you remove these two items.

Step 6: Remove the quartz sleeve by removing the top and bottom O rings (6).

Lift the quartz sleeve out of the unit.

Step 7: Install the new quartz sleeve into the unit and center it vertically. Be

careful not to chip the ends. Support the quartz for the next two actions.

Step 8

: Replace the top and bottom O rings (6), keeping the quartz centered

vertically in the unit.

Step 9: Replace the bottom End Cap (5) and bottom Bracket (4) by installing the

four fasteners in an alternating pattern (top left, bottom right, bottom left, then top

right)

(lock washers must be installed). Ensure that the welded elbow is at the

backside of the unit. Ensure that the bottom End Cap (5) sits centered in the

bottom Bracket (4).

Reassembling the Unit

Note that numbers in parentheses refer to Figure 4B.

Step 1: Replace the wiper assembly (12) carefully in the quartz sleeve. Turn the

wiper assembly clockwise (looking from the top) as it is being inserted into the

quartz – this will make the task easier and align the wiper blades properly. The
