7.8 Cleaning/Removing the Quartz Sleeve
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 sleeve. 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 sleeve.
2. If the quartz sleeve 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.
3. Once the quartz sleeve is clean, reassemble the unit (see Figure 7.8). Replace any seals that appear
to have been damaged.
4. If the quartz sleeve is still not clean, it requires replacement. This is done by removing the bottom
manifold (see Figure 7.7). Replacing a quartz sleeve is easier when the unit is placed on a horizontal
surface
– removing the unit from the wall to work on a bench is recommended, especially for the
UV-H Hallett 1000 models.

5. Remove the bottom plastic cover and then the bottom manifold by undoing the four nuts in an
alternating pattern (top left, bottom right, bottom left, then top right). Do not allow the Teflon
washer at the lower cavity of the bottom manifold to fall out
– the wiper shaft sits on this washer.
Support the quartz sleeve as you remove this item.
6. Remove the quartz sleeve by removing the top and bottom O rings and then the quartz centering
rings. Lift the quartz sleeve out of the unit.
7. Install the new quartz sleeve into the unit and center it vertically.
Be careful not to chip the ends.
Support the quartz sleeve for the next two actions.
8. Install the quartz centering rings (small tabs face outwards) and then the top and bottom O rings,
keeping the quartz sleeve centered vertically in the unit.
9. Replace the bottom manifold (see Fig. 7.7) by installing the four nuts in an alternating pattern (top
left, bottom right, bottom left, then top right). Check again for Teflon washer.
