needed, Figure 5. You will notice that there is a
stainless steel compression washer (6) that slides
over the quartz tube. Save the washer (6) for later
use, Figure 6. There is also a black seal ring (13),
grasp the black seal ring; slowly and carefully

7. Now you are ready to clean or replace the quartz tube (2).
For the cleaning of the quartz tube (2), follow steps 8 and 9 then
proceed to step 10. For replacing of the quartz tube (2), skip steps 8
and 9 and proceed to step 10.
8. Cleaning quartz tube: Clean the quartz tube by wiping until clear
using a paper towel or a dry cotton cloth. If needed a household tub
and shower lime removal product can be used.
WARNING:
!
scratch the quartz tube surface.
9. Rinse the quartz tube with clean water to completely remove any
cleaning products that were used in step 4.
10. Replacing quartz tube: You will notice that the new quartz tube
does not have a black cushion on the domed end as the old quartz
tube does. This is normal as the cushion was provided with the
original quartz tube to protect it from breakage during transportation.
Install the black seal ring (13) over the opened end of the quartz
tube. Place the new quartz tube (2) into the water chamber (1) with
the domed end first making sure it is inserted and seated inside the
quartz end holder. Only a small portion will be exposed when it is
seated correctly.

quartz tube (2). Push it against the quartz black seal ring (13).
12. Reinstall and hand tighten the quartz seal compression nut (7) by
