and shower lime removal product can be used.

scratch the quartz tube surface.
!

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 rst making sure it is inserted and seated inside the
quartz end holder. Only a small portion will be exposed when it is
seated correctly.
