3.  Remove the black bulb boot (8) by sliding it over the cable away from 
the quartz seal compression nut (7), Figure 3.
4.  Slowly remove the UV bulb (4) out of the quartz tube.
5.  Remove bulb socket (5) from the UV bulb (4), Figure 4.
6.  Remove the quartz seal compression nut (7) by turning it 
counterclockwise, Figure 3. Use a pair of channel-lock pliers if 
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),

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: Do not use abrasive cleaners as they can 
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 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.
11.  Reinstall the compression washer (6) over the open end of the quartz 
tube (2). Push it against the quartz black seal ring (13).
12.  Reinstall and hand tighten the quartz seal compression nut (7) by 
turning it clockwise.
13.  Rell your spa.
