Pure XL™ and Pure Cure™ Water Sanitizers
The Pure XL™ and Pure Cure™ water sanitizers are optional water purification systems installed at the factory.
They eradicate germs in the water that are resistant to chlorine-based chemicals using high intensity UV
light.
Both water sanitizers work automatically during the spa’s filtration cycle. We recommend increasing filtration
time setting from F2 (two hours twice a day) to F6 (six hours twice a day). See page 16 or page 19 for setting
filtration cycle.
Both water sanitizers are virtually maintenance-free. Once a year the UV light needs to be replaced. See
page
44
for instructions.
However, the water sanitizer is not a user-serviceable item and maintenance
must be performed by a spa technician . Have your service technician consult the manufacturer’s
instruction and service manual .
Filter Cleaning
The filter is the part of your spa that removes the debris from the water and needs to be cleaned on a regular
basis to maximize your spa’s filtering performance and heating efficiency.
In addition to spraying off the filter weekly to remove surface debris, your filter should be deep cleaned
periodically to dissolve scale and particles that get lodged deep within the filter fibers and impede the
filtration process. Even if the filter looks clean, scale and particles can clog the fibers and prevent water from
flowing through the filter resulting in the most common spa problem—no heat, caused by a dirty filter.
We recommend you clean your filter once a month and replace it once a year or as necessary.
Remove the filter by turning it counterclockwise, unscrewing the bottom threads, then pulling it up and

out.
Place the dirty filter into a bucket of water deep enough to cover the filter. Add 8 oz of liquid filter cleaner

to the bucket of water.
Note:
It is a good idea to keep a spare filter to use in the spa while the dirty filter is being deep cleaned.
This way, you can rotate the filters and both will last longer.
Soak the filter for a minimum of 24 hours.
3.
Spray the filter with a water hose. Spray each pleat carefully.
4.
Reinstall the filter. Do not overtighten.
5.
Ozonator
The ozone generator releases ozone into the spa water. You will still need to test for chlorine or bromine and
occasionally replenish it to return the sanitizer level to the baseline.
Set the spa’s filtration time for “F4” (described on
page 16 and page 19). This activates the ozonator and
produces the ozone gas. Note: Filtration time may need to be increased with heavy bather load.
