About the Pure XL Water Sanitizer

The Pure XL water sanitizer is an optional water purification system installed at the factory. It works 24 hours
a day with the continuous filtration pump during normal operation of the spa. It eradicates germs in the
water that are resistant to chlorine-based chemicals using high intensity UV light.
There are no settings to adjust and is virtually maintenance-free. Once a year the UV light needs to be
replaced and the quartz sleeve needs to be cleaned.
This 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 . (UV
water purifier system is manufactured by Aqua Ultraviolet.)

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.
1. Remove the filter by turning it counterclockwise, unscrewing the bottom threads, then pulling it up and
out.
2. Place the dirty filter into a bucket of water deep enough to cover the filter. Add 8 oz of Cal Spas "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.
3. Twist off the tablet tube and set it aside.
4. Soak the filter for a minimum of 24 hours.
5. Spray the filter with a water hose. Spray each pleat carefully.
6. Put fresh bromine in the tablet tube (if you use it as a sanitizer) and twist it back on top of the filter.
7. Reinstall the filter. Do not overtighten.
