Filter Cleaning
The lter 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 ltering performance and heating efciency.
In addition to spraying off the lter weekly to remove surface debris, your lter should be deep cleaned
periodically to dissolve scale and particles that get lodged deep within the lter bers and impede the
ltration process. Even if the lter looks clean, scale and particles can clog the bers and prevent water from
owing through the lter resulting in the most common spa problem—no heat, caused by a dirty lter.
We recommend you clean your lter once a month and replace it once a year or as necessary.
Remove the lter by turning it counterclockwise, unscrewing the bottom threads, then pulling it up and 1.
out.
Place the dirty lter into a bucket of water deep enough to cover the lter. Add 8 oz of Cal Spas “Liquid 2.
Filter Cleaner” to the bucket of water.
Note: It is a good idea to keep a spare lter to use in the spa while the dirty lter is being deep cleaned.
This way, you can rotate the lters and both will last longer.
Twist off the tablet tube and set it aside.3.
Soak the lter for a minimum of 24 hours.4.
Spray the lter with a water hose. Spray each pleat carefully.5.
Put fresh bromine in the tablet tube (if you use it as a sanitizer) and twist it back on top of the lter.6.
Reinstall the lter. Do not overtighten.7.
About the Pure XL Water Sanitizer
The Pure XL water sanitizer is an optional water purication system installed at the factory. It works 24 hours
a day with the continuous ltration 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 purier system is manufactured by Aqua Ultraviolet.)
