FILTER MAINTENANCE
At least once a week, check and clean the skimmer basket and weir to ensure proper filter flow. Remove
leaves, foreign matter, and debris. It is very important to keep your spa filter cartridge clean and free of
particles to ensure proper water flow. A clean filter permits the hydrotherapy system to function properly
and also allows more efficient filter cycles. Depending on how frequently your spa is used, we
recommend cleaning the spa filter cartridge every four weeks. If this is not done, the filter may clog and
restrict water flow, which causes improper filtration and poor jet performance.
WARNING: The frequency and duration of use, and the number of occupants all contribute to
determining the appropriate time between filter cleanings. More use means that more frequent filter
cleanings will be required.

FILTER CARTRIDGE REMOVAL AND CLEANING

Turn the power to the spa OFF, then proceed as follows:
1. Push down slightly and turn filter basket counterclockwise to unlock, then pull the basket and weir
out.
2. Carefully pull up the filter cartridge and bring it out of the spa.
3. Rinse cartridge using a garden hose. Rotate and separate filter pleats while spraying water to
remove all debris possible. Let the filter dry and then look for calcium deposits (scaling) or an oil film.
If you find these, you will need to deep clean your filter cartridge with a “spa filter cleaning” solution
to break down and remove mineral deposits and oils.
4. Install filter then replace basket and weir by inserting and rotating clockwise to lock into position.
