Maintenance of Spa Water and Cartridge
Protect all the spa occupants from possible water related illness by keeping the spa water clean and sanitized.
Always practice good hygiene. To ensure proper spa water quality by following these procedures:
1. Inspect and clean the filter cartridge after each use, and change the filter cartridge after it works
continuously for 72 hours.
● Unscrew the cartridge assembly from the spa tub wall and remove the cartridge by turning it counter
clockwise (Fig. 1.1)
● Use a garden hose to rinse off the cartridge. If the cartridge remains soiled and discolored it should be
replaced. Keep spare cartridges on hand.(Fig.1.2).
● Reinstall the clean or spare cartridge back onto the spa tub wall but turning it on clockwise. (Fig.1.3)

2. Change the spa water every 3-5 days depends on the spa use. See “Cleaning, draining and storage”
section for instruction.
3. Use spa chemicals to maintain proper water chemistry. Spa damage resulting from misuse of chemicals
and mismanagement of spa water is not covered by the warranty. Consult with your local spa or pool
retailer for more information on chemical use.
4. All occupants must shower before entering the spa.
5. When spa inlet or outlet is stuck with dirt. Use the
Wrench to check the problem and clean the inlet
or outlet.
Water Balance
Maintain the spa water pH level between 7.2 and 7.8, total alkalinity between 80 and 120ppm and free chlorine
level between 3 to 5ppm. Use the *optional Test Strips to test the spa water chemistry before each use of the
spa and continue to test the water no less than once a week.
The Test Strips can test the “Free Chlorine”, “pH”, and “Total Alkalinity” level at the same time:
1. Dip the entire strip into the water and remove immediately
2. Hold the strip level for 15 seconds. Do not shake excess water from the strip
3. Compare the strip pad to the color chart on the packaging label. If necessary, adjust the chemical level in
the pool water

CAUTION:
● Always follow the chemical manufacturer’s direction, and the health and hazard warning.
● Do not add chemicals if the spa is occupied. This can cause skin or eye irritation.
● Concentrated chlorine solutions can damage the spa tub. Improper chemical use will void the warranty.
