Water Care Schedule
Before Use:
Each me before the unit is used, check the water with a test strip for proper sanitaon levels and adjust accordingly
achieving the opmum 2-4 ppm level. The unit should not be used if the level is 5 ppm or higher.
Every Other Day: Using test strips, monitor the pH, alkalinity and sanizer levels. The pH should read between 7.4-7.6, alkalinity
between 100-120 ppm.
Weekly: Add non-chlorine shock as needed to maintain correct level dependent upon amount of users, frequency and length of
use during that week.
Monthly: Change the cartridge filter. Soak overnight in a non-sudsing cleanser, preferably Filter Clean available at your retailer.
Rinse well and replace. Be sure to turn off all circulaon for removal and replacement. Review in Maintenance secon.
Every 6 Months: Drain and refill your unit. Wipe down the acrylic surface, install a clean filter. Refer to the Maintenance
secon.
