How do I clean the Salt Cartridge?

1. Turn off the power to the spa. Open the spa cover and remove the housing cap.
2. Remove the Salt Cartridge from the housing.
3. Inspect the salt cartridge for scale by looking between the electrodes (scale will be more visible when dry).
4. Place the salt cartridge in the FreshWater Cell Cleaner.  If you do not have FreshWater Cell Cleaner you can also use a pH down solution (3 tablespoons pH down in 12 ounces of water) or vinegar.  NOTE: A stronger cleaning solution of 1 part muriatic pool acid and 10 parts water, or a commercial cell cleaner, can be used if scale is excessive
5. Soak the salt cartridge for 10 minutes or until bubbles stop coming from the cartridge. If bubbles are still releasing from the cartridge after 10 minutes, continue soaking until the cartridge is clean and all scale is removed. The salt cartridge can be soaked for up to an hour as added time
6. Rinse the salt cartridge and inspect for cleaning completion. Repeat as needed.
7. Replace the salt cartridge into the housing. Replace the housing cap and power up the spa
