FRESHWATER
REPLACEMENT INSTRUCTIONS
When replacing the Silver Ion Purifer (every four months), it is highly recommended that the spa be drained and refilled at the
same time. After refilling the spa with water, balance the Total Alkalinity (TA), Calcium Hardness (CH) and pH to the
recommended levels. Shock the spa by adding sanitizer, either MPS or sodium dichlor (See Sanitization Table for details).
1. Fold back the cover.
2. Carefully remove and set aside the filter compartment cover.
3. Remove any floating items within the filter compartment.
4. Locate the gray filter cap. Turn the filter cap counterclockwise until the cap can be removed from the filter standpipe.
5. Remove and clean filter cartridges.
NOTE: When replacing the FreshWater
extend their lives. To rotate the filters, simply move the filters from one standpipe to another. Typically, the filter on the
circulation system (with gray filter cap, standpipe and wallfitting) is subject to the greatest load. By rotating the filters, the
load placed on the individual filter by the circulation system is greatly reduced. This extends the life of the filters.
6. Remove the existing FreshWater
7. Install the new FreshWater
Purifier down into the filter standpipe.
8. Reinstall the cleaned filter cartridges.
9. Replace and secure the gray filter cap.
10. Replace the filter compartment cover.
11. Fold the cover back into place.
WARNING: If the removal of the standpipes is necessary, always reinstall the gray standpipe in the gray wallfitting at the
bottom of the filter compartment. Never use the spa with the filter cartridges or filter standpipes removed!
SILVER IONS QUESTIONS AND ANSWERS
Question: How are the silver ions actually added to the water?
Answer: The silver ion cartridge contains ceramic beads that are infused with silver. By placing the cartridge in the circulation
pump filter standpipe, it is subjected to the continuous flow of water created by the pump's 24 hour circulation. The flowing
water, through a chemical erosion process, carries with it the silver ions necessary to add a sanitizing residual to the spa
water.
Question: What other types of oxidizers can be used during the active sanitation process?
Answer: As an alternative to the MPS, sodium dichlor (granular chlorine) may be substituted during the active sanitation
process. 1 teaspoon of dichlor equals 2 tablespoons of MPS.
Question: What happens if I do not add the weekly shock treatment?
Answer: The contaminants in the water may coat the silver ion cartridge's ceramic beads, blocking the silver ions' release
into the water. When this occurs, there will be no residual of silver ions present in the water, eliminating them from the
sanitizing process.
Question: How often should the FreshWater
Answer: The cartridge must be replaced every four months. Please refer to the instructions provided with each

Question: Can I use the FreshWater
Answer: Yes. In fact, it is preferred! The use of the FreshWater
ions and may substantially reduce the need for supplemental chemical treatments when the spa is not in use.
Question: Why can't I use bromine or biguanides instead of MPS or chlorine as my sanitizer?
Answer: Bromine and biguanides will chemically react with the sanitizing action of the silver ions. This will eliminate their
beneficial sanitizing effect.
Question: I see different types of MPS in my local pool supply store. Which one should I use?
Answer: Generally, two types of non-chlorine shock (containing MPS) are available: one for swimming pools and one for
spas. Use only non-chlorine shock designed for use in spas, such as Hot Spring
may contain a clarifier (typically blue crystals in the shocking agent). The clarifier will react with the silver ions and cause the
water to appear cloudy and reduce the effectiveness of the silver ions.
