III high output ozone system uses Corona Discharge technology to produce a high concentration of ozone which is injected
into the spa water.
Monopersulfate (MPS) is an oxidizing chemical used to prevent the buildup of contaminants, maximize sanitizer efficiency, minimize
combined chlorine, and improve water clarity.
FreshWater
Ag

®
silver ion purifier introduces silver ions into the spa water, inhibiting bacteria growth. When combined with MPS, or
chlorine, oxidizes particulates in the spa water.
It is important to follow the recommended application and maintenance programs outlined for each product’s use.
If the spa is being used over an extended period of time, such as a whole afternoon or evening, additional sanitizer will be needed.
A weekly “shock treatment” is required.
The shock treatment quickly destroys any remaining contaminants while revitalizing the silver ion cartridge, allowing the silver ions to
continue to be released into the water. Without this weekly shock treatment, the silver ion cartridge may stop releasing silver ions into
the water.
To weekly “shock treat” your spa you may use either MPS or sodium dichlor. It will require much less sodium dichlor to administer the
shock treatment than MPS (one teaspoon of sodium dichlor has oxidizing capabilities comparable to two tablespoons of MPS). Sodium
dichlor may be a more appropriate weekly shock for those users that experience heavy bather load conditions.
IMPORTANT NOTE: MPS is an oxidizer, not a sanitizer.

SILVER ION PURIFIER REPLACEMENT
INSTRUCTIONS
When replacing the FreshWater
Ag
+
silver ion purifier (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 sodium dichlor (See Sanitization Table for details).
Fold back the vinyl cover.
1.
Carefully remove and set aside the filter compartment cover.2.
Remove any floating items within the filter compartment.3.
Locate the grey filter cap. Turn the filter cap counterclockwise until the cap can be removed from the filter standpipe.4.
Remove and clean filter cartridges.5.
NOTE: When replacing the FreshWater
Ag
+
silver ion purifier, it is an excellent time to clean and rotate the filters to extend their lives. To rotate
the filters, simply move the filters from one standpipe to another. Typically, the filter on the circulation system (with grey 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.

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 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
Ag
+
silver ion purifier cartridge be replaced?
Answer: The cartridge must be replaced every four months. Please refer to the instructions provided with each FreshWater
Ag
+
silver ion
purifier cartridge.
