FRESH SILvER ION PURIFIER REPLACEMENT
When replacing the 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 WATER TREATEMENT GUIDE for details).
1. Fold back the vinyl 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 filler cap counterclockwise until the cap can be removed from the filter standpipe.
5. Remove and clean filter cartridge.
NOTE:
When replacing the FreshWater
®
Ag+
silver ion purifier, it is an excellent time to clean and rotate the filter to extend its life. To rotate the
filter, simply replace the existing filter with another one. Then clean and store the old one until the next time the FreshWater
Ag+
silver ion purifier
needs replacement.
6. Remove the existing FreshWater
Ag+
silver ion purifier.
7. Install the new FreshWater
Ag+
silver ion purifier into the filter standpipe. Do not force the FreshWater
Ag+
silver ion purifier down into the filter
standpipe.
8. Reinstall the cleaned filter cartridge.
9. Replace and secure the gray filter cap.
10. Replace the filter compartment cover.
11. Fold the cover back into place.
WARNING:
Never use the spa with the filter cartridge or filter standpipe 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 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.
Question:
Can I use the FreshWater III ozone system in addition to the silver ion system?
Answer:
Yes. In fact, it is preferred! The use of the FreshWater III ozone system will enhance the performance of the silver 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?
Answer:
Bromine and biguanides will chemically react with the sanitizing action of the silver
ions. This will eliminate their beneficial sanitizing effect.
dOS and dOn’TS
• DO
check your MPS or sodium dichlor chemical level prior to each use.
• DO
check your sanitizer prior to each use.
• DO
change the FreshWater
Ag+
silver ion purifier every four months.
• DO
test Total Alkalinity and pH weekly.
• DO
use MPS for spas only, such as Hot Spring
®
MPS chlorine-free oxidizer.
• DO
store all chemicals in a tightly sealed container in a cool, dry place.
• DON’T
use bromine or biguanides. These are active sanitizers and will combine with the
silver ions to inactivate them.
• DON’T
use a water clarifier. Clarifiers will cause the spa water to become cloudy.
