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.
CHlORINE (SOdIUM dICHlOR)
A. sanitizing chemicals, such as chlorine, are oxidants that kill bacteria and viruses in the water.
The Free Available chlorine (FAc) is a measure of the amount of unused chlorine available to
sanitize the spa. The recommended FAc for your spa water is 3.0-5.0 ppm.
B. Watkins Manufacturing corporation recommends the use of sodium dichlor type granulated
chlorine for sanitizing the water. sodium dichlor is preferred because it is totally soluble,
dissolves quickly and is nearly pH neutral.
c. Maintaining the proper level of chlorine during use is extremely important.
d. If the FAc is too low, bacteria and viruses can grow rapidly in the warm water.
Increase the
FAC by adding granulated sodium dichlor.
E. If the FAC is too high, the water can cause discomfort to the user’s eyes, lungs and skin.
Simply allow some time to pass. The FAC level will naturally drop over time.
F. The spa is ready to use when the Free Available chlorine is within the recommended range.
WaRNING:
There are several forms of stabilized chlorine available for use in spas and swimming pools and each form has specific
chemical characteristics. It is extremely important that the one you choose is specifically designed for use in spas. use of an incorrect
product such as tri-chlor, which has a very low pH (2.6), dissolves too quickly in hot water resulting in extremely high levels of chlorine, and
is designed for concrete or plaster swimming pools,
WILL
cause damage to your spa. use of a liquid or any type of compressed bromine or
chlorine, acid or any type if sanitizer which is not recommended by Watkins Manufacturing corporation
WILL
damage your spa and is
specifically not covered under the terms of the limited warranty.
ImpORTaNT:
Granulated chlorine (sodium dichlor) will degrade if stored improperly. We recommend purchasing chlorine in one or two pound
containers and storing it in a cool, dry place to maintain its potency.
SUPer CHLorInaTIon
super chlorination is designed to “burn-off” the build-up of chloramines (used chlorine), to eliminate the chlorine smell and to allow the proper level
of free chlorine to be maintained.
When giving your water a super chlorination treatment, open the cover at least half way for twenty minutes to allow the chlorine gas to vent off.
The high concentration of chlorine gas which may exist as a result of super chlorination (not daily sanitation) may eventually cause discoloration or
