MAINTAINING THE SANITIZER LEVEL
A. Sanitizer is extremely important for killing algae, bacteria and viruses, and preventing unwanted organisms from growing in the spa. At the same time, you don’t
want too high a sanitizer level, or it can irritate your skin, lungs, and eyes.
B. Always maintain the sanitizer level in your spa at the recommended level for each type of sanitizer.
C. Watkins
®
recommends only the following sanitizers:
• Sodium Dichloro-s-Triazinetrione (sodium dichlor or chlorine)
• BaquaSpa
®
(please consult your BaquaSpa manual for instructions on the use of this product).
• Brominating Concentrate
™
(one step granular bromine)
WARNING:
DO NOT use tri-chloro chlorine, bromo-chloro-dimethyl-hydantoin (BCDMH), or any type of compressed bromine or chlorine, acid or any type of sanitizer
which is not recommended by Watkins Manufacturing Corporation.
MONARCH
®
WATER CARE SYSTEM
The Monarch Water Care system is comprised of the following products:
•
Monarch 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.
•
Monarch CD Ozone Generator -
The Monarch high output ozone system is the only ozone purification system approved for installation in your Caldera
®
Spa.
The Monarch ozone system utilizes Corona Discharge (CD) technology to produce a higher concentration of ozone than is produced by competing chip style
CD or ultraviolet light ozone systems.
•
Monarch Non-Chlorine Oxidizer Monopersulfate (MPS)
is an oxidizing chemical used to prevent the buildup of contaminants, maximize sanitizer efficiency,
minimize combined chlorine, and improve water clarity.
•
Sodium Dichlor (chlorine)
is the only recommended sanitizer that will work in conjunction with all of the other products in this system.
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 or 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 cartridge, allowing the silver ions to continue to be released into the
water. Without this weekly shock treatment, the silver 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 (1
teaspoon of sodium dichlor has oxidizing capabilities comparable to 2 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.
MONARCH SILVER CARTRIDGE REPLACEMENT INSTRUCTIONS
When replacing the silver cartridge (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.
1. Release the cover locks and fold back the cover.
