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 degradation to the bottom of the cover, which would not be covered under the terms of
your warranty.
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 or 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, two, or five pound containers and
storing it in a cool, dry place to maintain its potency.
IMPORTANT: Always allow the Free Available Chlorine to fall below 5 ppm before using the spa.
WARNING: Never leave an open spa unattended, especially if there are children present!
SUPPLEMENTAL WATER MAINTENANCE
Proper water sanitation and mineral balance (pH control) are absolutely essential for a complete spa water maintenance program. Here are three other popular water
additives that are optional:
Mineral Deposit Inhibitors
As water evaporates from your spa and new water is added, the amount of dissolved minerals will increase. (Minimize evaporation by keeping the cover on the spa
whenever possible.) The spa water may eventually become “hard” (Calcium Hardness too high) enough to damage the heater by calcifying its surface. Proper pH control
can minimize this.
Normal soap build-up will require water replacement regularly enough that mineral deposits normally are not a problem.
Occasionally, high iron or copper content in the water may produce green or brown stains on the spa. A stain and scale inhibitor may help to reduce these metals.
NOTE: Well water may contain high concentrations of minerals. The use of a low water volume, extra-fine pore water filter will help to remove many of the larger
particles during the filling of the spa.
Foam Inhibitors
Spa water requires changing due to the buildup of soap in the water. Typically, soap will cause the spa water to foam when the jets are used. Soap is introduced into the
spa water from two sources: users’ bodies, which retain a soap residue after showering, and swimming apparel, which retains soap after washing.
Foam inhibitors can suppress foam, but cannot remove soap from the water. Soap is very difficult to remove from the water because soap is not oxidized by any
chemical added to the spa. Only ozone can oxidize soap.
Eventually the soap build-up in the water will be concentrated, resulting in an unclean feeling on the bather’s skin, which is impossible to remedy. When this occurs, it’s
time to drain and refill the spa. Depending on the soap input, the water should last about 4 months before needing to be drained.
MONARCH OZONE SYSTEM
The Monarch high output ozone system is the 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 ultraviolet light (UV) ozone systems.
The under-the-skirt mounted Monarch high output ozone system unit offers less-visible installation and is less susceptible to the effects of freezing temperatures. To
access it for inspection, remove the equipment compartment door to check the unit operation (this is usually done prior to disconnecting the power to the spa before
draining). Simply listen for the buzz of the transformer to verify operation of the Monarch high output ozone system.
The Monarch high output ozone system greatly enhances the quality of the spa water when used to supplement the spa owner’s regular water maintenance program.
Contrary to some information circulated throughout the pool and spa industry regarding ozone systems, ozone CAN’T be used as a single-source sanitizer, water
clarifier, anti-foamer, and mineral chelating agent. Watkins Manufacturing Corporation recommends that a chemical maintenance program based on recognized and
documented industry standards still be followed when using an ozone purification system to assure water sanitation and the highest quality purified water.
NOTE: It is not recommended to use granulated bromine with ozone.
Cleaning the Ozone Injector
On occasion, a mineral build up may clog the ozone injector, causing a lack of flow or low flow, of ozone bubbles. To prevent this, refer to the following instructions to
clean the injector:
1. Disconnect power to the spa.
2. Access the equipment compartment.
3. Place 1/2 liter of white vinegar into a container such as a cup or bucket. Place the container on the equipment compartment floor. NOTE: White vinegar will not
damage any of the spa components.
