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 (OPTIONAL)
The Monarch high output ozone system is the one of two 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 Monarch high output ozone system unit is less susceptible to the effects of freezing temperatures because it is installed in the equipment compartment. 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 CANNOT 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.
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. Locate the ozonator in the equipment compartment and unplug the ozonator from the control box.
4. Place 16 ounces 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.
5. Carefully loosen the long Norprene
®
tubing to the bottom of the ozonator. A liquid substance may be found inside the tubing. If a liquid substance is present,
BE CERTAIN NOT TO COME INTO CONTACT WITH THE LIQUID (SEE WARNING ABOVE).
6. Place the end of the tubing into the vinegar, making certain that the end of the tubing sits at the bottom of the container.
7. Reconnect power to the spa.
8. Run the spa until all 16 ounces of the vinegar are gone. This should allow an ample flow of vinegar to be run through the injector and clear the blockage.
9. Disconnect power to the spa.
10. Remove the empty cup or bucket.
11. Reinstall the tubing to the bottom of the ozonator.
12. Plug the ozonator into the control box.
13. Close the equipment compartment door.
14. Reconnect power to the spa.
PUREWATER
TM
OZONE SYSTEM (OPTIONAL)
The PureWater ozone system operates during filter cycles to disburse ozone into the spa through an ozone jet located in the footwell of the spa. Water flow from the
ozone system should be checked periodically; small bubbles should be seen rising from the ozone jet.
DOS AND DON’TS
• DON’T use swimming pool (muriatic) acid to lower pH.
• DON’T splash pH increaser additives on the siding.
• DON’T misuse Compressed Sanitizers.
WATER QUALITY AND MAINTENANCE
18
Nitric acid accumulates in the air lines of the ozonator and injector. Nitric acid
will cause severe chemical burns if direct skin contact is made, so always
wear protective gloves, glasses and clothing when working on the ozonator
or injector lines. To prevent inhalation or ingestion of the nitric acid, DO NOT
blow or inhale with your mouth to any of the adapters, fittings or tubing of
the ozonator or injector air lines.
