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 residual 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 four months before needing to be
drained.
OZONE
Ozone is a powerful oxidizing agent which is produced in nature, and artificially by man. Ozone will oxidize a wide range of water contaminants,
from soap residue to bacteria.
The FreshWater
®
III high-output ozone system is the only ozone purification system approved for installation in your Tiger River
®
spa. The
FreshWater III ozone system features Corona Discharge (CD) technology to produce a higher concentration of ozone than is produced by
competing ultraviolet light (UV) ozone systems.
The under-the-cabinet mounted FreshWater III high-output ozone system 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 FreshWater III high
output ozone system.
The FreshWater III 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
NOT be used as a single-source sanitizer, water clarifier, anti-foamer, and mineral chelating agent. A secondary source sanitizer must be used
to maintain 2.0 ppm (2.0 mg/L) of Free Available Chlorine (FAC). 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 Tygon/Kynar 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 ON PREVIOUS PAGE).
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.
Water quality and Maintenance
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.
