Ozone - HotSpring Portable Spaa Owner's Manual

OZONE

®
The FreshWater III 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 FreshWater III 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 FreshWater III high
output ozone system .
®
The Hot Spring spa 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.
NOTE: Not applicable when using the AutoFresh
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.
Nitric acid accumulates in the air lines of the ozonator and
WARNING
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.
5. Carefully loosen the long clear 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.
DOS AND DON'TS
• DO add all chemicals slowly into the filter compartment with the jet pump operating for ten minutes.
• DO use special care if using baking soda to clean either the interior or exterior plastic surfaces.
• DON'T use swimming pool (muriatic) acid to lower pH.
• DON'T use compressed sanitizers.
The use of bromine sticks or tablets in floater, which may become entrapped in a lounge or cooling seat (or sink to the spa floor), have been
shown to cause discoloration of or surface distress to a spa's shell.
• DON'T use a floater type sanitization system as a low or no maintenance solution to your spa maintenance program.
