Watkins Hot Spot Owner's Manual - page 26
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 (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.
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 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 (1/2 liter) 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.
IMPORTANT: When using the FreshWater
®
III high output ozone system, the circulation cycle must be activated to ensure adequate ozone
circulation. Refer to the circulation cycle in the HEATING AND HYDROMASSAGE SYSTEM section for more information.
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 use Compressed Sanitizers.
The use of bromine sticks or tablets in floaters, 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.
The spa shell can easily withstand the effects of a properly administered sanitizer. Floating dispensers can become trapped in one area and cause
an over-sanitization (or chemical burn) of that particular area.
If the dispenser setting is too high, the high concentration can discolor the spa shell and damage the underside of the cover.
Automatic floating dispensers have a tendency to either over-brominate or under-brominate as the rate of erosion varies greatly. Damage to the
spa and cover can occur very quickly.
WARNING: Watkins Manufacturing Corporation DOES NOT recommend the use of any floating chemical dispenser. Damage to the spa shell
or components caused by a floating chemical dispenser is specifically not covered under the terms of the limited warranty.

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.
