NOTE:
Well water may contain high concentrations of minerals. The use of a low water volume, extra-fine pore water filter (in-line pre-filter such as
the FreshStart
®
10,000
pre-filter) will help to remove many of the larger particles during the filling of the spa. In-line pre-filters can be purchased at
your local Hot Spring
®
dealer.
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
The FreshWater
®
III high output ozone system is the only ozone purification system approved for installation in your Hot Spring
®
spa. 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). 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 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.
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.
