Specifications

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 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’T 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.

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 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.
