Important

Follow the directions for installation and connection. The ozonator is not suitable for medical use. We
reserve the right to change the product and the specification without notice.

Safety rules

A. Install the ozonator in a dry and well-ventilated place.
B. Mount the ozonator at least 3 cm above the floor.
C. The unit is non-servicable, do not dissassemble, it is not possible to change the wire.
D. Cables must be as short as possible outside the ozonator.
F. The ozonator is designed to comply with Safety Class I and must be electrically connected only in
accordance with EN 60335-1 and EN 60335-2-60. We recommend that you consult a certified
electrician.
G. At all times keep a minimum of 20 mm distance between high and low power cables.
H. The installation should be carried out so that it is impossible for the user to touch the ozonator.
J. The electric parts have to be mounted in such a way that they cannot fall into the spa.
K. External earth screw on the ozonator to be used for connection of external equipotential bonding.

Introduction to Ozone

Ozone (O ) is generated by irradiating air or oxygen (O
3
oxygen that is formed when three atoms of oxygen are bound together instead of the normal two atoms.
The extra oxygen atom makes ozone the most powerful oxidizer and sanitizer readily available.
Since ozone is unstable and quickly decomposes to oxygen under normal conditions, it cannot be shipped
or stored. Therefore, it must be manufactured on site for immediate use. In air it lasts about an hour. In
pool water it lasts just long enough to purify the water - less than 1 second.
Although ozone is mainly thought of as a sanitizer, it acts primarily as an oxidizer in the pool environment.
In a typical spa run on chlorine only, up to 90 percent of the chlorine may be used up in reactions
unrelated to disinfection. The byproducts of these reactions are combined chlorines. Combined chlorines
are the cause of eye irritation, odor, and the other unpleasant side effects of chlorination.
When ozone is used, it oxidizes a large portion of the contaminants (usually referred to as bather load)
which results in the reduction of combined chlorines. The result is that more chlorine is available for
disinfection and less chlorine is required to maintain the pool which eliminates the harmful byproducts.
Even though ozone provides some disinfection, the use of chlorine or bromine is always recommended.
