CAOZN1 & CAOZNB
Ozone Generator & Lamp
Ozone is a naturally occurring molecule which is produced in the upper atmosphere when UV (ultra-violet) light strikes oxygen.
The earth’s “Ozone layer” protects us from harmful UV rays. Ozone is also produced during thunderstorms… that fresh smell after a
rainstorm is ozone.
Overview
•
The CAOZN1 and CAOZNB Ozone Generator safely produces ozone by using a
UV / ultra-violet light. Other ozone generators use a charged “corona discharge”
grid, which can be dangerous to operate.
• Ozone is a very powerful “oxidizer” which means it can sterilize water and air by
attaching itself to offending odors and destroying them by actually changing
their chemical composition.
• When used properly, levels far below the OSHA and EPA limits are maintained
with no harmful effects
What is Ozone?
Ozone (O3), is a strange and reactive molecule consisting of three atoms of oxygen
(O1). Ozone is created when UV light strikes a molecule of oxygen (O2), which has
two atoms of oxygen. The molecule is split into two individual atoms of oxygen
that are free to attach to two molecules of oxygen producing ozone (O3). The third
atom of oxygen is “weakly” attached to the molecule, which makes it very unsta-
ble and able to react quickly with pollutants. When a molecule of ozone “bumps”
into an offending odor, the third “weakly” bonded atom of oxygen attaches to the
odor molecule, which destroys the chemical’s “smell” thus eliminating odors. The
simple equation is UV light + O

How to use CAOZN1 & CAOZNB
The CAOZNI and CAOZNB are very easy to use. Most people find a location to hang
the unit on a wall away from human activity. It does not have to be directly by the
source of odors because they can effectively treat up to 5500 cubic feet. When the
unit is plugged in and the switch on the side is turned on, the fan draws in air and
passes it over the UV lamp located inside the powder-coated steel enclosure. The
lamp itself is surrounded by a highly reflective aluminum chamber that increases
the efficiency of the unit resulting in a higher output of ozone. Ozone is created
inside the unit and is expelled from the exit hole in the end of the unit.
The unit can also be located inside air return ducts. Another way to use it is to
allow the ozone to mix with exhaust from a closed area by placing only the exit
hole inside the ducting or use a short piece of tubing / hose from the hole to
the ducting.
The turbulence created when the air flows through the ductwork increases the
“mixing” of the ozone to fully neutralize all odors. If you want to reduce the level
of ozone being produced, simply plug it in to a cycle timer. Keep in mind that the
more the lamp cycles on and off, the quicker the lamp will burn out. Use a timer
that doesn’t cycle too fast and the lamp should last for years.

Overview

1. Function Description
2. Usage Features
3. Maintenance Features

The CAOZN1 & CAOZNB Ozone Generator & Lamp is a device designed to produce ozone for air and water sterilization, effectively neutralizing odors and pollutants. Ozone, a naturally occurring molecule, is generated when UV light strikes oxygen. This process mimics how the earth's ozone layer is formed and the fresh smell experienced after a thunderstorm.

Function Description

The core function of the CAOZN1 & CAOZNB is to generate ozone using UV/ultra-violet light. Unlike some other ozone generators that rely on a charged "corona discharge" grid, this device utilizes UV light, which is considered a safer method of ozone production. Ozone (O3) is a highly reactive molecule composed of three oxygen atoms. When UV light interacts with a standard oxygen molecule (O2), it splits the O2 into two individual oxygen atoms (O1). One of these free oxygen atoms then attaches to another O2 molecule, forming O3. The third oxygen atom in the O3 molecule is "weakly" attached, making the molecule unstable and highly reactive. This instability allows ozone to readily attach to and react with pollutants and odor molecules. When an ozone molecule encounters an odor molecule, its weakly bonded oxygen atom detaches and binds to the odor molecule, chemically altering and destroying its "smell." This process effectively sterilizes both air and water by breaking down the chemical composition of offending odors and pollutants. When used properly, the device maintains ozone levels well below OSHA and EPA limits, ensuring no harmful effects.

Usage Features

The CAOZN1 & CAOZNB is designed for ease of use. Most users find it convenient to hang the unit on a wall, away from areas of high human activity. Its placement does not need to be directly adjacent to the odor source, as it can effectively treat spaces up to 5500 cubic feet. To operate, the unit is simply plugged in, and the side switch is turned on. Once activated, an internal fan draws in ambient air, which is then directed over a UV lamp housed within a powder-coated steel enclosure. The lamp is surrounded by a highly reflective aluminum chamber, which enhances the unit's efficiency and increases ozone output. The ozone generated inside the unit is then expelled through an exit hole at the end of the device.

The unit offers versatile placement options. It can be located within air return ducts, allowing the ozone to mix efficiently with exhaust from a closed area. This can be achieved by positioning only the exit hole inside the ducting or by connecting a short piece of tubing or hose from the exit hole to the ducting. The turbulence created by airflow within the ductwork aids in the thorough mixing of ozone, ensuring complete neutralization of odors.

For users who wish to regulate the level of ozone produced, the device can be connected to a cycle timer. This allows the unit to turn on and off periodically, reducing the overall ozone output. It's important to note that while using a timer can help manage ozone levels, excessive cycling (turning the lamp on and off too frequently) can shorten the lamp's lifespan. A timer that cycles at a moderate pace is recommended to ensure the lamp lasts for years.

Maintenance Features

The CAOZNI and CAOZNB are designed with safety and minimal maintenance in mind. A key safety feature is a built-in shut-off switch that automatically deactivates the UV lamp if the enclosure is opened. This prevents direct exposure to UV light, which can cause severe eye damage, similar to how direct sunlight can burn skin. It is crucial to always unplug the unit before attempting any maintenance or opening the enclosure.

The only routine maintenance required is cleaning the lamp and reflector. This should be done approximately once every six months to ensure the unit maintains peak performance and ozone output. The red, lighted power switch serves as a visual indicator that the unit is receiving power and provides a straightforward way to turn the device off.

Troubleshooting guidance is provided for common issues. If the power switch does not light up, users should check the power supply and try plugging the unit into a different, known-working outlet. If the power switch is lit but the unit is not working, it's important to verify that the unit is properly closed and all eight screws are in place, as the safety switch requires the enclosure to be fully closed for the lamp to receive power. If the fan is running but the light does not fire, users should first disconnect power, then open the unit to check if the lamp is properly connected to the 4-pin socket assembly. If the light still doesn't fire after reassembly, the UV lamp may need replacement.

For concerns about a strong "ozone" odor, which can indicate high ozone levels, users are advised to increase ventilation or relocate the unit to an area not directly around people. Connecting the unit to a timer to cycle it on and off can also help reduce ozone levels. If a sore throat develops after ozone exposure, it suggests excessive exposure (above .15 ppm). In such cases, increasing ventilation is recommended. Individuals with asthma or chronic respiratory diseases should exercise caution and avoid using the ozone generator in closed areas if they experience adverse effects, as prolonged exposure to high concentrations of ozone (over .5 ppm) can damage the lungs. The device should only be used with a timing device for safe and reliable operation, and it should always be unplugged from the power source before cleaning.
