USER GUIDE

Please read all of the informations provided in this user’s guide before operating
your new air unit. from the sun strike hydrocarbons, O3is one of the by-products. Ozone is
easily detected and is sometimes used as a reference point for the level of
pollutants.
Q. How does it compare to air filters?
A. Air Purifier does not rely on the air to actually pass through the machine
to be cleaned like air filters. It’s not a filter at all. Air Purifier produces both
activated oxygen, which reduces odors and negative ions, which settle out
particulate.
Q. Is ozone safe?
A. Yes, but moderation is the key. Ozone in very high concentrations can be
irritating to mucous membranes and the respiratory system. We recommend
you set the O3dial properly. Before using the Air Purifier you should read
the enclosed instructions carefully. Refer to Using a Timer section.
Q. Where should I place the Air Purifier in my home or office?
A. The Air Purifier should be placed in the room where you have the most
pollutants. The Air Purifier is easy to move so you might want to try it in a
couple of locations to help decide what works best for your environment. An
elevated location is better to distribute ions and activated oxygen more
evenly. Air Purifier works best if it is placed within 10 feet of a cold air
return.
Q. How long will the Air Purifier last?
A. The Air Purifier is made of stainless steel and solid wood construction.
Because of the quality material and superior craftsmanship that goes into
each Air Purifier you will enjoy it for many years.
Q. Is it difficult to install?
A. No. Just install O3plates (located in separate box packaged inside the
carton),plug it in and set the dial for the area you will be treating. Install the
Air Purifier in any room, but try to find a place where it can be up off the
ground four feet or more. Some customers prefer to have more than one unit
to better control levels of activated oxygen in the home.

COMMONLY ASKED QUESTIONS
Q. What does the Air Purifier do?
A. It treats the air in your home or office by breaking down odor causing
pollutants and dropping airborne particulate from your breathing space.
Q. How does the Air Purifier treat the air?
A. The Air Purifier produces ozone and negatively charged ions, the same
effective cleansing agents that nature uses to treat outdoor air.
Q. How does the Air Purifier work?
A. It is a two-stage process
1. The Air Purifier uses a needlepoint ionizer to drop dust, smoke
and other harmful particles from the air we breathe. In our
homes and offices there is a lack of negative ions and an
abundance of positive ions. The buildings we spend most of our
time in block out the natural occurring negative ions. The Air
Purifier recreates the natural balance of positive to negative ions
to significantly reduce airborne particulate.
2. The Air Purifier uses electricity to split oxygen O2molecules
into single O1atoms, which attach loosely to other O2molecules
to become O3(activated oxygen). This loosely attached oxygen
atom is unstable and seeks to bond with chemical compounds
and other odor causing pollutants in order to oxidize them.
Q. How does nature produce ozone?
A. Ozone is created electrically during active thunderstorms. The electrical
discharge creates a fresh sweet smell. The ultraviolet rays of the sun
striking hydrocarbons in our atmosphere also create ozone.
Q. How does nature produce ions?
A. Waterfalls, lightning, and the waves of the ocean all create negative ions.
Q. What is an ozone alert?
A. Ozone alerts in cities are a result of the high pollution levels of
hydrocarbons produced by the burning of fossil fuels. When ultraviolet rays

PART FUNCTION
Ionizer ON/OFF On/Off control switch activates needle-point ionizer
& Fan Speed and controls the fan speed. The unit will not function
unless the ionizer control is on.
Ozonator Start O3on low then increase 1 increment every 2
hours until you walk into the room and smell O3.
When you smell the O3, turn back 1 increment. O3
production can be turned on and off as desired.
Fan Grill Removable fan grill. Wash with warm soapy water,
dry completely before replacing.
(Unplug unit before removing)
Control for the negative ion generator is separate from the O3control. Negative
ions can be created around the clock to keep down dust and particulate.
O3also known as activated oxygen is normally kept at modest levels in occupied
spaces. To remove heavy odors, the units may be adjusted to a higher level for
a period of time. Some use a timer to completely deodorize the home or office
while away. Unused O3reverts back to O2in about an hour.
CLEANING & MAINTENANCE
When the purifier no longer produces enough ozone to be effective, the ozone plate
should be cleaned. A good rule of thumb is every month. Some environments cause
ozone output to be reduced in a shorter time but other environments may take longer.
To clean a plate, first turn the unit Off and unplug from outlet. Then remove the 4”x4”
plates from back of unit. Pull plates firmly in the center to remove from the slot. With
plate firmly supported in the hand apply a solution of warm water and ammonia (50/50
solution is suggested) or a strong grease cutting detergent. Scrub with a stiff brush if
necessary. Be careful not to drop the plate or scrub off the silicon. Clean both the metal
screen and the ceramic tile. Rinse plate in hot water and dry completely before
installing. If available you may use a hair dryer to dry the plate. Reinstall plate, making
sure it is secured and flush with the back of the unit. Plug unit into a grounded electrical
outlet, turn unit on and start enjoying clean fresh air.
To clean needlepoint ionizer, first turn Off and unplug from outlet. Remove the fan grill
cover. The needle point ionizer will be easy to find in front of the fan by looking for two
pieces of wire. Take a q-tip or cotton swab dipped in alcohol and clean any dust that may
have accumulated on the needlepoints. This process may be done when plates are being
cleaned. While you have the front grill cover off the unit you may also clean the fan and
grill itself. To clean the fan simply wipe the blades with a damp cloth or vacuum. The
grill cover may also be cleaned with warm soapy water. Be careful that the fan grill
cover is completely dry before installing.
TROUBLESHOOTING
If you suspect a problem with your unit check the following:
Make sure plate is clean (see above).
Unit is plugged in properly and turned on.
Check the fuse to make sure it is installed properly and not burned out. To replace
fuse, push in and turn fuse holder to the left, remove old fuse, replace with spare.
Use 1 amp fuse, 1.25 inches long.
Wall outlet is active
Check plate alignment making sure the ceramic plate is almost flush with back of
unit.
It is important that the Air purifier be properly grounded to avoid potential shock.
If the fan is not operating or after cleaning the plate no buzzing sound is detected on the
high setting of the O3, please contact your local dealer.

Caution: No attempt should be made to remove the back panel of the unit,
as there are no user serviceable parts.

USING A TIMER
Some users who are sensitive to ozone set their units up on a timer so that the
purifier does its work only when they are away from home. This allows for a
higher setting and higher concentrations, which can be more effective for
purging purposes. The ozone will normally dissipate in less than an hour after
the purifier is turned off. Simple timers plug into an outlet and are available at
hardware and variety stores.

Install the O3plates in the plate receiver slot (see diagram on
previous page)
Start with the Air Purifier on its lowest O3setting and turn the O3
dial “up” as necessary. The ideal amount of O3will leave your
room smelling clean and fresh. If the unit is set too high, you will
smell too much O3. If it is set too low, you will smell household
odors.
The Ionizer is designed to run independently from the O3
production. The ionizer can be used around the clock to keep
down dust and particulate. O3, however, should be kept at modest
levels in occupied spaces. O3primary application is to control
odors. The level of O3may be adjusted according to the severity
of the odors in the home or office. The O3that is not used,
normally reverts back to O2in about an hour.
Individual sensitivity to O3 and preference may vary and should be
adjusted accordingly. The effect of O3 on indoor air may vary
according to atmospheric and/or environmental conditions such as
altitude, humidity, air movement, and severity of existing odors,
house design and square footage.
If you desire to treat the entire home, set the fan switch on your
home’s heating & cooling system to the ON position rather than
AUTO. Open all interior doors and adjust the O3 level to the
appropriate setting. Then place the unit so the air from the purifier
flows directly into an air return vent.
Altitude: Generally, in higher altitudes the requirement for
activated oxygen decreases. Therefore, higher altitudes should
require lower settings.
Humidity: Generally, in higher humidity the requirement for
activated oxygen increases. Therefore increased humidity may
require higher settings. High humidity will require additional
cleaning.
For optimal treatment of air in your designated area, your new air
purification unit should be placed in a central location (higher is
better). Your unit can be set on a tall piece of furniture. Allow three
inches between the back of your unit and the wall to allow proper
airflow. Fan speed is normally set in the medium range. The reason
for elevated placement of the unit is that O3is heavier than air.
Elevated placement allows for better circulation. It is suggested that
the purifier be placed in the room that is close to the primary source of
odor.
OPERATION / INSTALLATION
Warning: Excessive O3concentrations may cause mucous membrane or
respiratory irritation and can be harmful. If you smell ozone when you enter a room,
turn the O3 dial down to a lower setting.
