Safety measures for indoor-operations
The national relevant guidelines for operation with ozone must be followed. Ozone is a toxic
oxidizing agent and proves to be hazardous and harmful to the health. There are certain safety
measures that must be followed to avoid an uncontrolled release of the gas.
CAUTION: Ozone cannot be inhaled! It causes a reduced lung efficiency, which can continue for
several days!
Safety measures and equipment:
Wear masks with ozone filters, which cover the eyes, mouth and nose.
The treated rooms must have a sufficient supply of fresh air and a sufficient air exhaust.
Seek immediate medical attention in the following cases:
Inflammation of the eye, feeling of dizziness and extensive tussive irritation.
Dyspnoe and pain during inhalation.
3 Specified Application
The device is designed for neutralization of smells and the disinfection indoors by the fission of
molecules and cells by means of ozone. The ozone is generated by the device itself and emitted
through the air blower. The device was designed to neutralize smells in industrial and commercial
areas. The operation conditions for this device are an air temperature of +10 to +40 °C and a relative
air humidity of max. 80 %.

4 Operation mechanism
The device is a high-performance ozone generator designed to neutralize smells and to disinfect the
air. Ozone is the strongest oxidant used for disinfection. It reacts quickly with most of organic
substances. Therefore the relevant molecules are split. Thus it demolishes smells in kitchens, of
fustiness, urine and others, such as cigarette and burning smell. The purification method is similar to
air clarification in nature and during storms. The device follows most recent European guidelines and
safety regulations.
The ozone is generated through electrical discharge (Corona discharge) on the patented “Ceramic
Dielectric Electrode”, otherwise known as the plasma discharge plate. Due to high potentials the
“Ceramic Dielectric Electrode” generates high electrical field strengths, which leads to many short
barrier discharges between the electrodes.
An integrated air blower sucks the surrounding air at one side of the device into the device, leads it
through the “Ceramic Dielectric Electrode” and then gives out the ozone containing air back into the
surrounding air.
The ozone in this device is generated without the help of any further chemicals or utilities. It only
uses electrical energy and surrounding air. Thus it causes no environmental pollution. After the
device is switched off again, the remaining ozone dissociates after some time into Oxygen again.
5 How to set up the device
If you set-up the device, consider not to block the inlet and outlet for the air blower, so that the
device can easily suck in the surrounding air at the back of the device whilst releasing it at the other
side through its ventilation slots.
The idea location for a set-up in order to assure an ideal air circulation within the room, is the centre
of the room with an elevation of 2/3 of the rooms total height (e.g. on a ladder). The power supply of
the ozone air cleaner can be maintained via an adapter. For additional safety the adapter should be
plugged into a power jack that is outside the treated room. Thus the generator can be shut down
without actually entering the treated room.
As an alternative the device can be installed permanently on walls and other adequate vertical
surfaces.
CAUTION: Please follow the safety regulations for the operation on ozone generators indoors.

6.1 Turn on device
Press main “POWER”- button at the front of device. The LED above that button will be red. Now the
device operates in standby mode and can be programmed via its remote control (advised) or its
control panel.
6.2 Start operation
To start the device, press the “Air Fan” – button or the “step II / ON” – button on the remote control.
Now you will be hearing a confirmation tone. Now the LED of the timer will be shining from 2 h to 15
minutes (LED test), as well as the LEDs from the air fan on level I to level III. You will hear a
confirmation tone again.
6.3 Select operation time
By pressing the timer button you can chose the following operation times: 15 minutes, 30 minutes, 1
hour, 2 hours. By pressing the timer button you can jump between these options and the selected
option will be indicated through the LED lights and a logging beep. After the time is up, the device
will automatically switch into Standby mode. On the remote control each time period has its own
button, so you can directly chose the relevant time.
6.4 Select performance level of air fan
Similar to the operation time you can also chose the performance level of the air fan from three
levels. Each alternation will be indicated through a beep tone and by the LED lights. Even here you
can chose the relevant air fan level directly on the remote control.
6.5 Shut down operation program
All programs can be immediately shut down via the OFF-switch (red button on remote control). After
pressing it, the device immediately switches into Standby mode and can be programmed again.
7 Initiation
Check prior to every initiation whether the inlet and outlet for the air fain has no foreign matter in it
and whether the air fan has no contaminants. Contaminated or blocked gutters have to be cleaned
out immediately. Therefore read chapter “Care and maintenance”.
7.1 Important notes prior to initiation
Follow the safety measures and safety regulations for an operation with the ozone generator
indoors. You have to leave the room immediately after initiating the ozone generator.
Perform the following safety measures before initiating the device:
All openings and entries have to be closed or sealed, so that the ozone cannot leak out from
the treated room and potentially lead to an inhalation of the ozone in rooms, where there is a
person. The ozone is toxic and might affect the health of any person that accesses the room,
where the ozone air cleaner is in operation and the cycle is not yet completed. In that case
there might be acute hazards of intoxication.
Install warning signs at every entry of the room that is being treated, to warn from entering
the room since there is toxic gas spread. The signs might contain the period, ending time or
any further information on the ozonisation.

Manual

7.2 Tips on determining the operation period
The treatment time depends on various factors, e.g.:
Type of smell
Intensity of smell
Size of the room and temperature
Time and intensity of impact
Composition of the material and source of smell
Spread of smell
If you treat a room that is not heated at the time, but will be heated again after treatment, it might
lead to a recurrence of the smell. Thus the room temperature should be kept during treatment
always a little higher than the operation temperature later on (approx.. +5 °C).
In case the smell reappears after the treatment, you might have chosen a much too short treatment
time or the room temperature might have been too low. Repeat the treatment by varying the room
temperature and the treatment time.
8 Shutdown
After the set time is run out, the device automatically switches into Standby mode, as mentioned
above.
The time the treated room needs until the ozone concentration in the air is back to its initial
non-toxic state, or reaches the MAK level of 0.1 ppm, depends on various factors like the air
humidity, the treated material, size of the room, period of treatment etc.
The treated rooms need to be checked on their ozone concentration by trained and
authorized personnel, before they become open for access again.
The mean half-life of ozone is 30 min., depending on temperature, air pressure, UV radiation
etc.
The following calculation can be followed for the determination of the time of regeneration:
If the air concentration is at the time t =0 at a level of 100 % (e.g. 20 ppm- high value!!), It will
be 50% after half an hour (10 ppm). After an hour it will be 25 % (5 ppm). After four hours it
will be only 0.4 %, which equals 0.078 ppm for a relatively high initial air concentration. The
MAK value is on 0.01 ppm. Thus the room can be accessed after four hours again.
Even after four hours we recommend to not access the room before it wasn’t thoroughly
aerated. The regeneration time can be even shortened by the aeration. Always aerate the
treated room afterwards. If the room must be accessed for aeration, wear an adequate
mask.
We recommend waiting at any case at least 4 hours before accessing the room again.

10 Transportation
The device has to be secured before transportation and protected from any kind of impact. Too
intense impacts might lead to damages at the electrode / Plasma discharge plate.
11 Care and maintenance
A regular care and maintenance of the device and following the operational instructions assure a
smooth operation and long lifetime of the device.
NOTE: The device must be shut down and disconnected from any power, before performing
any maintenance!
The interval between maintenances depends on the stress and operation frequency of the device.
Especially the “Ceramic Dielectric Electrode” requires regular maintenance since it is often covered
with contaminants.
To determine the necessary interval for maintenance, consider your operation frequency, and the
surrounding conditions, in which the device is operates. If it was a dusty and dirty surrounding or if it
is a renovation after fire, you should check whether the device requires any maintenance.
Dry and relatively clean environments, where the device was applied require a less frequent
maintenance of several months. The following criteria are relevant for the determination of the
maintenance interval:
If device operates several hours continuously
Several days a month (e.g. if the device is free for rent)
In heavily polluted environments (e.g. dust etc.)
In humid surroundings
The following signs indicate the necessity of maintenance and cleaning:
The ventilation noise is clearly louder than normal
The electrode is covered. This can be determined by the typical noise of the
electrode, when it generates ozone. If this noise has become quieter the
electrode might be covered by something.
The air filter is covered

Follow these steps to clean the device:
a. Pull the power plug of the device and open the silver cover at the front to clean out the
Plasma discharge electrode.
b. Underneath there is the plasma discharge electrode. The plasma plate does not necessarily
need to be demounted for cleaning. Check the electrode during cleaning on potential cracks
or fractures.
c. Begin cleaning the electrode with a damp cloth. If you use a dry cloth for cleaning, make sure it is
without any fluffs, since they might lead to damages on the electrode. Be careful not to damage
the electrode during cleaning.
d. Make sure the electrode is absolutely dry before operating again.
If you the electrode is much heavier polluted you might have to demount the electrode:
a. Loosen the electrode from its attachment, since they are only clipped in.
b. After demounting the plate it can be cleaned carefully under clear water with a mild soap
solution (e.g. dishwashing detergent).
c. The device can be remounted after it has fully dried.
