10. The place can be occupied again once the ozonator finishes all the work phases. It will be
possible to notice this as it will no longer emit the sound signal, the LEDs inside will turn off and
you will no longer see their light coming out from the front panel. Furthermore, for the versions
with printer, the device will automatically issue the receipt in which the total time and the
maximum concentration peak reached in the ozonation phase will be reported.
WORKING METHOD OF THE DEVICE
The device is fully automatic and works in three consecutive phases:
1) OZONIZATION PHASE
The air present in the environment is passed through two electrically powered ceramic plates generating
the ozone molecules (O
3
) thanks to the action of the electric discharges on the oxygen molecules (O
2
)
present in the air.
The ozone generation stops or the plates turn off automatically when the saturation sensor detects an
average ozone concentration of 1 ppm.
ATTENTION:
IN THE ENVIRONMENT, THE CONCENTRATION OF OZONE ABOVE 1 PPM IS
DANGEROUS. PAY ATTENTION TO PERSONS AFFECTED BY ASTHMA, PULMONARY
DISEASES AND CHILDREN.
NOTE
: to stop the ozone generation at any time press the KEY 4 on the programming keyboard
The ozonation times
are indicatively the following:
FG 700/OZ53.5 and FG 702/O3.5 models
Up to 10 m
3
: maximum time about 2 minutes
Up to 25 m
3
: maximum time about 5 minutes
Up to 50 m
3
: maximum time about 10 minutes
NOTE:
the ozonation times shown are indicative and refer to place with a temperature of about 20°C and
relative humidity of about 50%. The concentration of ozone molecules in the place depends on many factors
such as humidity and temperature as well as on the quantity of objects and furnishings present in the place
to be treated (empty place requires shorter ozonation times than place the same size as for example
curtains, fabrics, etc. which immediately absorb a large part of the generated ozone molecules)
2) IGENIZATION PHASE
Once the generation plates have been turned off, the ozone molecules produced are left to act for 20
minutes. The ozone sensor remains active to verify that the average ozone concentration does not drop
below 1 ppm. When the sensor detects a concentration below 1 ppm, the device automatically reactivates
the ozone generation plates until the sensor detects a concentration equal to 1 ppm again. In this way, a
sanitation with an average of 1 ppm is ensured for the duration of the 20 minutes.
3) OZONE CATALIZATION PHASE
After 20 minutes of sanitization, the device starts the last phase in which the ozone that is dispersed in the
air is converted back to oxygen. The fans activate and suck the air present in the environment by passing
it through special particulate filters for further purification and subsequently, through a particular filter based
on activated carbon which has the function of converting the ozone into oxygen. This process lasts until the
ozone sensor detects an ozone concentration of 0.1 ppm such as to allow the operator, once the device
has automatically turned off, to enter the room and ventilate it for a few minutes in so as to further reduce
the amount of residual ozone.
