SAFETY FEATURES
The following safety features must be observed during device’s
use, operation and maintenance. Failure to comply with the safety
features in this manual may cause serious damage of the device,
its parts or accessories.
Do not use the device in explosive environment
Do not power up the device in the environment with flammable
gases and smokes. Do not use any electronic devices in such
environment due to the possible danger of explosion.
Water, humidit and heat
Do not use the device near water or in a high humidity
atmosphere, where condensation of water may occur inside the
device. Do not expose the device to rain. It can cause an electric
shock or a fire! Never install the device near a source of heat or
hot air. During installation, ensure that there is an access of air to
the device and the ventilation openings are not covered.
Powering up the device
To power up the device, use the original power cable. Wait for at
least 10 minutes after unpacking until the device’s temperature
adjusts to the temperature of the environment. The purifier is
protected with safety class 1 with IP20 protection. Operating
personnel must be informed about the characteristics and the
impact of the UV C ultraviolet radiation on the human being.

1. Air disinfection - use
The Air Purifier is designed for disinfection of interiors such as
hospitals, doctors’ and vets’ practices, cleaning rooms, offices
with or without AC units, food processing factories, storage rooms
and public places with frequent movement of persons. The
disinfection is achieved by forced air circulation through the
chamber with UV discharge lamps. The device is designed the
way that the radiation does not get out of the discharge lamp
chamber. So called germicidal radiation, that is ultraviolet radiation
of the UV C spectrum with a wavelength below 320 nm, is used
for disinfection. Air disinfection is accomplished by performing of
this spectrum on microorganisms that are present in the air. It is
used everywhere, where the disinfection of the environment using
ordinary methods is not possible.
2. Air purifier installation
During air purifier installation, consider natural air circulation in a
room and place it the way that there are no barriers around, which
would block getting sufficient amount of air circulation. Air purifier
can be installed on the wall with two screws introduced through
holes on the rear side. Second option is an installation on the
stand with four supplied screws. In this case, you can easily put
air purifier on the table or other surface. For stand installation, a
PH1 screwdriver is needed.

3. Microprocessor control unit description, LED and RESET
Air purifier is equipped with a
microprocessor control unit, which
manages correct operation of the
whole device, air circulation and
calculates runtime of the discharge
lamps. On the side, there are OK and
SERVICE LED indicators, RESET
button and the main switch. After
turning on the main switch, fans will
start running and the green OK LED
indicator will light up. This means that
the device is working correctly. Red
SERVICE LED indicator will start
flashing 500 hours before the
discharge lamp lifetime ends. After
the lifetime ends, the red LED will be
on permanently.
4. Replacing UV discharge lamp
You need to replace UV discharge lamps after their lifetime has
ended. Even though they seem to light with the same, standard
color, the intensity of the ultraviolet UV C element is significantly
lower.
It is possible to open the device only when it is disconnected from
the power source. Unscrew the top cover and remove it. Eject the
discharge lamp from its base and remove it from the holder. Install
new discharge lamps in the reverse order mentioned before. We
recommend original OSRAM tubes of type HNS – see specification
in the technical specifications section. When closing the device,
ensure that the cover fits the device’s body and there is no gap
that could cause UV radiation leakage. Counter must be reset
after the replacement. Turn on the main switch and hold the reset
button pressed for at least 5 seconds using a thin object. The red
SERVICE LED will switch off. Malfunctioning or broken tubes must
be disposed as electronic waste.

5. Maintenance
Air purifier requires regular maintenance. Remove the dust or
other dirt using non aggressive cleaning aid. For correct
functioning of the emitter it is necessary to keep the tube clean
and monitor its lifetime. If the emitter is not supplied with a
programmable time switch with runtime counter, an operation log
must be provided to keep track of the UV C supply status at all
times. In case of any doubts, its efficiency must be checked by
measuring the intensity of the UV radiation.
6. Prevention from harmful effects of the UV-C radiation
UV C radiation has harmful effect on a human being depending on
the intensity and the time of exposure. When it comes to a
contact with eye, radiation can cause conjunctivitis. UV C
radiation is aggressive and harmful for humans, animals and
plants.
7. Description of PURITEC® HNS® discharge lamp
OSRAM PURITEC® HNS® are low pressure discharge lamps, which
emit short wave ultraviolet radiation. They are very environmentally
friendly, and they are a great alternative to chemical cleaners. Their
radiation effectively destroys cells and it is perfect for high
effective cleaning of water, air and surfaces while eliminating the
necessity to use chemical cleaners.
Operational principle of an UV C discharge lamp:
UV C radiation has photolytic effect on the DNA of microorganisms
like bacteria, molds, yeasts and viruses causing them to be
incapable to replicate. Cleaning effect is achieved by light of a
wavelength under 320 nm, with optimal effect at 260 nm. HNS
germicidal discharge lamps emit UV light with a wavelength of 254
nm – that is approx. 85% of the optimal effect and are ozone free.

HNS® discharge lamps do not generate ozone:
Main lines of the mercury discharge spectrum appear at 254 nm
and 185 nm. Ultraviolet light with lower wavelength below 240 nm
creates ozone. Discharge lamp housing is made of fused quartz,
which eliminates radiation below 240 nm. The discharge lamp
emits radiation, which destroys microorganisms, but does not leak
radiation that generates ozone.
