1. Notes for service technicians
The following service instructions are intended exclusively for qualified service personnel. To reduce the risk of danger
(electric shock, UV-C exposure, exposure to high ozone concentrations), persons without appropriate qualifications or
without appropriate training should not perform any servicing other than as described below.
When servicing this appliance, the service technician is exposed to dangerous UV-C radiation, high concentration of the
hazardous substance –ozone, and high voltage. The possible effects of exposure to these dangers and assistance in such
cases are described later in the manual. It is essential that you read this information before you start servicing. Before
starting service work, you should also read the safety data sheet (ozone) and the UV-C radiation safety data sheet.
All service work must be carried out in accordance with the instructions for service technicians.
The voltage inside the device is high and can cause an electric shock. This is especially true for the very high
voltage generated by the ozone generators. It is dangerous to touch any parts inside the device. In the
event of an injury, follow the first aid instructions on page 5 of this manual.
The device emits UV-C radiation hazardous to human health. Before servicing, make sure that the
fluorescent lamps do not emit UV-C radiation. Observe the general safety rules. Use protective measures
in accordance with this manual or the UV-C safety data sheet. In case of exposure to radiation, follow the
first aid instructions in this manual and the UV-C safety data sheet.
The device generates ozone, which is a dangerous substance, can lead to respiratory damage and
at very high concentrations is dangerous for human and animal life. When carrying out
maintenance work, do not put your face close to the ozone generator or inhale the ozone directly
from the generator. Observe the general safety rules. Use protective measures in accordance with
this manual or the ozone data sheet. In case of poisoning, follow the first aid instructions in this
manual or the ozone safety data sheet.

3. Important safety instructions
There are several warning stickers on the housing of the device, the contents of which are also presented below. It is
imperative that you comply with them! Failure to comply with the information contained therein may lead to a risk to the
health or life of the user or other persons, animals and living organisms, and may lead to the failure of the device.
High voltage inside the device is dangerous to human health. In case of electric shock with the parameters as in the
device, skin burns, muscle spasms, loss of consciousness and, in extreme cases, cardiac arrest can occur. Therefore, all
service work may only start after the unit has been disconnected from the power supply and may only be carried out by
qualified and properly trained personnel!
In the event of an electric shock, isolate the victim from the power source as soon as possible - turn off the fuses and then
unplug the plug from the electrical outlet. The second, but more risky way is to pull the victim away from the power source
with a wooden stick. Call an ambulance as soon as possible after the victim is isolated from the power supply. If the victim
is unconscious but breathing, circulation is maintained and spinal injury can be ruled out, the spine should be placed in a
lateral fixed position. If the victim is not breathing, artificial respiration must be performed and, if necessary, a heart
massage. If the victim has symptoms of concussion (pale, cold skin, sweat, chills, accelerated heart rate), place them in an
anti-shock position - on their back, with their legs raised.
Despite a specially designed disinfection channel and limiting switch protection (removing any of the air filters disconnects
the fluorescent lamps), there is always a minimal risk of UV-C radiation escaping outside the device due to improper use
of the product or the occurrence of an unforeseeable failure by the manufacturer. It is therefore necessary to read the
following information on the possible effects of UV-C exposure, first aid measures and protective equipment!
Fluorescent lamps inside the device emit UV-C radiation, which can cause negative effects on skin and eyes. The effects of
radiation exposure depend on the wavelength, the amount of radiation absorbed and the type of tissue exposed. The most
common symptom of skin exposure to this type of radiation is erythema (redness). The degree of redness and its course
depend on the size of the radiation and the wavelength of the radiation. A high dose of UV-C radiation can lead to skin
burns, which are manifested by painful swellings and blisters. Long-term exposure to radiation leads to unfavourable
changes in the epidermis: it accelerates the skin aging process and causes pre-cancer and neoplastic changes. Repeated
exposure of the skin to radiation, particularly high intensity, can cause excessive keratinization, which is a contributor to
the formation of cancers such as basal and squamous cell carcinoma and melanoma. UV-C radiation absorbed by the skin
can cause inflammation of the cornea, conjunctivitis, damage to the retina and cornea and can lead to photochemical

Sterylis VS Manual | 6
cataracts. The most common, acute symptom of eye exposure to UV-C radiation is inflammation of the cornea and
conjunctiva. Corneal inflammation manifests itself in photophobia, increased tearing, a feeling of a foreign body in the eye,
eyelid spasm, and sometimes visual impairment. The symptoms of inflammation appear after a period of concealment
lasting even less than 30 minutes, and the symptoms of inflammation disappear about 14 hours after exposure.
Radiation-induced conjunctivitis occurs after a latency period of 5 to 10 hours and is manifested by redness, itching,
burning and tearing. If a higher dose is used, the correct vision may be impaired. The symptoms disappear after 10 hours
to several days, depending on the exposure. For this reason, never open the device while the UV lamps are running!
Description of first aid measures:
General rules
All symptoms of exposure to UV-C radiation occur after the so-called
latency period lasting from several minutes to several hours.
Eyes
In case of slight symptoms of eye burn (slight pain, tearing, itching, redness):
avoid direct sunlight, cool your eyes (with a cloth dampened with cold water
or glasses with cooling gel). Do not scratch or rub your eyes. If you have
contact lenses, it is essential to remove them to prevent further irritation. An
appointment with an ophthalmologist is recommended.
In case of more serious symptoms (severe blinking pain, foreign body
impression in the eye) it is necessary to contact an ophthalmologist. Until an
ophthalmologist has given assistance, proceed as with lighter symptoms of
eye burns.
Skin
In case of slight burns, it is recommended to cool the skin with running water
or apply a cooling gel on the skin. Contact with a doctor is recommended.
In case of increased skin exposure to UV-C radiation, it is essential to consult
a doctor.
Personal protective equipment (UV-C radiation)
Skin protection
Laboratory apron or other laboratory skin
protective clothing
Hand protection
Nitrile gloves
Eye protection
Spectacles with side panels and UV400 marking,
protective goggles or full face shields. Filters in
the given protective measures must be marked at
least "3-1,2" (3rd part number, 1,2 degree of
protection). If glasses or goggles are used as eye
protection, cover the remaining skin of the face
with clothing.

The device is designed to sterilise rooms by generating ozone in a concentration that may pose a threat to the health and
life of humans and other living organisms. Despite the safety principles during the operation of the product as described in
the following chapters, it is essential to read the information below on possible effects of ozone and on first aid in case of
exposure to a hazardous concentration of the substance.
Ozone, due to its strong oxidizing effect, has an irritating effect on conjunctivitis and respiratory mucosa. This may result
in burning pains and redness of conjunctivitis, coughing, wheezing, difficulty in breathing, increased frequency and severity
of asthma attacks in people suffering from this disease, and increased ailments in people with coexisting respiratory and
cardiovascular diseases. In very high concentrations it is dangerous to live.
The effect of ozone on living organisms depending on concentration is shown in the table below (based on [6]):
Effect

The graph on the left shows very clearly
what effects ozone poisoning can have on
humans depending on their concentration
and exposure time. The graph shows:
asymptomatic area (at such
concentrations and such exposure times
there should be no symptoms of ozone
poisoning), non-toxic area (possible light,
life-threatening symptoms), transiently
toxic area (strong symptoms of poisoning
that will disappear after a certain time,
alone or after the victim's help),
permanently toxic area (very strong
symptoms lasting for the victim) and lethal
area (huge concentrations of ozone may
contribute to the death of the exposed
person).
It is essential that you read the first aid measures set out in the table below:
General rules
To avoid exposure to the negative effects of ozone poisoning, wear full face
and eye masks, protective gloves and protective clothing in accordance with
the table "Personal protective equipment".
Guidelines for first aid providers
Wear protective gloves, avoid contact with eyes. Wash your hands
thoroughly with water and soap after providing medical assistance
Inhalation
If the airways come into contact with too high a concentration of ozone,
leave the ozone room as soon as possible and go out into the fresh air or
take the injured person out into the fresh air. In the case of respiratory
difficulties, give the victim oxygen. If the injured person stops breathing,
CPR must be performed
Contact with eyes
Eyes exposed to too high a concentration of ozone should be rinsed with
water as soon as possible for about 15 minutes. If you have contact lenses,
remove them and rinse your eyes with water. Rinse with a continuous but
not very strong stream of water, keep eyelids wide open, move the eyeball
while rinsing
Contact with skin
Skin exposed to too high a concentration of ozone should be rinsed with
running water and washed with soap.
Swallowing
Is not possible
Always seek professional medical attention in cases of serious or persistent symptoms!
Information on special treatment:
- If necessary, provide the victim with oxygen.
- The victim’s circulation should be monitored.
- Show the doctor maintaining the safety data sheet (ozone)

Ozone sensor located on the inside the steriliser allows the current concentration of ozone in the room to be tested, so
that the controller can determine the required ozone time and control the individual ozone generators accordingly to
maintain the correct ozone concentration during sterilisation. The ozone sensor also transmits information to the
controller when the ozone concentration in the room becomes safe for the user. These are the reasons why the ozone
sensor, which is an integral part of the device, has to work properly and therefore must not be blocked by any foreign
objects and must be in full contact with the air in the ozoned room so that their indications are correct! Improper
measurements of the ozone sensor can lead to life-threatening and health-threatening effects as described in this
chapter. The ozone sensor is calibrated by the manufacturer.
CAUTION! The following gases can affect the ozone sensor indications to a very high degree: carbon monoxide, hydrogen
sulphide, nitrogen dioxide, sulfur dioxide, ethanol, nitric oxide (II), chlorine, n-heptane, ammonia, methane, hydrogen and
carbon dioxide.
Although the sterilisation of the room will not be completed before the ozone concentration of 0.1 ppm (completely safe
for humans) has been reached, the room must be absolutely ventilated for at least 30 minutes after sterilisation. This is to
bring the ozone level of the room to 100% safe. Please note that the ozone sensors installed in the steriliser may fail or
the user may undesirably set them off, thus interfering with their measurements. It should also be borne in mind that the
safe level of ozone is different for adults, different for children and different for animals. Ventilating the device will also
allow to get rid of any fog created during the ozone process (a natural phenomenon) and to get rid of the smell of ozone in
the room partially or completely.

Sterylis VS Manual | 10
The safe operation of the product is also related to the principles listed below:
The device may only be operated in sterilisation mode in a tightly closed room (no ozone may penetrate outside
the sterilised room). Therefore, make sure that all windows, doors and any other escape routes for ozone from the
room are tightly closed. Gaps around and under doors and ventilation grilles must be carefully sealed. The room
must be protected from access by third parties.
It is also forbidden to stay in rooms adjacent to the ozone room during the ozoning process. If the ozoned room is
not properly sealed, some ozone may penetrate into other rooms.
To protect the room from access by third parties, it is essential to place warning signs “WARNING! NO ENTRY!
STERILISATION IN PROGRESS". Place them in a clearly visible place. The signs are included in the package.
After starting the sterilisation mode, leave the room where the steriliser is operating as soon as possible. The time
to leave the room is 120 seconds from the start of the ozoning function, only after that time the ozone generators
start. It is forbidden to stay in the room during operation of the ozone generator without a full respiratory and eye
mask with a suitable absorber. It is recommended to use a protective mask according to PN-EN 136 with an
absorber according to PN-EN 14387, type NO P3. It is also recommended to use personal protective equipment
for the skin according to the table of personal protective equipment.
Smoking and the use of tools that cause a flame or spark is prohibited in an ozoned room.
In order to deactivate the sterilisation mode before the end of the process, one should enter the room wearing a
full respiratory and eye mask with a suitable absorber (in accordance with EN 136 and EN 14387 standards) and in
the skin protection equipment in accordance with the personal protective equipment table.
When the ozoning of the room is complete, it must be thoroughly ventilated for at least 30 minutes.
Ozone is a heavier gas than air, after switching off the circulating fan of the steriliser, STERYLIS tends to settle in
the recesses of the ground and migrate by the floor.
It is not recommended to sterilise rooms below ground level without mechanical ventilation.
It is forbidden to carry out the process of ozonisation by persons with olfactory disorders.
This equipment may only be used by children at least 16 years of age and by persons with reduced physical and
mental capabilities and those without experience and knowledge of the appliance, if supervision or instruction
regarding the use of the equipment is provided in a safe manner, so that the hazards are understandable. Children
should not play with the equipment. Children without supervision should not clean or maintain the equipment.
Moreover, the device should not be operated in places directly exposed to sunlight, with high humidity, in places where
chemicals are used and in rooms with very small cubic capacity. For the correct operation of the ozone sensors the device
must be used in an environment with the following parameters:
Temperature: -20 to 50˚C
Pressure: 900 to 1100 hPa
Do not clean the room intended for ozone sterilisation with chlorine-based cleaning agents or other chlorinated
substances. This can cause erroneous indications of the ozone sensor in the device and expose the user to danger.
The device is equipped with a pre-filter and an active carbon filter. In addition, there is one additional pre-filter in the
package, which must be used interchangeably with the activated carbon filter when starting the sterilisation mode.
The manufacturer does not guarantee that the ozone sterilisation process (carried out in an appropriate manner) will not
