Warnings and safety instructions
Safety notes
Please read this manual carefully before using this product and save it for future reference. Do not use this
product without fully reading and understanding these instructions. Injury or damage may result.
If you cannot understand this user manual, please contact your service provider or after-sales service center.
SCALEO Medical provides consulting and training services. Make sure that the user understands this user
manual and uses this product accordingly.
Users of home oxygen therapy should strictly follow the doctor's prescription. Oxygen therapy is performed
according to the doctor's daily oxygen flow and oxygen inhalation at rest, sleep and during exercise. It is
strictly forbidden to adjust the oxygen flow rate and adjust the time by yourself, in order to avoid insufficient
oxygen supply or oxygen poisoning.
Patients who are in urgent need of oxygen, critically ill patients and patients under continuous oxygen
inhalation, shall have other oxygen supply devices (such as compressed oxygen cylinders or liquid oxygen
systems) as a backup product when using the Ho2rizon® S5 oxygen concentrator.
If an adverse reaction appears when inhaling oxygen, stop using it and contact your service provider or your
doctor immediately.
If there is an eventual device failure, contact your service provider or the manufacturer's after-sales service
center immediately and do not disassemble it or repair it.
This device is not intended to be life sustaining or life supporting. Additional monitoring or attention may be
required for pediatric patients, elderly patients or patients using this device who are unable to hear or see
alarms or communicate discomfort. This product is not suitable for babies.
Severe carbon monoxide poisoned patients are banned from using this device.
The nasal cannula is dedicated to one person and should be cleaned and replaced regularly. Be careful not to
adjust the flow meter float (middle part) beyond the red line position. Long-term use will reduce the
efficiency of the oxygen concentrator.
If the product has been stored for 6 months by the dealer, the product must be returned to the factory for
inspection.

DOMA119_v5_20200629_ Ho2rizon® S5 5
Warning
Please read the following information carefully before operating the oxygen concentrator.
Special attention should be given to reducing the risk of fire when using oxygen therapy. When the oxygen
concentration is high, any material becomes extremely flammable and burns quickly, regardless of whether it
is flammable or not. For safety reasons, all ignitions should be kept away from the oxygen concentrator and
preferably shall not be in the same room as the oxygen concentrator.
Oil, grease or petroleum-based products are prone to strong spontaneous combustion when exposed to
oxygen under pressure. These materials must be kept away from oxygen concentrators, piping, connections
and other oxygen concentrator components. Do not use any lubricant.
Oxygen concentrators are strictly prohibited from being inverted or positioned horizontally during use and
displacement, and should avoid an environment of pollution and smoke. The oxygen concentrator requires an
ambient temperature of 10 to 37°C. When the temperature is lower than 10°C, the compressor may have
difficulties starting. Above 37°C will cause the compressor to overheat and shorten the life of the machine.
It is strictly forbidden to use oxygen concentration in an environment above 3000 meters. Such an
environment will reduce the quality of patient treatment.
Please do not move the oxygen concentration while it is in use.Do not turn on the oxygen concentrator with
the flow meter turned off.During use, the oxygen concentrator produces a regular exhaust sound when
oxygen is produced, which is a normal phenomenon.It is normal for the exhaust vent at the bottom of the
oxygen concentrator to discharge hot air.
Please do not block the exhaust vent during use.In order to achieve the best performance of the oxygen
concentrator, SCALEO Medical recommends to use the oxygen concentrator for more than 30 minutes each
time. Frequent use of the oxygen concentrator for a short period of time may reduce the lifespan of the
machine.
If the oxygen compressor power cord or plug is damaged, if the machine is working abnormally or if it falls
into water, please contact your authorized service provider for inspection.Keep the power cord away from
heat or high temperature surfaces. Do not use extension cords.

Do not move the oxygen concentrator by dragging the power cord. Do not drop or insert foreign objects into
any openings. It is strictly forbidden to block the air inlet and exhaust port of the device or place the machine
on a soft surface, such as a sofa or a bed, which can cause the exhaust port to be blocked. Keep the air intake
away from plush, hair or similar.

When adding water into the humidifier, do so according to the amount calibrated by the
humidifier. Do not add excessive water.
Oxygen concentrator must be at least 40 cm away from walls, tapestries, furniture and similar objects.
The Ho2rizon® S5 medical oxygen concentrator is equipped with a set of oxygen nasal cannula. Patients can
also choose other anti-extrusion registered oxygen cannula to be purchased as needed. However, the length
of the nasal cannula should not exceed 14 meters. Oxygen nasal cannula should be placed correctly to avoid
the risk of wringing the head or neck.
Do not use parts, accessories, or equipments that are not approved by the manufacturer. The use of
unspecified humidifiers or other accessories may reduce the performance of this concentrator.
Do not connect the concentrator in parallel or series with other oxygen concentrators or oxygen therapy
devices.
Do not use any power cord other than the original. Non recommended power cords can cause increased
electromagnetic radiation or reduce electromagnetic immunity, resulting in operational failure.
Oxygen therapy is harmful under certain conditions. SCALEO Medical recommends the use of the Ho2rizon®
S5 oxygen concentrator under medical prescription only. Oxygen therapy should be performed according to
the prescription of the doctor. Unauthorized adjustment of oxygen flow is strictly prohibited as it may cause
oxygen poisoning or carbon dioxide retention. This medical device is designed to supplement oxygen, not for
first aid or sustain life.
Avoid creating sparks near medical oxygen equipment, including static sparks generated by friction.
If the oxygen concentrator is used under abnormal conditions for a long time (in terms of humidity,
temperature, dust... outside of its normal range) this will reduce its efficiency. Please contact your service
provider or the after-sales service of the manufacturer.
Regularly evaluate your treatment and contact your doctor if you have uncomfortable symptoms when using
this device.
Maintenance
The Ho2rizon® S5 oxygen concentrator is designed to minimize the number of maintenance routine. The
maintenance period is approximately once a year. Only an authorized after sales service can disassemble,
repair or commission the equipment.
