overheat.
●Do not use accessories or parts that are not recommended or configured. Incompatible accessories or
accessories can cause performance degradation or affect the EMC performance of the device.
●Condensation may damage the device. If the device is exposed to extremely hot or cold temperatures, the
device should be adjusted to room temperature (working temperature) before starting treatment. Do not use the
device in a temperature environment outside the operating temperature range indicated in the parameters.
●Do not use this device when the room temperature exceeds 35°C (95°F). When the room temperature exceeds
35°C (95°F), the air temperature in the duct may exceed 43°C (109°F). Thereby causing irritation or injury to
the respiratory tract.
●Do not use this device under direct sunlight or near heating device, as these conditions will increase the
temperature of the output airflow of the device.
●If the environment or power supply exceeds the specification range, it may cause automatic shutdown or the
ventilation control cannot meet the specifications.
●When you use this device in a home environment, you need to place this device away from pets and children.
●Please check if there is water in the device before use. The maximum water level limit of the water tank is
260ml.
●Before use, please confirm that the tubing is properly connected and avoid the risk of neck winding caused by
the use of breathing tubing and hoses. Check the pipeline for damage or wear, and replace the pipeline if
necessary.
●The patient is the intended operator. The patient can safely use the treatment function of the device. When the
patient is using it, the parts of the device cannot be maintained or repaired.
●When using oxygen, the oxygen supply must comply with local standards for medical oxygen. It is forbidden
to connect the device to an uncalibrated or high-pressure oxygen source. Please do not use oxygen when you
smoke or have an open flame to avoid burning. The distance between the device and the oxygen source should
be at least 1m to avoid fire and burns.
●When using oxygen, please turn on the machine before turning on the oxygen. Turn off the oxygen before
turning off the machine. Prevent oxygen from accumulating in the machine. Warning explanation: When the
machine is not working and the oxygen is still on, the oxygen transmitted to the hose can accumulate in the
machine casing. The oxygen accumulated in the machine casing poses a fire hazard. Do not connect this device
to an uncontrolled or high-pressure oxygen source.
●Incorrect use of masks or accessories may cause the CO2 concentration to increase to a critical value or allow
unconscious breathing, which may cause breathing suffocation.
●Do not block the exhaust port of the mask. If you are using a full face mask (the mask covers your mouth and
nose), the mask must be equipped with a safety (entrainment) valve.
● Repairs, services and maintenance should only be performed by the manufacturer or technicians expressly
