1.3 Cautions
Do not wear the mask before the device is in use. Otherwise, it will cause rebreathing of
inhaled carbon dioxide. Under certain conditions, rebreathing of exhaled air over several
minutes may cause suffocation.
Do not use the device in the presence of a flammable anaesthetic mixture in combination
with oxygen or air, or in the presence of nitric oxide.
Keep away from toxic or hazardous steam during use.
The plug must be inserted to power in a vertical direction to ensure normal use.
Periodically (weekly recommended) inspect flexible cords, cables, and power supply devices
for damage or abrasion. If damaged, stop using the device and replace it with a new one.
To avoid electric shock, pull the plug off before cleaning the device.
Maintenance of the device can only be carried out by the professional maintenance
personnel authorized by Humana Medical Ltd.
Do not use this device if the room temperature is higher than 35°C, otherwise the
temperature of air flow may exceed 43°C, which may cause irritation or damage to your
airway.
Do not use this device in direct sunlight or near heating equipment, which may increase the
air temperature of the output to unsafe levels.
To avoid electrical shock, disconnect the power cord before cleaning. Do not immerse the
device in any kind of fluid.
When using this device, make sure the mask is positioned above the height of the host unit.
Failure to do so may cause any condensed water in the Tube to flow into the user’s nose,
creating the risk of possible suffocation.
Stop using this device and replace it with a new one if the humidifier is damaged.
Do not touch the heater plate after turning the device off. Let the heater plate cool off before
touching.
Be sure that the device is in a place that cannot be accessed or touched by children, who
could be entangled, injured, or strangled by the tube.
If you notice an unexplained change in the operation of the device, if the device sounds
strange or harsh, if the device and (or) its power supply has fallen or has been misused, if
the shell is damaged, or if the liquid flows into the device, do not continue using the device
and contact your healthcare professional.
If necessary, our company provides designated qualified technical maintenance or other
qualified technical personnel with necessary technical materials for maintenance, such as
circuit diagrams, component lists, legends, correction rules, etc.
Sources of oxygen must be located more than 1 m from the equipment to avoid the risk of
fire and burns.
Do not operate the device if the ambient temperature is beyond the operating temperature
range. If the device has been exposed to temperatures that is above or below the range of
operating temperature, the temperature of the device should be set to room temperature
before use.
Do not immerse the device in liquid of any kind. Do not let any liquid enter into the device or
into the filter near the air inlet.
The condensate water can damage this device. Make sure that the device returns to room
temperature before use.
Be sure that the filter is seated properly in the device to ensure normal operation.
Any tar from smoking cigarettes near the device will stop the device from working properly.
If any liquid splashes onto the heater plate, disconnect the power supply and do not use it
until the plate is completely dried.
Only use distilled or purified water in the water tank. If any other type of liquid is put in the
water tank, it may damage the humidifier and/or device, possibly endangering the health of
the user.
Do not exceed the maximum water level mark on the water tank.
Do not splash the water into the device when filling the water tank.
Do not tilt the device. Keep the device level in order to avoid water flowing back into the device.
