WARNING 
gassupply pressure meets hose requirements before usage. 
  Hose connectors adopt standardized gas terminal connector with gas nature. 
Different types of gas and gas with different pressures shall not be exchanged with 
each other. 
  Hose may be aging quickly by long-term exposure to acidity, alkalinity or 
ultraviolet rays. 
  Don’t cascade two or more hose assemblies together. 
  Do not block the air intake at the rear of the ventilator. 
  To prevent interrupted operation of the ventilator due to electromagnetic 
interference, avoid using the ventilator adjacent to or stack with other device. If 
adjacent or stacked use is necessary, verify the ventilator’s normal operation in the 
configuration in which it will be used. 
  To prevent possible personal injury and equipment damage, ensure that the 
ventilator is secured to the trolley or placed on the safe and smooth surface. 
  To prevent possible equipment damage, avoid tipping over the ventilator when 
crossing thresholds. 
  To prevent possible equipment damage, push the brake down when parking the 
ventilator. 
  Avoid the use of polluted air. When the equipment uses air as gas source for 
ventilation, if the air is polluted, harmful substance may enter the patient tubing   
  To prevent patient injury caused by equipment malfunction, when the alarm 
[Technical Error**] occurs, remove the equipment immediately, record failure 
code, and contact the Customer Service Department. 
  To prevent possible ventilator malfunction, do not spill liquid onto the ventilator.   
  A turbine can cause gas to be heated. To reduce the temperature of gas inside the 
tubing and prevent patient injury accordingly, ensure that the length of patient 
tubing from the humidifier to Y piece is greater than 1.2m. 
  The internal electrical power source is to be used if the integrity of the protective 
earth conductor or the protective grounding system in the installation is in doubt. 
  Nebulization or humidification can increase the resistance of breathing system 
filters, and that you need to monitor the filter frequently for increased resistance 
and blockage. 
  The ventilation accuracy can be affected by the gas added by use of a nebulizer. 
  The ventilator shall not be used with nitric oxide. 
  For non-invasive ventilation, the exhaled volume of the patient can differ from the 
measured exhaled volume due to leaks around the mask.
