 Alternate means of ventilation must be available in case of power failure
or malfunction.
 Keep away from open flames, sparks and grease/oil. To avoid t e risk of
fire or explosion t is ventilator must not be used wit flammable gases
or anaest etic agents. Operating t e unit in a confined space will elevate
oxygen levels.
 T e ventilation setting will be interrupted during battery replacement
w ile t e device is in operational mode and t e external power supply is

 T e performance of t is ventilator may be affected if used around
portable and mobile RF telecommunication devices (cell p ones) wit in

 W en using a bacterial filter or HME (Heat Moisture Exc anger) connect
t e bacterial filter or HME to t e patient connection between t e elbow

 Use pressure regulators maintaining a minimum output flow of 120 L/min
at a dynamic pressure of 45 PSI to ensure t e proper functioning of t e
ventilator.
 Operation of t is ventilator outside t e environmental condition range
specified in t is manual may result in reduction and or failure in t e
ventilator’s performance. In extreme temperature conditions t e effect is
not noticeable in terms of delivered ventilations but may cause excessive
wear in ventilator or components over time. Extreme low temperature
reduces operation time of t e battery (Refer to 9.4 battery operating
Time).
 Operation of t is ventilator outside t e supply pressures range detailed in
t is manual may result in reduction in t e ventilator’s performance,
component failure, low pressure alarm or possible loss of automatic
