Ensure that Invasive mode is set for patients that have bypassed airways.
Ensure maintenance of grounding integrity by connection to a "hospital grade" receptacle.
Always disconnect supply before servicing.
When mounting a humidifier adjacent to a patient ensure that the humidifier is always securely mounted and positioned lower than the patient.
The operation of high frequency surgical apparatus, shortwave or microwave equipment in the vicinity of the humidifier may adversely affect its function. If this occurs, the humidifier should be removed from the vicinity of such devices.
Ensure that both temperature probe sensors are correctly and securely fitted. Failure to do so may result in gas temperatures in excess of 41 °C being delivered to the patient.
Do not touch the glass tip of the chamber temperature probe during use. Keep black connectors dry at all times.
Visually inspect accessories for damage before use.
Normal operation can not be guaranteed if powered from a source other than a pure sine wave, such as a square wave inverter.
