Changing the breathing circuit.
When replacing the breathing circuit with the same type of breathing circuit (heated-wire
being replaced with heated-wire), place the heater in pause mode before changing the
circuit. If replacing the breathing circuit with a different type of breathing circuit (Infant/Adult
or Heated-wire/Non-Heated wire), turn the humidifier OFF before changing the circuit. This
will allow the heater to auto-detect the new circuit without alarming.
Note:
The humidifier will give a heated-wire change alarm if PAUSE is exited and the
heated-wire configuration has been changed.
Note:
If the circuit type is changed the humidifier will revert to the remembered settings
the last time that circuit was used.
Warning:
Do not leave the humidifier ON, do not turn the humidifier ON and do not exit
the pause mode until there is regulated gas flow through the system. To do so may
result in heat buildup, causing a bolus of hot air to be delivered to the patient. Circuit
tubing may significantly soften under these conditions. Turn the humidifier power switch
OFF, or place the unit in pause and allow the system to cool before stopping gas flow.
8.
Removing From Service.
To turn the humidifier OFF
, press and hold the button until the display goes blank.
Allow the unit to cool before stopping gas flow.
Warning:
If the humidifier detects an internal problem during operation, the service icon
and the Priority Alarm Indicator will flash and an audible alarm will sound. If this hap-
pens, turn the humidifier OFF and let it cool. If the condition persists, take the unit out of
service and return to Teleflex Medical for servicing.
