NON-HEATED BREATHING CIRCUITS SET UP

1.Slide humidification chamber (a) onto humidifier base and connect breathing circuit (b) (refer to humidification chamber and breathing circuit operating instructions for further details).

2.Connect the temperature probe plug (c) (REF 900MR86X) to the blue socket on the humidifier base until an audible click is heard.

3.Push the chamber probe (d) and airway probe (e) into the breathing circuit. Make sure the chamber probe is correctly located in its key-way and that both probes are pushed home. The probe lead can be restrained using breathing circuit clips.

4. The humidification system is now set up and ready for use. After power on, the humidifier will default to invasive mode.

ATTENTION: Refer to operating instructions which accompany each accessory.

(a)(d)(e)
(b)
(c)NOTE

To set the humidifier to non-heater wire mode, refer to the MR850 technical manual. (Rev. H or later).

If a heated breathing circuit is used while in non-heater wire mode the humidifier automatically changes to heater wire mode. To use non-heater wire mode again will require it to be manually set.

The airway probe out test does not work with non-heated breathing circuits. A low humidity alarm will instead be given.

When there is no gas flow the humidifier will give a low humidity alarm.

If the chamber runs dry either a water out alarm or a low humidity alarm will occur.
