CLEANING MR850 Heaterbase Using a damp cloth, clean the humidifier with either of the following: Isopropyl Alcohol, normal dishwashing detergent. Temperature  
Probe Always clean before use. Probes can be cleaned with one of the following solutions: SporicidinTM, CidexTM OPA, SporoxTM OR sterilize the probe using Ethylene Oxide  
sterilization at 55 °C (131 °F), 80 kPa, (allow at least 15 hours for residual ETO to disperse before use). Wipe the airway temperature probes clear of any cleaning residues  
before use. Store probes in clean conditions. DO NOT autoclave probes.  
CAUTION: DO NOT immerse the heaterbase or temperature probe electrical connections in any liquid.  
NOTE: Follow the cleaning agent manufacturers’ instructions carefully. It is the user’s responsibility to qualify any deviations from these procedures, both for disinfecting  
efficacy and physical effect on the probe and the heaterbase. See the MR850 technical manual for more detailed instructions on cleaning.

NON-HEATED BREATHING CIRCUITS  
SET UP  
Slide humidification chamber (a) onto humidifier base and  
connect breathing circuit (b) (refer to humidification chamber and  
1.  
breathing circuit operating instructions for further details).  
Connect the temperature probe plug (c) (REF 900MR86X) to the  
blue socket on the humidifier base until an audible click is heard.  
2.  
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.

Non-heated breathing circuit with MR290 Chamber  
900MR869 Temperature Probe, Mounting bracket to suit ventilator  
To set the humidifier to non-heater wire mode, refer to the MR850  
technical manual. (Rev. H or later).  
For all other applications refer to Product Guide or contact your local  
Fisher & Paykel Healthcare representative.  
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.

Temperature Control Settings (non heated circuits)  
Invasive Mode:  
Noninvasive Mode: Airway 31 ºC  
Airway 37 ºC  
The airway probe out test does not work with non-heated breathing  
circuits. A low humidity alarm will instead be given.  
Alarm Parameters (non heated circuits)  
When there is no gas flow the humidifier will give a low humidity  
alarm.  
High Temperature Alarm: Immediate, audible alarm at a displayed  
temperature > 41 ºC  
Low Temperature Alarm: Audible alarm at a displayed temperature  
< 29 ºC (Invasive), < 26 ºC (Noninvasive)  
Performance (non heated circuits)  
If the chamber runs dry either a water out alarm or a low humidity  
alarm will occur.  
Recommended Flow Range: Invasive Mode: 6 to 60 L/min  
Non-Invasive Mode: 6 to 120 L/min
