Page 10: Notes To The Reader / Warnings
Notes to the reader / Warnings → Home care water chamber When using the Home care water chamber, fill clean water or medical sterile water (e.g. ALLEGRA sterile water) into the water chamber. By heating the water to 100°C before use, you reduce limescale deposits in the water chamber. - Page 11 → Connecting the oxygen source LM Flow (Fig.III a) The LM Flow high-flow device can be con- nected to a low-pressure oxygen source (e.g. oxygen concentrator). To do this, plug the oxygen supply hose onto the oxygen connector on the high-flow device (see Figure IIIa).

- Page 17 Caution: If the high-flow device sends an alarm because the set flow value is not reached, this may be because the nasal cannula model is not suit- able. In this case, it must be replaced with a larger nasal cannula. It is recommended that the NAS-1 S model be used when the flow is less than 50 L / min or the NAC-1 M model when the flow is less than 60 L / min.
- Page 18 The FiO2 can be controlled automatically when using the LM Flow 100. The oxygen concentration must be within the preset range of the alarm parameters for the oxygen concentration, otherwise an alarm will sound.

Drying Tube nasal cannula during the drying mode. Alarms The high-fl ow devices of the LM Flow series are equipped with visual and acoustic alarm signals. The visual alarm signal appears if an alarm is triggered while using the high-fl ow device. The causes of alarm signals should be eliminated as soon as possible in order to avoid risks. - Page 20 The following alarms are arranged according to internal priority: Problem description Alarm Modus operandi Problem description Internal alarm Turn off and turn on again. If After commissioning, an error alarm this does not solve the problem, displays errors in internal parts such please contact Löwenstein as the engine, and after 5 seconds Medical.

Page 22: Cleaning And Maintenance
Cleaning and maintenance The high-flow devices of the LM Flow series humidify the respiratory ther- apy gas with water vapor. If the regular cleaning, disinfection and replace- ment of parts are not carried out in accordance with these instructions, there is a risk that bacteria will settle on and in the high-flow device, which can infect the patient. -
