5.12 Ventilation with breathing system filters
(not supplied with the unit)
For hygiene purposes, and to condition the air for breathing, you can equip the patient valve
with commercially available filters (HME, bacterial or combined HME/bacterial filters) with
standard 15/22 mm connections. This increases both inspiratory and expiratory resistance.
Therefore you should monitor the ventilation pressure and volume with special care.
Allowance must be made for the larger dead space, especially with children.
Always follow the filter manufacturer's instructions for use.
5.13 Ending ventilation
Caution!
Never empty the oxygen cylinder completely. Always ensure that there is a certain
residual pressure in the cylinder when you return it for filling, since this prevents
moist ambient air from entering and causing corrosion.
1. Check the remaining oxygen content on the contents gauge of the pressure reducer. If
the contents gauge indicates 50 bar or less, the cylinder must be refilled or a reserve
cylinder obtained to ensure that the unit remains ready for use.
2. Close the valve on the oxygen cylinder.
Notice:
The unit still uses up electricity in standby mode. If the unit does not need to be used
for a long time or is not connected to the power supply, we recommend switching
it off completely. To do so, hold down the On/Standby/Off button until the LED alarm
goes out (approx. 10 seconds).

Notice
• Following the start of ventilation, all alarms are
automatically muted for 120 seconds. This is with
the exception of the technical alarms "Supply
pressure < 2.7 bar", "Battery almost empty", and
"Device malfunction", which cannot be muted.
During this time, visual alarms are still displayed.
• The acoustic alarm output is permanently muted in
NVG mode.
3. Hold down the On/Standby/Off button for 2 seconds to
switch the unit to standby.
