4 Preparation and operation
4.11.2 Removing the oxygen supply
1. Close the valve on the oxygen cylinder.
2. Briefly press the On/Off button and operate the device
without an oxygen supply.
The remaining oxygen is flushed out of the device.
3. Press and hold the On/Off button for at least 2 seconds
to switch off the device.
4. Disconnect the low-pressure hose from the compressed gas
connection of the device.
5. If necessary: Replace the empty oxygen cylinder.
Result The device is disconnected from the oxygen supply.
4.11.3 Calculating the operating time
1. Calculating the oxygen level in the cylinder (oxygen supply):
2. Calculating the operating time:
100 % oxygen mode:
Oxygen supply = Volume of the oxygen cylinder x Pressure
in the oxygen cylinder
Example
Volume of the oxygen cylinder 10 l 2 l
Pressure in the oxygen cylinder 200 bar 200 bar
Oxygen level in the cylinder
(oxygen supply)
2000 l 400 l
Example
Oxygen supply 2000 l
Vt 500 ml
f 12 min
-1
Time
317 min = 5 h 17 min
or
31 min per liter of cylinder volume
Time (min)=
Oxygen supply (I)
Vt (l) x f (min
-1
) + 0.3 l/min
