Troubleshooting
4.3 During use
1. Open the cylinder valve. The pressure gauge shows the
cylinder pressure of the device cylinder.
2. Put on connected masks.
3. The residual pressure warning whistle sounds from a
residual pressure of approx. 50 bar in the connected
device cylinder.
4.4 After use
1. Take off the mask.
2. Only close the cylinder valve when no more breathing air is
required.
3. Vent the lines via the lung demand valve.
4. Dismantle the pressure reducer unit from the device
cylinder.
5. Replace the used device cylinder with a completely filled
device cylinder.
6. Refit the pressure reducer unit onto the new device
cylinder.
7. Disconnect the PPE and replace it with cleaned and
disinfected PPE.
