Troubleshooting
The following applies only for the electronically controlled gas mixer:
If the central supply for a gas fails and no sufficiently filled gas cylinder is
connected, (see "Gas mixing unit (electronically controlled)", page 36), the device
automatically uses a substitute gas:
The level of the fresh-gas flow is maintained.
12.3.2 Failure of one gas
Operation of fresh-gas delivery is still possible when supply of one gas fails. If, e.g.,
N
2O fails, proceed as follows:
Electronically controlled gas mixer:
● Switch to Air or O
2 as the carrier gas.
Mechanically controlled gas mixer:
● Open the appropriate flow control valve for the substitute gas.
If the O
2 supply fails, delivery of N2O is not possible. For further information see:
"Minimum O
2 delivery (SORC)", page 324.
12.3.3 Replacing an empty gas cylinder
1. Close the valve of the empty gas cylinder.
2. Completely use up or completely release any gas remaining in the pressure
reducer and in the hose between the device and the gas cylinder.
If there is no patient connected, venting can be performed as follows:
– Disconnect the central O
2 supply.
– Open the flow control valve of the O
2 flowmeter. Wait until gas is no longer
flowing.
– Close the flow control valve of the O
2 flowmeter again.
3. Unscrew the pressure reducer from the gas cylinder valve.
4. Replace the gas cylinder with a full gas cylinder.
5. Connect the pressure reducer to the new filled gas cylinder, see page 76.
6. Open the valve of the filled gas cylinder slowly.
