Connection procedures
Option 1 – Single circuit
1. Connect one end of the horizontally-ribbed tube firmly to the air
outlet, as shown in the Figure below :
Figure 12: Connection of single circuit to the device.
Now that your circuit is connected to the device, you can connect
the mask to the other end of the circuit.
Option 2 – Single circuit with expiratory valve and pressure line
(see illustrations overleaf)
1. Connect the air outlet firmly to one branch of the horizontally-
ribbed tube .
2. Then connect the expiratory valve tube (the only one fitted with
a white connector) into the valve control , then turn the
connector slightly to the right to make the connection secure.
3. Finally, connect the other tube (with no conne ctor fitted) to the
pressure line .
Note: Your circuit configuration may not include a pressure tap
tube, so this third step will not apply in your case.
