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
connector slightly to the right to make the connection secure.
3. Finally, connect the other tube (with no connector 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.
