Fresh-gas delivery (version for 3 gases)
The total flow tube and the pressure gauge are
located on the front of the device below the screen.
There are 2 flow control valves for Air and O
2 on
the gas mixer for 2 gases. There is a third flow
control valve for N
2O on the gas mixer for 3 gases.
All flow control valves are labeled and provided
with a color coding, see chapter ''Color coding for
anesthetic agents and medical gases'' on page 51.
The O2 flow control valve is additionally provided
with grooves on the gripping surface.
A Total flow tube that displays the sum of the
individual flows of all used gases (O

*
L LED warning indicator for low O2 pressure
If the pressure drops below 20 psi (1.4 kPa x100),
the LED warning indicator lights up.
The displayed fresh-gas flow is in the range
between 0 L/min and 12 L/min.
– If the value of the fresh-gas flow is higher than
12 L/min, the electronic fresh-gas flow display
flashes (B, C, D).
– The field for electronic fresh-gas flow display
shows "+".
