8.2 Adjusting the oxygen volume flow

Fig. 25. Adjusting the volume flow
NOTE!
It may take up to 2 minutes until the actual volume flow corresponds with the setting. If
the output is closed, the output pressure can increase up to 0.35bar. The maximum
gas output temperature is maximum 6 degree higher than the ambient temperature.
NOTE!
After adjusting the oxygen flow setting, the alarms and status messages for oxygen
concentration and volume flow deviations are deactivated for approximately one minute
until the unit has reached a steady state. During this period alarms are muted.
ATTENTION!
The unit has been designed for operation at altitudes of up to 2000 m above seal
level. If the unit is used beyond this specification, compliance with the specified
performance data can no longer be guaranteed.
1 Press the adjustment regulator (1) for
at least 2 seconds.
– When a signal sounds and the volume
flow indication in the LC display flashes
the adjustment mode has been
activated.
2 Change the volume flow by turning
the adjustment regulator. Turning
clockwise increases the volume flow;
turning the regulator anti-clockwise
reduces the volume flow.
NOTE!
Perform the following steps to adjust:
0 - 2 l/min in steps of 0.1
2 - 4 l/min in steps of 0.2
4 - 6 l/min insteps of 0.5
3 The settings are accepted by pressing
the adjustment regulator again. The
input is once again acknowledged by
an audible signal.
NOTE!
The supplier may have restricted the
available volume flow range to
customized settings, such as 1 -4
lpm.
