Service procedures
Checking the fresh gas channels
14. If the leakage is below 1000 ml/min, the leakage
in the "fresh gas to vaporizer" and "fresh gas
from vaporizer" channels will now be checked
(gas channels between the gas modules and the
one-way valve OV4):
• The system is filled with the "leakage flow"
calculated above during 5 seconds.
• The pressure should now increase. If not, a
leakage is detected in these gas channels.
Technical error code 9909 will be displayed
and the check will Fail.
Diagnostic 261, Sub data ..26 B5.
15. Evacuates the system by opening all mushroom
valves and the PEEP valve.
16. The leakage (ml/min) is shown on the control
panel and on the KION Monitor
• If the leakage is below 150 ml/min, the
leakage is accepted and next check will start
automatically.
• If the leakage exceeds 150 ml/min, the test
will Fail and the PuC will be paused. The user
can select Redo Test to repeat the check or
5
Continue to proceed with next check.
Diagnostic 262.
Technical error codes if the PuC fails
• A technical error code may be shown on the KION
Monitor and on the control panel.
• The failure will also be shown in the Diagnostic Log
and the CPS/IDS Diagnostic Log.

Leakage manual ventilation
Checking the patient unit
1. All mushroom valves in the patient cassette are
opened. In this way, the complete system is
checked.
2. The test is performed like in automatic ventilation
but the max. measuring period is extended from
20 to 50 s. The start pressure is 25 cmH2O since
most manual breathing bags are very elastic and
thus 41 cmH2O can never be reached.
3. If a leakage is detected:
• If the leakage is below 150 ml/min, the
leakage is accepted and next check starts
automatically. The leakage (ml/min) is shown
on the control panel and on the KION Monitor.
• If the leakage exceeds 150 ml/min, the test
will Fail and the PuC will be paused. The user
can select Redo Test to repeat the check or
Continue to proceed with next check. The
leakage (ml/min) is shown on the control
panel and on the KION Monitor.
Diagnostic 264.
• If the leakage exceeds 6 l/min, the test will
Fail and the PuC will be paused. The user can
select Redo Test to repeat the check or
Continue to proceed with next check.
A Technical error code is shown on the
control panel and on the KION Monitor.
Diagnostic 263.
Technical error codes if the PuC fails
• A technical error code may be shown on the KION
Monitor and on the control panel.
• The failure will also be shown in the Diagnostic Log
and the CPS/IDS Diagnostic Log.
