ing system
– APL valve is not firmly fixed to the breathing
system cover (damaged) or not set to 30 hPa
(cmH2O)
– Breathing bag, breathing hoses, Y-piece, or mi-
crobial filter not connected correctly or dam-
aged
– Flexible arm for breathing bag (optional) not fit-
ted correctly on the breathing system, sealing

the connections)
– Connections for the sample line for gas meas-
urement cracked or defective
– O-ring of the inspiratory and expiratory ports
missing, soiled, or damaged

2 sensor not (or not correctly) connected (for
electrochemical O2 measurement only)
– Breathing system cover not mounted correctly,
not all five sealing screws closed
– Visible damage on valves or seals of the breath-
ing system metal valve plate
– Breathing system not mounted correctly, not all
three sealing screws closed

missing or handwheel not set to 0.
Proposals on how to systematically rule
out components when looking for leaks
Carry out the described measures and perform or
continue the leak test:
Exclude the sample line for gas measurement
from the leak test
z Remove the sample line for gas measurement
and seal the Luer Lock connection on the
Y-piece.
Exclude the breathing hoses from the leak test
z Disconnect the breathing hoses from the
breathing system. Connect the inspiratory and
expiratory ports with a hose that does not leak.
Connect the breathing bag directly to the
breathing system.
Exclude the vaporizers from the leak test
z Remove the vaporizers from the workstation.
NOTE
Possible cause of leaks:
The vaporizer is not connected properly or the fill-
ing device is open.
