Sampling gas inlet
6 - 10
Test case 3.4
1. Connect the leakage detector to the Auxiliary
fresh gas outlet. Make sure that the valve is open.
2. Plug the Fresh gas valve connection on the
Inspiratory gas block.
3. Pressurize to 40–50 cmH
4. The following parts are checked during this test
case:
• Fitting including OV4.
• SV4 (14 kPa).
• Tube including fittings between the Inspiratory
gas block and the Instant O2 Supply block.
• SV8 (-3.5 kPa) including silicone rubber muff.
• Tube between SV8 and the Auxiliary fresh gas
outlet valve.
• Auxiliary fresh gas outlet valve.
Test case 4: Multigas analyzer line
1. Bypass the multigas analyzer:
• Remove the multigas sampling line adapter
from the Y-piece.
• Block the sampling gas inlet on the patient
cassette, e.g. by covering the hole with a piece
of adhesive tape.
2. Redo the PuC.
Note: After the "Leakage automatic ventilation"
or the "Leakage manual ventilation" test is done,
cancel the PuC and remove the tape to prevent
pump damages.
3. If "Leakage automatic ventilation" test passes,
the malfunction was located to the multigas
analyzer line. Check the following parts:
• Sampling line adapter.
• Sampling line.
• Water trap.
• Water trap receptacle including seals.
• Tubes between the water trap receptacle and
the multigas analyzer.
• Multigas analyzer. For leakage checks, refer to
the service manual for the concerned multigas
analyzer.
• Multigas analyzer return gas tube including the
Docking station silicone muff.
