Test case 3.1:
1. Connect the leakage detector to the vaporizer
magazine outlet connector (right connector).
2. Depress the vaporizer interlock.
3. Pressurize to 40–50 cmH
4. The following parts are checked during this test
case:
• Nozzle units at the fresh gas modules.
• Cuffs. Seals in the inspiratory gas block for the
fresh gas module connection.
• SV1 (600 kPa).
• Tube including fittings between Inspiratory gas
block and Vaporizer magazine.
• Small O-ring in the vaporizer magazine hub.
Test case 3.2:
1. Divide the Fresh gas line in two sections by
removing the fresh gas valve tube.
2. Visually check the fresh gas valve tube.
Test case 3.3
1. Plug the fresh gas flow transducer outlet at the
fresh gas valve.
2. Connect the leakage detector to the Vaporizer
magazine inlet connector (left connector).
3. Pressurize to 40–50 cmH
4. Test case 3.3 is an extension of Test case 3.1
and involves testing of parts according to 3.1,
plus the below listed items. Thus, if Test case 3.3
fails whereas Test case 3.1 passes, it points to a
defect or a leakage at any of the below items.
• Large O-ring in the vaporizer magazine hub.
• One-way valves OV9, OV10 and OV11.
Note: To check all three valves, the leakage
detector must be connected to two different
inlet connectors.
• Vaporizer selection valves 1, 2 and 3.
• Tube including fittings between Vaporizer
magazine and Fresh gas pressure container.
• Diaphragm inside Fresh gas pressure container.
• SV3 (18 kPa)
• Fresh gas flow transducer
• Silicone rubber connections (2 each) for the
flow transducer.
