Breathing bags
Fit the breathing bags onto the E 466 injector nozzle.

Make sure the opening of the breathing bag fits securely over the

plastic cone.
This will prevent the breathing bag from sticking together during the
cleaning and drying process.
The breathing bag is attached correctly when it cannot dislodge it-
self from the plastic cone.
Breathing masks
Remove the stopper from breathing masks which have a closable

air cushion. Expel as much air as possible and then replace the
stopper.
