CLEANING
AvaLung Unit Care:
Clean the AvaLung unit after every three days of use and whenever it will be
stored for more than three days after being used. High-level disinfection is
required if an AvaLung is to be shared by different users.
to remove the AvaLung unit:
Open the pack's main compartment and completely unzip the two zippers that
give access to the AvaLung exhaust tube. Separate the hook and loop tabs and
remove the orange exhaust end connector from the orange exhaust manifold.
If necessary, pry the connector out with a flat screwdriver, being careful not to
damage the parts.
Rotate the valve box in the left
shoulder strap 90° so that it will
fit through the opening in the
back panel of the backpack. Pull
the valve box and inlet tubing
through the back panel and work
the mouthpiece through the
shoulder strap at the same time.
Do not remove the mesh cover
on the valve box during cleaning. (see illustration)
If you will be using the backpack without the AvaLung installed, place the
plug into the exhaust manifold.
To reinstall the AvaLung unit: Guide the mouthpiece through the shoulder
strap sleeve from inside the pack while pushing the black valve box through
the vertical slot in the back panel. With the valve box in place in the shoulder
strap, rotate it 90° so that the intake holes are facing the outside of the pack
and the mouthpiece opening faces the center. Thread the exhaust tubing
with the orange end connector through the zippered covers and insert the
exhaust end connector into the orange exhaust manifold – pushing it firmly
into the manifold until it snaps and locks in place. Zip the upper cover
closed, fasten the hook and loop tabs in the side pocket, position the tube
in the sleeve and zip the sleeve closed. Both the intake and exhaust tubing
should be fully compressed when reinstalled. Breath through the AvaLung,
checking that air comes out the exhaust port on the outside of the pack.
