2) For devices where the CO
2
cylinder is accessible, remove the CO
2
cylinder,
to prevent inadvertent activation of the manual ination system which could potentially
damage the otation device. Inspect the threaded end to conrm that it has not been
pierced and is unused.
3) Put on the otation device. Locate and release the oral tube from its cover.
4) Get into shallow water, just deep enough that you can stand with your
head above the surface.
5) To learn how much ination is needed to oat you, blow a full breath into the oral tube
and then try lifting your feet from the bottom to see if your airway stays clear of the
water. If not, try adding another breath and lifting your feet, and then another if
needed and so forth so that you are supported well enough to be able to complete
ination without touching bottom or treading water. There may be situations where
you wish to wear your device partially inated such as activities or conditions in which
accidental ination would present a signicant risk. The device must be fully inated to
function as designed and approved.
6) Remember as your breath air cools down it contracts in volume. You may require more
topping up breaths to maintain this level. This level of ination may also be useful in
cold conditions where ination could be delayed.
7) Then see if the turning characteristics of the PFD are different with this level of
otation, as it most likely will be.
8) Fully inate the otation device using the oral inator.
9) See if the otation device will oat you on your back or just slightly back of
vertical. In a relaxed oating position, verify that your mouth is well above the water’s
surface. Note the effect of where you hold your legs on how you oat.
10) Get out of the water and remove the otation device. Completely deate the otation
device using the oral inator.
11) Let the otation device dry thoroughly. REARM AND REPACK the otation device in
accordance with the manufacturer’s instructions!
