1) Manual Inflation
Activate the inflation system by jerking firmly downward on the pull-
tab (Fig. 4). The Inflatable PFD should fully inflate within 5 seconds.
Automatic Inflator

2) Automatic Backup Inflation
When the inflator is lowered more than about 4 inches in the water,
then the hydrostatic valve opens and lets the water meet the water
sensitive element that in turn releases a stainless steel coil spring.
The spring then drives a needle into the end of the gas cylinder,
which is now punctured so that the gas instantly fills the life jacket.
Total buoyancy is normally reached within 4 – 5 seconds.
Information
When inflated, the carbon dioxide (CO
2
gas) used to inflate the PFD
will slowly escape through the fabric over time. A slight reduction
of pressure will be observed after several hours of inflation. Topping
up by oral inflation may be required in the event of very prolonged
immersion.

3) Oral Inflation
Properly armed and inspected Inflatable PFDs will inflate when
manually or automatically activated. However, you can fully inflate
the Inflatable PFD by mouth (Fig. 5) should inflation not occur, or if
you are in a non-emergency situation.
i. To orally inflate the Inflatable PFD, first ensure that each of the
zippers (2) are completely opened.
