INFLATION INSTRUCTIONS
See Pages 12 -14 for additional information on testing and inflating your
PFD.
1. Manual Inflation - To inflate, grasp the Jerk to Inflate tab and pull
sharply downward.
2. Oral Inflation - The Oral Tube is located on the wearer's left side.
Grasp the Oral Tube and bring to mouth. Blow air through the Oral
Tube until the Inflatable Chamber is firm. If the chamber becomes
soft due to CO2 permeance, Oral Inflation will be necessary to
maintain full buoyancy. Whenever you orally inflate the PFD it would
be a good practice to remove the CO2 cylinder prior to inflating.
3. Cold Inflation - Oral Inflation may be required in addition to manual
inflation if chamber is not firm due to cold temperatures at or below
40° F (4° C). Inflation time using CO2 gas will be longer at these
temperatures. See FREEZING TEMPERATURES on Page 9.
4. Other Inflation Precautions
• Caution: Do not fully inflate orally then manually inflate with the CO2
cylinder. Repeated CO2 inflation after oral inflation will damage the
PFD to the point that it will not hold air or float.
• Never inflate this PFD with a Pump or Air-Compressor.
• Permeation loss is greater when the device is inflated with CO2 than
with air, and earlier replenishment by means of the oral inflation
system will be necessary after several hours.
