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 7.
4. OTHER INFLATION PRECAUTIONS
a. 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.
b. Never inflate this PFD with a Pump or
c. Permeation loss is greater when the device is inflated with C02 than with air, and that earlier replenishment by means of the oral inflation system will therefore be necessary after several hours.
F. DEFLATION INSTRUCTIONS
Depress Oral Valve (located inside end of Oral Tube) using the protec- tive cap or tab provided by inserting into the end of Oral Tube, see draw- ing. Gently compress air out of the inflatable chamber while depressing the Oral Valve.
Refer to the back inside cover for REPACKING INSTRUCTIONS.
DO NOT TWIST OR WRING INFLATABLE CHAMBER TO DEFLATE. If for any reason the Oral Valve remains open, depress it several times. If it does not release, discontinue use of this PFD and take it to a certified Repair Facility. In an emergency situation, hold thumb over the valve if it will not close.
