Auto-Inflating the Boat
The Wing P-Series Auto-Inflation models use a unique cross-over valve system that allows the boat to be inflated with
compressed air or CO2 via two inflation valves located in the stern of the boat, port and starboard. The cross-over valves
allow air or CO2 to flow from one chamber to the next until the boat is fully inflated. Each cross-over valve can then be
closed, isolating each chamber and therefore minimizing loss of pressure should an individual chamber become
compromised.
1. Attach inflation cylinder.
Attach the inflation cylinder to the floor by placing it in the fabric cradle and
tightening the straps around the tank.
2. Attach Regulator.
Attach the regulator assembly with inflation hoses to the inflation cylinder.
3. Insert inflation hose fittings.
Insert inflation hose quick disconnect fittings into inflation valves on each side of
the boat.
4. Install the Auto-inflate keel hose.
Connect to the keel hose to the auto-inflate port on the keel in the bow. Hard deck
model in the floorboard cut out. Roll-Up floor model under the skirt flap. Then
attach the other end to the MBT fill port on the starboard side of the MBT. Open
the keel hose valve by turning the T-valve in line with the hose.
5. Open cross-over valves.
Open each cross-over valve by pulling and turning the knob clockwise ¼ turn.
“Ensure knob remains in the open (out) position”. This is done by “setting” the pin
into the notch.
6. Inflate.
Begin inflation by gradually turning the regulator valve until approximately one
turn is reached. The boat will inflate rapidly, as the MBTs progressively fill from
stern to bow, with the keel filling last. Continue inflation until the first PRV
releases. Turn the regulator valve to the off position. Allow the boat to equilibrate
to not waste air from the tank. Then, open the regulator valve again.
7. Begin to close regulator valve.
Gradually begin to close the regulator valve when all the PRVs begin to release air.
When this happens, close the valve completely.
8. Check MBT and Keel pressure to ensure they are at the minimum operating
pressure of 4.4 psi, adjust if necessary.
9. Close cross-over valves.
