Place boat into its storage carrying case and secure the straps.
Inflation Specifications
The Wing CRRC Main Buoyancy Tube is rated for normal
operating pressure of 4.4 psi with ability to run up to 5.0 psi with
heavier loads. Each chamber is equipped with a Pressure Relief
Valve (PRV) to ensure over-inflation does not occur. However, over-inflation can occur if the PRV fails or is
intentionally blocked. Use the supplied pressure gauge to ensure each air chamber is properly inflated. Operating the
boat below the designed working pressure of 4.4 psi can cause performance issues and may damage the boat or pose a
safety risk to operators. To avoid risk, always operate the boat with the MBT and keel in the normal operating pressure
range.
Minimum inflation pressure:
CAUTION: DO NOT OVER-INFLATE!
WARNING: DO NOT UNDER-INFLATE MAIN BUOYANCY TUBE.
Proper inflation of MBT is critical for optimum boat performance.
Under-inflation can result in excessive tube flex, causing fabric stress and a shortened service life. Always
inflate to 4.4 psi or until PRVs release.
WARNING:
While inflating, do not leave inflation devices unattended! Pressure Release Valves (PRVs) may not
purge fast enough to prevent over-inflation. Over-inflation can cause tube rupture or catastrophic valve
failure, resulting in property damage, serious injury, and even death.
Pressure Relief Valves (PRVs)
PRVs are calibrated to release air at 4.7 – 5.0 psi and reseat at 4.4 psi.
While the main buoyancy tubes are rated at a recommended normal operating pressure, 4.4 psi (303 mbar), the inflation
limits of Polyurethane-coated polyester far exceed these recommendations.
Approaching these limits, catastrophic valve failure may occur before material failure resulting in flying metal pieces in
the vicinity of the boat.
