OPERATION

2.Unscrew the valve cap from the keel air chamber valve by turning a quarter of a turn counterclockwise. Make sure the valve stem is in the closed position. Attach the air hose adapter to the air valve. Inflate the keel to the recommended air pressure of 0.25 bar (3.6 psi).

3.After inflation, install the valve caps tight (turn clockwise).

NOTE: Always be aware of the air pressure in the air chambers. The air volume inside the air chambers will expand as the internal air temperature rises; this will cause the air pressure to fluctuate depending on water temperature and weather conditions. A boat that is correctly inflated, may experience a drop in air pressure and require additional air when temperatures decrease; or it may become over inflated when in direct sunlight or as the temperatures increase. This will require the air chamber to be deflated until the recommended air pressure is reached.

Overpressure Security Valve ‑ Hypalon Models

NOTE: This feature is Included on Hypalon fabric models.

If the air pressure exceeds the maximum limit, the red cap will loosen or pop off the overpressure valve. Air will escape until the air pressure returns to the recommended limit. Replace the red cap on the overpressure valve.

NOTE: Keep items clear of the overpressure valve that could prevent the red cap from popping off the valve.
