OPERATION
26
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 get cooler or it may
become over inflated when in direct sun light or as the
temperatures get hotter. This will require the air 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.
