WAV SportLine 480 Owner's Manual - Note
We recommend that you should buy a pressure indicator from your dealer. You can use it to make a fast
and efficient check of the pressure during inflation. If you do not have a pressure indicat or, stop inflating
when it becomes difficult to operate the foot pump, and when the boat becomes "hard" (you will be unable
to twist the cone ends).
The ambient temperature of air
and of water influenc es
the internal pressure in the boat
EXAMPLE: Your boat is exposed to direct sunlight on the beach (temperature =50°C) at a
recommended pressure of 170 mb. After putting your boat into cold water (t emperat ure =20°C),
the internal temperature and pressure of the buoyancy mechanisms will drop (up to 85 mb) and
YOU MUST REI NFLATE THEM until the pressure rises enough to compensate for the pressure lost
due to the temperature differences. Thus, it is perfectly normal for the pressure to drop at the end of the
day when the temperature drops.
EXAMPLE: Your boat is inflated at its recommended pressure (170 mb) at the beginning of the day (low
ambient temperature = 10°C). You boat will be exposed to direct sunlight later on the beach or on the deck o
a yacht (temperature = 50°C). The inside temperature in all internal compartments can then increase up to
70°C (particularly for dark buoyancy mechanisms). The pressure will then double (340mb). THEREFORE
YOU MUST DEFLATE THE BUOYANCY MECHANISMS at the recommended pressure.

Therefore, it is important to anticipate:
Temperat ure variations (particularly if there is a large variation between the beginning of the day and
the end of the day in hot regions). Check and adjust the pressure of inflat ed compartments by inflating
or deflating them. Check that the pressure remains within the recommended range between 180 mb
and 220 mb.
THE RISK OF UNDER-P RESS URE
NOTE
:
The boat must be correctly inflated to ensure good performance. The
pressure in the buoyancy mechanism s makes your boat rigid enough to
operate correctly. Under-inflation makes the buoyancy mechani sm s
undesirably flexible, which will cause stre sse s and wear.
RISK OF OV ERPRESSURE
WHEN YOUR BOAT IS OVER INFLATED, THE PRESSURE IS TOO HIGH FOR
THE INFLATABLE STRUCTURE, AND THERE IS A RISK OF TEARING THE
FABRIC
!
CAUTION
IN CASE OF OVERPRESSURE
SEMI BUILT-IN VALVE:
deflate by pressing on the spring button.
