Pressure; Should An Overpressure Occur - Zodiac MEDLINE 5.8 Eignerhandbuch

PRESSURE

The tube has 5 compartments. Each one should be at a pressure of 240 mb / 3.4 PSI.
It is the buoyancy chamber's correct pressure.
The ambient temperature of the air or the
water proportionally influences the
pressure level inside the tube.
It is therefore important to be able to anticipate changes.
Check and adjust the pressure in the inflatable compartments (by inflating or deflating) in line with
temperature variations (especially when there are significant temperature variations between morning and
evening in areas that are particularly hot) and make sure that the pressure does not deviate from the
recommended pressure range (220 to 270 mb).
RISK OF PRESSURE LOSS
Example:
Your boat is exposed to bright sunlight on the beach (temperature = 50°C) at the recommended pressure level
(240 mb/3.4 PSI). When you put it in the water (temperature = 20°C), the temperature of the inflatable
compartments and the pressure inside them will fall in step (by up to 120 mb) and YOU WILL NEED TO REFLATE
to regain the millibars lost due to the difference in temperature between the ambient air and water.
It is normal to observe a drop in pressure at the end of the day when the outdoor temperature drops.
RISK OF OVERPRESSURE
Example:
Your boat is inflated to its recommended pressure (240 mb/3.4 PSI) at the start or the end of the day (low outside
temperature = 10°C). During the day, your boat is exposed to bright sunlight on the beach or on the deck of a
yacht (temperature = 50°C). Temperature inside the inflatable compartments will increase (up to 70°C) especially
with a dark colour buoyancy chamber, causing the pressure to double (480 mb). YOU WILL NEED TO DEFLATE to
return to the recommended pressure.
WARNING!
IF YOUR BOAT IS OVERINFLATED, THE PRESSURE WILL ABNORMALLY
WEAR THE INFLATABLE STRUCTURE WHICH MAY LEAD TO A BREACH
OF THE ASSEMBLY.
