Propulsion System - Zodiac MEDLINE 500 Eignerhandbuch

Check and adjust the pressure of inflatable compartments (by inflating or deflating)
depending on the temperature (particularly when temperature variations are high
between the morning and evening in hot regions) and check that the pressure does not
leave the recommended pressure zone (from 220 to 270 mb / green zone).
LOW PRESSURE RISK:
Example: Your boat is exposed to direct sunlight on the beach (temperature=50 °C) at the
recommended pressure (240 mb/3.4 PSI). When you launch the boat (temperature = 20 °C), the
temperature and pressure in the inflatable compartments will jointly drop (up to 120 mb) and
you must then re-inflate them until the millibars lost due to the difference between air and
water temperature are regained. 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 beginning
or end of the day (low outside temperature = 10 °C). Later in the day, your boat is left in the
sun on the beach or on the deck of a boat (temperature = 50 °C). The temperature inside the
inflatable compartments may rise to 70 °C (particularly for dark buoyancy tubes), doubling the
initial pressure (480 mb). You must then deflate the boat 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.
CASES OF OVERPRESSURE
EASY PUSH valve:
Release air by pressing the
valve plunger
