BUOYANCY TUBE - PRESSURE
INFLATING THE BUOYANCY TUBE
•
Place the adapter corresponding to the diameter of the semi-built in valve at the inflation
pump hose nozzle.
Inflate the buoyancy tube,
balancing the pressure between the different compartments until
the partitions (a) are no longer visible (pressure = 240 mb)
Never put a compartment
under pressure while the
others are still fully
deflated.

Inflation is completed:
Screw on the inflation valve plugs.
NOTE:
A slight loss of air is normal before the cap is screwed on.
Only the plugs provide final airtightness.
BUOYANCY TUBE - PRESSURE
CORRECT PRESSURE
The correct pressure for the buoyancy tube is 240 mb/ 3.4 PSI.
The ambient temperature of the air or the Ambient temperature
Pressure inside the
buoyancy tube
water proportionally influences the
internal pressure of the buoyancy tube:
+ 1°C
+ 4 mb / + 0.06 PSI
- 1°C
- 4 mb / - 0.06 PSI
Thus it is important to anticipate:
Check and adjust the pressure of inflatable compartments (by inflating or deflating)
depending on the temperature (particularly when temperature variations are high
