WARNING
It is forbidden to attach the medium pressure power supply buoyancy
compensator hose to high-pressure output of the pressure regulator and the
use of any reductions on medium pressure hoses.
Prior to each dive, it is necessary to carry out inspection procedures to ensure all
components of the buoyancy compensator are functioning correctly. Even if you
dived during a given day using the buoyancy compensator, check the functioning of
all components before starting the dive. Failure to carry out the check by the user on
all or one of its points can lead to dangerous circumstances, consequently the loss
of health or life.
In order to prepare the buoyancy compensator for use, it is necessary to follow these
steps:
• visually check that none of the components of the compensator is damaged,
paying particular attention to the condition of belts, fasteners, inflator, the
outer shell compensator and medium pressure hose.
• check the connection to the harness of the buoyancy compensator,
• check the connection of the medium pressure hose to the inflator,
• check the correctness of tightness of the extraction-relief valves (the lower and
upper),
• check the function of orally filling the compensator inserting the inflator nozzle
in your mouth, and then pressing the deflator button while exhaling into
compensator bag. Fill the buoyancy compensator in this way with at least half
of its volume,
• check the function of orally filling the compensator by inserting the inflator
nozzle in your mouth, and then pressing the deflator button while exhaling into
compensator bag. Fill the buoyancy compensator in this way with at least half
of its volume,
• check the correctness of functions manually by opening the release-valve by
pulling the cord (strand). Pulling should cause air discharge which should
immediately stop after releasing the cord,
• fill the buoyancy compensator using the inflator button, then press the deflator
button and check if air comes out of the opening of the oral inflator. Repeat
this step several times,
• press the inflator button until the relief valve is actuated and paying attention
when releasing the deflator that the air flow immediately ceases.
• before diving, make sure that you have turned on the diving cylinder valve(s),
• ensure your buoyancy compensator is attached to the cylinder straps in a
secure way.
