10.
Do not lift or move the BC by pulling the inflator hose.
Such practice may result in irreparable damage to the BC.
11.
When diving in cold water (below 10 degrees Celsius), you
should take into account that the inflator may freeze, as a
result of which, it may supply air in an uncontrolled way,
or other irregularities in its operation may appear. Before
diving in cold water, it is necessary that you practice
emergency procedures should the inflator freeze!
Cold water diving (in the temperature lower than 10°C)
significantly increase the risk of inflator freeze, which
may result in uncontrolled air inflation or other irregular -
ities. In the case of inflator freeze you should follow the
procedures of your diving federation which you’ve leaned
on your diving course.
In order to minimize the risk of inflator freeze you must
follow these rules:
Diving in tight spaces, in the wrecks, under overhanging
reef walls and in the caves involves the risk of sudden
loss of buoyancy caused by the bladder’s puncture due
to the contact with sharp edges of wrecks or reefs or the
lock of the overpressure valve by the sediments falling
down from the ceiling. If the sudden loss of buoyancy
caused by compensator would happen, you should
immediately use the emergency source of buoyancy.
In order to minimize the risk related to sudden loss of
buoyancy we should:
1.
Use gas mixture according to the EN 12021 norm and
use only dry and clean cylinders filled in the authorized
stations. Increased humidity of the gas has a significant
impact on the increased risk of inflator freeze.
2.
Avoid adding large amount of air to the compensator at
one time since the high flow of air through the inflation
valve considerably increases the risk of valve freeze
while diving in cold waters. Instead you should control
the buoyancy by adding small amounts of air at one time.
3.
Perform the BCD maintenance as per the time periods
specified in this manual. Worn-out parts in the inflator or
any contaminants may trigger rapid growth of ice crystals
inside the inflation valve causing the valve freeze.
4.
While diving in waters of temperature lower than 10°C,
remain at the surface as short as possible.
1.
Always have the emergency source of buoyancy available
and make sure that you can use it at any time.
2.
keep proper distance from the wrecks and reefs. Sharp
edges may cause puncture or cut the compensator blad-
der resulting in sudden and irreparable loss of buoyancy.
3.
Avoid diving into places where sediments, rocks or other
solid particles may fall down from above, e.g. due to the
movement of fins or the flow of water. Falling particles
may block the overpressure valve in a closed or open
state, resulting in incorrect compensator operation.
