GENERAL INFORMATION
CYLINDERS – CO2 OR SCUBA BOTTLES
Control Code and Tare Weight (TW) are stamped on the upper shoulder of the bottle. The cylinder
is subject to a hydrostatic test every 5 years, and must be decommissioned if it fails the test.
The CO
2
bottles have a safety or overpressure disk on the operation head. In the event of
overpressure due to unusual ambient climatic conditions, this disk ruptures to discharge the
cylinder, thus preventing any damage to it.
All CO
2
bottles, compressed air bottles and dive cylinders should be laid down on the ground
when not in use. A compressed air cylinder when left standing up can become a life threatening
hazard. If it were to fall and shear its neck, it will become a life threatening projectile.
HOW TO CHECK A CO2 GAS CYLINDER
The Tare Weight is stamped on the bottle. Add 11 pounds of CO
2
charge to this figure, to
determine gross weight of bottle and gas.
A precision scale is needed to check actual weight. Weigh the cylinder with its operation head and
compare with the previously determined weight.
The acceptable tolerance is + or - 5 % of the gross weight.
INFLATION HIGH PRESSURE HOSES
Check for any cracks or cuts. If detected, change the hose (Never repair a high-pressure hose).
Change all fiber gaskets after each CO
2
inflation, or use “re-usable” O-rings.
Neoprene o-rings do not have to be discarded and replaced after each use, but MUST be checked
for cracks and changed accordingly.
CO
2
, when discharged into the atmosphere, goes from its liquid stage to a gaseous one. During
this time called its sublimation, the gases will reach -70 to -80 degrees C, or -94 to -112 degrees
F.
Adequate precautions must be taken not to exhaust CO2 these gases into sensitive environments.
Adequate eye and hand protection gear must be worn at all times.
DANGER: Do not inhale CO2 gases. Use an adequate respirator and only use CO2 gases in well-
ventilated areas.
WARNING
NEVER REPAIR AN INFLATION HOSE always REPLACE IT.
NEVER RE-USE A CRUSHED GASKET always REPLACE IT.
SERVICE YOUR CYLINDERS REGULARLY IN ACCORDANCE WITH
FEDERAL, NATIONAL, STATE, AND LOCAL REGULATIONS.
MAINTENANCE - EVERY 6 MONTHS:
Service all valves, valve inserts, valve caps and l/C valves by cleaning their threads, washers and
O-rings, and calibrate them where applicable. Service all I/C valves every 6 months or as required.
Pressure test: inflate boat to 240 mbar, check with shop gauge & tighten all valves & caps.
Check the air tightness of all inflation points & valves with a soap & water solution for bubbles
Change all O-rings every 12 months, as that is their life expectancy.
Inflate boat; stabilize its pressure for 1 hour. Record the ambient temperature at the end of it.
Top up pressure to 240 mbar if needed. Always start pressure tests @ 240/250 millibars.
Isolate all compartments, valves in navigation position “green area” and clamp the lower buoyancy
tube to isolate them. After 5 hours, open all chambers between themselves and take the pressure
reading: Correct any variations in pressure in proportion to the ambient temperature variation. Add
or subtract to the new-recorded pressure 4 millibars for every 1 degree Celsius (1.8º F = 1ºC)
increase or decrease shown on the pressure gauge. Only deal with pressure drops greater than 4
mbar per hour (i.e. 20 mbar for 5 hours). If temperature goes up, reduce as many times 4 as
Celsius difference.
