Filling cylinder
3.2.
WARNING
Filling pressure must not exceed the rated working pressure of cylinder.
(1)
Check period of validity for the cylinder.
(2)
Check for appearance damage.
(3)
Check if the threads connections are dry, the seal ring is not damaged and the inside of the cylinder is dry.
(4)
Check the cylinder valve for damage and function.
(5)
Connect the cylinder valve and the fill device air tight.
Heat emission of composite cylinder will spend a longer time than traditional metal cylinder during the
period of air fill because the material of composite cylinder is the thermal insulated material. The
temperature of cylinder maybe exceed 30
°C
when the filling pressure reaches the working pressure, but
when the cylinder temperature drop down to the same with the environment temperature, pressure in
the cylinder will drop as well, and the cylinder is not filled enough as specified. So, air filling can be
continued until it is fully filled.
Empty cylinder
3.3.
WARNING
Do not direct valve outlet of G5/8 to any person to avoid any injuries.
(1)
Open the cylinder valve slowly to empty the cylinder, and close the cylinder valve when the air flow is low (to
avoid the creation of humidity/ice inside the cylinder).
Fix the cylinder stably during the period of air emptying to prevent cylinder from rotation.
Connecting cylinder
3.4.
(1)
Place compressed air breathing apparatus horizontally so that the back face is on top.
(2)
Check gasket on pressure reducer for proper condition.
(3)
Open cylinder buckle on the cylinder strap eliminating any tension and extend the strap.
(4)
Push compressed air cylinder through the cylinder strap with the cylinder valve toward the pressure reducer, so
that it lies on the central support.
(5)
Thread cylinder valve onto pressure reducer, if necessary, bring the compressed air breathing apparatus with
valve up into a vertical position.
(6)
Tighten cylinder strap by pulling the free end.
(7)
Check position of compressed air cylinder, retighten if necessary.
(8)
Push cylinder buckle down until it catches.
(9)
Fasten end of the cylinder retaining strap onto Velcro strip.
(10)
Briefly open cylinder valve and check for escaping air, retighten if necessary.
