3.2.2.2. Connecting One Compressed Air Cylinder
(1) If necessary, thread the
alphaCLICK 2
cylinder adaptor with a specific torque
of 20-30 Nm into the cylinder valve.
(2) Place compressed air breathing apparatus horizontally so that the back face
is uppermost (
(3) Bring cylinder separator (1) into a horizontal position opposite the tension
clamp (4) until it catches.
When fitting the compressed air cylinder on the coupling of the pressure
reducer, it may tip down. In this case, support the pressure reducer with
your hand.
(4) Open tension clamp on the cylinder strap eliminating any tension by
extending the strap to full length pulling the small bar at the tension clamp
(
(5) Push compressed air cylinder through the cylinder strap (2) with the cylinder
valve toward the pressure reducer, so that it lies on the central support (3).
(6) Align the compressed air cylinder with the
alphaCLICK 2
axially to the
coupling and fit on the
alphaCLICK 2
coupling.
Attention!
Never push the coupling system together using excessive force.
(7) Close the coupling by pushing it together using a "small amount" of force
and checking that the arrow of the indicator ring is vertically aligned with the
back plate.
(8) Tighten cylinder strap gently by pulling the free end.
Attention!
Do not overtighten the cylinder strap! Damage can occur when using
excessive force to close the tension clamp and the SCBA might not be
ready for use.
The final fastening tension will be achieved when closing the tension
clamp.
(9) Check position of compressed air cylinder, re-position if necessary.
(10) Hinge tension clamp (4) gently and completely down over the centre until it
catches.
(11) If push force/tension is too high during hinging of the tension clamp, re-
adjust the strap length at the tension clamp. If the strap tension is too low,
re-adjust the strap length at the tension clamp (
(12) Fasten end of the cylinder retaining strap onto Velcro strip.
(13) Briefly open cylinder valve and check for escaping air, re-tighten if
necessary.
