3.11.2. Pressure Reducer with
alphaCLICK 2
(1) Place the compressed air breathing apparatus in a horizontal position with
the cylinder facing up.
(2) Hinge up tension clamp at cylinder strap (
Fig. 11) and thus loosen the
strap.
When exchanging compressed air cylinders of the same diameter
(without attached bumpers), only the tension clamp needs to be
opened.
(3) Close cylinder valve(s), release air from pneumatic system of the SCBA with
lung governed demand valve.
(4) For compressed air cylinders with
alphaCLICK 2
turn the handwheel on the
coupling side (arrow 1) in a clockwise direction first (
Fig. 16) and then,
when closed up to the stop, push downwards in the direction of the pressure
reducer (arrow 2).

Attention!
Do not remove the compressed air cylinder(s) from the cylinder strap or
transport the compressed air cylinder(s) by the handwheel.
This could accidentally open the cylinder valve.
(5) Lift compressed air cylinder(s) at the valve and pull out of cylinder strap.
