3.3.1.1. Preparing the Apparatus for Use with Two Compressed Air Cylinders
(1) Hinge up the cylinder separator to a vertical position in the middle of the
cylinder support until it catches.
(2) Connect T-piece to high pressure socket of pressure reducer.
3.3.1.2. Connecting Two Compressed Air Cylinders
(1) Place compressed air breathing apparatus horizontally so that the back face
is uppermost ( Fig. 17).
(2) Hinge cylinder separator (1) into a vertical position until it catches.
(3) If there is no T-piece connected to the pressure reducer, check gaskets on
the pressure reducer and T-piece and thread in T-piece loosely.
(4) Open cylinder buckle on the cylinder strap eliminating any tension by
extending the strap to full length pulling the small bar at the cylinder buckle
( Fig. 19).
(5) Push one compressed air cylinder through the cylinder retaining strap so
that the cylinder valve points to the T-piece and lies on one of the outer
supports.
(6) Loosely thread the cylinder valve onto the T-piece.
(7) Push a second compressed air cylinder through the cylinder retaining strap
so that the cylinder valve points to the T-piece and lies on the outer support.
(8) Loosely thread the second cylinder valve onto the T-piece.
With right-angled T-piece, align the compressed air cylinders by hinging
the pressure reducer and pulling the cylinders together (see Operating
Manual for T-pieces).
(9) Tighten all three high pressure connection handwheels.
