Lids of the regeneration cooler and CO
2
absorber
The lids of the regeneration cooler and CO
2
absorber have an
identical design, but cannot be used interchangeably.
– Release the fasteners to open (see Figure A). Push the
catches on the fasteners evenly onto the tabs on the lower
part to lever the lid off the lower part.
– When closing, pay attention to the recess in the lid and the
tab on the lower part (see Figure B). This prevents any
mix-ups between the lids on the breathing air cooler and
the CO
2
absorber. Push the lid onto the lower part when
closing. Hook the catches on the fasteners under the tabs
(see Figure B-1). Push the fasteners closed (see Figure B-
2).
Connecting piece
The direction of flow is marked with an arrow on the
connecting piece. The direction valves and connecting piece
are designed to prevent confusion during assembly so that
the flow is ensured.

The carrying frame has various holders into which the
following components are hooked:
– CO
2
absorber (1)
– Breathing air cooler (2)
