Inspection and Service

Inspect the unit on a daily basis (see "Daily Inspection" on
page 11).
Observe inspection intervals (see "Service Data" on page 14).

Oxygen Generation

The oxygen required for breathing is supplied by a solid chemical
substance called potassium dioxide (KO
with the carbon dioxide (CO ) and the water vapour (H
2
exhaled air. These two components of the exhaled air are absorbed
by the KO and release the chemically-bound oxygen (O
2
the process. The simplified reaction formulas are as follows:
3
O → 2 KOH +
2 KO + H / O
2 2 2
→ K
2 KOH + CO CO + H O + Heat
2 2 3 2
3
→ K
2 KO + CO CO + /
2 2 2 3 2
KO is both O source and CO
2 2
and exhaling causes the breathing air to flow from the breathing bag
through the KO cartridge to the heat exchanger and then back
2
again.
A volume-controlled valve governs the volume in the breathing bag.
