6. ORANGE AIR SUPPLY FLOW
INDICATOR LINES
The “ORANGE” air supply flow indicator line
indicates the flow path of breathing air from entry
into the KMACS 5 to exit to the diver’s umbilical(s)
at the fittings on the manifold (G). The second high
pressure whip is color coded ORANGE.
Starting from the high pressure air tank, the OR-
ANGE air supply flows through the whip into the
KMACS 5. Following the ORANGE flow indica-
tor line (K) it shows the flow to the ORANGE
Breathing Air Supply Pressure Gauge (L), then
to the Breathing Air Supply Selector Valve which
is controlled by the Breathing Air Selector Valve
Handle (H). The Selector Handle must be all the
way “DOWN” until it stops for the ORANGE
supply. The BLUE supply is off when the Selector
Handle is in the down position.
After flowing through the Selector Valve the OR-
ANGE air supply enters the Breathing Air Supply
Regulator (H) which reduces the high pressure
breathing air to an adjustable range between l15-225
psi (8-15.5 bars). Then the ORANGE air supply goes
to both diver’s umbilicals through the fittings on the
manifold (G).
7. LOW PRESSURE INLET FITTING (N)
The low pressure inlet fitting is positioned between
the connections for the two H.P. supply hoses. It
is marked by the arrow containing the words “L.P.
Supply”. Low pressure supply breathing air, usually
from a compressor (with volume tank) is supplied
through a whip (low pressure hose and fittings) that
attaches here. When the low pressure supply is the
only air source, the supply pressure will be indicated
on the umbilical pressure gauge (B). In the low pres-
sure supply mode, the selector/valve handle will he
positioned in the H.P. OFF ZONE.

CAUTION: When using H.P. air, the selector handle must be turned up until it stops for BLUE supply
or down until it stops for ORANGE supply. Never allow the selector handle to stay in the marked “H.P.
OFF ZONE”. Both high pressure air supplies are off in the yellow striped H.P. OFF ZONE”.
