KMACS 5 MANUAL
© 2003 KMDSI Document # 041112001
8. BLUE BREATHING AIR SUPPLY
PRESSURE GAUGE (M)
The Blue pressure gauge (M) indicates the pres-
sure remaining in the “BLUE” high pressure tank.
(NOTE: If two divers are supplied by the KMACS 5
both divers will be breathing from the same selected
high pressure supply).
9. ORANGE BREATHING AIR SUPPLY
PRESSURE GAUGE (L)
The Orange pressure gauge (L) indicates the pres-
sure remaining in the “ORANGE” high pressure
tank. (NOTE: If two divers are supplied by the
KMACS 5, both divers will be breathing from the
same selected high pressure supply).
10. YOKES FOR HIGH PRESSURE
CYLINDER ATTACHMENT (S)
The yoke fittings (S) provided have standard U.S.
scuba cylinder attachments as well as Din Fittings.
Each yoke has a bleeder valve to vent the remain-
der of the pressure in the whip when changing out
scuba bottles. The yokes attach to posts mounted
on the panel in the lid of the KMACS 5 for storage
and transport.
11. CASE (J)
The Dive Control panel (A) is attached to the bottom
half of the case (J). The top half of the case contains
the communicator panel with the yoke blocks and
the communicator if there are communications. If
there are no communications there are only the yoke
blocks. ( see picture in front of manual). The top is
not designed to be removed.
12. BREATHING AIR SUPPLY SELECTOR
VALVE HANDLE (I)
This handle (I) controls the two position Breathing
Air Supply Selector Valve and allows uninterrupted
diving operations while full air supply tanks replace
expended tanks. The selector valve controls ONLY
the high pressure air supply. It is NOT possible
to shut off any low pressure supply connected to
the low pressure inlet fitting (N), at the KMACS 5
itself.
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”.
When changing out the H.P. air supply cylinders,
always observe the diver’s umbilical pressure gauge
(B) for any sudden fall in pressure. Should this occur,
it indicates that the cylinder in use has mistakenly
been turned off. If so, immediately turn the cylinder
back on and move the selector valve handle to select
the full cylinder and change out bottles.
Due to the construction of the selector valve, it is
impossible for gas to back-flow from one cylinder
to the other.
