excessive force to the knobs; air pressure from the
tanks will create a good seal. Be sure the bleed valve
on each yoke is in the closed position. Do not turn
the cylinders on at this time.
Prior to connecting the low pressure hose to the
KMACS 5, the deck whip should be flushed with air
to make sure no foreign matter is in the hose. Con-
nect the deck whip to the low pressure compressor
and while firmly holding the end of the hose start
the compressor and flow air through the deck whip
for at least one minute. Attach the low pressure hose
to the low pressure inlet fitting (N) and screw the
fitting down finger tight. While using one wrench
to hold the low pressure inlet fitting tighten the hose
fitting with a second wrench. Do not use excessive
force as this will only damage the fitting and cause
it to leak.
2.4 CONNECTING DIVER’S HOSES
TO THE KMACS 5
Each diver’s umbilical should be color coded with
plastic tape to identify each individual hose. This
action will not only serve to make it easier to connect
the hoses, but will also serve to differentiate between
hoses for purposes of inspection or repair.
A standby diver should always be equipped and
ready to go to the diver’s aid whenever a surface
supplied diver is working in the water. Generally,
it is not necessary for more than one diver to be in
the water at a given time when using surface sup-
plied gear. However, a standby diver is considered
essential for safe, surface supplied operations. The
standby diver can be either a scuba diver or another
hose supplied diver since the KMACS 5 provides
enough air for two hose supplied divers. In contami-
nated water diving operations, however, both divers
must be equally equipped with a vulcanized rubber
dry suit, dry gloves, and Kirby Morgan dive helmet
equipped with either a double exhaust system or the
new TriValve™ exhaust system.
CAUTION: Contaminated water diving
operations are very hazardous. They should
not be attempted without specialized
training, procedures, and equipment.
Remove the protective caps from the outlets of the
manifold (G) on the console. Connect the diver’s
umbilical hose fittings (air supply hose and pneumo)
to the KMACS 5. Remove the end caps from the
hoses themselves and while firmly holding the end
of the hose, blow out the lines before connecting the
Check the function of the selector handle to ensure
correct operation.
If available, a low pressure compressor should be
used as the primary air supply and scuba cylinders
should be used as a backup, or reserve air source.
CAUTION: Low pressure compressors used
for breathing air should be specifically
designed for diving. Paint compressors
or similar equipment are unacceptable for
diving applications. (Contact KMDSI for a
list of equipment manufacturers who supply
compressors with breathing quality air).
DANGER: If a low pressure compressor
is used, the intake must be at a sufficient
distance from and upwind of the exhaust.
If exhaust gas is sucked into the intake,
the diver will suffer from carbon monoxide
poisoning. This can be fatal.
