- OXYGEN SYSTEM
An oxygen system, supplying oxygen
I
II r ough five individual outlets, is
"val lable as q>tional equipment. The
YH lem is completely automaiic and
,-" quires no manual regulation for
I'IlIl nge of altitude or flow shut-off
.,.,he n the system is not in use.
The system consists of an oxygen
r V Ii nder, filler valve, pressu re
1T,\I~ e, pressure regulator, outlet
,·ollplings, and four disposable oxygen
lac e masks, complete with vinyl
pla stic hoses and flow indicators.
Th e face masks and hoses are stored
1 11 a plastic bag, normally stowed on
Ih e utility shelf when use is not an-
I id pated.
. The oxygen cylinder and shut-off
valve are located aft of the baggage
l ·o mpartment. Oxygen, under high
p ressure, flows from the cylinder
lu an automatic pressure regulator
which supplies filtered, low pressure
"xygen to five individual outlets. The
lIutlets, regulat.or, and a pressure
v,ag e that indicates oxygen cylinder
p ressure, are located in the overhead
.. l.J1sole panel. When the oxygen mask
lIu ses are plugged into the quick-
«lt sconnect outlet couplings, a con-
Ilnuous flow of oxygen is supplied to
Pilch face mask. A flow indicator
i ll each mask supply line shows if
IIxygen is flowing .
IMPORT _ \NT
Permit no smoking when using
oxygen. Oil, grease, soap, and
other fatty materials in contact
with oxygen constitute a serious
fire hazard. Be sure hands and
clothing are oil-free before han-
dling oxygen equipment.
OXYGEN SYSTEM
OPERATION
Prior to flight, check to see that
the oxygen cylinder shut-off valve,
located on the cylinder behind the
baggage compartment rear wall,
is full open (full counterclockwise).
Note the oxygen pressure gage read-
ing to be sure that there is an ad-
equate oxygen supply for the trip.
Refer to the Oxygen Duration Chart
(figure 8-4). See that the plastic bag
containing the face masks and hoses
is accessible, and that the masks
and hoses are in good condition.
To use the oxygen system, proceed
as follows:
(1) Select mask and hose from
plastic bag.
(2) If mask is not cormected to hose,
attach by inserting plastic tube on
mask into rubber hose connector on
delivery hose.
(3)
Attach mask to face.
(4) Select oxygen outlet coupling
in overhead console panel and plug
delivery hose into it. Oxygen will
flow continrusly at the proper rate-
of-flow for any altitude without any
manual
adjustments.
(5) Check the flow indicator in the
face mask hose. Oxygen is flowing
if the red indicator compresses
its return spring .
