e.
Assembly
To
assemble
the
control
panel
assembly, proceed as follows.
(1)
If removed, screw adapter (10, Figure 7-4,
Sheet 1 of 2) to the air panel mount (21,
Figure 7-4, Sheet 2 of 2) Using screws and
nuts attach the air panel mount (21) to the
panel. Screw cover (9, Figure 7-4, Sheet 1
of 2) on adapter (10).
(2)
Using screws (7) attach the pressure
regulator (8) to the control panel
(3)
Insert the service pressure gauge (6) into
the panel and attach using the gauge clamp
and nuts Insert scuba manifold pressure
gauge (1) into control panel and attach
using gauge clamp and nuts.
NOTE
Do not fully tighten hand valves or lever
valves
until
tube
assemblies
are
installed.
(4)
If washers (22, Figure 7-4, Sheet 2 of 2)
were removed from valves, place washers
(22) on valves (5, Figure 7-4, Sheet 1 of 2)
and insert valves (5) into the control panel
from the rear Attach to the panel using
valve holddown nut, attach valve handles to
valves and secure with handle nuts
(5)
Position the scuba manifold (26, Figure 7-4,
Sheet 2 of 2) with mounts (25) on the rear
of the control panel Using screws (3, Figure
7-4, Sheet 1 of 2) attach the manifold (26,
Figure 7-4, Sheet 2 of 2) to the panel
Position the supply manifold (18) with
mounts (25) and attach using screws (3,
Figure 7-4, Sheet 1 of 2) and washers (4)
(6)
Insert cam lever valve (2) into the panel
from the rear and attach to panel using the
cam lever valve (2) holddown nut. Using
nuts and clamps, install the gas cylinder
pressure gauges (1).
(7)
Position and connect scuba manifold to
charging valve tube assemblies (9) Connect
scuba
manifold
to
bleed
valve
tube
assembly (6)
(8)
Position and connect scuba manifold to
manifold pressure gauge tube assembly
(8), and service pressure gauge to pressure
regulator tube assembly (7)
(9)
Position and connect scuba manifold shut-
off valve to scuba manifold tube assembly
(6), and
pressure
regulator
to
scuba
manifold shut-off valve tube assembly (5).
(10) Position and connect supply manifold shut-
off valve to supply manifold tube assembly
(3), and recharge valve to supply manifold
tube assembly (3)
(11) Position and connect cam lever valve to
supply manifold tube assembly (2) and cam
lever
valve
to
pressure
gauge
tube
assembly (1).
When tightening valves on control panel
do not put tube assemblies in a binding
position.
(12) Tighten all cam lever valves (2, Figure 7-4,
Sheet 1 of 2) and hand valves (5)
6-7.
