and J110-P.
(6). If radio equipment is installed, discon­
nect coaxial antenna cables.
(7). Disconnect wiring from power selector
switch and insulate wiring terminals.
Remove clamps that secure three-wire
bundles to panel structure.
(8). Check entire instrument panel/upper
support assembly for clamps or nylon
straps that restrict separation from
lower support structure. Disconnect any
such items.
(9). Remove hardware attaching upper
support (Z-brace) to panel structure.
(10). Remove hardware attaching base of
instrument panel/upper support
assembly to lower support structure
(Ref. Figure 203 or Figure 204).
NOTE:
Make notes of routing of all lines, cables
and wiring before removing panel assembly,
to aid in reinstallation.
(11). With assistance, carefully lift out
instrument panel/upper support
assembly.
B. Slim − Line Instrument Panel Installation
(Ref. Figure 203 or Figure 204) Before and
during placement of instrument panel/upper
support assembly into position on supporting
structure, check that all cables, wiring and
lines are routed properly.
NOTE:
If upper support does not align with
canopy structure, use special shim washers,
0.12 inch (3.048 mm) maximum thickness,
under both forward or both aft console-to-
support attachment points. Use one-half
shim thickness at both center attachment
screws and vary screw length accordingly.
(1). Mount instrument panel/upper support
assembly on lower support structure
and secure base in place with attaching
hardware.
(2). Attach Z-brace to upper structure.
(3). Route all lines and wiring into position
for connection. Ensure there is suffi­
cient slack for proper connection
without straining lines or wiring.
(4). Connect power supply wiring to power
selector switch and reinstall wiring
support clamps and straps.
(5). If radio equipment is installed, connect
coaxial antenna cables.
(6). Connect electrical plugs J9-P, J110-P
and J10-P as appropriate.
(7). Connect ventilating valve control cable
and perform an operational check (Ref.
Sec. 21-00-00).

and perform an operational check (Ref.
Sec. 28-00-00). Reattach pitot pressure
line clamp with hardware used to
attach cable under upper support.
(9). Connect thermocouple leads to terminal
board TB9 on TOT indicator. Check for
correct thermocouple circuit resistance.
(10). Connect engine torque gauge and
engine oil pressure gauge. Connect pitot
and static pressure lines to altimeter
and airspeed indicator.
(11). Check that all lines and wiring are
connected and secure; then reconnect
battery.
(12). Perform ground run-up of helicopter to
check operation of all indicating
systems (Ref. applicable PFM, Table
201, Sec. 01-00-00).
(13). Connect an external power supply and
perform a power-on check of all
systems. If there is a malfunction,
correct trouble as necessary.
(14). Bleed engine torque and engine oil
pressure lines as necessary (Ref. Sec.
79-00-00).
(15). Shut down helicopter and reinstall
instrument panel side fairings.
