a. Carefully make an 8 Inch incision in the evaporator
cable close to where you will attach the ground wire
terminal.
b. Locate the green #10 wire from within the harness/
cable.
c. Cut the green #10 wire and pull from the cable.
d. Strip insulation from wire end and install a 1/4 inch
ring terminal.
e. Remove undercoating or paint from area where
ground will be attached.
f. Securely attach the ground wire terminal with self tap-
ping hardware or bolt (See Figure 5-2 & Figure 5-3).
g. Close incision in the cable with electrical tape.

h. Coat the terminal connection and hardware with an
electrical protectant.
Route other ends of harnesses/cables to the electrical
control panel, which should be in a protected location.
Cut excess harness/cable. Strip harness wires and
attach terminal rings. Connect to the appropriate
terminal strip number on the electrical control panel
(refer to your enclosed system wiring diagram).

5.4.2 Evaporator Chassis Ground, Gen 5

Gen 5 evaporators are supplied with a 12 foot section of
green, 10 or 6 gauge wire, depending on the evaporator
assembly. One end of the green grounding wire will have
a #10 ring terminal crimped to it. Securely attach this
end to the evaporator assembly top panel. The other
end of the wire will have a 1/4 inch ring terminal
tie-wrapped to it. Cut the ground wire to desired length,
strip off the insulation, and crimp the 1/4 inch ring
terminal to the wire. The evaporator must then be
grounded to the chassis rail as shown in Figure 5-2/
Figure 5-3 or to the metal frame of the bus roof.

5.5 CONTROLS

One of two control systems may be provided. A Manual
Control Package or a Total Control Package.

5.5.1 Manual controls

If Manual Controls are provided, the controls may be
mounted in a panel (Figure 5-4), without the panel
(Figure 5-5), or as a dual system (Figure 5-6). The
manual controls must be located within easy reach of
the driver. The Drivers Controls consists of an
Ground
evaporator fan speed switch (three speed or variable)
and an adjustable thermostat.
The Ambient Air Sensor (see Figure 5-4) must
be located within the vehicle's interior in order to
sense the return air temperature.
