5--2T--311a. Carefully make an 8 Inch incision in the evaporatorcable close to where you will attach the ground wireterminal.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 inchring terminal.e. Remove undercoating or paint from area whereground 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.Incision closed withelectrical tapeGroundInsulated ClampFigure 5-2 Grounded to ClampRemove undercoatingsecure to bare metalFigure 5-3 Grounded to Chassis Railh. Coat the terminal connection and hardware with anelectrical protectant.Route other ends of harnesses/cables to the electricalcontrol panel, which should be in a protected location.Cut excess harness/cable. Strip harness wires andattach terminal rings. Connect to the appropriateterminal strip number on the electrical control panel(refer to your enclosed system wiring diagram).5.4.2 Evaporator Chassis Ground, Gen 5Gen 5 evaporators are supplied with a 12 foot section ofgreen, 10 or 6 gauge wire, depending on the evaporatorassembly. One end of the green grounding wire will havea #10 ring terminal crimped to it. Securely attach thisend to the evaporator assembly top panel. The otherend of the wire will have a 1/4 inch ring terminaltie-wrapped to it. Cut the ground wire to desired length,strip off the insulation, and crimp the 1/4 inch ringterminal to the wire. The evaporator must then begrounded to the chassis rail as shown in Figure 5-2/Figure 5-3 or to the metal frame of the bus roof.5.5 CONTROLSOne of two control systems may be provided. A ManualControl Package or a Total Control Package.5.5.1 Manual controlsIf Manual Controls are provided, the controls may bemounted in a panel (Figure 5-4), without the panel(Figure 5-5), or as a dual system (Figure 5-6). Themanual controls must be located within easy reach ofthe driver. The Drivers Controls consists of anevaporator fan speed switch (three speed or variable)and an adjustable thermostat.NOTEThe Ambient Air Sensor (see Figure 5-4) mustbe located within the vehicle’s interior in order tosense the return air temperature.1.2.3.4.5.1.
