Then place master switch to STOP position. Disconnect and remove the outboard drain line and reconnect the engine
fuel line to the fuel atomizer. Install engine combustor access panel (fig. 1-2).
2-2. Installation of Separately Packed Equipment
All equipment necessary for operation of the power unit is provided installed in or stowed in the compartments of the
2-3. Installation or Setting Up Instructions
Locate power unit as close as possible to the elements to be serviced by the power unit. Provide sufficient
clear area around the unit to permit opening of all doors and panels and unobstructed airflow to the air inlets and from the
exhaust openings. Provide adequate drainage of the power unit operating area.
Locations where power unit may be exposed to high humidity, sand, or dust, should be
avoided whenever possible. Moisture condenses on power unit parts and may cause
corrosion. Sand, dust, and dirt shorten life of power unit parts and can cause mechanical
Position the power unit on any reasonably level surface, then adjust position to obtain as near level as
Do not operate power unit if front to rear axis is more than 15 degrees from level with up to 10
degrees displacement to either side.
Perform inspection and service procedures as described in paragraph 2-1.
Ground connection. Connect one end of a number 6 wire to electrical system ground terminal (E2) (fig. 2-
3) and other end to a ground electrode, such as underground water piping system or ground rod. The ground electrode
shall be 3/4 inch minimum diameter if piping system is used. If ground rod is used, it shall be driven in earth to a depth
of 8 ft. minimum and shall have a 5/8 inch minimum diameter.
Fuel supply connection. Connect external fuel system filter assembly (fig. 1-16) to fuel inlet fitting as
shown in figure 2-4. Connect fuel hose assembly between fuel supply and filter assembly. Open fuel shutoff valve (fig.
2-4) and position fuel filter bypass valve to "BOTH" position. Check fuel lines and fuel filter assembly for evidence of
leakage. Correct all leakage before proceeding with installation connections.
Conditioned air outlet compartment divider panel installation. Install divider panel (fig. 1-16) and
compartment drain hoses (fig. 1-.16) in conditioned air outlet compartment (fig. 1-2) as follows.
Remove divider panel from battery access and storage compartment (fig. 1-2) and remove drain
hoses secured to bottom of panel.
Carefully install panel with cutout in panel corner around heated air line insulated collar in
compartment with left side of panel engaging angle slots in brace on left side of compartment (fig. 2-5). Engage slots in
rear edge of panel with hook in wall of compartment. Secure panel to compartment with the three wingstuds.
Use care during installation of panel to prevent damage to insulating foam around edge of
Install drain hoses (fig. 2-5) on fittings in bottom of divider panel ,and insulated collar around heated
air line. Position hose behind heated air lines as shown in figure 2-5.
External 24v dc auxiliary power source connections. If power unit batteries are discharged or otherwise
inoperative, connect an external 24v dc auxiliary power source to the power unit as follows.
If external 24v dc power source has a dc take off receptacle, connect external dc electrical power
input cable assembly (fig. 1-16) to take off receptacle and to external dc power source connector (fig. 2-3) on electrical
output connection panel.
If an external battery or batteries are used, install battery terminal lugs of external battery dc power
cable assembly (fig. 1-16) on battery terminals with polarity marks (+ and -) on terminal lugs matched to polarity marks
on -battery terminals. Connect dc power cable assembly to external dc power source connector (fig. 2-3) on electrical
output connection panel.
