LOCATION
The compartment itself should be of vapor tight design
and completely independent of living quarters. A sheet
metal covered compartment may be readily sealed and
lends itself easily to treatment. The plant may have
to be removed for service, so make the door large
enough to facilitate removal of the unit.
The compartment location is determined by physical
size, access opening and most important, best mounting
support. Allow 2" clearance on all sides of the plant
for rocking on mounts.
POSITIONING
The following should be considered for accessibility
when mounting the unit in a compartment. (Position
so operating instructions and nameplate are visible
and/or install an accessible nameplate, data decal
or sticker.)
1. Make air discharge duct as short as possible.
Position so exhaust heated ait is not drawn into
cool air inlet.
2. Ait cleaner should be easy to remove and service.
3. Battery or batteries roust be accessible for service.
4. Oil fill tube cap should be easy to reach.
5. The control box switch should be visible.
6. Provide space for muffler.
7. Oil drain should be readily accessible.
8. Cylinder head readily accessible for service.
9. Rope start sheave should be accessible.
MOUNTING
The best method of mounting is to attach the plant
to a mounting platform using Onan vibration isolators.
See Figure 2. The vibration isolators must be properly
installed to minimize vibration. The Onan mounts
are a “fail-safe" type with mounting bolts that prevent
the unit from breaking loose if the mounts are damaged.
The mounting base should be fastened directly to the
supporting frame. Channel, box or angle iron can be
used for a mounting base frame. This will provide
the greatest support plus a base sealed against ait,
dirt and sound. Do not use sheet metal or thin plate
without a supporting frame. Plywood of sufficient
thickness for strength can be used, but unless it is
suitably sealed, it is vulnerable to climatic elements,
will tend to become oil soaked, and is not fireproof.
The supporting base or platform must be strong enough
to withstand the shock from sharp turns, bumps, holes,
etc. which accompany mobile applications. Brace the
mounting platform to eliminate any chance of the
platform bowing or bending.
It is desirable to mount the unit on a pullout tray to
facilitate service and repair. The load wires, control
wires and fuel lines must have enough slack and be
flexible so the unit can slide out without disconnecting
them. When using a pull-out tray, pipe the exhaust
gases into the air outlet. The air outlet duct may face
the botttxn, side or top of the enclosure, depending
on bow the unit is installed.
FUfil. SUPPLY (GASOLINE)
Install a separate fuel tank for the unit. If the plant
has to be connected to the vehicle supply tank, do
not tee off the vehicle supply line. The generating
unit must have a separate fuel line because the more
powerful vehicle fuel pump will starve the generating
unit for gasoline.
FUEL LINES
Use annealed copper or seamless steel tubing and
flared connections. Run fuel lines, at the top level
of the tank to a point as close to the engine as pos¬
sible, to reduce the danger of fuel siphoning out of
the tank if the line should break. Install lines so
they are accessible at all times and protected from
mechanical injury. Use nonferrous metal straps,
without sharp edges, to secure the fuel lines.
EXHAUST
If the unit is permanently mounted, pipe the exhaust
to a muffler mounted under the floor. If the unit is
mounted on a slide-out tray, vent the exhaust through
the air discharge duct. Flexible exhaust tubing (used
between the unit and the muffler) absorbs unit vibration.
If the exhaust line passes through a flamiSable floor
or partition, insulate with asbestos backed metal
collars where it passes through these barriers. Exhaust
lines may be asbestos wrapped to reduce heat radiation
within the compartment. However, care should be taken
to see that flexible exhaust sections that are wrapped
still retain their flexibility.
When installing mufflers, other than those supplied
with plant or if the exhaust system is excessively
complicated, the exhaust back pressure should be
checked. Exhaust back pressure at rated load, mea-
