INSTALLATION CHECKS
INSTALLATION
Nearly all Onan electric generating sets are installed
by the motor home manufacturer. Although the
manufacturer must follow safety codes when install¬
ing, certain installation problems could arise after the
unit is installed and subjected to vibration. There are a
few areas that you as the operator should be concern¬
ed with. If in doubt about any aspect of your generator
set’s operation or safety, contact your nearest
authorized Onan Service Center. A daily inspection of
your installation should include the following:
EXHAUST
Check for leaks around manifolds, gaskets, and
welds. Make sure exhaust lines are not heating
surrounding areas excessively. If so, have corrected
immediately. Remember EXHAUST GASES CON¬
TAIN DEADLY CARBON MONOXIDE. Be sure all
holes to the inside of RV from set compartment are
sealed to prevent poisonous exhaust gases from
entering vehicles.
WARNING Ail exhaus * shielding supplied with unit
MUST be properly installed to prevent
overheating of compartment walls or the possibility of fire.
FUEL SYSTEM
With set running, check for leaks. Raw fuel will cause
fumes which could EXPLODE. Check around car¬
buretor and fuel pump inlets. Make sure fuel lines are
not rubbing against anything which could cause
breakage.
ELECTRICAL
AC Output: All AC leads (Ml, M2, M3 and M4)
terminate in generator sets junction box. These wires
should be connected to distribution box witi. mul¬
tistrand wire enclosed in a flexible conduit. Check all
wires (to and from the generator set) for fraying and
loose connections. For information on load connec¬
tions refer to operation section following.
Battery Connections: Battery positive (+) connection
connects to start solenoid. Battery negative connects
to location on rear of generator. Check terminals on
set and battery for clean and tight connections.
