Operation Warnings and Cautions
1. Do not simultaneously operate the generator
engine and a ventilator which could draw
exhaust gases into the vehicle.
2. Do not open windows or ventilators on the end
or side of the vehicle where exhaust pipe of
the generator is located.
3. Park the vehicle so that the wind will carry the
exhaust away from the vehicle. Also, note the
position of other vehicles to be sure their
exhaust will not enter your vehicle.
4. Do not operate the generator engine while
parked if vegetation, snow, buildings,
vehicles, or any other object can deflect the
exhaust under or into the vehicle.
Check auxiliary generator oil level frequently
during periods of use.
Check auxiliary generator oil level frequently
during periods of use. Refer to the generator
manufacturer’s information in your InfoCase for
specific recommendations.
ELECTRICAL SYSTEM –
HOUSE 12-VOLT DC
The DC voltage system consists of the chassis
battery, the 12-volt house batteries, and the 12-
volt power converter.
Converter
See “Power Center.”
Chassis Battery
The chassis battery is used to operate the
engine starter and automotive accessories and
controls found on the instrument panel. The
slideout room systems and the electric step are
also connected to the chassis battery.
See your chassis manual for further
information on chassis batteries and chassis
electrical system.
House Batteries
House batteries are “deep-cycle” type
batteries specially designed for recreational
vehicle use. They will provide longer lasting
power than standard automotive starting
batteries, and will withstand the frequent drain-
and-recharge cycles that occur under the
demanding conditions of a camping outing.
The house batteries supply power to 12-volt
equipment located in the living area of the motor
home. This includes the following 12-volt
powered components (if equipped): interior 12-
volt lighting, range exhaust fan, propane furnace
fan, fresh water pump, systems monitor panel
with water level and holding tank gauges,
refrigerator, roof vent fans and 120-volt electrical
generator starter.
The house batteries can also provide
emergency power to start the engine if the chassis
battery is discharged. (See “Battery Boost
Switch” or “Aux Start Switch.”)
House batteries are automatically charged by
the chassis alternator while the engine is running.
WARNING
The exhaust of all internal combustion
engines contains carbon monoxide (CO).
This poisonous gas is colorless, odorless,
tasteless, and lighter than air. The
exhaust systems of both your motor home
engine and your generator engine have
been installed with your safety in mind.
However, certain precautions must be
taken when using them to protect yourself
from conditions beyond the control of the
manufacturer.
WARNING
Never check generator oil level while
generator engine is running.
