WARNING:
Carbon Monoxide hazard!
To prevent generator
exhaust gasses from
entering the motorhome
when parked, position the
dash air conditioner to
the recirculation position
by turning the ignition
on, activating the blower
fan control and set the
dash HVAC system to
Recirculation mode. The
blower and ignition key can
now be turned off. This will
close off the dash HVAC
system to the outside.
Engine exhaust contains
Carbon Monoxide, which
is poisonous and can cause
unconsciousness and/or
death. Inspect the exhaust
system before starting the
generator. Do not block
the exhaust pipe or put
the motorhome where the
exhaust may accumulate
outside, underneath, or
inside the motorhome or
nearby vehicles. Operate
the generator only when
there is a safe dispersion of
exhaust. Monitor outside
conditions to ensure the
exhaust continues to
disperse safely.
