APPLIANCES & SYSTEMS
4 APPLIANCES & SYSTEMS
MOTOR AID WATER HEATER
The motor aid uses heat from the chassis
engine cooling system to heat water in the water
heater while driving. Hoses are routed from the
engine to a heat exchanger on the water heater
tank.
Under normal conditions, the entire contents
of the water heater can be heated in about two
hours or 100 miles of driving. This means you
can have hot water at the faucets immediately
upon arriving at a site, or even while driving if
needed.
The motor aid also increases the capacity of
the engine cooling system, allowing the engine to
run cooler under many conditions.
Motor Aid Water Heater and Rear
Auxiliary Heater Maintenance
Have your authorized dealer check all hose
clamp connections on the rear automotive heater
and the motor aid water heater at least every six
months and tighten them if necessary.
ELECTRIC ENTRANCE STEP
The power switch for the electric entrance step
is located to the left of the main entry door as you
enter the coach.
Automatic Mode - Step Switch ON
(Step Operates with Door)
With the Step switch in the ON position the
step is in Automatic Mode. This means it will
extend and retract automatically whenever the
screen door is opened or closed.
Stationary Extended Mode - Step
Switch OFF
(Step Remains Extended)
With the Step power switch in the OFF
position the step will extend when the screen
door is opened and will stay extended whether
the door is opened or closed.
CAUTION
Any leak in the heat exchanger or its
supply or return lines could cause loss of
coolant and subsequent engine failure.
We recommend that you periodically
inspect these connecting lines and the
heater to insure that no leaks have
developed.
WARNING
Do not use step unless fully extended.
Do Not Stand on step when vehicle’s
ignition switch is turned to either the “On”
or “Start” position. The step will
automatically retract, which may cause
personal injury. Always remember to
retract the step before moving the vehicle.
