APPLIANCES & INTERIOR FEATURES
WATER HEATER BY-PASS VALVE
Your coach may be equipped with a water
heater by-pass valve for easier winterization of
water lines using RV antifreeze. The valve is lo-
cated inside the coach near the water heater. See
pg. 7-6 for the exact location in your coach.
Line up the arrow on the handle with the ap-
propriate arrow on the valve plate to either by-
pass or flow through the water heater.
Normal
Flow
CAUTION
Leave by-pass valve handle in NOR-
MAL FLOW position if draining
water and blowing out water lines.
Place in BYPASS position ONLY
when using antifreeze solution in
water lines.
MOTOR AID
The motor aid uses heat from the chassis en-
gine cooling system to heat water in the water
heater while driving. Hoses are routed from the
engine to a heat exchanger surrounding the water
heater tank.
Under normal conditions, the entire contents
of the water heater can be heated to a usable tem-
perature in a few hours of highway driving. This
means you can have hot water at the faucets im-
mediately 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.

CAUTION
Any leak in the heat exchanger or its
supply or return lines could cause loss
of coolant and subsequent engine fail-
ure. We recommend that you periodi-
cally inspect these connecting lines
and the heater to insure that no leaks
have developed.
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.
