2. Open a faucet in the motor home to relieve
water pressure.

5. Close the faucet and turn on the water supply
before switching the water heater on.
Manually operate the pressure temperature re-
lief valve at least once a year.
MOTOR AID WATER HEATER
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 about 120°F
in about two hours or 100 miles of 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.
WATER HEATER BY-PASS VALVE
Your coach is equipped with a water heater
by-pass valve for easier winterization of water
lines using RV antifreeze. The valve is located on
the valve panel in the water center, or in the rear
compartment on the passenger side.
Open
Lift handle straight out to open P-T valve.
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.
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.
