APPLIANCES AND SYSTEMS
For Electric Operation
Press the Water Heater Electric switch to ON.
The shoreline must be connected or generator
running for electric operation.
For Quick Recovery Operation
(Dual Heating)
Turn ON both Water Heater switches -
propane gas and electric. This will help reheat the
Water Heater tank more quickly than a single
source would alone. Use this mode when you are
using a larger than normal volume of hot water.
Further Information
See the Water Heater manufacturer’s
operation manual provided in your InfoCase for
complete operating instructions, safety warnings,
and maintenance information.
MOTORAID WATER HEATER
–If Equipped
The motoraid 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 surrounding 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.
The motoraid also increases the capacity of
the engine cooling system.
PRESSURE-TEMPERATURE
RELIEF VALVE
On occasion, water may be seen seeping from
the water heater pressure temperature relief
valve. This is no cause for repair or replacement
of the valve.
Normally there is an air gap at the top of the
water heater tank, which acts as a pressure buffer.
In time, however, heated water may expand and
fill this air gap, causing a slight increase in water
pressure. This may cause the P-T valve to “weep”
until the air gap is manually replaced.

NOTICE
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.
