APPLIANCES & SYSTEMS
Class A
•
If you are using the shoreline, the switch must
be in POWERCORD position.
•
If you are using the generator, the switch must
be in GENERATOR position.
The rear air conditioner will not operate if the
switch is not in the proper position for the power
source being used.
NOTE: The power cord must be plugged into the
generator receptacle for generator
operation.
GAS/ ELECTRIC WATER
HEATER
- Optional (with Motor Aid water
heating system)
The gas/electric water heater has a dual power
feature. It can operate from propane gas or 110-
volt house current; or it can use both at the same
time for quicker recovery at times when you are
using a lot of hot water.
Read the Gas Water Heater Operation
Manual for complete Safety Warnings,
Operating Instructions and Maintenance
Information before operating the water heater.
Be sure the water heater is filled with water
before starting either electric or propane
operation.
To fill the water heater, turn the
Water Pump switch on and open a hot water
faucet anywhere in the coach. When water begins
to flow steadily from the faucet, the water heater
is full.
Motor Aid
- Optional
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 to about 140
°
F
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.
For Electric Operation
Turn on the Water Heater electric element
switch. The shoreline must be connected or the
generator running for electric operation.
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.
