110-VOLT ELECTRICAL SYSTEM
City Power
The Airstream converter system enables you to use
the lights and appliances whether operating on self-
contained battery power or hooked up to 110-volt city
power. The 12-volt light bulbs give off the same light
as regular household bulbs, so that when operating
on self-contained battery power, everything works
normally except the 110-volt convenience outlets and
110-volt appliances.
Exterior outlets for 110 volts are located on the curbside
exterior wall.
NOTICE: When operating with city power make very
certain that the service is 110 volt and not 220 volt.
The converter system is designed to maintain constant
output voltages regardless of the variances that occur in
city power systems. The transformer design eliminates
the need for complex electronic sensing systems to
charge the battery, minimizing the possibility of failures
and greatly increasing its overall reliability.
NOTICE : Your Airstream has a gas electric water
heater. Make sure the 110-volt water heater switch
in the bathroom is turned off when you plug your
trailer in to city power. If your plumbing and water
heater are full of water the switch may be left in the
on position.
WARNING : When the three-pronged plug
can be used there will be no problems with proper
polarity or grounding.
In some older parks and other locations where three
pronged outlets are not available, certain precautions
to insure proper grounding and polarity must be taken.
These precautions are listed below:
1. Attach the three-pronged plug to a two-pronged
adapter. The third conductor line of this adapter has
a short wire lead, which must be grounded.
2. For proper grounding connect the short ground
lead to a grounded outlet box or to a cold water
pipe. When no water pipe is available drive a
metal rod two feet into the ground and attach the
ground lug to it, thus providing the unit with proper
grounding. To operate self-contained, simply
disconnect the power supply cable.
When your trailer is hooked up to 110 volt AC the
converter system automatically charges the trailer
batteries and, if the 7-way connector is hooked up, your
tow vehicle battery as well. The speed and degree of
charge depends on how much power is used for lights
and appliances, as only the surplus goes to charging
the battery. If you are making an extended stay, then
you should, if it is available, keep your trailer hooked
up to a 110 volt current.
On rear bed models circuit breakers for the 110-volt
system are located in the roadside rear corner of the
trailer in the overhead cabinet.
On front bed models 110-volt breakers are located
inside the converter mounted on the pantry cabinet.
they are accesses by opening the brown converter
door.
While you are connected to the 110-volt receptacle
the wiring is protected by circuit breakers in the
breaker panel. In the event of a failure of a 110-volt
circuit check your circuit breakers first. If a breaker
continues to trip after you have reset it several times,
your circuit may be overloaded with appliances or there
may be a short in the circuit, The 110-volt switch on the
water heater, with its 12 amp draw, would be one of the
easiest places to reduce the load on 110-volt circuits. If
lessening the load does not solve the problem consult
an Airstream Service Center.
The 110-volt electrical system provides power to
operate the air conditioner, converter and 110-volt
receptacles for portable appliances. The power is
carried through the 110-volt city power flexible cord to
the 110-volt distribution panel, and then is distributed
to each appliance or receptacle.
All wire, components, and wiring methods conform to
federal and state requirements.
