Monitor Panel; Inverter/Charger; Converter - Airstream Interstate 2019 Owner's Manual

Interior

Monitor Panel

The "Home" screen of the Multiplex Systems main
control panel displays the fluid levels of the Black
Water, Grey Water, Fresh Water, and the LP gas tanks�
The panel also shows the voltage status of the main
(chassis) and the auxiliary (house) batteries�
The fluid monitoring system has been calibrated at the
factory for the size tanks the touring coach uses and,
therefore, should never need another calibration�

Inverter/Charger

The Inverter/Charger is a DC to AC inverter and a 50-
amp multi-stage battery charger� The remote control
module is mounted in the front locker behind the
drivers seat�
The Inverter/Charger charges the batteries and
converts 12-VDC to 120-VAC current for distribution
to the entertainment devices� To operate your
entertainment circuit the inverter must be ON, unless
connected to generator or shoreline power�
If power is not needed to the entertainment circuit
make sure the inverter is turned OFF to conserve
battery power� The inverter will have a slight power
draw even when turned off but the power consumption
will be even greater if left on�
5-14
NOTE
Airstream calibrates all settings at the factory and
recommends adjustments not be made.
An extensive owner's manual for the Inverter/
Charger is provided in the Airstream Owner's
Packet. Make sure to read, understand, and follow
all information, notes, Cautions, and Warnings in
the manual before operating the Inverter/Charger.

Converter

The Airstream converter system enables you to use the
12-volt lights and equipment whether operating on self-
contained battery power or hooked up to 120-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 120-volt convenience outlets and
120-volt appliances�
CAUTION
When operating with city power, make very certain
that the service is 120 volt, not 240 volt.
The converter system is a transformer designed to
maintain constant output voltages regardless of the
variances that occur in city power systems� The design
eliminates the need for complex electronic sensing
systems to charge the batteries, minimizing the
possibility of failures and greatly increasing its overall
reliability�
In some older parks and other locations where three-
pronged outlets are not available, certain precautions
to ensure 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 that 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�
NOTE
When the three-pronged plug can be used,
there will be no problems with proper polarity or
grounding with a properly-wired shoreline outlet.
