Range; Refrigerator; Operation - Airstream International 2017 Owner's Manual

Range

There is little difference between the operation of home
gas ranges and the trailer's range� If, however, you are
used to an electric range, operating confidence can be
quickly gained by reading the manufacturer's directions
provided in the owner's packet� Manufacturer's service
and parts manuals are also available�
An operation manual for the range has been
provided with your owner's packet. If this has not
been provided with your trailer, contact the listed
manufacturer to obtain. Their manual contains
specialized warnings and cautions that should be
reviewed prior to operating the appliance.

Refrigerator

Review all refrigerator literature supplied in your
owner's packet or stored in the refrigerator prior to
operating it�
In an absorption refrigerant system, ammonia is
liquefied in the finned condenser coil at the top-rear of
the refrigerator. The liquid ammonia then flows into the
evaporator (inside the freezer section) and is exposed
to a circulating flow of hydrogen gas, which causes the
ammonia to evaporate, creating a cold condition in the
freezer�
The tubing in the evaporator section is specifically
sloped to provide a continuous movement of liquid
ammonia, flowing downward by gravity, through this
section� If the refrigerator is operated out-of-level
when the vehicle is not moving, liquid ammonia will
accumulate in portions of the evaporator tubing� This
will slow the circulation of hydrogen and ammonia gas,
or in severe cases, completely block it, resulting in a
loss of cooling�

WARNING
Any time the trailer is parked for several hours with
the refrigerator operating, the trailer should be leveled
to prevent the loss of cooling� The trailer needs to be
leveled only so it is comfortable to live in (no noticeable
sloping of floor or walls).
When the trailer is moving, the leveling is not critical,
as the rolling and pitching movement of the trailer will
pass to either side of level, keeping the liquid ammonia
from accumulating in the evaporator tubing�

Operation

The refrigerator requires 12-volt current to operate,
even if running on LP or 120-volt modes� The 12-volt
is used to power the circuit board that directs the
refrigerator functions� When running in a mode such
as LP, it means the heat source, by far the largest
power requirement to evaporate the ammonia, is being
provided by an LPG burner�
The fan switch, shown below, is mounted on the left
panel as you enter the trailer on the 19 ft� model� On
all other models, refrigerators vent through the roof
and do not require a fan� The fan is thermostatically
controlled when the switch is on�
The fan increases the cooling efficiency of the
refrigerator; therefore Airstream recommends leaving
the switch on whenever possible� Please note that
turning the fan off during hot, humid weather conditions
may substantially affect the cooling capacity of the
refrigerator�
