Winter Traveling; Heated Tanks - Airstream Interstate 24X Owner's Manual

Winter Traveling

Traveling in sub-freezing temperatures will require
certain precautions to protect the plumbing system
and your personal belongings from being damaged by
freezing�
While traveling, simply use your common sense�
How cold is it? How long will it be before you can turn
the heat on? Is the temperature dropping or rising?
Remember, when driving at 50 MPH, the wind chill
factor will cause the interior of the touring coach to cool
much faster than a touring coach that is parked�
1� You should have a plentiful supply of fuel as the
heat from the furnace warms the touring coach and
keeps the fresh water lines and black water holding
tank from freezing�
2� If your stay is longer than overnight, you should
try to have 120-volt electricity available� Of course,
you can run your generator to recharge the
batteries, or even use the generator continually,
keeping an eye on your generators fuel� Since
the generator starts off the house batteries, it
is recommended to start the generator prior to
running the batteries down�
3� Minimize the use of electricity if a 120-volt power
source is not available�
4� Leave cabinet doors and the wet bath door slightly
open at night to allow circulation of air in and
around all components�
5� Save 12-volt power by using non-toxic RV-
approved antifreeze in the gray water holding tank
instead of the heating pads to prevent freezing�
Quantity of antifreeze needed will vary with
ambient temperature and the amount of liquids in
tank�
6� For extended stays in cold weather, insulate all
water lines outside the touring coach� You should
remember that low temperatures in combination
with high winds cause an equivalent chill
temperature much below what your thermometer is
reading� For instance, with an outside temperature
of zero degrees, and the wind velocity of 10 miles
per hour, the equivalent chill temperature is -20°F�
7� Remember to remove and drain the exterior
shower faucet to prevent freeze damage�

General Information

Heated Tanks

12-volt heat pads are installed with the fresh and gray
water tanks to help prevent freezing� The tank pads
are controlled by the switch located in the overhead
compartment, behind the driver's seat� When the
outside temperature is near freezing, simply switch
"ON" the holding tank heaters� Built-in sensors will
activate the heat pads when the contents of the tanks
drop to 44°F� Once the liquid is heated and rises to
64°F the heat pads will automatically deactivate�
Switch the power "OFF" when the ambient outside
temperature remains above freezing or if the tanks are
empty� The tank heaters will quickly deplete the house
batteries unless the unit is plugged into an external
AC power source or the generator is ran to operate
the inverter/charger� To conserve battery power, RV
antifreeze may be used to protect the gray and black
tanks�
NOTE
The black tank is installed above the floor where
heat from the furnace will keep it from freezing.
NOTE
Drain and winterize if the water systems are not
being used during winter traveling. Refer to Section
9 - Maintenance in this manual for winterizing
instructions.
