Winter Traveling; Heated Tanks - Airstream INTERSTATE 24 TommyBahama 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 back 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 must have at least 1/4 tank of fuel to run the
hydronic heating/hot water system as the heat from
the furnace warms the touring coach and keeps the
fresh water lines and black water holding tank from
freezing� If your fuel tank drops below 1/4 tank, the
hydronic system will automatically shut off� This 1/4
tank reserve is so you can travel to refuel�
2� If your stay is longer than overnight, you should
endeavor to have a shoreline hookup�
3� Minimize use of electricity if 120-volt power source
is not available�
4� Leave cabinet doors, wet bath doors, and
wardrobe doors slightly open at night to allow
circulation of air in and around all components�
5� Save power by using non-toxic RV- approved
antifreeze in the gray water holding tank instead
of the heating pad 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

Screen images may vary slightly with continuous
improvements/firmware updates
The touring coach has 12-volt heat pads installed with
the fresh and gray water tanks to help prevent freezing�
The tank pads are controlled by the Multiplex control
panels� When the outside temperature is near freezing,
simply switch "ON" the 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 eventually deplete
the house battery unless the unit is plugged into an
external power source� 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 all models if the water systems
are not being used during winter traveling;
