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� Consider how cold it will get, how long
it will be before you turn the heat back on, and if the
temperature is falling or rising� Remember, when
traveling, the wind chill factor will cause the interior of
the touring coach to cool much faster than when it 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 and black water holding
tanks 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�
Heated Tanks
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 touch screen
Multiplex control panel� 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� Turn the power OFF when the
outside temperature remains above freezing or if the
tanks are empty� The tank heaters will quickly deplete
the house battery unless the unit is plugged into an
external AC power source or the generator is used
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 help keep it from
freezing.
NOTE
Drain and winterize the water system when not
being used during winter travel; see Winterizing
and Storage on page 9-10 .
