Cold Weather Use
The motorhome is not designed for extended use in below freezing (32°F/0°C) weather. There are
precautionary measures that can be taken for extended cold weather use.
Interior water lines, fixtures, and drains above the floor are normally protected from moderate freezing
temperatures as long as the furnace is operating.
Cold temperature can adversely affect water systems below the floor level because the furnace heat does not
provide heat to these components.
A bay heater with a “Snap Disc” thermostat is used to heat the water control bay.
System Operation:
1. Systems heat switch is turned ON to apply power to the snap disc thermostat and bay heater.
2. When the bay temperature reaches 40º F +/-6º F the snap disc thermostat closes, applying power to the
bay heater. The systems heat active indicator light will be lit. The twelve-volt heater continues to operate
until the bay temperature reaches 55º F +/-6º F. The indicator light will then turn OFF.
Exposed drains and water lines may freeze quickly in below freezing
temperatures. If, by the way of prior experience, there is doubt as to what
temperature the motorhome water system tolerates and the water system
will not be used, winterize the water system using potable antifreeze. When
the tanks are dumped, additional potable antifreeze needs to be added to the
storage tanks.
WARNING:
The battery disconnect switches must be turned off if the
motorhome is left for an extended period of time (2 hrs). The
battery cut-off switch does not control the bay heater circuitry.
NOTE:
The heat system quickly drains the motorhome batteries when not
connected to shore power or operating from the generator. Only
use the heat functions when hooked to shore power or operating
from the generator
