is dumped. The tanks should be emptied when they reach ½ full, or weekly,
to prevent stagnation and overfilling.
The motorhome is not designed for extended use in below freezing (32° F/0°
C) weather. With that said, the manufacturer is not stating that it cannot be
done, but merely stating the motorhome was not designed for use in extended
below freezing temperatures. There are precautionary measures that can be
taken for extended cold weather use.
Interior water lines, fixtures, and drains above the floor are normally protect-
ed from moderate freezing temperatures as long as the furnace is operating.
Cold temperatures can adversely affect water systems below the floor
level because the furnace heat does not provide heat to these components. An
optional Cold Weather Package is offered that provides limited protection to
the water system below the floor.
The SYSTEM HEAT switch has a dual purpose when the system heat
switch is in the ON position. First, it allows current to pass to a small "snap
disc." The snap disc is a thermostat that operates in the range of 40 to 56° F.
When the snap disc is in the CLOSED position, power is passed to both the
heat mat and the bay heater. The heating status can be monitored inside the
motorhome using the lighted switch. When temperatures lower to the operat-
ing range of the snap disc and the snap disc closes, the switch will illumi-
nate.
WARNING: The battery disconnect switches must be
turned off if the motorhome is left for an extended peri-
od of time (2hrs). The battery cut-off switch does not
control the bay heater and heat mats circuitry.
The dump valves and water pump by design will receive limited cold
temperature protection as long as the 12 Volt electric bay heater is operating.
Make sure the 12 Volt heater is turned ON and the thermostat on the bay
heater is set to a desired setting so that when the snap disc closes the bay
heater will operate.
NOTE: The bay heat system will quickly drain the
motorhome batteries when not connected to shore power
or operating from the generator. Only use the bay heat
functions when hooked to shore power or operating from the
generator. The Bay heater is not intended to heat the entire
bay.
Exposed drains and water lines may freeze quickly in below freezing
temperatures. If, by the way of prior experience, there are doubts as to what
temperatures the motorhome's water system will tolerate, and the water sys-
tem will not be used, winterize the water system using potable antifreeze.
When the tanks are dumped, additional potable antifreeze will need to be
added to the storage tanks.
