AutoVents:
The auto vent is designed to assist in the smooth flow of water in the drain without creating a vac-
uum.
The auto vent, if stuck in the open position, can allow grey tank odors to enter the motorhome.
Some auto vents can double as "clean outs" in the event the line needs to be snaked out.
COLD WEATHER CONDITIONS
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 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 LP-Gas furnace heat does not provide heat to these components. A sup-
plemental 12 Volt bay heater and thermal snap disc are located in the water
service bay. The System Heat switch on the monitor panel operates the plumbing
service center bay heater to prevent waterlines from freezing and should be
turned on when ambient temperature approaches 44ºF (+/- 6ºF) and freezing
temperatures may occur.
System Heat Operation:
1. Turn the Systems Heat switch ON to supply
power to the snap disc thermostat.
2. When the bay temperature reaches 40ºF (+/-
6ºF), the snap disc thermostat will close. The
bay heater and the systems heat Active light will
turn on. The heater will continue to operate
until bay temperature reaches 55ºF (+/- 6ºF). The
bay heater and Active indicator light will turn
OFF.
NOTE:
The bay heater consumes about 20 Amps when
operating. House battery power can be quickly
consumed. It is recommended to hook to shore
power when using Systems Heat.
