Extreme Cold Weather Usage - Fleetwood EXPEDITION User Manual

Plumbing Systems and Holding Yanks
• Use a special holding tank deodorant chem-
ical approved for septic tank systems in the
black water holding tank. These chemicals
aid the breakdown of solid wastes and make
the system much more pleasant to use. Do
not put facial tissue, paper, ethylene glycol-
based or other automotive antifreeze, sani-
tary napkins or household toilet cleaners in
the holding tanks.
• Do not put anything solid in either tank
that could scratch or puncture the tank.
If the drain system does get clogged:
• Use a hand-operated probe to loosen stub-
born accumulations.
• Seriously clogged P-traps may require dis-
assembly. Be careful not to overtighten
when reassembling.
• Do not use harsh household drain cleaners.
• Do not use motorized drain augers.
• Sometimes the holding tank valve will get
clogged. In this case, a hand-operated auger
may be necessary. Be ready to close the
valve quickly once the clog is cleared. If the
seal gets damaged, it is easily replaced.

Extreme Cold Weather Usage
The holding tank area is heated through ducts
from the furnace. To assure adequate heat is
available to prevent holding tank freeze-up
during extreme cold weather use, the furnace
thermostat should be set no lower than 65
degrees if the outdoor temperature is 10 to 35
degrees. For temperatures lower than 10
degrees, set the thermostat 1 degree higher for
each degree the outdoor temperature drops
below 10 degrees. See the examples in the table
below.
