Condensate Drain Lines
The three roof air conditioners are equipped
with condensate water pumps, which allows
water that is extracted from the roof air
conditioners to be pumped through three separate
drain lines (located at the rear of coach).
If you notice water running off of the roof
when the air conditioners are running, this is a
sign that one or more of the drain lines have
plugged and water is now flowing out of the
safety overflow of the air conditioner(s).
NOTE: It is normal for some water to run off the
roof when using your air conditioner in
“heat pump” mode.
See your Winnebago Industries
®
dealer for
service and proper cleaning of the drain lines.
HYDRONIC HEATING SYSTEM
The Hydronic Heating System in your RV
provides a continuous supply of hot water,
interior heat, and engine preheating. This system
features a 12-volt DC powered diesel burner
(which utilizes on-board diesel fuel) and a 120-
volt AC electric heating element, along with a
propylene glycol-based antifreeze and water
heating solution to give you the luxury of quiet,
continuous warmth in your motorhome.
NOTICE
Water running off the roof is a sign the
condensate drain lines are plugged and
require service. Failure to comply may
result in water damage to the roof.
