Waterline & Tank Drain Valves - Winnebago 2010 Navion IQ Operator's Manual

SECTION 7 –
PLUMBING
DO NOT operate the holding tank heater
unless you are providing a supplemental 12-volt
power source to recharge the house batteries.
This means either the shoreline cord must be
plugged into a 120-volt source, or the auxiliary
generator must be operating, or the chassis
engine must be running (such as when driving
down the road). This will prevent excessive
discharge of the house battery.
NOTE: The holding tank heater pads are
electrical resistance type heating
elements. This type of heating element
typically uses a large amount of current
while operating. If the tank heaters are
used without a recharging source, they
will drain the house batteries in a
relatively short period. Typically the
batteries would not support overnight
heating without a supplemental charging
source.
WATERLINE & TANK DRAIN
VALVES
The water drain valves are used to drain water
from the water tank and the water supply lines
when preparing the motor home for storage or
when sanitizing the water system.
To open or close the drain valves, turn the
handles in the directions indicated by the
following illustration.
See the drain valve location chart at the end of
this section for locations on your model.
