NOTE: The holding tank heater pads are
electrical resistant-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 waterline and tank drain valves are used
to drain water from the water tank and the water
supply lines when preparing the motorhome for
storage or when sanitizing the water system.
See the “Water System Drain Valve
Locations” chart at the end of this section for
locations on your model.
