PLUMBING
Holding Tank Heater Switch
(Located near monitor panel)
-Typical View
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, 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 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
