PLUMBING
HOLDING TANK HEATER
–If Equipped
Your motorhome may be equipped with black
water and gray water holding tank heaters to
allow use of waste utilities in freezing
temperatures. The holding tank heater power
switch is located near the monitor panel. The
illuminated switch will glow when the power is
on.
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 AND 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.
WINTERIZING PROCEDURE
Your motorhome is equipped with a manually
operated waterline winterization system for your
convenience in winterizing fresh waterlines. This
action is necessary for storage in cold climates.
The winterization process blows out left over
water in the pipes, and adds antifreeze to prevent
pipes from freezing and bursting, possibly
causing extensive damage. Certain areas of your
water system require additional attention and
disconnecting or blowing out these lines may be
required. Be sure all water is drained from the
system.
We recommend performing Step 1 “Blow
Out Procedure” and Step 2 “Antifreeze Fill
Procedure” to properly protect the system.
