outlets.Follow directions on the

amount to use for your motorhome.
WA RNING
NEVER use automotive antifreeze/
coolant in your RV water system.
Automotive coolant/antifreeze contains
ethylene glycol which, if ingested, can
cause blindness and can be fatal.
The Water Control Panel features a
Winterization (diverter) valve with an antifreeze
siphon tube to draw non-toxic RV water system
antifreeze into the waterlines.
17. Double check that the water control panel is
set to the "winterize" configuration as
indicated on the water control panel.
18. Attach antifreeze siphon tube on the Water
Center Panel.
• Antifreeze Siphon Tube
attached to the tank fill inlet

19. Insert the end of the siphon tube into a pail or
other container with 2 to 3 gallons of non-
toxic RV antifreeze solution.
NOTE: Ensure that all drain valves are
CLOSED before pumping RV antifreeze
into the water system.
Refer to the "Water System Drain Valve
7-16
Locations" chart at the end of this
section for valve locations on your
model.

20. Turn the Water Pump switch ON.
21. Open each hot and cold water faucet handle/
knob in the motorhome - one at a time each in
turn until antifreeze solution just begins to
flow from the faucet, then close.
22. With the exterior shower/wash station hose
connected, point hose toward the ground and
squeeze handle until antifreeze solution
begins to flow, then disconnect hose. Do this
for both wash stations.
23. Press the toilet flush pedal and hold until
antifreeze begins flowing into the toilet.
Leave small amount of antifreeze that remains
in the bowl.
24. Disconnect Antifreeze siphon tube.
When Done Adding RV Antifreeze
25. Turn Water Pump switch OFF.
26. Leave the Water Control Panel in the
"Winterize" configuration until you are ready
to bring the motorhome out of storage.
27. Replace the protective cap onto the end of the
Antifreeze Siphon Tube to keep out insects
and debris when not in use.
Fill Drainage System P-Traps
28. Pour about one cup of RV antifreeze down
each drain for the galley sink and lavatory
sink. This fills the drain trap pipes to prevent
holding tank odors from entering the
motorhome during storage.
Your drainage and fresh water systems are
now winterized.
See instructions for removal from storage in
Section 11 - Maintenance and Storage.
