Optional-Additional Steps for Winterization

An additional step to winterization is to consider adding
a non-toxic RV antifreeze (approved for drinking water
systems) to the water lines using the winterize valve
to draw RV antifreeze from a container into the water
system, using the water pump�
Before beginning, read the RV antifreeze
manufacturer's label for instructions specific to the
antifreeze you plan to use� It may take a few gallons
to fill the entire system so prepare accordingly. As you
follow these steps, it will be helpful to have another
person watching and operating the faucets, shower
head and toilet valve�
1� RECONNECT all lines and CLOSE all drain valves�
2� Ensure the external sprayer port hose is
disconnected�
3� OPEN the sink and shower drains if they are
closed�
4� Ensure all the water faucets and shower heads, hot
and cold, are OPEN�
5� SET the winterize valve selector to "winterize" by
rotating it clockwise (normal flow position shown
above); see Component Locations for Winterization
on page 9-10�
6� Uncoil the hose connected to the winterize valve
and place it in the RV antifreeze container�
7� Turn the water pump ON and run it until antifreeze
starts coming out of the faucets� Once antifreeze is
running from the taps you can start closing them�
Move from one fixture to the next, shutting them
off as you go until all the lines are full� Turn the
pump OFF as you empty and transition from one
antifreeze container to the next�

8� Allow the antifreeze to flow down drains. Flush the
toilet and allow antifreeze to flow down the toilet.
If equipped, work the hand shower sprayer while
holding it down in the shower until antifreeze is
coming out� Dump any remaining small amounts of
antifreeze down a drain�
9� Shut the water pump OFF once all the lines are
full�
10� OPEN all the faucets and leave them open�
Remove all RV antifreeze spillage from all sinks,
drain pans, and faucet parts after winterizing.
Failure to do so could damage surface finishes. Do
not use water to rinse antifreeze down the drain as
it will dilute the antifreeze.
11� Complete steps 11-12 from the previous set of
instructions if not already completed�

Water Heater Winterizing

If the touring coach is to be stored during winter
months, the water lines must be drained to prevent
damage from freezing� The water heater only holds a
couple of cups of water in the heat exchanger, which is
drained with the low point drain valves;
for Winterization on page 9-10�

Restoring Service

1� Close the low point drain valve, holding tank dump
valve, and all faucets�
2� If disconnected, reconnect the water pump line�
3� Add water to the fresh water tank�
4� Turn the water pump ON�
5� Open and close faucet valves one at a time until
water runs clear signaling the RV antifreeze is
flushed out of the lines. Recheck water clarity at all
faucets�
6� Turn OFF water pump�
7� Hook up city water, open faucet valves, and
recheck water clarity�
