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 pre-installed
Winterization Kit�
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
heads and toilet valve�
1� RECONNECT all lines, CLOSE all drain valves,
and REINSTALL the fresh water tank plug�
NOTICE
Do not overtighten the fresh water tank drain
plug. Overtightening may strip the threads on the
tank, plug, or both.
2� OPEN the sink and shower drains if they are
closed�
3� Ensure all the water faucets and shower heads, hot
and cold, internal and external, are OPEN�
4� Ensure the water heater bypass valves are in the
BYPASS position as mentioned in the previous
steps for winterization�
5� SET the winterize valve selector to "winterize" by
rotating it clockwise (normal flow position shown
above); see Component Locations for Winterization
on page 9-12�
6� Uncoil the hose attached to the kit, remove the
hose cap, and insert the hose down to the bottom
of the RV antifreeze container�
9-14
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, operate the toilet hand sprayer until
antifreeze is coming out� If equipped, work the
hand shower sprayer while holding it down in the
shower until antifreeze is coming out, and do the
same with the external shower head� 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�
11� Turn the winterization valve back to the normal flow
position, place the cap back on the hose, and coil it
back up for storage�
NOTICE
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.
12� Complete the final step from the previous set of
instructions on winterization�
