Winterizing with Antifreeze method
It may be easier to winterize the motor home with another person to assist you.
1. Level the motor home and drain the fresh water plumbing system.
2. Turn the water valves OFF on each side of the water filter canister. The canister is
located behind the utility center. Unscrew the canister and remove the filter.
attach the empty canister and turn the water valves ON (refer to the Water Purification
section).
3. Water heater power switches (12V GAS & 120V ELECTRIC at the command center)
should be turned OFF. Gas valve at the water heater should be turned OFF. The
tankless water power switch is located outside the RV.
4. Turn the water heater bypass valves (if so equipped) to the BYPASS position. Tankless
water heater will not have bypass valves.
5. Move the valves to the "Sanitize/Winterize Lines" position. The low point drains must
be closed for the antifreeze to siphon through the lines.
6. Attach the short hose supplied with the motor home to the fresh water connection inlet
and insert the other end of the hose into a gallon container of RV antifreeze (this quantity
should be enough to winterize the motor home). To assist the siphoning process, put the
container on a surface approximately two feet above ground level.
7. Turn the water pump ON. If the water pump fails to self-prime, temporarily open the
low point drains. Close the low point drains as soon as the water pump primes (RV
antifreeze will begin draining out)] and before continuing to the next step.
8. Open the hot water line on all the faucets (kitchen, lavatory, shower and outside shower)
until RV antifreeze begins to flow continuously (refer to "Winterizing Dishwasher and
Winterizing Washing Machine instructions in this section if applicable).
9. Close the faucet hot water lines and repeat with the cold water lines on all the faucets.
Flush the toilet a couple of times until you see antifreeze in the bowl.
When you are done adding RV antifreeze
10. Remove the short hose from the container of RV antifreeze.
11. To prevent staining, wipe the RV antifreeze out of the sinks, shower (or tub) and toilet
using a soft, dry cloth.
If needed, contact your RV dealer for assistance.
Winterizing the Dishwasher (if so equipped)
While you are putting antifreeze in the water lines follow these instructions to winterize the
dishwasher:
1. Use the dishwasher remote control to unlock the dishwasher. Open the dishwasher and
select RINSE.
2. Close the dishwasher and the rinse cycle should begin. This will bring antifreeze into
the dishwasher through the water lines.
3. Pause the dishwasher with the remote (wait for 3 beeps), open the dishwasher and add
several cups of antifreeze into the tub.
4. Close the dishwasher, re-start it with the remote, then press and hold the button on the
remote until you hear a quick double beep. The dishwasher will drain the antifreeze
into the pump assembly.
