Preparing your RV for storage is very important in climates that
experience cold weather. Follow the steps listed below at the
end of the camping season.
See page 103, Winterization Valve .
• ALWAYS winterize the fresh water system of your RV
BEFORE exposure to temperatures at or below 32°F (0°C).
◦
Damage to the water supply lines or water heater
due to freezing is not covered under warranty .
• Winterize with RV Antifreeze ONLY , no other products
should ever be added to your fresh water system.
◦
Make sure to have enough RV antifreeze to winterize
all fresh water lines. Several gallons may be required .
• BEFORE Winterizing, the Black Water, Gray Water &
Fresh Water
plumbing systems MUST all be emptied
.
See page 106 & page 98.
1. LEVEL the RV.
2. Turn OFF the Water Heater 12-volt and 120-volt interior
control switches .
