Plumbing Systems
It is important to
read all instructions
& understand
each step before
beginning the winterization
process. It may be easier
to winterize the RV with
another person to assist
you. If needed, contact
your dealer for assistance.
Both automotive antifreeze
(ethylene glycol) and
windshield washer anti-
freeze (methanol) are
poisonous.
NEVER use these products
in your fresh water system.
They are harmful and may
be fatal if swallowed.
BEFORE Winterizing, the Fresh Water plumbing systems
& Black Water, Grey Water Tanks MUST all be emptied.
• See page 19 & page 106 in your Owners Manual.
1. LEVEL the RV.
2. Turn OFF the Water Heater 12-volt and 120-volt
