WINTERIZING PROCEDURE
Antifreeze Fill Procedure
(Fill plumbing lines with RV water system
antifreeze)
NOTE: Winterize tanks and waterlines by filling
them with non-toxic RV water system
antifreeze through the plumbing system.
This product is available from your
dealer and from most RV supply stores
and national retail outlets. Follow
directions on the container to determine
the correct amount to use for your coach.
Your coach is equipped with a manually
operated waterline winterization system for your
convenience in winterizing fresh waterlines.
The system features a Winterization (diverter)
valve with an antifreeze siphon tube to draw non-
toxic RV water system antifreeze into the
waterlines. This feature is located near the water
pump.
Remove Water Filters (if equipped)
1. Remove and discard the filter cartridge from
the filtered water faucet/ice maker filter
assembly below the galley sink.
(
If your coach is not equipped with a filtered
water faucet or ice maker, proceed to the next
numbered step
).
•
Twist the filter cartridge “counter-clockwise”
about a quarter-turn and pull it down and out
of the filter socket.
NOTE: The water filter head has a built-in
bypass. No separate diverter plug is
needed.
2. Remove the filter canister from the full-coach
water filtration system in the water center
compartment (if equipped) and discard the
filter cartridge.
(
If your coach is not equipped with a full-
coach water filtration system, proceed to the
next numbered step
).
NOTICE
Do not blow out Aqua-Hot Hydronic
Heating System. Failure to comply may
result in system damage.
WARNING
NEVER use automotive antifreeze/
coolant in your RV water system. Auto
antifreeze contains ethylene glycol which,
if ingested, can cause blindness and can
be fatal.
