CAUTION

FLOW position if draining water and
blowing out waterlines. Place in BYPASS
position ONLY when using antifreeze
solution in waterlines.

WINTERIZING PROCEDURES

You can winterize the water and plumbing
system of your coach using one of the following
two methods – 1) Blow out waterlines using
compressed air or – 2) Fill waterlines with RV
water system antifreeze.
Method 1 – Blow Out Procedure
(Drain and purge waterlines using
compressed air)
1. Level the Motor Home. If the coach is not
level, there may be "low points" in waterlines
that can trap water in the lines and prevent it
from draining properly.
2. Drain Fresh Water Tank and Waterlines.
Open all waterline drain valves and drain
fresh water tank. (See "Water System Drain
Valve Locations" chart at end of this section
for locations of drain valves on your model.)
3. Drain Exterior Shower/Wash Station.
Open exterior shower knobs and lay shower
head on ground as shown to drain any water
left in the shower line. Also place the tip of
your finger into the city water inlet and gently
press the backflow valve "button" in the
center of the inlet to drain any water trapped in
the inlet line.

4. Remove the Water Filter Cartridge (if
equipped). Remove the filter cartridge from
the filter assembly below the galley sink.
(If your coach is not equipped with a filtered
water faucet, proceed to the next numbered
step.)
Water Filter Assembly below Galley Sink
• Twist the filter cartridge counter-clockwise
(left) about a quarter-turn and pull it down and
out of the filter socket.
5. Remove Full-Coach Water Filter (if
equipped). 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.)
