Remove Water Filters
Before pumping RV antifreeze into water
system, remove water filter cartridges (if
equipped.)
1. Remove and discard the filter cartridge from
the cold water filter assembly below the galley
sink. (

filtered cold water, continue to next numbered
step.

• Place a container beneath the filter to catch
any water remaining in the waterlines during
filter removal.
• Twist the filter cartridge counter-clockwise
(to the left) about one-quarter turn, then pull
it down and out of the filter socket.
• Install the diverter plug into the filter socket.
Insert plug up into the filter socket as far as
possible and twist clockwise (to the right)
one-quarter turn until it stops.
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.
)
After removing filter, remount the empty
canister onto the filter assembly and continue
the antifreeze fill procedure.

3. Turn Winterization Valve 1 to “Water Heater
Bypass” position to avoid filling water heater

CAUTION
Leave Bypass valve handle in “Normal
Operation” position if draining water and
blowing out waterlines. Place in “Bypass”
position ONLY when using antifreeze
