SECTION 7 –
PLUMBING
21. Close waste tank drain valves and refit the
dust cap onto the sewage drain outlet.
This will inhibit rust formation on valve shafts
and prevent entry and contamination by
airborne debris, insects, and rodents.
Your drainage and fresh water systems are
now winterized.
See instructions for removal from storage in
Section 11 - Maintenance and Storage.
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
(Models 36M, 40U, and 42E) or the cold
water/ice maker filter (Model 34B) located
below the galley sink.
•
Twist the filter cartridge “counter-clockwise”
about a quarter-turn and pull it down and out
of the filter socket.
•
Install the diverter plug into the cold water/ice
maker filter socket (Model 34B only) as far as
possible and twist “clockwise” one-quarter
turn until it stops.
NOTE: The filtered water faucet/ice maker filter
on Models 36M, 40U and 42E have a
built-in bypass. No separate diverter
plug is required.
2. Remove the filter canister from the Full-
Coach Water Filtration system in the water
service center and discard the filter cartridge.
After removing filter, remount the empty
canister onto the filter assembly and continue
the Antifreeze Fill Procedure.
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.
