13. Now turn air pressure off and disconnect
water purge adapters. Recap the city water
connection to avoid contamination by dirt or
insects.
14. Close all drain valves and faucets to avoid
contamination by dirt or insects. Reinstall
water heater drain plug and close P-T relief
valve.
15. Pour about one cup of non-toxic RV anti-
freeze into the kitchen sink drain, bathroom
sink drain and shower drain. This prevents
any holding tank odors from entering the
coach during storage.
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.
It is not necessary to add antifreeze to the toi-
let since the flush valve will be closed.
Do not add automotive antifreeze or caustic
chemicals such as bleach or laundry deter-
gents into the toilet bowl or holding tanks.
Although these products may have a deodor-
izing effect, they may damage plastic and
rubber parts in the system.
NOTE: As an alternative to totally draining
the plumbing system, you may winter-
ize tanks and lines by pumping non-
toxic RV antifreeze through the sys-
tem. This product is available from
your dealer and from most RV supply
stores. Follow directions on the con-
STORING YOUR MOTOR HOME
tainer to determine the correct
amount to use for your coach.
See "Water System Winterization
Valve" on page 7-4 for instructions
on filling water lines with RV anti-
freeze.
If your coach is equipped with the op-
tional water heater by-pass valve, you
can fill the hot water lines with anti-
freeze solution without filling the wa-
ter heater tank. See page 8-9 for
information on the by-pass valve.
CAUTION
Leave by-pass valve handle in NOR-
MAL FLOW position if draining
water and blowing out water lines.
Place in BYPASS position ONLY
when using antifreeze solution in
water lines.
16. Place a bucket beneath the sewage drain
valve outlet and re-drain the sewage and
waste holding tanks of any clean water that
entered during "blow-out" procedure.
Close dump valves to prevent valve shafts
from rusting and to prevent entry by rodents
and insects. Refit the dust cap onto the drain
outlet.
Your drainage and fresh water systems are now
totally winterized.
17. Have the vehicle chassis completely serviced
and lubricated. Be sure radiator antifreeze
protection level is sufficient for the lowest
anticipated temperatures.
18. Wash and wax the coach.
19. Inspect all seams and seals around doors,
windows, vents, and any other joints.
Replace or repair any that are damaged.
Sealing materials and compounds can be
purchased from your dealer. Badly damaged
weather seals may need to be replaced by
your dealer.
