Disinfecting Your Fresh Water System - Winnebago suncruiser Owner's Manual

SECTION 7
PLUMBING
See also "Winterizing Procedure" in this
section to prepare the water filtration system for
freezing conditions. See your dealer for
replacement cartridges and O-rings.
DISINFECTING YOUR FRESH
WATER SYSTEM
To assure complete disinfection of the potable
water system, it is recommended that the
following procedure be followed on a new
system, one that has not been used for a period of
time, or one that could have become
contaminated.
This procedure is also recommended before
long periods of storage such as over winter.
Coaches with Central Filtration
System (in Water Center)
1. Open a faucet to relieve any water line
pressure, then remove the filter canister from
the filter base.
2. Remove the filter cartridge from the canister.
Seal it in a clean plastic bag and set aside for
reinstallation after disinfection procedure.
3. Pour 1 1/2 cups of household bleach (sodium
hypochlorite solution) into the empty filter
canister and screw the canister back onto the
filter base.
This solution will result in a residual
chlorine concentration of approximately 50
ppm in the water system. (If a 100 ppm
concentration is required as discussed in
step 6, use 3 cups of household bleach.)
4. Connect a hose from a city water source to
the City Water inlet and fill the fresh water
tank completely. The bleach will be drawn
into the tank when the city water is turned on
and the tank fill valve is turned to Tank Fill
position.
5. Open each faucet in the coach and run the
water until a distinct odor of chlorine can be
detected in the water discharged. Do not
forget the hot water faucets.
6. Let the system stand at least 4 hours when
disinfecting with 50 ppm residual chlorine.
(If a shorter time period is desired, then a
7-6
100 ppm chlorine concentration should be
allowed to stand in the system for at least 1
hour.)
7. Drain the fresh water tank.
8. Reinstall the filter cartridge into the filter
canister, then refill the tank with fresh water.
9. Open each faucet again and run fresh water
to flush chlorinated water from the lines.
Run the water until there is no odor of
chlorine detected in the water discharged. Do
not forget the hot water faucets. (It may take
some time to flush the water heater with
clean water.)
10. Water system disinfection procedure is done.
WARNING
Chlorine is poisonous. Recap bottle and
clean all utensils after use.
NOTE: Alternate Method – This method has the
additional benefit of disinfecting the city
water hose at the same time.
-Remove the filter cartridge from the
canister, then hand-tighten the empty
canister back onto the filter base. (Seal
the filter in a clean plastic bag and set
aside to reinstall after tank disinfection.)
-Connect the water hose to the city fill
connection on your coach. Do not
connect to city water faucet yet.
-Use a funnel to pour the required
amount of bleach into the open end of the
hose. Hold the hose up to allow enough
room for the bleach to flow into the hose.
-Connect the hose to the city water faucet
and turn on so the water will force the
bleach into the tank and continue filling
the tank with water.
Continuous Tank Disinfection
(Superchlorination)
Some RVers like to ensure continuous
sanitation of their fresh water tank by
'superchlorination'– maintaining an effective
