Disinfecting Your Fresh Water System - Winnebago FORZA Series Manual

• Unscrew the canister from the filter head.
(There will be water inside the canister).
• Remove the large O-ring seal from the
canister. Check seal for damage, wipe clean,
and set aside. Discard the used filter cartridge.
• Wash the inside of the canister with dish soap
and warm water using a nonabrasive sponge
or cloth. Rinse thoroughly.
• Fill canister about 1/3 with clean water and
add a couple of tablespoons of household
bleach, then scrub with a sponge or brush to
disinfect. Rinse thoroughly.
• Lubricate the O-ring with clean silicone
grease to ensure a proper watertight seal, then
place back into the groove at the bottom of the
canister threads.
NOTE: The O-ring should be replaced every
third cartridge change to ensure proper
sealing. See your dealer for replacement
cartridges and O-rings.
• Insert a new filter cartridge into the canister,
then hand tighten the canister securely onto
the filter head. DO NOT OVER-TIGHTEN.
• Turn the Fresh Water Valve to Normal
position. Next open a faucet inside the
motorhome or the exterior shower, then turn
city water on SLOWLY to allow the canister
to fill with water.
• Thoroughly flush the filtration system by
running the water for twenty (20) minutes.
• Check for leaks.
See "Winterizing Procedure" in this section to
prepare the water filtration system for freezing
conditions.
DISINFECTING YOUR FRESH
WATER SYSTEM
(As required by NFPA
Recreational Vehicles)
–For motorhomes with Full-Coach Water
Filtration System
To ensure complete disinfection of the potable
water system, it is recommended that the
following procedure be followed on a new
®
1192 Standard on
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.
Disinfecting with Gravity Fill
–If Equipped
1. Prepare a chlorine solution using 1 gallon of
water and 1/4 cup of household chlorine
bleach (sodium hypochlorite solution). With
tank empty, pour chlorine solution into the
tank through the gravity fill port.
Use 1 gallon solution for each 15 gallons of
tank capacity. This procedure will result in a
residual chlorine concentration of 50 ppm in
the water system.
NOTE: If a 100 ppm concentration is desired,
use 1/2 cup of household bleach with 1
gallon of water to prepare the chlorine
solution. One gallon of this solution
should be used for each 15 gallons of
tank capacity.
WARNING
Chlorine is poisonous. Do not misuse.
Recap bottle and clean all utensils after
use.
2. Complete filling of tank with fresh water.
3. Open each faucet in the motorhome and run
the water until a distinct odor of chlorine can
be detected in the water discharged. Do not
forget the hot water faucets.
4. Let the system stand at least 4 hours when
disinfecting with 50 ppm residual chlorine.
If a shorter time period is desired, then a 100
ppm chlorine concentration should be
allowed to stand in the system for at least 1
hour.
5. Drain the water tank and refill with fresh
water.
