Replacing the Cold Water Filter
Cartridge
You should replace the filter cartridge every
season and when water flow from the faucet is
too slow for convenience. The cartridge must be
replaced at least every 12 months.
Further Information
See the water filter manufacturer’s operation
information in your InfoCase for filter cartridge
replacement.
DISINFECTING YOUR FRESH
WATER SYSTEM
(As required by NFPA
®
1192 Standard on
Recreational Vehicles)
To ensure 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.
Disinfecting with Tank Fill
When disinfecting through the tank water fill,
an external cartridge-type water filter assembly
must be connected in-line between the city water
hose and the tank fill inlet to add disinfecting
solution to the tank. These filters are commonly
available at most RV supply stores.
NOTE: If you do not have an in-line cartridge
filter, see City Water Hose/Tank
Disinfection following this procedure for
an alternate method of adding bleach
solution to your tank.
1. Turn off Heating System and allow to cool.
See “Heating System - Furnace and Indirect
Water Heating” in
Section 4 - Appliances and
Systems.
2. Turn “Winterization Valve 1” to bypass water
heater to prevent filling the water heater tank
with a high concentrate of chlorine.
3. Remove the filter cartridge and pour 1/4 cup
of household chlorine bleach (sodium
hypochlorite solution) for each 15 gallons of
tank capacity into the empty filter canister,
then 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
desired, use 1/2 cup of household bleach for each
15 gallons of tank capacity).
The bleach will be
drawn into the tank when the city water is turned
on.
4. Fill the tank completely, then 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.
