Replacing the Full-Coach Water
Filtration Cartridge
Replace the filter cartridge after 1,000 gallons
of usage or sooner if water flow from faucets is
noticeably reduced.
•
Turn off the water supply and relieve water
line pressure by opening a faucet.
•
Remove the filter canister from the filter head.
Use the filter wrench supplied to loosen the
filter canister.
•
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 coach
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
