Filter Cartridge Replacement
CAUTION: Never remove the sumps when water pressure is in the water
filtration system.
Close the water supply saddle valve to the filter. (See the Installation
Instructions for saddle valve location.) Press the vent valve on the top
of the filter I head to relieve the pressure in the system, or open the
filtered water faucet.
Remove the sump, using the sump wrench tool provided, from the
filter head, by rotating the sump as shown in the below illustration.
Be careful, the sump may be full of water. Be sure to keep the large
o-ring seal.
If you are replacing a filter cartridge, remove and discard the used filter
cartridge.
Be sure the inside of the sump is clean. Thoroughly wash the inside of
the sump with hot, soapy water and rinse.
Remove the wrapper from the new filter cartridge and insert the filter
cartridge in the sump. Some cartridges fit either way, while others fit
only one way. Observe markings on the cartridge.
NOTE: The water filtration system uses two different types of filter cartridges.
Be sure to install them correctly.
The sediment/taste and odor filter (FXUS) should always be placed in the
filter I sump.
