About the water filtration system.
Filter Cartridge Installation or 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 illustration in the Installation Overview
section for location of the water supply valve.)
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 may use two
different types of filter cartridges. Be sure to
install them correctly. Filter I
cartridge should
always be placed in the
Filter I
sump.
Filter II
cartridge should always be placed in the
Filter II
sump.
See page 3 for a complete list of filter
performance characteristics.
