FILTER CARTRIDGE REPLACEMENT
Stationary and Non-Stationary Filters
Use a drip pan to catch any water that may spill when
the filter housings are removed.
• Turn off faucet. Close the water line that feeds
the filter.
• Unscrew the cap and sump of the housing by
using the sump wrench that came with the filter.
Turn counterclockwise. Be careful; the sump is
most likely filled with water. Release any pressure
in the water line by turning on the cold and hot-
water faucets.
• Empty excess water into sink. Set top of filter
housing aside.
• Pull the used filter cartridge from the base and
discard.
• Clean the cap and sump of filter housing (inside
of the sump) with hot, soapy water and a soft
cloth. Rinse it very well. Do not use harsh
detergents, abrasive cleaners, or wire brushes, as
they may damage the system. (Remember that
you turned the water off at the sink you’re
working on.)
• Set the base of filter on counter (stationary
models). Remove shrink wrap.
Line up sump threads
with threads of cap and
tighten clockwise

NOTE: Make sure both O-rings are present on the filter housing. Also make sure to lubricate
O-rings with any non-petroleum oil (do not use coconut oil).
• Check the O-ring to ensure that it is positioned properly in its groove. Screw top of filter
housing (sump) onto base, turning it clockwise. Tighten with sump wrench until very snug.
Do not cross-thread or over-tighten.
• Open the water valve slowly and fill the filter.
• Turn off the faucets and check the unit for leaks.
• Run the water for 5-10 minutes to clear out carbon particles that may have settles in the
cartridge. This should be repeated as necessary.
