FILTER CARTRIDGE REPLACEMENT
Complete the following steps to replace the cartridges:
CAUTION: Never remove sumps with water pressure
in the filter system.
1. Close the water supply shutoff valve (See Fig. 2 on
Page 5) to the filter. Open the filtered water faucet to
relieve pressure in the system.
2. Use the sump removal wrench, included, to turn the
sump to the left to loosen it from the filter head. Be
careful - the sump is full of water. Do not lose the
large o-ring seal.
3. Dispose of the old cartridge in a proper manner.
4. Make sure the inside of the sump is clean. Use hot,
soapy water and rinse thoroughly.
5. Remove the wrapper from the new cartridge and
insert filter cartridge into the sump. Some cartridges
fit either way, while others fit only one way. Observe
markings on the cartridge or wrapper.
NOTE: If you are using filter numbers 42-38480 and
42-34373, place filter 42-38480 (Sediment*) in the
Filter I position and place filter 42-34373 (Taste &
Odor) in the Filter II position (See Fig. 15).
6. Lightly lubricate the o-ring seal in the sump with sili-
cone grease. Be sure it is fully seated in its groove.

7. Hold the sump up to the filter head, aligning the cen-
ter hole in the cartridge with the protrusion on the
bottom of the head.
NOTE: If the sump will not tighten up to the head, and
you are using cartridges other than 42-38480 and
42-34373, you may have the cartridge in upside
down. Take the cartridge out and check for cor-
rect orientation.
8. Being careful not to cross-thread, turn the sump to the
right onto the filter head and tighten securely.
9. Repeat steps 2 through 8 for the other filter.
10. Open the filtered water faucet. Then, slowly open
the water supply valve and allow the filter housing
to fill.
11. Close the filtered water faucet. Check for leaks
between the sumps and the heads.
12. Remove and replace the timer battery. See "Change
Battery" on Page 9.
Taste and Odor Cartridges: A taste and odor cartridge
contains activated carbon, a black powder. When new,
open the filtered water faucet and allow fine carbon par-
ticles to purge from the cartridge. Close the faucet when
you no longer see the "fines" (carbon particulates) in the
filtered water, or approximately 10 minutes.
