FILTER CARTRIDGE REPLACEMENT
CAUTION: Never remove the sump with water
pressure in the filter.
1. Close the nearest shutoff valve on the water sup­
ply pipe to the filter. To relieve pressure in the filter,
open the sink cold water faucet.
2. Turn the sump off of the filter head, to the left or
clockwise. Be careful, the sump is full of water. Do
not lose the large o- ring seal.
Note; A special wrench is available from Sears for re­
moving the sump. See the parts list on page 10,
3. Be sure the inside of the sump is clean. Cleaners are
available from Sears (see the parts list on page 10), or
use hot, soapy water.
4. Remove the wrapper from the new filter cartridge
and insert the filter cartridge in the sump. Some car­
tridges fit either way, while others fit only one way.
Observe markings on the cartridge, or on the wrap­
per.
5. Lightly lubricate the o-ring seal in the sump with
silicone grease or Vaseline. Be sure it is fully seated
in the groove.
6. Hold the sump up to the filter head aligning the
center hole in the cartridge with the protrusion on the
bottom of the head.
Note:
If the sump will not tighten up to the head you
may have the cartridge in upside down. Take the car­
tridge out and check for correct orientation,
7. Being careful not to cross- thread, turn (counter­
clockwise) the sump onto the filter head and tighten
securely.
8. Open the sink cold faucet. Then slowly open the
water supply shutoff valve and allow the filter hous­
ing to fiU,
9. Close the sink faucet. Then check for leaks between
the sump and the head.
Note:
If leaking turn off the water supply and open
the sink cold faucet to depressurize the filter. Then
disassemble the filter and check the o-ring for cuts,
flat spots, etc., and sealing surfaces for foreign mate­
rial. Clean the o-ring and lubricate "with silicone
grease or VaseUne. Carefully press into the groove in
the sump.
10. Taste and Odor Cartridges: A taste and odor car­
tridge contains activated carbon, a black powder. Af­
ter the new cartridge is installed open the filtered wa­
ter faucet and allow fine, harmless carbon particles to
purge from the cartridge. Close the faucet when you
no longer see the "fines" in the filtered water, or
approximately 2-3 minutes.
