FILTER CARTRIDGE / USEFUL LIFE / REPLACEMENT
FILTER CARTRIBGE LIFE
Several variables determine how long a cartridge will
last These include:
1. how much water you use
2 how much sediment, taste and/or odor, or other un­
wanted substance, is in the water
Use the following information as a guide. However,
no matter which type of cartridge you are using, you
will know it is time to replace it when you first no­
tice the return of the unwanted substance in your
water.
Sediment Cartridges: Average cartridge life, when
filtering water to 1 faucet, is about 6 months This aver­
age time varies depending on the type of sediment
cartridge
Filtering sediments, you will know it’s time to replace
the cartridge when water pressure to the faucet drops
Taste and Odor Cartridges: Filtering water to a
single faucet, the filter cartridge may last for 6 months
or more If the cartridge is also for lead or chemical
contaminant removal, it is more important to replace
it frequently
FILTER CARTRIDGE REPLACEMENT
CAUTION: Never remove the sump with water
pressure in the filter.
1, Close the nearest shutoff valve on the water
supply pipe to the filter. To relieve pressure in
the filter, open the sink cold water faucet, or press
the vent vaive (Deluxe models - some water may
leak out) on the top of the head
2. Turn the sump off of tiie filter head, to the left or
clockwise Be careful, tlie 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 die parts list on page 9.
3. Be sure the inside of the sump is clean. Cleaners are
available from Sears (see the parts list on page 9), or
use hot, soapy water,
4. Remove the wrapper from the new filter cartridge
and insert die filter cartridge in the sump Some car­
tridges fit either way, while odiers fit only one way,
Observe mar kings on the cartridge, or on die wrapper
5. Lightly lubricate the o-ring seal, in die sump, with
silicone grease or Vaseline. Be sure it is fully seated in
the groove,
6. Hold die sump up to the fdter head, aligning the
center hole in the cartridge with the protrusion on the
bottom of the head,
Note: If die 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 die filter housing
to fill. While it is filling, press the filter vent valve (De­
luxe models) to release air in the filter,
9. Close the sink faucet Then, check for leaks be­
tween die sump and the head.
Note- If leaking, turn off die water supply and open
the sink cold faucet to depressurize die filter (or press
the vent valve on Deluxe models). Then, disassemble
the filter and check the o-ring for cuts, flat spots, etc ,
and sealing surfaces for foreign material. Clean the o­
ring and lubricate with silicone grease or Vaseline,
Carefully press into the groove in die sump
10. Taste and Odor Cartridges: A taste and odor car­
tridge contains activated carbon, a black powder.
When new, open the filtered water faucet and allow
fine, harmless carbon particles to purge from the car­
tridge, Close the faucet when you no longer see the
“fines" in the filtered water.
