Filter Cartridge

FILTER CARTRIDGE LIFE

Several variables determine how long a cartridge will last. These include:

￿How much water you use.

￿How much sediment, taste and/or odor, or other unwanted 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 notice the return of the unwanted substance in your water. Filter cartridges are available from your local Sears store and www.sears.com.

The filter cartridges require replacement 3 or 4 times a year when used for whole house filtering. Average car- tridge life when filtering water to one faucet is 6 months or more. This average time varies depending on the type of cartridge and water conditions.

SEDIMENT CARTRIDGES: Filtering sediments, you will know it's time to replace the cartridge when water pressure drops at house faucets.

TASTE & ODOR CARTRIDGES: Filtering taste and odor, you will know it's time to replace the cartridge when the taste and odor returns. If the cartridge is also for sediment removal, you could notice a pressure drop before the return of taste and odor.

FILTER CARTRIDGE INSTALLATION/ 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, press the vent valve on top of the filter head (See Figure 14) or open a cold water faucet after the filter. Some water may leak out of the vent valve as pressure is being relieved.

2. Turn the sump to the left to remove from the head (See Figure 14). Be careful, as the sump is full of water. Do not lose the large o-ring seal.

3. Be sure the inside of the sump is clean. Thoroughly wash with warm, soapy water and rinse.

4. Remove the wrapper from the new filter cartridge and insert the filter cartridge into the sump. Some car- tridges fit either way, while others fit only one way. Observe markings on the cartridge, or on the wrapper.

5. Lightly lubricate the o-ring seal, in the sump, with sili- cone grease. Be sure it is fully seated in the groove.

6. 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, you may have the cartridge in upside down or not centered in the sump. Take the cartridge out and check for correct orientation.

7. Being careful not to cross-thread, turn the sump to the right 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 fill. While it is filling, press the filter vent valve to release air in the filter.

9. Close the sink faucet. Then, check for leaks between the sump and the head.

NOTE: If a leak is occurring, turn off the water supply and open the sink cold faucet to depressurize the filter (or press the vent valve). Then, remove the sump 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. 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. When new, open a filtered water faucet and allow fine carbon particles to purge from the cartridge.

Close the faucet when you no longer see the “fines” in the filtered water.

11. Retighten the sump 7 days after replacing filter.
