FILTER CARTRIDGE / USEFUL LIFE / REPLACEMENT

FILTER CARTRIDGE LIFE

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

1.where the water filter is installed (filtering all house water, or just to 1 faucet)

2.how much water you use

3.how much sediment, taste and/or odor, or other un6 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 1ou fir￿t no2 tice the return of the unwanted substance in 1our water.

Sediment Cartridges: Cartridge life, when filtering water to 1 faucet, is about 6 months maximum. Car6 tridge life is less when filtering all house water. This time varies depending on the type of sediment car6 tridge.

Filtering sediments, you will know it's time to replace the cartridge when water pressure drops to the single faucet, or to the entire house supply.

Taste and Odor Cartridges: Filtering water to a single faucet, the filter cartridge may last for 6 months or more. Cartridge life is less when filtering all house water. If the cartridge is also for lead or chemical con6 taminant removal, it is more important to replace it fre6 quently.

Phosphate Cartridge: The cartridge is filled with pure food grade phosphate crystals. The crystals slow6 ly dissolve, and the phosphates coat the insides of the plumbing. This coating keeps the slightly acid or cor6 rosive water away from the inside surfaces to help stop rusting, staining and scale.

In addition to the previously mentioned variables, wa6 ter temperature, hardness and pH are all factors in how fast the crystals dissolve. After 4 or 5 months, check the cartridge to see how many crystals remain. Replace the cartridge, or refill with crystals if needed (see page 11). Otherwise, check the cartridge again af6 ter several more months. After checking a few times, you will know about how fast the crystals are dis6 solved, and the frequency replacement of the car6 tridge or crystals is needed.

TO REMOVE

1.Turn the filter handle to the OFF or BYPASS position, to relieve pressure in the filter. It is normal for some water to leak out.

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 re6 moving the sump. See the parts list on page 11.

3.Be sure the inside of the sump is clean. Cleaners are available from Sears (see the parts list on page 11), or use hot, soapy water.

4.Remove the wrapper from the new filter cartridge and insert the filter cartridge in the sump. Some car6 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 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.
