▲ Your water softener will remove hardness minerals and “clear water” iron from water, up to the limits shown on page 4-1. It will not remove other types of iron, acids, tastes and odors, etc. It will not purify pol luted water or make it safe to drink.

▲ Protect the softener and piping from freezing. Dam age from freezing voids the softener warranty. See page 3-3.

CAUTIONS

PLEASE READ AND COMPLY WITH THE FOLLOWING GUIDES TO PREVENT DAMAGE TO THE SOFTENER OR OTHER PROPERTY, PERSONAL INJURY, OR POS SIBLE FATAL SHOCK.

▲ THIS SOFTENER WORKS ON 24 VOLTS ONLY. BE SURE TO USE ONLYTHE TRANSFORMER INCLUDED,

AND PLUG IT INTO A HOUSEHOLD 120V OUTLET. IF TRANSFORMER IS REPLACED, USE ONLY THE AU THORIZED SERVICE CLASS, II, 24 VOLT, 10 VA TRANSFORMER.

▲ Unplug the transformer right away if the power cable should become damaged or frayed. Make re

pairs before plugging back into the power outlet.

▲ Always unplug the softener from electrical power

before removing outer valve covers.

▲ This system is not intended to be used for treating water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.

D. SANITIZE THE WATER SOFTENER

JJJJJJJJJJJJJJJJJJJJJJJJJ. JJJJJJJJJJJJJJJJJJJJJJJJJ JJJJJJJJJJJJJJJJJJJJJJJJJ.

WATER SOFTENER START UP

Care is taken at the factory to keep your water soft ener clean and sanitary. Materials used to make the softener will not infect or contaminate your water supply, and will not cause bacteria to form or grow. However, during shipping, storage, installing and operating, bacteria could get into the softener. For this reason, sanitizing as follows is suggested® when installing.

The first time you sanitize your softener, be sure to do all steps in the installation manual, and on pages 1-2,1-3 and 1-4 of this manual first.

Gift the salt hole cover and use a pail to fill the salt storage tank with up to 3 gallons of water

(approximately 3 inches). Remove the brinewell cover (FIG. 3) and pour

about 3/4 ounce, or 1 to 2 tablespoons, of com mon 5.25%, unscented, household bleach (Clorox, Ginco, BoPeep, White Sail, Eagle, etc.) in the softener brinewell. Replace the brinewell cover.

Open the bypass valve and press the ON/OFFHOGD button and hold for 3 seconds to start a re charge. This first recharge does several things.

• Dt fills the salt tank to the water level needed.

• Dt gets all the air out of the resin tank.

• Dt prepares the resin bed (see page 2-4) for ser vice.

Notes: This recharge takes about 2 hours, depending on the salt type setting (page 1-4).

You can sanitize the softener with or without salt in the storage tank.

® Recommended by the Water Quality Association. On some water supplies, the water softener may need periodic

disinfecting.

WATER SOFTENER START UP

E. FILL THE STORAGE TANK WITH SALT

Brine (salt dissolved in water) is needed for each and every regeneration. The water for making brine is metered into the salt storage tank by the softener. However, you must keep salt in the tank, but it is not necessary to keep it full. In humid areas, it is best to fill the storage tank one quarter to one half full, and to refill it more often. Salt bridging (see page 3-1) occurs more often when conditions are humid.

Fill the tank with NUGGET or PELLET water soft ener salt. DO NOT use rock salts, as they have dirt and sediments that will stop the softener from working.

Before filling, be sure the brinewell cover is in place on the top of the brinewell. Salt storage capacity is shown on page #-1. Be sure to set the salt monitor system (see page 2-1).

POTASSIUM CHLORIDE, alternate to salt: The de sign of this softener allows for the use of potassium chloride in place of salt (sodium chloride).

1) Place only one bag of KCl in your softener at a time (the salt storage tank should contain no more than 60 pounds of KCl at any one time).

2) A softener using KCl should not be placed in areas with temperature fluctuations and high hu midity (KCl will harden in these environments and may make the softener inoperable).

3) Check the brine tank and brinewell (black tube in salt storage tank) monthly. Df hardening is present, pour small amounts of warm water on hardened areas until they loosen.

4) If you do use potassium chloride, see page 1-4 to set the timer for its use.

Note: The salt monitor system, page 2-1, is cali brated to the density of nugget or pellet water soft ener salt. The monitor will not work as accurately with other types of salt including rock and solar.

Sodium information: Water softeners using sodium chloride for regeneration add sodium to the water. Persons who are on sodium restricted diets should consider the added sodium as part of their overall sodium intake. For example, if your water supply is 15 grains hard, you would have to drink 3 quarts of softened water to consume 335 milligrams of so dium. That is equivalent to eating 2-1/2 slices of white bread.

WATER SOFTENING SALT WITH IRON REMOV ING ADDITIVES — Some salts have an additive to

help the softener handle iron in the water supply. These salts may be used if your water supply has a high iron content. Dt is recommended to use Sears

Persons who are concerned about their drinking water should consider a Kenmore Drinking Water System that will remove or reduce in excess of 90% of the sodium and other drinking water contami nants.

You have now finished the water softener start up. After the sanitizing recharge, on

page 1-5, the softener will be giving you soft water. Please read pages 2 - 4,2 - 5 and 2 - 6 in section 2 to understand how the softener works to continue to give you soft water.

*Note: If the CLEAN feature is set to ON, a cleaning back wash (CGEAN and Bkwsh or Rinse flashes in the dis play, along with the minutes of the clean cycle re maining) precedes the recharge.

Sometimes, a manually started regeneration (recharge) may be desired, or needed. Two exam ples are:

- You have used more water than usual (guests visiting) and you may run out of soft water before the next timer started regenera tion.

- You did not refill the softener with salt before it was gone. After you refill with salt:

You can start a regeneration right away, or you can set the timer to regenerate at the next 2:00 AM (or other preset recharge time). Do the following.

^ SALT MONITOR SYSTEM

The faceplate timer has a low salt monitor with an indicator light to remind you to refill the storage tank with salt. To set this monitor system:

Lift the salt hole cover and level the salt in the storage tank.

The salt level decal, on the brinewell inside the tank, has numbers from 0 to 8 (see drawing be low). Observe the number the leveled salt is at or closest to.

Now, press the SALT LEVEL ADJUST button until black bars display up to the salt level num ber. For example, the pictures below show the salt level at 6.

Finally, set the level you want the low salt indi cator light to come on. Press the SIGNAL LIGHT ADJUST button until a (Y) shows opposite this number. In the example below, the light will come one when the stored salt drops to level 2. At level 2, the storage tank is about 1/3 full. This is the lowest you should allow the stored salt level to drop to.

If you want to turn the salt monitor off, press the SIGNAL LIGHT ADJUST button until OFF shows above.

Note: For accurate salt monitor operation, always use nugget or pellet water softener salt. See page 1-6.

If potassium chloride is used, be sure to adjust the timer to the KCl setting on page 1-4.
