10.SANITIZING THE WATER FILTER

Care is taken at the factory to keep your water filter clean and sanitary. Materials used to make the filter 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 filter. For this reason, sanitizing as follows is suggestedG when installing.

on the face plate until RCHG	_cMHG12:00
Press and HOLD button []
begins to flash in the display	su
(12:00 AM began to flash

when the transformer was plugged in). Water will begin to run from the drain hose as the filter valve moves into backwash position.

After 5 to 10 minutes, press [] again to move the filter valve into fast rinse position (water stops, then begins to run from drain hose again).

mIn about 2 minutes, PUT THE BYPASS VALVE(S) IN BYPASS POSITION (SEE FIG. 8, PAGE 18). Then, press button [] once again to return the filter valve to service position. Doing this re- leases water pressure in the filter.

3.Carefully remove the large plastic clip at the filter valve inlet (see Key No. 41, page 26). Pull the valve adaptor from the filter inlet.

NOTE:

If bypass valve, Sears Stock No. 42-3437 is installed, or if plumbing is too rigid to move, also disconnect the outlet side and move the filter away from plumbing.

4.Put 1 teaspoon (0.1 ounce) of calcium hypo- chlorite into the valve inlet as far as possible.

NOTE:

You can buy calcium hypochlorite in tablet or granu-

lar form using trade names such as Perchloron and HTH.

m Be sure the valve inlet is clean, for a good sealing surface for the valve adaptor o-ring. Then, reconnect plumbing to the filter. AFTER INSTALLING THE LARGE PLASTIC CLIP, PULL OUTWARD ON THE VALVE ADAPTOR TO BE SURE IT'S PROPERLY HELD IN PLACE.

6.SLOWLY, reposition the bypass valve(s) to serv- ice... FIG. 8, page 18. Open the nearest_ water faucet until you can smell chlorine, then close.

m Again, put the bypass valve(s) in bypass posi- tion. Allow the filter to stand idle for about 45 minutes, while the chlorine sanitizes.

1 After the 45 minutes, return the bypass valve(s) to service. Then, press face plate button [] to start a backwash. While the filter completes this automatic backwash and fast rinse . .. takes about 35 minutes.., turn to page 7 and make the timer settings.

1 When the backwash/fast rinse is over (water flow to drain stops), open filtered water faucets until chlorine odor is gone, then close the faucets.

C)Reoommended by the Water Quality Association. On some water supplies, the water filter may need periodic disinfecting.
