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.

Press and HOLD button [] _cMHG12:00
on the face plate until RCHG
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 5to 10 minutes, press [] again to move the
filter valve into fast rinse position (water stops,
then begins to run from drain hose again).
m
In 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.

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.
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.
Again, put the bypass valve(s) in bypass posi-
tion. Allow the filter to stand idle for about 45
minutes, while the chlorine sanitizes.
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 7and make the
timer settings.
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.
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.
