WATER FILTER START-UP
!
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 suggestedO
when installing.
1.
Press and HOLD button []
RCHG
on the face plate until RCHG
AM
12:00
begins to flash in the display
[su
(12:00
AM began
to flash
when the transformer
was plugged in).
The
valve motor begins to run to advance the filter
into the "fill" cycle.
Water flows
through the
plastic tubing and you will see the potassium
permanganate
bottle begin to fill.
a.
As the bottle
begins
to fill with water, press
button []
again.
In about 1 minute, you will see
a slow flow of water begin out the valve drain
hose.
b,
Wait
about
30 seconds,
then
press
button
[]
once more. As the valve repositions
again, a
fast flow from the filter drain hose begins. This is
the filter "backwash"
cycle.
Allow t;,a filter to
backwash for several minutes.
¢.
Press button []
to advance the filter frem back-
wash to "fast rinse" cycle. (Water from the drain
hose stops momentarily, then begins again).
2.
After about 2 minutes of fast rinse, PUT THE
BYPASS VALVE(S) IN BYPASS POSITION (SEE
FIG. t0, PAGE 18). Then press button[]
once
again to return the filter to "service"
position.
DOING THIS RELEASES
WATER PRESSURE
IN THE FILTER.
3.
Carefully remove the large plastic clip at the filter
valve inlet (see Key No. 62, page 30).
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.
(_ Recommended by the Water Quality Associal_on. 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 under trade names such as Perchloren 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.

SLOWLY,
reposition
the bypass
valve(s)
to
service...
FIG. 10, page 18. Open the nearest
_water
faucet until you can smell chlorine,
then close.
7.
Again, put the bypass valve(s) in bypass posi-
tion. Allow the filter to stand idle for about 45
minutes, while the chlorine sanitizes.
NOTE:
During this time, go to pages 7 and 8 to make the
timersettings.
If needed, adjustthe feedervalve
tube
for potassium permanganate
use, page 9.
Then,
complete the following steps.
8.
After 45 minutes, return the bypass valve(s) to
service position.
9.
Repeat steps 1, laand
lbtoadvancethefilterto
backwash.
The timer will automatically advance
the filter through
the backwash
and fast rinse
cycles,
during
which
the sanitizing
bleach
is
flushed to the drain.
NOTE:
The backwash
and fast rinse cycles take abut 25
minutes.
When over, the timer automatically
returns
the filter to service
(water flow from the drain hose
stops).
10.
Open house filtered water faucets and allow to
run until the chlorine odor is gone.
