General Filter Maintenance
drawing in Figure 31, place in position along with
the top distributor.
13
. Carefully, lower the valve assembly onto the tank
adaptor. Install the clamps and retainers, making
sure they are securely fastened.
14
. Reconnect filter valve inlet and outlet to installation
adaptors, or bypass valve, and put clips back on,
making sure they are snapped securely in place.
15
. Do steps 6 and 7 on pages 9 and 10. The filter will
complete the backwash you started in step 1, above.
NOTE:
Backwashing removes carbon ‘‘fines’’ (too
small or fine particles) from the new mineral.
If the filtered water still contains fines, after
the backwash, repeat step 1 to initiate another
backwash, or open faucets and let the water
run until clear.
REPLACING MINERAL IN THE TASTE & ODOR FILTER
The activated carbon mineral adsorbs tastes and/or
odors in the water supply. How long it lasts depends
on how much water is used, and other conditions.
Average life of the mineral is about one year. When
tastes and/or odors return in your filtered water, min-
eral bed replacement is needed.
MINERAL REPLACEMENT
1
. Press the Touch/Hold button until “RECHARGE
NOW” begins to flash in the time display.
2
. Wait until water begins to flow from the valve drain
hose. Then, place the bypass valve(s) in “bypass”
position. Refer to figures 6 and 7 on page 7.
IMPORTANT:
To relieve pressure in the tank, be sure
to do steps 1 and 2 as instructed.
3
. Unplug the power supply at the wall outlet.
4
. Carefully remove the clips at the filter valve inlet
and outlet. Then, separate the filter from the instal-
lation adaptors, or from the bypass valve (Figure 8,
page 8).
5
. Remove the two clamp retainers and two clamp
sections that hold the valve to the tank. Lift the
valve assembly up and off the tank.
6
. Remove three o-ring seals and the top distributor
from the tank. Inspect the o-rings to be sure they
are reusable (see repair parts pages). Set the
parts safely aside so they won’t be lost or broken.
CAUTION:
Handle the tank carefully when doing the
following step. Do not attempt to lift the
tank. Wet carbon is very heavy.
7
. At a floor drain, carefully tip the tank over to empty
the contents. Catch the carbon in a burlap sack or
other suitable container. Remove the bottom dis-
tributor when you are able to do so.
8
. Flush the inside of the tank with fresh water to thor-
oughly clean.
9
. Stand the tank upright and replace the bottom dis-
tributor. Plug the end of the bottom distributor tube
with a rag.
10
. Use a large neck funnel to add the new bed.
First, add 17 lbs of gravel, followed by 10 lbs of
filter sand. Finally, making sure the bottom dis-
tributor is centered, add 1 cu. ft. of activated car-
bon mineral into the tank. Use water sparingly to
assist the flow of mineral through the funnel.
11
. Use water to flush the tank top opening. It must
be clean for good o-ring sealing surfaces.
12
. Be sure the three o-ring seals are lubricated (use
silicone grease). Then, referring to the inset
