General Filter Maintenance
8
. Plug the end of the bottom distributor tube with a
rag. Then, use a large neck funnel to add new
mineral into the tank.
CAUTION:
Do not pour mineral into the bottom dis-
tributor tube.
CAUTION:
Do not overfill the tank. Freeboard area
(Figure 31, next page) is needed for prop-
er backwash cleaning of the mineral bed.
9
. Use water to flush the tank top opening. It must be
clean for good o-ring sealing surfaces.
10
. Be sure the three o-ring seals are lubricated (use
silicone grease). Then, referring to the inset
drawing in Figure 31, place in position along with
the top distributor.
11
. Carefully, lower the valve assembly onto the tank
adaptor. Install the clamps and retainers, making
sure they are securely fastened.
12
. 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.
13
. Do steps 6 and 7 on pages 9 and 10. The filter will
complete the backwash you started in step 1, above.
DETERMINE MINERAL ADDING FREQUENCY
At this time, take a yard stick or tape measure
and measure down to the top of the mineral bed.
Use a flashlight so you can see the top of the
bed. Measure inches as shown in Figure 31 (see
next page).
If the measurement is 32” or less, over half of the
mineral bed remains. You could wait for 9-10
months before refilling the next time (assuming
water usage remains about the same).
If the measurement is 38” or more, less than 1/4
of the bed remains. It may be better to add min-
eral more often than every 6 months.
ADDING MINERAL TO THE NEUTRALIZING FILTER
The neutralite/magnesium oxide mineral slowly dis-
solves to neutralize acid in the water. If the filter is
not serviced, all of the mineral would dissolve. How
fast it dissolves depends on the pH of the water, how
much water is used, and other water conditions.
Because of the variables, it is difficult to determine
exactly when to add more mineral. When you have
had the filter for a period of time, experience will tell
you when to add more mineral. You can use the
instructions following step 7 as a guide to determine
when to refill the next time.
ADDING MINERAL
Refill the filter with mineral the first time about 6
months after installation. See step 7 to determine the
next time to refill.
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 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.
7
. To make room in the tank for new mineral, use a
hose to siphon water out. Run the hose about 36”
down the inside of the bottom distributor. Be care-
ful not to damage the top edge of the tube.
PROTECT THE FILTER FROM FREEZING
If the filter is installed where it could freeze (summer
cabin, lake home, etc.), you must drain all water from
it to prevent possible freeze damage. Be sure to pro-
tect your filter from freezing temperatures.
The filters require a minimum of care. A backwash at
regular intervals will keep the filter mineral bed clean
and operating at top efficiency. Eventually, a neutral-
izer filter will require a refill of mineral because it does
dissolve away (see below). The activated carbon in a
taste & odor filter will need to be replaced after it has
exhausted its ability to adsorb (see next page).
