SET WATER HARDNESS NUMBER
1. Press the
MODE/SET
button until the
arrow points to
HARDNESS
. A flashing 25
will appear in the display.
2. Press the UP
or DOWN
buttons to
set your water hardness number.
NOTE:
If your water supply contains iron,
compensate for it by adding to the water
hardness number. For example, assume
your water is 20 gpg hard and contains 2
ppm iron. Add 5 to the hardness number
for each 1 ppm or iron. In this example, you
would use 30 for your hardness number.
3.
When the display shows your water
hardness (in grains per gallon), press
MODE/SET
to accept.
You can get the grains per gallon (gpg)
hardness of your water supply from a
water analysis laboratory. If you are on
a municipal supply, call your local water
department. Or call Legend Technical
Services, an independent laboratory,
to request a water hardness test kit at
1.800.949.8220, Option 4. If your report
shows hardness in parts per million (ppm)
or milligrams per liter (mg/l), simply divide
by 17.1 to get the equivalent number of
grains per gallon.
SET RECHARGE (STARTING) TIME
1. Press the
MODE/SET
button until the
arrow points to
RECHARGE
.
NOTE:
A flashing 2:00 AM (factory default)
should show in the display. This is a good
time for recharge to start (takes about 2
hours) in most households because water

house faucets during recharge.
If no change is needed, go to step 3.
To
Change the recharge starting time, follow

2.
Press UP
or DOWN
button to set
the desired recharge start time. Be sure
to observe the AM or PM as you did when
setting the time of day.
