hardness number in the display. DOWN ▼decreases the hardness value. UP

NOTE
: Each press of a button changes the display by 1, between 1 and 25.
Above 25, the display changes 5 at a time (25, 30, 35, etc.). Holding a
button in changes the numbers at a rapid rate.
3. When the display shows your water hardness (in grains per gallon), press
SELECT to accept.
NOTE: If there is clear water iron in your water supply, you will need to
increase the hardness setting by 5 for each 1 ppm of clear water iron in your
water supply. 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 your local dealer to request a water hardness
test kit.
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. To
convert to other hardness indications use the following conversion: 1gpg = 0.959
°dH = 1.71 °fH = 171 ppm.
SET RECHARGE (STARTING) TIME
1. Press the SELECT button a flashing 2:00 AM and the words “RECHARGE
TIME” show in the display.
NOTE: The 2:00 AM (factory default) is a good time for
recharge to start (takes about 2 hours) in most
households because water is not in use.
HARD WATER is bypassed to house faucets during
recharge. If no change is needed, go to step 3.
To change the recharge starting time, follow step 2.
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.
NOTE: Each press of a button changes the time by 1 hour. Holding the buttons
in changes the time at a rapid rate.
3. Press the SELECT button to accept.

SET MAX DAYS BETWEEN RECHARGES
The default setting allows the timer to control regeneration frequency based on water
usage readings from the water meter. It provides the most economical operation. You
can set a maximum time (in days) between regenerations. For example, no more than 3
days will pass without a regeneration occurring if you set “3 day" in the display. The
available settings are 1 to 15 days.
1. Press and hold the SELECT button until the display
