SOUND “BEEPER”: A “beeper” sounds while pressing
keypads for timer set-up. One beep signals a change in
the face plate display. Repeated beeps means the timer
will not accept a change from the keypad you have
pressed, telling you t o use another keypad. For example,
in setting the hardness (step 2), t he beeper sounds re-
peatedly when the display reaches 1 using the DOWN
keypad, or the highest hardness setting using t he UP
keypad.
1. SET PRESENT TIME OF DAY:

2. SET WATER HARDNESS NUMBER:
Press the SELECT keypad once to display 25 (flash-

Set the grains per gallon hardness of
your water supply (determined by w a-
teranalysisorcallyourlocalwaterde-
partment).
NOTE: If your water supply contains iron, compensate
for it by adding to the water hardness number. For exam-
ple, assume your water is 15 gpg hard and contains 2
ppm iron. Add 5 to the hardness number for each 1 ppm
of iron. In this example, you would use 25 for your hard-
ness number.
15 gpg hardness
2 ppm iron x 5 = 10 +10
