HOW TO SET METER GENERATION CONTROL:
TYPICAL RESIDENTIAL APPLICATION:
To program, just set the time, set the hardness and it automatically monitors system needs and regenerates only when necessary. To set time of day, press red
time set button and turn 24-hour gear until present time of day is opposite “time of day arrow.” Set program wheel by lifting the “people” dial and rotating it so
that the number of people in the household is aligned with the grains per gallon water hardness (adjusted hardness*) scale. Release the dial and check for fi rm
engagement at setting. (This method will provide reserve capacity of one day’s supply based on 75 gallons per person.)
OPTIONAL PROGRAMMING PROCEDURE:
Calculate the gallon capacity of the system, subtract the necessary one day’s reserve requirement and set the gallons available opposite the small white dot on
the program wheel gear. Note: drawing shows 850 gallon setting. The capacity (gallons) arrow denotes remaining gallons exclusive of fi xed reserve.
HOW TO SET THE TIME OF DAY:
1) Press and hold the red button in to disengage the drive gear.
2) Turn the large gear until the actual time of day is opposite the time of day pointer.
3) Release the red button to again engage the drive gear.
HOW TO MANUALLY REGENERATE YOUR WATER SOFTENER AT ANY TIME:
A slight, clockwise movement of the manual regeneration knob engages the program wheel and starts the regeneration process.
The black center knob will make one revolution in the following approximately three hours and stop in the position shown in the drawing.
Even though it takes three hours for this center knob to complete one revolution, the regeneration cycle of your unit might be set for only one-third of this time.
In any event, conditioned water may be drawn after rinse water stops fl owing from the water conditioner drain line.
NOTE: The backside of the timer is set the same as the standard time clock regenerated models.
* Adjusted hardness equals hardness in grains per gallon (gpg) plus 3 times the iron in parts per million (ppm).
