Operating instructions

12 CULLIGAN MEDALLIST SERIES
Settings
The mircoprocessor can be set in two distinct operation modes, Soft-Minder
®
meter or Timeclock. As shipped from
the factory, the control is set for 8" Timeclock operation.
SOFT-MINDER OPERATION
The Soft-Minder meter utilizes a turbine impeller to accurately monitor the customers water usage. After a predeter-
mined amount of water has passed through the system, the microprocessor will signal a regeneration. The "REG"
enunciator will light at this point. The unit will perform a standard regeneration cycle at the preset time, unless the
programming option "dip2" is changed from "DEL" to "Id". When programming option "dip2" is changed from
"DEL" to "Id", a regeneration will begin immediately.
The programming of the Soft-Minder provides several settable variables, the Time-of-Day, Time-of-Regeneration,
Salt Dosage, Backwash Time, Brine/Rinse Time, Gallons to Signal and Timeclock Backup, if active. Refer to the
programming section for further information on programming the microprocessor.
TIME CLOCK OPERATION
When the mircoprocessor is set-up as a time clock unit, the Culligan Medallist Series
™
control will regenerate at
fixed intervals. The regeneration interval can be set anywhere from 1 to 42 days.
The programming for the time clock models is limited to Time-of-Day, Time-of-Regeneration, Salt dosage, Backwash
Time, Brine/Rinse Time, and the Regeneration Interval. Refer to the programming section for further information on
programming the microprocessor.
CAPACITY AND SALT SETTINGS
As mentioned previously, the softener will regenerate once the amount of water equal to the treated water volume
set point has passed through the turbine for meter models or after a fixed time interval for timeclock models.
Regeneration is either delayed until the selected regeneration time or immediate depending on how the
microprocessor is programmed. Before completing the programming, the following information must be determined:
1. Compensated Water Hardness.
If your water supply contains iron, compensate for it by the following procedure:
1. Multiply the iron by 0.1 and add the result to the hardness.
Example: (3 ppm of iron x 0.1) + 25 gpg of hardness = 25.3 gpg of total hardness
2. Choose the % capacity you want and refer to the table below for the appropriate multiplier.
Example: 67% capacity gives a multiplier of 1.5.
TABLE 2
% Capacity 50% 67% 75%
Multiplier 2 1.5 1.33
3. Multiply the result from Step 1 by the multiplier chosen in Step 2. This is the compensated hardness.
Example: 25.3 gpg total hardness x 1.5 = 38 gpg compensated hardness.
4. Use the effective hardness for sizing and to determine salt dosage and regeneration frequency.
5. The forced regeneration feature should be used for Soft-Minder meter operation to ensure the resin bed
does not become iron fouled due to lack of water flow. See "Programming the Option Settings" for the
forced regeneration feature.
