Culligan Medallist 8" Installation manual

Use this sheet to assist in programming the Medallist water softener when used as a standard application. Please refer to the Medallist Installation and Operation Manual if
modifications need to be made to the programming options or service check out.
Make sure the inlet water supply is turned off, then supply power to the timer. The display will power up flashing "12:00 PM" and the motor will energize and cycle the control, without
stopping, to the home position. This is required to ensure that the control is in the home position.
The timer uses four buttons:
1. STATUS: Advance timer through display options.
2. UP ARROW "+": Increase the setting.
3. DOWN ARROW "-": Decrease the setting.
4. REGEN.: Initiate a manual regeneration.
SETTING THE MICROPROCESSOR
The microprocessor senses when it is installed as a Soft-Minder®control. Adding or
removing any connection to the board will automatically reset the microprocessor to the
factory settings.
Step 1 – Programming Time of Day
Press the “STATUS” key.
The display will blink “tod” for 3 seconds
and then change to time of day with the “ones” digit blinking.
Adjust the “ones” digit with the “+” or “-” keys.
Press the “REG” key to blink the “tens” digit.
Adjust the “tens” digit with the “+” or “-” keys.
Press the “REG” key to blink the “hours” digit.
Adjust the “hours” digit with the “+” or “-” keys.
Press the “REG” key to cycle back to “ones” or
Note: The “hours” setting scrolls through 1-12 AM and 1-12 PM. Make sure the
proper AM or PM indicator is shown when setting the time.
Step 2 – Programming Regeneration Time
Press the “Status” key after setting the time of day.
The display will blink “tor” for 3 seconds and then
change to the time setting with the “ones” digit
blinking. Adjust regeneration time as time of day
above.
Note: This option will not show if the “dIP 2” option is set to immediate
Step 3 – Programming Salt Dosage
Press the “Status” key after programming
regeneration time.
The display will blink “SLtP” if set to English or
“SLtG” if set to Metric for 3 seconds and then
display the salt dosage. Refer to the reverse side of this sheet for salt settings.
Adjust the setting with the “+” or “-” key (3-24 lbs.)(1-10 kgs.)
Note: This option will not show if the control is set to Filter mode.
Step 4 – Programming Backwash Time
Press the “Status” key after programming salt
dosage.
The display will blink “bw” for 3 seconds and then
display the backwash time in minutes.
Adjust the setting with “+” or “-” key. (1-40 minutes)
Step 5 – Programming Brine Draw/Slow Rinse
Time
Press the “Status” key after programming the
backwash time.
The display will blink “br” for 3 seconds and then
display the brine draw/slow rinse time in minutes.
Adjust the setting with the “+” or “-” key. (35-99 minutes). See Table 5 for
suggested brine draw/slow rinse times.
Note: This option will not show if the control is set to Filter mode.
Step 6 – Programming Gallons (Liters) or Days to
Regeneration
Meter Mode —
Press the “Status” key after programming the brine
draw/slow rinse time.
The display will blink “CAPG” (“CAPL”) for 3 seconds and then display the
gallons or liters set point.
Adjust the setting with the “+” or “-” key. (10-9990 Gallons)
(40-37000 Liters). Refer to the reverse side of this sheet for calculating capacity
setting.
Note: The programmed value must be multiplied by 10 to obtain the actual setting.
For example, if 87 is shown in the display, the control will regenerate after 870
gallons have passed through the meter.
Timeclock Mode —
Press the “Status” key after programming the brine draw/slow rinse time.
The display will blink “CAP” for 3 seconds and then display the number of days
between regenerations.
Adjust the setting with the “+” or “-” key. (1-42 days). Refer to the reverse side of
this sheet for calculating time clock settings.
Exiting Program Mode
From Step 6 (or step 7 if it is active) press the “Status” key.
The display will go blank.
Press the “Status” key again to exit programming.
Note: The control will exit the programming mode if no key press activity takes
place within one minute.
Locking the Programmed Menu
Press and hold the “+” key for 3 seconds while in the service mode.
The display will show the status of the lock feature. (“LoC” or “unL”)
Adjust with the “+” or “-“ key.
Press the “STATUS” key to return to the service mode.
Note: While the programmed menu is locked (“LoC”) all of the programming
menu items will display, however only the time of day can be changed.
Note: If programming times out, values will not be saved. The “Status” key must be
pressed to save values.

MEDALLIST PROGRAMMING INSTRUCTIONS

Softener Capacity
Compensated Hardness
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.
2. Salt Dosage
From Table 3, select the salt dosage at which the softener will be operated.
• Low Setting — Maximum salt efficiency, more frequent regeneration, reduced
overall softening capacity.
• Medium Setting — Good combination of efficiency and overall softening capacity.
• High Setting — Maximum softening capacity, less frequent regeneration, and
reduced salt efficiency.
Recommended whenever iron is present and for hardness levels above 30 Grains
Per Gallon, or high volume water usage.

3. Treated Water Volume Set Point
Calculate the treated water volume set point using the following information:
• Softening capacity — Grains (based upon salt dosage setting).
• Compensated hardness of water supply — Grains Per Gallon
• Estimated daily water usage — Gallons Per Day (refer to Table 4)

Example - Meter: Softener Model Medallist 2M

Estimated Daily Water Usage: 300 Gallons Per Day
Treated Water Volume Set Point = — Water Usage
Softening Capacity 25,100 Grains
Divide by Compensated Hardness ÷ 19 Grains per Gallon
Result is total number of gallons 1,321 Gallons
of soft water per regeneration
Subtract daily Water Usage (needed — 300 Daily Water Usage (One Day Supply)
as a reserve to ensure continuous 1,021 Gallons
soft water until regeneration occurs).

BRINE VALVE "A" DIMENSION
The brine valve contains a float-actuated safety shut-off
device to prevent overflow of the brine tank in the unlikely
case of an electrical or mechanical failure during the brine tank
refill cycle.
It is recommended that the brine valve float be used as in-
tended, that is, as a secondary, safety shut-off. Remember, the
timer mechanism provides the primary refill shut-off. To use
the float as a safety shut-off, refer to Table 4 for the salt dosage
and brine tank size being used. The "A" dimension is the
distance between the filter screen and the bottom of the float
(Figure 11) when the float stem is in its fully raised position;
adjust the float and rubber grommets accordingly.
