on pressures above the UPC for extended periods of time can increase the service frequency and failure of replacement
parts� On a private water system, make sure the minimum pressure (when the pump starts) is greater than 20 psi (140 kPa)�
CAUTION!
The use of a pressure reducing valve may limit the flow of water in the household.
Temperature
- Do not install the unit where it might freeze, or next to a water heater or furnace or in direct sunlight�
Outdoor installations require the use of the Outdoor Iron-OX5 filter system� Indoor systems installed outdoors will void the
warranty and UL certification�
Reconditioning Cycle
There are several conditions that will cause the control to initiate a reconditioning cycle� The “REG” enunciator will
light when the control has signaled for a reconditioning cycle� The “REG” enunciator will flash while the control is in a
reconditioning cycle� The following are conditions that will call for reconditioning, assuming “dip 2” has been set to “DEL”:
1� When the time clock has counted past the set number of days�
2� At the preset time, after the “REG” button is depressed once� “REG” will light�
3� Immediately, when the “REG” button is depressed for three seconds� “REG” will light and blink�
4� Immediately, if power to the unit has been off for more than 3 hours and time of day has been returned�
5� When the flow meter has recorded the passage of a predetermined number of gallons�
If “Dip Switch 2” is set to “Immediate”, the unit will begin a reconditioning cycle immediately for instances 2 and 4� With
“Dip Switch 2” set to “Delayed”, the reconditioning cycle will not begin until the preset reconditioning time�
NOTE!
If set to immediate mode as timeclock, the unit will initiate the reconditioning cycle at 12:00 AM. In the
delay mode, “REG” indicator will light at 12:00 AM and reconditioning cycle will occur at programmed
delayed time.
Display Lockout
The Culligan Select Plus
®
Series control is equipped with a feature which will allow you to protect the programmed
settings from tampering by unauthorized individuals� When the lockout feature is activated, the only parameters which can
be adjusted are the Time-of-Day and the Time of Reconditioning Cycle� Refer to the “Setting of the Microprocessor” for
activating this feature�
Power Loss
The AccuSoft
®
circuit board is equipped with a Hi-Cap Capacitor and EEPROM memory chip� The capacitor is capable
of maintaining the time, for at least two days, in the event of a power outage� The EEPROM ensures that the individual
programming parameters of the filter are retained�
If the power outage lasts long enough to drain the Hi-Cap Capacitor, the control will flash “12:00 PM” when power
is returned to the control� The unit will continue to keep time from the moment power is restored, and will initiate a
full reconditioning cycle at the preset reconditioning time� The time of day will need to be reset in order to return the
reconditioning cycle to its preset time�
Installing the optional battery back-up onto the circuit board will ensure the correct time of day is retained in the event of
power outages lasting longer than two days�
Service
The Culligan Select Plus
®
water filter is equipped with a self diagnostic program to insure optimal operation of your water
filter� Should service become necessary, a phone icon will appear in the display� If this condition occurs, call your local
Culligan Dealer for assistance� The phone icon and error code will be the only items displayed when service is required on
the control�
