CW-840-PB CONTAMINANT REDUCTION SYSTEM
In well water applications it may be necessary to deploy the ONE cartridge tank with a contaminant reduction cartridge
after a qualifying backwashing filter. This is to protect the lifespan and capacity of the contaminant reduction cartridge.
NOTE: It is necessary that all treated water from the ONE cartridge tank flows through the meter of the
associated unit. This is to ensure proper recording of gallons used through the meter.
SERVICE ALARM
The service alarm on the qualifying softener or backwashing filter must set to 100,000 gallons. This indicates the life of
the cartridge. Once 100,000 gallons has been reached, the controller will display a "Call Dealer For Service" message on
the display of the controller along with an audible alarm on some models. After triggering, the audible alarm may be
turned off by pushing any button on the front of the controller. This will only disable the audible portion of the alarm.
The display will continue to display "service is required".
Call servicing dealer for cartridge replacement and to reset the service alarm.
