Your Culligan water conditioner consists of three basic components, (A) the Control Valve, (B) the Mineral
Tank, and (C) the Brine System.
A. Control Valve
The exclusive Culligan control valve automatically
performs a variety of tasks that are necessary for the
proper operation of your water conditioner. These tasks,
commonly referred to as cycles or operating positions,
are Service, Regeneration, and Brine Refill.
1. Service: While the control valve is in the
service cycle, hard water is directed down
through the column of Cullex® resin where
hardness minerals are removed from the
water. The softened water is then directed into
your household plumbing lines. The ability of
the Cullex resin to remove hardness minerals
needs to be periodically replenished; this is
referred to as ...
2. Regeneration: While the control valve is in
the regeneration cycle, water is first directed
up through the column of Cullex resin to flush accumulated sediment out of the resin and down
the drain. Then, the regenerant brine solution is slowly drawn from the bottom of the salt storage
tank of the Brine System and is directed down through the column of Cullex resin, restoring the
ability of the resin to remove hardness minerals from your water supply. Once completed, the
regeneration cycle is followed by ...
Mineral Reactivator: The Mineral Reactivator is educted for a specified duration during the
Brine Draw cycle. The Mineral Reactivator is designed to clean the Cullex resin pores of iron,
maganese, and organic compounds that cause resin fouling and inefficiencies.
NOTE Contact your Culligan dealer when you need to replenish the Mineral Reactivator.
Chlorine Generator: Chlorine is generated from the brine solution and then is added after
the eduction of the Mineral Reactivator. The chlorine inactivates trace amounts of iron-reducing
bacteria and sulfur-reducing bacteria.
3. Brine Refill: While the control valve is in the brine refill cycle, a predetermined amount of
water is directed to the salt storage tank of the Brine System so that additional salt can be dis-
solved to provide the brine solution that will be needed for the next regeneration cycle.
