Culligan Automatic Water Conditioner - Manual (Page 8)

The Culligan Process
Your Culligan water conditioner consists of three basic components, (A) the Control Valve, (B) the
Mineral Tank, and (C) the Brine System.
A. 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 oper-
ating 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 stor-
age 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 . . .
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.
