The Culligan Process - Culligan HE Owner's Manual

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.
Service: While the control valve is in the
1.
service cycle, hard water is directed down
through the column of Cullex
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 ...
Regeneration: While the control valve is in
2.
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 ...
Brine Refill: While the control valve is in the brine refill cycle, a predetermined amount of
3.
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.
B. The Mineral Tank
The Mineral Tank contains the Cullex resin column, Cullsan
Culligan Municipal also includes carbon media for chlorine taste & odor reduction). The number of gal-
lons of hard water that can be softened by the Cullex resin column before it needs regeneration is called
the "capacity" of the resin column, and depends upon the amount of hardness minerals in each gallon of
water (expressed as grains per gallon) and upon the amount of regenerant brine solution (expressed as
pounds of salt) passed through the resin column during regeneration.
Your Culligan service person, taking into account the hardness of your water and the amount of softened
water your household may reasonably expect to use each day, has carefully established how often the
softener will regenerate and how much salt will be used for each regeneration. This will ensure that all of
your soft water needs will be fulfilled without using an excessive amount of salt.
C. The Brine System
The Brine System consists of a salt storage container and hydraulic Dubl-Safe
tainer holds the salt that is used to make the regenerant brine solution. The hydraulic Dubl-Safe valve limits
the amount of water that is returned to the salt storage tank during the brine refill cycle.
Because a predetermined amount of salt is dissolved with each brine refill cycle, the salt must be periodi-
cally replenished in order to maintain efficient operation. Your Culligan service person will be able to tell
you about how often salt must be added to the salt storage container.
