Culligan Mark 100 Owner's Manual page 7

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 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
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 . . .
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 dissolved to provide the brine solution that will be needed for the next
regeneration cycle.
B. The exclusive Bonded Tripl-Hull
The Mineral Tank of Aqua-Sensor
The number of gallons 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 serviceperson, 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 consists of a salt storage container and hydraulic Dubl-Safe
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.
Since a predetermined amount of salt is dissolved with each brine refill cycle, the salt must be periodically replenished in order to
maintain efficient operation. Your Culligan serviceperson will be able to tell you about how often salt must be added to the salt storage
container.
