HOW YOUR WATER SOFTENER WORKS

B. SOFT WATER SERVICE and REGENERATION

[] FAST RINSE: Backwash is followed by a fast

flow of water down through the resin tank. The fast

flow packs the resin bed and gets it ready for return to service (FIG. 9).

After fast rinse, the softener returns to service. Hard water goes into the resin tank where the resin bed

again takes out the	hardness		minerals.	Soft water
goes to the house soft water pipes.

AUTOMATIC BYPASS

During the brining, brine rinse and backwash cycles

of regeneration, HARD water goes through the soft- ener valve and to the house pipes. If a faucet is opened, hard water is there for your needs. Howev-

er, you should not use hot water, if possible, because the water heater will refill with hard water. The soft-

ener, as factory programmed, regenerates from 2:00 AM to about 4:30 AM, a time when not much water is used.

If you get up early in the morning and you can hear

the softener regenerating, change the recharge start-

ing time. Set the recharge time to 12:00 AM or 1:00

AM (page 1- 4). Then regeneration will start and end that much earlier and your water heater will not re- fill with hard water if a hot faucet is opened.

ELECTRONICS

Two main parts of the softener's electronics are a WATER METER, and _ a COMPUTER.

WATER METER-- The water meter is in the soft-

ener valve outlet. As water flows through the meter,

it sends electric pulses to the computer. The com-

puter changes the pulses to a measure in gallons of water.

COMPUTER --The computer is part of the face-

plate timer circuit board. It is programmed to know

the softener's capacity (how many grains of hard- ness minerals it will take out of the water before a re-

generation is needed). When starting the softener,

page 1-4, you set it for the grains per gallon (gpg)

hardness		of the		water.
To find		a regeneration			pattern	best	for	your	needs,
the	computer		uses: (1) water usage from the meter,
(2)	hardness		setting,		(3) softener		capacity,		and	(4)
time	since		the	last	regeneration.	The		computer		al-

ways adjusts this pattern to your water using hab-

its. It works toward providing you with soft water

for the longest time and at the most efficient salt

usage.

Softening capacity is used as hard water goes

through the softener and hardness minerals are re-

moved.		When	the	computer	determines		that	only
enough		capacity	remains to provide			soft water up to
the	next	regeneration		starting	time	(2:00	AM,	or as
otherwise		set) it will		schedule	a regeneration.		When
the	regeneration			begins,	*RECHARGE		or	RE-
CHARGE		TIME	REMAINING		flashes during			the 2
hour	regeneration.
* Note:

If the CLEAN feature is set to ON, a cleaning back- wash (CLEAN and Blczvsh or Rinse flashes in the dis-

play, along with the minutes of the clean cycle re-

maining), precedes the recharge.
