How Your Water Softener Works
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.
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.
SOFT WATER SERVICE AND REGENERATION
AUTOMATIC BYPASS
During the brining, brine rinse and backwash cycles of
regeneration, HARD water goes through the softener
valve and to the house pipes. If a faucet is opened,
hard water is there for your needs. However, you should
not use hot water, if possible, because the water heater
will refill with hard water. The softener, as factory pro-
grammed, regenerates from 2:00 AM to about 4:20 AM,
a time when not much water is used.
If you start your day prior to 4 AM, you may need to
change the recharge starting time. Set the recharge
time to 12:00 AM or 1:00 AM. Then regeneration will
start and end that much earlier and your water heater
will not refill 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 softener
valve outlet. As water flows through the meter, it sends
electric pulses to the computer. The computer
changes the pulses to a measure in gallons of water.
• COMPUTER The computer is part of the faceplate
timer circuit board. It is programmed to know the soft-
ener’s capacity (how many grains of hardness miner-
als it will take out of the water before a regeneration is
needed). When starting the softener, 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
(4) time since the last regeneration.
The computer always adjusts this pattern to your water
using habits. 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 removed. When
the computer determines that only enough capacity
remains to provide soft water up to the next regenera-
tion starting time (2:00 AM, or as otherwise set) it will
schedule a regeneration. When the regeneration
begins, *RECHARGE or RECHARGE TIME REMAIN-
ING flashes during the regeneration.
* Note: If the CLEAN feature is set to ON, a cleaning
backwash (CLEAN and Bkwsh or Rinse flashes in
the display, along with the minutes of the clean
cycle remaining), precedes the recharge.
