SECTION 2
HOW YOUR
WATER
SOFTENER
WORKS
J
2B.
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
fbr your
needs. However,
you should not use HOT water, if
possible,
because
the water heater
will refill with
hard
water.
The softener
regenerates
from
2:00
AM to about 4:00 AM, (you can change
this time...
see page 7), 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 time
setting. Set the recharge time to 12:00 AM or 1:00
AM (page 7). 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 pml of the
circuit board.
It is programmed
to know
the
softener's capacity (how many grains of hardness
minerals it will take out of the water before a
regeneration
is needed).
When
starting
the
softener, page 7, 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 always adjusts this pattern to your water
using habits. It works to provide you with soft
water fbr the longest time, 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 regeneration
starting time
(2:00 AM, or as otherwise set), it will schedule a
regeneration.
RECI_IARGE TONIGI_ITdisplays until
the regeneration
begins. When the regeneration
begins, TONIGHT goes off and RECHARGE NOW
flashes during the 2 hour regeneration.
