TURBINE
OPERATION:
If no
water
is flowing
through
the softener,
the turbine
indicator
displays
3 zeros.
When
water
is flowing,
a 000 to 140 count
repeats
for each gallon
of water passing
through
the
turbine.
To check
for positive
operation
of the tur-
bine
if zeros
are shown,
open
a nearby
soft water
faucet
and observe
the turbine
count.
If you don't
get a reading
in the display,
with faucet
open,
pull
the sensor
from
the valve
outlet
port.
Pass a small
magnet
back and forth
in front
of the
sensor.
You should
get a reading
in the display.
If
you get a reading,
unhook
the in and out plumbing
and check
the turbine
for binding.
