9. Intermittent or
irregular
regenerant draw.
a. Low water pressure.
b. Defective injector.
a. Set pump to maintain 20 psi at conditioner.
b. Replace injector. (Contact dealer.)
10. No conditioned
water after
regeneration.
a. No regenerant in regenerant
tank.
b. Injector plugged.
c. Air check valve closes
prematurely.
a. Add regenerant to regenerant tank.
b. Clean injector and screen.
c. Put control momentarily into brine/slow
rinse, C2. Replace or repair air check if
needed. (Contact dealer.)
11. Backwashes or
purges at
excessively low
or high rate.
a. Incorrect drain controller used.
b. Foreign matter affecting valve
operation.
a. Replace with correct size controller. (Contact
dealer.)
b. Remove drain controller and clean ball and
seat.
12. No water flow
display when
water is flowing
on 760 controller.
a. Bypass valve in bypass.
b. Meter probe disconnected or not
fully connected to meter
housing.
c. Restricted meter turbine rotation
due to foreign material in meter.
a. Shift bypass valve to not-in-bypass position.
b. Fully insert probe into meter housing.
c. Remove meter housing, free up turbine and
flush with clean water. Turbine should spin
freely. If not, replace meter. (Contact dealer.)
13. Run out of
conditioned
water between
regenerations.
a. Improper regeneration.
b. Incorrect regenerant setting.
c. Incorrect hardness or capacity
settings.
d. Water hardness has increased.
e. Restricted meter turbine rotation
due to foreign material in meter.
a. Repeat regeneration, making certain that
correct regenerant dosage is used.
b. Set P6 to proper level. See salt setting chart.
c. Set to correct values. See Programming
section.
d. Set hardness to new value. See
Programming section.
e. Remove meter housing, free up turbine and
flush with clean water. Turbine should spin
freely; if not, replace meter. (Contact dealer.)
14. Regenerant tank
overflow.
a. Regenerant valve disc 1 being
held open by foreign matter.
b. Valve disc 2 not closed during
regenerant draw causing brine
refill.
c. Air leak in regenerant line to air
check.
d. Improper drain control for
injector.
e. Drain control clogged with resin
or other debris.
a. Manually operate valve stem to flush away
obstruction.
b. Flush out foreign matter holding disc open
by manually operating valve stem.
c. Check all connections in regenerant line for
leaks. Refer to instructions.
d. Too small of a drain control with a larger
injector will reduce draw rates.
e. Clean drain control.
