Keep this manual with your water softener. If repairs are needed, the service technician must have
the information on the following 8 pages. For telephone assistance, call toll free, 1-800-426-9345.
ALWAYS MAKE THESE INITIAL CHECKS FIRST
Does the time display show the correct time of
day?
- - If display is blank, check power source to the
softener.
--If time is flashing, power was off for over 6
hours. The softener resumes normal operation
but regenerations occur at the wrong time.
- - If an error code (Example: Err3) shows in the
faceplate display, go to AUTOMATIC ELEC­
TRONIC DIAGNOSTICS, page 5-2.
Plumbing bypass valve(s) must be fully in ser­
vice position.
The inlet and outlet pipes must connect to the
softener inlet and outlet respectively.
Is the transformer plugged into a "live",
grounded wall outlet, and the power cable fas­
tened securely to the controller?

The valve drain hose must be free of kinks and
sharp bends, and not elevated over 8 ft. above the
floor.
Is there salt in the storage tank?
Is the brine tubing connected? Brine tubing con­
nects to nozzle venturi and brine valve assembly.
(See page 6-3)
Is the brine valve float set right? (See page 5-4).
Press the SELECT button two times to display
the hardness setting. Be sure it is the correct set­
ting for the household's water supply. (Make a
hardness test of the raw water and compare with
the hardness setting. Also test a soft water sam­
ple to verify if a problem exists.) Press the SE­
LECT button twice more to return to present time
in the display.
If you do not find the problem after making initial
checks, do the MANUAL INITIATED ELEC­
TRONIC DIAGNOSTICS, and the MANUAL AD­
VANCE REGENERATION CHECK.
