Step 7

Install overfl ow line to brine tank overfl ow fi tting (Figure 3).  Discharge of line must be lower than overfl ow 
fi tting.  Do not interconnect overfl ow line with valve drain line (Step 6). 

Step 8

On time clock initiated models, set regeneration frequency.  Refer to regeneration frequency schedules (Sec-
tion 3)  to determine correct frequency, then refer to HOW TO SET TIME CLOCK REGENERATION CONTROL 
(Section 3) for instructions on setting frequency.  For meter initiated models, refer to HOW TO SET METER 
REGENERATION CONTROL. 

NOTE:  Regeneration settings for both time clock and meter initiated models are factory preset for the most 
effi cient salt use and minimum water consumption used for regeneration (as little as 50 gallons/89 liters), 
and conform to the industry salt effi ciency standards (required by some states).  Regeneration frequency 
schedules are designed for use with factory regeneration settings (listed in SPECIFICATIONS AND OPERATING 
DATA, Section 5). 

The control valve design permits adjustment of the salt dosage.  This adjustment may be necessary when 
unusual operating conditions exist, such as high concentrations of iron or hardness and/or high fl ow rates 
or daily water consumption.  This adjustment is easily performed by loosening the screw holding the white cam (on backside of timer) and adjusting the pointer 
to the desired pounds of salt. 

NOTE: For salt dosages greater than 15 lbs., grid leg extensions must be attached to bottom of grid legs. 

Step 9

Open main shut off valve to water system or turn on the well pump if on private water well and allow the water line to pressurize to check for leaks, correct if necessary. 

Step 10

Set time of day (refer to either Time Clock or Meter instructions on how to set backwashing control in Section 3).  When shifting to daylight saving time (and back), 
you may wish to adjust time of day accordingly. 

NOTE: 

 Time of regeneration is preset for 2:00 a.m. because at this time water consumption is generally minimal (a built-in hard water 

bypass does, however, permit water to be drawn during regeneration).  Should your lifestyle require 

regular

 use of water during the 2:00 

to 3:00 a.m. regeneration period, or if other water treatment equipment is also set for 2:00 a.m. regeneration, the time of regeneration 
will need changing.  To change, adjust time of day on 24-HOUR GEAR ahead or behind actual time of day.  For example, if 1:00 a.m. 
regeneration is desired and actual time of day is 10:00 a.m., 

advance

 24-hour gear one hour to 11:00 a.m.; or, should 3:00 a.m. regen-

eration be desired, set gear back one hour to 9:00 a.m. 

Step 11

Manually stage the water softener into a backwash cycle by grasping the black bar on the timer assembly and turning the dial until 
the word "BACKWASH" appears in the window. Next, slowly open the inlet valve on the bypass valve and allow the water softener to  
pressurize to line water pressure and ensure the unit has no water leaks. This will prevent any air entrapment in the top of the water 
softener. Once water is fl owing steady to drain and without color and air manually stage the water softener into the service position.
