Installation Instructions
1. Place the softener tank where you want to install the unit making sure the unit is level and on a rm base.
(Maximum 7 feet apart for twin units.)
2. All plumbing should be done in accordance with local plumbing codes. The pipe size for the drain line should be the same size as the
drain line ow control female connection. Water meters are to be installed on soft water outlets. Twin units with (1) one meter shall be
installed on common soft water outlets of units.
3. Solder joints near the drain must be done prior to connecting the Drain Line Flow Control tting. Leave at least 6" between the DLFC
and solder joints when soldering when the pipes are connected on the DLFC. Failure to do this could cause interior damage to the
DLFC.
4. Teon tape is the only sealant to be used on the drain tting. The drain from twin units may be run through a common line.
5. Make sure that the oor is clean beneath the salt storage tank and that it is level
6. Place approximately 1" of water above the grid plate (if used) in your salt tank. Salt may be place in the unit at this time.
7. On units with by-pass, place in by-pass position. Turn on main water supply. Open a cold soft water tap nearby and let run a few
minutes or until the system is free from foreign material (usually solder) that may have resulted from the installation.
8. Place the by-pass in service position.
9. Manually index the softener control into "service" position and let water ow into the mineral tank. When water ow stops, open a
cold water tap nearby and let run until air pressure is relieved.
10. Electrical: All electrical connections must be connected according to codes. Use electrical conduit if applicable. Remote meter system
wiring diagrams are on page 26.
11. Plug into power supply

Start-up Setting Procedures
How To Set Days On Which Water Conditioner Is To
Regenerate:
Rotate the skipper wheel until the number "1" is at the red pointer.
Set the days that regeneration is to occur by sliding tabs on the
skipper wheel outward to expose trip ngers.
Each tab is one day. Finger at red pointer is tonight.
Moving clockwise from the red pointer, extend or retract ngers to
obtain the desired regeneration schedule.
How To Set The Time Of Day:
Press and hold the blue button in to disengage the drive gear.
Turn the large gear until the actual time of day is at the time of day
pointer.
Release the blue button to again engage the drive gear.
How To Manually Regenerate Your Water Condi-
tioner At Any Time:
Turn the manual regeneration knob clockwise.
This slight movement of the manual regeneration knob engages
the program wheel and starts the regeneration program.
The black center knob will make one revolution in the following
approximately three hours and stop in the position shown in the
drawing.
Even though it takes three hours for this center knob to complete
one revolution, the regeneration cycle of your unit might be set
only one half of this time.
In any event, conditioned water may be drawn after rinse water
stops owing from the water conditioner drain line.
How To Adjust Regeneration Time:
1. Disconnect the power source.
2. Locate the three screws behind the manual regeneration knob
by pushing the blue button in and rotating the 24 hour dial
until each screw appears in the cut out portion of the manual
regeneration knob.
3. Loosen each screw slightly to release the pressure on the time
plate from the 24 hour gear.
4. Locate the regeneration time pointer on the inside of the 24
hour dial in the cut out.
5. Turn the plate so the desired regeneration time aligns next to
the raised arrow.
6. Push the blue button in and rotate the 24 hour dial. Tighten
each of the three screws.
7. Push the blue button and locate the pointer one more time to
ensure the desired regeneration time is correct.
8. Reset the time of day and restore power to the unit.

Start-up Setting Procedures
Typical Programming Procedure
Calculate the gallon capacity of the system, subtract the necessary reserve requirement and set the appropriate gallons available opposite
the small white dot on the program wheel. Note, drawing shows 10,000 gallon setting. The capacity (gallons) arrow denotes remaining
gallons exclusive of the calculated reserve.
Note: To set meter capacity at initial start-up, either:
1. Rotate the manual regeneration knob one full revolution.
or
2. Rotate the program wheel manual clockwise and align white dot with capacity arrow.
This procedure must be followed any time the program wheel setting is changed.
How To Set The Time Of Day:
Press and hold the white button in to disengage the drive gear.
Turn the large gear until the actual time of say is opposite of the time of day pointer.
Release the white button to again engage the drive gear.
How To Manually Regenerate Your Water Conditioner At Any Time:
Turn the manual regeneration knob clockwise one "click".
This slight movement of the manual regeneration knob engages the program wheel and starts the regeneration program.
The black center knob will make one revolution in the following approximately three hours and stop in the position shown in the drawing.
Even though it takes three hours for this center knob to complete one revolution, the regeneration cycle of your unit might be set for only
on half of this time.
In any event, conditioned water may be drawn after rinse water stops owing from the water conditioner drain line.
Immediate Regeneration Times:
These timers do not have a 24 hour gear. Setting the gallons on the program wheel and manual regeneration procedure are the same as
previous instructions.
NOTE:
To set meter capacity
rotate manual knob
1-360º revolution to
set the gallons.

Regeneration Cycle
Program Setting Procedures
How To Set The Regeneration Cycle Program:
The regeneration cycle program on your water conditioner has been factory preset, however, portions of the cycle or program may be
lengthened or shortened in time to suit local conditions.
Timer Setting Procedure:
How To Change The Length Of The Backwash Time:
The program wheel as shown in the drawing is in the service position. As you look at the numbered side of the program wheel, the group
of pins starting at zero determines the length of time your unit will backwash.
For example: If there are six pins in this section, the time of backwash will be 12 min. (2 min. per pin). To change the length of backwash
time, add or remove pins as required. The number of pins times two equals the backwash time in minutes.
How To Change The Length Of Brine And Rinse Time:
The group of holes between the last pin in the backwash section and the second group of pins determines the length of time that your
unit will brine and rinse (2 min. per hole).
To change the length of brine and rinse time, move the rapid rinse group of pins to give more or fewer holes in the brine and rinse section.
Number of holes times two equals brine and rinse time in minutes.
How To Change The Length Of Rapid Rinse:
The second group of pins on the program wheel determines the length of time that your water conditioner will rapid rinse (2 min. per pin)
To change the length of rapid time, add or remove pins at the higher numbered end of this section as required. The number of pins times
two equals the rapid rinse time in minutes.
How To Change The Length Of Brine Tank Rell Time:
The second group of holes in the program wheel determines the length of time that your water conditioner will rell the brine tank (2 min.
per hole).
To change the length of rell time, move the two pins at the end of the second group of holes as required.
The regeneration cycle is complete when the outer micro-switch is tripped by the two pin set at the end of the brine tank rell section.
The program wheel, however, will continue to rotate until the inner micro-switch drops into the notch on the program wheel.

Water Conditioner
Flow Diagrams
1) Service Position
Hard water enters unit at valve inlet and ows down
through the mineral to the bottom. Conditioned water
ows up through the distributor tube, around the piston
and out the outlet.
2) Backwash Position
Hard water enters unit at valve inlet and ows through
the service adapter piston for by-pass, and up through the
coupling to regenerate valve inlet. Flow continues through
the regeneration valve piston - down the distributor tube -
through the bottom distributor and up through the mineral
- around the piston and out the drain. If optional no hard
water by-pass piston is used, water ow to service outlet
is prevented by an extension on the service outlet until
the end of the rapid rinse cycle or brine tank rell cycle,
depending on option chosen.
