INSTALLATION
Water Pressure
A minimum of 20 pounds (1.4 bar) of water pressure is
required for regeneration valve to operate effectively.
Electrical Facilities
An uninterrupted alternating current (A/C) supply is required.
NOTE: Note: sure your voltage supply is compatible with
your unit before installation.
Existing Plumbing
Condition of existing plumbing should be free from lime and
iron buildup. Piping that is built up heavily with lime and/
or iron should be replaced. If piping is clogged with iron,
a separate iron filter unit should be installed ahead of the
water softener.
Location Of Softener And Drain
The softener should be located close to a drain to prevent air
breaks and back flow.
Bypass Valves
Always provide for the installation of a bypass valve if unit is
not equipped with one.
CAUTION
Water pressure is not to exceed 125 psi (8.6 bar),
water temperature is not to exceed 110°F (43°C),
and the unit cannot be subjected to
freezing conditions.
Installation Instructions
1. Place the softener tank where you want to install the unit
making sure the unit is level and on a firm base.
2. During cold weather, the installer should warm the valve
to room temperature before operating.
3. All plumbing should be done in accordance with local
plumbing codes. The pipe size for residential drain line
should be a minimum of 1/2 inch (13 mm). Backwash flow
rates in excess of 7 gpm (26.5 Lpm) or length in excess
of 20 feet (6 m) require 3/4 inch (19 mm) drain line.
Commercial drain lines should be the same size as the
drain line flow control.
4. Refer to the dimensional drawing for cutting height of the
distributor tube. If there is no dimensional drawing, cut
the distributor tube flush with the top of the tank.
5. Lubricate the distributor o-ring seal and tank o-ring seal.
Place the main control valve on tank.
NOTE: Only use silicone lubricant.
6.
IMPORTANT:
For valves equipped with
electromechanical timers and stainless steel meters,
refer to the Meter Dome and Union Orientation section.
7. Solder joints near the drain must be done prior to
connecting the Drain Line Flow Control fitting (DLFC).
Leave at least 6 inches (15 cm) between the DLFC and
solder joints when soldering pipes that are connected on
the DLFC. Failure to do this could cause interior damage
to the DLFC.
8. Plumber tape is the only sealant to be used on the drain
fitting. The drain from twin tank units may be run through
a common line.
9. Make sure that the floor is clean beneath the salt storage
tank and that it is level.
10. Place approximately 1 inch (25 mm) of water above the grid
plate. If a grid is not utilized, fill to the top of the air check
(Figure 1) in the salt tank. Do not add salt to the brine tank
at this time.
11. On units with a bypass, place in bypass position. Turn on the
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. Once clean, close the water tap.
12. Slowly place the bypass in service position and let water
flow into the mineral tank. When water flow stops, slowly
open a cold water tap nearby and let run until the air is
purged from the unit.
13. Plug unit into an electrical outlet.
NOTE: All electrical connections must be connected according
to local codes. Be certain the outlet is uninterrupted.

STARTUP INSTRUCTIONS
The water softener should be installed with the inlet, outlet, and
drain connections made in accordance with the manufacturer’s
recommendations, and to meet applicable plumbing codes.
1. Turn the manual regeneraton knob slowly in a clockwise
direction until the program micro switch lifts on top of the
first set of pins. Allow the drive motor to move the piston to
the first regeneration step and stop. Each time the program
switch position changes, the valve will advance to the next
regeneration step. Always allow the motor to stop before
moving to the next set of pins or spaces.
NOTE: For electronic valves, please refer to the manual
regeneration part of the timer operation section. If the
valve came with a separate electronic timer service
manual, refer to the timer operation section of the
electronic timer service manual.
2. Position the valve to backwash. Ensure the drain line flow
remains steady for 10 minutes or until the water runs clear
(see above).
3. Position the valve to the brine / slow rinse position. Ensure
the unit is drawing water from the brine tank (this step may
need to be repeated).
4. Position the valve to the rapid rinse position. Check the drain
line flow, and run for 5 minutes or until the water runs clear.
5. Position the valve to the start of the brine tank fill cycle.
Ensure water goes into the brine tank at the desired rate.
The brine valve drive cam will hold the valve in this position
to fill the brine tank for the first regeneration.
6. Replace control box cover.
7. Put salt in the brine tank.
NOTE: Do not use granulated or rock salt.
3200 TIMER SETTING PROCEDURE
How To Set Days On Which Water Conditioner Is To Regenerate
(Figure 5)
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 fingers. Each
tab is one day. Finger at red pointer is tonight. Moving clockwise
from the red pointer, extend or retract fingers to obtain the
desired regeneration schedule.
How To Set The Time Of Day
1. Press and hold the red button in to disengage the
drive gear.
2. Turn the large gear until the actual time of day is at the time
of day pointer.
3. Release the red button to again engage the drive gear.
How To Manually Regenerate Your Water Conditioner At
Any Time
1. Turn the manual regeneration knob clockwise.
2. This slight movement of the manual regeneration knob
engages the program wheel and starts the
regeneration program.
3. The black center knob will make one revolution in the
following approximately three hours and stop in the position
shown in the drawing.
4. 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 one half of this time.
INSTALLATION CONTINUED
Meter Dome and Union Orientation
Control valves outfitted with an electromechanical timer and
stainless steel water meter include a special male x female
threaded stainless steel union to insure proper installation
and operation of the water meter.
The location of this union in relation to the
control valve and water meter is critical for
proper operation. DO NOT omit or substitute
this special union; it positions the meter
dome at the correct distance from the control
valve and allows re-positioning the water
meter dome for proper operation.
1. Apply a suitable thread sealant to the male threads of the
union and meter body.
2. Thread the union into the OUTLET port of the control
valve, then thread the meter into the union. See
illustrations below.
3. Rotate the water meter body so the meter dome is at
the 12 o’clock position. Loosen the nut on the union to
facilitate this if required. Once in position, tighten the
union nut.
4. Connect the meter cable to the open port in the center of
the meter dome.
5. Continue with the installation of the control valve.

CYCLE SETTING PROCEDURE
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.
3200 Series Timers (Figure 7)
1. To expose cycle program wheel, grasp timer in upper
left-hand corner and pull, releasing snap retainer and
swinging timer to the right.
2. To change the regeneration cycle program, the program
wheel must be removed. Grasp program wheel and
squeeze protruding lugs toward center, lift program wheel
off timer. Switch arms may require movement to
facilitate removal.
3. Return timer to closed position engaging snap retainer in
back plate. Make certain all electrical wires locate above
snap retainer post.
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
1. 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).
2. 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
1. 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).
2. To change the length of rapid rinse 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 Refill Time
1. The second group of holes in the program wheel determines
the length of time that your water conditioner will refill the
brine tank (2 min. per hole).
2. To change the length of refill time, move the two pins at the
end of the second group of holes as required.
3. The regeneration cycle is complete when the outer
microswitch is tripped by the two pin set at end of the brine
tank refill section.
4. The program wheel, however, will continue to rotate until
the inner micro switch drops into the notch on the
program wheel.
