General Commercial Pre-Installation Check List
WATER PRESSURE: A minimum of 25 pounds of water pressure is required for regeneration valve to operate
effectively.
ELECTRICAL FACILITIES: A continuous 115 volt, 60 Hertz current supply is required. (Other voltages available.)
Make certain the current supply is always hot and cannot be turned off with another switch.
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.
BY-PASS VALVES: Always provide for the installation of a by-pass valve.
CAUTION: Water pressure is not to exceed 120 p.s.i., water temperature is not to exceed 110° F, 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.
(Maximum 7 feet apart for twin units.) To provide for expansion and contraction of plastic resin tanks and rigid
plumbing loads, use FLEXIBLE FITTINGS at the valve.
2. Allplumbing should bedone in accordance with local plumbing codes. The pipe sizeforthe drain line should be the
same size as the drain line flow control connection. Water meters are to be installed on soft water outlets. Twin
units with (1) one meter shall be installed on common soft water outlet of units.
3. Make sure that the floor is clean beneath the salt storage tank and that it is level.
4. Place approximately 1″ of water above the grid plate (if used) in your salt tank. Salt may be placed in the unitat this
time.
5. Place in by-pass 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.
6. Place the by-pass in service position.
7. Manually index the softener control into “service” position and let water flow into the mineral tank. When water flow
stops, close inlet valve, place control in “backwash” position to relieve head of air, then graduallyopen inlet valve to
purge remaining air in tank. Return control to “service” position.
8. Electrical: All electrical connections must be connected according to codes. Use electrical conduit if applicable.
Plug into power supply.

inlet. Flow continues thru the regeneration valve piston down
the distributor tube thru the bottom distributor and up thru the
mineral around the piston and out the drain. If optional no
hard water by-pass piston is used, water flow to service outlet is
prevented by an extension on the service outlet until the end of
the rapid rinse cycle or brine tank refill cycle, depending on
options chosen.

brine valve to refill the brine tank. Inlet flow also continues down thru
mineral to the bottom distributor. Conditioned water flows up thru the
distributor tube, around the piston and out the outlet. Note: An option
is available to keep service valve in by-pass position until the end of
brine tank refill cycle.

Timer Setting Procedure
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 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:
Press and hold the red 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 red button to again engage the drive gear.
How To Manually Regenerate Your Water
Conditioner 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 thought it takes three hours for this center knob to

How To Set 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 & 3210 Series Timers (Figure to Right)
To expose cycle program wheel, grasp timer in upper lefthand corner and pull, releasing snap retainer and
swinging timer to the right
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.)
Return timer to closed position engaging snap retainer in
back plate. Make certain all electrical wires locate above

Timer Setting Procedure for 3200 & 3210 Timer
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 equal 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 unitwill 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 inthe
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 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 TankRefill Time:
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).
To change the length of refill time, move the two pins at
the end of the second group of holes as required.
The regeneration cycle is complete when the outer
microswitch is tripped by the two pin set at end of the
brine tank refill section. The program wheel, however, will
continue to rotate until the inner microswitch drops into
the notch on the program wheel.

Typical Programming Procedure
Calculate the gallon capacity of the system, subtract the
necessary reserve requirement and set the gallons
required by lifting the gallon dial and rotating it so that the
number of gallons required is aligned with the white dot
on program wheel gear. Release and check for firm
engagement with gear. Note, drawing shows 8,750 gallon
setting. The capacity (gallons) arrow denotes remaining
gallons exclusive of fixed reserve.
Note:
To set meter capacity at initial start-up, either:
1. Rotate manual regeneration knob one full revolution.
— or —
2. Rotate program wheel manually clockwise or counter
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 red button in to disengage the 24 hour
gear.
Immediate Regeneration Timers:
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.

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 one half of this time.
In any event, conditioned water may be drawn after rinse
water stops flowing from the water conditioner drain line.
