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. 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 lter 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 125 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 rm base.
(Maximum 4 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 connection. Water meters are to be installed on soft water
outlets. Twin units with 1 meter shall be installed on common soft water outlet 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 placed in the unit
at this time.
7. 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.
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, close inlet valve, place control in “backwash” position to relieve head of air, then gradually open
inlet valve to purge remaining air in tank. Return control to service position.
10. Electrical: All electrical connections must be connected according to codes. Use electrical conduit if
applicable. Plug into power supply.

3200 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 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:
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 only one half of this time.
5. 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 red 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 time plate so the desired regeneration time
aligns next to the raised arrow.
6. Push the red button in and rotate the 24 hour dial.
Tighten each of the three screws.
7. Push the red 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.

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.
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 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 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
microswitch is tripped by the two pin set at 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.
