Logix Series Controllers
See Determining If You Have a 740 or 760 Control on page 24 to identify your
controller.
740 Controller - Electronic time clock control capable of doing 7-day (day of
week) regeneration, or up to a 99 interval day regeneration. This control will
operate both in a conditioner (softener) or 3-cycle filter mode with the same
controller.
760 Controller - Electronic metered-demand (volumetric) controller which
regenerates based on the water usage of the installation site. A calendar
override is a standard feature on this controller.
The Logix Series will operate on both the 255 and Performa valve body
series.
QUICK START
Initial Power-up
Initial Power Up - (CAMSHAFT proceeds to HOME position)
• At initial power-up, the camshaft will need to rotate to the HOME
(in service) position.
• Camshaft may take 1-2 minutes to return to home position.
• Err 3 will be displayed until the camshaft returns to home.
• If more than 2 minutes elapses, verify that the motor is turning the
camshaft. If it is not turning, see the troubleshooting section.
NOTE: The Logix controller features a self-test sequence. At first power-up
of the control, you may see a number such as 1.00, 1.02,1.04, or 2.00,
displayed. This is an indication that the self-test is not completed. To
complete the test, verify that the turbine cable is connected. Blow into the
turbine port (valve outlet) to spin the turbine. The controller will verify that
the turbine works and the self test will finish. Proceed with the initial start up
procedure.

There are no user-serviceable parts in the AC adapter, motor, or controller. In
the event of a failure, these should be replaced.
• All electrical connections must be completed according to local codes.
• Use only the power AC adapter that is supplied.
• The power outlet must be grounded.
• To disconnect power, unplug the AC adapter from its power source.
• Do not use petroleum based lubricants such as vaseline, oils, or
hydrocarbon based lubricants. Use only 100% silicone lubricants.
• All plastic connections should be hand tightened. Teflon tape may be
used on connections that do not use an O-ring seal. Do not use pliers or
pipe wrenches.
• All plumbing must be completed according to local codes.
• Soldering near the drain line should be done before connecting the drain
line to the valve. Excessive heat will cause interior damage to the valve.
• Observe drain line requirements.
• Do not use lead-based solder for sweat solder connections.
• The drain line must be a minimum of 1/2-inch diameter. Use
3/4-inch pipe if the backwash flow rate is greater than 7 GPM
(26.5 Lpm) or the pipe length is greater than 20 feet (6 m).
• Do not support the weight of the system on the control valve fittings,
plumbing, or the bypass.
• It is not recommended to use sealants on the threads. Use Teflon* tape
on the threads of the 1-inch NPT elbow, the drain line connections, and
other NPT threads.

General
• Observe all warnings that appear in this manual.
• Keep the media tank in the upright position. Do not turn on side, upside
down, or drop. Turning the tank upside down will cause media to enter the
valve.
• Operating ambient temperature is between 34F (1C) and 120F (49C).
• Operating water temperature is between 34F (1F) and 100F (38C).
• Working water pressure range is 20 to 120 psi (1.38 to 8.27 bar). In
Canada the acceptable working water pressure range is 20 to 100 psi
(1.38 to 6.89 bar).
• Use only regenerant salts designed for water softening. Do not use ice
melting, block, or rock salts.
• Follow state and local codes for water testing. Do not use water that is
micro biologically unsafe or of unknown quality.
• When filling media tank, do not open water valve completely. Fill tank
slowly to prevent media from exiting the tank.
• When installing the water connection (bypass or manifold) connect to the
plumbing system first. Allow heated parts to cool and cemented parts to
set before installing any plastic parts. Do not get primer or solvent on
O-rings, nuts, or the valve.
System Regeneration Cycles (7-Cycle Operation)
1. Service (Downflow) — Cycle C0:
Untreated water is directed down through the resin bed and up through
the riser tube. The hardness ions attach themselves to the resin and are
removed from the water. The water is conditioned as it passes through
the resin bed.
2. Backwash (Upflow) — Cycles C1, C6:
The flow of water is reversed by the control valve and directed down the
riser tube and up through the resin bed. During the backwash cycle, the
bed is expanded and debris is flushed to the drain.
3. Brine/Slow Rinse (Downflow) — Cycles C2, C3:
The control directs water through the brine injector and brine is drawn
from the regenerant tank. The brine is then directed down through the
resin bed and up through the riser tube to the drain. The hardness ions
are displaced by sodium ions and are sent to the drain. The resin is
regenerated during the brine cycle. Brine draw is completed when the air
check closes.
4. Repressurize Cycle — (Hard Water Bypass Flapper Open), Cycle C4:
This cycle closes the flappers for a short time to allow the air and water to
hydraulically balance in the valve before continuing the regeneration.

riser tube to the drain. Any remaining brine residual is rinsed from the
resin bed.
6. Brine Refill — Cycle C8:
Brine refill occurs during a portion of the fast rinse cycle. Water is directed
to the regenerant tank at a controlled rate, to create brine for the next
regeneration.

Location Selection
Location of a water treatment system is important. The following conditions
are required:
• Level platform or floor
• Room to access equipment for maintenance and adding regenerant (salt)
to tank.
• Ambient temperatures over 34F (1C) and below 120F (49C).
• Water pressure below 120 psi (8.27 bar) and above 20 psi
(1.4 bar).
• In Canada the water pressure must be below 100 psi (6.89 bar).
Left Side
EQUIPMENT INSTALLATION 13
• Constant electrical supply to operate the controller.
• Total minimum pipe run to water heater of ten feet (three meters) to
prevent backup of hot water into system.
• Local drain for discharge as close as possible.
• Water line connections with shutoff or bypass valves.
• Must meet any local and state codes for site of installation.
• Valve is designed for minor plumbing misalignments. Do not support
weight of system on the plumbing.
• Be sure all soldered pipes are fully cooled before attaching plastic valve
to the plumbing.
Rev E
Outdoor Locations
When the water conditioning system is installed outdoors, several items must
be considered.
• Moisture — The valve and 700 controller are rated for NEMA 3 locations.
Falling water should not affect performance.
The system is not designed to withstand extreme humidity or water spray
from below. Examples are: constant heavy mist, near corrosive
environment, upwards spray from sprinkler.
• Direct Sunlight — The materials used will fade or discolor over time in
direct sunlight. The integrity of the materials will not degrade to cause
system failures.
If it is necessary to locate the conditioner in direct sunlight, a protective
outdoor cover (P/N 1267811) over the valve and controller is necessary.
• Temperature — Extreme hot or cold temperatures may cause damage to
the valve or controller.
Freezing temperatures will freeze the water in the valve. This will cause
physical damage to the internal parts as well as the plumbing.
High temperatures will affect the controller. The display may become
unreadable but the controller should continue to function. When the
temperature drops down into normal operating limits the display will return
to normal. A protective cover (P/N 1267811) should assist with high
temperature applications.
• Insects — The controller and valve have been designed to keep all but
the smallest insects out of the critical areas. Any holes in the top plate can
be covered with a metal foil duct work tape. The top cover should be
installed securely in place.
• Wind — The Logix cover is designed to withstand a 30 mph
(48 Kph) wind when properly installed on the valve.
Water Line Connection
A bypass valve system should be installed on all water conditioning systems.
Bypass valves isolate the conditioner from the water system and allow
unconditioned water to be used. Service or routine maintenance procedures
may also require that the system is bypassed. Figures 5, 6, and 7 show the
three common bypass methods.

Drain Line Connection
WARNING: The inlet water must be connected to the inlet port of the
valve. When replacing non-Pentair Water valves, the inlet and outlet may
be reversed. It is also possible for the plumbing to be installed in an
opposite order.
Do not solder pipes with lead-based solder.
WARNING: Do not use tools to tighten plastic fittings. Over time, stress
may break the connections. When the 1265 or 256 bypass valve is used,
only hand tighten the plastic nuts.
WARNING: Do not use petroleum grease on gaskets when connecting
bypass plumbing. Use only 100% silicone grease products when installing
any plastic valve. Non-silicone grease may cause plastic components to fail
over time.
NOTE: Standard commercial practices are expressed here. Local codes
may require changes to the following suggestions. Check with local
authorities before installing a system.
1. The unit should be above and not more than 20 feet (6.1 m) from the
drain. Use an appropriate adapter fitting to connect 1/2-inch (1.3 cm)
plastic tubing to the drain line connection of the control valve.
2. If the backwash flow rate exceeds 5 gpm (22.7 Lpm) or if the unit is
located 20-40 feet (6.1-12.2 m) from drain, use 3/4-inch (1.9 cm) tubing.
Use appropriate fittings to connect the 3/4-inch tubing to the
3/4-inch NPT drain connection on valve.
3. The drain line may be elevated up to 6 feet (1.8 m) providing the run does
not exceed 15 feet (4.6 m) and water pressure at the conditioner is not
less than 40 psi (2.76 bar). Elevation can increase by 2 feet (61 cm) for
each additional 10 psi (.69 bar) of water pressure at the drain connector.
4. Where the drain line is elevated but empties into a drain below the level of
the control valve, form a 7-inch (18-cm) loop at the far end of the line so
that the bottom of the loop is level with the drain line connection. This will
provide an adequate siphon trap.
Where the drain empties into an overhead sewer line, a sink-type
trap must be used.
Secure the end of the drain line to prevent it from moving.

Drain Line Connection
NOTE: Waste connections or drain outlet shall be designed and
constructed to provide for connection to the sanitary waste system through
an air-gap of 2 pipe diameters or 1 inch (22 mm) whichever is larger.
WARNING: Never insert drain line directly into a drain, sewer line, or trap
(Figure 8). Always allow an air gap between the drain line and the
wastewater to prevent the possibility of sewage being back-siphoned into
the conditioner.
Overflow Line Connection
(not used with 3-cycle filter system)
In the event of a malfunction, the regenerant TANK OVERFLOW will direct
“overflow” to the drain instead of spilling on the floor. This fitting should be on
the side of the cabinet or regenerant tank. Most tank manufacturers include a
post for the tank overflow connector.
To connect the overflow line, locate hole on side of tank. Insert overflow fitting
into tank and tighten with plastic thumb nut and gasket as shown (Figure 9).
Attach length of 1/2-inch (1.3-cm) I.D. tubing (not supplied) to fitting and run to
drain. Do not elevate overflow line higher than overflow fitting.
Do not tie into drain line of control unit. Overflow line must be a direct,
separate line from overflow fitting to drain, sewer or tub. Allow an air gap as
per drain line instructions.

Regenerant Line Connection
(not used with 3-cycle filter system)
The regenerant line from the tank connects to the valve. Make the
connections and hand tighten. Be sure that the regenerant line is secure and
free from air leaks. Even a small leak may cause the regenerant line to drain
out, and the conditioner will not draw regenerant from the tank. This may also
introduce air into the valve causing problems with valve operation.
Most installations utilize a tank check valve. This is not necessary when using
the 255 valve with the built-in aircheck. Using a tank check valve with the 255
valve with aircheck will result in premature checking of the aircheck valve,
before the tank is empty.

(normal operation)
Make sure power source matches the rating printed on the AC adapter.
NOTE: The power source should be constant. Be certain the AC adapter is
not on a switched outlet. Power interruptions longer than 8 hours may
cause the controller to lose the time and day settings. When power is
restored, the day and time settings must then be re-entered.
The 700 Series controller is available in two power configurations. The North
American controller operates on 60 Hz. If the incoming power is 50 Hz, the
"North American" controller will not function. The error code
"ERR 2" will show on the display.
The "World" controller will sense the input power as 50 or 60 Hz and operate
accordingly.
Controller Location
The 700 Series controllers are designed to be mounted on the valve or
attached to a flat surface. Installations that do not provide easy access to the
valve can have the controller mounted for remote operation.
A remote mount connection, P/N 1256257, is available for the 700 Series
controller.
Valve Camshaft
The front end of the camshaft has an indicator cup. The cup has slots in the
outer periphery and numbers on the inside face (Figure 13).
The numbers can be seen with the cover off, from the front over the top of the
controller. The number at the top indicates which regeneration cycle is
currently in progress.

SYSTEM DISINFECTION
Disinfection Of Water Conditioners
The materials of construction of the modern water conditioner will not support
bacterial growth, nor will these materials contaminate a water supply. During
normal use, a conditioner may become fouled with organic matter, or in some
cases with bacteria from the water supply. This may result in an off-taste or
odor in the water.
Some conditioners may need to be disinfected after installation and some
conditioners will require periodic disinfection during their normal life.
Depending upon the conditions of use, the style of conditioner, the type of ion
exchanger, and the disinfectant available, a choice can be made among the
following methods.
Sodium or Calcium Hypochlorite
Application
These materials are satisfactory for use with polystyrene resins, synthetic gel
zeolite, greensand and bentonites.
5.25% Sodium Hypochlorite
These solutions are available under trade names such as Clorox*. If stronger
solutions are used, such as those sold for commercial laundries, adjust the
dosage accordingly.
1. Dosage
A. Polystyrene resin; 1.2 fluid ounce (35.5 ml) per cubic foot.
B. Non-resinous exchangers; 0.8 fluid ounce (23.7 ml) per cubic foot.
2. Brine tank conditioners
A. Backwash the conditioner and add the required amount of hypochlorite
solution to the well of the regenerant tank. The regenerant tank should
have water in it to permit the solution to be carried into the conditioner.
B. Proceed with the normal regeneration.
*Clorox is a trademark of the Clorox Company.
Calcium Hypochlorite
Calcium hypochlorite, 70% available chlorine, is available in several forms
including tablets and granules. These solid materials may be used directly
without dissolving before use.
1. Dosage
A. Two grains (approximately 0.1 ounce [3 ml]) per cubic foot.
2. Regenerant tank conditioners
A. Backwash the conditioner and add the required amount of hypochlorite
to the well of the regenerant tank. The regenerant tank should have
water in it to permit the chlorine solution to be carried into the
conditioner.
B. Proceed with the normal regeneration.

GENERAL 700 SERIES INSTRUCTIONS
700 SERIES CONTROLLER
Power Loss Memory Retention
The 700 Series controllers feature battery-free time and date retention during
the loss of power. This is designed to last a minimum of 8 hours depending on
the installation. The controller will continue to keep time and day in dynamic
memory while there is no AC power.
The controller will not track water usage on volumetric demand controls in the
event of a power failure.
All programmed parameters are stored in the 700 Series static memory and
will not be lost in the event of a power failure. These settings are maintained
separately from the time and day settings.
Motor
The 700 series controller uses a standard 12-volt AC motor that works with
either 50 Hz or 60 Hz. The same motor is used worldwide and does not need
to be changed for different power conditions.
Power
700 Series controllers are available in two power configurations:
1. The North American model requires 60 Hz input. The controller will dis-
play USA units when power is first applied.
2. The World model accepts either 60 or 50 Hz input and will automatically
adjust measurement units when power is first applied.
Information entered or calculated by the controller is stored in two different
ways.
A static memory will store:
Media volume
Regenerant setting
Time of regeneration
Days between regeneration
Filter mode
A dynamic memory with 8 hour retention will store:
Current day of week
Running clock
NOTE: Water flow to the valve can be turned on or bypassed when the
controller is powered up for the first time.
GENERAL 700 SERIES INSTRUCTIONS 25

Variable Reserve Function
The 700 Series metered-demand volumetric controllers (760 and 760C) are
designed to have a variable reserve feature. This feature automatically
adjusts the reserve to the end-user’s water usage schedule.
A variable reserve saves salt and water by only regenerating when absolutely
necessary, and ensures enough soft water for typical
high-water usage days.
Each day of regeneration the controller reviews the last four weeks of water
usage for the same day of the week to determine if the remaining capacity is
adequate for the next day of the week. If the remaining capacity is not
adequate, it will initiate an automatic regeneration.

Conditioner and FA Filter Start-Up
After you have performed the previous initial power-up steps, you will need to
place the conditioner into operation. Follow these steps carefully, as they
differ from previous valve instructions.
WARNING: Do not rotate the camshaft by hand or damage to the unit may
occur. Use the controller to step the camshaft electronically through the
cycles.
1. Remove the cover from the valve. Removing the cover will allow you to
see that the camshaft is turning, and in which cycle the camshaft is currently positioned.
2. With the supply water for the system still turned off, position the bypass
valve to the “not in bypass” (normal operation) position.
3. Hold the REGEN button on the controller down for 5 seconds. This will
initiate a manual regeneration.
The controller will indicate that the motor is turning the camshaft to
the cycle C1 (Backwash) position by flashing an hourglass. The
controller will display the total regen time remaining.
If you press and hold the SET button, the controller will indicate the
time remaining in the current cycle.
4. Fill the media tank with water.
A. While the controller is in cycle C1 (Backwash), open the water supply
valve very slowly to approximately the 1/4 open position.
WARNING: If opened too rapidly or too far, media may be lost out of the
tank into the valve or the plumbing. In the ¼ open position, you should hear
air slowly escaping from the valve drain line.
B. When all of the air has been purged from the media tank (water begins
to flow steadily from the drain line), open the main supply valve all of
the way. This will purge the final air from the tank.
C. Allow water to run to drain until the water runs clear from the drain line.
This purges any refuse from the media bed.
D. Turn off the water supply and let the system stand for about five
minutes. This will allow any air trapped to escape from the tank.
5. Add water to the regenerant tank (initial fill) (conditioner only).
A. With a bucket or hose, add approximately 4 gallons (15 liters) of water
34 PLACING CONDITIONER INTO OPERATION (turning on the water)

the water level is approximately 1 inch (25 mm) above the platform.
NOTE: We recommend that you do not put regenerant into the tank until
after the control valve has been put into operation. With no regenerant in
the tank, it is much easier to view water flow and motion in the tank.
6. Engage the refill cycle to prime the line between the regenerant tank and
the valve (conditioner only).
A. Slowly open the main water supply valve again, to the fully open
position. Be sure not to open too rapidly as that would push the media
out of the media tank.
B. Advance the controller to the Refill (C8) position. From cycle C1
(Backwash), press and hold the SET button. This will display the
current cycle.
While pressing the SET button, press UP to advance to the next cycle.
Continue to advance through each cycle until you have reached cycle
C8 (Refill).
NOTE: As you advance through each cycle there will be a slight delay
before you can advance to the next cycle. The hourglass icon will light while
the camshaft is indexing. There may be a pause at cycle C4 (System
Pause). This cycle allows the water/air pressure to equalize on each side of
the valve discs before moving on. The hourglass will not be visible
indicating that the system is paused.
C. With the water supply completely open, when you arrive at cycle C8
(Refill), the controller will direct water down through the line to the
regenerant tank. Let the water flow through the line until all air bubbles
have been purged from the line.
D. Do not let the water flow down the line to the tank for more than one to
two minutes, or the tank may overfill.
E. Once the air is purged from the line, press the SET button and the UP
button simultaneously to advance to cycle C0 (Treated Water) position.
7. Draw water from the regenerant tank.
A. From the treated water position (cycle C0), advance the valve to the
draw regenerant position. Hold the REGEN button down for five
seconds.
The controller will begin a manual regen, and advance the control valve
to the cycle C1 (Backwash). Press the SET and UP button to advance
to cycle C2 (Draw).
B. With the controller in this position, check to see that the water in the
regenerant tank is being drawn out of the tank. The water level in the
tank should recede very slowly.
C. Observe the water being drawn from the regenerant tank for at least
three minutes. If the water level does not recede, or goes up, check all
PLACING CONDITIONER INTO OPERATION (turning on the water) 35

8. If the water level is receding from the regenerant tank you can then
advance the controller back to the treated water (C0) position by pressing
SET and the UP buttons simultaneously to advance the controller to the
C0 position.
9. Finally, turn on a faucet plumbed after the water conditioner. Run the
faucet until the water runs clear. Add regenerant to the regenerant tank.
Things You Might Need to Know
• When the controller is first plugged in, it may display a flashing hourglass
and the message Err 3, this means that the controller is rotating to the
home position. If the Err 2 is displayed, check that the incoming power
frequency matches the controller. The North American controller will not
run with 50 Hz input.
• The preset default time of regeneration is 2:00 AM.
• English or Metric? The World controller senses the electrical input and
decides which is needed. The North American controller only runs on 60
Hz and defaults to English units.
• The 700 Series controller can be programmed to regenerate on specific
days of the week.
• If electrical power is not available, the camshaft can be rotated
counterclockwise by hand if the motor is removed.
• The 700 Series controllers send commands to the motor for camshaft
movement. However, water pressure/flow are required during the
regeneration cycle for backwash, purge and refill, and brine draw to
actually take place.
• Make sure control power source is plugged in. The transformer should be
connected to a non-switched power source.
• You can start programming at the beginning by resetting the amount of

to prevent overflow.
Initial Resin Volume Setting
Programming for a manganese greensand system requires a few minor
adjustments to the programming to operate the control correctly. The initial
resin volume should be set to the closest volume of the manganese
greensand in the system. For example, if the system contains two cubic feet
of manganese greensand, program in 2.00 for the resin volume.
"Salt" Setting for KMNO3 Regenerant
Since the same injector is used for the filter application (FA) system and the
conditioner system, be sure the regenerant (salt) setting is set to High “H” to
allow adequate time to rinse the media.
All other settings will remain the same as mentioned in the previous
programming sections.
Days Between Regeneration Setting (740 FA)
To set the days between regenerations, consult the media manufacturer for
the actual capacity of the media.
In general, manganese greensand has a capacity of 10,000 ppm of removal
capability per cubic foot of media. Calculate the capacity of the system by
taking the number of cubic feet of media and multiply by 10,000.
For example, using a 1 cubic foot system provides 10,000 ppm of removal
capability.
The next step is to calculate the demand for the system. Multiply the predicted
daily water usage by the iron content in ppm.
For example, an average person uses 75 gallons of water per day. Four
people living in a home use 300 gallons of water (75 gallons x 4 people) per
day. Assume the incoming water has 10 ppm of iron. Now calculate the daily

content (10) = 3000 ppm of daily capacity usage.
Now take the system capacity (10,000), divided by the daily demand (3,000) =
3.3 days of capacity. Since you will run out of capacity before the beginning of
the fourth day, the proper setting for days between regeneration is 3 days.
For example:
4 people x 75 gals per person = 300 gallons used per day.
10 ppm iron x 300 gal/day = 3000 ppm/day
10,000 ppm capacity 3000 ppm/day = 3.3 days of total capacity
Solution = regenerate every 3 days.
Volume/Demand Regeneration Setting
To set a 760 demand system for iron removal you must:
1. Know your media capacity. Generally, one cubic foot of magnesium
greensand can remove 10,000 ppm of iron.
2. Know the iron concentration in your water.
To have your system regenerate on demand, set your system’s capacity (P7)
to the appropriate factor. On the 760, it will read Kg, but you will actually be
working in ppm of iron.
KG
1. If your system is one cubic foot, set the capacity to "10" kg, meaning
10,000. For two cubic feet, set the capacity to "20" kg.
2. Set your hardness to the level of ppm iron in your water. If you have 3
ppm of iron, set the 760 control to "3".
3. The control will calculate the remaining volume capacity in gallons (m
and count down to regeneration.

Camshaft
Slots
Lobes
Cup
The camshaft has several lobes that push open the valve discs as the
camshaft rotates. Rotation is controlled by a drive motor that drives a gear at
the rear of the camshaft. The front end has a cup with markings and slots.
WARNING: The camshaft slots are molded to exact dimensions. Do not
attempt to modify the cam cup slots. Improper regen will occur!
The outside surface of the cup has an arrow mark. When the arrow is at top
center, the camshaft is in the loading position. 90 degrees clockwise on the
cup an optical sensor is mounted to the top plate. This sensor reads the slots
as they pass through. The largest slot is “Home” and the remaining slots are
positioned to signal the regeneration cycles.
When looking at the end of the camshaft, numbers are visible in the hollow of
the cup. An arrow on the top plate points to the current marking. The numbers
represent regeneration cycles as follows:
C0 =Treated water-normal operation mode
C1 = Backwash
C2 = Regenerant draw (not used in filter mode)
C3 = Slow rinse (not used in filter mode)
C4 = System pause
C5 = Fast rinse cycle 1
C6 = Backwash cycle 2 (not used in filter mode)
C7 = Fast rinse cycle 2 (not used in filter mode)
C8 = Regenerant refill (not used in filter mode)
These numbers are offset rotationally 90 degrees from the matching slot. The
offset enables the service person to view the number at the top of the cup and
determine which slot is at the optical sensor.
NOTE: If any part of the camshaft is broken or damaged the camshaft
should be replaced. Do not repair or modify damaged cam lobes, gears or
timing cup.
