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.
