MANUAL OVERVIEW
How To Use This Manual
This installation manual is designed to guide the installer
through the process of installing and starting conditioners
featuring the 700 Logix series controllers.
This manual is a reference and will not include every system
installation situation. The person installing this equipment
should have:
• Training in the 700 Logix series controllers and water
conditioner installation.
• Knowledge of water conditioning and how to determine
proper control settings.
• Adequate plumbing skills.
Icons That Appear In This Manual
Failure to follow this instruction can result in
personal injury or damage to the equipment.
Failure to follow this instruction can result in
damage to the equipment.
NOTE: NOTE: This will make the process easier if followed.
SAFETY INFORMATION
• Do not use lead-based solder for sweat solder
connections.
• The drain line must be a minimum of 1/2" diameter. Use
3/4" pipe if the backwash flow rate is greater than 5 GPM
(18.9 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.
General
• 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 34ºF (1ºC)
and 120ºF (49ºC).
• Operating water temperature is between 34ºF (1ºF) and
100ºF (38ºC).
• Working water pressure range is 20 to 125 psi (1.38
to 8.61 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.
CALIFORNIA PROPOSITION 65 WARNING
This product contains chemicals known to the
State of California to cause cancer or birth
defects or other reproductive harm.
Electrical
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.
Mechanical
• Do not use petroleum based lubricants such as
petroleum jelly, oils, or hydrocarbon based lubricants.
Use only 100% silicone lubricants.
• All plastic connections should be hand tightened.
Plumber's 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.

Logix Series Controllers
See: Determining If You Have a 740 or 760 Control on page
19 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 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.

Time & Day
• 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.

Operating Pressure:20 -125 psi or 1.4 – 8.8 kg/Centimeter
Acceptable Salt Type: Sodium Chloride – Pellet or solar salt for water softeners
All Systems above tested at 35psi +/- 5 psi, pH of 7.5+/- 0.5, Capacity Testing Flow Rate = 50% of the rated service flow rate for the various size systems.
These water softener systems have been tested by WQA and conform to NSF/ANSI 44 for specific performance claims as verified and substantiated by
test data. The rated salt efficiencies above were also determined in accordance with NSF/ANSI 44 and are only valid at the salt dosage referenced above.
An efficiency rated water softener is a demand initiated regeneration (DIR) softener which also complies with specific performance specifications intended
to minimize the amount of regenerant brine and water used in its operation. Efficiency rated water softeners shall have a rated salt efficiency of not less
that 3350 grains of total hardness exchanged per pound of salt (based on NaCl equivalency) (477 grams of total hardness exchanged per kilogram of salt),
and shall not deliver more salt than its listed rating. The rated efficiency of the water softener, the salt dosage at that efficiency, the capacity at that salt
dosage and that of the efficiency is onl y valid at the stated salt dosage. Efficiency is measured by a laboratory test described in NSF/ANSI 44. The test
represents the maximum possible efficiency the system can achieve. Operational efficiency is the actual efficiency achieved after the system has been
installed. It is typically less than the efficiency due to individual application factors including water hardness, water usage, and other contaminants that
reduce the water softener’s capacity. These systems are not intended to be used for treating water that is microbiologically unsafe or of unknown quality
without adequate disinfection before or after the system. Refer to the system Installation and Service Manuals for set-up and programming instructions.

System Regeneration Cycles
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.

5. Fast Rinse (Downflow) — Cycles C5, C7:
The control directs water down through the resin bed and
up through the 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 34°F (1°C) and below
120°F (49°C).
• Water pressure below 125 psi (8.61 bar) and above
20 psi (1.4 bar).
• In Canada the water pressure must be below
100 psi (6.89 bar).
• 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.

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.
EQUIPMENT INSTALLATION CONTINUED
WARNING:
WARNING:
WARNING:
• 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.

Figure 7 Typical Globe Valve Bypass System
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.
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.
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.
Drain Line Connection
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 sinktype trap must be used.
Secure the end of the drain line to prevent it from moving.

EQUIPMENT INSTALLATION CONTINUED
WARNING:
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.
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 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 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.

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.
