Logix Series Controllers See Determining If You Have a 742 or 762 Control on page 27 to identify
your controller.
742 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.
762 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.
For 5-cycle filter applications, see page 40 for setting details.

10 General Warnings And Safety Information
Rev D
General
• Observe allwarnings thatappear 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 34°F (1°C) and 120°F
(49°C).
• Operating water temperature is between 34°F (1°F) and 100°F (38°C).
• 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 regenerantsalts designed for water softening. Do not use ice
melting, block, or rock salts.
• Follow state and local codes for water testing.Do not use waterthat is
micro biologically unsafe or of unknown quality.
• When filling mediatank, 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 regeneranttank. The brine is then directed down through the
resin bed and upthrough the risertube to the drain. The hardness ions
are displaced by sodium ions and are sentto the drain. The resin is
regenerated during the brine cycle. Brinedraw is completed when the
air check closes.
4. Repressurize Cycle (Hard Water Bypass Flapper Open) — Cycle C4:
This cycle allows the air and water to hydraulically balancein the
valve before continuing the regeneration.

General Warnings And Safety Information 11
Rev D
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 remainingbrine residualis 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 regeneranttankat a controlled rate, to create brine for
the next regeneration.

Outdoor Locations
When the water conditioning system is installed outdoors, several items
must be considered.
• Moisture — The valve and 700 controllerare 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:constantheavy 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 notdegrade 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 andcontroller is
necessary.
• Temperature — Extreme hot or cold temperaturesmay cause damage
to the valve or controller.
Freezingtemperatureswillfreeze thewaterinthevalve.This willcause
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 andvalve have been designed to keep allbut
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 allwater conditioning
systems. Bypass valvesisolate 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.

Rev D
Drain Line Connection
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) foreach additional 10 psi(.69 bar) of water pressure at the drain
connector.
4. Where the drainline is elevated but empties into a drain below the
level of the control valve, form a7-inch (18-cm)loop atthe far end of
the line so that the bottom of the loop is level with the drain line
connection. This willprovide an adequate siphon trap.
WARNING: The inlet water must be connected to the inlet port of the
valve. When replacing non-Autotrol 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 breakthe connections.Whenthe 1265or 256bypassvalveisused,
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.

18 Overflow Line Connection
Rev D
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.
Figure 8
Drain Line Connection
Overflow Line Connection
(not used with 3-cycle filter system)
In the event of a malfunction, the regenerant TANK OVERFLOW will direct
“overflow” to thedrain instead of spilling on thefloor. Thisfitting should be
on the side of the cabinet or regenerant tank. Most tank manufacturers
include a post for the tank overflow connector.
Toconnect the overflow line, locate hole onside of tank. Insert overflow
fitting into tank and tighten with plastic thumb nut andgasketas 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 drainline 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.
Right Way
Air Gap
Drain
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 toprevent the possibility of sewage beingback-siphoned
into the conditioner.

Regenerant Line Connection 19
Rev D
Figure 9
Overflow Line Connection
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 regenerantline is secure
and free from air leaks.Even a smallleakmay cause the regenerantline to
drainout, and the conditionerwill not draw regenerantfrom the tank. This
may also introduce air into the valve causing problems with valve
operation.
Mostinstallations utilize a tank check valve. This is not necessary when
using the 255 valve with the built-in aircheck. Using atank check valve
with the 255 valve with aircheck will resultin premature checking of the
aircheck valve, before the tank is empty.
