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 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.
*Teflon is a trademark of E.I. duPont de Nemours.

10 General Warnings And Safety Information
Rev B
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 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 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 (5-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:
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 allows the air and water to hydraulically balance in the
valve before continuing the regeneration.

General Warnings And Safety Information 11
Rev B
5. 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.

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 4 and 5
show the three common bypass methods.

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 break the connections. When the 1265 or 256 bypass valve is used,
only hand tighten the plastic nuts.

16 Drain Line Connection
Rev B
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) 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.
Figure 6
Drain Line Connection
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.

Air Gap
Drain

Overflow Line Connection 17
Rev B
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 7). 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.
Figure 7
Overflow 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 6). Always allow an air gap between the drain line and the
wastewater to prevent the possibility of sewage being back-siphoned
into the conditioner.
