Outdoor Locations
When the water conditioning system is installed outdoors,
several items must be considered.
•Moisture – The valve and control 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, or upwards spray from
sprinkler.

Location Selection
Location of a water conditioning system is important. The
following conditions are required:
•Level platform or floor.
•Room to access equipment for maintenance and
adding regenerant (salt) to tank.
•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.

Installation
All plumbing must conform to local codes. The two tanks
should be plumbed to an interconnecting manifold,

connections. Hand tighten the nuts.
Do not use tools to tighten plastic
Location Selection
The following considerations must be taken into account
when selecting the location for the water conditioning
system.
•Locate the system as close to a drain as possible.
•If supplementary water treating equipment is
required, make sure that adequate additional space
is available. Locate the brine tank in an accessible
place so that salt can be easily added.
•Do not install any system with less than 10 feet
(3 m) of piping between the outlet of the conditioners
and the inlet of the water heater. Water heaters can
transfer heat down the cold water pipe into the
control valve. Hot water can severely damage the
conditioners.
A ten-foot (3-m) total pipe run (including bends, elbows,
etc.) is a reasonable distance to prevent hot water
damage. A positive way to prevent hot water from flowing
from a heat source to the conditioners is to install an
expandable accumulator tank before the hot water heater.
Always conform to local codes.
•Do not locate the unit in an area where the ambient
temperature is ever below 34
o
120
F (49oC).
•Maximum allowable water temperature is
o
100
F (38oC).
•Do not install the unit near acid or acid fumes.
•Do not expose the unit to petroleum products.
o
F (1oC) or over
WARNING:
Do not use petroleum grease on
gaskets when connecting bypass plumbing. Use
only 100% silicone grease products when
installing any Autotrol brand valve. Non-silicone
grease may cause plastic components to fail
over time.
WARNING:
The inlet water must be connected
to the inlet port of the valve. When replacing nonAutotrol valves, the inlet and outlet may be
reversed. Ensure that the plumbing is not
installed in the oppposite order. Tank media may
be pushed into the valve.
Water Line Connection
A bypass valve system must be installed to accommodate
occasions when the water conditioning system must be
bypassed for supplying hard water or servicing. See
Figures 7 and 8.

Drain Line Connection
Note:
here. Local codes may require changes to the following
suggestions. Check with local authorities before installing
a water conditioning system.
The system should be above, and not more than 20 feet
(6.1 m) from a drain. Connect an appropriate fitting and
1/2-inch (1.3-cm) plastic tubing to the drain line
connection on the rear of the control valve.
If the backwash flow is more than 5 gpm or if the unit is
located more than 20 feet (6.1 m) from the drain, use 3/4inch (1.9-cm) tubing for runs up to 40 feet (12.2 m). Also,
purchase appropriate fitting to connect the 3/4-inch
tubing to the 1/2-inch NPT drain connection.
If unit is located where the drain line must be elevated, you
may elevate the line up to 5 feet (1.5 m) providing the run
does not exceed 15 feet (4.6 m) and water pressure at the
conditioners is not less than 40 psi (2.8 bar).
Where 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 a 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 11).
Standard commercial practices are expressed
Brine Line Connection
It is recommended that separate brine lines be used for
each tank.
A regenerant tank aircheck is not required when using a
255 valve with the built-in aircheck. Doing so will cause
premature checking and may result in hard water or
regenerant tank overflow. The 255 aircheck is available
standard with a 1/4" NPT tube compression fitting. The
use of Teflon tape is required on the 1/4" NPT connection.
Install an appropriate fitting onto the 1/4-inch male NPT
connection on the air check (Figure 9), and install a length
of 3/8-inch polyethylene tubing between the air check
fitting and the brine pick-up tube at the brine tank. If you
are using a brine valve remove the ball in the air check to
avoid possible premature checking.

Brine Tank Overflow Line Connection
In the event of a malfunction, the brine tank overflow
connection directs overflow to the drain instead of spilling
it on the floor where it could cause water damage.
Complete the following steps to connect the overflow
fitting to the brine tank:
1. Locate the fitting hole on the side of the brine tank.
2. Insert the overflow fitting (not supplied) into the tank
and tighten with the plastic thumb nut and gasket as
illustrated in Figure 10.

Brine Tank
Normally one brine tank is needed for each tank. The use
of block salt or rock salt is not recommended. If a brine
shelf is used, two brine tanks are required. This is due to the
increased time needed to produce a concentrated brine
solution when using a salt shelf. If rapid multiple
exhaustions and regenerations are anticipated, do not use
a salt shelf even if two brine tanks are used.
120 VAC AC Adapters:
Make sure power source matches the rating printed on the
AC adapter.
Note:
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 control will display four dashes (- - :- -)

Disinfection of Water Conditioning
Systems
The materials of construction in the modern water
conditioning system 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.
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.
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
These materials are satisfactory for use with polystyrene
resins, synthetic gel zeolite, and bentonites.
5.25% Sodium Hypochlorite
These solutions are available under trade names such as

System Operation
Treated Water (Downflow)
Untreated water is conditioned as it flows through the
resin bed and up the riser.
Backwash (Upflow) – Cycle C1
Flow is reversed by the control valve, directed down
the riser, up through the resin bed and sent to drain.
The bed is expanded and debris is flushed to the
drain.
Regenerant Draw (Downflow) – Cycle C2a
Water passes through the injector and regenerant is
drawn from the regenerant tank. The regenerant is
directed to the resin bed. The hardness ions are
displaced by sodium ions. Regenerant draw is
completed when the air check closes.
Slow Rinse (Downflow) – Cycle C3
Water flow moves the regenerant through the resin
at a specific rate and rinses to the drain. The resin is
regenerated.
a
Repressurization – Cycle C4
Pressure is balanced in the valve before continuing
the regeneration.
Fast Rinse (Downflow) - Cycle C5
Water passes through the resin bed and up through
the riser to drain. All remaining regenerant residual is
rinsed from the resin bed.
2nd Backwash (Upflow) - Cycle C6
Flow is identical to C1 Backwash. The resin is
reclassified.
2nd Rinse (Downflow) - Cycle C7
Flow is identical to C5 Fast Rinse. The resin bed is
rinsed to quality.
Regenerant Refill – Cycle C8
Water is directed to the regenerant tank to create
regenerant for the next regeneration.

easier to view water flow and motion in the tank.
It’s recommended that you do not put regenerant
It is required that the control be quick cycled to specific
regeneration cycles when placing the conditioner into
operation. This will ensure that all of the air in the tank and
valve is purged. The process also provides a check for leaks
and functioning of the brine system. Please perform the
following steps for quick cycling the control, before
proceeding to start-up.
1. With the control in the treated water position, Press and
hold the REGEN button on the controller for 5 seconds.
This will initiate a manual regeneration. The control will
display a solid hourglass indicating that the motor and
camshaft are turning to the backwash cycle (C1). When
the control reaches the backwash cycle, the total
regeneration time remaining will be displayed. Pressing
the SET button will display the specific cycle time
remaining.
2. Press and release the UP and SET buttons to move the
control to the Regenerant Draw cycle (C2).
3. Repeat Step 2 to advance to each cycle.
Before the final filling of the media tank with water
check that:
– the nearest water faucet is completely closed.
– the valve drain line is properly routed to a drain
– the regenerant tank is empty and the regenerant
hose is connected to the valve
– the water supply valve is off.
5. Press and hold the button on the controller for 5
seconds. This will initiate a manual regeneration.
The control will display a solid hourglass indicating
that the motor and camshaft are turning to the
backwash cycle (C1). When the control reaches the
backwash cycle, the total regeneration time
remaining will be displayed. Pressing the SET button
will display the specific cycle time remaining.
6. While the controller is in cycle C1 (Backwash), open
the water supply valve very slowly to approximately
the ¼ open position. Water will begin to enter the
media tank. Any air remaining will begin to be purged
to drain as the media tank fills with water.
WARNING:
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.
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.
Allow water to run to drain until the water runs clear
from the drain line. This purges any debris from the
media bed.
If opened too rapidly or too far,
Note:
treated water position from any regeneration cycle. Press
the UP and SET buttons (about 5 seconds) until the
hourglass icon begins flashing. The control will now skip
all remaining regeneration cycles.
255 Alternating and parallel tank systems have one Logix
764 control that is mounted on tank 1. Tank 2 has a blank
faceplate and the valve is controlled by the Logix 764
control on tank 1.
The control can be sent directly back to the
4. Add water to the regenerant tank.
A. With a bucket or hose add approximately 4
gallons (15 liters) of water to the regenerant
tank.
7. Check Regenerant Draw.
A. Quick cycle the control to the C2 regenerant
draw/slow rinse position .
Note:
slight delay before you can advance to the next cycle.
There will be a pause after the regenerant draw and slow
rinse cycles. This cycle (C4) is a repressurization cycle and
is designed to allow the water pressure to equalize on
each side of the valve discs. Allow the control to
repressurize (3 minutes) before cycling the control to the
regenerant tank refill position.
19
As you advance through each cycle there will be a
B. C2 will be displayed. With the control in this
position, check to see that the water is being
drawn out of the regenerant tank. The water
level in the regenerant tank should recede
very slowly.
Page 20
C. Observe that water is being drawn from the
regenerant tank for at least three minutes. If
the water level does not recede, check all
regenerant line connections for air leaks.
255 Alternating tank systems have one Logix 764 control
that is mounted on tank 1. Tank 2 has a blank faceplate
and the tank 2 valve is controlled by the Logix 764 control
on tank 1.
8. If the water level is receding from the regenerant tank
you can quick cycle the control to the C8 Regenerant
tank refill position.
A. The control will cycle to the regenerant tank
refill cycle, and water will be directed down
through the regenerant line to the regenerant
tank. Let the water flow through the line until
all air bubbles have been purged from the
line. Note: Do not let the water flow down the
line to the tank for more than one to two
minutes, or the tank may overfill.
9. Repeat steps 4 and 8 for each additional tank.
10. Finally, turn on a faucet plumbed after the water
conditioner. Run the faucet until the water runs clear.
11. Add the appropriate amount of regenerant to
regenerant tank.

and functioning of the brine system.
After the initial power up and programming, tank 1 will be
in standby and tank 2 will be in service.
Before the final filling of the media tanks with water,
check that:
– the nearest water faucet is completely closed.
– the valve drain line is properly routed to a drain.
– the regenerant tank is empty and the regenerant
hose is connected to the valve.
– the water supply valve is partially open
– valve bypasses are in service positions.
During this process the valves will need to be quickly
advanced to the next cycle. To quick cycle press

Manual Regeneration Options
Note:
while the other tanks are isolated. Water for backwash
would not be available.
The 764 control features several options that offer
additional flexibility for manually regenerating the
conditioner. On alternating systems the tank in standby
will move through regeneration to service. The tank in
service will move through regeneration to standby. On
parallel systems, the tank with the lowest remaining
capacity will regenerate.
Delayed Manual Regeneration
Press and release the REGEN button to start a delayed
manual regeneration. The Regeneration icon on the
display will flash indicating a regeneration will start when
the time of day reaches the programmed time of
regeneration. Pressing the REGEN butt on again will turn off
the regeneration icon and cancel the delayed
regeneration.
Immediate Manual Regeneration
Pressing and holding the REGEN button for three seconds
starts an immediate manual regeneration. A solid
regeneration icon will be displayed. The control will
immediately begin a regeneration on the tank in service.
The tank in service (on-line) cannot be regenerated
Delayed Second Regeneration
Pressing and releasing the REGEN button while the control
is in regeneration will program the control for a delayed
second regeneration. A flashing x2 icon next to the
regeneration icon will appear indicating a second
regeneration will start when the time of day reaches the
programmed time of regeneration. The delayed second
regeneration will be performed on the new tank in service.
For alternating and parallel systems, each tank will
regenerate once.
Double Immediate Manual Regeneration
Back-to-Back manual regenerations are initiated by
pressing and holding the REGEN button for three seconds
while the control is in the regenerating mode. A solid x2
icon next to the regeneration icon will appear indicating a
second manual regeneration will start immediately after
current regeneration is complete. For alternating and
parallel systems each tank will regenerate once. Single
tank systems will regenerate twice back-to-back.
27
Page 28
Regeneration Modes for Parallel
Systems
Parameter P16 is used to determine the method for
demand initiated regeneration. Four regeneration modes
are possible.
•P16 = 0, Delayed Regeneration with a Smart Reserve
Regenerations will start only at the Time of
Regeneration entered in P2. A tank is regenerated if
the capacity remaining in that tank is below the
minimum required capacity needed to meet the next
days calculated water usage requirement. The next
days water usage number is based on the daily
average water usage held in memory plus a 20%
reserve. If necessary both tanks will be regenerated
sequentially beginning with the most exhausted tank.
This option allows the control to vary the reserve, and
therefore the decision to regenerate, based on the
actual daily water usage pattern for the location at
which it is installed. See Table 5.
•P16 = 1, Delayed Regeneration with a Fixed Reserve
Regenerations will start only at the Time of
Regeneration entered in P2. A tank is regenerated if
the capacity remaining in that tank is below the
percentage entered in P17.
If either tank’s capacity is overrun by 50% a
regeneration will take place. The control will also
cause both tanks to be regenerated sequentially the
next T ime of Regeneration regardless of how much
water is used during that 24 hour period. This feature
is to help recover a severely exhausted bed. See
Table 6.
•P16 = 2, Immediate Regeneration - Fixed
R e s e r v e / D e l a y e d R e g e n e r a t i o n - S m a r t R e s e r v e
This option uses the features of both option 0 and
option 3. This is the most versatile of regeneration
options. Option number 2 provides all the advantages
of variable reserve based on the actual amount of
water that is used each day plus the capability to
react to the excessive water usage days that occur
occasionally. See Table 7.
•P16 = 3, Immediate Regeneration - Fixed Reserve
Regenerations are started immediately when a tank
reaches zero or when the system capacity remaining
(capacity remaining in both tanks) drops below the
reserve capacity programmed in P17. To prevent
hard water this reserve should be set large enough to
provide conditioned water during the regeneration of
the most exhausted tank. See Table 8.
