Installation
All plumbing and electrical connections must conform
to local codes.
Inspect unit carefully for carrier shortage or shipping
damage.
Location Selection
1. The distance between theunit anda drain should be
as short as possible.
2. If it is likely that supplementary water treatment
equipment will be required, make certain adequate
additional space is available.
3. Do not install any unit closer to a water heater than
a total run of 10 feet (3 m) of piping between the
outlet of the conditioner and the inlet to the heater.
Water heaters can sometimes overheat to the
extent they will transmit heat back down the cold
pipe into the unit control valve.
Hot water can severely damage the conditioner. A
10-foot (3-m) total pipe run, including bends,
elbows, etc., is a reasonable distance to help
prevent this possibility. A positive way to prevent
hot water flowing from heat source to the
conditioner, in the event of a negative pressure
situation, is to install a check valve in the soft
water piping from the conditioner. If a check valve
is installed, make certain the water heating unit
is equipped with a property rated temperature
and pressure safety relief valve. Also, be
certain that local codes are not violated.
4. Do not locate unit where it or its connections
(including the drain) will ever be subjected to room
temperatures under 34oF (1oC) or over 120oF
(49oC).
5. Do not install unit near acid or acid fumes.
Water Line Connection
The installation of a bypass valve system is
recommended to provide for occasions whenthe water
conditioner must be bypassed for hard water or for
servicing.
The most common bypass systems are the Autotrol
Series 1265 bypass valve (Figure 1) and plumbed-in
globe valves (Figure 2). Though both are similar in
function, the Autotrol Series 1265 bypass offers
simplicity and ease of operation.
Figure 1
Figure 2
Drain Line Connection
Note: Standard commercial practices are expressed
here. Local codes may require changes to the following
suggestions.
1. Ideally located, the unit will be above and not more
than 20 feet (6.1 m) from the drain. For such
installations, using an appropriate adapter fitting,
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 more than 20 feet
(6.1 m) from drain, use 3/4 -inch (1.9-cm) tubing for
runs up to 40 feet (12.2 m). Also, purchase
appropriate fitting toconnect the 3/4-inch tubingto
the 3/4-inch NPT drain connection.
3. If the unit is located where the drain line must be
elevated, you may elevate the line up to 6 feet
(1.8 m) providing the run does not exceed 15 feet
(4.6 m)and water pressure at conditioner is not less
than 40 psi (2.76 bar). You may elevate an
additional 2 feet (61 cm) for each additional 10 psi
(0.69 bar).
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.
5. Where the drain empties into an overhead sewer
line, a sink-type trap must be used.
IMPORTANT: Never insert drain line into a drain, sewer
line or trap. Always allow an air gap between the drain
line and the wastewater to prevent the possibility of
sewage being back-siphoned into the conditioner.
Figure 3
Note: Standard commercial practices have been
expressed here. Local codes may require changes to
these suggestions.
Placing Conditioner into Operation
Afterall previous steps have been completed the unit is
ready to be placed into operation. Follow these steps
carefully.
1. Remove control valve cover.
Note: The following steps will require turning the
indicator knob (Figure 4 and Figure 5) or the cycle
indicator (Figure 7) to various positions. Manually
rotate the camshaft COUNTERCLOCKWISE only
until indicator knob and cycle indicator points to
desired position. (See manual regeneration
sections for each control’s manual operation.)
2. Rotate indicator knob or cycle indicator
COUNTERCLOCKWISE until it points directly to
the word BACKWASH.
3. Fill media tank with water.
a. With watersupplyoff,placethebypassvalve(s)
into the “service” position.
b. Open water supply valve very slowly to
approximately the 1/4 open position.
IMPORTANT: If opened too rapidly or too far, media
may be lost. In the 1/4 open position, you should hear
air escaping slowly from the drain line.
c. When all of the air has been purged from the
tank (water begins to flow steadily from the
drain), open the main supply valve all the way.
d. Allow water to run to drain until clear.
e. Turn off water supply and let the unit stand for
about five minutes. This will allow all trapped air
to escape from the tank.
4. Place the conditioner into operation.
a. Advance the indicator knob or cycle indicator
COUNTERCLOCKWISE to the SERVICE
position and run water from a nearby faucet
until the water is clear.
Electrical Connection
100 VAC, 115 VAC, and 230 VAC units: Remove twist
tie from the power cord and extend cord to its full
length. Make sure the power source matches the rating
printed on the control. Be certaina wall switch does not
control the outlet.
12 VAC: Connect the plug of the transformer (supplied)
secondary cable to the mating socket at the rear or
bottom of the timer housing. Be certain the transformer
is secure and is plugged into a power sourceof correct
voltage that is not controlled by a wall switch.

1. Set daysofregeneration on skipper wheel (Figure 4).
•Pull all skipper pins outward (away from
control).
•Rotate skipper wheel until day arrow points to
current day or number 1.
•Depress skipper pin(s) at day(s) for which
regeneration is desired.
2. Set the time of day.
•Grasp timer knob and pull outward.
•Rotate in either direction until the timer arrow
points to the actual time of day.
•Release timer knob.
Note: with the time of day properly set, the conditioner
will regenerate at about 2:30 a.m. If you prefer to have
the unit regenerate at an earlier or later time, simply set
current time-of-day accordingly (e.g., to have the unit
regenerate at4:30 a.m. - two hours later - set the clock
two hours earlier than the actual time of day.)
Note:Thetimerlockingpinshouldalwaysbehorizontal
(Figure 4) during operation.
Guest Cycle
When abnormally high water usage exhausts your
water conditioner’s capacity ahead of schedule, an
extra regeneration can be achieved. Depress the
indicator knob on the 440i (Figure 4) with a wide-blade
screwdriver and turn COUNTERCLOCKWISE to
START to initiate a regeneration. It will take a few
minutesforregenerationto start.Anormalregeneration
will take approximately two hours.
Manual Regeneration
Electricity is used only to run the control and to rotate
the camshaft. All other functions are operated by water
pressure. Therefore, in the event of a power outage, all
the regeneration positions may be dialed manually by
depressing the indicator knob and turning
COUNTERCLOCKWISE (Figure 4). The following
cycle times should be used for proper regeneration:
BACKWASH - 20 minutes
FAST RINSE - 10 minutes

Note: The NEXT DAY day pin is noted on the timer
face. Depressing this pin will insure a regeneration the
next day at approximately 2:00 a.m. Since the calendar
cap progresses CLOCKWISE, depressing the day pin
immediately COUNTERCLOCKWISE will insure a
regeneration the following day at 2:00 a.m. This
progression is noted on the timer face as “FUTURE

Note:With the time of day properly set, the conditioner
will regenerate at about 2:00 a.m. If you prefer to have
the unit regenerate at an earlier or later time, simply set
the current time-of-day accordingly (e.g., to have the
unit REGENERATE at 4:00 a.m. - two hours later - set
the clock two hours earlier than the actual current time).
Note: Do not rotate the Calendar Cap by hand; the
clock dial indexes it daily. To manually index the
Calendar Cap, rotate the Clock Dial CLOCKWISE one
complete turn for every day to be indexed.
Figure 6
How to Adjust the Backwash Time
With the indicatorknob in the BACKWASH COMPLETE
position (Figure 6), rotate the Backwash Dial
COUNTERCLOCKWISE at least one full turn to cancel
the previous setting. A light clicking will be replaced by
a heavier clicking when the previous setting is
cancelled. Then, rotate the Backwash Dial to the
desired backwash time. The numbers are minutes of
backwash per regeneration.
Manual Regeneration
Electricity is used only to run the control and to rotate
the camshaft. All other functions are operated by water
pressure. Therefore, in the event of a power outage, all
regeneration positions may be dialed manually. Grasp
the indicator knoband turn COUNTERCLOCKWISEto
each regeneration cycle (rotation is much easier if you
grasp the camshaft with your free hand and turn it at
the same time). The following cycle times should be
used for proper regeneration.
BACKWASH - 20 minutes
FAST RINSE - 10 minutes
960F Control
Figure 7
Programming
This section covers all aspects of programming the
control. The control is shipped from the factory with
default values for most parameters. These default
values will result in a system capacity of 100 gallons
(1 cubic meter). While the control may operate with
these values, the following parameters must be
changed to meet the actual operating conditions:
Refill Controller Value,BrineDrawRate, and Slow Rinse
Time parameters are not required for 960F operation,
but should be adjusted as instructed to achieve the
shortest possible backwash cycle time.
Note that some parameters have a single unit of
measure option. Other parameters have dual units
such as Capacity which can be entered in gallons or
cubic meters. To select which units are active, look for
a comment in the NOTES column of Tables 1 and 2. It
will reference another parameter that selects which
units are active. For example, parameter P12 (Table 2)
selects U.S. units if it is set to “0” and metric if it is set
to “1”.

Level I Parameters (Table 1)
Level I parameters are identified as those that have an
LED indicator on the front panel. The green indicator
illuminates next to the name of the active control
settings. The end user has access to all of these
parameters. In general, pressing the down arrow (↓)
button displays the Level I Parameters in the following
order:
•Time of Day
•Time of Regen
•Factor A
•Factor B
•Capacity
If you continue to press the down arrow (↓) button, the
parameters startover withTime of Day. Pressingthe up
arrow (↑) button displays the parameters in reverse
order. Refer to Table 1 for a description of these
parameters and the available ranges for each
parameter.
Press the SET button and the far right digit of the
display starts flashing. If you want to change this
number, press the up arrow (↑) button to increase the
number or the down arrow (↓) button to decrease the
number. To skip the number without changing, press
the left arrow (←) button. When you reach the far left
digit, pressing the left arrow (←) button will return you
to the far right digit.
Note: If you press and hold either the up arrow (↑)
button or the down arrow (↓) button for more than one
second, the flashing number will increment or
decrement at the rate of 10 counts per second.
When the number is correct, press the left arrow (←)
button. The far right digit stops flashing and the next
digit to the left starts flashing. You can only change
the flashing number. Continue changing numbers
until you reach the desired setting. Press the SET
button. The numbers stop flashing and the control
accepts the new setting. After approximately 30
seconds, the control starts alternating the display
between Time of Day and Capacity.
Note:If the new setting is not accepted because itwas
outside the allowable range, the old value will be
displayed.
Time of Day
Press the SET button. The display will show the Time
of Day with the minutes digit blinking. If you want to
change this number, press the up arrow (↑) button to
increase the number or the down arrow (↓) button to
decrease the number. To skip the number without
changing, press the left arrow (←) button. The first
number stops flashing and the next number starts
flashing. You can only change the flashing number.
When you have reached the far left digit, pressing the
left arrow (←) button returns you to the far right digit.
Continue changing numbersuntil you each the desired
setting. Press the SET button again to enter the value.
Time of Backwash
The next value displayed is the Time of Backwash. It is
similar to Time of Day programming. It has a default
value of 2:00 a.m. If 2:00 a.m. is acceptable, press the
down arrow (↓) button. If this is not acceptable, press
the SET button and change the numbers. Press the
SET button again to enter the value.
Factor A
Factor A is the next value displayed. The 960F control
usesthisvaluetocalculatethesystemcapacity.Factor
A must be set to 10 (100 for metric units) for the
960F control to accurately calculate system
capacity. The default value is 10 (100 for metric units).
If the Factor A setting is not correct, press the SET
button and change the value. Press the SET button
again to enter the new value.
Factor B
Factor B is the next value displayed. This value is used
by the control to calculate the pause for the refill cycle.
Because the refill cycle is not required for 960F
operation, Factor B should be set to 0.2 (0.1 for metric
units). This is the minimum setting and will cause the
control to skip the refill cycle, thereby shortening the
backwash cycle time. The default value for Factor B is
0.2 (0.1 for metric units). To change Factor B, press the
SET button and change to the correct value. Press the
SET button again to enter the new value.
Capacity
Capacity is the next value displayed and is used by the
960F control in combination with Factor A to determine
the capacity of the filter. The Capacity value should be
set to the actual capacity of the filter expressed as
gallons/100 (cubic meters/10 for metric units).
Example: If the actual filter capacity is 950 gallons,
enter 9.5 for the Capacity setting. The default value for
Capacity is 1.0 (0.1 for metric units). To change the
Capacity setting, press the SET button and adjust the
correct value. Press the SET button again to enter the
new value.
At this time, all of the Level I parameters are
programed.The display will alternate between the Time
of Day and Capacity if no keys are pressed for 30
seconds. The Capacity value displayed is the volume
remaining in gallons (cubic meters for metric) before a
backwash is needed.

8
Note: The 960F control uses Factor A and Capacity
settings to calculate the actual system capacity. If the
actual system capacity is in excess of 9999 gallons
(99.99 cubic meters) the control will display 9999
(99.99) until the water usage has dropped the
remaining capacity below that number. When water is
flowing through the system, the colon in the Time of
Day display will blink.
To complete the initial programming of the 960F,
proceed to the Level II Parameters.

mention these parameters, so the end user does not
normally have access to these values. To access Level
II Parameters, simultaneously press and hold the down
arrow (↓) and up arrow (↑) button for three seconds.
If the control was alternating between Time of Day and
Capacity when the above button sequence is entered,
the display shows P1. If a different Level I Parameter
was displayed, the display, shows the “P” number for
that parameter. Refer to Table 2 to find the “P” number
associated with each parameter.
Use the up arrow (↑) button or the down arrow (↓)
button to move from one parameter to the next. The

Refill Control
The Performa Valve with the 960F control is designed
for use as a three cycle filter valve and does not include
a refill control. However, the software program used in
the 960F control is also used for the five cycle softener
control, and requires a refill controllervalue to calculate
how long to pause the cam shaft in the refill position. In
general, a small refill control value results in a long
pause, and a large refill control value results in a short
pause. For 960F operation, the refill Control Value
should be set to 99 to avoid delays during backwash.
The default value for Refill Control Value is 99.
Brine Draw Value
Brine Draw Value P7 is used to calculate the amount of
time required for the brine draw cycle. Because the
960F does not require a brine draw cycle, the Brine
Draw Value should be set to 99 to avoid delays during
backwash.
•Thiscontrol does notuse parameterP8. Noentry is
needed for this parameter.
Backwash Time
Parameter P9 is used to set the backwash time in
minutes. The default in P9 is 14 minutes. If a different
backwash time is desired, press the SET button and
enter a new value.
Slow Rinse Time
Parameter P10 Slow Rinse Time is used to calculate
how long to pause the cam shaft for the slow rinse
cycle. For 960F operation, the Slow Rinse time should
be set to 8 minutes to avoid delays during backwash.
The default value for Slow Rinse Time is 8 minutes.
Fast Rinse Time
Parameter P11 determines the fast rinse time. The
default value is 9minutes. Ifa differentfast rinse time is
desired, press the SET button and enter a new value.
•Parameter P12 selects the units of measure. Be
sure that this is set to the correct value before
entering any data for parameters P3, P4, or P5.
•Parameter P13 selects the clock display mode. If
the 12 hour mode is selected, a PM indicator is
used. If the 24 hour mode is selected, the indicator
is not used.
•Parameter P14 is used to set the calendar override
feature. The default value is zero. If set to zero, the
feature is disabled. Refer to Calendar Override for
more information on the calendar override feature.
•Parameter P15 selects a variable reserve type, 0 to
3. For more information on reserve options, refer to
Reserve Options.
•Parameter P16 is used to calculate the initial
average daily water usage values. The control
multiplies the total capacity by the percentage
entered for Parameter P16 and uses that value as
the initial average daily usage for each day of the
week until water usage establishes new averages.
The default is set for 30% of the capacity. In most
installations this is acceptable.
•Parameter P17 has been preset to 4. Do not
change this setting. P17 must be set to 4 for
proper 960F operation. Improper backwashes will
occur if P17 is set to something other than 4.
•Parameter P18 allows the installer to lock the
Factor B and Capacity values so they cannot be
changed. When Parameter 18 is set to 1, those two
settings can only be viewed when the control is in
the Level II mode. The settings will be skipped
when the control is in the Level I mode. When
Parameter 18 is set to zero, the Factor B and
Capacity can be viewed and changed in either
Level I or Level II.
•Parameter P19 is used at the factory to enter
default values. This parameter does not need to
be changed. Using this parameter will erase the
values for all other parameters and replace them
with default values. P19 should be set at 99 and
should not be changed.

Regeneration
When the control begins a regeneration, the display will
alternate between Time of Day and Regen Time
Remaining. The Regen Time Remaining is shown in
minutes. The control will start and stop an internal
motor which drives the cam gear through the various
backwash positions. The control uses the information
entered in the parameters shown in Table 2 to
determine how long each part of the cycle should last.
If power fails during a regeneration cycle, the cycle
completes normally when the power is restored.
Note: The REGEN button is only active when the
display is alternating between Time of Day and
Capacity. When programming Level I or II parameters,
the REGEN button is not active.
The Regen Time Remaining will continue to count
down until the cam gear reaches the Service position.
Manual Regeneration
To initiate a manual regeneration, press the REGEN
button.Thisbutton islocatedon thefrontofthecontrol.
When you press the REGEN button, the control
performs a full regeneration of the filter.
If you press this button again more than one minute
after regeneration begins, but before the
regeneration is complete, a second regeneration
will start whenthe first regeneration isfinished. The
display will freeze and only show the Regen Time
Remaining as an indication that the second
regeneration will be performed. When the first
regeneration is complete, the second one will begin
and the display will alternate between Time of Day and
Regen Time Remaining.
Automatic Regeneration
There are two ways to have the control automatically
initiate a regeneration: calendar override or normal
metered water usage.
Calendar Override
This feature is set in parameter P14. It can be set for 1
to 30 days. If it is set to zero, this feature is disabled.
When this feature is active, the control keeps track of
the number of days since the last backwash and when
that number equals the value set in P14, a backwash is
automatically started at the Time of Backwash set in
P2.
Normal Metered Water Usage
The control compares the water usage to the
calculated volume capacity of the system. The control
uses the Capacity parameter P5 and the Factor A
parameter P3 to calculate the volume capacity of the
system. It also uses a reserve value to determine if a
backwash is necessary. If the water usage since the
last backwash is greater than the system capacity
minus the reserve, a backwash is needed.
Note: If the water usage exceeds 150% of the system
capacity between backwashes, the control will
automatically call for a second backwash the next day
even if no water used.
Reserve Options
There are two types of reserve options for this control:
fixed reserve and historical water usage pattern. They
are selected with parameter P15.
Fixed Reserve
When the fixed reserve is selected, the control
multiplies the maximum system capacity by the
percent value set in parameter P16 and uses the result
as a reserve.
Water Usage Pattern
Theotherreserveoptionallowsthecontroltoadjustthe
reserve based upon the historical water usage pattern
of the system. The control keeps track of the water
usage for each day of the week and uses that day’s
average usage multiplied by 1.2 as the reserve for that
day. Every day at the Time of Backwash, the control
recalculates the day’s average water usage. If less than
10% of a day’s average water usage is used, the
control will not change the day’s average. If more than
twice the day’s average is used, the control uses the
actual usage in the reserve calculation.
Since a new installation has no history of water usage,
the control multiplies the percent of capacity value set
in parameter P16 by the total system capacity to
determine starting average for each day of the week.
The factory set default value for P16 is 30 which means
that 30% of the total system capacity is used for the
starting average for each day.
Program parameter P15 is also used to select whether
the control waits until the Time of Backwash set in
parameter P2 to start a backwash, or if the control
should begin a backwash immediately when the
capacity remaining is less than the reserve.

Water Meter Maintenance
Note: A water meter is used only with the 960F control.
If you are using the 440i or 940F control, this section
does not pertain to your conditioner.
The metering device used with the 960 demand
controls may require simple maintenance. In rare
instances, the turbine wheel of the water meter can
collect small particles of oxidized iron, eventually
preventing the wheel from turning.
1. Shut off the water supply or put the bypass valve(s)
into the bypass position.
2. Relieve pressure by opening the Backwash Drain
Valve (the seventh back from the control) with a
screwdriver (Figure 14).
3. Loosen and remove the pipe/tube adapters or
1265 bypass from the inlet and outlet of the valve
body.
4. Using a needle-nose pliers, remove the turbine
from the outlet housing. Grasp one of the four
vanes of the outer gland and pull straight out to
remove turbine assembly from the outlet of the
valve (Figure 18).
5. Carefully remove the turbine wheel from the
housing. Use a toothbrush to lightly scrub the iron
off the magnet. Iron buildup on the surfaces can be
removed by soaking the wheel in a mild sodium
hydrosulfite (such as RoVer*) solution for a few
minutes. Flush thoroughly with water.
6. Carefully reinstall the turbine wheel into the turbine
cagehousing. Make surethat the shaft of thewheel
seats intothe bearing of the cage. Reassemble the
turbine cage and check that the wheel rotates
freely.
7. Reinstall the turbine cage into the outlet of the
valve.
8. Reinstall the pipe/tube adapters or 1265bypass to
the inlet and outlet of the valve.
9. Turn on the water supply or put the bypass valve(s)
into the service position and purge theair out of the
system.
To check for proper meter operation, open a
downstream faucet and observe the water flow
indication on the control display.
