The Programming Guide (only “E” Series models) includes step-by-
step procedures for programming the controller for your specic
application.
Many sections of this manual will apply to all models, whereas some
sections may be more series specic. Specic model differences
will be highlighted. Refer to the general arrangement drawings for
examples of typical plumbing congurations and identication of
various components and their connection points.
OPERATIONAL SPECIFICATIONS
For use on cold water only.
Pressure Requirements:
An operating water pressure between 25 and 125 PSI (1.7 - 8.6 bar).
Note: When daytime water pressure exceeds 80 psi (5.5 bar), the
maximum pressure rating of 125 psi (8.6 bar) can be exceeded. A
pressure regulator must be installed on this system or warranty is
voided.
If pressure is greater, install a pressure regulating valve ahead of
the system. If water pressure is lower, install additional equipment
to maintain a 30 PSI (2.1 bar) minimum operating pressure.
Temperature: 40-100ºF (4-38ºC)
1. Clear (non-turbid) water supplies (less than 5 NTU).
CAUTION
The pressure vessels (mineral tanks) provided with the
system should be protected from the following conditions:
a. Vacuum in excess of 5 ½" Hg (17 Pa) below atmospheric – If
negative pressure should ever exceed 5½" Hg (17 Pa), an
adequate vacuum breaker must also be properly installed.
A vacuum breaker should be installed just prior to the inlet
of the control valve. Systems utilizing multiple controls will
require a vacuum breaker for each control valve.
Improper installation of a vacuum breaker when required, may
void the mineral tank warranty.

INSTALLATION
MINERAL TANK and CONTROL VALVE
1. Refer to the general arrangement drawings for typical
installation examples. The installation area should be reasonably
level, smooth, and capable of supporting the operating weight
of the system, including salt. See specication table on page 2
for operating weights. All systems include up to four (4) mineral
tanks and up to four (4) brine tanks. When determining the best
location, consider ease of access for:
a. Control valve adjustments and service
b. Replenishing the brine tank with salt
2. Position the mineral tank(s) in the desired location.
3. CES-3900-450-HWBP and CES-3900E-450-NHWB – 30" (762
mm) diameter mineral tank requires the installation of a ange
adaptor. Lubricate the ange adaptor O-ring with a silicone
based lubricant. Ensure your lubricant is NSF-approved. Position
the O-ring in the grooved area of the ange adaptor. Secure the
ange adaptor with the hardware provided. Tighten the bolts in
the order shown in the illustration below. Tighten to 11 ft-lbs.

4. This step is optional but is strongly recommended for larger
systems, so minimal mineral tank movement will be required
after lling the mineral tank with media. This does not apply to
3900E systems. Lubricate the O-rings on the base of the control
valve (or second tank adaptor) with a silicone based lubricant.
Ensure that your silicone based lubricant is NSF approved.
While centering distributor tube into the center port on the
control valve (or second tank adaptor) base, carefully engage
the threads on the control valve (or second tank adaptor) with
threads on the mineral tank. Screw control valve (or second
tank adaptor) tight. Adjust (rotate) mineral tank so control valve
(or second tank adaptor) faces the desired direction. Without
moving the mineral tank, remove the control valve (or second
tank adaptor.
IMPORTANT: Inspect distributor assembly for damage or missing
parts. Some models have a single point strainer, whereas other
models have a hub and lateral design. Inspect both types prior to
loading media. Ensure the laterals are secure.
5. Cover end of distributor tube with tape, plastic bag, etc. This
prevents media from entering distributor tube.
6. Position the distributor assembly in the tank and verify the
distributor tube height using the appropriate illustration below.
IMPORTANT: 2850E and 9500E Series only – distributor tube
should be ush with tank top, or slightly below. See example
below.
IMPORTANT: 2900 Series only - Distributor tube should be 0.25”
to 0.75” (6.35 mm to 19.05 mm) below top of tank. See example
below.
3900 Series Only – Distributor tube should be ush with tank top
(tank ange), or slightly above [+0.375” max. (+9.25 mm max.)].
See example below.

PENTAIR EVERPURE CES SERIES WATER SOFTENERS INSTALLATION, OPERATION & MAINTENANCE GUIDE FOODSERVICE.PENTAIR.COM • 5
IMPORTANT: CES-2900E-300, Single CES-2900E-300-DP, CES-
2900E-300-TP, and CES-2900-300-QP models only – distributor
assembly (hub) should be positioned as close to the center of the
mineral tank lower head as possible. Some mineral tanks have a
rise in the center of the lower head that may require positioning
the distributor assembly slightly off-center.
CES-3900E models only – Distributor assembly (hub) includes
a centering “cup” that allows the distributor assembly to be
positioned in the center of the tank. If the mineral tank has the
rise in the center of the lower head, position the distributor
assembly on this elevated area.
7. Add water to mineral tank. Fill tank at least 12” (304.8 mm)
above distributor slots and/or lateral arms to prevent damage
to distributor assembly when adding media.
8. Add gravel. See table on page 3 for quantities based on model.
DO NOT allow gravel to reposition the distributor assembly.
Check distributor pipe elevation – do not allow it to rise above
the specied level. Rock tank gently to level gravel if required.
WARNING
Gravel dust can be hazardous. Wear suitable dust
protection equipment. Wet bags to minimize dust.
9. Add resin. Use water to help “uidize” resin and speed-up lling
process. Resin does not require leveling.
10. Rinse top of mineral tank to remove resin from mineral tank
opening area and distributor tube.
11. Remove tape or bag from end of distributor tube.
12. Lubricate O-rings on base of control valve with an NSF-approved
silicone based lubricant.
13. Some models include a top collector that attaches to the base
of control valve. A raised edge on the top collector engages a
groove that is machined into the base of the control valve body.
If one has been provided, install it now. See typical examples below.
Most Models 3900E Series Only
14. Attach control valve to mineral tank.
a. 2850E, 9500E, 2900E Series only – Position upper collector
and/or control valve center port (distributor tube pilot) over
distributor tube, and engage. Rotate control valve clock-wise
while engaging threads. When tightened suciently, gap
between control valve base and mineral tank should be 1/16”
(1.59 mm) or less. Follow these same steps for the second tank
adaptor – 9500E Series only.
b. 3900 Series only – Refer to the illustration below. Lubricate
O-rings with an NSF-approved silicone based lubricant.
Position item 31 and 30 on the tank ange. Position item 24 in
the groove on the control valve base. Position upper collector
and control valve center port (distributor tube pilot) over
distributor tube, and engage. Position item 29 (2) over control
valve ange. Align bolt holes (item 29, 30 and tank ange).
Install fasteners loosely. Rotate control valve if required.
Tighten the bolts in the order shown in the illustration below.
Tighten to 11 ft-lbs.

CONTROL ADJUSTMENTS
DETERMINING CAPACITY
Refer to the specication table (page 2) for exchange capacity of
each model based on salt dosage.
9500E Models only – The operational mode for this group is metered
immediate. In this case, “reserve capacity” is not required.
2900E-DP, 2900E-TP, 2900E-QP, 3900E-300-NHWB, and
3900E-450-NHWB Models only –The operational mode for this
series can vary based on the application. In most cases, the
system will operate in meter immediate mode, (system 14), so the
regeneration occurs as needed, on only one tank at a time.
2850E, 2900E, 3900E-300-HWBP, and 3900E-450-HWBP Models
only – The operational mode for all single softeners is system 4 -
meter delayed. The unit should be programmed to regenerate at an
off-peak time period, such as 2:00 AM. Since this type of system
only examines the need to regenerate once every 24 hours, a
“reserve capacity” is automatically calculated. The NXT2 controller
automatically calculates the reserve capacity and adjusts based on
daily usage.
PROGRAMMING
2850E, 2900E, 2900E-DP, 2900E-TP, 2900E-QP and 3900E
Models only
Refer to the “3200NXT2 Timer Service Manual” and associated
inserts for detailed programming information. A table has been
provided on page 11–12 to assist with programming specic time
intervals based on model and system capacity.
NOTE: 2900E-DP, 2900E-TP, and 2900E-QP Models only –
The programming of each control varies slightly. One control is
programmed as the “LEAD” and the other as the “LAG”.
9500 Models only: See pages 13–14. Master Programming Mode
2850E, 2900E, 2900E-DP, 2900E-TP, 2900E-QP and 3900E Models only

the Extra Cycle button to advance to the next character/digit and
press the Left button to retreat to the previous character/digit.
Proceed through all available characters/digits to advance to the
next value.
4. To reset/clear a value (such as Assistance Name), while on the
value, press and hold the Down and Up buttons simultaneously
for 5 seconds.
5. To exit Master Programming Mode, progress through all
available values or after 5 minutes of inactivity the timer will
exit automatically. To exit master programming without saving
changes, press the Left button until you return to the service
screen.
6. Depending on the current controller programming, certain
values may not be able to be viewed or set.
7. The timer will display local information, not system information.
8. In the event of a regeneration occurring while displaying master
programming, the regeneration step and time remaining will be
displayed. When regeneration has been completed, the display
will return to the main screen.
NOTE: Refer to page 9 of the “Pentair Fleck NXT2 Timer Service Manual” for more detailed information
Min. – Minimum system capacity – based on 6 lbs (2.72 kg) of salt per Ft3(0.028 M3) of resin.
Med. – Medium system capacity – based on 9 lbs (4.1 kg) of salt per Ft3(0.028 M3) of resin.
Max. – Maximum system capacity – based on 15 lbs (6.8 kg) of salt per Ft3(0.028 M3) of resin.
WITH SOFTENER VALVE CONTROL SETTINGS
The following table includes the recommended time durations
for each regeneration step. These values are based on a typical
application. Under certain conditions, these values may require
some adjustment. Refer to the performance specications table
on page 2 to determine the usable capacity of the system, based on
salt dosage. A detailed description of the “Brine Rinse” and “Brine

Start-Up Instructions
Refer to page 15 under Commissioning: Mineral Tank Fill - Operational
Check-Out for more details on testing brine ll, draw and oat test.
1. Slowly open the inlet water valve and allow softener to ll with
water.
2. Press and hold “Extra Cycle” button for 5 seconds until the valve
begins to cycle to BW, allow softener to backwash until air is
expelled from softener and water is running clear and smooth
down the drain.
3. Advance control valve to BD Brine Draw by pressing the
“Extra Cycle” button.
4. Advance control valve to RR Rapid Rinse by pressing the
“Extra Cycle” button.
5. Advance control valve to BF Brine Fill by pressing the “Extra
Cycle” button. Allow softener to ll brine tank to the top of the
air check. Once the water level is above the air check press the
“Extra Cycle” button to return the valve back to service
6. Repeat steps 2-5 for the second tank but for step 5 you would
allow the softener to do a complete brine ll cycle and allow the
unit to return to service on its own

MINERAL TANK FILL – OPERATIONAL CHECK-OUT
1. Manually initiate a regeneration cycle. The control valve will
advance to the backwash position. PARTIALLY open the inlet
isolation valve to allow water to SLOWLY enter the mineral tank
and purge the mineral tank of air.
WARNING
Limit the ow of water into the mineral tank at this
time. Opening the inlet isolation valve too far may expand the
resin bed too greatly and cause resin loss to drain. Observe the
water exiting to drain during this time for the presence of resin.
Throttle inlet isolation valve as required.
2. Once the air is purged, open the inlet valve fully and allow water
to run to drain for ve (5) minutes. Continue to check for the
presence of resin during this time. If resin appears, close inlet
valve and re-check system.
a. Manually advance the control valve to the fast rinse
position. The ow to drain will be the same as in backwash.
Allow the unit to remain in this mode for two (2) minutes. Then
advance valve to next step - brine rell.
WARNING
Observe the water exiting to drain during this time
for the presence of resin. If resin loss is observed, close inlet
isolation valve. Contact technical service –1.800.942.1153.
b. Once in brine rell, no ow will be present at the drain.
Observe the water level in the brine tank - the level will be
ascending.
c. Raise brine oat, ensure there are no leaks and make
sure that the water ow into the brine tank has stopped. Once no
leaks are found, release the brine oat.
d. Fill brine tank with salt.
3. Manually advance the control valve to the brine rinse position.
The ow to drain will be about 1/3 the ow in backwash. Observe
the water level in the brine tank – the level should descend,
and within a few minutes, the air-check should seat. A distinct
change will be heard in the “tone” of the control valve.
WARNING
Observe the water exiting to drain during this time
for the presence of resin. If resin loss is observed, close inlet
isolation valve. Contact technical service – 1.800.942.1153.
Manually advance the control valve to the fast rinse position. This
process can also be used to test the water hardness reduction
of each individual tank in a system. The ow to drain will be the
same as in backwash. Allow the unit to remain in this mode until it
automatically advances to the next step – brine rell.
WARNING
Observe the water exiting to drain during this time
for the presence of resin. If resin loss is observed, close inlet
isolation valve. Contact technical service –1.800.942.1153.
4. Once in brine rell, no ow will be present at the drain. Observe
the water level in the brine tank – the level will be ascending.
5. 2850E, 2900E, 3900E-300-HWBP, and 3900E-450-HWBP
Models only – Allow the control to remain in this step for the
programmed time. The control valve will advance automatically
to service.
9500E Series only see page 14 for additional instructions to
bring softener into service.
2900E-DP, 2900E-TP, 2900E-QP, 3900E-300-NHWB, and
3900E-450-NHWB Models only – Advance the control valve to
the service position. Repeat steps 1–5 on each additional mineral
tank/control valve.
NOTE: The next steps require placing the system “online”. Failure
to follow these steps closely could interrupt the water supply to
the downstream equipment.
VERIFY FLOW METER CONTROL
1. Open manual outlet isolation valve.
2. Close bypass valve.
3. Demand water from a downstream device, or piece of
equipment.
2850E, 9500E, 2900E, 2900E-DP, 2900E-TP, 2900E-QP and
3900E Models only – Observe the ow rate reading on the
display unit of the control valve. If possible, measure the ow
and compare this ow rate to what’s displayed. If the ows are
noticeably different, verify the controller settings – specically
the “Flow Meter Size” setting.
TESTING FOR SOFT WATER
2850E, 9500E, 2900E, 3900E-300-HWBP, and 3900E-450-HWBP
Models only –
1. Open a downstream plumbing xture or soft water sample port
and allow water to run for a few minutes.
2. Collect a sample and test for the presence of hardness – should
be <3 GPG (51.3 mg/L). If hardness is higher, re-check after
several minutes. If a hardness level of <3 GPG (51.3 mg/L) cannot
be attained, re-check bypass valves (fully closed) or refer
to control valve manual troubleshooting section for further
assistance.
3. Close downstream plumbing xture or soft water sample port.
4. System is now in service.
2900E-DP, 2900E-TP, 2900E-QP, 3900E-300-NHWB, and
3900E-450-NHWB Models only –
1. Refer to step 3 of pg. 15 under Commissioning: Mineral Tank Fill -
Operational Check-Out to test for soft water during rapid rinse.
