Section LI Product Summary
You have just acquired a USF Consumer Products commercial softening system. Your system may be
equipped with one of the following control systems.
Calendar Clock The calendar clock softener can be a single or multiple unit softener. The single unit
comes with standard with delayed regeneration typically 2:00 am and has a hard water bypass piston. The
duplex or more units also comes standard with delayed regeneration and has a no hard water bypass
pistons. These units are not electrically interlocked so the regeneration time must be staggered so more
than one unit does not regenerate at a time.
-
System 4-The system 4 is a single meter initiated unit. It comes standard with delayed regeneration
typically 2:00 am and has a hard water bypass piston.
System 5-The system 5 is a duplex meter initiated system with all units in parallel service. Each unit has
its own meter and brine tank. Regeneration is immediately at end of service run and an electrical interlock
prevents regeneration of a unit while another is in regeneration. No hard water bypass pistons are standard.
System 6- The system 6 is a duplex meter initiated system with all units in parallel service. Each unit has
its own brine tank but shares a common meter on the outlet header. Regeneration is immediately at end of
service run and is series regeneration. No hard water bypass pistons are standard.
System 7 The system 7 is a duplex alternating service/stand-by system with one unit on line and the
other in regeneration or stand-by. The system comes standard with one brine tank and one meter on the
common outlet header. Hard water bypass is prevented with no hard water bypass pistons 2900 or 3900
valve and automatic diaphragm isolation valves on all other types.
-
System 8-The system 8 is a single sensor initiated unit. It comes standard with delayed regeneration
typically 2:00 am and has a hard water bypass piston.
System 9-The system 9 is a duplex sensor initiated system with all units in parallel service. Each unit has
its own brine tank. Regeneration is immediately at end of service run and an electrical interlock prevents
regeneration of a unit while another is in regeneration. No hard water bypass pistons are standard.

Section 3.
Inspection
3.1 General
Check the product summary to determine what options you have received.
If you have not received the items that are required for assembly of the softener, please contact your supplier.
Inspect the equipment, including internal distribution, for any visible shipping damage. If damaged, noti’ the
transportation company and request a damage inspection. Damage to cartons should also be noted.
Read manual thoroughly before proceeding with installation.
Handle softener unit with care. Damage can result if dropped or set on sharp, uneven projections on the floor.
Each softener you have received consists of the following items:
*
Control valves.
includes assembled valve, backwash and brine line flow controls
*
Fiberglass tank, complete with internal distribution
*
Softener media and gravel support bed
*
Brine tank & accessories, ie brine tank, tubing, etc. Note: all standard systems except system 7 have one brine
tank per softener.
-
-
-

Other items that may accompany your softener are:
*
Volumetric meter, meter initiated units only
*
Systemax 2000 Programmable Controller.
comes with interconnecting cables, and operation manual.
*
Treated water regeneration kit.
-
Section 4.
Installation
4.1 Tank Positioning
*
Position the tanks as shown on the installation drawing, see Appendix C for drawing
Note: ‘The tanks should be located on a level support pad. ic/il, adequate access space on all sides, ‘all
sjstenis must be u/thin 3 feet of one another for the interconnect cable to properly attach.
*
*
tt,iits in
chip/es and/or triplex
Check hub and laterals in the tank for any damage that may have occurred during transport. This is critical because if
the distribution is broken, the media will go out into the service lines.
Thread the control valve snugly into the tank using silicone grease # 13691 not included on 0-rings, and adjust
softener position until the desired orientation is achieved.
ivote: Do flat niove tank after this is completed. because once the softener media is installed, ii tel/I be t’ei’ difficult to

and danicege
4,2 Media Installation
*
*
*
*
*
Remove the valve from the mineral tank.
Temporarily plug the open end of the riser tube to ensure that no resin or gravel falls down into the distribution.
Fill mineral tank one quarter full of water to protect distribution during gravel installation.
Slowly and carefully add the gravel support bed and the softener media as outlined in Section 5. Media
Specifications. leveling each layer as it is placed into the tank.
Unplug the riser tube, careflully position the valve over it and turn valve into threads in fiberglass tank, tightening
securely into tank.
Note: Ensure that the internal Q.ring iii the vah’e fits securely over the riser tube. Silicone grease or othet’foacl grade lubricant. ittay be applied
to the 0-ring to ease installation of the riser tube.
*
*
The softener is now charged with softening resin,
It is recommended that the softener tank now be completely filled with water SLOWLY to soak the resin for
approximately 6 hours before startup. This will allow the media to absorb water as velI as help displace any trapped
air. and this will reduce the chance of backvashing resin out during startup.
Feb99
4.3 Piping
*
*
*
Install the piping conforming to federal, provincial and local codes. Unions andlor flanges are recommended and
isolation and by-pass valves should also be installed. Inlet and outlet piping should allow for slight expansion and
contraction of the fiberglass tank during operation under system pressure. For proper system operation and startup,
and to monitor the softener’s removal capacity and efficiency, sample points and pressure gauges must be installed
on each unit immediately before on the inlet piping and after on the outlet piping each softener. See Fig. 4.1 for a
typical installation.
The drain line should be as short as possible and must be piped to an open drain. Access to the drain and an air gap
are necessary for visual inspection and testing of drain water. The floor drain must be sized to carry the maximum
listed flow to drain. See section 2 for flowrates It is recommended that the drain pipe size should be at least the
same size of pipe or larger as the inlet and outlet piping. See section 2.4
Install the backwash flow control in the drain line piping. The arrow stamped on the side of the control indicates the
direction of flow to drain. The backwash flow rate is controlled by a flow control that is factory set, and does not
require adjustment on site. This flowrate may be checked by timing and measuring the flow through to the drain.
If the treated water exiting the system is flowing into an open reservoir, it is recommended that a loop in the piping
be installed in the system outlet to prevent the units from draining down, which can lead to operational problems.
The loop must extend above the top of the mineral tanks with a vacuum breaker at the high point of the loop, and
then drops into the reservoir. Include an air gap to help prevent siphoning._ The system will have the best service
performance if there is some backpressure on the system eg. 30 psi. This could be achieved by partially closing a
system outlet valve or putting on flow controllers into the outlet piping not included.
Any piping before and after the units must be properly supported, to prevent any stress on the unit by the piping.

4.3.1 Optional Treated Water Regeneration Installation
The treated water regeneration kit allows a clean,
water source to be used as the regeneration water
supply which results in a more efficient
regeneration.
* The treated water regeneration kit consists of two,
pneumatically or hydraulically actuated diaphragm
valves per unit installed in the piping, as shown
on the drawing shown:

An SVO, or service valve operator has three ports, drain, pressure, and control valve, The diagram
below illustrates the location of each of these ports on the SVO. To ensure proper operation of the
diaphragm valves, the supply pressure must be a continuous water pressure source and the pressure
must be equal to the highest pressure the system will see. If this is not possible, air pressure may also
be used with the air pressure set to the highest water pressure the system will see.

Media Specifications
Each softener size is based upon the volume of softening resin that is in the mineral tank. Each cubic
foot of our standard softening resin is FDA approved for potable water and has a generic capacity of
30,000 grains @15 lbs saltlftt. This number is only approximate, and does vary depending upon the
influent water quality. For example, an FAF 120 softener has 120,000 grains of generic capacity, i.e.. four
cubic feet of softening resin in the mineral tank. Note: Softeners are factory set for 10 lbs salt/ft

Recommended Start Up Procedure
a.
7.1 Softener Start-Up
NOTE: It is important to follow the startup instructions as improper start up may
result in unsatisfactory softener operation or possibly damage the softener.
*

3.
4.
5.
6.

8.
Check all system piping ensuring that it is correct and all connections are complete, see installation
drawing fig. 4.1. and ensure the drain line has an air gap. Ensure that all of the manual isolation and
by-pass valves are closed prior to start up. Check all electrical connections and ensure that they are
correct and complete fig 4.8 or 4.9.
With the brine tank empty, add clean water approx. 3,5 US gallons per cubic foot of resin Section
5.2.3 to the brine tank ensuring the water level is at least 2" above the grid plate. Add at least 15 lbs
of salt for each cubic foot of resin to the brine tank and allow the brine tank to sit for a couple of hours
to make a good brine solution.
Plug in the control valve, and manually advance the valve out of the home position. for ET &
Systemax, see their respective manuals On all systems except system 7, this is done by the timer on
the valve, On system 7 units, the regeneration is initiated by the remote meter which electrically
starts the appropriate valve timer .This is done by removing the dust cover, and swinging the cycle
timer open, in order to expose the program wheel located inside, mechanical timers only The meter
cable may have to be temporarily disconnected. Turn the program wheel out of the home position,
until the home switch comes out of the notch in the program wheel. Once the softener is in the
backwash position, where the position switch rides up on to the first set of pins, refer to section 8 for
position confirmation, unplug the softener.
Slowly partially open the inlet isolation valve, and allow the softener to slowly fill with water. When
the tank is full, water begins to run out through the drain. If the zen/f is filled too quickly, the media
could be bloivn ott!, as well as possible damage the unit. When full, close the inlet valve.
Allow the unit to stand for 1-2 hours once the tank is full to saturate the media bed.
Plug the unit back into the power supply, and slowly open the inlet isolation valve all of the way, and
allow the unit to automatically complete its regeneration cycle. During the backwash cycle, constantly
check the drain water for resin to ensure nothing other than fines are being backwashed out. During
the brine draw cycle, ensure the unit is drawing brine out of the brine tank. The brine should be drawn
out in 15 to 30 minutes depending upon injector size and line pressure. Also check the brine tank refill
cycle to ensure the water level returns to above the grid plate and there is no water flowing to the brine
tank once the regeneration cycle is complete. Ensure that an adequate supply of salt is available, and
that enough salt is situated in the brine tank. For example, if an FAF 120 softener was to be
regenerated at 10 lbs/ft3, this equates into 40 lbs of salt required for one regeneration cycle. Thus at
least 40 lbs is required in the brine tank for a single regeneration of this softener. If the meter cable
was disconnected, ensure it is reconnected.
Once the start-up is complete, the valve control system must be configured. To configure a calendar
clock, sensor or meter initiated softener, please refer to section 9. To configure either the ET Digital
Timer, or the Systemax 2000 Controller, please refer to their service manuals.
Upon completion of the steps above, the softener outlet isolation valves are slowly opened, and the
bypass valve can then be closed. The softener is now ready for normal service operation.. It is
recommended that both the raw water and treated water be tested to confirm the unit is working
properly.

Section 8.
Softener Operation 2900 Valve
8,1 Operating Conditions
For correct operation of the softener system, the minimum water pressure required is 30 psig, 206
kPa, in order for valve to operate effectively.
Caution: Water Pressure is not to exceed 100 psis. 690 kPa. water temperature is not to exceed 100 F. 38 C, and the unit
can not be subjected to freezing conditions without taking special precautions.
The manual bypass valve, by others, must always be closed and the manual inlet and outlet isolation
valves, by others, open except during maintenance of the equipment.
8.2 Cycle Operation
The current position of the control valve can be confimed by opening the control valve cover, and
looking at the cycle cam position. Each cycle is completed at specific locations during the cam’s rotation.

Service
During service, water is directed into the top of the tank by the control valve and flows downward
through the softener media, into the distribution, and out to service. As the water flows through the
softener media, the hardness calcium and magnesium dissolved io the water is ionically exchanged with
either sodium or potassium present in the softening resin. During service, the drive gear holds the drive
link completely horizontal, with the piston withdrawn to its maximum length.

As the duration of the service run increases, the softening resin slowly depletes, losing its ion
exchange capacity, until the softening resin can no longer remove the hardness calcium and magnesium.
It is at this time that regeneration of the softener is required, in order to replenish the bed’s softening
capacity. During regeneration the hardness calcium and magnesium that accumulated during the previous
service run are replaced on the resin by sodium or potassium. A brine solution rinsed down through the
bed is the source of the replenishing sodium or potassium.

Backwash
The regeneration procedure is performed automatically by the softener after the cycle controller has
started. Each regeneration cycle consists of four steps; backwash, brine draw/slow rinse, fast rinse, and
refill.
During backwash, water is directed upwards through the filter and out to drain. This loosens
the softener bed, allowing the brine solution to rinse through the resin more easily during the next cycle.
The backwash cycle has been factory preset to take place for 10 minutes.
The drive gear holds the drive link completely horizontal, 1800 from the service position, with the
piston rod fully inserted into the valve body.

Position 3. Brine Draw
During the brine draw position, water flows through the injector, drawing in the brine solution. This
solution then flows down through the bed, and out the drain. The brine draw cycle ends when the brine
tank is empty, and the air check in the brine tank closes, stopping the flow of concentrated brine. Water
continues to flow through the injector, and down through the bed, but no brine is drawn in. This is referred
to as the slow rinse cycle.
When in the brine draw/slow rinse position, the drive link is rotated approximately 40 from the
backwash position, until the drive gear stops with the drive link connection at the bottom of the drive gear,
with the drive link at approximately 400 angle from the horizontal.

Brine Tank Refill
Eosition 5
Upon the fast rinse cycle ending, the softener advances into what is essentially service, with the
exception that a portion of the softened water is diverted backwards through the injector, and into the brine
tank. This is known as the brine tank refill cycle. The flow into the brine tank is controlled by a flow
control orifice, and is timed in order to measure a calculated volume of water into the brine tank. The brine
tank refill position is very similar to the service posItion, but the drive link stops just short of the
horizontal, To confirm the refill cycle is occurring, simply watch the tubing running from the softener to
the brine tank, and watch the brine tank to ensure that the water level is rising. The water should continue
to flow to the brine tank until the microswitch is depressed by the last two pins on the cycle tinier wheel.

Softener Control
The standard softener controller is a mechanical type controller, which automatically initiates the
backwash sequence by one of three methods: calendar clock, volumetric meter, or sensor.
All systems can be manually initiated by simply moving the manual regeneration knob clockwise. Only a
slight turn is required to start the unit into regeneration. Remote meter initiated units should be manually
initiated ONLY from the remote meter, which is again started by a slight clockwise movement on the
remote meter timer knob.
Other control systems are available, such as the ET digital timer, which can replace the standard
mechanical controller; and the Systemax 2000 Digital Controller, which looks after the operation of up to
three, 3, separate units; including giving visual indication offlowrates, time, and allowing operator
control of the method of initiation. For information on configuring either the ET digital tinier or the
System Max, please consult their service manuals.
For a description of the various systems, see section 1.
9.1 Calendar Clock
With calendar clock initiation, a 12-day repeating timer automatically initiates the regeneration
sequence after a preset number of days during the 12-day cycle. The regeneration sequence is factory
preset to occur at 2:00 AM on the day that the clock initiates regeneration. Once initiated, the cycle timer
operates the control valve, advancing the valve into each position, and holding it there for a specific length
of time. The interval between regenerations can be adjusted to suit each application, depending on the raw
water quality. This time interval is adjustable, with a minimum regeneration sequence interval of one
regeneration per day.

*
Press and hold the red button in to disengage the drive gear.
* Turn the large gear until the actual time of day is opposite the time of day pointer.
*
Release the red button to again engage the drive gear.
Frequency of regeneration:
To set the frequency of regeneration, simply pull out the metal tabs on the skipper wheel on the days that
you wish the filter to regenerate, For example, every 3rd tab has been extended in the illustration above,
indicating that regeneration of that filter will take place every three, 3, days.
9.2 Volumetric Meter
The second method of regeneration initiation is by a volumetric meter, which counts the
volume of water as it passes through the filter during service. The meter is attached to a Fleck model
3210 control timer, by a rotating cable. The control timer has an adjustable volume dial on it, where
the volume of water to pass through the meter between regenerations can be set. As the water flows
through the fiowmeter, the cable rotates, slowly moving the volume dial on the timer towards zero. On
Feb
all standard single units, once the meter reaches zero, the start signal will be delayed until the preset
time. This is why on single units a reserve capacity needs to be calculated into the meter setting. On
all standard duplex units, once the meter reaches zero, it immediately signals the cycle timer to begin
the regeneration sequence provided that the other unit is not already in regeneration., Once signalled,
the cycle timer takes over for the duration of the regeneration cycle, controlling the regeneration
sequence, just as in the calendar clock control method.

Meter Settin2 Procedure
System 4
-Take the number of cubic feet of resin in the tank and multiply by 27,000 grains per cubic foot for a 10
lbs salt setting.
-Divide this number by the compensated grains of hardness in the water. This gives you the total number
of gallons the softener can treat before regeneration is required. REMEMBER that I pan of iron is equal to
4 grains of hardness and 1 part of manganese is equal to Spans of hardness. For commercial units, the
combined ppm maximum for iron + 2x manganese is ONE.
-Since system 4 is delayed regeneration, a reserve typically one-day must be built into the meter setting.
-Typically for a three-day sizing, the reserve is 1/3 of the bed so take the total number of gallons and divide
by three. This is what you set the meter for.
-For a two day sized unit, take the total number of gallons and divide by two. This is what you set the meter
for
System 5 or 7
-Take the number of cubic feet of resin in ONE tank and multiply by 27,000 grains per cubic foot.
-Divide this number by the compensated grains of hardness in the water. This gives you the total number
of gallons the softener can treat before regeneration is required. REMEMBER that 1 pan of iron is equal to
4 grains of hardness and I part of manganese is equal to 8 parts of hardness. For commercial units, the
combined ppm maximum for iron – 2x manganese is ONE.
-Since system 5 & 7 is immediate regeneration, a reserve is not normally required.
System 6
-Take the number of cubic feet of resin in BOTH tanks and multiply by 27,000 grains per cubic foot.
-Divide this number by the compensated grains of hardness in the water. This gives you the total number
of gallons the softener can treat before regeneration is required. REMEMBER that I pan of iron is equal to
Fcb
4 grains of hardness and part of manganese is equal to 8 parts of hardness. For commercial units, the
combined ppm maximum for iron + 2x manganese is ONE.
-Since system 6 is immediate regeneration, a is not normally required, but due to the fact that typically you
get more water through one unit than the other, you may want to adjust the gallonage setting down to
compensate for this factor.
9.3 Sensor
The final method of initiation is by sensor. A sensor located in the resin bed combined with the
circuit on the valve monitors the condition of the bed and when it is depleted, will initiate a regeneration.
On single units, the start signal will be delayed until the preset time. On all standard duplex units, once the
unit requires regeneration, it immediately signals the cycle tinier to begin the regeneration sequence
provided that the other unit is not already in regeneration..
9.4 Regeneration C’ycle Timer mectianicaD
The cycle timer controls the operations of the valve during the regeneration sequence by
incoporating a series of switches ,which are opened and closed in a specific order to control the
movement of the valve drive motor at certain times. The cycle timer rotating a program wheel
accomplishes this. In this program wheel, there are holes spaced so that each hole takes two minutes to
pass by. By inserting pins into these holes, and having the switches depressed by these pins as the
program wheel rotates, the switches can be depressed in a specific order, The regeneration cycle timer
is illustrated below. Note: you can tell if the motor is running by looking at the "viewport" located on
the motor.

Figure 9.3 Regeneration Cycle Tinier Rear View
The various typical standard softener control tinier uses only the home, inside, and middle
switches, with the outside switch being used only in specific custom applications. When certain
switches in the control valve are closed simultaneously, the timer allows the valve drive motor to
rotate, moving the piston to certain positions during the backwash sequence.
9.5 Regeneration Program
The regeneration cycle program on your filter has been factory pre-set. Typical cycle times are 10
minutes backwash., varying brine draw and slow rinse times dependent upon the unit, ]0 minutes rinse,
and varying brine tank refill times dependent upon the unit. It should be noted however, that these cycle
times may be lengthened or shortened to suit local conditions.
The pins on the program wheel determine the length of each cycle. Each pin represents two
minutes of cycle time. The length of each cycle is either the number of pins for backwash or fast rinse or
Feb
the number of holes for brine draw/slow rinse and brine tank refill. Please note that, when one set of pins
is moved, it may affect the cycle time of other cycles unless other pins are also adjusted accordingly.
NOTE: Ensure pins for inside switch, if required, do not extend far enough to cause interference with
lower gear.

*
To expose cycle program wheel, grasp the timer
in upper left-hand corner and pull, releasing snap
and swinging timer to the right.
*
To change the regeneration cycle program, the
program wheel must be removed. Grasp the
program wheel and squeeze protruding lugs toward
