INTRODUCTION
General Warnings
The control valve, fittings and, or bypass are designed to
accommodate minor plumbing misalignments but are not
designed to support the weight of a system or the
plumbing.
Do not use Vaseline, oils, other hydrocarbon lubricants or
spray silicone anywhere. A silicon lubricant may be used on
black o-rings but is not necessary. Avoid any type of lubri-
cants, including silicone, on red or clear lip seals.
The nuts and caps are designed to be unscrewed or tightened by hand or with the special plastic wrench. If necessary
a pliers can be used to unscrew the nut or cap. Do not use
a pipe wrench to tighten or loosen nuts or caps. Do not place
screwdriver in slots on caps and/or tap with a hammer.
Do not use pipe dope or other sealants on threads, Teflon
tape must be used on the threads of the 1" NPT elbow or the
1/4" NPT connection and on the threads for the drain line
connection. Teflon tape is not necessary on the nut connection or caps because of o-ring seals.
After completing any valve maintenance involving the drive
assembly or the drive cap assembly and pistons, press the
NEXT and REGEN buttons for 3 seconds or unplug power
source jack from the printed circuit board (black wire) and
plug back in. This resets the electronics
and establishes the service piston positions. The display
should flash all wording, then flash the software version (e.g.
154) and then reset the valve to the service position.
All plumbing should be done in accordance with local plumbing codes. The pipe size for the drain line should be a minimum of 1/2". Backwash flow rates in excess of 7 gpm or
length in excess of 20' require 3/4" drain line.
Solder joints near the drain must be done prior to connecting the drain line flow control fitting. Leave at least 6"
between the drain line control fitting and solder joints when
soldering pipes that are connected on the drain line control
fitting. Failure to do this could cause interior damage to the
drain line flow control fitting.
When assembling the installation fittings package (inlet and
outlet), connect the fitting, to the plumbing system first and
then attach the nut, split ring and o-ring. Heat from soldering
or solvent cements may damage the nut, split ring or o-ring.
Solder joints should be cool and solvent cements should be
set before installing the nut, split ring, and o-ring. Avoid getting primer and solvent cement on any part of the o-rings,
split rings, bypass valve or control valve.
Plug into an electrical outlet. Note: All electrical connections
must be connected according to local codes. (Be certain the
outlet is uninterrupted.)
Install grounding strap on metal pipes.
Softening of water by the exchange process involves the
exchange or substitution of the hardness minerals, chiefly calcium and magnesium, for sodium minerals.The exchange is made
possible because the minerals are ionic in nature (often called
ionized impurities) which means they have an electrical charge.
The ion exchange process is based on the fact that like charges
repel one another, and unlike charges attract.
Calcium and magnesium ions in water are actually dissolved
rock. They have been dissolved by water, the “universal solvent”,
as it trickles down through strata of rock and soil it dissolves calcium and magnesium deposits. This dissolved rock eventually
finds its way into an underground aquifer and when water from
the aquifer is pumped to the surface, it contains the dissolve
hardness minerals of calcium and magnesium and is said to be
hard water.
An ion exchange softener exchanges the hardness minerals, calcium, and magnesium, for sodium, from the softener resin.
Sodium is less objectionable because it does not build up on surfaces as scale deposits.
All three minerals are positively charged ions called cations. The
exchange takes place by passing water containing hardness
minerals over a man-made ion exchange resin contained in a
suitable tank. The resin, polystyrene divinyl benzene in mostmodern softeners, consist of millions of tiny plastic beads, all of
which contain many negatively charged exchange sites to attract
the positive cations. When the resin is in the regenerated state
these negatively charged exchange sites hold positively charged
sodium cations.
As the calcium and magnesium contact the resin beads in their
travel through the resin tank, they displace the sodium ions from
the exchange sites. During the ion exchange process, relatively
small amounts of other strongly charged cations such as iron
and manganese are also removed along with the calcium and
magnesium.
Ion exchange is possible for two reasons: (1) All cations do not
have the same strength of positive charge and (2) the resin
prefers the stronger charged cations calcium and magnesium
than it does the weaker sodium cations.
The exchanged sodium cations pass downward through the
resin “bed” and out the softener outlet, thus, the softener delivers
“soft”water.
Eventually, all of the resin exchange sites are occupied by calcium and magnesium and no further exchange can take place.The
resin is said to be exhausted and must be regenerated.
The softener resin is regenerated with a dilute brine solution of
sodium chloride (common salt) and water. During regeneration
the flow of service water from the softener is first stopped. Brine
is drawn from the brine tank mixing with a separate stream of
water. The brine solution flows through the resin, contacting the
resin beads loaded with calcium and magnesium ions. Even
though the calcium and magnesium are more strongly charged
than the sodium, the concentrated brine solution contains
literally billions of weaker charged sodium ions which have the
power to displace the smaller number of calcium and magnesium
ions. When the calcium and magnesium ions are displaced, the
positive sodium ions are attracted to the negative exchange sites
is said to be regenerated and ready for the next softening cycle.

CONTROL VALVE FUNCTIONS
This glass filled Noryl fully automatic control valve is designed
as the primary control center to direct and regulate all cycles of
a water softener. The control valve can be set to regenerate on
demand (consumption of a predetermined amount of water)
and/or as a time clock (passage of a particular number of days).
The control valve is compatible with a variety of regenerants
andresin cleaners. The control valve is capable of routing the
flow, of water in the necessary paths to regenerate or backwash
water treatment systems. The injector regulates the flow of brine
or other regenerants. The control valve regulates the flow rates
for backwashing rinsing and the replenishing of treated water into
a regenerant tank.
The control valve is designed to deliver high service (27 gpm @
15 psig) and backwash (27 gpm @ 25 psig) flow rates when the
bypass has straight fittings. The control valve uses no traditional
fasteners (e.g. screws), instead clips, threaded caps and nuts
and snap type latches are used. Caps and nuts only need to be
firmly hand tightened because radial seals are used. Tools
required to service the valve include one small blade screwdriver, one large blade screwdriver, pliers and a pair of hands. A
plastic wrench is available which eliminates the need for screwdrivers and pliers. Disassembly for servicing takes much less
time than comparable products currently on the market.
The transformer power pack comes with a 15-foot power cord
and is designed for use with the control valve. The transformer
power pack is for dry location use only.The control valve remembers all settings for two hours if the power goes out. After two
hours the only item that needs to be reset is the time of day, all
other values are permanently stored in the nonvolatile memory.
The control valve does not need batteries.
When the control valve is used as a down flow softener, two
backwashes always occur. The softener will start regenerant
prefill before regeneration, the prefill starts two hours before the
regeneration time set. During the 2-hour period in which the brine
is being made, treated (softened) water is still available. For
example:regeneration time = 2:00 am, prefill option selected,
downflow softener. Fill occurs at 12:00 a.m., start of backwash
cycle occurs at 2:00 a.m.
The softener will adjust the backwash and rinse cycles automatically when the salt dosage is changed . Backwashes can
be set to be NORMAL or LONGER. The option selected will
apply to all backwashes. Tables 4 and 5 show the length of the
cycles when the valve is set up as a softener.
REGENERATION STEPS AND PURPOSE:
Brine fill – Brine tank is filled to dissolve salt for next
regeneration.
Backwash – Flow through the resin bed is reversed.
Water flows upward expanding and agitating the resin bed.
Brine in – Brine is educted from the brine tank and passes through the resin bed in a downward flow, thus removing calcium and magnesium that has accumulated on the
resin beads and is flush to drain.
Backwash – A second backwash is performed
Rinse – The resin is now flushed downward at a set
flow rate. This resettles the bed and rinses out any
remaining brine left in the resin bed.
Service – Softener goes back into service and ready to
soften water.

Control Valve Function and Cycles of Operation
INSTALLATION
Conduct a visual check of all equipment for any damage that
may have occurred during shipment.
Note: If there is obvious damage to any equipment, it should
be noted on the carrier’s Bill Of Lading. Open and inspect the
contents of all closed crates, cartons, etc. and inspect for concealed damage. The manufacturer is not liable for any damage during transit.
Position the equipment in its proper location, setting on a flat
surface. Level equipment as required. Equipment out of
plumb can exhibit poor flow characteristics, which will affect
the performance of the system.
Note: Units are shipped with media (resin & gravel), distributions tube, and control valve installed. Double-check the valve
installation on the tank. Tighten if necessary.
Unit should be positioned with the valve control facing forward.
Check the main line water pressure.The softener is designed
for a minimum of 20 psi and a maximum of 125 psi working
pressure. If the line pressure exceeds this limit, a pressurereducing valve should be installed.
Maximum allowable water temperature is 40°F (4°C) – 110°F
(38°C). A 120vac 60 cycle electrical source must be available
for operation of the controller.
Connect raw water supply line to the inlet valve connection.
Connect treated water outlet to service line. It is suggested that the
pipe size be equal or one size larger than the valve connection.
Note: Softener to be located at least 10 feet away from hot
waterheater to protect against hot water back-up.
Warning: When piping with copper, solder all piping as subassemblies before installing. Internal damage can result from
the high heat of the torch.
It is recommended that manual isolating valves be installed
on the inlet and outlet piping along with a system bypass
valve. This will isolate the unit when service is required.
Run drain line to a sump, drain trench, or other open drain.
Open drains are required for taking samples and allowing a
visual check. Avoid overhead pipe runs to drain facility, as
undue backpressure will affect the operation of injectors.
Note: All piping is to meet your local and state code. AVOID
CROSS CONNECTIONS!
Position brine tank approximately 6" from the softener tank on
a smooth surface.
Connect the brine air check assembly in the salt/brine tank to
the brine suction (eductor) connection. If brine tank is located
more than 6 feet from softener tank, use one size larger tubing. Tubing 5/8" should be installed from the brine tank overflow to drain. This is a gravity drain designed to divert brine to
the drain in the event of a malfunction, which would cause
overflow of the brine tank.
Be sure inlet/outlet isolating valves are closed and bypass
valve is open.
Installation Preview
STEP 1: Select Location
Locate main water supply for all faucets and appliances in
home (if possible outside faucets should be separate so not
to waste soft water).
Select location that is easily accessible to 110vac power. A
15-foot power cord is provided.
You will also need a drain close by for disposal of regenerated wastewater.
Leave enough room between walls so you can easily add salt
when needed.
Locate the water softener at least 10 feet away from the hot
water heater so that hot water does not backup and damage
the softener.
Make sure water softener is in a level spot. You may be
required to put the softener on a platform, such as a piece of
3/4” plywood and shimmed to become level.
Make sure softener is behind any other water conditioning
systems installed in series, except a system that is for taste
and odor or a Reverse Osmosis system.
Select a location were water damage will be least likely to
occur if a leak should develop.
If installing the softener in an outside location make sure
to protect from the elements, such as rain, sunlight, and
contamination.
STEP 2: Install a bypass
Note: Always install a bypass, either a 3-way valve system
or the standard bypass for the valve you have.This will allow
you to shut off the water supply to the softener, but still have
water in the house if the softener is in need of repair.
After a location has been determine install bypass onto the
control valve. (Figures 1 and 3 show standard bypass on
valve.) (Figures 2 and 4 show 3-way by pass plumbing.)
Note: If installing a 3-way bypass valve, do so now.
Close main water supply valve, at the well or at the water meter.
Shut off electrical or fuel supply to the water heater.
Open all faucets to drain pipes.
Note: If installing standard bypass, move to step 3.
The bypass (provided) easily connects to the valve body
using nuts that only require hand tightening. The split ring
retainer design holds the nut on and allows load to be spread
over the entire nut surface area reducing the chance for leakage. Make certain the nut is placed on first, then the split
retainer ring, followed by the o-ring to make the seal. A silicon
lubricant may be used on the black o-ring seals. This design
allows for an approximate 2-degree misalignment of the
plumbing. This design will allow for minor plumbing misalignments, but should never handle the weight of the plumbing
system.

When installing sweat copper follow state and
federal codes by using a lead free solder and
flux. Use a joint compound to seal threaded pipe.
Some homes use the cold water pipes for an electrical ground (metal only). Whenfinished with
plumbing, a ground wire should bre connected
to the copper pipes to complete the ground curcuit. Use two clamps and #4 copper wire for this.

INSTALLATION
STEP 4: Move brine
tank next to softener
and connect brine
draw line to value.
With brine tank next to the softener tank connect the brine
drawline to valve body.
Control valves that use a regenerant, come equipped with a
3/8" refill flow control assembly.
To complete the regenerant line connections orientate the
outlet in the desired direction and push the plastic insert into
the poly tube. Push the poly tube into the nut. Do not use
pipe dope or other sealant on threads. The threads for the
compression nut do not need Teflon tape. Tighten the nut
securely to create a pressure tight connection. A pliers or
crescent wrench may be used to tighten or unscrew the nut.
The nut, gripper and retainer sleeve is a 3-piece assembly
that can come apart if removed from the elbow body.
Parts
must be reassembled exactly as shown in refill flow control assembly drawing to function properly. If the nut is
completely removed from the body, slip the nut, plastic
gripper and retainer sleeve on to the tube then tighten on
to the fitting. Complete the connection by installing the
loose end of the tubing to the brine valve in the salt tank.
STEP 3:
Move softener
into place
Make sure floor is level.
Install shims if needed.
Measure, cut, and install
pipe and fittings to the
bypass valve (dry fit only
to make sure you have a
proper fit) inlet and outlet side. Be sure hard
water is supplied to the
inlet side. Trace pipe to
be sure.
The installation fittings connect to the control valve or the
bypass valve using nuts that only require hand tightening.
Hand tighten nut connections between control valve and
installation fittings, control valve and bypass valve, and
bypass valve and installation fittings allow for easy serviceability. Do not use a pipe wrench to tighten nuts on
installation fittings. Hand tighten only.
Split ring retainer design holds the nut on and allows load
to be spread over the entire nut surface area reducing the
chance for leakage.The split ring design, incorporated into
the installation fittings allows approximately 2 degrees off
axis alignment to the plumbing system. The installation fittings are designed to accommodate minor plumbing misalignments but are not designed to support the weight of a
system or the plumbing.
When assembling the installation-fitting package, connect
the fitting to the plumbing system first and then attach the
nut, split ring and o-ring. Heat from soldering or solvent
cements may damage the nut, split ring, or o-ring. Solder
joints should be cool and solvent cements should be set
before installing the nut, split ring, and o-ring. Avoid getting primer and solvent cement on any part of the orings, split rings, and bypass valve or control valve.
Solvent cements and primers should be used in accordance with the manufacturer’s instructions.
Slip the nut onto the fitting first, then the split ring second
and the o-ring last. Hand tighten the nut. If the fitting is
leaking tightening the nut will not stop the leak. Remove
the nut, remove the fitting, and check for damage or misalignment of the o-ring.
Do not use pipe dope or other sealant on threads. Teflon
tapemust be used on the threads of the 1" NPT elbow
and the 1/4" NPT connection and on the threads for the
drain line connection. Teflon tape is not necessary on the
nut connection or caps because of o-ring seals.
Note: When assembling the installation fitting
package, connect the fitting to the plumbing
system first and then attach the nut, split ring
and o-ring. Heat from soldering or solvent
cements may damage the nut, split ring, and
o-ring. Make sure solder joints are cool
before assemble is started.

INSTALLATION
STEP 5: Connect the Drain Line
If the drain line is a 5/8" flexible poly tube, slide the nut onto
the poly tube, then place the poly tube insert into the end of
the poly tube and tighten the nut on to the 3/4" drain line fitting. The nut is only designed for use with flexible poly tube.
Use other nuts if attaching different materials. Run line to a
drain. Making sure you have a 1 1/2" airgap. You may use a
floor drain, standpipe or any open type drain (see Fig 10).
Do not use Vaseline, oils, or other unacceptable lubricants on
o-rings. A silicon lubricant may be used on the black o-ring.
Use a pliers or crescent wrench to tighten or unscrew the nut.
Do not use a pipe wrench to tighten or loosen nut. Do not use
pipe dope or other sealant on threads. Use Teflon tape on the
threads of the drain line control fitting when installing 3/4"
NPT or 1" straight fitting.

STEP 5: Start-up
Place the bypass valve in the “bypass” position or mode
(see figures 12-14 below.)
Open the main water supply valve.
Open a couple of cold water faucets that are to be conditioned
and let run until air is expelled and pipes are full.
Open the outlet valve of the bypass.
Close the bypass valve.
Press and hold the regen button on the keypad for 3 seconds.
This will put the valve in manual mode. Now press the Regen
button twice.This will put the system in backwash. Slowly open the
inlet valve. (Open the valve a little at a time, pausing several times
to allow the unit to fill slowly and expel air.) When the tank has filled
and a steady flow to the drain is achieved, let the system run until
clear water can be seen coming from the drain line. When water is
clear press the regen button 4 times. This will take the valve back
to service position. Open several cold water and hot water faucets
and let run until hot water heater is full and cold water faucets have
expelled trapped air. Turn electrical power back on or re-light the
hot water heater. Now continue with control valve setup.
