Control Valve Functions
Control Valve Function and Cycles of Operation
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 and
resin 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 screw-drivers 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
increase with increasing, salt dosage. 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 pass-es 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.

WARNING
General Installation Guidelines
This water conditioner’s control valve conforms to UL/
CE Standards. Generic valves were tested and certified for
compliance as verified by the agency listing. This water
conditioning system is to be used only for potable water.
Inspect the water conditioning system for carrier shortage or
shipping damage before beginning installation.
Operating Perameters:
• Operating ambient temperature: 40° to 110°F (5° to 43°C).
• Operating water temperature: 40° to 110°F (5° to 43°C).
• Operating water pressure range : 25 to 120 psi (1.7 to
8.27bar).
Installation Perameters: All plumbing should be done in
accordance with local plumbing codes.
• Do not use pipe dope or other sealants on threads. Use Teflon
tape on the threaded inlet, outlet and drain fittings. Teflon tape
is not necessary on the nut connection or caps because of
o-ring seals.
• All plastic connections should be hand tightened. Teflon® tape
may be used on connections that do not use an O-ring seal.
Do not use pipe dope type sealants on the valve body. Do not
use pliers or pipe wrenches.
• Observe drain line requirements.
• Keep the media tank in the upright position. Do not turn upside
down or drop. Turning the tank upside down or laying the tank
on its side can cause media to enter the valve.
• The pipe size for the drain line should be a minimum of ½”.
Backwash flow rates in excess of 7 gpm (26.5 lpm) or length in
excess of 20’ (6.1m) require ¾” drain line.
• Do not support the weight of the system on the control valve
fittings, plumbing, or the bypass.

• THIS WATER METER SHOULD NOT BE USED AS THE
PRIMARY MONITORING DEVICE FOR CRITICAL OR
HEALTH EFFECT APPLICATIONS.
• Do not use Vaseline, oils, other hydrocarbon lubricants or spray
silicone anywhere. A silicone lubricant may be used on black
o-rings but is not necessary.
Electrical:
• Use only the power transformer supplied with this water
conditioning system.
• All electrical connections must be completed according to local
codes.
• The power outlet must be grounded.
• All electrical connections must be connected according to local
codes. (Be certain the outlet is uninterrupted.)
• Install grounding strap on metal pipes.
• The power adapter comes with a 15 foot power cord and is
designed for use with the control valve. The power adapter is for
dry location use only. The control valve remembers all settings
until the battery power is depleted if the power goes out.
• After the battery power is depleted, the only item that needs to
be reset is the time of day; other values are permanently stored
in the nonvolatile memory. The control valve battery is not
rechargeable but is replaceable.
• No user serviceable parts are on the PC board, the motor or
the power adapter. The means of disconnection from the main
power supply is by unplugging the power adapter from the
wall.
• Install an appropriate grounding strap across the inlet and
outlet piping of the water conditioning system to ensure that a
proper ground is maintained.
• To disconnect power, unplug the AC adapter from its power
source.
Soldering:
• Use only lead-free solder and flux, as required by federal and
state codes, when installing soldered copper plumbing.
• Use caution when installing soldered metal piping near the
water conditioning system. Heat can adversely affect the
plastic control valve and bypass valve.
• 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 fitting 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.
Control Valve:
• This glass filled Noryl1 (or equivalent) fully automatic control
valve is designed as the primary control center to direct and
regulate all cycles of a water softener or filter.
• 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.
• 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 a
screwdriver in the slots on caps and/or tap with a hammer.
• After completing any valve maintenance involving the drive
assembly or the drive cap assembly and pistons unplug power
source jack from the printed circuit board (black wire) and plug
back in or press and hold NEXT and REGEN buttons for 3

seconds. This resets the electronics and establishes the
service piston position. The display should flash all wording,
then flash the software version and then reset the valve to the
service position.
• The control valve is compatible with a variety of regenerants
and resin 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, when applicable.
• Control valve installation is made easy because the distributor
tube can be cut ½” above to ½” below the top of tank thread.
The distributor tube is held in place by an o-ring seal and
the control valve also has a bayonet lock feature for upper
distributor baskets.
Pre-Installation Considerations
A. Water Pressure
A minimum of 25 pounds of water pressure is required for
regeneration valve to operate effectively. Do not exceed maximum
water pressure of 125 pounds of water pressure.
B. Electrical Facilities
A continuous 120 volt, 60 Hertz current supply is required. Make
certain the current supply is always hot and cannot be turned off
with another switch.
C. Existing Plumbing
Condition of existing plumbing should be free from lime and iron
buildup. Piping that is built up heavily with lime and/or iron should
be replaced. If piping is clogged with iron, a separate iron filter unit
should be installed ahead of the water softener.
D. Where to Install the Softener
Consider the following points when determining where to install the
water softener:
• Place the system as close as possible to a sewer drain.
• Do not install the softener where it would block access to the
waterheater, or access to the main water shutoff, water meter, or
electrical panels.
• Keep outside faucets on hard water to save soft water and salt.
• Install the softener in a place where water damage is least likely to
occur if a leak develops.
• A 120VAC electrical outlet is needed to plug in the transformer. If
the outlet is remote (up to 100 feet), use 18 gauge wire to connect.
• Always connect the system to the main water supply pipe before
the water heater.
• Install the system where it will not be subject to temperatures
outside of the limits stated in the Specification section or to direct
sunlight.

E. Bypass Valves
Always provide for the installation of a bypass valve.
F. Valve to Tank Installation Instructions
1. Spin the valve onto the tank, ensuring the threads are not cross-
threaded.
NOTICE
The control valve have right-hand threads, or clockwise, to install
2. Rotate the valve freely without using force until it comes to a stop
(this position is considered zero).
3. Rotate the valve clockwise from zero, between ¼ turn and ½
turn to fully tighten. No tools are needed. Hand tight is enough.
Overtightening may cause valve or tank damage.
NOTICE
If lubricant is required, a silicone compound is strongly
recommended. Dow Corning
Watts), is recommended for best possible results. Dow Corning
Release Compound is used in the manufacture of this control valve.
The use of other types of lubricants may attack the control’s plastic
or rubber components. Petroleum-based lubricants can cause
swelling in rubber parts, including O-rings and seals.

Pre-Installation Considerations
(continued)
G. Pre Installation and Loading of Media
Systems that are 13” in diameter and larger are not loaded with
media. These systems must be loaded with media before placing
into service. To load a system follow the below steps.
1. Cap the top open end of the distributor tube with tape and
plastic sheeting to keep foreign debris from entering the
distributor tube. This cap must be secure and not come off
during media loading.
2. Place the distributor tube, screen end down, into the mineral
tank and center it in the bottom. The top of the distributor tube
should be flush with the top of the tank.
3. Make sure the plastic and tape cap is secure to the top of the
distributor tube, place a funnel on the top of the tank and load
first the gravel (if different sizes of gravel are used load the
largest gravel first, then the smaller gravel) then the resin media
into the tank. The cap must not come off of the distributor tube
during the loading of the media.
4. Remove the plastic cap from the distributor tube. DO NOT
PULL UP ON THE DISTRIBUTOR TUBE when removing the
cap. The distributor tube top must remain flush with the top of
the tank.
5. Clean any media from the threads and top of the mineral tank.
6. Lubricate the O-rings on the bottom of the control valve
(distributor pilot O-ring and top of tank O-ring). Use nonpetroleum based silicone lubricant only.
7. Place the control valve on top of the tank. When doing this
step, seat the top of the distributor tube inside the centered
O-ring sealed port on the bottom of the valve first then press
the valve down until the tank threads come in contact with the
valve threads. This ensures that the distributor tube is properly
seated into the bottom of the control valve. Thread the valve
on to the tank clockwise. Be careful not to cross thread the
valve or over tighten it. A hand tight snug fit is appropriate for
the control valve torque. A wrench is not necessary. Do not use
thread sealant or PTFE tape on the valve base threads.
8. The system is now ready for installation. Follow the Installation
Section in the Installation, Operation and Maintenance Manual.
Installation Preview (continued)
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.
NOTICE
Softener to be located at least 10 feet away from hot water heater to
protect against hot water back-up.
!
WARNING
When piping with copper, solder all piping as sub-assemblies 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.
NOTICE
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 over-flow 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.
!
WARNING
Do not exceed water pressure of 120 psi (8.2 bar). Do not
exceed 110°F (43.3°C). Do not subject unit to freezing
conditions.
Installation Preview
Conduct a visual check of all equipment for any damage that may
have occurred during shipment.
NOTICE
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 dam-age 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.
NOTICE
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 pressure-reducing 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.
Installation Instructions.
1. Turn off water heater(s).
2. Turn off the main water supply to the home and open an inside
faucet (cold and hot) to relieve any pressure within the plumbing
system.
Select Location
1. Place the system in the desired installation location. Make sure
that the location is level and sturdy enough to support the weight
of the system once it is in operation.
2. You will need to 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.
3. You will need a drain close by for disposal of regenerated wastewater.
4. If installing the softener in an outside locations, make sure to
protect softener from the elements, such as freezing temperatures, rain, sunlight and contamination
Install a By-Pass
NOTICE
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.

NOTICE
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.
NOTICE
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.

supply valve (user supplied) in the supply line and close it.
2. Connect the feed water line to the home to the outlet of the
system.
3. Make sure floor is level.
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.
NOTICE
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.
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 tape must
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.

Connect the Drain Line
1. Plumb the drain line to an appropriate drain abiding by all local,
city, and state codes. Use a 3/4” drain line for backwash flow
rates of 7 gpm or for drain lines of 7 gpm and less that exceed
20’ in length. Use a 1” drain line for backwash flow rates of 10
gpm and 12 gpm.
2. 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. 7 on page 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.
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 o-rings, split
rings, and bypass valve or control valve. Solvent cements and primers should be used in accordance with the manufacturer’s instructions.
