Introduction
This manual is about a control valve to be used on water softeners or water lters. The manual is designed to aid water treatment
equipment manufacturers in the selection of the various control valve options. Information in this manual is different than what is
needed for installation and servicing of a particular water treatment system. This manual is not intended to be used as a manual for
a complete water softener or lter. Certain parts of the manual will serve as aids to manufacturers in the writing and layout of the
manuals for installers and service personnel.
General Warnings (Must appear in OEM’s manual)
The following general warnings and the specications in Table 1 must appear in the OEM’s System Manual.
The control valve, ttings 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 silicone lubricant may be used on black
o-rings but is not necessary. Avoid any type of lubricants, including silicone, on the 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 a screwdriver in the slots on
caps and/or tap with a hammer.
Do not use pipe dope or other sealants on threads. Use teon tape on threaded inlet, outlet and drain ttings. Teon 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, unplug power source
jack from the printed circuit board (black wire) and plug back in. This resets the electronics and establishes the service piston
position.
All plumbing should be done in accordance with local plumbing codes. The pipe size for the drain line should be a minimum of ½”.
Backwash ow rates in excess of 7 gpm or length in excess of 20’ require ¾” drain line.
Solder joints near the drain must be done prior to connecting the drain line ow control tting. Leave at least 6” between the drain
line control tting and solder joints when soldering pipes that are connected on the drain line control tting. Failure to do this could
cause interior damage to the drain line ow control tting.
When assembling the installation tting package (inlet and outlet), connect the tting to the plumbing system rst 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.

Control Valve Function and Cycles of Operation
This glass lled Noryl
all cycles of a downow regeneration water softener or lter.
The time clock control valve can be set to perform downow regeneration or simply backwash. The time clock control valve has
two calendar options for regeneration frequency:
1. an option where the user can choose the number of days (1-99) between each regeneration; and
2. a seven-day option where the user can choose which day(s) of the week a regeneration should occur.
The control valve is compatible with a variety of regenerants and resin cleaners. The control valve is capable of routing the ow
of water in the necessary paths to regenerate or backwash water treatment systems. The injector regulates the ow of brine or
other regenerants. The control valve regulates the ow rates for backwashing, rinsing, and the replenishing of treated water into a
regenerant tank, when applicable.
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 rmly hand tightened because radial seals are used. Tools required to service the valve include one
small blade screw driver, one large blade screw driver, 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.
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.
The AC adapter power pack comes with a 15 foot power cord and is designed for use with the control valve. The AC adapter power
pack is for dry location use only. If the power goes out, only the time of day needs to be reset. All other values are permanently
stored in the nonvolatile memory.

(or equivalent) fully automatic control valve is designed as the primary control center to direct and regulate
Table 3 shows the time for the backwash, regenerative, and rinse cycles for the ten available programming options. Six different
programs are available for a softener, one for a regenerative lter, and three programs for backwash only lters. When the control
valve is used as a:
1. softener, one or two backwashes occur and rell always occurs after the rinse cycle (P0 through P5);
2. regenerative lter, one backwash occurs and rell always occurs after the rinse cycle (P6); and
3. backwashing lter, one backwash occurs (P7 through P9).

The user can initiate manual regeneration. The user has the option to request the manual regeneration at the delayed regeneration
time or to have the regeneration occur immediately. Simultaneously press the UP + DOWN buttons to start a regeneration at the
next delayed regeneration time. If a regeneration is to occur today an arrow will point to regeneration. For immediate regeneration,
simultaneously press and hold the UP + DOWN buttons for three seconds.
When in regeneration, step through the different regeneration cycles by simultaneously pressing the UP + DOWN buttons.

Page 8 WS1TC & WS1.25 TC Manual
Drive Assembly
The drive assembly consists of the following parts:
• Drive Bracket
• Printed Circuit (PC) Board
• Motor
• Drive Gears
• Drive Gear Cover
The drive bracket holds the PC board, the motor, the drive gears and the drive gear cover in place.
The PC board receives and retains information, displays the information, determines when to regenerate and initiates regeneration.
The PC board powers the motor. The PC board’s two-prong jack connects wires to the direct current (DC) motor. The motor is held
in place on the drive bracket by a spring-loaded clip and a small bulge in the plastic, which ts in one of the slots on the motor
housing. The motor turns drive gears that drive the piston to cycle positions for backwashing, regeneration, rinsing, rell or service.
The motor is fully reversible (turns both ways) and changes direction of rotation to change the direction of piston motion. The motor
is easily replaced if necessary.
There are three drive gears held in place by the drive gear cover. All three drive gears are the same size. A reective coating is
applied to the gears. As the center drive gear turns a light shines on the coating and a light sensing diode determines if a light pulse
was returned. The PC board counts the pulses and determines when to stop driving the motor.
Drive Cap Assembly, Downow Piston and Regenerant Piston
The drive gears turn the main gear of the drive cap assembly, which moves the piston. The screw-driven, horizontally moving
piston stops at specic positions to direct the ow of water to backwash, regenerate, rinse or rell. The PC board determines the
position of the piston by counting pulses produced when the piston is moved. An optical sensor looking at one of the reduction
drive gears generates these pulses. Each cycle position is dened by a number of pulses. The counter is zeroed each time the valve
goes to the service position. The PC board nds the service position by noting the increase in current delivered to the motor when
the mechanical stop at the service position is reached. This method of controlling piston position allows for greater exibility and
requires no switches or cams (U.S. Patent 6444127).
The downow piston is used when the control valve is used as a downow softener, regnerating lter or non-regenerating lter. If
the control valve is used as a softener or a regenerating lter, a regenerant piston must be attached to the downow piston. If the
control valve is to be used on system that does not require a regenerant to be added, the regenerant piston must be removed.
One of two main pistons is always used:
1. A 1.25" diameter downow piston is used when the WS1TC control valve is used as a downow softener, regenerating lter or
non-regenerating lter.
2. A 1.5" diameter downow piston is used when the WS1.25TC control valve is used as a downow softener, regenerating lter
or non-regenerating lter.
If the control valve is used as a softener or a regenerating lter, a regenerant piston must be attached to the main piston. If the
control valve is to be used on a system that does not require a regenerant to be added, the regenerant piston must be removed.
Spacer Stack Assembly
The spacer stack assembly provides the necessary ow passage for water during the different cycles. The all-plastic spacer stack
assembly (U.S. Patent 6402944) is a one-piece design which allows the stack to be removed using your ngers.
The exterior of the stack is sealed against the body bore with self lubricating EPDM o-rings, while the interior surface is sealed
against the piston using slippery self cleaning directional (one-way) silicone lip seals. The lip seals are clear and have a special
slippery coating so that the piston does not need to be lubricated.
WS1TC & WS1.25 TC Manual Page 9
Injector Cap, Screen, Injector Plug and Injector
The screen, injector and/or injector plug(s) are installed under the injector cap in an easy to access location on top of the valve. The
injector cap contains four slots so no water accumulates in the cap. The injector cap is designed to be hand tightened.
Under the injector cap there is an easy to clean removable screen to prevent fouling of the injector. There are two holes under the
injector cap labeled “DN” and “UP”. The holes will be lled with a plug or an injector.
The plug (Order # V3010-1Z) prevents water from traveling a certain pathway. The injector lets water pass through the pathway.
The self-priming injector increases the velocity of the water, creating a zone of negative pressure that draws in the concentrated
liquid regenerant, such as sodium chloride (brine), potassium permanganate, etc. The regenerant blends with the stream of water,
which passes through the media to regenerate the bed.
The injector provides a consistent regenerant/water mixture ratio over the entire operating pressure range of the control valve. The
injector provides good performance in a variety of applications, which may involve elevated drain lines and long regenerant draw
lengths. Injectors are chosen by knowing the type, amount, and regenerant ow rate for a particular type of media. Guidelines can
be found in the media manufacturer’s literature. The color coded injectors give different regenerant draw, slow rinse and total ow
rates over the pressure range. See Table 4 for color codings, and injector graphs for total, slow rinse and draw ow rates.

The control valve has been designed so that the OEM can rapidly change the control valve to allow for the following options:
• regeneration downow (for softeners or regenerating lters install injector in DN location, plug in UP location); or
• no regeneration (both the DN and UP holes have injector plugs installed) and plug installed for the rell elbow.
Rell Flow Control Assembly or Rell Port Plug
The rell ow control assembly consists of a rell ow elbow, rell ow control retainer assembly, rell ow control, polytube
insert and nut assembly. The rell ow control retainer ts in the rell elbow. The rell ow control retainer houses the rell ow
control which controls the ow rate when the regenerant tank is being relled. The rell ow control is a exible washer-like
part with a small orice and a precision molded contour that delivers a steady 0.5 gpm regenerant tank rell rate at varying inlet
pressures. Rell is accomplished with treated water.
2
Actual tank size used may vary depending on the design and application of the system. Tank diameter is an approximation for a
downow softener using standard mesh synthetic cation exchange media regenerating with sodium chloride.
Page 10 WS1TC & WS1.25 TC Manual
The rell ow control assembly is installed in an easy to access rell elbow located on top of the control valve. The rell ow
control assembly is attached to the control valve with a locking clip. The locking clip allows the elbow to rotate 270 degrees so the
outlet can be orientated towards the regenerant tank.
The control valve has a standard rell elbow to which a 3/8” exible tube can be connected. An optional elbow can be ordered
which accommodates a ½” exible tube for a high regenerant draw rate situation (G injectors and larger). Both elbows use the same
rell ow control and retainer.
If the control valve is to be used as a non-regenerant lter control valve, the rell elbow is removed and replaced with a rell port
plug P/N V3195-01.
Drain Line Flow Control and Fitting Assembly
The drain line ow control assembly includes a drain line ow control and a tting. The drain line ow control allows proper media
bed expansion by regulating the ow rate to the drain. The drain line ow control is a exible washer-like part with an orice and
a precision molded contour. The ow rates are within ± 10% over the pressure range of 20 psi to 125 psi. See Table 5 for ow rate
information.

The drain line ow control and tting are located on top of the control valve and replaceable without the use of special tools.
The drain line ow control can be installed in the standard ¾” drain line elbow, which accommodates 5/8” polytube or ¾” NPT drain
line connections. The optional nut and polytube insert for the ¾” drain line elbow is designed for use with exible polytube only.
The ¾” drain line elbow can be rotated 180 degrees so the outlet can be orientated to the nearest drain. The same retainer is used for
all drain line ow controls for the ¾” tting. Drain line ow controls designed for the ¾” tting are available for ow rates ranging
from 0.7 to 10 gpm.
An optional 1” straight drain line tting is available to accommodate drain line ow rates ranging from 9 to 25 gpm. This tting is
straight but still connects to the control valve using the same locking clip. The drain line ow control is located between two tted
parts (i.e. the tting acts as the retainer). The nut is unscrewed to access the drain line ow control.
WS1TC & WS1.25 TC Manual Page 11
Mixing Valve
The mixing valve is installed on the outlet side of the control valve. The mixing valve is used to blend raw water with treated water.
To adjust the blended water, close the mixing valve. Open a water faucet to the desired ow rate. Open the mixing valve until the
desired hardness is reached. Close the faucet.
Installation Fitting Assemblies
The installation ttings are used to connect the optional bypass or the control valve to the plumbing system. There are eight
installation tting assemblies available:
1. 1” NPT elbow assembly
2. ¾” & 1” PVC solvent weld elbow tting assembly
3. 1” straight brass sweat tting assembly
4. ¾” straight brass sweat tting assembly
5. 1” plastic male NPT tting assembly
6. 1¼” plastic male NPT tting assembly
7. 1” plastic male BSPT tting assembly
8. 1¼” plastic male BSPT tting assembly
9. 1¼” & 1½” brass sweat tting assembly
10. 1¼” & 1½” PVC solvent tting assembly

Both elbow ttings have a unique drill out feature to allow a ¼” NPT connection to the inlet and/or outlet which can be used for a
RO feed, test ports, pressure tap ports, etc.
The installation tting assemblies are sold in pairs and consist of two ttings, two nuts, two split rings and two o-rings. The
installation tting assemblies and the bypass valve are sold separately from the control valve.

Has not been tested for compliance with California Proposition 65, so this tting should not be installed in California.
Page 12 WS1TC & WS1.25 TC Manual
Bypass Valve
The bypass valve is typically used to isolate the control valve from the plumbing system’s water pressure in order to perform control
valve repairs or maintenance. The WS1 bypass valve is particularly unique in the water treatment industry due to its versatility
and state of the art design features. The 1” full ow bypass valve incorporates four positions, including a diagnostic position that
allows service personal to work on a pressurized system while still providing untreated bypass water to the facility or residence. Its
completely non-metallic, all-plastic design allows for easy access and serviceability without the need for tools.
The bypass body and rotors are glass lled Noryl4 (or equivalent) and the nuts and caps are glass lled polypropylene. All seals are
self-lubricating EPDM to help prevent valve seizing after long periods of non-use. Internal o-rings can easily be replaced if service
is required.
The bypass consists of two interchangeable plug valves that are operated independently by red arrow-shaped handles. The handles
identify the ow direction of the water. The plug valves enable the bypass valve to operate in four positions.
1. Normal Operation Position: The inlet and outlet handles point in the direction of ow indicated by the engraved arrows
on the control valve. Water ows through the control valve during normal operation and this position also allows the
control valve to isolate the media bed during the regeneration cycle. (See Figure 1)
2. Bypass Position: The inlet and outlet handles point to the center of the bypass, the control valve is isolated from the water
pressure contained in the plumbing system. Untreated water is supplied to the plumbing system. (See Figure 2)
3. Diagnostic Position: The inlet handle points in the direction of ow and the outlet handle points to the center of bypass
valve, system water pressure is allowed to the control valve and the plumbing system while not allowing water to exit from
the control valve to the plumbing. (See Figure 3)
4. Shut Off Position: The inlet handle points to the center of the bypass valve and the outlet handle points in the direction of
