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 lubrications 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 red or clear lip seals.
The nuts and caps are designed to be unscrewed or tightened by hand or with the optional maintenance wrench (p/n
V3193). If necessary, 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 any other sealant on threads. Teon 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. Teon tape is not necessary on the nut
connection or caps because of o-ring seals.
After completing any valve maintenance involving the drive assembly and pistons, unplug power source jack from the
printed circuit (PC) board (black wire) and plug back in. This resets the electronics and establishes the service position.
All plumbing should be done in accordance with local plumbing codes. The pipe size of the drain line should be a
minimum of 1/2”. Backwash ow 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 ow control tting. Leave at least 6” between
the drain line control and tting 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 p/n V3007 (inlet and outlet - see page 9), 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.

INSTALLATION
Place lter in desired location close to water supply inlet, after
pressure tank, and near a source for waste water, (utility sink, oor
drain or sewer line). A 115/120V, 60Hz uninterrupted outlet is required.
Keep lter far enough away from walls and other obstructions to allow
enough room for servicing the unit. If a water softener is also to be
installed, generally it will be placed in line after the neutralizer or lter.
From water supply→ neutralizer → lter → softener → to service
ADD MINERALS:
Remove control valve from mineral tank by turning counter-clockwise. Plug open end (top) of distributor tube assembly to
prevent mineral from entering (Fig. A). Add Mineral. DO NOT OVERFILL. There must be at least 16” of space between
the top of the tank and mineral (Fig. B). Remove plug from the top of the distributor tube.
Install control valve making sure the distributor tube is slipped into the center hole on the bottom of the control valve. Pipe
lter into service line. Use of a bypass valve is recommended. Arrows are molded into valve and bypass valve to show
direction of ow.

OPTIONAL BYPASS VALVE: The bypass valve easily connects to the control valve body using nuts that only require
hand tightening. Install with red knobs in the upward position. Press end of bypass valve with o-rings into valve. Hand
tighten nuts. Place into BYPASS OPERATION (Fig. 4).
Avoid getting primer and solvent cement on any part of the o-rings or split rings, bypass valve or control valve. DO NOT
use pipe dope or any other sealant on threads. Teon tape is not necessary on the caps because of o-ring seals. DO
NOT use Vaseline or other unacceptable lubricants on o-rings. A silicone lubricant may be used on black o-rings.
DRAIN LINE: The 3/4” drain line elbow accommodates 5/8” poly tube or 3/4” NPT drain line connections. The nut and
poly tube insert for the 3/4” drain line elbow is designed for use with exible,
semi-rigid poly tube only. The drain line elbow can be rotated so the outlet can
be oriented toward the nearest drain.
TO INSTALL 5/8” POLY TUBE DRAIN LINE: The poly tube insert is shipped
attached to the drain line elbow’s locking clip. Press the insert into the drain line
(5/8” poly tube not included). Loosen nut of the drain line elbow. Press 5/8” poly
tube with insert into the drain line elbow until it seats on the back of the tting.
Tighten nut.
The drain line must be piped to an open drain with air gap between the drain
and the sewer lines (Fig. 3). Under no circumstances should there be a direct
connection with sanitary sewage facilities. If it is necessary to run the drain pipe
overhead, (not to exceed 5’ above valve) be sure to increase the pipe size and
follow all plumbing procedures to hold friction and restrictions to a minimum.

PLACING UNIT INTO SERVICE: Make sure inlet and outlet valves are to their closed positions. If using optional bypass,
place in bypass position. Turn on main water supply. Open a cold water faucet. This will clear the lines of any debris
(solder, pipe dope, etc.) that may be in the line. Let water run at tap for a couple of minutes, or until clear. Turn off faucet.
• Press and hold the ▲ and▼ buttons simultaneously for approximately 5 seconds until the motor starts. Wait until
display reads C1. This is the rst BACKWASH position.
• If using optional bypass SLOWLY turn bypass valve to DIAGNOSTIC MODE (Fig. 5) or slowly open inlet valve
to allow water to slowly enter the lter.
• When water is owing steadily to drain without the presence of air and no mineral “FINES” are seen,
momentarily press ▲ button again. Display will read C4. This is the nal rinse position.
• Open the outlet valve of the lter, or if using optional bypass place to NORMAL OPERATION MODE (Fig. 6).
• Momentarily press ▲ button again. C0 will appear for a few seconds while control valve returns to the ltering
position.

ADDITIONAL PROGRAMMING INFORMATION AVAILABLE FROM
LANCASTER WATER TREATMENT UPON REQUEST.
INCLUDES: 7-DAY OPTION, REGENERATION CYCLES, TIMES AND 50 Hz.
ACID NEUTRALIZERS, (7-LETDAN-): Mineral used: Calcite. Calcite will dissolve in proportion to the amount of acid in the raw water.
The amount of calcite in the tank should be monitored and replaced periodically. A tank with a dome plug is provided so that calcite may
be added without removing the control valve. To check level of calcite in the mineral tank shut off water supply to the lter. Press and
hold the ▲ and▼ buttons until the lter goes into backwash. Unplug valve from power supply. This will relieve the pressure in the tank.
Remove hexagonal dome plug. A small amount of water will be lost from the tank. Insert a dipstick into the dome hole until the stick
reaches mineral level. Mark and remove the stick. Measure the marked distance on the stick. This number should never be less than
16”. Replace calcite before the mineral level is 24” from the dome hole. Adding calcite will displace the water in the tank. This water may
be siphoned out to reduce spillage. As each installation will use a different amount of calcite, monitoring the mineral level once a month
for the rst few months of operation should give a fairly good indication as to how frequently the calcite will need to be replenished. Re-
place the dome plug. Turn on the water supply to the neutralizer. Plug valve into power supply. Allow water to run to drain for a couple
of minutes to allow “Fines” to backwash to drain. Press and release the ▲ button. Display will read C4. Press and release the ▲ button
again. Time of day will need to be reset.
A pH test kit may also be used to monitor the pH level to help determine when mineral needs to be replenished. Calcite will add approxi-
mately four (4) or more grains per gallon to the original hardness of the raw water. This should be kept in mind when guring regenera-
tion cycle for a water softener. If a Corosex/Calcite mixture is recommended to be used (for high ow rates or very low pH level), mix
one part Corosex with four parts Calcite BEFORE adding to the tank. NOTE: 1 cu ft. of calcite = 85 lbs.
IRON FILTERS, (7-LETIM-, 7-LETIMG-): Mineral used: Birm. No chemical regenerant is required, backwash periodically. No hardness
is added to the water. For clear water iron, when the pH is less than seven (7) in the raw water, a water softener should be used in
place of the iron lter. Note: When using Birm for iron removal, it is necessary that the water: contain no oil or hydrogen sul-
de, organic matter not to exceed 4-5 ppm, the D.O. content equal at least 15% of iron content with a pH of 6.8 or more. If the
inuent water has a pH of less that 6.8, neutralizing additives such as Calcite, Corosex or soda ash may be used prior to the
Birm lter to raise the pH. A water having a low D.O. level may be pretreated by aeration. Chlorination greatly reduces Birm’s
activity. High concentrations of chlorine compounds may deplete the catalytic coating.
COLOR, TASTE AND ODOR FILTERS, (7-LETCT-, LETCTG-): Mineral used: Carbon. Used for removal of chlorine, color, taste, odor
and low levels of sulfur, etc. The mineral bed should be backwashed periodically, but will in time reach the maximum absorbency. When
this occurs the carbon should be completely replaced.
SEDIMENT AND TURBIDITY, (7-LETST-): Mineral used: Filter AG. This lter will lter out dirt, silica, etc. down to the 20-40 micron
range. In most cases it has a lifetime ll and should be backwashed periodically depending on local conditions. Pressure drop is very
low.
DRIVE ASSEMBLY:
Remove the valve cover to access the drive assembly.
Disconnect the power source plug (black wire) from the PC board prior to disconnecting the motor plug from the PC board. The motor
plug connects to the two-pin jack on the left-hand side of the PC board. The power source plug connects to the four-pin jack.
The PC board can be removed separately from the drive bracket but it is not recommended. Do not attempt to remove the display panel
from the PC board. Handle the board by the edges. To remove the PC board from the drive bracket, unplug the power and motor plugs
from the PC board. Lift the middle latch along the top of the drive bracket while pulling outward on the top of the PC board. The drive
bracket has one plastic pin that ts into the hole in the lower edge of the PC board. Once the PC board is tilted about 45° from the drive
bracket it can be lifted off the pin. To reinstall the PC board, position the lower edge of the PC board so that the hole in the PC board
lines up with the plastic pin. Push the top of the PC board towards the valve. Align the upper hole on the left hand side of the PC board
with the pin and push in until the PC board snaps under the middle latch, weave the power wire into the holders and reconnect the mo-
tor and power plugs.
The drive bracket must be removed to access the drive cap assembly and pistons or the drive gear cover. It is not necessary to remove
the PC board from the drive bracket to remove the drive bracket. To remove the drive bracket start by removing the plug for the power
source. Unweave the wire from the side holders. Two tabs on the top of the drive back plate hold the drive bracket in place. Simulta-
neously lift the two tabs and gently ease the top of the drive bracket toward your body. The lower edge of the drive bracket has two
notches that rest on the drive back plate. Lift up and outward on the drive bracket to disengage the notches.
To reassemble seat the bottom of the drive bracket so the notches are engaged at the bottom of the drive back plate. Push the top of
the drive bracket towards the two latches. The drive bracket may have to be lifted slightly to let the threaded piston rod pass through
the hole in the drive bracket. Maintain a slight engaging force on the top of the drive bracket while deecting the bracket slightly to the
left by pressing on the side of the upper right corner. This helps the drive gears mesh with the drive cap assembly. The drive bracket is
properly seated when it snaps under the latches on the drive back plate. If resistance is felt before latching, then the notches are not
fully engaged, the piston rod is not in the hole, the power wire is jammed between the drive bracket and the drive plate, or the gear is
not engaging the drive cap assembly.
SERVICE INSTRUCTIONS

DRIVE ASSEMBLY CONTINUED
To inspect drive gears, the drive gear cover needs to be removed. The drive gear is held in place on the drive bracket by three clips.
The largest of the three clips is always oriented to the bottom of the drive bracket. Before trying to remove the drive gear cover, the
drive bracket must be removed from the drive back plate. The drive gear cover can be removed from the drive bracket without removing
the PC board. Simultaneously, push in and down on the large clip at the bottom and the clip on the left-hand side of the drive bracket
behind the PC board. Keep your other ngers behind the drive gear cover so the drive gears do not drop on the ground.
Replace broken or damaged drive gears. Do not lubricate any of the gears. Avoid getting any foreign matter on the reective
coating because dirt or oils may interfere with pulse counting.
The drive gear cover only ts on one way, with the large clip oriented towards the bottom. If all three clips are outside of the gear shroud
on the drive bracket the drive gear cover slips easily into place.
The drive bracket does not need to be removed from the drive plate if the motor needs to be removed. To remove the motor,
disconnect the power and motor plugs from the jacks on the PC board. Move the spring clip loop to the right and hold. Rotate the motor
at least a ¼ turn in either direction before gently pulling on the wire connectors to remove the motor. Pulling directly on the wire without
rotating the motor may break the wires off the motor.
Replace the motor is necessary. Do not lubricate the motor or the gears. When reinstalling the motor gently turn the motor while insert-
ing so that the gear on the motor meshes with the gears under the drive gear cover and the small plastic plug engages one of the slots
on the motor housing. Reconnect the motor plug to the two pronged jack on the lower left-hand side of the PC board. If the motor will
not easily engage with the drive gear when reinstalling, lift and slightly rotate motor before reinserting.
Replace the valve cover. After completing any valve maintenance, press and hold SET HOUR and ▼ buttons for 5 seconds or unplug
power source jack (black wire) from the circuit board and plug back in. This resets the electronics and establishes the
ltering position. Reset the time of day.
DRIVE CAP ASSEMBLY, MAIN PISTON AND REGENERANT PISTON:
The drive assembly must be removed to access the drive cap assembly. The drive cap assembly must be removed to access the
piston(s). The drive cap assembly is threaded into the control valve body and seals the o-ring. To remove the drive cap assembly use
the optional maintenance wrench or insert a ¼” to ½” at bladed screwdriver into one the slots around the top 2” of the drive cap as-
sembly so it engages the notches molded into the drive back plate around the top 2” of the piston cavity (see drawing
below). The notches are visible through the holes. Lever the screwdriver so the drive cap assembly turns counter clockwise. Once loos-
ened unscrew the drive cap assembly by hand and pull straight out.
The drive cap assembly contains the drive cap, the main drive gear, drive cap spline, piston rod and various other parts that should not
be disassembled in the eld. The only replaceable part on the drive cap assembly is the o-ring. Attached to the drive cap assembly is
the main piston and, if a regenerant is used, a regenerant piston.
The regenerant piston (the small diameter one behind the main piston) is removed from the main piston by unsnapping it from its latch.
Chemically clean in dilute sodium bisulte or vinegar or replace the regenerant piston if needed. To remove the main piston fully extend
the piston rod and then unsnap the main piston from its latch by pressing on the side with the number. Chemically clean in diluted so-
dium bisulte or vinegar or replace the main piston.
Reattach the main piston to the drive cap assembly. Reattach the regenerant piston (if needed) to the main piston. Do not lubricate the
piston rod, main piston or regenerant piston. Lubricant will adversely affect the red or clear lip seals. Reinsert the drive cap assembly
and piston into the spacer stack assembly and hand tighten the drive cap assembly. Continue to tighten the drive cap assembly using
the maintenance wrench or screwdriver as a ratchet until the black o-ring on the spacer stack assembly is no longer visible through the
drain port. Excessive force can break the notches molded into the drive back plate. Make certain the main drive gear still turns freely.
The exact position of the piston is not important as long as the main drive gear turns freely.
Reattach the drive assembly to the control valve and connect all plugs. After completing any valve maintenance, press and hold SET
HOUR and ▼ buttons for 5 seconds or unplug power source jack (black wire) from the circuit board and plug back in. This resets the
electronics and establishes the ltering position. Reset the time of day.

PAGE 7
SPACER STACK ASSEMBLY:
To access the spacer stack assembly remove the drive assembly, drive cap assembly and piston. The spacer stack as-
sembly can be removed easily without tools by using your thumb and forenger. Inspect the black o-rings and red or clear
lip seals for wear or damage. Replace the entire stack if necessary. The spacer stack assembly has been 100% tested at
the factory to insure proper orientation of one way seals. DO NOT disassemble spacer stack.
The spacer stack assembly may be chemically cleaned (dilute sodium bisulte or vinegar) or wipe with a soft cloth.
The spacer stack assembly can be pushed into the control valve body bore by hand. Since the spacer stack assembly can
be compressed it is easier to use a blunt object (⅝” to 1⅛” in diameter) to push the center of the assembly into the control
valve body. The assembly is properly seated when at least four threads are exposed (approximately ⅝”) DO NOT force
the spacer stack assembly in. The control valve body bore interior can be lubricated with silicone to allow for easy inser-
tion of the entire stack. Do not use silicone or any other type of lubricant on the red or clear lip seals or the piston.
Reattach the drive cap assembly and piston(s) and the drive assembly.
After completing any valve maintenance, press and hold SET HOUR and ▼ buttons for 5 seconds or unplug power
source jack (black wire) from the circuit board and plug back in. This resets the electronics and establishes the ltering
position. Reset the time of day.
INJECTOR CAP, SCREEN, INJECTOR PLUG AND INJECTOR:
Unscrew the injector cap and lift off. Loosen cap with optional maintenance wrench or pliers if necessary. A screen is at-
tached to the injector cap. Remove the screen and clean if fouled.
The plug and/or injector can be pried out with a small screwdriver. The plug can be wiped clean. If the plug leaks replace
the entire plug. The injector consist of a throat and a nozzle. Chemically clean the injector with vinegar or dilute sodium
bisulte. The holes can be blown out with air. Both pieces have small diameter holes that control the ow rates of the
water to insure that the proper concentration of the regenerant is used. Sharp objects, which can score the plastic, should
not be used to clean the injector. Scoring the injector or increasing the diameter of the hole could change the operating
parameters of the injector.
Two holes are labeled DN and UP. For down ow systems, the appropriate injector is located in the “DN” hole, a plug is in
the “UP” hole. Push the plug and injector rmly in place, replace the screen and hand tighten the injector cap.
REFILL FLOW CONTROL ASSEMBLY OR REFILL PORT PLUG:
To clean or replace the rell ow control, pull out the elbow-locking clip and then pull straight up on the elbow. Replace the
elbow locking clip in the slot so that it is not misplaced. Twist to remove the white ow control retainer. The ow control
can be removed by prying upward through the side slots of the retainer with a small blade at screwdriver.
Chemically clean the ow control or the white ow control retainer using dilute sodium bisulte or vinegar. Do not use a
wire brush. If necessary, replace the ow control, o-ring on the ow control retainer, or the o-ring on the elbow.
Reseat the ow control so the rounded end is visible in the ow control. Reseat the white ow control retainer by pushing
the
retainer into the elbow until the o-ring seats. Remove locking clip, push down on elbow to reseat and insert locking clip.
DO NOT use Vaseline, oils, or other unacceptable lubricants on o-rings. A silicone lubricant may be used on the o-ring on
the elbow or white retainer.
METER PLUG:
This control valve does not come equipped with a meter, instead a plug is installed. The plug should not need to be ser-
viced.
To remove the meter plug assembly, unscrew the meter cap on the left side of the control valve. Pliers may be used to
unscrew the nut if necessary.
With the nut removed, a slot at the top of the meter plug is visible. Twist a at blade screwdriver in the slot between the
control valve body and the meter plug. When the meter plug is part way out it is easy to remove the meter plug from the
housing.
DO NOT use a wire brush to clean. Wipe with a clean cloth or chemically clean in dilute sodium bisulte or vinegar.
DO NOT use Vaseline, oils, or other unacceptable lubricants on o-rings. A silicone lubricant may be used on the black
o-ring.
Reinsert the meter plug into the side slot. Hand tighten the nut. Do not use a pipe wrench to tighten nut.

BYPASS VALVE:
The working parts of the bypass valve are the rotor assemblies that are contained under the bypass valve caps. Before
working on the rotor, make sure the system is depressurized. Turn the red arrow shaped handles toward the center of the
bypass valve and back to the arrow direction several times to ensure rotor is turning freely.
The nuts and caps are designed to be unscrewed or tighten by hand. 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. To access the rotor, unscrew the cap and lift the cap, rotor and handle out as one unit. Twisting the
unit as you pull it out will help to remove it more easily. There are three o-rings: under the bypass cap, on the rotor stem
and on the rotor seal. Replace worn o-rings. Clean rotor. Reinstall rotor.
When reinstalling the red arrow handles be sure that:
1. O-rings on both rotors face to the right when being viewed from the front of the control valve when the
handle pointers are lined up with the control valve body arrows; or
2. Arrows point toward each other in the bypass position.
Since the handles can be pulled off, they could be accidentally reinstalled 180° from their correct orientation. To install the
red handles correctly, keep the handles pointed in the same direction as the arrows engraved on the control valve body
while tightening the bypass valve caps.
After completing any valve maintenance, press and hold SET HOUR and ▼ buttons for 5 seconds or unplug power
source jack (black wire) from the circuit board and plug back in. This resets the electronics and establishes the ltering
position. Reset the time of day.
OPTIONAL MAINTENANCE WRENCH
V3193
Although no tools are necessary to assemble the valve, the optional maintenance wrench (shown in various positions on
the valve) may be purchased to aid in assembly or disassembly.
