The control valve, tting 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
(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 a screw driver in the slots on
caps and/or tap with a hammer.
Do not use pipe dope or other sealants on threads. Use
Teon tape on the threaded inlet, outlet and drain ttings.
Teon tape is not necessary on the nut connection or caps
because of o-rings 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 or press and hold NEXT
and REGEN buttons for 3 seconds. This resets the electronics
and establishes the service piston position. The display
should ash the software version and then reset the valve
to the service position.
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-ring, split rings, bypass valve or control
valve.
Install grounding strap on metal pipes.
This water lter is not to be used for treating water
that is microbiologically unsafe or of unknown
quality without adequate disinfection before or after
treatment.
GENERAL INSTALLATION
AND SERVICE WARNINGS
PRE-INSTALLATION
REVIEW
WATER PRESSURE: A minimum of 20 pounds of water
pressure (psi) is required for backwash. Maximum 100
psi. CAUTION: the lter cannot be subject to a vacuum
due to loss of pressure (such as a water main break or
submersible well pump check valve failure).
WATER TEMPERATURE: The range of water temperature
is 35°F to 100°F. DO NOT install any water lter with less
than 10 feet of piping between its outlet and the inlet of a
water heater.
AMBIENT TEMPERATURE: DO NOT locate lter where it
or its connections (including the drain and overow lines)
will ever be subject to room temperatures under 33°F.
ELECTRICITY: An uninterrupted 120 volt 60Hz source is
required. Make sure electrical source is not on a timer
or switch. All electrical connections must be connected
according to local codes. The plug-in transformer is for
dry locations only. Surge protection is recommended with
all electrical connections.
DRAIN: All plumbing should be done in accordance with
local plumbing codes. The distance between the drain
and the water lter should be as short as possible. The
pipe size for the drain line should be a minimum of 1/2”
(inside diameter of pipe). For backwash rates of 7 gpm or
higher, use a 3/4” drain line.
FILTERING: It is recommended that the lter be installed
to treat both the hot and cold water supply. Outside faucets
should be left on untreated water.
BYPASS: A bypass valve (optional accessory) should
be installed so that water will be available if it should be
necessary to shut off the pressure in order to service the
lter.

PAGE 4
OPERATION:
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 gure
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 gure 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 gure 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 ow, the water is shut off
to the plumbing system. If water is available on the
outlet side of the lter it is an indication of water
bypass around the system (i.e. a plumbing connection
somewhere in the building bypasses the system).
(see gure 4)
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 X-Factor 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 bypassed 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 Noryl® (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.
The working parts of the bypass valve are the rotor assemblies that are contained under the bypass valve caps. Before working on the
rotors, make sure the system is depressurized. Turn the red arrow shaped handles towards the center of the bypass valve and back
several times to ensure rotor is turning freely.
The nuts and caps are designed to be unscrewed or tightened by hand. If necessary a pliers or the service spanner wrench 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.
Refer to page 15 for bypass valve parts diagram and page 16 for service spanner wrench information.
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: one under the rotor cap, one on the rotor stem and the rotor seal. Replace worn
o-rings. Clean rotor. Reinstall rotor.
When reinstalling the red arrow handles be sure that:
1. The handle pointers are lined up with the control valve body arrows, and the rotor seal o-ring and retainer on both rotors face
to the right when being viewed from the front of the control valve; 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 arrow
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.

1. 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 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
2. Add Minerals: Remove control valve from the mineral tank by turning counter-clockwise. Plug open end (top) of the
distributor tube assembly to prevent the mineral from entering (g. A). Add the mineral. DO NOT OVERFILL. Tanks should
be 2/3 full. Remove the plug from the distributor tube. Water can be manually added at this time to begin the mineral soaking
process. Replace the control valve making sure that the distributor tube is inserted into the center hole of the bottom of the
control valve.
3. Do all necessary plumbing (inlet to inlet, outlet to outlet, and drain line to drain). 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.
4. 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
joint 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.
5. A jumper ground wire should be installed between the inlet and outlet pipe whenever the metallic continuity of a
water distribution piping system is interrupted. Install grounding strap on metal pipes.
6. The drain connection may be made using either 5/8” polytube (see below) or a 3/4” female adapter. The polytube insert
is shipped attached to the drain line elbow’s locking clip. Press the insert into the drain line tubing (tubing not provided).
Loosen the nut of the drain line elbow. Press the 5/8” polytube with insert into the drain line elbow until it seats on the back
of the tting. Tighten the nut. If soldering, 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. Never insert a
drain line into a drain, sewer line, or trap. Always allow an air gap between the drain line and the wastewater to prevent the
possibility of sewage being back-siphoned into the lter (g. C).

lter
Check valve
connected here
(see below)
Follow installation instruction in this manual for plumbing the inlet and outlet.
Special precautions must be made when connecting the drain line. Hard piping is
recommended. During backwash, air and water escape quickly, causing a exible drain line to
whip and thrash. Attach the drain line securely to an air gap device on the waste water line.
A check valve is installed in the brine elbow. This must be in place to prevent water from discharging during the backwash
sequence. See diagram below.

Do not plug the transformer into the receptacle yet. 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 line
of any debris (solder, pipe dope, etc.) that may be in the line. Let water run at faucet for a couple minutes, or until clear.
Turn off faucet. Now plug the transformer into a 120 volt receptacle (be certain the receptacle is uninterrupted). Within 5
seconds the control display and buttons will illuminate and the time of day screen will appear.
• Press and hold the REGEN button for approximately 5 seconds until the motor starts.
• Wait until display reads BACKWASH and numbers start counting down. (7-LX125CTAIR and 7-LX125IMAIR models
will have an AIR RELEASE cycle for 5 seconds then BACKWASH will appear.)
If using optional bypass SLOWLY turn bypass valve to DIAGNOSTIC position (See gure 3 on page 4) or slowly open
inlet valve to allow water to slowly enter lter.
Mineral is dry, and lling to quickly with water will result in the mineral plugging the drain line and valve
assembly. Some minerals such as carbon and Filter Ag should not be backwashed immediately for extended
periods of time. These minerals need to soak in water for a 24-hour period before backwashing at full ow. Flow
water to drain very slowly, increasing the ow until the water runs clear.
FOR 7-LX125CTAIR, 7-LX125IMAIR MODELS-
Momentarily press REGEN again. Display will read REGENERANT DRAW DN; allow this cycle to complete. This allows an
air pocket to form for the lter to function properly. Control will automatically advance to the FILTERING position. Open the
outlet valve of the lter, or if using optional bypass place to NORMAL OPERATION MODE (see gure 1 on page 4).
FOR ALL OTHER FILTERS-
When water is owing steadily to drain without the presence of air, momentarily press REGEN again. Display will read
RINSE. Open the outlet valve of the lter, or if using optional bypass place to NORMAL OPERATION MODE (see gure
1 on page 4). Allow control to nish the RINSE cycle. Allow the control to automatically advance to the FILTERING
position.

GENERAL OPERATION
User Displays
When the system is in normal service mode, one of up to four available User Displays will be shown. Pressing NEXT will
alternate between the following displays:
• Current time of day
• Treated water ow rate
• Service contact name and phone number (if entered)
• Remaining days to regeneration (if Day Override is
programmed)
To clear the Service Call reminder, press the and buttons simultaneously while the number and banner text
screen is displayed.
If the system has called for a backwash that will occur at the preset time of backwash, the words REGEN TODAY will
alternate with the header on the display.
Utilizing the control valve’s built-in water meter, a water drop ashes on the display when water is being treated (i.e. water
is owing through the system).
Note: As an energy saving feature, the control will automatically turn off all SOLID BLUE or SOLID GREEN
display illumination and keypad illumination after about 5 minutes of the last keypad button push. Any further
keypad touch will cause the re-illumination of the display and keypad, and re-activate keypad control.

ACID NEUTRALIZERS: 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
REGEN button 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 10”.
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.
Replace the dome plug. Slowly turn on the water supply to the neutralizer. Allow water to run to drain for a couple of minutes to allow
“Fines” to backwash to drain. Plug valve into power supply.
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
approximately four (4) or more grains per gallon to the original hardness of the raw water. This should be kept in mind when
guring regeneration 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: 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 (1-LXIMAIR-). Chlorination greatly reduces Birm’s activity. High concentrations of chlorine
compounds may deplete the catalytic coating.
COLOR, TASTE AND ODOR FILTERS: 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. For removal of chloramines, stronger levels of sulfur, and even iron, special catalytic carbon is
recommended. When catalytic carbon is used for sulfur and iron removal, pretreatment by aeration is recommended to ensure 4 ppm of
D. O. (7-LX125CTAIR-).
SEDIMENT AND TURBIDITY,: 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 (refer to pages 11&12 for diagrams):
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 or water meter plugs from the PC
board. The power source plug connects to the four-pin jack. The motor plug connects to the two-pin jack on the left-hand side of the PC
board. The water meter plug (gray wire) connects to the three-pin jack on the far right-hand side of the PC board.
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, water meter 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 two plastic pins that t into the holes on the lower edge of the PC board. Once the PC board is tilted about 45°
from the drive bracket it can be lifted off of these pins. To reinstall the PC board, position the lower edge of the PC board so that the
holes in the PC board line up with the plastic pins. Push the top of the PC board towards the valve until it snaps under the middle latch,
weave the power and water meter wires into the holders and reconnect the motor, water meter 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 plugs for the power
source and the water meter. Unweave the wires from the side holders. Two tabs on the top of the drive back plate hold the drive bracket
in place. Simultaneously lift the two tabs and gently ease the top of the drive bracket forward. 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 toward 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 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 notches are not fully
engaged, the piston rod is not in hole, the wires are jammed between the drive bracket and drive back plate, or the gear is not engaging
the drive cap assembly.
To inspect the drive gears, the drive gear cover needs to be removed. Before trying to remove the gear cover, the drive bracket must
be removed from the drive back plate. (Refer to the instructions above regarding removing the drive bracket from the drive back plate.
The drive gear cover can be removed from the drive bracket without removing the motor or the PC board.) The drive gear cover is held
in place on the drive bracket by three clips. The largest of the three clips is always orientated to the bottom of the drive bracket. With
the PC board facing up, push in and down on the large clip on the drive gear cover. Handle the cover and the gears carefully so that the
gears do not fall off the pegs in the cover.
SERVICE INSTRUCTIONS

PAGE 19
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 orientated 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 so the wires are vertical (up & down) before gently pulling on the wire connectors to remove the motor. Pulling
directly on the wires without rotating the motor may break the wires off the motor.
Replace the motor if necessary. Do not lubricate the motor or the gears. To reinstall the motor, move the spring clip loop to the right and
hold. Gently turn the motor while inserting so that the gear on the motor meshes with the gears under the drive gear cover. Release the
spring clip loop and continue to rotate the motor until the wires are horizontal and the motor housing engages the small plastic bulge
inside the drive bracket motor retainer. Reconnect the motor plug to the two-pronged jack on the lower left side of the PC board. If the
motor will not easily engage with the drive gears when reinstalling, lift and slightly rotate the motor before reinserting. Reconnect the
power plug.
Replace the valve cover. 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 ash the software version and then reset the
valve to the service position.
DRIVE CAP ASSEMBLY, MAIN PISTON AND (refer to page 11&12 for diagrams):
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 with an o-ring. To remove the drive cap assembly
use the special plastic service spanner wrench (see page 16) or insert a ¼” to ½” at blade screwdriver into one of the slots around the
top 2” of the drive cap assembly so it engages the notches molded into the drive back plate around the top 2” of the piston cavity. See
gure below. The notches are visible through the holes. Lever the screwdriver so the drive cap assembly turns counter clockwise. Once
loosened 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 dissembled 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 a regenerant piston for 7-LXCTAIR and 7-LXIMAIR models).
The regenerant piston (the small diameter one behind the main piston found only the 7-LXIMAIR models is removed from the main
piston by pressing sideways and 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 dilute sodium 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. 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 a 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 that 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 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 ash the software version and then reset the
valve to the service position.

REFILL FLOW CONTROL ASSEMBLY (refer to page 7 for diagrams):
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 at blade 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.
Reset the ow control so the rounded end is visible in the ow control. Reset 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 reset 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 the
white retainer.
SPACER STACK ASSEMBLY (refer to page 12 for diagrams):
To access the spacer stack assembly remove the drive assembly, drive cap assembly and piston. The spacer stack assembly can be
removed easily without tools by using thumb and forenger. Inspect the black o-rings and clear lip seals for wear or damage. Replace
the entire stack if necessary. Do not disassemble the stack.
The spacer stack assembly may be chemically cleaned (dilute sodium bisulte or vinegar) or wiped 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 (5/8” to 1-1/8” 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 5/8”). Do not force the spacer stack assembly
in. The control valve body bore interior can be lubricated with silicone to allow for easy insertion of the entire stack.
Reattach the drive cap assembly and piston(s) and the drive assembly.
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 ash the software version and then reset the
valve to the service position.
INJECTOR CAP, SCREEN, INJECTOR PLUG, AND INJECTOR (refer to page 12 for diagram):
Unscrew the injector cap and lift off. Loosen cap with special plastic service spanner wrench (see page 16) or pliers if necessary.
Attached to the injector cap is a screen. 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 consists of a throat and a nozzle. Chemically clean the injector with vinegar or sodium bisulte. The holes can be
blown out with air. Both pieces have small diameter holes that control the ow rates of water to insure that the proper concentration
of 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.
For 7-LXCTCIR and 7-LXIMAIR models, push the plug in the hole marked “UP” and the injector in the hole marked “DN”.
For all other models, push the plugs in the holes marked “UP” and “DN”.
Replace the screen and hang tighten the injector cap.
WATER METER (refer to page 13 for diagrams):
The water meter assembly is connected to the PC board by a wire. If the entire water meter assembly is to be replaced, remove the
control valve cover and disconnect the power source and water meter plugs from the PC board. Unlatch the drive assembly and lean it
forward. Unthread the water meter wire from the side of the drive assembly and through the drive back plate. To reinstall, rethread the
water meter wire through the drive back plate and the side of the drive assembly. Reattach the drive assembly and the water meter and
power plugs.
THIS WATER METER SHOULD NOT BE USED AS THE PRIMARY MONITORING DEVICE FOR CRITICAL OR HEALTH EFFECT
APPLICATIONS.
The water meter wire does not need to be removed from the PC board if the water meter is only being inspected and cleaned. To
remove the water meter 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 water meter is visible. Twist a at blade screwdriver in the slot between the control valve
body and the meter. When the meter is part way out it is easy to remove the water meter from the housing. Once the water meter is
removed from the control valve body, gently pull forward on the turbine to remove it from the shaft.
Do not use a wire brush to clean the turbine. Wipe with a clean cloth or chemically clean in dilute sodium bisulte or vinegar. The
turbine can be immersed in the chemical. Do not immerse electronics. If the turbine is scored or damaged or the bearings on the turbine
are worn, replace the turbine.
Do not lubricate the turbine shaft. The turbine shaft bearings are prelubricated. Do not use Vaseline, oils, or other unacceptable
lubricants on the o-ring. A silicone lubricant may be used on the black o-ring.
Snap the turbine on the shaft and reinsert the water meter into the side slot. Hand tighten the nut. Do not use a pipe wrench to tighten
nut.
