Description of the iron filtration system
The KLX2 catalytic filtration system includes a single filtration tank with a pocket of air and a backwashing
control valve. Incoming water flows into the control valve and is directed into the filtration tank. Exposure to the
air in this tank will start oxidizing the iron which is then trapped by the media. The iron/sulfur-free water then
returns to the control valve where it is directed into the service lines.
Periodically the control valve will go through a backwash cycle. This cycle will typically begin at 1:00 A.M.
flushing the accumulated iron to the drain. Part of this backwashing process includes an air draw cycle which
will replenish the pocket of air in the filter tank and prepare the unit for the next period of service.
Water Quality
While the KLX2 filter will perform under a variety of water qualities there are a few things that need to be
considered to ensure satisfactory performance. The water should be tested to determine the concentration, or
levels of the items listed below.
pH - A measurement of the acidity of the water. pH is reported on a scale from 0 to 14. Neutral water has a pH
of 7.0, lower values indicate acidic water. The KLX2 catalytic filter performs best when the pH is 7.0, or higher.
pH values below 7.0 require a special media blend in the filter in order to elevate the pH for proper iron
oxidation.
Iron - A naturallyoccurring metallic element. Iron concentrations in excess of 0.3 milligrams/liter (mg/l) combine
with oxygen causing orange or red (rust) stains on plumbing fixtures. Iron naturally exists in some water
sources in either clear water (ferrous) state, red water (ferric) state or bacterial form. The KLX2 catalytic filter
can reduce any of these forms of iron.
Manganese - A naturally occurring metallic element. Manganese concentrations as low as 0.05 milligrams/liter
(mg/l) can combine with oxygen to cause dark brown or black staining on fixtures. Additionally, manganese can
cause an odor in the water similar to a “rotten egg” smell. The KLX2 catalytic filter reduces manganese as well
as iron, however, manganese oxidation requires the pH of the water to be elevated to 8.2 or higher.
Tannin - A naturally occurring humic acid. Tannin is an acid caused by water passing through decaying
vegetation. Coffee and Tea are prime examples of tannin in water. As hot water passes over the coffee beans,
or tea leaves, the tannin is extracted causing color and flavor in the water. Tannin concentrations as low as 0.3
milligrams per liter can cause a yellow discoloration in the water and may interfere with the KLX2 filter’s long-
term abilityto function properly as the media becomes coated with the tannic acid.
Hydrogen Sulfide - A naturally occurring gas. Hydrogen sulfide, more commonly referred to as sulfur gas,
causes a distinct odor similar to “rotten eggs.” Due to its gaseous nature, hydrogen sulfide must be tested at the
well site within 1 minute of drawing the sample. If a water sample has been sitting for a while the sulfur gas will
dissipate and cause the hydrogen sulfide test to be lower than the actual concentration. If sulfur is present, the
filter should be set to backwash more frequently to prevent the gas from building up.

Water Supply
Unlike other iron filters that do not use chemicals to oxidize the iron, the KLX2 catalytic filter does not require
additional devices such as air compressors, venturis, solenoids, pressure switches or pressuretanks. This filter
will function properly when the water supply is furnished by a jet pump (5 gpm minimum), submersible pump,
variable speed (constant pressure) pump or community water supply. As with all other filter systems, however,
it is imperative that the well pump provides enough flow rate for the filter to adequately backwash. In order to
ensure sufficient backwash flow rate the following pumping rate test should be performed prior to installing the
iron filter.
1. Make certain no water is being drawn in the house.
2. Open spigot nearest pressure tank.
3. When well pump starts, close spigot and measure time (in seconds) to refill pressure tank (well pump
turns back off). This is Cycle Time.
4. Using a container of known volume, draw water from pressure tank and measure how manygallons
until the pump turns back on again. This is Draw Down.
5. Calculate pumping rate bydividing draw down by cycle time and multiplying by 60.
Draw Down (gallons)

60

Pumping Rate (gallons per minute)
Cycle Time (seconds)
Example: Draw down is 8 gallons
Cycle time is 65 seconds
Location Considerations
The proper location to install the KLX2 filter will ensure optimum filter performance and satisfactory water
quality. The following factors should be considered in selecting the location of the iron filter.
1. The filter should be installed after the pressure tank (private well system only).
2. The filter should be installed as close as possible (preferably within 15’) to an adequate floor or
laundry drain capable of handling the backwash cycle volume and flow rate (refer to unit
specifications).
3. All water conditioning equipment should be installed prior to the water heater. Water temperatures
exceeding 100°F can damage the internal components of the control valve and filter tank. An
expansion tank may need to be installed in the line to the water heater in order to allow for thermal
expansion and comply with local plumbing codes.
4. The filter should not be subject to freezing temperatures.
5. The filter should be installed before a water softener (if required).
6. Never install a cartridge type filter prior to the KLX2 iron filter. Any cartridge or in-line filter (if
desired) should be installed after KLX2 filter. This will prevent restricting the water flow and
pressure available for backwash.
7. Appliances requiring extended periods of continuous or high flow water use (i.e. geothermal heat
pumps, swimming pools, lawn irrigation, outside hose bibs, etc.) should bypass the filter and a
spring check valve should be installed on the filter inlet to prevent backflow of air from the filter tank
(see installation diagram Fig. 1).

GENERAL INSTALLATION & SERVICE WARNINGS
The water conditioner is not designed to support the weight of plumbing.
Do not use Vaseline, oils, other hydrocarbon lubricants or spray silicone anywhere. A silicone lubricant may be
used on black “O” Rings. This will allow ease of installation and decrease chance of rolling from the bypass and
tank connections. Avoid any type of lubricants, including silicone, on red or clear lip seals.
Do not use pipe dope or other sealants on threads. Teflon®tape must be used on the threads of the drain line
connection. Teflon®tape is not used on any connection where “O” Ring seals are used
NOTE: If the plumbing system is used as the ground leg of the electric supply, continuity should be maintained
byinstalling ground straps around any non-conductive plastic piping or bypass used in the installation.
Make sure the filter is not installed backwards. The filter will not function properly if installed backwards and filter
media may be forced into the water lines. Arrows molded into the valve body and into the bypass indicate the
direction of flow.

STEP 1: If media is already loaded in filter tank proceed to Step 4. Otherwise, place red pipe cap (if
provided) or a piece of tape over the end of the distributor tube to prevent media from entering
the distributor tube during media filling. Make sure the distributor tube is centered and not
suspended off the bottom of the tank by gravel (pre-loaded).
STEP 2: Use the fill funnel provided to add the provided media to the filter tank. Do not overfill the tank.
At least 14” of freeboard (empty space) is required at the top of the media tank to allow for
proper bed expansion during backwash.
STEP 3: Clean any media out of the tank threads and remove pipe cap or tape from distributor tube.
STEP 4: If the control valve is already installed on the filter tank; unscrew the control valve. Using a
garden hose or bucket and media funnel; fill the mineral tank with water to allow the media
time to saturate.
STEP 5: Make sure control valve pilot tube and tank thread o-rings are lubricated with silicone lubricant
and screw the control valve onto the filter tank.
STEP 6: Shut off water at main supply. Relieve pressure by opening nearest faucet. On private well
systems, turn off power to pump and drain pressure tank. SHUT OFF POWER OR FUEL
SUPPLY TO WATER HEATER.
STEP 7: Cut main supply line as required to fit plumbing to inlet and outlet of bypass valve. DO NOT
PLUMB INLET AND OUTLET BACKWARDS. Piping should support control valve in an
upright position. Do not apply heat to any fitting attached to the bypass or control valve.
STEP 8: Use the provided drain line tubing (NO VINYL TUBING) to run drain line from control valve
discharge fitting to floor drain or sump pit capable of handling the backwash rate of the filter
(refer to specifications and flow rate on page 12). DISCHARGE END OF THE DRAIN LINE
MUST BE FIRMLY SECURED! Failure to properly secure the drain line will result in the drain
line “whipping” and possibly flooding the area causing water damage. There must be an air
gap at the end of the drain line to prevent siphoning of waste water and meet plumbing code.
Total length of drain line should be 15’ or less. AVOID OVERHEAD DRAINS.

STEP 9: Be sure the bypass valve is in the “BYPASS” position (see figure 3, page 4).
Plug the power cord(KLX2) or transformer (KLX2E) into a non-switched electrical outlet.
Open main supply valve or turn on power to the pump or private well system. Check for leaks
and correct as needed.
STEP 10: KLX units require you to set the current time of day by depressing the red Time Set Button
(Figure 4a) and turning the 24 Hour Gear (Figure 4a) to the desired time (note AM and PM).
For the KLX2E unit see page 11 for Setting Time of Day.
STEP 11: Time of Regeneration is factory set to 1:00 A.M. To adjust the time of regeneration on KLX2
units (if needed):
a) Unplug control valve from electrical outlet
b) Locate three screws (Figure 4b, page 6) behind the Manual Backwash Knob
(Figure 4a, Page 6) by pushing the red Time Set Button (Figure 4a, page 6) and
rotating the 24 Hour Gear (Figure 4a, page 6) until each screw appears in the cut out
portion of the Manual Backwash Knob.
c) Loosen each screw slightly to release pressure on the 24 Hour gear time plate.

d) Continue depressing the red Time Set Button and rotate the 24 Hour Gear to
expose the Regeneration TimePointer (Figure 4a, page 6) in the cut out portion of the
Manual Backwash Knob. Keep the Regeneration Time Pointer visible in the cut out
while rotating only the time plate until the desired time of regeneration (note AM and
PM) is aligned with the Regeneration Time Pointer. NOTE: subtract 136 minutes from
the desired time for the start of backwash to determine where the Regeneration Timer
Pointer should point.
e) Continue depressing the red Time Set Button and rotate the 24 Hour Gear along
with the Time Plate until each screw has been exposed in the cut out portion of the
Manual Backwash Knob and re-tightened. DO NOT OVERTIGHTEN. Make certain
that the backwashing filter DOES NOT regenerate at the same time with any other
water treatment equipment.
Time of Regeneration for KLX2E units can be changed (factory set for 1:00 AM). To change
refer to Additional Programming on page 13.
STEP 12: Advance control valve to backwash position:
KLX2 Slowlyrotate the Manual Backwash Knob (see Fig. 4a) clockwise until two clicks are
heard. This is the “BACKWASH” position.
KLX2E Press and hold down the center “ADVANCE” button until “GO TO BW” appears on
the screen (see Fig. 6, page 11). Wait until the valve reaches the backwash position before
going to STEP 11 (a countdown timer willappear on the display).
Unplug the control valve from the electrical outlet to keep it in the backwash position.
STEP 13: Refer to Figure 3 (page 4) for appropriate bypass valve operation. Rotate bypass lever of
stainless steel bypass ¼ of the way to “Service” allowing unit to fill slowly. You should hear
water trickling into the mineral tank. Filling the mineral tank in this position will force any
trapped air to the drain. When all air has been purged from the system and only water is
running to the drain, slowly open the bypass valve fully to the service position and
allow the unit to backwash until the drain water is clear of any cloudiness due to media
fines.
STEP 14: Plug the control valve back into the electrical outlet and allow it to complete the remainder of
the regeneration cycles automatically. Please verifythe unit draws air during the air drawcycle
byfeeling for suction at the end of the white check valve attached to the control valve.
STEP 15: Turn power or fuel supply back on to water heater.

How to Change the Length of Backwash Cycles:
All cycles have been factory set and should not need adjustment. If local conditions require different
cycle lengths, however, the following procedures should be followed. The end of the program wheel has been
used for backwash cycles to minimize the amount of time that pressure will be applied to the air draw check
valve.
1. Grasp top left corner of timer assembly and pull to swing timer open and expose the program
wheel.
2. Remove program wheel from timer by squeezing retaining lugs in center of program wheel.
Maneuver program wheelaway from micro switch arms and timer assembly.
3. RAPID RINSE cycle may be lengthened byadding pins at the end of the program wheel. Each pin
represents 2 minutes of rapid rinse time. The rapid rinse time MUST onlybe increased byshifting
both the backwash pins and air draw holes an equal number of positions counter-clockwise on the
program wheel.
4. AIR DRAW cycle maybe lengthened byincreasing the number of holes between the two sets of
pins. Each hole represents 2 minutes of air draw time. The air draw time MUST onlybe increased
bymoving the backwash pins counter-clockwise on the program wheel. Ensure that lengthening
the air draw time does not decrease either the backwash or rapid rinse times.
5. BACKWASH cycle maybe lengthened by adding pins in a counter-clockwise direction to first set of
pins on program wheel. Each pin willequal 2 minutes of backwash time. Ensure that adding pins
does not decrease air draw time.
6. Reinstall the program wheel on the retaining lugs bymaneuvering past the micro switch arms.
7. Close and latch the timer assembly. Ensure that the retainer snaps into the hole in the backplate
and all electrical wiring is ABOVE the timer post.

PROBLEM
CAUSES
SOLUTIONS
Excessive pressure
drop through filter
A) Filter not
backwashing
B) Filter bed loaded
with sand
C) Insufficient
backwash
D) “Cementing” or
“Channeling”
E) Control Valve
plugged with debris
1) Check timer motor or control board and
replace if faulty
2) Ensure uninterrupted power supply
3) Check Backwash frequency setup
4) Verify sediment being removed is less
dense than the filter media and install a
“Spin-Down” type sediment filter ahead of
the filter to remove wellsand
5) Increase frequencyof backwash
6) Increase length of backwash and rinse
cycles
7) Verify adequate pumping rate for backwash
8) Probe media bed to check for “Cementing”
9) Check drain line for restriction: frozen,
plugged, kinked, exceeds 15’, overhead
installation, flexible drain line, drain line
diameter too small
10) Disassemble and clean control valve
Water is colored
from the tap
A) Leaking bypass
valve
B) Internal valve leak
C) Distributor not
seated properly in
control valve
D) Water usage flow
rate exceeds filter
specifications
E) Insufficient
backwash
1) Verify bypass valve is in service position
and inspect seal, replace if needed
2) Replace spacers and seals
3) Verify distributor tube seated securely in
control valve body
4) Verify actual water usage flow rates against
system specifications
5) Verify adequate pumping rate for backwash
6) Increase frequencyof backwash
7) Increase length of backwash and rinse
cycles
Clear water turns
colored after drawn
A) Insufficient air draw
B) Plugged injector or
injector screen
C) Open or leaking
bypass valve
D) pH too low
1) Verifyair draw check valve is functioning
properly and replace if needed
2) Check drain line for restriction: frozen,
plugged, kinked, exceeds 15’, overhead
installation, flexible drain line, drain line
diameter too small
3) Verify adequate pumping rate for backwash
4) Increase air draw time
5) Remove and clean injector & screen
6) Verify bypass valve is in service position
and inspect seal, replace if needed
7) Test pH. Must be 7.0 or higher or 8.2 or
higher if Manganese is present
(also see next troubleshooting section)
KLX media fails to
raise pH sufficiently
A) Water usage flow
rate is too high to
provide adequate
contact time
B) Additional steps are
needed to effectively
raise pH
1) Verify actual water usage flow rates against
system specifications
2) Install a chemical feed pump system ahead
of the filter with Soda Ash
