Pre-installation Instructions

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 naturally occurring 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 ability to 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 pressure tanks. 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 many gallons until the pump turns back on again. This is Draw Down.
5. Calculate pumping rate by dividing draw down by cycle time and multiplying by 60.

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

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 by installing 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.

Typical Installation

Installation Instructions

STEP 1: If media is already loaded in filter tank proceed to Step 4. Otherwise, unscrew the control valve (DO NOT REMOVE THE CLAMP!) and 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 (DO NOT REMOVE THE CLAMP!). 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.
If there are any branches in the plumbing between the pressure tank and the KLX you must install the CKV-1 coupling check valve and an expansion tank (Figure 1, Page 4). See CKV-1 installation instructions on page 19.

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 Time Pointer (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.

Advance control valve to backwash position:

STEP 12: KLX2 Slowly rotate 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 will appear on the display).

STEP 13:   Unplug the control valve from the electrical outlet to keep it in the backwash position.
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 verify the unit draws air during the air draw cycle by feeling 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.

KLX2 Timer Operation

How to set Time of Day:

1. Press and hold the red button to disengage the drive gear.
2. Turn the large 24 hour gear until the actual time of day is at the time of day pointer.
3. Release the red button to again engage the drive gear.

How to set the Days of Backwash

1. Rotate the skipper wheel until the number 1 is at the red pointer.
2. Each number represents a day. The number by the red pointer is tonight.
3. Slide the metal tabs outward on the desired days of regeneration.

The KLX2 Filter should be set to backwash a minimum of every third day.

How to Manually Initiate a Backwash Cycle:

1. Grab the manual regeneration knob and turn clockwise.
2. The drive gear will engage the program wheel and make a complete revolution through the backwash cycle.
3. The backwash knob will make a complete revolution and return to the home position after the backwash cycle.

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 wheel away from micro switch arms and timer assembly.
3. RAPID RINSE cycle may be lengthened by adding pins at the end of the program wheel. Each pin represents 2 minutes of rapid rinse time. The rapid rinse time MUST only be increased by shifting both the backwash pins and air draw holes an equal number of positions counter-clockwise on the program wheel.
4. AIR DRAW cycle may be lengthened by increasing the number of holes between the two sets of pins. Each hole represents 2 minutes of air draw time. The air draw time MUST only be increased by moving 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 may be lengthened by adding pins in a counter-clockwise direction to first set of pins on program wheel. Each pin will equal 2 minutes of backwash time. Ensure that adding pins does not decrease air draw time.
6. Reinstall the program wheel on the retaining lugs by maneuvering 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.

CKV-1 Coupling Check Valve Installation

The check valve included with this unit replaces the coupling on the INLET of a water treatment unit between the bypass valve and the valve body. In units designed to maintain an air head, this check valve will prevent the loss of air when water is used prior to the water treatment unit (outside hose bibs, heat pumps, lawn irrigation, etc.).
WARNING: Installation of this check valve will prevent hot water expansion in the plumbing. An expansion tank must be used on the hot water line to allow for thermal expansion. All local plumbing codes must be followed.

INSTALLATION:

1. If the water treatment unit was previously installed, place it in bypass position and relieve the pressure from the tank. (Refer to water treatment unit manufacturer’s instructions.)

2. Remove coupling from INLET of water treatment unit. Coupling will be located between control valve and bypass valve.

3. Remove retaining clip and screw from original coupling and install on check valve coupling.

4. Install the new check valve on the INLET of the water treatment unit.
   NOTE: Pay close attention to the direction of flow arrow molded on the side of the check valve body

5. Reconnect bypass valve, turn on water and check for leaks. (Refer to manufacturer’s instructions for detailed instructions on pressurizing the water treatment unit.)
