Description of the backwashing filter

The FBW system includes a filtration tank (with gravel and distributor) and a backwashing control valve with bypass. Filtration media for use with the FBW system is purchased separately and selected from the following types:

The FBW ARSENIC system includes a filtration tank (with gravel and distributor), arsenic reduction media (shipped separately) and a backwashing control valve with bypass. The media is included with the unit for FBW ARSENIC unit only.

Pre-installation Instructions (cont.)

Successful Application

Any filter media may have specific limitations and/or requirements for successful application. A water sample should be submitted to First Sales for analysis and recommendation by Customer Service.

FBW ARSENIC IMPORTANT: Contact First Sales technical services to assist with proper sizing based on the level of arsenic in the water and the flow rate requirement. The arsenic test results must be from a certified laboratory to ensure accuracy. Other water quality information is required as well, and will determine if pre-treatment equipment is required to meet the influent water quality pre-requisites for the FBW ARSENIC system: Iron < 0.3 ppm, Manganese < 0.05 ppm, pH < 8.0, Silica < 30 ppm, Hardness > 5 gpg is preferred but not required.

Once the system has been installed, an arsenic test should be done to determine if the arsenic level is being reduced sufficiently (10 ppb or less, per the EPA MCL) and should be tested regularly (every 6 months recommended) to ensure the system is functioning properly and to indicate when the media has become exhausted.

Time of Backwash

Periodically the control valve will go through a backwash cycle. This cycle is factory preset to 12:00 A.M. flushing the accumulated sediment and/or precipitant to the drain. After the backwashing process the unit is now prepared for the next period of service.

Water Supply

This filter will function properly when the water supply is furnished by a jet pump, 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 FBW or FBW ARSENIC system.

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.

Example: Draw down is 8 gallons

Cycle time is 65 seconds

Location Considerations

The proper location to install the FBW/FBW ARSENIC will ensure optimum filter performance and satisfactory water quality. The following factors should be considered in selecting the location of this system.

1. The FBW/FBW ARSENIC must be installed after the pressure tank (private well system only).

2. The system 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). An air gap should be provided between the FBW drain line and plumbing drain.

3. All water conditioning equipment should be installed at least 10’ 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. Water pressure must not exceed the range of 25 - 100 psi.

5. The system must not be subject to freezing temperatures.

6. The control valve requires 115/120 V, 60 Hz electricity from a three prong outlet that is not wired to

a switch.

7. Never install a cartridge type filter prior to the FBW/FBW ARSENIC. Any cartridge or in-line filter (if

desired) may be installed after the FBW/FBW ARSENIC system. This will prevent restricting the water flow and pressure available for backwash.

8. 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.

Typical Installation

Installation Instructions

FIGURE 2: Top View of Control Valve

STEP 1: Unpack FBW/FBW ARSENIC filter unit, making sure to remove entire contents of the shipping

container prior to disposal.

STEP 2: With the FBW/FBW ARSENIC filter unit in the upright position, remove the control valve from

the mineral tank being careful to not pull the distributor out of the gravel at the bottom of

the tank.

STEP 3: Cover the top of the distributor tube with the included red cap and, using the included blue

media funnel, pour filter media(s) into the mineral tank. If using multiple filter media types, load in the order of heaviest (most dense) to lightest (least dense). 12” – 14” of space MUST be left empty at the top of the mineral tank to allow for media bed expansion during backwash and to

prevent filter media from being discharged through the drain line.

STEP 4: Use a garden hose or bucket to fill the media tank with water. STEP 5: Clean mineral tank threads to remove any filter media. Remove red cap from distributor tube

and reinstall control valve by threading it securely onto the mineral tank. (O-ring seal; HAND

TIGHTEN ONLY!).

STEP 6: Use clips and screws provided and attach bypass valve to the inlet/outlet of the control valve.

See Figure 2 below.

STEP 7: Shut off all water at main supply. On private well system, turn off power to pump and drain

pressure tank. Make certain pressure is relieved from complete system by opening nearest faucet to drain system. SHUT OFF FUEL / ELECTRICAL SUPPLY TO WATER HEATER.

STEP 8: 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 be supported. Do not apply heat

to any fitting attached to the bypass or control valve. Perform all plumbing according to local plumbing codes.

STEP 9: Attach plumbing. DO NOT apply heat to any fitting connected to bypass valve or control valve,

as damage may result to internal parts or connecting adapters. MAKE CERTAIN WATER ENTERS THROUGH INLET AND DISCHARGES THROUGH OUTLET.

Installation Instructions (cont.)

FIGURE 3: Stainless Steel Bypass Valve Operation

STEP 10: Use polyethylene drain line tubing provided (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! 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 11: Place bypass in the “Bypass” position (refer to Figure 3 below). Open main supply valve or turn

on power to pump on private well systems.

STEP 12: Plug the power cord into an un-switched electrical outlet. STEP 13: Initiate a manual regeneration by turning the Manual Backwash Knob clockwise until the knob

engages the program wheel. You should hear one click. This is the “Backwash” position. Then, unplug the control valve from the electrical outlet to prevent it from advancing automatically.

STEP 14: Refer to Figure 3 (page 6) for appropriate bypass valve operation. Rotate bypass lever of

stainless steel bypass ¼ of the way to Service or until air and/or water begins to flow slowly to drain.

Page 8

Installation Instructions (cont.)

STEP 15: IMPORTANT: Activated Carbon, Filter Ag and Birm must be soaked for at least 2 hours

prior to submitting it to full flow rate to prevent loss of media to drain. Once the air is

purged, fully open the bypass valve to the “Service” position (Figure 3, Page 4) and leave the

control valve in “Backwash” position for at least 10 minutes or until water flowing from the drain

line runs clear; whichever is longer.

STEP 16: Plug the power cord back into an un-switched electrical outlet.

Manually advance the control valve to the “Service” position (Figure 4a) by turning the Manual Backwash Knob clockwise and reconnect the control valve to the electrical outlet. Check for and resolve any leaks in the unit or connected plumbing.

STEP 17: Set the Timer Control (Figure 4a) by rotating the Skipper Wheel (Figure 4a) so the red pointer

is directly over day 1. Select the days when backwashing will occur by sliding the metal tabs in or out. IN indicates no backwashing will occur on that day, OUT indicates that backwashing will occur on that day. Factory setting is to initiate backwash every third day.

IMPORTANT: Raw water quality determines the frequency of backwashing required. It is recommended that the unit be backwashed NO LESS THAN every 6 days. If pressure drop increases or contaminants are detected in the filtered water, backwashing frequency MUST be increased. Filters with Calcite or Neutralizer media should be backwashed AT LEAST EVERY OTHER DAY to prevent the media particles from “cementing” together.

STEP 18: 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).

STEP 19: Time of Regeneration is factory set to 12:00 A.M. To adjust the time of regeneration:

a) Unplug control valve from electrical outlet. b) Locate three screws (Figure 4b) behind the Manual Backwash Knob (Figure 4a) by

pushing the red Time Set Button (Figure 4a) and rotating the 24 Hour Gear (Figure 4a) until each screw appears in the cut out portion of the Manual Backwash Knob.

c) Loosen each screw slightly to release the pressure on the time plate of the 24 Hour Gear

d) Continue depressing the red Time Set Button and rotate the 24 Hour Gear to expose the Regeneration Time Pointer (Figure 4a) 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.

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.

STEP 20: Turn on fuel/electrical supply to water heater. RECOMMENDED: Retain the red distributor cap and blue media funnel for future replenishment of filter media. NOTE: If the FBW filter is loaded with any self-sacrificing media like Calcite or Neutralizer, mark the

media level on the side of the tank by shining a bright light through the tank to see its level. Replenish the media in the mineral tank when the level drops by more than three inches.

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.

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.

FIGURE 6: Back of Timer Assembly

Timer Operation (cont.)

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.

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. BACKWASH cycle may be lengthened by adding pins to 1st set of pins on program wheel. Each

pin will equal 2 minutes of backwash time. The remaining two sets of pins MUST also be

shifted clockwise to ensure 2 holes separate each cycle.

4. RAPID RINSE cycle may be lengthened by adding pins to the 2nd set of pins on the program

wheel. Each pin represents 2 minutes of rapid rinse time. The last set of pins MUST also be shifted clockwise to ensure 2 holes separate each cycle.

5. Reinstall the program wheel on the retaining lugs by maneuvering past the micro switch arms.

6. Close and latch the timer assembly. Ensure that the retainer snaps into the hole in the back plate

and all electrical wiring is ABOVE the timer post.

Page 11

Maintenance

1) At least every six months you should check the time of day setting. Power outages will cause the units time clock to be inaccurate and backwashing will not occur at the planned time.

2) If your unit contains activated carbon, you must replace the carbon and gravel underbed at least every three years. Replacement may be required sooner if the taste and odor being removed begins to reappear in the treated water or you experience increasing pressure drop that is not resolved by increasing the frequency of backwashing.

3) Filter Ag and Filter Sand will last indefinitely. It may be necessary to replace them if you experience increasing pressure drop that is not resolved by increasing the frequency of backwashing or if water quality diminishes due to contaminant bleed through.

4) Neutralizer media or calcite must be replenished at least annually. Mark the side of the mineral tank at installation so the drop in media level may be monitored by shining a bright light behind the mineral tank. Add media if the level has dropped by more than three inches.

5) Birm should be replaced when iron reappears in the treated water and backwashing does not improve the water quality.

6) For the FBW ARSENIC test the treated water for arsenic every 6 months to ensure the system is

functioning properly and to identify when the arsenic reduction media has become exhausted. Satisfactory test results will be 10 ppb of arsenic or less. If unsatisfactory the filter will need to be rebedded.

TO REPLENISH OR REBED MEDIA:

1) Pressure must be relieved on the system by placing the bypass valve in the “Bypass” position (Figure

3) and rotating the manual backwash knob (Figure 4a) clockwise until the knob engages the program wheel and water flows briefly to drain. Once water has stopped flowing to drain move on to next step.

2) Unplug the control valve from the electrical outlet to prevent it from advancing automatically.

3) Disconnect the control Valve from the bypass valve

4) Disconnect the drain line from the control valve

5) Unscrew control valve from mineral tank (IF REBEDDING ONLY - remove the distributor).

6) Siphon water from mineral tank (IF REBEDDING ONLY - Remove existing media and gravel).

7) IF REBEDDING ONLY - Rinse mineral tank and replace distributor, making certain that the

distributor basket sits in the center of the tank bottom.

8) Cover the top of the distributor tube to prevent media entering the tube during filling. Using a funnel, pour filter media(s) into the mineral tank. (IF REBEDDING ONLY - Begin loading tank with the

gravel underbed. Filling the mineral tank 1/3 with water before loading gravel will cushion the fall and ensure even distribution of the gravel and media. If using multiple filter media types, load in the order of heaviest {most dense} to lightest {least dense}.) 12” – 14” of space MUST be

left empty at the top of the mineral tank to allow for media bed expansion during backwash and to prevent filter media from being discharged through the drain line.

Page 12

Maintenance (cont.)

9) Use a garden hose or bucket to fill the media tank with water.

10) Clean mineral tank threads to remove any filter media. Uncover distributor tube and reinstall control valve by threading it securely onto the mineral tank. (O-ring seal: HAND TIGHTEN ONLY!)

11) Attach bypass (Figures 2 & 3) to control valve body.

12) Re-attach drain line to control valve.

13) IMPORTANT: Activated Carbon, Filter Ag and Birm must be soaked for at least 2 hours prior to submitting it to full flow rate to prevent loss of media to drain.

14) Open the bypass valve only 1/4 of the way to the “Service” position (Figure 3, Page 4). Any air trapped in the media bed should begin purging to the drain and water should begin flowing slowly to the drain.

15) Once the air is purged, fully open the bypass valve to the “Service” position (Figure 3, Page 4) and leave the control valve in “Backwash” position for at least 10 minutes or until water flowing from the drain line runs clear; whichever is longer.

16) Plug the power cord back into an un-switched electrical outlet.

17) Manually advance the control valve to the “Service” position (Figure 4a) by turning the Manual Backwash Knob clockwise. Check for and resolve any leaks in the unit or connected plumbing.

A) Filter is brand new B) Wrong media used

1) Turn bypass valve very slightly to the

“Bypass” position allowing a small

amount of untreated water to bleed into the treated water

2) Rebed the unit with a less aggressive media

Neutralizer media fails

to raise pH sufficiently

A) Water usage flow

rate is too high to provide adequate contact time

B) Media bed is

“Cemented” or

“Channeled”

1) Verify actual water usage flow rates against system specifications

2) Verify adequate pumping rate for backwash

3) Check drain line for restriction: frozen, plugged, kinked, exceeds 15’, overhead installation, flexible drain line, drain line diameter too small

Birm Filter fails to

remove iron

A) pH too low B) Dissolved oxygen

level too low

1) pH of untreated water must be 6.8 or higher – adjust with proper equipment

2) Aerator may be installed prior to the filter

Loss of media

to drain

A) Air in system B) Insufficient soak

time before first backwash after installing media

1) Ensure well system has proper air elimination control

2) Check media level and adjust if necessary

Howling or whistling

noise during

regeneration

A) Inadequate drain

line diameter or drain line restricted

1) Reconfigure or replace drain line
