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.
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
IBW/IMBW.
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)
X
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 IBW/IMBW will ensure optimum filter performance and satisfactory water
quality. The following factors should be considered in selecting the location of this system.
1. The IBW/IMBW 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 IBW/IMBW 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 mayneed 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 electricityfrom an outlet that is not wired to a switch.
7. Never install a cartridge type filter prior to the IBW/IMBW. Any cartridge or in-line filter (if desired)
may be installed after the IBW/IMBW 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.

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
The nuts and caps are designed to be unscrewed or tightened byhand or with the special plastic Service
Wrench, (CV3193, not included). If necessarypliers can be used to unscrew the nut or cap. Do not use a pipe
wrench to tighten nuts or caps. Do not place screwdriver in slots on caps and/or tap with a hammer.
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 red handles of the bypass
indicate the direction of flow.

The bypass valve is used to isolate the control valve from the plumbing system's water pressure in order to
perform control valve repairs or maintenance. The 1" full flow bypass valve incorporates four positions including
a diagnostic position that allows a service technician to have pressure to test a system while providing untreated
bypass water to the building. Be sure to install bypass valve onto main control valve, before beginning plumbing
or make provisions in the plumbing system for a bypass. The bypass body and rotors are glass filled Noryl®
and the nuts and caps are glass filled 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 direction of flow. The plug valves enable the bypass valve to operate in four
positions.
1. Normal Operation Position: The inlet and outlet handles point in the direction of flow
indicated by the engraved arrows on the control valve. Water flows through the control
valve for normal operation of a water softener or filter. During the regeneration cycle this
position provides regeneration water to the unit, while also providing untreated water to
the distribution system (Fig. 2).
2. Bypass Position: The inlet and outlet handles point to the center of the bypass. The
system is isolated from the water pressure in the plumbing system. Untreated water is
supplied to the building (Fig. 3).
3. Diagnostic Position: The inlet handle points toward the control valve and the outlet
handle points to the center of bypass valve. Untreated supply water is allowed to flow to
the system and to the building, while not allowing water to exit from the system to the
building (Fig. 4) .This allows the service technician to draw brine and perform other tests
without the test water going to the building.
NOTE: The system must be run through a rinse cycle before returning the bypass valve
to the normal position.
4. Shut Off Position: The inlet handle points to the center of the bypass valve and the outlet
handle points away from the control valve. The water is shut off to the building. The water
treatmentsystem will depressurize upon opening a tap in the building. A negative pressure
in the building combined with the softener being in regeneration could cause a siphoning
of brine into the building. If water is available on the outlet side of the softener it is an
indication of water bypassing the system (Fig. 5)

STEP 1: Unpack filter unit, making sure to remove entire contents of the shipping container prior to
disposal.
STEP 2: With the 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) (purchased separately) 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.
IMPORTANT: Carbon, Filter Ag, Zeolite 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.
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: 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 TOWATER HEATER.
STEP 7: Plumb the water supply line to the unit's bypass valve inlet, located at the right rear as you
face the unit. There are a variety of installation fittings available. They are listed under
Installation Fitting Assemblies, pages 21-22. When assembling the installation fitting package
(inlet and outlet), connect the fitting to the plumbing system first 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 solder flux, primer, and solvent cement on any part
of the "O" Rings, split rings, bypass valve, or control valve. If the building's electrical system is
grounded to the plumbing, install a copper grounding strap from the inlet to the outlet pipe.
Plumbing must be done in accordance with all applicable local codes. MAKE CERTAIN
WATER ENTERS THROUGH INLET AND DISCHARGES THROUGH OUTLET.

STEP 8: Apply thread tape to DLFC Assembly. Remove drain line flow control (DLFC) retainer clip
(Figure 6, Page 6) and remove the DLFC assembly from the valve body, (Figure 6, Page 6).
Unscrew drain line elbow from DLFC. Apply thread tape to threads and re-attach the barbed
drain line elbow(not shown). Reinsert DLFC assemblyinto the valve body, making certain it is
FULLY inserted before replacing the retaining clip.
STEP 9: Install drain line (included). Use polyethylene tubing provided (NO VINLY TUBING) to run
drain line from control valve to floor drain, laundry drain or sump pit capable of handling the
backwash rate of the filter (refer to specifications and flow rate on page 16) or discard the
barbed fitting and use ¾” NPT fitting to connect a rigid pipe drain line (recommended). If
backwash flow rate is greater than 7 gpm or drain line length exceeds 15’, use ¾” rigid pipe for
drain line. There must be an air gap at the end of the drain line to prevent siphoning of waste
water. AVOID OVERHEAD DRAINS AND DRAIN LINE LONGER THAN 15’.
STEP 10: MAKE SURE THE BYPASS VALVE IS IN THE “BYPASS” POSITION (Figure3, Page 5)
NOTE: the INLET and OUTLET knobs turn clockwise to close the port to the softener and
counter-clockwise to open the port to the softener. Open the main supply valve or turn on
power to the pump on private well systems. Check for leaks andcorrect as needed
STEP 11: Pressurize the filter. Gradually turn the INLET side knob of the bypass valve counter-
clockwise ONLY ½ way (45 degrees) to the “Service” position (Figure 2, Page 5) allowing unit
to pressurize slowly. Check for leaks and correct as needed
STEP 12: Program control valve. Plug the transformer of the control valve into an uninterrupted
electrical outlet (not wired to a switch) and use the buttons on the front of the control valve to
adjust the initial settings:

1. General Operation:
When the system is operating, one of the three displays maybe shown. Pressing next will alternate
between displays. One of the displays is always the current time of day. The second display shows
the current treated water flow rate through the system in Gallons Per Minute (gpm). NOTE: the
Gallons Per Minute display will always show 0.0 because there is no meter to detect flow in the
IBW/IMBW. The third displayshows the current days remaining before regeneration.
The user can scroll between the displays as desired.
If the system has called for a regeneration that will occur at the preset time of regeneration, the words
REGEN TODAY will appear on the display.
2. Regeneration Mode:
Typically a system is set to regenerate at a time of no water use. If
there is a demand for water when the system is regenerating,
untreated water will be delivered. When the system begins to
regenerate, the display will change to include information about the
step of the regeneration process and the time remaining for that
step to be completed. The system runs through the steps
automatically and will reset itself to provide treated water when the
regeneration has been completed.
3. Manual Regeneration:
Sometimes there is a need to regenerate before the control valve calls for it. This may be needed if a
period of heavy water use is anticipated or when experiencing excessive pressure drop.
To initiate a manual regeneration at the
preset delayed regeneration time, press
and release regen. The words “REGEN
TODAY” will flash on the display to
indicate that the system will regenerate at
the preset delayed regeneration time.
If you pressed the regen button in error,
pressing the button again will cancel the
command.
To initiate an immediate manual regeneration, press and hold the regen button for
three seconds. The system will begin to regenerate immediately. This command
cannot be cancelled.
4. Power Loss:
If the power goes out for less than two hours, the system will
automaticallyreset itself. If an extended power outage
occurs, the time of day will flash on and off which indicated
the time of day should be reset. The system will remember
all other settings.
Error Message: If the word “ERROR” and a number are
alternately flashing on the display, record the number and contract the dealer for help. This indicates
that the control valve was not able to function properly.

1) If your unit contains activated carbon, you should 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 frequencyof backwashing.
2) 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 frequencyof backwashing or if water
quality diminishes due to contaminant bleed through.
3) Neutralizer media or calcite must be replenished at least annually. Mark the side of the mineraltank at
installation so the drop in media levelmay be monitored by shining a bright light behind the mineral
tank. Add media if the level has dropped by more than three inches.
4) Birm should be replaced when iron reappears in the treated water and backwashing does not improve
the water quality.
TO REPLENISH OR REBED MEDIA:
1) Pressure must be relieved on the system by placing the Bypass Valve in the “Bypass” position (Figure
3, Page 5) and initiating a manual regeneration (section 3, page 10).
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 the 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.
9) (IF REBEDDING ONLY! 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 valve (Figure 6, Page 6) to control valve body.
12) Reattach Drain Line to Control Valve (Figure 6, Page 6).
13) IMPORTANT! Activated Carbon, Filter Ag, Zeolite 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) Gradually turn the INLET side knob of the bypass valve counter-clockwise ONLY ½ way (45 degrees)
to the “Service” position (Figure 2, Page 5) allowing unit to pressurize slowly. Check for leaks and
correct as needed Any air trapped in the media bed should begin purging to the drain and water
should begin flowing to the drain.
15) Once the air is purged, gradually turn the INLET knob of the bypass valve counter-clockwise until it is
fully in “Service” position (Figure 2, Page 5). Then turn the OUTLET knob of the bypass valve counter-
clockwise until it is fully in the “Service” position (Figure 2, Page 5). 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 transformer into the electrical outlet. Press the “REGEN” button to advance the control valve
to the “RINSE” cycle. Another count-down timer will appear in the time-of-day position, “RINSE” will be
shown in the lower middle of the display and “REGEN” appears in the middle left of the display. Allow
the rinse cycle to complete and the filter will return to servicemode automatically.
