System Specifications
Birm Filter
The birm filter contains media which removes soluble and precipitated iron without the use of chemicals. Periodic backwashing
cleans the bed.
Caution: These water filters are not intended to be used for treating water that is microbiologically unsafe or of unknown quality without
adequate disinfection before or after the system.
How The System Works
The chemical free iron filter consists of two major components which are:
1. An air injector, located between the pump and the pressure tank, adds a small amount of air to the iron-laden water
whenever the well pump runs. Refer to Figs. 1, 2 or 3 for its location.
2. A backwashing type filter containing a special media that causes the iron in the “Air Charged” water to precipitate throughout
the filter bed (rather than on the surface as in chemical oxidizing filters).
Your filter is factory set to backwash at 1:00 a.m.(can be adjusted as requested by customer) during a period of little or no water
use. The backwash cycle lasts approximately 15 minutes, after which filtered water service is restored. While backwashing is
taking place raw water automatically bypasses the filter if required. If possible, avoid using water during backwashing to prevent
iron-laden water entering your household plumbing system.
This valve is controlled with simple, user-friendly electronics displayed on a LCD screen. The main page displays the current time
and the remaining gallons in meter mode or the remaining days in calendar clock mode.

System Initialization
When power is supplied to the control, the screen will display TIME OF DAY AND DEFAULT GALLON SETTING. If the valve is not in
service it will read “CANATURE” while the valve returns to the service position.
Mixed Regeneration Option
This is an option that can be used on filtration units. This will enable the unit to be set for gallons between regenerations with a
frequency of days as an override to ensure the media bed stays in optimal working order.
Control Operation During A Power Failure
In the event of a power failure, the valve will keep track of the time and day for 48 hours. The programmed settings are stored in
a non-volatile memory and will not be lost during a power failure. If power fails while the unit is in regeneration, the valve will
return to the service position once power is restored. If the valve misses a scheduled regeneration due to a power failure, it will
queue regeneration at the next regeneration time once power is restored.

Manual Regeneration (Delayed or Immediate)
If you run out of filtered water because of inadequate regeneration frequency, inadequate reserve capacity, power failure or
unusually high water usage, you can initiate a manual regeneration. The filter will now automatically complete a regeneration
cycle and return to service. If possible, avoid water use during the regeneration cycle.
Once you have set your filter you may experience frequent loss of water pressure, you may have to increase the frequency of
regeneration by decreasing the number of gallons between regeneration.
If screen is locked, press “ MENU”for 3 seconds to unlock. To initiate an immediate regeneration, press the SET / REGEN button
for 3 seconds, an option for delayed or immediate regeneration will appear. Press the SET / REGEN button again and delayed will
begin flashing, press the down arrow button to have immediate flash, press the SET / REGEN button and then press the menu
button and the valve will immediately start into manual regeneration.
To initiate a delayed regeneration, press the SET / REGEN button for 3 seconds, then press the menu button and a regeneration
will be queued to the next pre-set regeneration time (2:00 a.m.).
Sizing Requirements
Water Pressure
The water system must have a pump big enough to deliver the recommended backwash rate with a minimum pressure at the inlet
of the filter of 20 psi. If the existing system cannot do this, it must be upgraded to do so. Your chemical free iron filter system is
designed to operate under normal water pressures from 25 psi to 50 psi.
NOTE: This system is not compatible with constant pressure or variable speed pumps a cycle time is required for it to work
correctly.

7
CHECK YOUR WATER PRESSURE AND PUMPING RATE
Two water system conditions must be checked carefully to avoid unsatisfactory operation or equipment damage:
1. Minimum water pressure required at the filter tank inlet is 25 psi. If pressure is over 50 psi, a pressure reducing valve must
be installed in the water supply line ahead of the hydro-charger (Fig. 1, 2 or 3).
2. The pumping rate of your well pump must be at least 5 gallons per minute (gpm) for satisfactory operation of the
aircharger. In addition, the pumping rate must equal the required backwash flow rate of your model (see below for
backwash flow rates). To measure the pumping rate of your pump, follow these instructions:
a. Make certain no water is being drawn. Open spigot nearest pressure tank. When pump starts, close spigot and
measure time (in seconds) to refill pressure tank (when pump shuts off). This figure represents cycle time.
b. With the pressure tank full, draw water into a container of known volume, and measure the number of gallons drawn
until the pump starts again. This is draw-down. Divide this figure by cycle time and multiply the result by 60 to arrive
at the pumping rate in gallons per minute (gpm). To aid in your calculation, insert the date in the following formula:
DRAW-DOWN ______ ÷ CYCLE TIME _______ x 60 = PUMPING RATE ________ (gals) (secs.) (gpm)
EXAMPLE: CYCLE TIME is 53 seconds; DRAW-DOWN is 6 gals.; then, PUMPING RATE equals:
6 gals. ÷ 53 seconds x 60 = 6.8 gpm
See chart on page two for minimum flow rates.
NOTE: If your pumping rate is inadequate, do not install your filter until problem is corrected.
Backwash Flow Rates
The most important criteria in sizing a filter is the capacity of the pump. The water must pass through the filter media at a service
flow rate that allows it to operate properly. The filter must also be backwashed at a flow rate sufficient to dislodge and remove
captured particulates. Failure to provide sufficient water will cause a build-up of particulates in the filter media, impairing its
filtration ability. In order for your filter to backwash and rinse properly, your pump must be capable of providing the backwash
flow rates indicated in the above specification chart.
Backwash Frequency
NOTE: Add one person if you have a dishwasher.
How to calculate gallons of water between regenerations
ppm of capacity between regenerations
÷ ppm of iron in the water sample
= number of gallons supplied between regenerations
- reserve capacity (number of people x 75 gallons)
EXAMPLE: 6,000 ppm between regenerations
÷ 4 ppm of iron - 4 is the minimum setting of compensated iron [To be entered by the user]
= 1,500 gallons between regenerations
–375 gallons reserve capacity (5 people x 75 gallons)
= 1,125 GALLONS - BETWEEN REGENERATIONS
How to calculate number of days between regenerations

8
Total amount of iron to be removed between regenerations -
÷ ppm of iron to be removed per day
= NUMBER OF DAYS BETWEEN REGENERATIONS
EXAMPLE: 5 people in the household
x 75 gallons of filtered water per person
= 375 gallons of filtered per day
x 4 ppm of compensated iron - 4 is the minimum setting of compensated iron
= 1,500 PPM OF IRON TO BE REMOVED PER DAY
6,000 ppm capacity ÷ 2 to ensure adequate reserve capacity
÷ 1,500 ppm to be removed per day
= 4 DAYS BETWEEN REGENERATIONS
Before Installation
INSPECTION AND HANDLING
Inspect the equipment for any visible shipping damage. If damaged, notify the transportation company and request a damage
inspection. Damage to cartons should also be noted. Handle the filter unit with care. Damage can result if dropped or if set on
sharp, uneven projections on the floor. Do not turn the filter unit upside down.
NOTE: If a severe loss in water pressure is observed when the filter unit is initially placed in service, the filter tank may have
been laid on its side during transit. If this occurs, manually backwash the filter to “reclassify” the media.
IRON (Fe)
Iron concentrations as low as 0.3 ppm will cause staining. The iron concentration, together with the flow rate demand and the
consumption rate of the water determines the basic size filter system. The higher these factors are, the larger the required
system. The Filter system is capable of filtering out the three main types of iron found in water supplies: Soluble iron (also known
as “clear water” or ferrous iron), precipitated iron (also known as “red water” or ferric iron) and bacterial iron (also known as iron
bacteria). There is no apparent upper limit of iron concentration for the filter, but special care must be taken when selecting a
filter model if your water has a combination of high iron, very low pH and/or manganese.
MANGANESE (Mn)
The presence of manganese can be bothersome, even for a chemical free iron filter. As little as 0.05 ppm of manganese can
produce a brownish or black stain. If manganese is present in your raw water consult your Independent Water Tech
representative for further recommendations.
pH
The pH of water measures its acidity or its alkalinity. Water with a pH of less than 7.0 is acidic, above 7.0 it is alkaline, and a pH of
7.0 is neutral. The lower the pH value is below 7.0 the greater the acidity, and the higher the pH value is above 7.0 the more
alkaline. Acidic water (pH less than 7.0) is corrosive to pipes, appliances, etc. A pH of 7.0 or higher facilitates iron removal If the
PH of your raw water is below 7.0 please contact your Independent Water Tech representative for further recommendations.
TANNINS (Humic Acid)
Tannins (also known as humic acid) which are present in some water supplies, are the result of decaying vegetable matter. If the
tannin concentration is above approximately 0.5 ppm, it will form a sticky coating on the media, thus rendering it incapable of
filtering the iron. A chemical free iron filter is not recommended under this condition. If the tannin concentration is less than 0.5
ppm, a chemical free iron filter may be installed however the life expectancy of the media bed will be shortened due to the tannin
coating the media.

9
HYDROGEN SULFIDE (H2S)
Hydrogen sulphide (often referred to as “sulphur”), is easily detectable by its objectionable “rotten egg” odour. Sulphur corrodes
iron, brass, copper and silver. A chemical free iron filter is not recommended when hydrogen sulphide is present. Please contact
your Independent Water Tech representative for further recommendations.
LOCATE WATER CONDITIONING EQUIPMENT CORRECTLY: (see drawings page 9)
Select the location of your filter tank with care. Various conditions which contribute to proper location are as follows:
1. Locate as close as possible to water supply source.
2. Locate as close as possible to a floor or laundry tub drain.
3. Locate in correct relationship to other water conditioning equipment.
4. Filters and softeners should be located in the supply line before the water heater. Temperatures above 120°F damage
filters and softeners, and will void the factory warranty.
5. Do not install a filter or softener in a location where freezing temperatures occur. Freezing may cause permanent damage
to this type of equipment, and will void the factory warranty.
6. Allow sufficient space around the unit for easy servicing.
THE IMPORTANCE OF YOUR PRESSURE TANK
The pressure tank found on private well systems becomes an integral part of the filter system by providing necessary mixing and
“contact time” to the “Air-Charged” water. While the iron filter will perform better on a standard water to air pressure tank, it will
perform satisfactorily on a captive air (bladder) type pressure tank. The bladder type requires more careful adjustment of the Air-
Charger and the careful location of the air relief valve. If cycle time on pumping system is less than 30 seconds and under severe
operating conditions (low pH, high iron, manganese, and small concentrations of sulphur), a standard air-to-water type pressure
tank with an air-relief valve must be used (if a bladder type tank is already in place —do not remove it —install the air-to-water
pressure tank between the Air-Charger and the bladder type tank).
NOTE: If your pressure tank (or any part of the water system) is not functioning properly, corrective action must be taken
before installation of your iron filter.

1. Locate the filter tank close to a drain where the system will be installed. The surface should be clean and level.
2. Shut off all water at main supply. On a 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 the system. Shut off fuel supply to water heater.
3. Cut main supply line as required to fit the Air injector in the plumbing between well pump and pressure tank (Air injector may
installed in a vertical or horizontal position). Be certain that the direction of flow arrow on the Air injector points toward
pressure tank and pressure control switch is located on the pressure tank side of the Air injector (rapid cycling of the pump
may occur if pressure switch is located on the well side). If check valves are used, they should be installed before the Air
injector, not between the Air injector and the pressure tank.
4. NOTE: It is advisable to install the Air injector with unions at both ends to facilitate removal and inspection. On badly scaled
older pumping systems, it may be advantageous to install an optional "y" strainer ahead of the Air injector to prevent plugging
the injector nozzle with scale.
5. Cut the main supply line as required to fit plumbing to the control valve with bypass.
6. Solder or solvent weld plumbing. Do not apply heat to any fitting connected to the control valve as damage may result to the
internal parts. Check to be certain water supply pipe is connected to the control valve inlet fitting and pipe connected to
control valve outlet fitting is in direction of house service.
7. Perform all plumbing according to local plumbing codes.
8. Use a ½” minimum pipe or tubing size for the drain line (not to exceed 10 ft 3M).
9. Use a ¾” pipe or tubing for backwash flow rates that exceed 7 gpm or length that exceeds 10ft (3 M)
NOTE: If the installation is to be split-streamed prior to the filter tank or is a public water supply installation, refer to
special instructions.
Any solder joints near the valve must be done before connecting any piping to the valve. Always leave at least 6"
(152 mm) between the valve and joints when soldering pipes that are connected to the valve. Failure to do this
could cause damage to the valve.
10.If the valve is not installed on the tank, cut the 1”central pipe flush with top of each tank. Lubricate the large o-ring
on the valve that seals against the tank. Screw the valve on to the tank. Be careful to not cross thread the valve into
the tank. Only use silicone lubricant.
11.Connect the drain line to the valve.
12. Place unit in the bypass position.
13.Slowly turn on the main water supply.
14.At the nearest cold treated water tap remove the faucet screen, open the faucet and let water run a few minutes or
until the system is free of any air or foreign material resulting from the plumbing work. Close the water tap when
water runs clean.
15.Put the unit back in bypass and refer to start up instructions on page.

12
Special Instructions for Split-Stream and Public Water Supply Installations
For a split-stream installation, a secondary pressure tank must be installed as shown in the split-stream installation diagram (Page
10). On a public water supply installation, a pressure tank must be installed as shown in the public water supply installation
diagram (Page 10). It is recommended in both applications to use a standard air-to-water pressure tank with an air relief valve of a
capacity that would normally be installed if the water system were a standard private well. Also note that in both applications a
normally closed solenoid valve is required. Follow the standard installation instructions above with the following additions and
modifications: See Diagram page 10
1. Install the pressure tank as indicated by the appropriate diagram.
2. Install a normally closed solenoid valve after the water meter and after a line split for untreated water (if there is one).
3. On both types of installation, install the Air injector between the pressure tank (secondary pressure tank on split stream
installations) and normally closed solenoid valve.
4. Install the pressure switch after the Air injector and wire it to the solenoid valve (secondary pressure switch on split-stream
installations). Set high pressure on pressure switch (which controls opening and closing of the solenoid valve) 2 to 3 psi lower
than low pressure on primary pressure switch. EXAMPLE: If primary pressure switch is set at 40-60 psi, set the secondary
pressure switch at 18 to 38 psi.
5. For public water supply installations, contact your local water department or plant operator and ask what the normal low
system pressure is. Set high pressure on pressure switch 2 to 3 psi lower than this figure. NOTE: Failure to set the pressure
switch as described above will not allow proper closing of the solenoid valve during periods of low system pressure.
Start-Up Instructions
1. Plug the valve into an approved power source.
2. When power is supplied to the control, the screen may display “INITIALIZING WAIT PLEASE” while it finds the service position.
3. If the system has been inactive, you may have to hold and press ‘ ’ until you hear a beep to unlock the display screen. Press
“” and hold for 3 seconds to initiate a manual regeneration and advance the valve to the Backwash position. Open the
inlet on the bypass valve slowly and allow water to enter the unit. Allow all air to escape from the unit before turning the
water on fully then allow water to run to drain for 3-4 minutes or until all media fines are washed out of the unit.
5. Press any button to advance to the RINSE position. Check the drain line flow. Allow the water to run for 3-4 minutes or until
the water is clear.
6. Press any button to advance to the SERVICE position. Open the outlet valve to the bypass, then open the nearest treated
water faucet and allow the water to run until clear, close the tap and replace the faucet screen.
7. By cycling the system adjust the air charger bypass to draw air for one third of the cycle time of the pump or pressure system
or for a minimum of 20 seconds whichever is greater.
8. Be sure air vent is installed at the highest point on the inlet to the filter if necessary put in a tee and raise it up so that it is
higher than the head of the filter, before operating system ensure it is in the open position and the cap has been removed.
**NOTE** - during normal operation it is not uncommon for the air vent to sputter some water, if it begins to drip
continuously shut it off and clean with a mild acid solution such as pro res-care or vinegar and reassemble.
Plumbing System Clean-Up
The following procedures are guidelines only but have proven successful in most instances. Under no circumstances should any
procedure outlined below be followed if contrary to the appliance manufacturer's instructions. Should there be any questions
concerning the advisability of performing a procedure, it is strongly recommended the manufacturer's authorized service outlet
be consulted prior to performing the procedure.

13
The plumbing system and water using appliances that have been exposed, even for a short time, to iron-fouled water need to be
cleaned of the precipitated iron that has collected in them or iron bleed (staining) will continue to be a problem.
Depending on the amount of iron in the water and the length of time the water system has been exposed to iron fouling, select
from the following procedures those that apply to the type of system and appliances that need to be cleaned to assure iron-free
water at all points of use.
Softener
It isn't uncommon that the softener was installed in an effort to remove ferrous (clear water) iron from the water supply. Typically
a softener will remove some ferrous iron until the resin bed becomes fouled to the extent that it will lose both hardness removal
capacity and the limited capacity for iron removal. This is the condition to expect the softener to be in when planning a system
clean-up. Prior to closing the main supply valve or turning power off to a private well system and preparatory to installing the
filter system, do the following:
1. Disconnect the brine draw line from the brine cabinet and place the loose end into a five gallon plastic pail filled with a
solution of warm water and 4 oz. of resin mineral cleaner.
2. Advance the control timer to the brine draw position (refer to instructions provided with your softener). Allow all the warm
mineral cleaner solution to be drawn into the mineral bed.
3. Then immediately close the main water supply valve or turn the power off to the pump and proceed with the filter
installation. During the time required to install the filter system, the iron-fouled softener resin will be chemically cleaned.
4. After the filter installation is completed and final adjustments have been made, turn the water back on to the softener,
reconnect the brine draw tube then reposition the timer on the softener to the backwash position. Allow the timer to perform
an automatic regeneration cycle. During backwash of the softener, all iron cleaned from the resin will be washed down the
drain. It is advisable, after chemically cleaning the softener, to regenerate the system twice to fully restore capacity lost due
to iron-fouling.
Water Heater
If the water heater has been exposed to both iron and hardness for a long period of time, replacement of the heater tank may be
the only practical solution to prevent continued staining originating from this source. After completing the installation of the
chemical free iron filter, clean the water heater by following these instructions:
1. Shut off the energy supply to the water heater and close the heater inlet water valve.
2. Drain hot water tank completely. Open inlet water valve, allowing heater tank to be refilled with iron-free water. Continue
flushing until the water runs clear to the drain.
3. If, after approximately 30 minutes of flushing, water does not clear, terminate the flushing operation. Refill hot water heater
with water and pour approximately 1/2 gallon of household bleach into the top of the heater tank. Allow bleach solution to
stand in tank for 20 to 30 minutes. Flush the tank again until water is clear at the drain. Turn energy supply on.
NOTE If water does not clear in approximately 10 minutes, water heater should probably be replaced.

Automatic Bypass The regeneration cycle lasts approximately 1/2 hour, after which filtered water service will be restored.
During regeneration, untreated water is automatically bypassed for use in the household. Hot water
should be used as little as possible during this time to prevent untreated water from filling the water
heater. This is why automatic regeneration is set for sometime during the night and manual regenerations
should be performed when little or no water will be used in the household.
New Sounds You may notice new sounds as your water filter operates. The regeneration cycle lasts approximately 1/2
hour. During this time, you may hear water running intermittently to the drain.
Manual Bypass In the case of emergency, you can isolate your water filter from the water supply using the bypass valve
located at the back of the control. In normal operation the bypass is open with the on/off knobs in line
with the inlet and outlet pipes. To isolate the filter, simply rotate the knobs clockwise (as indicated by the
word BYPASS and arrow) until they lock. You can use your water related fixtures and appliances as the
water supply is bypassing the filter. However, the water you use will not be treated. To resume treated
water service, open bypass valve by rotating the knobs counterclockwise.

15
Maintenance
Maintenance of your new water filter requires very little time or effort but it is essential. Regular maintenance will ensure many
years of efficient and trouble-free operation.
1. Periodically make sure your pump is performing satisfactorily to ensure sufficient water is available for backwashing the filter.
2. Check that the air charger is still drawing air for a minimum of 20 seconds or one third of the pump cycle time whichever is
greater.
3. Periodically test your raw and filtered water to ensure conditions are still the same for your original settings and that the unit
is working they way it is intended to.
4. Periodically check that the drainline and the line between the air charger and the pressure tank are clear and free from any
obstructions.

Trouble Shooting
Issue
Possible Cause
Possible Solution
1. Insufficient air drawn by the air injector
Check air injector adjustment. If unable to adjust
for long enough draw, check pumping rate.
2. Bypass open or leaking
Close bypass and/or repair as necessary.
3. Filter bed overloaded with precipitated iron
due to insufficient backwash
Increase backwash frequency. Upon correction of
problem, manually backwash until backwash water
starts to clear. In more severe iron-fouling cases, bed
may chemical cleaning - contact dealer.
4. Presence of manganese or tannins
Recheck water analysis
5. Flow rate excessive for model
Reread "Facts to Remember While
Planning Your Installation
6. Check valve located between air injector
and pressure tank, disrupting water flow
Relocate check valve
7. Pumping cycle too short
Lengthen pump cycle time
1. Filter bed overloaded with
precipitated iron due to insufficient
backwash flow rate
a. Recheck well pumping rate and repair or replace as
required
b. Check for obstructions or kink in drain line
c. For improper drain line flow controller, see specs.
Upon correction of this problem, if
manually backwashing does not clear bed of iron, filter
bed may need chemical cleaning - contact dealer.
2. Filter bed overloaded with
precipitated iron due to insufficient
backwash
Increase backwash frequency. Upon correction of
problem, manually backwash until backwash water
starts to clear. In more severe iron-fouling cases, bed
may need chemical cleaning - contact dealer.
3. Air injector drawing too much air
causing early precipitation of iron
Reduce Air injector air draw time
4. Air injector installed too far from
pressure tank or pressure tank located too far
from filter tank
Contact dealer for proper location of
Air injector and pressure tank
5. Solenoid valve malfunction or inadequate
supply system pressure/flow rate
Replace solenoid valve, check specs for
proper pressure/flow rates
1. Filter bed overloaded with precipitated iron.
See problem above
2. Control inlet/outlet valve(s) not fully open
Open valves
3. Sand, silt or mud collecting in filter bed
Check well for these conditions
4. Filter bed not properly classified
Manually backwash to reclassify
1. Excess Air injector air draw
Check adjustment for duration of draw in
excess of 1/3 pumping cycle
2. Excess gases in water (carbon
dioxide, hydrogen sulphide, methane)
May require draining of water system or
installation of air relief control - contact
dealer
1. No power supply
Check electrical service, fuse, etc.
2. Defective circuit board
Replace faulty parts
3. Power failure
Reset time of day
1. Iron or scale build up in line feeding unit
Clean pipes
2. Iron build up inside valve or tank
Clean control and add resin cleaner to clean bed.
contact your dealer for instructions
3. Inlet of control plugged due to foreign
material
Remove piston and clean control valve
1. Air in water system
Check well system for proper air eliminator control
2. Incorrect drain line flow control (DLFC)
button
Check for proper flow rate
H. Valve continuously cycles
1. Defective position sensor PCB
Replace faulty parts
1. Valve settings incorrect
Check valve settings
2. Foreign material in control valve
Clean control
3. Internal leak
Replace seals, spacers, and piston assembly
I. Flow to drain continuously
turns red upon standing (stain
producing)
C. Excessive pressure
loss through filter
B. Water red when
drawn from tap
D. Milky or bubbly water
(appears to contain small
bubbles)
E. Unit fails to initiate a
regeneration cycle
F. Low water pressure
G. Filter media in drain line
A. Water clear when drawn;
