Installation
Greensand Plus Iron Filter is capable of removing dissolved iron, manganese and hydrogen sulfide from water through
oxidation and filtration. The maximum practical limit of iron (Fe) and / manganese (Mn) in raw water is 10 ppm. The
maximum practical limit of hydrogen sulfide (h2S) is 3ppm. Raw water pH should be 6.8 to 8.8.
Manganese treated greensand works as an oxidizing filter to remove the dissolved minerals above. The manganese
oxides convert the soluble ferrous minerals in the water into ferric (or floating particles) minerals. As the ferric hydroxide
forms, it is filtered from the water by the granular material in the tank.
When the oxidizing capacity of the filter media becomes exhausted, regeneration is necessary. First the filter valve
bypasses the raw water to the system to provide uninterrupted service. The valve then reverses the flow of the water
through the filter bed to produce a backwash to the drain. Because of the density of the media bed, it is very important to
size the filter to the pump volume thus insuring adequate supply for backflushing.
The valve then brings in dissolved potassium permanganate from the small feeder tank and rinses it slowly through the
greensand media. The introduction of this oxidizing agent replaces the oxygen lost during normal service and restores the
managanese dioxide coating on the filter material renewing it for further service. A fast rinse then follows to settle the media and insure that the chemical is rinsed away. The valve then refills the potassium permanganate tank to make solution
for the next time. Service flow is downward through the filter media and up through the distributor tube in the center of the
tank.
It is recommended that the greensand media be vigorously regenerated when new and that it be regenerated before it is
exhaused while it is in service.

SIGNATURE 2 SERIES
Installation
• Locate the unit near an unswitched, 120 volt / 60 Hz grounded electrical outlet.
• Check for distance and proper drain installation (e.g. floor drain, washing machine standpipe).
• Determine type and size of piping required for softener connection (e.g. copper, galvanized, PVC plastic).
Note: Where the drain line is elevated above the control valve or exceeds 20 feet in length to reach the drain, use 3/4”
I.D. drain line tubing of 1/2” I.D. Drain line tubing is not included.
Caution: If sweat soldering copper pipe, (remember to always use lead free solder and flux) cover yoke and bypass valve
with wet rags to prevent heat damage to connections and control valve! If using PVC or plastic pipe, primers and solvent cements specifically recommended for use with potable water are required.
Note: All plumbing lines not requiring soft water should be connected upstream of the filter. (See Typical Installation
Diagrams.)
To allow for filter servicing, swimming pool filling or lawn sprinkling, a manual bypass valve has been installed at the
factory. The bypass allows raw water to be manually routed around the filter.
-Filter Location / Other Requirements-
-Installation Procedure-
-Water Supply Connection and Bypass Valve-
1. Position filter at desired location for installation. If a water softener is to be installed, the filter should be positioned first
and then the softener. (See Installation Diagrams.)
2. The filter material is shipped separately from the mineral tank. The tank must be loaded with material after tank has
been placed at the desired location.
a. Remove the control valve by unscrewing from the tank.
b. Remove and inspect distributor tube and bottom basket.
c. Replace distributor tube and use a cork or tape to place over top of distributor tube to prevent mineral from entering tube while filling.
d. Place mineral funnel in hole on top of tank.
e. Pour several gallons of water in the tank.
Caution: Not following this procedure can cause damage to distributor tube or basket when loading material!
f. First pour in the filter material.
Note: The required quantity of gravel is in the tank already.
g. After filling the tank with material, use a garden hose or several buckets to fill the tank with water.
Note: This will permit the filtering material to become soaked while preparing the installation and will prevent the control
valve from being plugged with floating material on initial backwash.
h. Remove funnel and clean filter material from tank threads.
i. Remove cork or tape from distributor tube.
j. Replace control valve on mineral tank.
Caution: Be extremely careful to position distributor tube into control valve distributor tube pilot hole.
3. Turn off main water supply and open nearest faucet to relieve pressure.
4. Cut main line and install elbows and extensions. Inlet and outlet connections on the control valve are 3/4” FNPT.
Note: An optional 1” FNPT bypass is available.
Caution: Raised arrows located on the sides of control valve body and bypass valve indicate proper direction of water
flow. Install inlet and outlet piping in direction of arrows.
5. Rotate handle on bypass valve to the bypass position (position of handle is across inlet/outlet piping).
6. Turn the main supply line on to restore water service to the home.
7. Open nearest faucet to evacuate air and repressurize plumbing lines.
8. Check for leaks!

Installation
-Drain Line Connection-
1. Pull out clip and remove drain line assembly located on the left side of control valve. Remove drain line hose barb and
wrap threads with Teflon tape. Reinstall drain line hose barb. Caution: Hand tighten only!! Replace drain line assembly
and reinstall clip.
2. Install 1/2” I.D. line tubing (not included) from hose barb to an open drain. A 4” gap between the end of the drain line
and the open drain is required to prevent waste water backflow. Keep the drain line as short as possible. An overhead
drain line can be used if necessary but should discharge below the control valve. A syphon trap (taped loop)
at the outlet of the drain line is advisable to keep the drain line full and assure correct flow during regeneration. Elbows
or other fittings must be kept at a bare minimum.
Note: Where the drain line is elevated above the control valve or exceeds 20’ in length, 3/4” I.D. drain line tubing should
be used.
-Potassium Permanganate Feed Rate-
The amount of potassium permanganate fed during regeneration is automatically controlled by the float assembly located
inside the feed tank. This is an adjustable float, which must be set at a minimum of 4 1/4”, but not higher than 5 1/2”. This
distance is measured between the bottom of chemical feed valve and the bottom of the float with the valve closed (float
UP position). The float settings for each model are as follows:
Model # Float Setting Media AmountIF-10-S2 4 1/4” 1.0 cu. ft.
IF-15S2 4 1/2” 1.5 cu. ft.
IF-20-S2 IF-25-S2 5 1/2” 2.0 cu. ft.
1. To measure and set the float, remove the chemical well cap and float assembly.
2. Remove rubber band from float valve.
3. Measure distance from bottom of chemical feed valve to the bottom of float with the float in the UP position. To move
float, slide rubber grommets up and down float shaft. Make certain both upper and lower grommets are
tightly against float body. Replace float assembly and chemical well cap.
WARNING: After adjustment, ensure that the float maintains proper up and down travel, otherwise, overfilling of the feed
tank could occur!
-Chemical Feed Line and Overflow Connections-
1. Position Potassium Permanganate Tank (KMNO4) on a smooth, level surface near the filter media tank. If necessary,
the KMNO4 tank can be placed at a higher level than the resin tank, but never at a lower level.
2. Install one end of 3/8” O.D. by 1/4” I.D. chemical line tubing (included with unit) to compression fitting located on right
side of control valve, behind backplate.
3. Remove KMNO4 tank cover.
4. Insert opposite end of chemical line through outer hole in KMNO4 tank.
5. Connect chemical line to compression fitting on float valve located on top of chemical well.
6. Install 1/2” I.D. drain line tubing (not included) to the overflow fitting on KMNO4 tank located just below the chemical
line.
7. Run the opposite end of KMNO4 tank drain line to a suitable drain.
Note: The KMNO4 tank drain is gravity flow and must discharge below the overflow fitting.
Caution: Do not tee to the main drain line from control valve.
NOTICE: The KMNO4 overflow is provided as a back-up in the event the float shut-off should fail, allowing the KMNO4
tank to overfill. This drain connection would then carry the excess chemical to the drain and prevent flooding of the floor,
which could be hazardous to health or damage furniture or carpets. Therefore, no liability will or can be assumed by the
manufacturer of the filter should this occur.

Control Start-Up Procedures
Normal Operation
1. Home Displaya. Alternates between the display of Time of Day and Number of Days until the Next
Backwash. (Metered Softeners will alternate between time of days and gallons
remaining until next regeneration)
- Days Remaining until the Next Backwash will count down from the entered
value until it reaches 1 day remaining.
- A Backwash Cycle will then be initiated at the next designated regeneration time.
2. Battery Back-Up (Uses a standard 9-volt alkaline battery.)
Features of Battery Back-Up:
• During power failures, the battery will maintain the time of day as long as the
battery has power. The display is turned off to conserve battery power during
this time. To confirm that the battery is working, press either button and the
display will turn on for five (5) seconds.
• If power failure occurs while system is regenerating, the Isobar 2 will motor to a shut off position to prevent constant flow to drain. Depending
upon system pressure and other factors, it is possible to observe a reduced flow to
drain during this step. After power is restored, the Isobar 2 will return and finish the cycle where it left off prior to the power interruption.
• When used without battery back-up, during a power failure, the unit stops at its
current point in the regeneration position and then restarts at that point when the
power is restored. The time will be offset by the increment of time the unit was
without power, so it is necessary to reset the time of day on the unit. No other
system will be affected.

Error Codes
There are five (5) error codes which could indicate a possible problem with the control valve:
Error 2 - Valve is searching for homing slot.
Allow valve to run until homing slot is found or new error code appears.
Error 3 - No encoder slots are being seen.
Check encoder connection. If encoder is connected. Check valve body for debris
and replace seals. Inspect piston and replace if worn.
Error 4 - Unable to find homing slot.
Check encoder wheel for debris.
Error 5 - Motor overload.
Check valve body for debris. Replace seals. Inspect piston and replace if worn.
Check motor operation and replace motor if unresponsive.
Error 6 - No power to motor. Check motor connections, replace motor if unresponsive.
