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 solu-

tion 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.

-Installation Requirements-

Feed Pot Tank

• A level floor position between the well pump and pressure tank. (See Typical Installation Diagram.)

• DO NOT install in an area of direct sunlight or where freezing temperatures may occur!

Filter Tank

• A level floor position ahead of piping into water heater.

• Unit must be installed at least 10’ ahead of the inlet to a water heater to prevent damage due to back-up of hot water.

• DO NOT install the unit in an area of direct sunlight or where freezing temperatures may occur! (See Typical Installation

Diagram.)

-Filter Location / Other Requirements-

• 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.)

-Installation Procedure-

-Water Supply Connection and Bypass Valve-

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.

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 cap provided 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 cap 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.

Installation

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. It is recommended that a vacuum breaker be

installed on the inlet plumbing.

Bypass - Shown

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!

- Drain Line Connection -

1. The drain line flow control assembly is pre-assembled for your convenience. Should you choose to hard plumb the

drain line, please remove the barb fitting. The flow control housing can be removed by removing the clip and pulling

straight out on housing.

Note: When re-installing the drain line flow control housing, be sure you hear and feel the O-Ring pop into place before

inserting the clip.

2. Install 1/2” I.D. drain line tubing (not included) from hose barb to an open drain. A 4” gap between 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 backwash. 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 feet 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 Amount

G9I / -3 4 1/4” 1.0 cu. ft.

G10I / -3 4 1/2” 1.5 cu. ft.

G12I / -3 5” 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!

Installation Installation

-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.

- Electrical Connection -

1. Connect the power supply to the control valve and plug into a 115 volt / 60 Hz receptacle.

Note: Do not plug into an outlet controlled by a wall switch or pull chain that could inadvertently be turned off.

Installation

-Pressurizing The System -

2. Slowly rotate handle of the bypass valve to the SERVICE position.

3. Open the nearest faucet to evacuate air from plumbing lines.

4. Check for leaks! If water is observed leaking from bypass, o-rings on valve body may not be seated properly. Exercise

bypass valve.

5. After air is evacuated from plumbing lines, turn off faucet.

- Initial Control Valve Operation -

1. Advance control valve to BACKWASH (cycle 1) position and allow water to run to drain for 3 to 4 minutes.

Warning: Close handle on bypass prior to selecting the backwash position. After backwash position has been

established, slightly open valve on bypass to evacuate air from the media tank. Fully open bypass valve when

all air is depleted. This procedure will prevent media form being uplifted into control valve.

2. Advance control valve to RAPID RINSE (cycle 3) position and allow water to run to drain for 3 to 4 minutes.

3. Advance control valve to SERVICE (cycle 0) position.

- Final Checkout -

1. Be certain that the bypass valve is in Service position and main valve is completely on.

2. Check electrical supply to be certain the cord is connected to an uninterrupted 115 volt outlet.

3. Be sure to REGISTER YOUR PRODUCT online at www.csiwater.com

4. Leave this manual with the homeowner.

Important Notice - The plumbing system, piping, pressure tank, hot water tanks, softeners, etc. that have been exposed to

iron bearing water may need to be cleaned of the precipitated iron that has been collected in them or iron bleed thru may

be a problem. We suggest all tanks be drained and flushed thoroughly.

Programming the Control Valve

Normal Operation

1. Home Display

a. 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 Signature 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 Signature 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.
