Description of the water softener system
This nitrate reduction system includes a brine (salt) tank and a resin (media) tank with a backwashing control valve. Incoming water flows into the control valve and is directed down through the anion exchange softening resin. This resin exchanges the nitrates and other anions for chloride ions. The treated water then returns to the control valve where it is directed into the service lines.
Periodically the control valve will go through a regeneration cycle. The frequency of this regeneration process will depend on the size of water softener, incoming water quality and amount of water used. This cycle is factory preset to begin at 2:00 A.M. At this time the control valve will draw the brine solution out of the salt tank and flush both the accumulated hardness and excess salt to the drain. The control valve will then put fresh water back into the salt tank to make brine for the next regeneration cycle.
Water Quality
The water should be tested to determine the concentration, or levels of the items listed below:
Hardness - Hardness in drinking water is defined as those minerals that dissolve in water having a positive electrical charge (cations). The primary components of hardness are calcium (Ca++) and magnesium (Mg++) ions. But dissolved iron (Fe++) and manganese (Mn++) also contribute to total
“adjusted” hardness. Hardness produces scale, soap scum and white mineral deposits which shorten the life of water using appliances, plumbing and fixtures. Water that has less than 1 grain of hardness is considered to be “soft” water. Please note the FSN does not reduce hardness and, in fact, must be supplied with soft water.
pH - A measurement of the acidity of the water. pH is reported on a scale from 0 to 14. Neutral water has a pH of 7.0, lower values indicate acidic water. If your pH is below 6.8 you may consider installing an acid neutralizer before the water softener to elevate the pH.
Iron - A naturally occurring metallic element. Iron levels in excess of 0.3 milligrams/liter (mg/l) combine with oxygen causing orange or red (rust) stains on plumbing fixtures. Iron exists in some water sources in clear water (ferrous) state, red water (ferric) state or bacterial form. Iron levels that exceed 2.0 mg/l require special ion exchange resin for reduction, or if bacterial or ferric (red water) iron is present or iron level exceeds 4.0 mg/l, an iron filter should be installed. Water supplied to the FSN must not exceed 0.05 ppm iron content.
Manganese - A naturally occurring metallic element. Manganese levels as low as 0.05 milligrams/liter (mg/l) can combine with oxygen to cause dark brown or black staining on fixtures. Additionally, manganese can cause an odor in the water similar to a “rotten egg” smell. The FSN does not reduce manganese.
Tannin - A naturally occurring humic acid. Tannin is caused by water passing through decaying vegetation.
Coffee and Tea are prime examples of tannin in water. Tannin levels as low as 0.5 milligrams per liter can cause a yellow discoloration in water. Consult your dealer for a system designed to remove both tannin and hardness. The FSN does not reduce tannin.
Hydrogen Sulfide - A naturally occurring gas. Hydrogen sulfide, more commonly referred to as sulfur gas, causes a distinct odor similar to “rotten eggs.” Due to its gaseous nature, hydrogen sulfide must be tested at the well site within 1 minute of drawing the sample. If sulfur is present additional equipment will be required. The
OXY3 iron filter can typically treat up to 2 milligrams per liter of sulfur gas. The FSN does not reduce hydrogen sulfide.

Pre-installation Instructions (cont.)
Location Considerations
Treated
The proper location to install the water softener system will ensure optimum performance and satisfactory water quality. The following factors should be considered in selecting the location of the equipment.
Cold Water
1. The water softener should be installed after the pressure tank on a private well system or after the water meter on municipal water. Operating pressure of the softener must be limited to within 30 –
100 psi range.
2. The water softener 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).
3. All water conditioning equipment should be installed prior to the water heater. Water temperatures exceeding 100°F can damage the internal components of the control valve and filter tank. Install with at least 10’ of pipe before the water heater to prevent thermal damage to the equipment. 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. The water softener should not be subject to freezing temperatures.
5. Ensure that any cartridge or in-line type filter installed prior to the water softener does not restrict the water flow and pressure available for backwash and interfere with normal operation.
6. 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 water softener.

Place unit at desired installation position. DO NOT plug into electrical outlet at this time
(see STEP 10 on page 6). DO NOT put salt into brine tank at this time (see STEP 18 on
page 6).
Shut off water at main supply. Relieve pressure by opening nearest faucet. On private well systems, turn off power to pump and drain pressure tank. SHUT OFF POWER OR FUEL
SUPPLY TO WATER HEATER.
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.
Use the provided polyethylene tubing (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 softener (refer to specifications and flow rate on page 10). 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.

Installation Instructions
Plug the softener into an unswitched electrical outlet and slowly rotate the Manual
Regeneration Knob (see Fig. 5, page 7) clockwise just until one click is heard. This is the
“BACKWASH” position.
Unplug the softener from the electrical outlet to keep it in the backwash position.
Refer to Figure 4 (page 5) for appropriate bypass valve operation. Rotate bypass lever of stainless steel bypass ¼ of the way to “Service” allowing unit to fill slowly. You should hear water trickling into the mineral tank. Filling the mineral tank in this position will force any trapped air to the drain. When all air has been purged from the system and only water is
running to the drain, slowly open the bypass valve fully to the service position.
Add enough water to the brine tank to a level approximately 1” above the salt grid.
Plug the softener back into the electrical outlet.
Slowly rotate the Manual Regeneration knob clockwise until just one click is heard. This is the Brine Draw position. Verify that the water level in the brine tank is dropping. Allow water level to drop below the salt grid before continuing. If the water level does not drop, refer to page 15 for Troubleshooting. Otherwise, advance the control valve to the service position (see Fig. 5, page 7) by continuing to rotate the knob clockwise until the Service
Position Indicator is in line with the Time of Day Arrow.
Check for leaks and correct as necessary.
Turn on power or fuel supply back on to water heater.
Set the current time of day on the timer (note AM and PM) (refer to Fig. 5).
Set the regeneration frequency (refer to Fig. 5).
Fill the brine tank with salt.

FSN Series Time Clock Setting Instructions
Timer Operation
FIGURE 5: Front of Time Clock Timer Assembly
How to set Time of Day:
1. Press and hold the red button to disengage the 24 hour gear.
2. Turn the large 24 hour gear until the actual time of day is at the time of day arrow.
3. Release the red button to again engage the 24 hour gear.
How to set the Days of Regeneration:
It is recommended that you contact First Sales technical services to have your regeneration schedule calculated based on test results you received from a certified laboratory. Otherwise, use Table 1 or Table 2 from page 8 to get an approximation of the regeneration schedule required:
1. Refer to the appropriate table for your water softener model number (page 8) to determine how many TIMES in a 12 day cycle the FSN should regenerate. If the nitrate level falls between two numbers in the table, use the next highest number.
Example: FSN10
4 people in family
Nitrates 35 ppm
Result: Set softener to regenerate 2 TIMES in 12-day cycle (once every 6 days)
2. Rotate the skipper wheel until the number 1 is at the red pointer. 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 Regeneration Cycle:
1. Grab the manual regeneration knob and turn clockwise SLIGHTLY. The drive gear will engage the backwash knob which will make a complete revolution and return to the “Service” position after the regeneration cycle.
