How A Water Softener Works
Water hardness is derived from Calcium and Magnesium minerals that have been dissolved into the water under the earth’s surface. These minerals are found in limestone deposits and are the source of hard water. The amount of hardness in a given water supply is dependent upon the quantity of Calcium and Magnesium present and the length of time water has been in contact with them. This can vary dramatically from well-to-well and, for this reason, water analysis is imperative in order to determine the proper treatment method. The degree of hardness increases as the concentration of Calcium and Magnesium “ions” increase and is measured in Grains Per Gallon (gpg). Diamond H2O’s state certified lab is capable of performing all of these tests in house as well as lead, copper, arsenic, nitrate, nitrite, coliform bacteria, and many other essential tests to help determine the best possible treatment of your water. Contact TGA Laboratories for details on testing (www.tgalabs.com).
The problem of hard water in the home / business comes to light in many facets of daily use. Water spots and scum left behind on bathtubs, fixtures and showers; wear and tear on appliances; calcium build-up in hot water heaters and piping; and, greater amounts of soap and detergents being used are just a few examples.
The modern water softener is designed to reduce hardness ions and their unpleasant side effects. Special resin beads in the softener are used to change hard water into soft water. The surfaces of these beads are covered with sodium ions. As hard water enters the softener and comes into contact with the resin, an exchange of ions takes place. As dissolved Calcium and Magnesium ions cling to the resin surface, sodium ions take their place, thus softening the water. This process is called Ion Exchange. Over time, the sodium ions used for the exchange process become depleted and must be replenished.
The water softener provides a Regeneration process (see page 4 for diagrams) whereby brine solution enters the softener, driving-off the collected hardness ions and replenishes the surface of the resin beads with more sodium ions. This process is automatically initiated by the control valve on the softener. The regeneration process has five basic cycles as follows:

1. Backwash – The control valve directs the water flow in a reverse direction through the softener, separating the resin beads and flushing any accumulated particles to a waste drain.
2. Brine & Rinse – In the first part of this cycle, the control valve directs brine solution downward through the softener, driving-off collected hardness ions and replenishing the resin beads with sodium ions. The second part of the cycle rinses hardness ions and excess brine from the softener to the waste drain.
3. Rapid Rinse – The control valve directs the water flow downward, settling and recompacting the resin bed.
4. Brine Refill – The control valve directs fresh water into the salt compartment to create new brine solution for the next scheduled regeneration.
5. Service – This is the normal “operating” cycle where hard water enters the softener, comes into contact with the resin beads and exchanges hardness ions for sodium ions – the water then becomes “soft” and ready for use.

Installation Requirements

• 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 Installation Diagrams for proper placement and plumbing connections.)

Major System Components-

1. Brine Tank – This tank holds the salt that is added to the softener. This salt is dissolved with water to form a brine solution used in the softener regeneration process.
2. Softener – This tank contains the ion exchange resin media. Water flows through the softener under pressure to come into contact with the resin for water softening.
3. Control Valve – The valve directs water through the softener for water softening and controls the flow of water / brine for the regeneration process.

Softener Location / Other Requirements-

• If household plumbing is galvanized and you intend to make the installation with copper (or vice versa), obtain di-electric unions to prevent dissimilar metal corrosion.
• 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 instead of 1/2″ I.D. Drain line tubing is not included.
• All plumbing lines not requiring “soft” water should be connected “upstream” of the softener.
• The brine tank drain line is gravity flow and must discharge below the overflow fitting.
• The brine overflow is provided as a back-up in the event the safety float shut-off should fail, allowing the brine tank to overfill. This drain connection would then carry the excess water to the drain and prevent flooding of the floor. Therefore, no liability will or can be assumed by the manufacturer of the softener should this occur.

Caution

• If sweat soldering copper pipe (remember to always use lead free solder and flux), cover 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.
• Do not “TEE” to the main drain line from control valve.

Obtain the required tools listed below:

• Utility Knife
• Pliers
• Phillips Screwdriver
• Hammer
• Level
• Softener filling funnel

Place the tanks near a water source.

• Select a position near a floor drain that has adequate carrying capacity to handle the backwash flow rate.
• Place the softener(s) and brine tank on a level, firm foundation, like concrete.
• Determine the “front” of each tank received. For each tank:
  • Make sure that the distributer riser is flush with the top of the resin tank (Figure 10 on page 6).
  • Before placing any water, gravel, or resin in the resin tank, screw in the control valve to the point where it is secure. The valve does not need to be forced on, but should be snug.
  • Mark the “front” of each resin tank (shown in Figure 8) with either a marker or tape. The front of the resin tank is determined by the location of the face of the control valve once it has been secured to the face of the control valve. Make sure that the system is positioned in a way that the plumbing can be installed.
• Before Filling the Tanks:
  • Remove the valve(s)
  • Ensure that the front(s) of the tank(s) is/are positioned correctly. Once filled, the resin tanks will be very difficult to move.
  • Cover the exposed end of the distributor riser(s) to make sure no resin gets inside. Covering up the riser(s) with duct tape is one option, shown in Figure 8.
  • Obtain a funnel to assist placing the resin in the resin tanks. (A funnel designed specifically for our resin tanks can be ordered from Diamond H2O Conditioning.)

Setting up the tank

• Fill the tank up to 30% full of water.

• Check the system specifications on page 2 to determine the correct amount of gravel and resin needed for your system.

• Position the distributor tube so it is in the center of the tank, shown in Figure 10.

• SLOWLY, pour the correct amount of support gravel into the tank without getting any gravel into the distributer tube.

• Visually confirm that the gravel is level and covering the distributor basket and radials, if it is not, contact Diamond H2O Conditioning.

• SLOWLY, pour the correct amount of resin into the tank. Try to keep the media level by carefully rocking the tank back and forth.

• Fill the rest of the tank with water to prevent air from getting in the tanks and potentially losing media.

• Verify that there is a large O-ring on the control valve(s) adapter base. (Figure 12)

• Place the control valve on the tank, making sure that the distributor tube fits into the bottom of the control valve.

• Tighten the control valve onto the tank to the point that it is snug. Double check that the valve is in a correct position to be able to install the plumbing.

Connect the brine tank

• Remove the ties on the brine line hose (included in the brine tank).
• Remove the well cap and connect one end of the brine line hose to the brine line connection (Shown in Figure 14) of the brine tank. Tighten the brine line hose to the brine line connection by turning the cap of the brine line connection clockwise by hand. Make sure that no air can get into the line, or the softener will not regenerate properly.

• Attach the brine line to the valve’s brine inlet shown in figure 15.
• Safely dispose of any leftover tubing.
• Fill the brine tank with salt.

Connect the Valves to the Water Source

• Pipe or tube a line from the Control Valve Drain (Figure 15) to the drain.
  DO NOT

  • install a valve in this line
  • use a pipe smaller than the unit’s inlet or outlet
  • make a direct connection to the drain
  • Provide an air gap at least four times the diameter of the drain pipe to conform to sanitation codes and be able to observe the drain flow.
  • use an excessive amount of elbows in the plumbing

• Turn off the main water supply and open nearest faucet to relieve pressure. Connect the facility plumbing to the control valve inlet and outlet following all local codes.
  Note: Make sure all piping is free of thread chips and other foreign matter.

• Turn the bypass valve to the “bypass” position (shown below).

• Turn the main supply on to restore water service to the home.
• Open the nearest faucet to evacuate air and re pressurize plumbing lines.
• Check for leaks.

Connect the power supply

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

Start up the system for the first time

• Add about three gallons of water to the brine tank.
• Double check that the tanks are filled with water.
  • Manually put the control valve into regeneration (Hold the SET/CHANGE button or press the “regen now” button in the Diamond Linq app)
  • While the system is in backwash (cycle 1), slowly change the adjust the bypass valve to the “service” position.
  • A mixture of air and water will flow from the drain line.
  • Once the tank is filled, only water will be coming out of the drain line. Put the system back into bypass operation. Run each step of the regen cycle (Figure 7) for a few minutes each. You can advance to the next step by holding the SET/CHANGE button.
• Program the Valve. Most of the settings were programed to Diamond H2O’s default values.
  The rest of the site-specific settings should be set by an installer after the water quality (pH, TDS, total hardness, and iron) have been determined. These settings can be changed with the valve’s two buttons (page 11) or by using the Diamond LINQ app (page 14).

Control Valve Error Code Diagnosis

Under normal operating conditions, when your control valve is in the “in service” position, the display should alternate between the current time of day and the number of days remaining (for filters and time clock softeners) or gallons remaining (for metered softeners) until the next regeneration. This is the “home display.” If the valve is currently going through a regeneration cycle, the display will show the cycle step on the left side of the display and the number of minutes remaining in that step on the right side of the display. If any other information is being displayed, then the valve is informing you of an issue. There are five error codes which could indicate an issue with the control valve. When an error is being displayed, the valve will be in a stopped position, and the buttons will not respond to being pressed. Even if the cause of the error code is corrected, the error code will not clear until the power supply has been disconnected and reconnected (this will be referred to as “cycling” the power). All error codes are displayed as the letters “Err” followed by a flashing number 2-6:

Error 2 – Valve is searching for homing slot. Allow valve to continue running. If the homing slot is found, the valve will return to the home display, otherwise, another error code will appear.

Error 3 – No encoder slots are being seen. This occurs when the motor is running, but the encoder is not seeing any of the slots in the encoder wheel. This can happen if the encoder has been disconnected, but most commonly occurs when debris in the valve body has stopped the piston, causing the encoder wheel to be unable to turn.

1. Check encoder connection. If the encoder is plugged in and snapped into place, skip to step #2 below. If encoder is disconnected, reconnect it and cycle power to clear the error.
2. Disconnect powerhead from valve body, cycle power to clear the error code. Manually cycle the powerhead through the regeneration cycle steps to verify that the motor can cycle properly while the powerhead is disconnected from the valve body. If the error 3 does not reappear, skip to step #3 below. If the error 3 does reappear, order a board & motor kit to replace the circuit board & motor.
3. Remove piston and seals from the valve body and inspect valve body for debris. Replace the seal & spacer kit. Inspect piston and replace piston if Teflon coating is worn

Error 4 – Unable to find homing slot.

1. Check encoder wheel for debris.
2. Cycle power. Valve should either find home or go to a different error code. If error 4 returns, replace powerhead assembly.

Error 5 – Motor overload.
This occurs when the motor current is too high. This could be caused by an issue with the motor itself, but is typically caused by friction in the valve body

1. Disconnect powerhead from valve body and cycle power to clear the error code.
2. If the error 5 returns, replace the motor. Otherwise, manually cycle the powerhead through the regeneration cycle steps to verify that the motor can cycle properly while the powerhead is disconnected from the valve body. Either way, proceed to the next step.
3. Remove piston and seals from the valve body and inspect valve body for debris. Replace the seal & spacer kit.
   Inspect piston and replace piston if Teflon coating is worn.

Error 6 – No motor current.
This typically occurs if the motor cable has come unplugged from the circuit board. Check that the motor cable is plugged into the circuit board and attached to the motor. If this is not the issue, the motor or circuit board may need to be replaced.

No Display
If your display is blank, there is no power going to the circuit board due to one of the following factors:

• The electrical outlet is not powered or is switched off
• The power cable has come unplugged from the circuit board
• The power supply has come unplugged from your electrical outlet
• The power supply has come unplugged from the control valve
• The power supply is not working
