SECTION 1: BEFORE INSTALLATION

When properly installed, operated, and maintained, your new softener will provide many years of dependable service. Before starting the installation please read this manual all the way through for an overview, and then follow the installation in proper sequence. Failure to follow instructions will void warranty.

Inspecting And Handling Your Softener:

Inspect the equipment for shipping damage. If damaged, notify the transportation company and request a damage inspection.

Handle the equipment with care. Damage can result if dropped or if the brine tank is set on sharp, uneven projections on the ﬂ oor. When handling, do not turn the water softener unit upside down.

Make Sure Your Water Has Been Thoroughly Tested:

An analysis of your water should be made prior to the selection of your water conditioning equipment. Your dealer will generally perform this service for you,

and may send a sample to the factory for analysis and recommendations. Enter your analysis below for your permanent record.

Analysis of Your Water:

Hardness gpg Tannins (Humic Acid) ppm

Iron (Fe) ppm Hydrogen Sulﬁ de (H2S) ppm

Manganese (Mn) ppm Other ppm

pH ppm

Other ppm

IMPORTANT NOTES

Hydrogen sulﬁ de (H

S) must be tested for at the well site. For accuracy, the sample must be drawn with the

pump RUNNING, and the test be completed within ONE minute after the sample is drawn. Softeners are designed to reduce hardness but can handle reasonable amounts of soluble iron if consideration

is given to content when selecting model and regeneration settings. To treat sulfur (hydrogen sulﬁ de), bacterial iron, precipitated iron or very high levels of soluble iron requires special equipment in addition to a water softener. For best results, a Chem-Free Iron Reduction System is recommended for use on waters containing more than 2 ppm of iron.

1-1

Check Your Pumping Rate and Water Pressure:

Two water system conditions must be checked carefully to avoid unsatisfactory operation or equipment damage:

1) MINIMUM water pressure required at the water softener inlet is 20 psi (1.4 bar). IF WATER PRESSURE IS OVER 80 psi (552 kPa), A PRESSURE REDUCING VALVE MUST BE INSTALLED IN THE WATER SUPPLY LINE AHEAD OF THE WATER SOFTENER.

CAUTION

To reduce the risk associated with property damage due to water leakage:

NOTE: If you have a municipal or a community water supply and daytime water pressure is 85 psi or more, nighttime pressure may exceed 100

psi. Call your local water department or plant operator to obtain pressure readings. If you have a private well, the gauge on the pressure tank will indicate the high and low system pressure. Record your water pressure data below:

Water Pressure:

Low psi High psi

CAUTION

To reduce the risk associated with property damage due to water leakage:

• Do not install system where water lines could be subjected to vacuum conditions without appropriate measures for vacuum prevention.

The installer should take appropriate measures if there is the possibility a vacuum may occur. This would include the installation of an appropriate

device in the supply line to the system, i.e., a vacuum breaker or backﬂ ow prevention device. Vacuum damage voids the factory warranty.

2) The pumping rate of your well must be sufﬁ cient for satisfactory operation and BACKWASHING of the water softener. (See SPECIFICATIONS AND

OPERATING DATA, Section 6)

Locate Water Conditioning Equipment Correctly:

Select the location of your water softener 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 drain.

3) Locate in correct relationship to other water conditioning equipment (Figure 1).

4) Locate the softener in the supply line BEFORE the water heater. Temperatures above 100°F (38°C) will damage the softener and void the factory warranty.

5) DO NOT install the softener in a location where freezing temperatures occur. Freezing may cause permanent damage and will also void the factory warranty.

6) Allow sufﬁ cient space around the installation for easy servicing.

7) Provide a non-switched 110V, 60Hz (220V, 50Hz for speciﬁ ed systems) power source for the control valve.

WARNING

To reduce the risk associated with ingestion of contaminants:

• Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.

CAUTION

To reduce the risk associated with property damage due to water leakage:

• Protect from freezing, relieve pressure and drain system when temperatures are expected to drop below 33°F (0.6°C).

• Do not install on hot water supply lines. The maximum operating water temperature of this ﬁ lter system is 110°F (43.3°C).

• Do not install systems in areas where ambient temperatures may go above 110°F (43.3°C) or below 40°F (4.4°C).

1-2

Facts to Remember While Planning Your Installation:

1) All installation procedures MUST conform to local and state plumbing codes.

2) Remember that the water softener INLET is attached to the pipe that supplies water (i.e. runs to the pump) and the OUTLET is the line that runs toward the water heater.

CAUTION

To reduce the risk associated with property damage due to plugged water lines:

3) Before commencing the installation it is advisable to study the existing piping system and to determine the size, number and type of ﬁ ttings required.

WARNING

To reduce the risk associated with a hazardous voltage:

4) It is also advisable to sweep the ﬂ oor to eliminate objects that could pierce the brine tank.

IMPORTANT NOTE

Sodium Information: Water softeners utilizing sodium chloride for regeneration add sodium to the water softened water. Persons who are on sodium restricted diets should consider the added sodium as part of their overall sodium intake. As a reference as to how much sodium is added to softened water consider the following. For each grain per gallon of water hardness that is exchanged from the water supply, 7.5 milligrams per liter of sodium will be added to the softened water. e.g. 10 grains per gallon (gpg) exchanged will add 75 milligrams of sodium to the softened water.

SECTION 2: INSTALLATION

Step 1) Remove the unit from the shipping box and remove all packaging. Ensure no freight damage has occurred since shipment from our manufacturing

facility. Locate the parts package and install the bypass and adapter ﬁ ttings on the control valve to facilitate the connection to the customer’s water supply.

CAUTION

To reduce the risk associated with property damage due to water leakage:

• On plastic ﬁ ttings, never use pipe sealant or pipe dope. Use PTFE thread tape only, pipe dope properties may deteriorate plastic;

• Take care when using pliers or pipe wrenches to tighten plastic ﬁ ttings, as damage may occur if over tightening occurs.

Step 2) Verify all packaging materials have been removed from the brine tank. On all units, legs rest on bottom of the brine tank.

Step 3) Shut off all water at main supply valve. On a private well system, turn off power to the pump and drain pressure tank. Make certain pressure is relieved

from complete system by opening nearest faucet to drain system.

CAUTION

To reduce the risk associated with property damage due to water leakage:

• SHUT OFF FUEL OR ELECTRIC POWER SUPPLY TO WATER HEATER after water is shut off.

Step 4) Cut main supply line as required to ﬁ t plumbing to INLET and OUTLET of unit.

Step 5) Attach plumbing. DO NOT apply heat to any ﬁ tting connected to BYPASS or CONTROL VALVE as damage may result to internal parts or connecting

adapters. MAKE CERTAIN WATER FLOW ENTERS THROUGH INLET AND DISCHARGES THROUGH OUTLET.

WARNING

To reduce the risk associated with a hazardous voltage:

• If the home electrical system requires use of the cold water system as an electrical safety ground, a jumper must be used to ensure a sufﬁ cient ground connection across the ﬁ lter installation piping — refer installation to qualiﬁ ed personnel.

Step 6) The controls allow for either a 3/4” NPT connection or 5/8” poly tubing for use as a drain line connection.

CAUTION

To reduce the risk associated with property damage due to water leakage:

• On plastic ﬁ ttings, never use pipe sealant or pipe dope. Use PTFE thread tape only, pipe dope properties may deteriorate plastic;

• Take care when using pliers or pipe wrenches to tighten plastic ﬁ ttings, as damage may occur if over tightening occurs.

Step 7) Attach DRAIN LINE to DRAIN LINE FITTING. To prevent back pressure from reducing ﬂ ow

rate below minimum required for backwash, DRAIN LINE MUST be sized according to run length and relative height. Be careful not to bend ﬂ exible drain tubing sharply enough to cause “kinking” (if kinking occurs DRAIN LINE MUST BE REPLACED). Typical examples of proper DRAIN LINE diameters are:

1) 1/2” ID up to 15 ft. when discharge is lower than INLET.

2) 5/8” ID up to 15 ft. when discharge is slightly higher than the INLET.

3) 3/4” ID when drain is 25 ft. away and/or drain is installed overhead.

Some areas prohibit the use of ﬂ exible drain lines. Check with local code ofﬁ cials prior to

installation.

Step 8) Position DRAIN LINE over drain and secure ﬁ rmly. To prevent backsiphoning of sewer

water, provide an air-gap of at least 2” or 2 pipe diameters between end of drain hose and drain (Figure 3). DO NOT raise DRAIN LINE more than 10 ft. above ﬂ oor.

Step 9) Connect one end of the 3/8” black Polyethylene tubing to the brine

ﬁ tting located on the left side of the CONTROL VALVE. Connect the other end to the SAFETY BRINE VALVE ELBOW inside of the brine well in the brine tank. To do so remove the retaining clip from the brine line ﬁ tting on the control valve. The retaining clip is holding

fully opened.

Step 14) Plug the power cord back into the power source. Press the REGEN button and wait for the valve to advance to the

next regeneration position. Repeat the process until the valve is in Service Position (Time will be on the display).

Step 15) Refer to Section 3: Regeneration Instructions, on how to set control valve for proper set up and regeneration

settings.

NOTE: Regeneration settings for the control valve are factory preset. The control valve design permits adjustment

of the salt setting. This adjustment may be necessary when unusual operating conditions exist, such as high concentrations of iron, manganese or hardness and/or high ﬂ ow rates or daily water consumption.
