• 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.

• Do not install in direct sunlight or outdoors.

• Mount system in such a position as to prevent it from being struck by other items used in the area of installation.

• Ensure all tubing and ﬁ ttings are secure and free of leaks.

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

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

• Do not apply heat to any ﬁ tting connected to bypass or control valve as damage may result to internal parts or connecting adapters.

• Install on a ﬂ at/level surface. It is also advisable to sweep the ﬂ oor to eliminate objects that could pierce the brine tank.

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

• Pay particular attention to correct orientation of control valve. Water ﬂ ow should match arrow on control valve. The Inlet and Outlet of other water treatment equipment products will vary depending on the control valve brand used.

• Failure to follow instructions will void warranty.

IMPORTANT: SECTION 1: BEFORE INSTALLATION

Congratulations! We believe your purchase of this water softener will prove to be a very wise choice. When properly installed, operated, and maintained, your new water softener will provide years of dependable service. Before starting the installation, please read this entire manual for an overview, and then follow the installation instructions. Failure to follow the instructions will void the warranty.

Inspecting And Handling Your Water Softener:

Inspect shipping carton and 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 or on its side to help prevent media from entering valve and being discharged downstream.

Make Sure Your Water Has Been Thoroughly Tested:

An analysis of your water should be made prior to the selection of your water softener. You can typically get this service through your place of purchase, which

may require sending 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

IMPORTANT NOTES

The test for Hydrogen sulﬁ de (H2S) must be completed at the well site. For accuracy, the sample must be drawn with the pump RUNNING, and the test be completed within ONE (1) minute after the sample is drawn.

Water softeners are designed to reduce hardness but can handle reasonable amounts of soluble iron if consideration is given to iron content when selecting model and regeneration settings. To treat sulfur (hydrogen sulﬁ de), bacterial iron, precipitated iron or very high levels of soluble iron special equipment in addition to a water softener is required. For best results, please contact your distributor or our customer service department at 866-990-9785.

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 (138 kPa).

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 80 psi or more, nighttime pressure may exceed 125 psi

(689 kPa). 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 is required to take appropriate measures if there is the possibility a vacuum condition 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 Speciﬁ cations And Operat-

ing Data, Section 5)

IMPORTANT NOTE

If sediment is present, the installation of a sediment pre-ﬁ lter is recommended. Even if sediment is not currently present or at a level high enough to be objectionable, a pre-ﬁ lter can help increase the efﬁ ciency of the softener and help reduce the amount of maintenance required.

Installation Site Selection:

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, page 2-1).

4) Locate the water softener in the supply line BEFORE the water heater. Temperatures above 110°F (43°C) will damage the water softener and void the factory warranty.

5) DO NOT install the water 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 40°F (4°C).

• Do not install on hot water supply lines. The maximum operating water temperature of this water softener is 110°F (43°C).

• Do not install in direct sunlight or outdoors.

Facts to Remember While Planning Your Installation:

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

2) If high water demand devices/activities are to be treated by the water softener, a larger model MUST be selected to accommodate the higher ﬂ ow rate plus the backwashing requirements of the water softener. Consult your Dealer/Installer or our Customer Service Department at 1-866-990-9785 for alternative instructions if the pumping rate is insufﬁ cient.

3) Remember that the water softener INLET is attached to the pipe that supplies water (i.e. delivers water from the well pump or after the water meter) 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:

4) Before beginning the installation review 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:

• If the 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 water softener installation piping — refer installation to qualiﬁ ed personnel.

5) Sweep the ﬂ oor to eliminate objects that could pierce the brine tank.

IMPORTANT NOTE

SODIUM INFORMATION: Water softeners using sodium chloride for regeneration add sodium to the water. People who are on sodium restricted diets should consider the added sodium as part of their overall sodium intake.
