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 floor. 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:

IMPORTANT NOTES  
Hydrogen sulfide (H2S) 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 sulfide), bacte-  
rial 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.

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 REDUC-  
ING 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:  
Do not install if water pressure exceeds 100 psi. If your water pressure exceeds 80 psi (552 kPa), you must install a pressure limiting valve. Contact a plumb-  
ing professional if you are uncertain how to check your water pressure.  
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:

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 backflow prevention device. Vacuum damage voids the factory warranty.  
2) The pumping rate of your well must be sufficient 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 sufficient space around the installation for easy servicing.  
7) Provide a non-switched 110V, 60Hz (220V, 50Hz for specified 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 filter 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).

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:  
• Pay particular attention to correct orientation of control valve. Water flow 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.  
3) Before commencing the installation it is advisable to study the existing piping system and to determine the size, number and type of fittings re-  
quired.  
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 sufficient ground connection across  
the filter installation piping — refer installation to qualified personnel.  
4) It is also advisable to sweep the floor 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 re-  
stricted 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  
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 fittings on the control valve to facilitate the connection to the customer’s  
water supply.  
Step 1)  
CAUTION  
To reduce the risk associated with property damage due to water leakage:  
• On plastic fittings, 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 fittings, as damage may occur if over tightening occurs.  
Step 2)  
Step 3)  
Verify all packaging materials have been removed from the brine tank. On all units, legs rest on bottom of the brine tank.  
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)  
Step 5)  
Cut main supply line as required to fit plumbing to INLET and OUTLET of unit.  
Attach plumbing. DO NOT apply heat to any fitting 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 sufficient  
ground connection across the filter installation piping — refer installation to qualified 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 fittings, 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 fittings, as damage may occur if over tightening occurs.
