• Installation and use MUST comply with existing state or local plumbing codes.
• 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 (43.3°C).
• Do not install if water pressure exceeds 125 psi. If your water pressure exceeds 80 psi (552 kPa), you must install a pressure limiting valve. Contact a plumbing
professional if you are uncertain how to check your water pressure.
• Do not install where water hammer conditions may occur. If water hammer conditions exist you must install a water hammer arrester. Contact a plumbing profes-
sional if you are uncertain how to check for this condition.
• Where a backflow prevention device is installed on a water system, a device for controlling pressure due to thermal expansion must be installed.
• Do not use a torch or other high temperature sources near system.
• 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.
• Do not install in direct sunlight or outdoors.
• Install 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 fittings 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 fitting connected to bypass or control valve as damage may result to internal parts or connecting adapters.
• Install on a flat/level surface. It is also advisable to sweep the floor 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 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.
IMPORTANT NOTES
• Failure to follow instructions will void warranty.

SECTION 1: BEFORE INSTALLATION
1-1
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 floor. 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.
IMPORTANT NOTES
IMPORTANT NOTES
Water softeners are designed to reduce hardness and reasonable amounts of soluble iron if consideration is given to iron content when selecting
model and regeneration settings. To treat sulfur (hydrogen sulfide), bacterial iron, precipitated iron or very high levels of soluble iron special equip-
ment in addition to a water softener is required. For best results, the Aqua-Pure®APPM or APIF Series Systems are 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 (138 kPa).
CAUTION
To reduce the risk associated with property damage due to water leakage:
• Do not install if water pressure exceeds 125 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: 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 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).
IMPORTANT NOTE
If sediment is present, the installation of a sediment pre-filter is recommended. Even if sediment is not currently present or at a level high enough to be
objectionable, a pre-filter can help increase the efficiency 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 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 40°F (4°C).
• Do not install on hot water supply lines. The maximum operating water temperature of this water softener is 110°F (43.3°C).
• Do not install in direct sunlight or outdoors.

Facts to Remember While Planning The Installation:
1) All installation procedures MUST conform to local and state plumbing codes.
2) If lawn sprinklers, a swimming pool, or geothermal heating/cooling or water for other devices/activities are to be treated by the water softener, a
larger model MUST be selected to accommodate the higher flow rate plus the backwashing requirements of the water softener. Consult your Dealer/
Installer or our Customer Service Department at 1-800-222-7880 for alternative instructions if the pumping rate is insufficient.
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:
• 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.
4) Before beginning the installation review the existing piping system and to determine the size, number and type of fittings required.
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 water softener installation piping — refer installation to qualified personnel.
5) Sweep the floor 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.
