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

• Read and follow Use instructions before installation and use of this water treatment system.

• 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°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 professional if you are uncertain how to check for this condition.

• Where a backﬂ ow 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 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.

• 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 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.

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, the Aqua-Pure waters containing more than 2 ppm of iron.

Other ppm

APPM or APIF Series Systems are recommended for use on

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 (138 kPa).

CAUTION

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

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 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

Operating Data, Section 7).

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.

1-2

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 ﬂ ow 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 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 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 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.

Step 1) Remove unit from shipping box, inspect for damage and ensure all parts needed for installation are present. If parts are missing please contact

our customer service department for help @ 1-800-222-7880. Remove the packing from unit and discard according to local, state and federal regulations. 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) NOTE: Extension legs should be installed only whenever a salt dosage on any model water softener is more than 15 lbs. Models utilizing 15”

x 15” x 34” brine tanks require salt grid extension legs when salting the water softener above 15 lbs. of salt or more. Grid legs extension kits are provided for CWS200 units. All other models requiring extension leg kits can be ordered through your Dealer/Installer or our Customer Service Department at 1-800-222-7880.

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 the pressure tank. Make certain pressure is relieved

from the complete system by opening the faucet closest to the 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 ﬂ ow 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 water softener installation piping — refer installation to qualiﬁ ed personnel.

CAUTION

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

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

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

Step 6) The control valve allows 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 ﬁ tting. To prevent back pressure from reducing ﬂ ow rate

below minimum required for backwash, the 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 your local pluming code prior to

installation.

Step 8) Position the drain line over the drain and secure ﬁ rmly. To prevent back-siphoning 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 included 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 a plastic insert sleeve and needs to be inserted into the polyethylene tubing before installing the tubing into the ﬁ tting elbow and hand tighten only. CAUTION: DO NOT use pli-

ers or wrenches to tighten as damage may occur and will void the manufacturer’s warranty.

Step 10) Install the overﬂ ow line to the brine tank overﬂ ow ﬁ tting (Figure

2). The overﬂ ow discharge must be lower than the overﬂ ow ﬁ tting. DO NOT interconnect overﬂ ow line with valve drain line.

Step 11) Make certain the bypass valve inlet and outlet knobs are in

Step 13) Manually set the control to backwash position. Press and hold the

REGEN button for 3 seconds. The valve will advance to the backwash position. Unplug power cord to prevent the unit from advancing automatically.

Step 14) Partially open the inlet knob on bypass valve (Figure 4). This will allow the unit to ﬁ ll slowly from the bottom up, reducing air entrapment. Allow

the unit to ﬁ ll slowly, failure to do so could result in loss of resin to the drain. Once a steady stream of water, with no air sputtering, is ﬂ owing to the drain, the inlet and outlet bypass knobs can be fully opened (refer to Figure 4).

Step 15) 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 the Service Position (Time of Day will be on the display).

Step 16) Refer to Section 3: Control Valve Programming and Regeneration Instructions, on how to set control valve for proper set up and regeneration

settings.

SPECIAL SERVICE INSTRUCTIONS:

Under normal circumstances removal of the valve should not be required. However, if it must be removed, disconnect the plumbing attached to the by-

pass valve ﬁ rst. Then, rotate the valve head assembly to the left or counter-clockwise. Before attempting any disassembly, pressure should be relieved by shutting off water to the system and opening a faucet. Upon reassembly, all o-rings should be lubricated with silicone grease. Reattach valve head assembly by rotating to the right or clockwise until valve head assembly is seated to the tank hand tight. Reconnect the plumbing to the bypass valve.
