SECTION 1: BEFORE INSTALLATION

Congratulations! We believe your purchase of this water softener will prove to be a very wise choice. When properly installed, your new softener will provide many years of virtually trouble-free service. Before starting the installation we suggest you read this manual all the way through for an overview, and then follow the installation in proper sequence.

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 softener 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 a permanent record.

IMPORTANT NOTES

Softeners are designed to remove 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 Filter is recommended for use on waters containing more than 2 ppm of iron.

Check Your Water Pressure:

CAUTION

IMPORTANT NOTE

CAUTION

Water pressure must be checked carefully to avoid unsatisfactory operation or equipment damage:

• MINIMUM water pressure required at the water softener inlet is 20 psi (137.9 kPa). IF WATER PRESSURE IS OVER 100 PSI (689 kPa), A PRESSURE REDUCING VALVE MUST BE INSTALLED IN THE WATER SUPPLY LINE AHEAD OF THE WATER SOFTENER.

CAUTION

Do not install if water pressure exceeds 100 psi (689 kPa). If the system water pressure exceeds 100 psi, the installation must use a

pressure limiting valve. Contact a licensed plumbing professional if you are uncertain how to check your water pressure.

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

IMPORTANT NOTE

If you have a municipal or a community water supply and daytime water pressure is 85 psi (586 kPa) or more, nighttime pressure may exceed 100 psi (689 kPa). Call your local water department or plant operator to obtain pressure readings. Record your water pressure data below:

Water Pressure:

Low psi High psi

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 warranty.

CAUTION

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

• The system must be installed on cold water lines only, maximum temperature 100°F (38°C).

• Do not install this system in direct sunlight or outdoors without protection from precipitation.

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

Facts to Remember While Planning Your Installation:

WARNING

CAUTION

IMPORTANT NOTE

WARNING

To reduce the risk associated with 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 softener installation piping — refer installation to qualiﬁ ed personnel.

CAUTION

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

• Installation must comply with existing state or local plumbing codes.

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

• Do not use torches or other heat sources near plastic plumbing, as damage may occur.

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

• On plastic ﬁ ttings, use thread sealing tape only. Never use pipe sealant or pipe dope on plastic ﬁ ttings, as damage may occur.

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

If lawn sprinkling, a swimming pool, geothermal heating/cooling or water for other devices/activities are to be treated by the softener, a larger model softener MUST be selected to accommodate the higher demands of these items. Consult your dealer for alternative instructions if the pumping rate is insufﬁ cient.

Remember that the valve INLET is attached to the pipe that supplies water (i.e. runs to the pump) and OUTLET is the line that runs toward the water heater or other water treatment equipment device.

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. Typical system schematics shown in Figure 1 will be of assistance.

IMPORTANT NOTE

Sodium Information: Water softeners utilizing sodium chloride for regeneration add sodium to the 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.

WARNING

CAUTION

WARNING

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.

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.

Step 2

Verify all packaging materials have been removed.

Step 3

Shut off all water at main supply valve. Make certain pressure is relieved from the complete system by opening nearest faucet to drain system.

CAUTION

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

• When water supply is shut off, shut off fuel or electric power to water heater.

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.

CAUTION

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

• Do not use torches or other heat sources near plastic plumbing, as damage may occur.

• On plastic ﬁ ttings, use thread sealing tape only. Never use pipe sealant or pipe dope on plastic ﬁ ttings, as damage may occur.

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

WARNING

To reduce the risk associated with hazardous voltage:

• Do not use the Water Softener if the wall-mounted power supply is damaged — contact qualiﬁ ed service personnel for repair.

Step 6

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:

a) 1/2” ID lengths up to 15 feet and heighs lower or slightly higher than the control

valve.

b) 5/8” ID length up to 25 feet in length and up to 4 feet above the control valve.

c) For distances higher or longer than previously stated, relocated the softener closer

to the desired discharge point or consult factory for advice. Avoid overhead drain lines as it may prevent desirable performance.

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 a plastic insert sleeve and needs to be inserted into the polyethylene tubing before installing the tubing into the ﬁ tting elbow. Hand tighten only.

CAUTION

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

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

• On plastic ﬁ ttings, use thread sealing tape only. Never use pipe sealant or pipe dope on plastic ﬁ ttings, as damage may occur.

Step 10

Install OVERFLOW LINE to brine tank OVERFLOW FITTING (Figure 2). Discharge of line must be lower than OVERFLOW FITTING. DO NOT INTERCONNECT OVERFLOW LINE WITH VALVE DRAIN LINE.

2-3

Step 11

IMPORTANT NOTE

Make certain BYPASS VALVE INLET and OUTLET KNOBS ARE IN “BYPASS” position. After all plumbing connections have been completed, open main water shut-off valve. Check for leaks and correct as necessary.

Step 12

Plug CONTROL VALVE POWER CORD into 120v/60Hz, non-switched power source and set the time of day (See Set Time of Day on Page 3-

5). Manually stage control to BACKWASH POSITION and then unplug power cord to prevent the unit from advancing automatically (see Manual Regeneration on Page 3-5).

Step 13

Partially open INLET knob on bypass valve (Figure 4). This will allow the unit to ﬁ ll slowly from the bottom up, reducing air entrapment. Allow unit to ﬁ ll slowly, failure to do so could result in loss of resin to the drain. Once a steady stream of water, no air, is ﬂ owing to drain the inlet and outlet knobs on the bypass can be fully opened.

Step14

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: Control Valve Programming and Regeneration, on how to set control valve for proper set up and regeneration settings.

IMPORTANT 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 or California required salt efﬁ ciency is desired.

SPECIAL SERVICE INSTRUCTIONS (FSCWS075ME-CAB Only):

Under normal circumstances removal of valve should not be required. However, if it must be removed, it can be done by disassembling the quick release clamp, and latch. Pressure should be relieved before attempting any disassembly. Upon reassembly, all o-rings should be lubricated with silicone grease. Reassemble clamp as shown in Figure 5. MAKE SURE ARROWS ON LATCHSIDE OF CLAMP ARE ALIGNED.
