SECTION 1: BEFORE INSTALLATION

CAUTION

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.

ELECTRICAL

There are no user-serviceable parts in the AC adapter, motor, or controller. In the event of a failure, these should be replaced.

1) All electrical connections must be completed according to local codes.

2) Use only the power AC adapter that is supplied.

3) The power outlet must be grounded.

4) To disconnect power, unplug the AC adapter from its power source.

MECHANICAL

1) Do not use petroleum based lubricants such as petroleum jelly, oils, or hydrocarbon based lubricants. Use only 100% silicone lubricants.

2) Take care when using pliers or pipe wrenches to tighten plastic ﬁ ttings, as damage may occur if over tightening occurs.

3) All plumbing must be completed according to local codes.

4) Soldering near the drain line should be done before connecting the drain line to the valve. Excessive heat will cause interior damage to the valve.

5) Observe drain line requirements.

6) Do not use lead-based solder for sweat solder connections.

7) The drain line must be a minimum of 1/2 inch diameter. Use 3/4 inch pipe if the backwash ﬂ ow rate is greater than 7 gpm (26.5 lpm) or the pipe length is greater than 20 ft (6 m).

8) Do not support the weight of the system on the control valve ﬁ ttings, plumbing or the bypass.

9) It is not recommended to use sealants on the threads. Use thread tape on the threads of the 1 inch NPT elbow, the drain line connections, and other NPT threads.

1-1

GENERAL

1) Observe all warning and caution statements that appear in this manual.

2) Keep the media tank in the upright position. Do not turn upside down or drop. Turning the tank upside down will cause media to enter the valve.

3) Operating temperature is between 40°F (4.4°C) and 110°F (43.3°C).

4) Rated water pressure range is 20 - 125 psi.

CAUTION

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

• Installation and use MUST comply with existing state or local plumbing codes.

• Do not install on hot water supply lines. The maximum operating water temperature of this ﬁ lter system is 110°F (43.3°C).

5) Use only regenerant salts designed for water softening.

IMPORTANT NOTE

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

6) Follow state and local codes for water testing.

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.

7) When installing the water connections (bypass or manifold) connect to the plumbing system ﬁ rst. Allow heated parts to cool and cemented parts to be set before installing any plastic parts. Do not get primer or solvent on o-rings, nuts or the valve.

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.

CAUTION

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.

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

2-1

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.

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 softener is more than 15 lbs. Models utilizing 15” x 15”

x 34” brine tanks require salt grid extension legs when salting the softener above 15 lbs. of salt or more. 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 public water supply. 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) 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.

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.

The control valve allows for 1/2” connection 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 6) 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:

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 with local code ofﬁ cials prior to installation.

Step 7) 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 2). DO NOT raise DRAIN LINE more than 10 ft. above ﬂ oor.

Step 8) 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 pliers or wrenches to tighten as damage may occur and will void the manufacturer’s warranty.

Drain Line Connection

Figure 2

Step 9) Install OVERFLOW LINE to brine tank OVERFLOW FITTING. Discharge of line must be lower than OVERFLOW FITTING. DO NOT INTERCONNECT OVER-

FLOW LINE WITH VALVE DRAIN LINE.

2.2

Step 10) 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 and restore power to well pump. Check for leaks and correct as necessary.

Figure 3

Step 11) Plug CONTROL VALVE POWER CORD into 110v/60Hz, non-switched power source. Program the control valve (refer to page 3-1).

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.

Step 12) Manually stage control to BACKWASH POSITION. Press and hold REGEN button for 3 seconds. The valve will advance to BACKWASH POSITION.

Unplug power cord to prevent the unit from advancing automatically.

Step 13) Partially open INLET knob on bypass valve (Figure 3). 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 (refer to Figure 3).

Step 14) 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: Programming, on how to set control valve for proper set up and regeneration settings.

SPECIAL SERVICE INSTRUCTIONS:

Under normal circumstances removal of valve should not be required. However, if it must be removed, it can be done by rotating the valve head

assembly to the left or counter-clockwise. Pressure should be relieved before attempting any disassembly. 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.

2-3

BRINE LINE CONNECTION

The brine line to the brine tank connects to the valve. Make the connections and tighten (See Figure 4). Be sure that the brine line is secure and free from air leak. Even a small leak may cause the brine line to drain out, and the conditioner will not draw brine from the tank. This may also introduce air into the valve causing problems with valve operation.

ELECTRICAL CONNECTION

All AWS controllers operate on 12-volt alternating current power supply. This requires use of the supplied AC adapter.

Figure 4

AC ADAPTERS

Make sure power source matches the rating printed on the AC adapter.

IMPORTANT NOTE

The power source should be constant. Be certain the AC adapter is not on a switched outlet. Power interruptions longer than 8 hours may cause the controller to lose the time and day settings. When power is restored, the day and time settings must then be reentered.

CAMSHAFT

The front end of the camshaft has an indicator cup. The cup has slots in the outer periphery and numbers on the inside face. The numbers can be seen with the cover off, from the front over the top of the controller. The number at the top indicates which regeneration cycle is currently in progress (See Figure 5).

CAMSHAFT FRONT END

The corresponding slot for the number is positioned at the optical sensor which is approximately 90 degrees out of phase.

Regeneration Cycle Indicators

C0 = Treated Water - normal operation mode

C1 = Backwash Cycle

C2 = Brine Draw Cycle

C3 = Slow Rinse Cycle

C4 = System Pause

C5 = Fast Rinse Cycle 1

C6 = Backwash Cycle 2

C7 = Fast Rinse Cycle 2

C8 = Brine Reﬁ ll

Figure 5

POWER LOSS MEMORY RETENTION

The AWS series controllers feature battery-free time and date retention during the loss of power. This is designed to last a minimum of 8 hours depending on the installation. The controller will continue to keep time and day in dynamic memory while there is no AC power.

The controller will not track water usage on volumetric demand controls in the event of a power failure.

All programmed parameters are stored in the static memory and will not be lost in the event of a power failure. These settings are maintained separately from the time and day settings.

Information entered or calculated by the controller is stored in two different ways:

A static memory will store:

Media volume

Regenerant setting

Time of regeneration

Days between regeneration

A dynamic memory with 8 hour retention will store:

Current day of week

Running clock

2-4

MOTOR

The controller uses a standard 12-volt AC motor that works with either 50 Hz or 60 Hz.

IMPORTANT NOTE

Water ﬂ ow to the valve can be turned on or bypassed when the controller is powered up for the ﬁ rst time.

VARIABLE RESERVE FUNCTION

The AWS metered-demand volumetric controllers are designed to have a variable reserve feature. This feature automatically adjusts the reserve to the end-user’s water usage schedule.

A variable reserve saves salt and water by only regenerating when absolutely necessary, and ensures enough soft water for typical high-water usage days.

Each day of regeneration the controller reviews the last four weeks of water usage for the same day of the week to determine if the remaining capacity is adequate for the next day of the week. If not, it will initiate an automatic regeneration.

DISPLAY ICONS

IMPORTANT NOTE

In normal operation and during programming, only a few of the icons will actually be displayed.

Figure 6

1) Days of the week. The ﬂ ag immediately below the day will appear when that day has been programmed as a day the system should regenerated (used with 7-day timer programming).
