TABLE OF CONTENTS SECTION DESCRIPTION 1 2 3 4 5 6 7 8 BEFORE INSTALLATION INSTALLATION PROGRAMMING SERVICE INSTRUCTIONS & MAINTENANCE PERFORMANCE DATA SHEET TROUBLESHOOTING PARTS LIMITED WARRANTY 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.
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.
SECTION 2: INSTALLATION Proper installation sequence of water conditioning equipment is very important. Refer to the following diagram for your particular water supply. Failure to follow installation, operation, and maintenance instructions may result in property damage due to leakage and will void warranty.
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 fittings 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 fittings, never use pipe sealant or pipe dope.
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.
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.
MOTOR The controller uses a standard 12-volt AC motor that works with either 50 Hz or 60 Hz. IMPORTANT NOTE Water flow to the valve can be turned on or bypassed when the controller is powered up for the first 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.
21) Shows when water is flowing through the valve. 22) Used with #23, #24, #25. Displays a sequence number or a value. 23) History Values. The number displayed by #22 identifies which history value is currently displayed. 24) Parameter. Displayed only in Professional Programming. The number displayed by #22 identifies which parameter is currently displayed. 25) Cycle. The number displayed by #22 is the current cycle in the regeneration sequence. 26) Hardness setting.
REGENERATION MODES The AWS series controllers can be regenerated either automatically or manually. During a regeneration, the total time remaining of the regeneration, the total time remaining of the regeneration will be displayed on the controller. The current cycle is shown in the lower left of the display.
MANUAL REGENERATION Action Regen at next time of regen Key REGEN Duration P/R Display Recycle icon flashes Cancel regen REGEN P/R when recycle icon is flashing Recycle icon disappears Immediate regen REGEN 5 sec. Recycle icon appears Immediate double regen REGEN 5 sec. when immediate manual regen has started X2 icon appears The controller can be manually instructed to perform a regeneration.
START-UP IMPORTANT NOTE The control valve can be started-up even if power is not yet available to the controller. The valve must be connected to water supply. The motor can be unmounted from the valve, and the camshaft can be indexed manually counterclockwise by hand. This will allow the tank to be filled and allows regenerant draw to be tested. See Drive Motor of this manual for further instructions. 1) Remove the cover from the valve.
IMPORTANT NOTE As you advance through each cycle there will be a slight delay before you can advance to the next cycle. The hourglass icon will light while the camshaft is indexing. There may be a pause at cycle C4 (System Pause). This cycle allows the water/air pressure to equalize on each side of the valve discs before moving on. The hourglass will not be visible indicating that the system is paused.
SECTION 3: PROGRAMMING • When the controller is first plugged in, it may display a flashing hourglass and the message Err 3, this means that the controller is rotating to the home position (FIgure 14). If the Err 2 is displayed, check that the incoming power frequency matches the controller. See the Troubleshooting section of this manual. • The preset default time of regeneration is 2:00 AM. If you want to change it, see the instructions in “Basic User Programming”.
This level of programming is accessible by pressing the SET button. The UP and DOWN arrows will step through the settings. Time of day Day of week Time of regeneration Number of days between regeneration (99 day calendar override timer) Amount of salt used per regeneration System capacity Hardness To make changes: • Time of day When the Time of Day is displayed, push SET. The time will flash. Use the arrow buttons to increase/decrease the time. Push SET to enter the selection.
• Calendar override The controller can be programmed to regenerate automatically from a 1/2 day to a 99 day frequency. The 1/2 day regeneration mode will regenerate at the “time of regeneration,” as well as 12 hours opposite from that time. For example, the controller will regenerate at 2:00 AM and at 2:00 PM on the same day. The default setting is 12 days. To change, push SET when this setting is displayed. Use the arrow buttons to increase/decrease. Push SET to enter the selection.
The following tables show the estimated salt amount for each setting, as well as the estimated capacity of that salt setting for each resin amount.

SECTION 4: SERVICE INSTRUCTIONS & MAINTENANCE VALVE SERVICE COVER The cover provides protection for the controller, wiring, and other components. This cover will be removed for most service and maintenance. To remove cover: 1) Grasp side edges toward rear of the valve. 2) Pull outwards until the slots in the cover clears the projections on the top plate. 3) Lift up on the rear and pull forward to clear the control module.
DRIVE MOTOR The drive motor is open loop and receives commands from the control module. The motor has a pinion gear that meshes with the camshaft gear to drive (rotate) the camshaft. During operation, rotation forces the motor into its mounting position and screws or bolts are not needed. NOTE: Some units will have a shipping peg in the top motor mount. The peg can be removed and discarded. This peg is not required for motor operation. To remove motor: 1) Disconnect power to the unit. 2) Remove cover.
CAMSHAFT The camshaft has several lobes that push open the valve discs as the camshaft rotates. Rotation is controlled by a drive motor that drives a gear at the rear of the camshaft. The front end has a cup with markings and slots. IMPORTANT NOTE The camshaft slots are molded to exact dimensions. Do not attempt to modify the cam cup slots. Improper regen will occur! The outside surface of the cup has an arrow mark. When the arrow is at top center, the camshaft is in the loading position.
WIRING HARNESSES The wiring harnesses are designed to fit one way. The connectors are unique to the port they plug into. The wires are held in place by clips and the connectors latch in place. Figure 31 To remove a wiring harnesses: 1) Disconnect power to the unit. 2) Remove cover. 3) Remove controller. 4) Remove connections by squeezing the latch on the connector and pulling out. Figure 32 5) Pull the harness out of the clips on the top plate.
SPRING (VALVE DISCS) This spring is a one-piece metal spring that applies pressure to the valve discs holding them closed. The rotating camshaft overcomes this pressure to open the valve discs as needed. The shape of the spring is critical for proper operation. IMPORTANT NOTE Do not attempt to straighten or repair this spring. If this spring is damaged, valve discs may not operate correctly. To remove spring: 1) Disconnect power to the unit. 2) Remove cover. 3) Remove motor. 4) Remove camshaft.
TOP PLATE The top plate holds the valve discs in place during operation. This plate is removed to allow cleaning and replacing the valve discs. IMPORTANT NOTE The valve discs are made from a chloramine resistant severe service rubber. The valve discs will usually not need to be changed. Before removing the top plate for valve disc service be certain that one of the discs is not operating correctly. To remove top plate: 1) Disconnect power to unit. 2) Remove cover. 3) Remove motor. 4) Remove camshaft.
10) Replace camshaft and motor. 11) Replace controller and wiring harnesses. Figure 37 MAINTENANCE IMPORTANT NOTE: Many of the maintenance procedures involve o-rings. When reassembling two parts with an o-ring seal, care must be taken with the placement of the o-ring. To properly install o-rings, they should be lightly lubricated with silicone. Place the o-ring over the part feature that will be inserted into the hole. Do not start the assembly with the o-ring in the hole.
WATER METER MAINTENANCE Demand Systems The valve metering devices are used with the demand controls, and may require simple maintenance. In rare instances, the turbine wheel of the water meter can collect small particles of oxidized iron, eventually preventing the wheel from turning. 1) Shut off the water supply or put the bypass valve(s) into the bypass position. 2) Relieve pressure by opening the backwash drain valve (the seventh back from the controller) with a screwdriver.
AFTER SERVICE START-UP Whenever the controller is unplugged or the system is put in bypass for maintenance, a start-up is required. This start-up is not normally as extensive as the new system start-up procedure needs to be followed. The initial power-up procedure should be used if a new controller or a new valve has been installed. This procedure is explained in the users manual.
