Page 4 GENERAL Observe all warning and caution statements that appear in this manual. 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. Operating temperature is between 34°F (1°C) and 110°F (43.3°C). Rated water pressure range is 20 - 100 psi.
Page 5 SECTION 2: INSTALLATION WATER LINE CONNECTION A bypass valve system should be installed on all water conditioning systems. Bypass valves isolate the conditioner from the water system and allow unconditioned water to be used. Service or routine maintenance procedures may also require that the system is bypassed. CAUTION To reduce the risk associated with property damage due to water leakage: •...
Page 6 BRINE LINE CONNECTION The brine line to the brine tank connects to the valve. Make the connections and tighten. 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.
Page 7 A dynamic memory with 8 hour retention will store: Current day of week Running clock 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.

Page 9 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. Regeneration Cycle Indicators C0 = Treated Water - normal operation mode (not displayed) C1 = Backwash Cycle...

Page 11 STARTUP 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 ﬁ lled and allows regenerant draw to be tested. See Motor Removal in Maintenance and Service of this manual for further instructions.
Page 12 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 index- ing. 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.
Page 13 SECTION 3: PROGRAMMING THINGS YOU MIGHT NEED TO KNOW • When the controller is ﬁ rst plugged in, it may display a ﬂ ashing hourglass and the message Err 3, this means that the controller is rotating to the home position. If the Err 2 is displayed, check that the incoming power frequency matches the controller.

Page 15 • 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.

Page 18 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. When installed, the cover provides NEMA 3 water protection. This protects from falling water up to 30 degrees from vertical. To remove cover: 1) Grasp side edges toward rear of the valve.
Page 19 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.
Page 20 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.
Page 21 WIRING HARNESSES The wiring harnesses are designed to ﬁ t 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. To remove a wiring harnesses: 1) Disconnect power to the unit.
Page 22 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.
Page 23 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.
Page 24 4) Place a second screw into the hole diagonally opposite the ﬁ rst screw and turn in but do not tighten. 5) Insert another screw into one of the remaining corners and turn it in. 6) The fourth screw goes into the hole diagonally opposite. Turn it in. Put the remaining screws in following the same crisscross pattern working from the ends toward the center.
Page 25 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.
Page 26 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. The following service start-up procedure can be used when the controller was programmed prior to servicing the unit and removing power.
