    PROGRAMMING THE 700 FOR 5-CYCLE FILTER APPLICATIONS Manganese Greensand Systems Sizing FA Filters Potassium permanganate regenerating iron filters should be sized for the appropriate backwash and injector sizes. Backwash Controller Be sure to choose the appropriate backwash flow rate control (see Parts section) as recommended by your media manufacturer.
  • Page 41 For example, an average person uses 75 gallons of water per day. Four people living in a home use 300 gallons of water (75 gallons x 4 people) per day. Assume the incoming water has 10 ppm of iron. Now calculate the daily demand: multiply the gallons of water used per day (300) by the ppm of iron content (10) = 3000 ppm of daily capacity usage.

    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: Slots 1.

  • Page 46: Drive Motor

    To install control module: 1. Be sure the power is disconnected. 2. Check model. 3. Check routing of wires and plug them into the controller. Connectors will snap in place. Be sure that wires are properly managed through the clips on top plate. This will prevent the wires from being caught in Wire Clips the camshaft.

  • Page 47: Optical Sensor

    3. Reconnect wires. NOTE: It is not necessary to pre-position the camshaft or the motor. When the controller is powered up the camshaft will be rotated to the "home" position. Optical Sensor The optical sensor is mounted to the top plate. The camshaft cup rotates through the sensor and the slots are detected.

  • Page 48: Camshaft

    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.
  • Page 49 To remove camshaft: 1. Disconnect power to the unit. 2. Remove cover. 3. Remove motor. 4. Camshaft should be in the treated water position. Rotate counterclockwise as needed. 5. Use a screwdriver to hold open the #1 valve disc. NOTE: When replacing/removing camshaft, make sure not to damage or mis- align the optical sensor.

  • Page 50: Wiring Harnesses

    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 18 - Wire Harness Routing Do not run wires through holes in topplate.

  • Page 51: Microswitch (Optional Under The Cover)

    To install a wiring harness: NOTE: Start at the back of the valve and work toward the controller. This will place any slack behind the controller. Slack or loose wires can become tangled in the camshaft. 1. Depending on which harness is being installed, plug the connector Slot for motor and transformer into the motor or turbine.

  • Page 52: Microswitch (Optional - Front Of Camshaft)

    WARNING: The Autotrol valve is rated for low voltage (less than 48 volts) microswitch components only. Using a high voltage switch may result in damaged valves or fire and may interfere with electronic control function. To remove microswitch: 1. Disconnect power to the switch.

  • Page 53: Spring (Valve Discs)

    NOTE: The cam for this switch is adjustable. To have the microswitch activate at a different point in the cycle, rotate the cam as needed. To rotate the cam loosen the center screw, tighten when the cam is in the new position. Spring (Valve Discs) This spring is a one-piece metal spring that applies pressure to the valve discs holding them closed.

    6. Clip wires with plastic tie-wrap to ensure that the wires do not tangle in camshaft. Terminal Block (Optional) WARNING: The Autotrol valve is rated for low voltage microswitch components only. Using a high voltage switch may result in damaged valves or fire and may interfere with electronic control function.

  • Page 56: Top Plate

    NOTE: The Autotrol 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 57 To install the top plate: NOTE: All valve discs should be in position. Use the same screws that were removed to reassemble the top plate. WARNING: Follow the procedure to engage the screws with the existing threads. If the same threads are not used, the holding power of the screw is lost.
