MANUAL OVERVIEW How To Use This Manual This installation manual is designed to guide the installer through the process of installing and starting conditioners featuring the 700 Logix series controllers. This manual is a reference and will not include every system installation situation.
EQUIPMENT INSTALLATION General Warnings And Safety Information The 268 and 255 water conditioner’s control valve conforms to NSF/ANSI 44 and 61 for materials and structural integrity only. Generic systems were tested and certified by WQA as verified by the performance data sheet. Electrical There are no user-serviceable parts in the AC adapter, motor, or controller.

WARNING: The inlet water must be connected to the inlet port of the valve. When replacing non-Pentair Water valves, the inlet and outlet may be reversed. It is also possible for the plumbing to be installed in an opposite order.
Figure 8 Drain Line Connection Right Way Air Gap Drain NOTE: Waste connections or drain outlet shall be designed and constructed to provide for connection to the sanitary waste system through an air-gap of 2 pipe diameters or 1 inch (22 mm) whichever is larger. WARNING: Never insert drain line directly into a drain, sewer line, or trap (Figure 8).
Figure 9 Overflow Line Connection Overflow Fitting Drain Tubing Secure hose in place Air Gap Drain Regenerant Line Connection (not used with 3-cycle filter system) The regenerant line from the tank connects to the valve. Make the connections and hand tighten. Be sure that the regenerant line is secure and free from air leaks.

Figure 11 Regenerant Connection for Performa Valve Regenerant Line Connection NOTE: Be sure to use plumbing connection tube when attaching regenerant line connections to the Performa valve. NOTE: When installing a 3-cycle filter (253 or 263 valve) use a cap on the regenerant line connection to prevent water seepage from the port.
Figure 12 Regenerant Tank Check Valve (not provided)* * Furnished as an option from conditioner system manufacturer. Electrical Connection CAUTION: This valve and control are for dry location use only unless used with a Listed Class 2 power supply suitable for outdoor use. All 700 Series controllers operate on 12-volt alternating current power supply.
100 VAC, 120 VAC and 230 VAC AC Adapters: Make sure power source matches the rating printed on the AC adapter. 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.

SYSTEM DISINFECTION Disinfection Of Water Conditioners The materials of construction of the modern water conditioner will not support bacterial growth, nor will these materials contaminate a water supply. During normal use, a conditioner may become fouled with organic matter, or in some cases with bacteria from the water supply.
GENERAL 700 SERIES INSTRUCTIONS 700 SERIES CONTROLLER Power Loss Memory Retention The 700 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.
Page 26
Variable Reserve Function The 700 Series metered-demand volumetric controllers (760 and 760C) 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.

PLACING CONDITIONER INTO OPERATION (turning on the water) Conditioner and FA Filter Start-Up After you have performed the previous initial power-up steps, you will need to place the conditioner into operation. Follow these steps carefully, as they differ from previous valve instructions. WARNING: Do not rotate the camshaft by hand or damage to the unit may occur.

If the tank has a salt platform in the bottom of the tank, add water until the water level is approximately 1 inch (25 mm) above the platform. NOTE: We recommend that you do not put regenerant into the tank until after the control valve has been put into operation.

hose connections. C2 should be displayed. 8. If the water level is receding from the regenerant tank you can then advance the controller back to the treated water (C0) position by pressing SET and the UP buttons simultaneously to advance the controller to the C0 position.
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 38
demand: multiply the gallons of water used per day (300) by the ppm of iron content (10) = 3000 ppm of daily capacity usage. Now take the system capacity (10,000), divided by the daily demand (3,000) = 3.3 days of capacity. Since you will run out of capacity before the beginning of the fourth day, the proper setting for days between regeneration is 3 days.

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.
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.
Optical Sensor The optical sensor is mounted to the top plate. The camshaft cup rotates through the sensor and the slots are detected. A signal is sent to the controller for each slot. NOTE: Damaged sensors should be replaced. Sensors may be cleaned with compressed air or a soft brush.
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. WARNING: The camshaft slots are molded to exact dimensions.
Page 47
NOTE: When replacing/removing camshaft, make sure not to damage or mis-align the optical sensor. Hold the sensor in position while removing camshaft. 6. Move the camshaft backwards, away from the controller. 7. Lift the loose front end up and out. To install camshaft: 1.
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.
This switch is turned on/off by a cam lobe on the camshaft. Its function is to signal that the unit is in-service or out-of-service (regenerating). Microswitches are available as kits from Pentair Water or a standard microswitch can be used as well.
This cam can be adjusted to activate the microswitch at any time during the regeneration cycle. The front end cam switch is available as a kit from Pentair Water. WARNING: This switch will normally control an event on another piece of equipment.
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.
Relay (Optional) WARNING: The Pentair Water 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.
6. Clip wires with plastic tie-wrap to ensure that the wires do not tangle in camshaft. Terminal Block (Optional) WARNING: The Pentair Water 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.
The top plate holds the valve discs in place during operation. This plate is removed to allow cleaning and replacing the valve discs. NOTE: The Pentair Water valve discs are made from a chloramine resistant severe service rubber. The valve discs will usually not need to be changed.
Page 55
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.
