Location SelectionOutdoor LocationsLocation of a water conditioning system is important.The following conditions are required:It is recommended that the Pro Elite conditioner beinstalled in a protected environment. Level platform or floor.Note: The Pro Elite System can be provided withoptional leveling feet that may be used on the twotanks. Order part number 4000409. Room to access equipment for maintenanceand adding regenerant (salt) to tank. Ambient temperatures over 34 F(1 C and below 120 F (49 C). Water pressure below 125 psi (8.62bar) and above 20 psi (1.38 bar). In Canada the water pressure mustbe below 100 psi (6.89 bar). Constant electrical supply to operate the control. Total minimum pipe run to water heaterof ten feet (three meters) to preventbackup of hot water into system. Local drain for discharge as close as possible. Water line connections withshutoff or bypass valves. Must meet any local and statecodes for site of installation. Valve is designed for minor plumbingmisalignments. Do not support weightof system on the plumbing. Be sure all soldered pipes are fully cooled beforeattaching plastic valve to the plumbing.When installing the water conditioning system outdoors,several items must be considered: Moisture – The valve and control are ratedfor NEMA 3 locations. Falling water shouldnot affect performance. The system is notdesigned to withstand extreme humidityor water spray from below. Examplesare: constant heavy mist, near corrosiveenvironment, or upwards spray from sprinkler. Direct Sunlight – The materials used will fadeor discolor over time in direct sunlight. Theintegrity of the materials will not degrade tocause system failures. Temperature – Extreme hot or cold temperatureswill cause damage to the valve or control. Freezingtemperatures will freeze the water in the valve. Thiswill cause physical damage to the internal parts aswell as the plumbing and conditioning resin. Hightemperatures will affect the control. The displaymay become unreadable but the control shouldcontinue to function. When the temperature returnsto normal operating limits, the display will reappear. A protective cover should assist with hightemperature applications. Insects – The control and valve have been designedto keep all but the smallest insects out of thecritical areas. Any holes in the top plate can becovered with duct tape. The top cover should beinstalled securely in place.WARNING: Dry location use only, unlessused with a Listed Class 2 Power Supplysuitable for outdoor use.Pentair Pro Elite Professional Series Water Treatment System Service Manual 7

Water Line and Bypass ConnectionsA bypass valve system should be installed on allwater conditioning systems. A model 1265 bypass isincluded with this system. The bypass valve isolatesthe conditioner from the water system and providesunconditioned water to service during routinemaintenance and servicing procedures. See Figure 5Model 1265 Bypass (Included) and Figure 6 Typical ThreeValve Bypass Configuration(Not provided by manufacturer).Note: Before turning on the water to the valve, rotatethe two handles on the bypass valve 2-3 times. This willhelp seat the O-rings and prevent leaking.Normal OperationOutInBYPA S SBYOutInIn BypassPA S SBYBYPA S SPA S SWater ConditionerWater ConditionerFigure 5 Model 1265 Bypass (Included)Normal OperationWater ConditionerIn BypassWater ConditionerFigure 6 Typical Three Valve Bypass ConfigurationWaterWater(Not provided by manufacturer)ConditionerConditioner12 Pentair Pro Elite Professional Series Water Treatment System Service ManualWARNING: Do not use tools to tightenplastic fittings. Over time, stress may breakthe connections. Hand tighten the nuts.WARNING: Do not use petroleum greaseon gaskets when connecting bypassplumbing. Use only 100% silicone greaseproducts when installing any Pro Elitebrand valve. Non-silicone grease maycause plastic components to fail overtime.WARNING: The inlet water must beconnected to the inlet port of the valve.When replacing non-Pro Elite valves,it is possible that the inlet and outletplumbing is installed in a reversedposition. Ensure that the plumbing isnot installed in the opposite order. Tankmedia may be pushed into the valve.

Drain Line ConnectionRegenerant Line ConnectionsThe regenerant line from the brine tank safety brine valve(Figure 11) connects to the valve. Make sure both safetyvalve tube fittings are tight. Make the connections andhand tighten.Note: Standard commercial practices are expressedhere. Local codes may require changes to the followingsuggestions. Check with local authorities beforeinstalling a water conditioning system.Note: Be sure that the regenerant line is secure and free1. The unit should be above and not more than 20 feet(6.1 m) from the drain. Use an appropriate adapterfitting to connect 1/2-inch (1.3 cm) plastic tubing tothe drain line connection of the control valve.from air leaks. Even a small leak may cause the regenerantline to drain out, and the conditioner will not draw regenerantfrom the tank. This may also introduce air into the valvecausing problems with valve operation.2. If the backwash flow rate exceeds 5 gpm (22.7 Lpm)or if the unit is located 20-40 feet (6.1 – 12.2 m) fromdrain, use 3/4-inch (1.9 cm) tubing. Use appropriatefittings to connect the 3/4-inch tubing to the 3/4-inchNPT drain connection on valve.Ensure that plumber tape pipe sealant is applied tothe 3/8-inch NPT regenerant line connection (Figure 1Standard Basement Before Installation. Cold water linesshown.)3. The drain line may be elevated up to 6 feet (1.8 m)provided the run does not exceed 15 feet (4.6 m) andwater pressure at the conditioner is not less than 40psi (2.76 bar). Elevation can increase by 2 feet (61 cm)for each additional 10-psi (.69 bar) of water pressureat the drain connector.4. When the drain line is elevated but empties into adrain below the level of the control valve, form a7-inch (18 cm) loop at the far end of the line so thatthe bottom of the loop is level with the drain lineconnection. This will provide an adequate siphon trap.Tie or wire the hose in place at the drain point. Alsoprovide an air gap of at least 1-1/2 inch between theend of the hose and the drain point.5. When the drain empties into an overhead sewer line, asink-type trap must be used.6. Secure the end of the drain line to prevent it frommoving.Regenerant Line ConnectionFigure 8Regenerant Line ConnectionTube FittingFigure 7 Drain Line ConnectionWARNING: Never insert drain line directlyinto a drain, sewer line or trap (Figure9). Always allow an air gap between thedrain line and the wastewater to preventthe possibility of sewage being backsiphoned into the conditioner.Figure 9 Salt Tank Safety Brine Valve andBrine Well AssemblyPentair Pro Elite Professional Series Water Treatment System Service Manual 13

Electrical ConnectionOverflow Line ConnectionIn the event of a malfunction, the regenerant tankoverflow will direct “overflow” to the drain instead ofspilling on the floor. This fitting should be on the side ofthe cabinet or regenerant tank, Figure 10.To connect the overflow line, locate the connection onside of the regenerant tank. Insert overflow fitting intotank and tighten with plastic thumbnut and gasket.Attach length of 1/2-inch (1.3 cm) I. D. tubing (not supplied)to fitting and run to drain. Do not elevate overflow linehigher than overflow fitting.Note: There are no user serviceable parts in the ACadapter, motor or the control board.The Demand control operates on a 12-volt alternatingcurrent power supply. This requires use of the PentairWater supplied AC adapter. AC adapters are availablefrom your supplier for different applications.They include:Do not tie into drain line of control unit. Overflow linemust be a direct, separate line from overflow fitting todrain, sewer or tub with an air gap at the drain.Regenerant Line OpeningOverflow FittingAC AdapterInput VoltageApplicationPart NumberStandardwall-mount230V, 50/60 Hzfor drylocations only1000813120V AC Adapters:Make sure power source matches the rating printed onthe AC adapter.Note: The power source should be constant.

System OperationRepressurization – Cycle C4Treated Water (Downflow)Pressure is balanced in the valve before continuing theregeneration.Untreated water is conditioned as it flows through theresin bed and up the riser.Fast Rinse (Downflow) - Cycle C5Water passes through the resin bed and up through theriser to drain. All remaining regenerant residual is rinsedfrom the resin bed.If the model selected at first start-up was 268r, thisis a system that will refill the salt tank at the start of aregeneration cycle. When a regeneration cycle begins,the salt tank is filled and brine is allowed to developbefore Cycle 1 starts.2nd Backwash (Upflow) – Cycle C6Flow is identical to C1 Backwash. The resin is reclassified.Backwash (Upflow) – Cycle C1Flow is reversed by the control valve, directed down theriser, up through the resin bed and sent to drain. The bedis expanded and debris is flushed to the drain.2nd Rinse (Downflow) - Cycle C7Regenerant Draw (Downflow) – Cycle C2*Regenerant Refill Last – Cycle C8Water passes through the injector and regenerant isdrawn from the regenerant tank. The regenerant isdirected to the resin bed. The hardness ions are displacedby sodium ions. Regenerant draw is completed when theair check closes.Refill last only occurs if the model s
