Hose must have sufficient strengthto resist collapse under the atmospheric pressuredifferential that may occur while pump is running.It is important, even with a flooded suction condition,that proper pipe fittings are used so water isdelivered to impeller eye with a smooth flow andconsistent velocity. An isolation valve is used in a pressurized suctionpipe to permit servicing pump. Piping run and connection fittings should beproperly aligned and independently supported toreduce strain on pump case. If solids are present, a strainer should be used toprotect the pump.Suction pipe size should be at least one commercialpipe size larger than opening of pipe inlet. Flowvelocity should not exceed 8 ft./sec.Recommended

Installation Swimming Pool Pump Suction Connection11Suction RequirementsPump suction is hazardous and cantrap and drown or disembowel bathers. Do not useor operate swimming pools, spas, or hot tubs if asuction outlet cover is missing, broken, or loose.Follow the guidelines below for a pump installationwhich minimizes risk to users of pools, spas, and hottubs.Entrapment ProtectionThe pump suction system must provide protectionagainst the hazard of suction entrapment or hairentrapment/entanglement.Suction Outlet CoversOutlets Per PumpProvide at least two hydraulically balanced maindrains, with covers (see Page 10), for each swimmingpool pump suction line. The main drains (suctionfittings) must be at least three feet apart, nearest pointto nearest point.The system must be built so that it cannot operate withthe pump drawing water from only one main drain (thatis, there must be at least two main drains connected tothe pump whenever it is running). However, if two maindrains run into a single suction line, the single suctionline may be equipped with a valve which will shutoffboth main drains from the pump.All suction outlet covers must be maintained. Theymust be replaced if cracked, broken, or missing.More than one pump can be connected to a singlesuction line as long as the requirements above aremet.All suction outlets must have correctly installed, screwfastened covers in place.Water VelocityTesting and CertificationSuction outlet covers must have been tested by anationally recognized testing laboratory and found tocomply with the latest ASME/ANSI Specification forSuction Fittings For Use in Swimming Pools, Spas, HotTubs, and Whirlpool Bathtub Applications.An NSF certified hair and lint strainer must be installedwith the pump in order to comply with NSF Standard 50.The maximum water velocity through any suction outletmust be 1.5 feet per second. In any case, do notexceed the suction fitting’s maximum designed flowrate.If 100% of the pump’s flow comes from the maindrain system, the maximum water velocity in thepump suction hydraulic system must be six feet persecond or less even if one main drain (suction fitting) iscompletely blocked.

Start-up General Information15Check rotation:Starting:Before pump is put into operation, rotational directionmust be checked to assure proper performance ofpump. Refer to illustration on Page 16.Never run pump dry. Running pumpwithout water will overheat pump and damage internalparts. Always make sure pump is primed prior to startup.Hazardous voltage. Can shock, burn, orcause death. Disconnect power to pump beforeservicing.Do not attempt any wiring changes without firstdisconnecting power to pump.PRIMING:Pump priming is the displacement of air with waterin the pump and suction piping. Pump MUST BEcompletely filled with water when operating.Refer to Page 17 for instruction on the followingconditions:1. Suction lift with priming pump (water source belowpump).2. Suction lift with foot valve (water source belowpump).3. Flooded suction (water source above pump,or incoming water pressure is greater thanatmospheric pressure).Prime pump by one of the above procedures. Turnon power to pump. Slowly open discharge valve untildesired flow rate is achieved. Place the “Hand-Off-Auto”selector switch in the “Auto” position. The pump will bestarted automatically when the pilot device signals themotor starter.STOPPING:Pump will stop automatically when the pilot devicede-energizes the motor starter. Turn the “Hand-OffAuto” selector switch to “Off” position if you want to stopthe pump while it is running.

ClockwiseStart-up Determine Pump Rotationtaro16tion129Viewed fromthis direction36As viewedEngage start switch momentarily(bump motor) to observe rotationaldirection.Direction of Pump Rotation is determined by viewing liquid end of pumpfrom the back or shaft side, and not from looking into the impeller eyeor front of volute case. A rotation direction arrow is cast into the pumpbody and shows correct rotation.1129 0694NOTICE: This pump rotates clockwise.Electric Motors:Single Phase: Refer to wiring information on themotor plate to obtain proper rotation.Three Phase: If pump runs backwards, reverse anytwo leads coming off incoming power (L1, L2, L3)until proper rotation is obtained. Reverse L1 and L2,or L2 and L3, or L1 and L3. Pump running backward - Centrifugal pumps will stillpump liquids, however, GPM and head (dischargepressure) will be a fraction of the publishedperformance.

Slowly open butterfly valve (if used) until desiredflow is achieved.(Discharge Priming Valve will open automatically).

Maintenance Mechanical Shaft Seal18Lubrication:Mechanical seal:LIQUID END of pump requires no lubrication.Mechanical shaft seal is lubricated by the liquid beingpumped. Do not run dry!Adjustment or maintenance is normally not required.The seal is enclosed within the pump and is selfadjusting. Seal is cooled and lubricated by the liquidbeing pumped. Refer to Pages 20 and 21 for removaland replacement. Do not run dry!MOTOR bearings are lubricated at the factory.Re-lubrication at intervals consistent with the amountof use will provide maximum bearing life. Refer to motorInstruction Manual for proper motor lubrication andmaintenance instructions.Performance check:Periodically check the output of the pump. Ifperformance is noticeably reduced, refer toTroubleshooting Chart.OBSERVATIONAL MAINTENANCE:When the pump and system operation have beenstabilized, verify that pump unit is operating properly.Observe the following:Vibration: All rotating machines can be expected toproduce some vibration, however, excessive vibrationcan reduce the life of the unit. If the vibration seemsexcessive, discontinue operation, determine cause ofthe excessive vibration, and correct.Noise: When the unit is operating under load, listenclosely for unusual sounds that might indicate that theunit is in distress. Determine the cause and correct.Operating Temperature: During operation, heatis dissipated from the pump and the driver. After ashort period of time, the surface of the pump bracketwill be quite warm (as high as 150 F), which is normal.If the surface temperature of the pump bracket ordriver is excessive, discontinue operation, determinecause of the excessive temperature rise, and correct.Worn bearings will cause excessive temperatures andneed to be replaced. The pump unit is cooled by thewater flowing through it, and will normally be at thetemperature of the water being pumped.PUMP PROTECTIONCOLD WEATHER/WET WEATHER INSTALLATIONS:SYSTEM DRAINS: Provide drain valves to emptysystem, including pump case, to prevent freezingdamage.SHELTER: If possible, provide shelter for unit to protectfrom weather. Allow adequate space around pump unitfor service. When effectively sheltered, a small amountof heat will keep temperature above freezing. Provideadequate ventilation for unit when running. For severeweather problems, where other shelter is not practical, atotally enclosed fan-cooled enclosure can be consideredfor electric motors.CONDENSATION: When the temperature of metal partsis below dew point and the surrounding air is moist,water will condense on the metal surfaces and cancause corrosion damage. In severe situations, a spaceheater can be considered to warm the unit.
