Wiring and GroundingWARNINGHazardous voltagecan shock, burn orcause death.WARNINGExtreme heat cancause personal injuryor property damage.Install, ground and wire accordingto local and NationalElectrical Code requirements.Install an all leg disconnectswitch near the pump.Disconnect and lockout electricalpower before installing orservicing pump.Electrical supply MUST match pump’s nameplatespecifications. Incorrect voltage can cause fire,damage to the motor and voids warranty.Motors equipped with automatic thermal protectionopen the motor’s electrical circuit when athermal overload exists. This can cause the pumpto start unexpectedly and without warning.Use only stranded copper wire to motor and ground.The ground wire MUST be at a least as large as the wireto the motor. Wires should be color coded for ease ofmaintenance.WARNINGHazardousvoltageFAILURE TO PERMANENTLYGROUND THE PUMP, MOTOR ANDCONTROLS BEFORE CONNECTINGTO ELECTRICAL POWER CANCAUSE SHOCK, BURNS OR DEATH.NOTICE: UNIT ROTATION IS CLOCKWISE, WHENVIEWED FROM THE MOTOR END.INCORRECT ROTATION MAY CAUSEDAMAGE TO THE PUMP AND VOIDS THEWARRANTY.OperationNOTICE: PUMP MUST BE FULLY PRIMEDBEFORE OPERATION.MaintenanceOPERATION AT OR NEAR ZEROFLOW CAN CAUSE EXTREME HEAT,PERSONAL INJURY OR PROPERTYDAMAGE.After stabilizing the system at normaloperating conditions, check the piping.If necessary adjust the pipe supports.Motors have permanently lubricated bearings. No lubricationis possible or necessary. Follow the motor manufacturer’srecommendations for maintenance.DisassemblyWARNINGHazardousvoltageWARNINGHazardous fluids cancause personal injuryor property damage.FAILURE TO DISCONNECT ANDLOCKOUT ELECTRICAL POWERBEFORE ATTEMPTING ANYMAINTENANCE CAN CAUSESHOCK, BURNS OR DEATH.CASING MAY CONTAINHAZARDOUS FLUIDS THAT CANCAUSE PERSONAL INJURY ORPROPERTY DAMAGE.Containing pumpage as required,remove pump casing vent and drainplugs (408). Remove and discard therespective plug O-rings. Drain and flushsystem, as required.Remove the four motor bolts from the motor base orfoundation.Remove the eight casing cap screws (370), then using theslots provided about the casing (100), pry the back pulloutassembly from the casing.Remove and discard the casing O-ring (513) and theinternal casing O-ring (349).NOTICE: IMPELLER COMPRESSES THEMECHANICAL SEAL SPRING – BEPREPARED FOR THE IMPELLER TOSPRING FROM SHAFT WHEN IMPELLERIS REMOVED.Remove the end cap from the motor, exposing a slot inthe end of the motor shaft. While holding the shaft fromrotation with a screwdriver, remove the impeller locknut(304) (if present) by turning it COUNTERCLOCKWISE.Remove impeller (101) by turning counterclockwisewhen looking at the front of the pump. Protect handwith rag or glove. Apply localized heat for 1-2 minutes orto an approximate temperature of 250º C. Disassemblewhile hot. Heating will decrease the break-loose torqueof the Loctite 243 and allow for easy removal.CAUTION Excessive heating may cause damage tothe seal. Seal replacement is recommendedif pump is disassembled or repaired.Using two pry bars, 180º apart, CAREFULLY separatethe seal housing (184) from the motor adapter (108).The mechanical seal (383) rotary assembly will slide fromthe motor shaft with the seal housing.CAREFULLY push out the mechanical seal stationaryseat from the seal housing. Inspect and wipe clean thestationary seat bore. Replace as necessary. DISCARD themechanical seal assembly.If necessary, remove the four motor hex bolts (371) andCAREFULLY slide the motor adapter from the shaft.Replace the motor assembly and deflector (123), asrequired.Disassembly is complete.
