max.
Useonlyasaguide.Duetoweightof
cable, pumping range above horizontal
isnotequaltopumpingrangebelow
horizontal. Ranges are based on testing in
nonturbulent conditions. Range may vary
due to water temperature and cord shape.
As tether length increases, so does the
variance of the pumping range.

THREE PHASE WIRING INSTRUCTIONS
FOR YOUR PROTECTION, ALWAYS
DISCONNECT PUMP FROM ITS POWER SOURCE
BEFORE HANDLING.
Toautomaticallyoperateanonautomaticthreephasepump,a
controlpanelisrequired.Followtheinstructionsprovidedwith
the panel to wire the system. For automatic three phase pumps,
see automatic 3 phase wiring diagram located to the far right.
Beforeinstallingapump,checkthepumprotationtoensurethat
wiring has been connected properly to power source, and that
thegreenleadofpowercord(seewiringdiagram)isconnected
to a valid ground. Momentarily energize the pump, observing the
directionsofkickbackduetostartingtorque.Rotationiscorrectif
kickbackisintheoppositedirectionofrotationarrowonthepump
casing. If rotation is not correct, switching of any two power leads
other than ground, should provide the proper rotation.
Allthreephasepumpsrequiremotorstartingdeviceswithmotor
overloadprotection.SeeFM0486forduplexinstallations.Pumps
mustbeinstalledinaccordancewiththeNationalElectricalCode
andallapplicablelocalcodesandordinances.Pumpsarenotto
beinstalledinlocationsclassiedashazardousinaccordance
withNationalElectricalCode,ANSI/NFPA70.

SINGLE PHASE WIRING INSTRUCTIONS
FOR YOUR PROTECTION, ALWAYS DISCONNECT PUMP FROM ITS POWER SOURCE BEFORE HANDLING. Single phase pumps
aresuppliedwitha3-pronggroundedplugtohelpprotectyouagainstthepossibilityofelectricalshock.DO NOT, UNDER ANY CIRCUMSTANCES,
REMOVE THE GROUND PIN.The3-prongplugmust beinsertedintoamating3-pronggroundedreceptacle.If the installation does not have such
areceptacle,itmustbechangedtothepropertype,wiredandgroundedinaccordancewiththeNationalElectricalCodeandallapplicablelocalcodes
and ordinances.
Risk of electrical shock. Do not remove power supply cord and strain relief or connect conduit directly to the pump.
Installationandcheckingofelectricalcircuitsandhardwareshouldbeperformedbyaqualiedlicensedelectrician.
Unitssuppliedwithoutaplug(singleandthreephase)andsinglephasenonautomaticunitswitha20ampplugmusthaveamotorcontrol
andliquidlevelcontrolprovidedattimeofinstallation.Thecontroldeviceshouldhavesuitablevoltage,ampere,frequency,groundingandhorsepower
rating for the pump to which it is connected.
IMPORTANT NOTICE: Someinsurancepolicies,bothcommercialandresidential,extendcoveragefordamagesincurredbyproductfailure.Youwillneedto
