DANGER
Do not attempt to install or perform maintenance on equipment while it is energized! Death,
personal injury or substantial property damage may result from contact with energized equip-
ment. Always verify that no voltage is present before proceeding and always follow generally
accepted safety procedures. Controller disconnect switch must be in the “off” position in
order to open the enclosure door. Tornatech cannot be liable for any misapplication or incor-
rect installation of its products.

INTRODUCTION
ElectricFirePumpcontrollersaredesignedtostartanelectricmotordrivenfirepump.Itcaneitherstart
thefirepumpmanuallythroughthelocalstartpushbuttonorautomaticallythroughthesensingofa
pressuredropinthesprinklersystem.Thefirepumpcontrollerissuppliedwithapressuretransducer.
Thefirepumpcanbestoppedmanuallywiththelocalstoppushbuttonorautomaticallyaftertheexpir-
ationofafieldprogrammabletimer.
Itisequippedwithanautomatictransferswitchthatfeedsthecontrollerfromeitherthenormalorthe
alternatepowersource.

Ifthecontrollerisnotinstalledandenergizedimmediately,Tornatechrecommendsfollowingthe
instructionsinchapter3ofNEMAICS15.
SEISMIC
ElectricFirePumpcontrollersareoptionallyseismicapprovedandhasbeentestedinaccordancewith
theICC-ESAC156,IBC2015&CBC2013standards.Properinstallation,anchoringandmountingis
requiredtovalidatethiscompliancereport.Refertothismanualanddrawingstodeterminetheseismic
mountingrequirementsandlocationofthecenterofgravity(youmayneedtocontactfactory).The
equipmentmanufacturerisnotresponsibleforthespecificationandperformanceofanchoragesys-
tems.Thestructuralengineerofrecordontheprojectshallberesponsibleforanchoragedetails.The
equipmentinstallationcontractorshallberesponsibleforensuringtherequirementsspecifiedbythe
structuralengineerofrecordaresatisfied.Ifdetailedseismicinstallationcalculationsarerequired,
pleasecontactthemanufacturerfortheperformanceofthiswork.
ENVIRONMENT
ElectricFirePumpcontrollersareintendedtobeinstalledinlocationswhereambienttemperaturesare
within4°Cand40°Candtherelativehumidityiscontrolledbetween5%and80%.Optionally,thecon-
trollercanhaveanextendedtemperatureofupto55°Candaslowas-5°C,providedthatthecontroller
andthepressurewaterpipesareheatedtopreventwaterfreezinganddamagingtheelectronicsand
thepipingsystem.
Theyareintendedforpollutiondegree3andshallbeinstalledatanaltitudeofnomorethan2000
meters.Forabnormalinstallationenvironment,consultfactory.
ELECTROMAGNETIC COMPATIBILITY (EMC)
ElectricFirePumpcontrollershavebeentestedforthemoststringentconditionsforemissions(Envir-
onmentB)andimmunity(EnvironmentA),hencecontrollerscanbeinstalledineitherenvironment.All
controllersvariantssharethesameelectronicsandcomplytothosecriteriawithoutrequiringadditional
measures.
HANDLING
TheweightofeachElectricFirePumpcontrollerisindicatedonthepackinglabel.Lightweightcon-
trollersdonotrequirespecialhandlinginstructions,whileheavycontrollersareequippedwithlifting

C22.1,CanadianElectricalCode,Article26.302oranyapplicablelocalcodes.
ThestandardcontrollerenclosureisratedNEMAType2.Itistheinstaller’sresponsibilitytoinsurethat
eitherthestandardenclosuremeetstheambientconditionsorthatanenclosurewithanappropriate
ratinghasbeenprovided.Controllersmustbeinstalledinsideabuildingandtheyarenotdesignedfor
outsideenvironment.Thepaintcolormaychangeifthecontrollerisexposedtoultravioletraysfora
longperiodoftime.
MOUNTING
TheElectricFirePumpcontrollershallbemountedinasubstantialmanneronasingleincombustible
supportingstructure.

V2024.02 9
FLOOR MOUNTING
Floormountedcontrollersshallbeattachedtothefloorusingallholesprovidedonthemountingfeet
withhardwaredesignedtosupporttheweightofthecontroller.Themountingfeetprovidetheneces-
sary12in.(305mm)clearanceforcurrentcarryingparts.
WALL MOUNTING
Refer to the controller dimension drawing for necessary mounting dimensions.
Thecontrolleriswallmountedbyusingatleastfour(4)wallanchors,2anchorsforthetopmounting
bracketsand2anchorsforthebottommountingbrackets.Thebracketsaredimensionallyonthesame
centerlineforeaseinmounting.Thereshouldbeaclearanceofatleast6inches(152mm)aroundthe
controllertoallowproperaircirculationaroundtheequipment.
1. Usingeitherthedimensionprintorbymeasuringthedistancebetweenthecenterlinesofthe
lowerbracketslots,transcribethisdimensionontothewall.Note:Thebottomedgeoftheenclos-
ureshouldbeaminimumof12”(305mm.)fromthefloorincasefloodingofthepumproom
occurs.
2. Drillandputanchorsintothewallforthelowermountingbrackets.
3. Markonthewall,thelocationoftheholesintheuppermountingbrackets.
4. Drillandputanchorsintowallfortheuppermountingbrackets.
5. Installboltsandwashersinloweranchors.
6. Alignholesinuppermountingbracketsandinstallboltsandwashersinanchors.
7. Shimanchorsasnecessarytoensurerearofenclosureisverticallevelandenclosureisnot
stressed.
8. Tightenallanchorbolts.
9. Checktobesureenclosuredooropenandclosesfreelyandthatenclosureislevel.
MAKING SYSTEM PRESSURE CONNECTIONS
Thecontrollerrequiresone(1)“SystemPressure”connectionfromthesystempipingtotheenclosure.
Theconnectionfitting,1/2”NPTmaleport,isprovidedontheleftexternalsideoftheenclosureforthis
purpose.RefertoNFPA20forcorrectfieldpipingprocedureofthesensinglinebetweenthepumping
systemandthecontroller.Ifadrainispresent,theconnectiontothedrainisataperedconnectionfor
plastictubing.
MAKING ELECTRICAL CONNECTIONS
TheelectricalwiringbetweenthepowersourceandthefirepumpcontrollershallmeettheNFPA20,
NFPA70NationalElectricalCodeArticle695orC22.1CanadianElectricalCode,Section32-200orany
applicablelocalcodes.Electricalwiringshallbetypicallysizedtocarryatleast125%ofthefullloadcur-
rent(FLCorFLA)ofthefirepumpmotor.

V2024.02 10
IMPORTANT PRECAUTIONS
Alicensedelectricianmustsupervisetheelectricalconnections.Thedimensiondrawingsshowthearea
suitableforincomingpowerandmotorconnections.Nootherlocationshallbeused.Onlywatertight
hubfittingsshallbeusedwhenenteringthecabinettopreservetheNEMAorIPratingofthecabinet.
The installer is responsible for adequate protection of the Electric Fire Pump controller com-
ponents against metallic debris or drilling chips. Failure to do so may cause injuries to per-
sonnel, damage the controller and subsequently void warranty.
Priortomakinganyfieldconnections
1. Opendoorofenclosureandinspectinternalcomponentsandwiringforanysignsoffrayedor
loosewiresorothervisibledamage.
2. Verifythatthecontrollerinformationiswhatisrequiredontheproject:
1. Tornatechcatalognumber
2. Motorelectricalnameplateinformationmatchescontrollerratingforvoltage,frequency,
FLAandHP.
3. Project'selectricalcontractormustsupplyallnecessarywiringforfieldconnectionsinaccordance
withtheNationalElectricalCode,localelectricalcodeandanyotherauthorityhavingjurisdiction.
4. Refertotheappropriatefieldconnectiondrawingforwiringinformation.
PROCEDURE
Allfieldconnections,remotealarmfunctionsandACwiringarebroughtintotheenclosurethroughthe
toporbottomconduitentrancesasindicatedonthedimensionaldrawing.

2. Installnecessaryconduit.
3. Pullallwiresnecessaryforfieldconnections,remotealarmfunctions,ACpowerandallother
optionalfeatures.Bringenoughwireinsidetheenclosuretomakeupconnectionstotheappro-
priateline,loadandcontrolterminalblockpoints.Besuretoconsulttheappropriatefieldcon-
nectiondiagramforconnectionpointsandacceptablewiresize.Forproperwiresizing,referto
theNationalElectricalCode,NFPA70.
4. Makeallfieldconnectionstotheremotealarmfunctionsandanyotheroptionalfeatures.
5. Connectmotortocontrollerloadterminals.
6. FindnameplateonElectricFirePumpmotorandmakenoteofitsfullloadamprating.
