RECEIVING
Yourunitwasbuilt,packaged,andinspectedwithextremecare.Weshippedittoyouusing
carrierswetrustwithaproventrackrecordofcarefulhandling,goodcustomerservice,andon
timedelivery.Unfortunately,regardlessofalloftheseeffortssometimesaccidentshappenand
occasionallythoseaccidentsresultinshippingdamage.Whenthecarrierpickedupthe
merchandisefromus,theyassumedresponsibilityforitsconditionenroutetoyou.Thus,any
claimsforshippingdamagemustbefiledwiththecarrier.Likeanybodyelse,carriersdon’tlike
topayoutoninsuranceclaims,sotheirclaimsproceduresandrequirementsarevery
restrictive.Youshouldconsultthecarrier’swebsitefortheirspecificclaimsprocedures.You
shouldalsoknowthattimeisoftheessence.
Therearetwogeneraltypesofshippingdamage.Thefirstisvisibledamage.Thistypeof
damageincludesvisibleloss,damage,shortageoranyexternalevidenceoflossordamagethat
isvisibleattimeofdelivery.Thistypeofdamagemustbenotedindetailonyourdelivery
receipt.Makesurethedriversignsanddatesthedeliveryreceipt,acknowledgingthe
damage.Thishastohappenatthetimeofdeliveryoritwon’thappenatall.Keepacopyfor
yourrecordsandsendanothertothecarrier’sdamageclaimsdepartmentalongwithaformal
requestforaninspectionreport.Followupwithaphonecall.Theircontactinformationcanbe
foundonthecarrier’swebsite.
Thesecondtypeofshippingdamageisconcealeddamage.Thistypeofdamagewillprobably
notbeapparentattimeofdeliveryandmaynotbediscovereduntilunpackingandinspecting
theunit.Remember,timeisoftheessencehere.Youshouldunpackandinspecttheunitas
soonaspossible.Eachdaythatpassesreducesthelikelihoodthatthecarrierwillpaytheclaim.
Assoonastheconcealeddamageisdiscovered,stopunpackingandretainallpacking
materials.Contactthecarrierbyphonetoreporttheclaim.Notethedateandtimeand
personyouspokewith.Getaclaimnumber.Followupwithawrittenletterreferencingthe
claimnumberandincludingaformalrequestforaninspection.Again,consultthecarrier’s
websiteforspecificclaiminstructionsandfollowthemprecisely.

ASSTATEDABOVE,THECARRIERISYOURSOLESOURCEFORSATISFACTIONOFADAMAGE
CLAIM.UNDERNOCIRCUMSTANCESSHOULDTHEMERCHANDISEBERETURNEDTOTHE

thescrew‐typeadjustableleveling
legsonthefrontcornersoftheunit.Turncounterclockwisetoraisethecorner;turn
clockwisetolowerit.Levelinglegsarerequiredinfrontonly.Unitmayhaveaslighttilt
fromfronttobackafterlegsareinstalled.Thisisacceptableandisrecommendedonthis
unit.

POWERSOURCE–Thesupplycircuittothiscabinet
mustconformtoallNationalandLocalElectrical
Codes.ConsultthecabinetSerial‐Dataplatefor
voltage,cycle,phase,andamprequirementsbefore
makingconnection.VOLTAGESHOULDNOTVARY
MORETHAN5%FROMSERIALPLATERATINGS.A
separatecircuitisrecommendedtopreventpossible
lossofproductduetoover‐loadingorfailureofotherequipmentonthesamecircuit.
PROTECTTHECIRCUITWITHA20AMPDELAY‐TYPE
FUSEORCIRCUITBREAKER.Donotuseanextension
cord.Besureyourunitisproperlygrounded.Usethe
3‐prongplugprovidedintoa3‐pronggroundedoutlet.
(Onlythismethodcomplieswithnationalelectrical
codes,localcodesandordinances.)Unlesstheabove
groundingmethodisfollowed,youarenotprotected
againstsevereorlethalshockintheeventofashort


appliance,allowthecabinettooperateaminimumoffourhoursoruntilithasstarted
cyclingnormallybeforeplacingproductinthecabinet.Themotorcompressormaystart
andstopseveraltimeswhentheunitisfirststartedorafterdefrosting,especiallyifthe
weatherisveryhot.Thisisonlynormalfunctioningofthemotoroverloadprotector.The
motorcompressorwillcyclenormallyassoonastheexcessheathasbeenremoved.

RefrigeratorOperation
Aftertheunitisproperlyinstalledandpowerisapplied,itwilltakesometimebeforethe
systemiscooleddowntotemperatureandcyclingnormally.Youshouldwait8hoursonthe
firststartupbeforebeginningtoaddproducttotheunit.Thisensuresthattheunitisinstalled
andoperatingproperlybeforebeingputintoserviceAfterthiswaittime,theunitshouldbe
cyclinginthedesigntemperaturerange.Theunitsarecalibratedbeforeleavingthefactory,so
noadjustmentshouldbenecessary.
Loadingtheunitswillagaincausetemperaturetoriseasthewarmerproductisintroducedinto
thecompartment.Ifalargeamountofproductistobeintroduced,itisagoodideatodoitin
stages,allowingseveralhoursbetweenstagestoallowtemperaturetostabilizeagainbefore
introducingadditionalwarmproduct.Thiswillminimizethetemperaturetransientwhile
loading.Othertipsforsuccessfulloadinginclude:
‐Leaveabout2‐3inchesoffreespacealongthebackandsidesoftheunittoallowforproper
airflowand,therefore,moreevencoolingoftheproduct.
‐Whenloadingthetopshelf,avoidblockingtheevaporatorfan(s)(ifinstalled).Thereshould
beatleast4inchesofclearancearoundthefantoallowproperairflow.
‐Donotoverloadtheunit.Afullloadisabout70%full.Additionally,theloadshouldbe
distributedevenlyfromtoptobottomandsidetosideforbestresults.
‐Minimizethetimethedoorisopen.Ontopoflettingthecoldairout,youarealsoletting
warm,moistairinwhichcanresultinmorecondensationand/orfrostintheunit.
Rememberthattheunitsarecalibratedtothedesigntemperaturerangebeforeleavingthe
factory.Wealsodoextensivetestingtoensurethatthesetemperatureswillresultinproduct
temperaturesinthedesiredband.Thereshouldbenoneedtoadjustthetemperaturecontrol
ontheseunits,butifitisnecessary,theycanbeadjustedusingtheelectronictemperature
controlonthefrontoftheunit.
ItisSTRONGLYRECOMMENDEDthatyoucontactthemanufacturer’sTechnicalSupport
Departmentpriortoperforminganytemperatureadjustmentstoensuretheadjustmentis
necessaryand,ifso,itisperformedcorrectly.

TempTech‐2000ElectronicTemperatureControl
DescriptionandFunctions

TheT‐1000ElectronicTemperatureControlisadigitalmicroprocessorbasedtemperature
control,indication,andalarmsystem.Itcontinuouslymonitorsthetemperatureofthe
refrigerator/freezerthroughitssensorassembly.Whenthetemperaturewarmstothepoint
whereitreachestheuppertemperaturelimit,thecontrollersendsasignaltoturnonthe
compressor,whichcoolstheunit.Thesnowflakeiconwillilluminateonthedisplay.The
compressoriskeptrunninguntilthetemperaturereachesthecoldsetting.Whenthislower
temperaturesetpointisreachedthecontrollerturnsoffthecompressorandthesnowflake
iconextinguishes.Therefrigerator/freezerwarmsovertimeandtheprocesscontinues.

TheT‐1000alsoprovidesthefollowingfunctions:
RedLEDforvisualindicationofanalarmcondition
Beeperforaudibleindicationofanalarmcondition
Apreprogrammed5minutedelayfromthetimeasetpointisattaineduntilanalarm
conditionisdeclared.Thispreventsspuriousalarmsforthingslikedooropenings.
Achoiceofremotealarmcontacts,onenormallyopenandonenormallyclosedfor
connectingremotealarmsorannunciationsystems.

QuickTroubleshootingGuide
Checktheseitemsbeforecallingforservice
PROBLEM: POSSIBLECAUSE/SOULTIONS:
Unitdoesnotrun

Electricalcircuitisnot110‐120V60Hz.
Thepowercordisnotpluggedin.
Nopoweratelectricaloutlet.Checktomakesure
breakerisnottrippedorfuseisnotblown.Additionally,
makesureunitisnotpluggedintoaGroundFaultCircuit
Interrupter(GFCI)typeofoutlet.
Unitdoesnotmaintainatthe
propertemperature

Checktheroomtemperature.Werecommendthe
refrigeratororfreezershouldbeplacedintheair
conditionedroombetween65°Fto85°F.Iftheroom
tempistoowarm,therefrigeratororfreezermaynotbe
abletomaintaintheinteriortempatproperrange.
Doorisnotclosedproperly.
Amountofstoredproductisoverloaded.
Productreplacementsarepushedagainstrearwallor
interruptedtheproperrefrigeratoraircirculation.For
theproperaircirculation,placetheproductsevenlyon
eachshelf.Donotpushagainsttherefrigerator’srearor
sidewalls.
Evaporatorisblockedbyfrostorice.Removethe
products,unplugtherefrigeratororfreezerpower,and
allowtheunittodefrost.Iftheproblemstillexists,call

Appliancerunstoolong

Prolongdooropenings.
Controlsettoocold.
Roomtemperatureishighwhichwillmaketheunitwork
hardertokeepcool.
Temperatureofexternalwall
surfaceiswarm

Theexteriorwallscanbeasmuchas30degreeswarmer
thanroomtemperatureduetotheembedded
condensercoils.Thisisnormalwhentheunitis
operating.
Compressornoises

Checktheunitlevel.Alsoensurenoneofthepipesin
thecompressorareaaretouchingeachotheroragainst
theside.
Compressormaybeoverheated.Pleasechecktheroom
tempandensuretherangeiswithin65°Fto85°F.
Abuzzingnoisemayindicateimpropervoltagetothe
compressor.Checksupplyvoltage.
Iftheproblemstillexists,callforservice.
