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

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

Temperaturecontrol
NOTE:Thecontrolispresetatthefactorytoprovidethedesiredairandproduct
temperaturesinsideoftheunitandrequiresnofurtheradjustment.Pleasecontactthe
manufacturer’sTechnicalSupportDepartmentbeforemakinganyadjustmentstodetermine
ifadjustmentisnecessaryand,ifso,tomakesureitisperformedproperly.
Thisunithasamanualthermostatlocatedinsideofthecompartment.Thisthermostatcontrols
thecompressor.Turningthethermostattowardsthehighernumberswillmaketheunitcolder.
Lowernumbersmakeitwarmer.Turningthethermostattotheoffor0positionwillturnthe


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.Onsubsequentstartups(aftercleanings,
forexample),thiswaittimecanbereducedtoabout3hours.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belowthefan(s)toallowproperairflow.
‐Donotoverloadtheunit.Afullloadisabout70to75%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.
Theauto‐defrostmodelswillperiodically(usually2to4timesaday)gointoadefrostcycleto
removefrostbuild‐uparoundtheevaporatorcoils.Duringthiscycle,thecompressoristurned
offanddefrostheatersareturnedonintheevaporatorsection.Thiswillcauseatemperature
transientwhichwillbeseeninairtemperatureinsidetheunitbutshouldnotsignificantlyaffect
producttemperatures.
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manualthermostatonthe
inside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.

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


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
forservice.
3rdpartythermometerisplacedincorrectly.Forproper
temperaturemonitoring,thethermometershouldbe
placeinthemiddleofrefrigerator.
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

MoistureduringtheSummermonths
Theamountofmoisture,condensation,orhighhumidityrelatedissuesincreaseduringthesummer
and,inmostcases,willself‐resolvewhentheweathercoolsdown.Pleasenotearefrigeration
systemwillNOTgeneratemoistureorwaterbutsimplycondensesthemoisturethatisalreadyin
thechamber.Keepingtheunitinanairconditioned,lowhumidityspacewillresolvemanyissues.
Otherthingsyoushouldcheck:
1. Locationoftherefrigerator(SeeQuickTroubleshootingGuideabove)
2. Doorsealingandfrequencyofdooropeningevent(SeeQuickTroubleshootingGuideabove)
3. Makesurethereisawatertrap(U‐shapedloop)inthedraintubeneartheend.Thiswill
“trap”asmallamountofwaterintheloopandpreventairfromenteringthechamber
throughthetube.
