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

Temperaturecontrol
NOTE:Allofthesecontrolsarepresetatthefactorytoprovidethedesiredairandproduct
temperaturesinsideoftheunitsandrequirenofurtheradjustment.Pleasecontactthe
manufacturersTechnicalSupportDepartmentbeforemakinganyadjustmentstodetermineif
adjustmentisnecessaryand,ifso,tomakesureitisperformedproperly.
Bothrefrigeratorsandfreezershaveamanualthermostatlocatedinsidethemetallicsealedbox
nearthetoprearcorneroftheunit.Thisthermostatcontrolsthecompressor.Turningthe
thermostattowardsthehighernumberswillmaketheunitcolder.Lowernumberswillmakeit
warmer.Turningthethermostattotheoffor0positionwillturntheunitoff.Forcombounits
(refrigeratorandfreezer),thisthermostatcontrolsthecompressorbasedonfreezer
temperature.Temperatureintherefrigerationcompartmentiscontrolledbyventingairfrom
thefreezercompartment


RefrigeratorandFreezer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.
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
back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.
