UNPACKING
1.Uncratemachine and/orbin byremoving the staplesfromaround the bottomofcardboardcrate and lift off.
2.Remove boltsfastening the crateskidtothe bottomof the unit. If auxiliarylegshave been purchased for
the bin, they shouldbeinstalled at thistime.

LEVELING
1.1. If legsare used,adjust the leveling legsof the storage bin until the unitisleveland all four(4)legsare
insoldcontactwiththe floor.Leveling is veryimportant to obtain properdraining and tomaintainthe proper
level inthe waterpump pan of the icecuber.
Note:If thebinisto beinstalledflushtothefloor,thebinmustbe sealedtofloorwithanapproved
mastic suchas DowR.T.V.#732,734,orG.E.#102,108.Thisis anN.S.F.requirementand istherespon-
sibilityof theinstaller.
UNIT LOCATION
1.Allowatleastaminimumofsixinchesat the rearand side of the icemachine forproperairRHPcircula-
tion.
2.Thisunithasbeen designed tobeinstalled inanindoorlocation whichis clean and whichcan be adequate-
ly ventilated.The airand watertemperatures should neverexceed 100 Forfall below50 F.(Temperatures
above 100 Fwill cut the icemaking capacitybelowan economical level.Temperaturesbelow50 Fwill
causeamalfunction of thermostatic sensors).
3.The unitshouldbelocated where aircirculation isnotrestricted.The unitshould notbe located neara
kitchen grill.Airwhichcontainsgreasevaporswill depositgreaseonthe condenser.The condensershould
always be keptclean.
UNITSET--UP
1.Take off frontpanelofmachine and remove hardware bag and servicemanualenvelope.
2.Mount the icemakertothe top of the icestorage bin oradapterinthe properposition overthe ice drop
opening.The icemakermust then be sealed bothonthe outside and the inside bottomedgeswith an ap-
proved N.S.F.mastic such asDow R.T.V.#732,734,orG.E.R.T.V.#102,108 (Diagram2).Thisisan
N.S.F.requirementand the responsibilityof the installer.

The waterinletconnection tothe unitisa 3/8”maleflareconnection located at the rearof the icemachine.
WARNING:If the waterpressure exceeds50 pounds,awaterpressureregulatorshould be
installed inthe waterinletline between the watershut--off valve and the strainer.
Install areducerfitting on the shut--off valveto accommodatethe waterstainer,whichis supplied with eachice
machine and MUSTbe used.Thisis veryimportant forcleaning.Connecteither3/8”or1/2”coppertubing be-
tween the waterinlet fitting of the icemachine and the waterstrainer.
Forwatercooled units
Twowaterinletconnectionsare provided.One forthe icemaking (evaporator) section whichislocated on the
back of the machine and isa 3/8”flared connection.The otherisforthe watercooled condenser.

STARTINGTHEUNIT
Afterthe icecuberhasbeen unpacked and leveled and all plumbing and electricalconnectionshave been
made,start the unit, and check forproperoperation.
Acuberhasthree separatecircuits: the watercircuit, the refrigerantcircuitand the electricalcircuit.
1.Startchecking the watercircuitbymaking surethat there are not thread of flarejointleaks,eitheroutside
the unitorinthe compressorsection.Nextcheck the waterflowoverthe evaporatorand makesurethatall
holesinthe waterdistributorare open,(See Diagram5)and that thereisno undue splash orloss ofwater
intothe ice bin.

ifnecessary.
2.Check the refrigerantcircuitbymaking surethat the condenserfan isrunning.(Thiswill be evidentbyair
noise)Isthe compressor running? (Feelthe casing forvibration). Isthe evaporatorgetting cold?
3.Check bin--harvestswitch operation.)See procedureinmanual).

WATERTREATMENT
Depending on the watersourceforthe icemaker,watertreatmentmaybe necessaryto preventcalciumorlime
scale deposits,bad taste and odor,chlorine problems,aswell as slime growth. If theseconditionsexist, contact
yourCorneliusDistributororDealerforinformation on watertreatmentsystemsCorneliusoffers.
WINTERSTORAGE
If the unitistobestored in an area wherethe temperaturewill drop belowfreezing,itismostimportant thatall
waterlinesbe drained to prevent themfromfreezing and possiblerupture.
To blowout the waterline,disconnect the watersupplyat the cabinetinletand use airpressuretoforcethe wa-
terintothe water reservoirpan.This can then be removed fromthe waterpan.
CLEANINGTHEAIR COOLED CONDENSER COIL
In orderto produce at full capacity, the refrigeration condensermustbe keptclean.The frequency ofcleaning
will be determined by surrounding conditions.Agood maintenance plan callsforan inspection atleasteverytwo
months.
CAUTION:Condensercooling fins are sharp.Use carewhencleaning.
Clean the aircondensercoil fromthe back of the machine withavacuumcleaner.Remove all the accumulated
dust, lint, and dirt.
