5. INSTALLING
A. RECEIVING
Eachunitiscompletelytestedunderoperatingconditionsandthoroughlyinspectedbefore
shipment.Atthetimeofshipment,thecarrieracceptstheunitandanyclaimfordamagemust
bemadewiththecarrier.Uponreceivingunit(s)fromthedeliveringcarrier,carefullyinspect
cartonforvisibleindicationofdamage.Ifdamageexists,havecarriernotesameonbilloflading
andleaclaimwiththecarrier.
B. UNPACKING
1. Removeshippingbasefromunitbymovingunitsothatonesideisoffthecountertoportable
allowingaccesstoscrewsonthebottomofshippingbase.
2. Assemblelegsbyliftingunit.DONOTLAYUNITONITSSIDEORBACK.
3. Removesplashplatebypullingupwardandforwardatthebottom.Driptraycannowbe
assembledbyattachingbracketandscrewstofrontofunit.
4. Dropdriptrayintobracket.Attachsplashplatebypushingupintofaucetplateandonto
standoffs.

3
NOTE:
Ifunitistransported,itisadvisabletoleaveunitsecuredtoplywoodshippingbase.
5. Inspectunitforconcealeddamage.Ifdamageexists,notifydeliveringcarriernoteandlea
claim against the carrier.
C. INSTALLATION
Thedispenserisdesignedtositonaat,supportedsurfacecapableofsupportingaminimum
weightof200pounds(90.7kg).Itmaybeeithercounterorlegmounted.Whenthedispenseris
to be permanently bolted to the countertop, seal dispenser base to countertop with a silicone
sealant, which provides a smooth and easily cleanable bond to the countertop.
NOTE:
NSFlistedunitsmustbesealedtothecountertoporhavefour(4)inchlegsinstalled.
WARNING
FAILURE TO MAINTAIN PROPER AIR CLEARANCE WILL CAUSE THE COMPRESSOR TO
OVERHEAT AND WILL RESULT IN PREMATURE COMPONENT FAILURE.
1. Position dispenser on countertop.
IMPORTANT
LOCATE DISPENSER TO ALLOW APPROXIMATELY 15 INCHES (380 MM) OF UNOBSTRUCTED
SPACE ABOVE AND SIX (6) INCHES (152 MM) OF UNOBSTRUCTED SPACE IN BACK OF
THE UNIT FOR PROPER AIR CIRCULATION AND REMOVAL OF BONNET. AIR IS DRAWN IN
THROUGH BACK GRILL AND IS EXHAUSTED OUT THE TOP GRILL.
2. Removebonnetfromthedispenser.
3. Removeinsulationstripfrominfrontofrefrigerationdeck.Filltankwithwateruntilwatercomes
outofoverowtube.Replaceinsulation.Usebottledwaterwherewaterproblemexists.
NOTE:
Thewaterbathcompartmentmustbelledwithwaterbeforeconnectingtoelectricalpower.
Otherwise, the compressor deck may not operate properly.
D. CONNECTING TO ELECTRICAL POWER
WARNING
THIS UNIT MUST BE PROPERLY ELECTRICALLY GROUNDED TO AVOID
POSSIBLE FATAL ELECTRICAL SHOCK OR SERIOUS INJURY TO THE OPERATOR. THE
POWER CORD IS PROVIDED WITH A THREE-PRONG GROUNDED PLUG.
IF A THREE-HOLE GROUNDED ELECTRICAL OUTLET IS NOT AVAILABLE,
USE AN APPROVED METHOD TO GROUND THE UNIT.
DO NOT USE EXTENSION CORDS WITH THIS UNIT. DO NOT “GANG” TOGETHER WITH OTHER
ELECTRICAL DEVICES ON THE SAME OUTLET.

4
1. Checkthedispenserserialnumberplateforunit’scorrectelectricalrequirements.Donotplug
intoelectricaloutletunlessunitelectricalconguration,locatedonserialplate,agreeswith
local available power supply.
2. Routethepowersupplycordtoagroundedelectricaloutletofthepropervoltageand
amperagerating,andplugintheunit.Thiswillturnontherefrigerationsystemandallowitto
startcoolingandallowicebanktoformwhilecompletinginstallation.Approximatelyfour(4)
hoursarerequiredtoformafullicebank.
NOTE:
Unitsequippedwithanelectronicicebankcontrolcontainatwenty(20)seconddelay.
Compressorandfanmotorwillnotbeginrunninguntiltwenty(20)secondsaftertheunitisplugged
into an electrical outlet.
E. CONNECTING SUPPLY LINES TO SOURCES
1. Removesplashplatefromfrontofdispenser.Liftslightlyandpullout.

seconds.Dividenumberofounces(ml)ofwaterincupbyfour(4)todeterminewaterowrate
persecond.Toobtainthedesiredowrate,useascrewdrivertoadjustwaterowcontrol(see
Fig. 6.1)
H. Hold Brix cup under the syrup separator and dispense water and syrup into cup. Target the same
bandwidthontheBrixcup.Adjustvalvesasrequired.

6
residual product.
4. Filllineswithacaustic-based(low-subsiding,non-perfumed,andeasilyrinsed)detergent
solution.Thesolutionshouldbepreparedinaccordancewiththemanufacturer’s
recommendations, but should be at least two (2) percent sodium hydroxide. Make sure the
linesarecompletelylledandallowtostandforatleastten(10)minutes.
5. Flushthedetergentsolutionfromthelineswithcleanwater.Continuerisinguntiltestingwith
