General InformationSection 1BIN INSTALLATIONDISPENSER INSTALLATION All ice machines installed on a bin require an icedeflector. Manitowoc bins have a deflector installed and requireno modifications when used with a forward facingevaporator.No adapter is needed for machines that match thesize of the dispenser unless required by thedispenser manufacturer. 22" & 30" ice machines ship with the deflector/bafflerequired for dispenser usage. No additional deflector/baffle is required, unless specified by the dispensermanufacturer. A bin thermostat to control ice level is recommended. Ice machines with multiple evaporators require adeflector kit.LUMINICE The LuminIce growth inhibitor recirculates the air inthe ice machine foodzone over a UV bulb. This processwill inhibit the growth of common micro-organisms on allexposed foodzone surfaces. LuminIce bulbs require replacement on a yearlybasis. The control board can be set to automatically displaya reminder after 12 months. Refer to LuminIce insection 3 for setup procedures.Cleanup Procedure for Accidental Bulb BreakageThe cleanup procedure is identical to the procedureused to clean up compact fluorescent (CFL) orfluorescent tube lights. These lights contain a smallamount of mercury sealed within a glass tube. Breakingthese types of lights will release mercury and mercuryvapor. The broken bulb can continue to release mercuryvapor until it is cleaned up and removed.CONTROL PANEL BEZELThe ice machine ships with two bezels: The standard bezel allows the display screen to beviewed and the menu, arrows and checkmarkbuttons can be accessed. The key guard bezel allows the display screen to beviewed and covers all buttons to preventunauthorized settings from being entered. The icemachine door must be opened to access the controlpanel.To change the bezel, open the ice machine door, removethe two screws securing the bezel and slide the bezel tothe right while lifting forward.An optional cover that completely hides the display isavailable as a sales kit, and is available through yourlocal distributor or service company.The latest EPA procedures can be viewed on theirwebsite at www.epa.gov/cfl/cflcleanup.html.6Part Number 000007345 2/12

Installation InstructionsIce Machine Heat of RejectionSeriesIce 00I1400I1800I3300Heat of RejectionAir e the heat of rejection varies during the ice making cycle, the figure shown is an average.* Indicates Preliminary DataIce machines, like other refrigeration equipment, rejectheat through the condenser. It is helpful to know theamount of heat rejected by the ice machine when sizingair conditioning equipment where self-contained aircooled ice machines are installed.This information is also necessary when evaluating thebenefits of using water-cooled or remote condensers toreduce air conditioning loads. The amount of heat addedto an air conditioned environment by an ice machineusing a water-cooled or remote condenser is negligible.Knowing the amount of heat rejected is also importantwhen sizing a cooling tower for a water-cooledcondenser. Use the peak figure for sizing the coolingtower.Section 2Removing Drain Plug and Leveling the IceStorage Bin! WarningTo avoid instability the bin/dispenser must beinstalled in an area capable of supporting the weightof the bin/dispenser, ice machine and a full bin ofice. The bin/dispenser must be level side to side andfront to back before installing the ice machine.1. Remove threaded plug from drain fitting.2. Screw the leveling legs onto the bottom of the bin.3. Screw the foot of each leg in as far as possible.! CautionThe legs must be screwed in tightly to prevent themfrom bending.4. Move the bin into its final position.5. Level the bin to assure that the bin door closes andseals properly. Use a level on top of the bin. Turn thebase of each foot as necessary to level the bin.6. Inspect bin gasket prior to ice machine installation.(Manitowoc bins come with a closed cell foamgasket installed along the top surface of the bin.)7. Remove all panels from ice machine before lifting.and installing on bin. Remove both front panels, topcover, left and right side panels.Air BaffleSelf-Contained Air-cooled OnlyThe air-cooled baffle prevents condenser air fromrecirculating. To install:1. Loosen the back panel screws next to thecondenser.2. Align the keyhole slots in the air baffle with the screwholes and slide the baffle down to lock in place.AIRBAFFLE8Part Number 000007345 2/12
Section 2Installation InstructionsElectrical Service! WarningAll wiring must conform to local, state and nationalcodes.VOLTAGEThe maximum allowable voltage variation is 10% of therated voltage at ice machine start-up (when the electricalload is highest).! WarningThe ice machine must be grounded in accordancewith national and local electrical codes.All electrical work, including wire routing and grounding,must conform to local, state and national electricalcodes. The following precautions must be observed: The ice machine must be grounded. A separate fuse/circuit breaker must be provided foreach ice machine. A qualified electrician must determine proper wiresize dependent upon location, materials used andlength of run (minimum circuit ampacity can be usedto help select the wire size). The maximum allowable voltage variation is 10% ofthe rated voltage at ice machine start-up (when theelectrical load is highest). Check all green ground screws in the control box andverify they are tight before starting the ice machine.ImportantObserve correct polarity of incoming line voltage.Incorrect polarity can lead to erratic ice machineoperation.MINIMUM CIRCUIT AMPACITYThe minimum circuit ampacity is used to help select thewire size of the electrical supply. (Minimum circuitampacity is not the ice machine’s running amp load.)The wire size (or gauge) is also dependent uponlocation, materials used, length of run, etc., so it must bedetermined by a qualified electrician.ELECTRICAL REQUIREMENTSRefer to Ice Machine Model/Serial Plate for voltage/amperage specifications.GROUND FAULT CIRCUIT INTERRUPTERGround Fault Circuit Interrupter (GFCI/GFI) protection isa system that shuts down the electric circuit (opens it)when it senses an unexpected loss of power,presumably to ground. Manitowoc Ice does notrecommend the use of a GFCI/GFI circuit protection withour equipment. If code requires the use of a GFCI/GFIthen you must follow the local code. The circuit must bededicated, sized properly and there must be a panelGFCI/GFI breaker. We do not recommend GFCI/GFIoutlets as they are known for more intermittent nuisancetrips than panel breakers.MINIMUM POWER CORD SPECIFICATIONSMaximumBreaker Size15 amp20 amp30 amp40 ampMinimumWire Size14 gauge12 gauge10 gauge8 gaugeMaximum Length ofPower Cord6 feet (1.83 m)6 feet (1.83 m)6 feet (1.83 m)6 feet (1.83 m)If a power cord is used, the wire size to the receptacle isdependent upon location, materials used, length of run,etc., so it must be determined by a qualified electrician.Local, state or national requirements will supersede ourminimum requirements.FOR UNITED KINGDOM ONLYFUSE/CIRCUIT BREAKERA separate fuse/circuit breaker must be provided foreach ice machine.

Section 2Installation InstructionsWater Supply and Drain RequirementsWATER SUPPLYWATER-COOLED CONDENSER WATER PRESSURELocal water conditions may require treatment of thewater to inhibit scale formation, filter sediment, andremove chlorine odor and taste.Water pressure at the condenser cannot exceed 150psig (1034 kPa) with the standard water-regulatingvalve. Contact your distributor if your water pressure isgreater than 150 psig (1034 kPa). A special ordercondensing unit is available that allows water pressureup to 350 psig (2413 kPa)! WarningConnect to a potable water supply only.COOLING TOWER APPLICATIONS(WATER-COOLED MODELS)WATER INLET LINESFollow these guidelines to install water inlet lines: If you are installing a Manitowoc Arctic Pure waterfilter system, refer to the Installation Instructionssupplied with the filter system for ice making waterinlet connections.Do not connect the ice machine to a hot watersupply. Be sure all hot water restrictors installed forother equipment are working. (Check valves on sinkfaucets, dishwashers, etc.)If water pressure exceeds the maximumrecommended pressure of 80 psi (552 kPa), obtain awater pressure regulator from your Manitowocdistributor. Install a water shut-off valve for both the ice makingand condenser water lines. Insulate water inlet lines to prevent condensation.! CautionDo not apply heat to water valve inlet fitting. This willdamage plastic water inlet connection.DRAIN CONNECTIONSA water cooling tower installation does not requiremodification of the ice machine. The water regulatorvalve for the condenser continues to control therefrigeration discharge pressure.It is necessary to know the amount of heat rejection, andthe pressure drop through the condenser and watervalves (inlet and outlet) when using a cooling tower onan ice machine. Water entering the condenser must not exceed90 F (32 C). Water flow through the condenser must not exceed5 gallons (19 liters) per minute. Allow for a pressure drop of 7 psi (50 kPa) betweenthe condenser water inlet and the outlet of the icemachine. Water exiting the condenser must not exceed110 F (43 C).ImportantThe Commonwealth of Massachusetts requires thatall water-cooled models must be connected only to aclosed loop, cooling tower system.Follow these guidelines when installing drain lines toprevent drain water from flowing back into the icemachine and storage bin: Drain lines must have a 1.5 inch drop per 5 feet ofrun (2.5 cm per meter), and must not create traps. The floor drain must be large enough toaccommodate drainage from all drains. Run separate bin and ice machine drain lines.Insulate them to prevent condensation. Vent the bin and ice machine drain to theatmosphere. Do not vent the condenser drain onwater-cooled models.Part Number 000007345 2/1211
