Installation InstructionsIce Machine Heat of RejectionSeriesIce S1600S1800S3300 ST3000Heat of RejectionAir use the heat of rejection varies during the ice making cycle,the figure shown is an average.Ice 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.6Section 2Removing Drain Plug and Leveling the IceStorage Bin1. 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. Remove the back panel screws next to thecondenser.2. Align the mounting holes in the air baffle with thescrew holes and reinstall the screws.AIRBAFFLEPart Number 000006520 Rev 02 2/18
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. Circuit breakers must be H.A.C.R.rated (does not apply in Canada).Part Number 000006520 Rev 02 2/18As the colors of the wires in the mains lead of the appliance may notcorrespond with the colored markings identifying the terminals in your plug,proceed as follows: The wire which is colored green and yellow must be connected to theterminal in the plug which is marked with the letter E or by the earthground symbolor colored green or green and yellow. The wire colored blue must be connected to the terminal which is markedwith the letter N or colored black.

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 (10.34 bar) with the standard water-regulatingvalve. Contact your distributor if your water pressure isgreater than 150 psig (10.34 bar). A special ordercondensing unit is available that allows water pressureup to 350 psig (24.13 bar)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.COOLING TOWER APPLICATIONS(WATER-COOLED MODELS)A 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 (32.2 C). Install a water shut-off valve for both the ice makingand condenser water lines. Water flow through the condenser must not exceed5 gallons (19 liters) per minute. Insulate water inlet lines to prevent condensation. Allow for a pressure drop of 7 psi (0.5 bar) betweenthe condenser water inlet and the outlet of the icemachine. Water exiting the condenser must not exceed110 F (43.3 C).! CautionDo not apply heat to water valve inlet fitting. This willdamage plastic water inlet connection.DRAIN CONNECTIONSFollow 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. S3300/ST3000 require a base drain connection (3/4"FPT).Part Number 000006520 Rev 02 2/18ImportantThe Commonwealth of Massachusetts requires thatall water-cooled models must be connected only to aclosed loop, cooling tower system.9

The straight end will connectto the remote condenser.Remote condenser installations consist of vertical andhorizontal line sets between the ice machine and thecondenser. When combined, they must fit withinapproved specifications. The following guidelines,drawings and calculation methods must be followed toverify a proper remote condenser installation.! CautionThe 60 month compressor warranty (including the36 month labor replacement warranty) will not applyif the remote ice machine is not installed accordingto specifications.This warranty also will not apply if the refrigerationsystem is modified with a condenser, heat reclaimdevice, or other parts or assemblies notmanufactured by Manitowoc Ice unless specificallyapproved in writing by Manitowoc Ice.3Follow these guidelines when routing the refrigerantlines. This will help ensure proper performance andservice accessibility.1. Optional - Make the service loop in the line sets (asshown below). This permits easy access to the icemachine for cleaning and service. Do not use hardrigid copper at this location.2. Required - Do not form traps in the refrigeration lines(except the service loop). Refrigerant oil must befree to drain toward the ice machine or thecondenser. Route excess tubing in a supporteddownward horizontal spiral (as shown below). Donot coil tubing vertically.3. Required - Keep outdoor refrigerant line runs asshort as possible.DOWNWARDHORIZONTALSPIRAL22311Routing Line Sets12Part Number 000006520 Rev 02 2/18
Section 2Installation InstructionsCALCULATING REMOTE CONDENSERINSTALLATION DISTANCESMake the following calculations to make sure the line setlayout is within specifications.Line Set Length1. Insert the measured rise into the formula below.Multiply by 1.7 to get the calculated rise.(Example: A condenser located 10 feet above theice machine has a calculated rise of 17 feet.)The maximum length is 100' (30.5 m).The ice machine compressor must have the proper oilreturn. The receiver is designed to hold a chargesufficient to operate the ice machine in ambienttemperatures between -20 F (-29 C) and 120 F (49 C),with line set lengths of up to 100' (30.5 m).2. Insert the measured drop into the formula below.Multiply by 6.6 to get the calculated drop.(Example. A condenser located 10 feet below theice machine has a calculated drop of 66 feet.)Line Set Rise/Drop3. Insert the measured horizontal distance into thefor
