Section 2 Installation InstructionsPart Number 000006520 11/11 7Electrical ServiceVOLTAGEThe maximum allowable voltage variation is ±10% of therated voltage at ice machine start-up (when the electricalload is highest).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.FUSE/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).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 SPECIFICATIONSIf 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.! WarningAll wiring must conform to local, state and nationalcodes.! WarningThe ice machine must be grounded in accordancewith national and local electrical codes.ImportantObserve correct polarity of incoming line voltage.Incorrect polarity can lead to erratic ice machineoperation.MaximumBreaker SizeMinimumWire SizeMaximum Length ofPower Cord15 amp 14 gauge 6 feet (1.83 m)20 amp 12 gauge 6 feet (1.83 m)30 amp 10 gauge 6 feet (1.83 m)40 amp 8 gauge 6 feet (1.83 m)FOR UNITED KINGDOM ONLYAs 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 symbol or 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.• The wire colored brown must be connected to the terminal which ismarked with the letter L or colored red.
