SCCG50 & SCCP50Service ManualSpecificationsThis ice machine is designed to be used indoors,in a controlled environment. It can be used in awide variety of environmental conditions, but thereare limits. Use outside of the listed limitations ismisuse and will void the warranty.Air temperature limits:The ice machine will operate adequately within thelimits, but functions best in temperatures between70 and 80 degrees F. Minimum – 50 degrees F. (10 C) Maximum – 100 degrees F. (38 C)Options:Door Panel kits: Finished door panels are availablefrom Scotsman for attachment to the machine,or a custom panel can be made.Kit NumberKDFWKDFWSKDFBKDFBSKDFSPanel FinishWhiteWhiteBlackBlackStainless SteelKickplate Extension: In some situations the leglevelers will be extended enough to become visible.A kit to extend the kickplate over the legs is KKPF.Water temperature limits: Minimum – 40 degrees F. (4.5 C) Maximum – 100 degrees F. (38 C)Cabinet Stability: In some free standinginstallations it may be prudent to add a bracket thatsecures the back of the cabinet to a wall. That kitnumber is KATB.Water pressure limits: Minimum – 20 psi (1.4 bar) Maximum – 80 psi (5.5 bar)Drain Conversion:Because the ice machine is making a food product,the water supply to the ice machine must bepotable, or fit for human consumption.Electrical 115 volt, 60 Hz. Plug into dedicated 15 ampcircuit. Power consumption: 275 - 400 Watts. Variesduring Freeze and Harvest cycles.Voltage limits: Minimum - 104 volts Maximum – 126 voltsA gravity drain model can be converted to a drainpump model by installing a drain pump kit. Thedrain pump kit consists of a drain pump, wiringharness and associated tubing. The kit number isA39462-021.Warranty InformationWarranty information is supplied separately fromthis manual. Refer to it for coverage. In general,the warranty covers defects in materials orworkmanship and does not cover corrections ofinstallation errors or maintenance.Models: All are air cooled (A series began 8/09): Handle FinishWhiteStainless SteelBlackStainless SteelStainless SteelSCCP50MA-1WU – Pump model, white cabinet - discontinued 2013SCCG50MA-1WU – Gravity drain model, white cabinet - discontinued 2013SCCP50MA-1BU – Pump model, black cabinet - discontinued 2013SCCG50MA-1BU – Gravity drain model, black cabinet - discontinued 2013SCCP50MA-1SU – Pump model, stainless cabinet, unfinished doorSCCG50MA-1SU – Gravity drain model, stainless cabinet, unfinished doorSCCP50MA-1SS – Pump model, stainless cabinet and doorSCCG50MA-1SS – Gravity drain model, stainless cabinet and doorNovember 2014Page 2

SCCG50 & SCCP50Service ManualAir flowThe machine takes in room temperature air at thelower right front and forces warm air out the lowerleft front. Restricting the airflow will adversely affectthe ability of the ice machine to make ice.Control PanelIce MakingAreaWarm Air OutAir IntakeScotsman Ice Systems are designed andmanufactured with the highest regard for safetyand performance. They meet or exceed thestandards of agencies like U.L.Scotsman assumes no liability or responsibility ofany kind for products manufactured by Scotsmanthat have been altered in any way, including theuse of any parts and/or other components notspecifically approved by Scotsman.Scotsman reserves the right to make designchanges and/or improvements at any time.Specifications and designs are subject to changewithout notice.June 2008Page 4

SCCG50 & SCCP50Service ManualWater QualityAll water, including potable water supplied bymunicipalities, contains some impurities orminerals. Water absorbs impurities from the air asrain and/or as it flows through the ground. Some ofthe impurities are solid particles, these are knownas suspended solids, and a fine particle filter willremove them. Other impurities are chemicallybonded to the water molecules, and cannot befiltered out, these are called dissolved solids.Ice made by this machine will have a lowermineral content than the water it was made from.This is due to the method of making ice. Purerwater will freeze first in the ice making molds.The reason for this is that anything dissolved inwater lowers the water’s freezing temperature.This concentrates most of the impurities in theice machine water reservoir where they mayform hard deposits known as scale. The machinedilutes the concentration of minerals by over-fillingthe reservoir during the harvest cycle (with theexcess water flowing down the drain). s. Between2 and 4 pints of water flow into the unit each cycle.Between 1 and 3.5 pints of that rinses the reservoirand goes down the drain.Some impurities will inevitably remain, and willstick to the parts in the machine, and will causemalformed ice cubes. Eventually, built up mineralscale can shorten machine life.To keep the machine operating properly, theseimpurities or minerals will have to be regularlydissolved by an acid cleaning, using Scotsman IceMachine Scale Remover. Directions for this may befound in the section under cleaning.Filters and TreatmentIn general, it is always a good idea to filter thewater. A water filter, if it is of the proper type, canremove taste and odors as well as particles. Somemethods of water treatment for dissolved solidsinclude reverse osmosis, and polyphosphatefeeders.RO WaterThis machine can be supplied with ReverseOsmosis water, but the water conductivity mustbe no less than 10 microSiemens/cm. A reverseosmosis system should include post treatment tosatisfy the R.O. water’s potential aggressiveness.Deionized water is not recommended.Because water softeners exchange one mineralfor another, softened water may not improve waterconditions when used with ice machines. Wherewater is very hard, softened water could result inwhite, mushy cubes that stick together.If in doubt about the water, contact a local point ofuse water specialist for recommendations on watertreatment.Installation OverviewThe ice machine must: be connected to cold, potable waterbe connected to a drainbe connected to the proper power supplybe able circulate air through the vents at thefront.Note: Do not build in so that the door is recessed.June 2008Page 5

SCCG50 & SCCP50Service ManualDoor CoveringDoor PanelCustom PanelThe ice machine is supplied without a conventionaldoor covering so it can be decorated to the user’spreference. Scotsman offers several coveringsincluding white, black and stainless steel. Inaddition, a custom built panel can be placed ontothe door.A custom panel of wood or other material notexceeding 15 lb can be attached to the door.Attachment is from the ice side of the door. Holesare provided in the door for this purpose.Door Panel AttachmentSee instructions in information packet to create andattach a custom panel:To attach a Scotsman supplied panel:Note: If door swing is to be changed, it must bedone before panel is attached.The panel will be held on by 6 sheet metal screwsand 2 machine screws.1. Remove the gasket and retain for later use.2. If the door panel is stainless steel, remove anyplastic covering the stainless steel panel.3. Place the panel onto the outside of the door,and secure it to the door using two machinescrews, located at the left center and right center.4. Fasten the panel to the door using the 6 sheetmetal screws. In the hinge area, use the outermostscrew holes.5. Place the covers over the hinge areas, andsecure each cover to the door using a sheet metalscrew.6. Insert hole plug over screw installed in step 5.7. Return the gasket to its original position.June 2008Page 6
