    INTRODUCTION This manual is intended as a reference for the installation of a Scotsman ice maker model CMS1002. Specifications ........2 Environmental Limitations .
  • Page 2: Specifications

    CMS1002 ice machines. It interconnects the sonar bin ice level controls. CMS1002 may only be stacked onto another CMS1002. The CMS1002 will fit any 30" wide Scotsman bin without needing a bin top. Other bins will require a bin top.
  • Page 3: Environmental Limitations

    They meet or exceed the standards of UL, NSF, and CSA. Scotsman assumes no liability or responsibility of any kind for products manufactured by Scotsman that have been altered in any way, including the use of any part and/or other components not specifically approved by Scotsman.
  • Page 4: For The Installer: Machine & Bin Assembly

    6. Use bolts and straps found in the hardware package to secure the ice machine to the ice storage bin. When alignment and leveling are completed, tighten the bolts to secure the mounting straps.
  • Page 5: For The Plumber

    The drains to be installed must conform with the local plumbing codes. Install a vertical open vent on the ice machine reservoir drain. The ideal drain recptacle is a trapped and vented floor drain. The storage bin drain should be insulated.
  • Page 6: For The Electrician

    CMS1002W FOR THE ELECTRICIAN: Electrical Connections See the NAMEPLATE for current requirements to determine wire size to be used for electrical hookup. The cuber requires a solid chassis to chassis earth ground wire. See Wiring Diagram. Be certain the cuber is connected to its own electrical circuit and individually fused.
  • Page 7: Final Check List

    12. Has the Field Quality Audit form been properly filled out? Check for correct model and serial numbers from Serial nameplate, then mail the completed form to the SCOTSMAN factory. 13. Has the owner been given the name and telephone number of the authorized SCOTSMAN...
  • Page 8: Initial Start Up

    CMS1002W INITIAL START UP Ice Maker: 1. Remove front panel by pulling out to unsnap. 2. Remove two screws and the control box cover. 3. Remove the evaporator cover. 4. Remove the left side service panel. 5. Check that the ON/WASH/OFF rocker switch and the Compressor ON-OFF toggle switch are in the OFF position, on the control box.
  • Page 9 3. Hold a flat object about the size of this service manual over the ice level sensor socket. 4. The ice machine should turn off at the end of the harvest cycle. 5. Slowly lower the flat object straight down.
  • Page 10: Adjustments

    Rotating the shaft of the timer cam Clockwise will put the ice machine into the freeze or harvest cycle, as required in the cleaning instructions.
  • Page 11: Component Description

    The hot gas solenoid valve is installed in a branch of the discharge line, and when the timer switches the ice machine into the harvest cycle, the energized solenoid coil lifts the valve stem within the valve body, allowing the hot discharge gas to be diverted to the evaporators.
  • Page 12 Ice Level Control This electronic control uses sound waves to measure the distance between the bottom of the ice machine and the top of the ice in the bin. It is designed to control the machine’s ice production to maintain that distance.
  • Page 13 High Pressure Safety Control This is a manual reset control that shuts down the icemaker, should the discharge pressure ever reach 350 PSIG. ELECTRIC WATER VALVE September, 1993 Page 13 CMS1002W WATER DISTRIBUTION SYSTEM EVAPORATOR WATER PUMP RESERVOIR HIGH PRESSURE...
  • Page 14: Service Specifications

    Harvest time is assumed to be 2.25 minutes. This can be adjusted to suit local conditions. COMPONENTS gallon per minute during the harvest cycle. 8" from the base of the ice machine. 21" - 22" from the base of the ice machine. 8’ from the base of the ice machine. 220 P.S.I.G. 26-23 P.S.I.G.
  • Page 15: Cleaning

    CLEANING /////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// A Scotsman Ice System represents a sizable investment of time and money in any company’s business. In order to receive the best return for that investment, it MUST receive periodic maintenance. Maintenance and Cleaning should be scheduled at a minimum of twice per year.
  • Page 16 1 ounce of household bleach to 2 gallons of water. 3. Using clean rubber gloves and a clean cloth, wipe all interior surfaces of the ice machine and ice storage bin with the sanitizing solution. Immerse any small parts in the sanitizing solution...
  • Page 17: Service Diagnosis

    1. Too much heat load. 2. Compressor inefficient. 3. Non condensable gasses in refrigeration system. September, 1993 Page 17 CMS1002W PROBABLE CORRECTION 1. Restore power 2. Reset breaker or replace fuse, check for electrical fault. 3. Reset HPC, check fan motor for proper operation, and condenser coil for dirt.
  • Page 18 CMS1002W SERVICE DIAGNOSIS SYMPTOM Low ice production No ice falling in bin, unit frozen up Ice maker stuck in harvest cycle Ice is mal-formed Water overflows from reservoir into bin. POSSIBLE CAUSE 4. High head pressure, a result of a dirty condenser 5.
  • Page 19 SERVICE DIAGNOSIS: Ice Level Control Circuit CONDITION Ice Machine does not run, it has power to it, the high pressure control is closed, the on/off switch is set to ON. Machine runs, makes ice, switches on and off, but ice level cannot be controlled.
  • Page 20: Removal And Replacement

    CMS1002W REMOVAL AND REPLACEMENT TRANSDUCER 1. Disconnect electrical power BEFORE removing transducer. 2. Open bin door and locate the transducer socket. 3. Twist inner portion of transducer counter- clockwise and push up gently. 4. Pull transponder down until plug connection is accessible.
  • Page 21: Removal And Replacement

    4. Pull electrical cord connection from solenoid coil terminals. 4. Remove inlet water fitting from the water solenoid valve. To replace the inlet water valve assembly, reverse the removal procedures. September, 1993 Page 21 CMS1002W SOLENOID VALVE...
