Introduction This manual includes information for the installation, operation and maintenance of the SCN60 residential ice machine. The SCN60 was developed to offer fans of Scotsman’s Nugget Ice form the ability to have that ice in their homes.
Product Description: This ice machine is designed to be used indoors, in a controlled environment or outdoors within certain limits. The SCN60 is made up of two major systems: the ice making system and the ice storage system.
Cabinet Dimensions May 2011 Page 3 SCN60 Installation and Use Scotsman Ice Systems are designed and manufactured with the highest regard for safety and performance.
Location Recommendations: The machine can be built into a cabinet. It is an air cooled refrigeration system and so air flows in and out of it through the grill at the bottom front. The grill must not be blocked by any covering door or other obstruction.
Familiarization The control panel is visible when the door is opened. It has three indicator lights and two switches. The model and serial number plate is located on the bottom of the control panel box. The Bin Light and Ice Level Sensor are also visible from that angle, as is the Ice Chute.
Decorating Features: The machine ships unfinished, allowing the attachment of a decorator door panel or a metal panel from Scotsman. Door Panel The ice machine is supplied without a conventional door covering so it can be decorated to the user ’s preference.
Door Panel Attachment May 2011 Page 7 SCN60 Installation and Use Gasket Scotsman Door Panel Cover Machine Screw Use Upper Hole at the Top Use Lower Hole at the Bottom Hole Plug.
Door Swing The door swing is reversible. The door can be attached to open with hinges on the left or right using new hinge brackets shipped loose in the ice bin. Retain all screws for re-use. To change: 1. Remove hinge cover and innermost screw holding each hinge to cabinet, loosen the other.
Plumbing - Pump Model Drains There are two types of ice machine models, one that drains by gravity and one that has an internal drain pump. Drain Pump Model drain installation 1. Locate the coil of 3/8” ID plastic drain tubing secured to the back of the unit.
Plumbing: Gravity Drain Model Caution: Restrictions in the drain system to the machine will cause water to back up into the ice storage bin and melt the ice. Gravity drain tubing must be vented, have no kinks and slope to the building drain. Air gaps are typically required by local code.
Electrical and Start Up The ice machine is supplied with a power cord. Do not remove the grounding pin from the cord ’s plug. Do not use extension cords. Follow all codes. Connect the machine to its own 115 volt, 15 amp circuit. 1. If the electrical outlet for the ice maker is behind the unit, plug in the unit.
Use No special instructions are needed for use. Just take as much ice as you need, the machine will replace it. A scoop is provided, and it can be stored in the machine using the loop of tubing on the right side as a holder. The machine can be shut off anytime by just pushing and releasing the On/Off button.
Maintenance Scotsman strongly recommends regular maintenance of this ice machine. During normal operation mineral scale that is in the water supply will gradually build up on the ice making surfaces. That build up can cause excessive loading of the ice making system, which can cause premature failure.
How to remove scale from the ice making system. Cleaning this machine involves adding a solution of scale remover and water to the ice machine and continuing to add it as it makes ice. The scale remover must be diluted to the correct ratio. A squirt bottle will make adding the scale remover much easier when the unit is built in.
6. Locate blue float valve on/off lever. Move lever up about half way to shut water off. 7. Locate drain plug and pull the drain plug out to drain the reservoir and evaporator.
11. Press and HOLD both the Clean-Reset and On/Off buttons for 5 seconds. The Time to Clean light will blink on and off. 12. The auger motor alone will be operating for 10 minutes, after that the compressor will start and in about 5-8 minutes the machine will start to make ice.
SCN60 service This section contains information for the service and repair of the SCN60 ice machine. May 2011 Page 1 SCN60 Service Service Table of Contents SCN60 service .............................................. Page 1 Components: ..............
Components: • Refrigeration system, including air cooled condenser, compressor, capillary tube and evaporator. • Control system, including ice level sensor, water sensor, auger motor sensor, controller, control pad and transformer. • Auger drive system, including auger motor, gear reducer and auger.
Evaporator and Auger May 2011 Page 3 SCN60 Service Cut Away View Stationary Half of Water Seal Rotating Half of Water Seal Heat Exchange Tube Coil Auger Ice Outlet Bearing Foam Insulation Water Inlet.
Control System The control system operates the machine. The controller operates on 12 volts AC, supplied by the transformer. It uses an ultrasonic ice sensor to measure ice level.
Water System The auger is driven at about 11 RPM by the gear reducer. The gear reducer is a sealed component and does not require lubrication, as it contains a charge of grease. The auger motor drives a set of gears that all together reduce the motor speed to the 11 RPM output speed and correspondingly increasing the torque.
Storage The ice storage system is made up of a plastic lined ice storage bin, covered by an insulated top panel and an insulated swing open door with gasket.
Performance and Technical Specs Overall: • Refrigerant: 4.5 oz R-134a • Compressor: Hermetic, 700 BTUH • Condenser: Forced draft • Fan blade: 3 blade, 6 inch • Evaporator: Stainless steel tu.
Electrical Sequence Upon power being supplied, all the lights will blink once and the control system will immediately check for water in the reservoir. If there is water no further action will occur until the On/Off button is pushed. Pushing the On/Off button starts the machine.
Service Diagnosis May 2011 Page 9 SCN60 Service Problem Likely Cause Probable Solution No ice No power Plug unit into power supply Unit switched off Push and release on/off button No water, water diagnostic light is on Restore water supply, check sensor.
Service Diagnosis May 2011 Page 10 SCN60 Service Problem Likely Cause Probable Solution No ice, continued Ice level sensor failure With power on and Ice Making light on, check connector, if secure remove connector and jump the two middle pins at J9 on the controller together.
Component Diagnostics Membrane Switch Unplug and check connector pins (left side is pin 1), read about 10 ohms when activating the button, and OL when not pressing the button: Pin 2-3 On/Off Switch; 4-3 Clean Reset Switch Compressor Check temperature of compressor, if very hot, add access valves to refrigeration system and check system pressures.
Ice Capacity The rate of ice making is relatively fixed, it depends upon the heat load and the ambient temperature the machine is operating in. As either increase the amount of ice made will decrease. The machine will work to keep the ice bin full. A full bin of ice is when the ice level is even with the top of the front of the bin.
Removal and Replacement Component Access The machine is designed to be cleaned while built in. See the Maintenance section for more information. Most components require the machine to be removed from .
