Introduction: This ice machine is the result of Scotsman ’s decades of experience as an industry leader in the design and manufacture of both commercial and residential ice machines. This manual includes the information needed to install, start up, maintain and service the ice machine.
Specifications This ice machine is designed to be used in a controlled environment. It can be used in a wide variety of environmental conditions and under limited conditions (see user manual), outdoors, but there are limits. Use outside of the listed limitations is misuse and will void the warranty.

Air flow The machine takes in room temperature air at the lower right front and forces warm air out the lower left front. Restricting the airflow will adversely affect the ability of the ice machine to make ice. Scotsman Ice Systems are designed and manufactured with the highest regard for safety and performance.
Water Quality All water, including potable water supplied by municipalities, contains some impurities or minerals. Water absorbs impurities from the air as rain and/or as it flows through the ground. Some of the impurities are solid particles, these are known as suspended solids, and a fine particle filter will remove them.
Door swing change The door can be attached to open with hinges on the left or right. Retain all screws for re-use. To change: 1. Remove top hinge pin from hinge. 2. Tilt top of door away from cabinet and lift door off bottom hinge. 3. Remove two screws and top hinge.
Installation Notes Sealing to floor: In some cases the base of the ice machine must be sealed to the floor to meet local code. Food grade silastic sealant such as Scotsman part number 19-0529-01 is recommended. Place the machine in the intended location.
Installation: Water & Drain The recommended water supply tubing is ¼ inch OD copper. Stainless steel flex or reinforced PVC tube may also be used. Install an easily accessible shut-off valve between the supply and the unit. This shut-off valve should not be installed behind the unit.
Gravity Drain 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 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.
Cube Size Adjustment The cube size can be adjusted by changing the amount of freeze cycle time. This is done by a button press sequence. Note: There is only one correct cube size.
Harvest Time Adjustment The harvest time can be adjusted so that all the ice harvests during the cycle, plus a few seconds extra. This is done by a button press sequence. Note: Do not set harvest time shorter than the actual time it takes to release all the cubes.
Control Settings Automatic water purge enable / disable The control is set at the factory to automatically select the proper amount of water purge. If desired, that can be disabled, and a typical purge amount used. To disable Automatic purge selection: 1.
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.
How to clean the condenser and winterize. Condenser cleaning The condenser is like the radiator on a car, it has fins and tubes that can become clogged with dirt and lint. To clean: 1. Remove the kickplate and front service panel. 2. Locate the condenser surface.
How to remove scale from the ice making system. 1. Scoop out all of the ice, either discard it or save it in an ice chest or cooler. 2. Press and HOLD the On/off button in for 3 seconds until the Green light goes out. 3. Press and HOLD the both the Clean-Reset and On/Off buttons for 5 seconds.
System Information Overall: • Refrigerant: 8 oz R-134a • Compressor: Hermetic, 1300 BTUH, • Condenser: Forced draft • Fan blade: 5 blade, 7 inch • Evaporator: Inverted, 24 cube cells.
Water System The controller uses a Water Sensor to check for the presence of water in the reservoir and to measure the conductivity of the water. The water sensor consists of two stainless steel probes located in a holder next to the water pump. The probes sense the conductivity of the water.

Controller The controller is located at the front of the unit, under the top panel. It is powered by a 12 volt transformer. It has 5 indicator lights: • Compressor - Light is ON if compressor is pow.
Performance Information Ice per cycle: 1 lb Water drained / cycle: Varies by harvest cycle length and purge setting. Typical amounts are @ 70/50 = 52 oz.

Removal and Repair Bin Thermostat 1. Disconnect electrical power. 2. Remove service panel. 3. Remove back panel. Note: If unit is built in it must be pulled out to change the bin thermostat. 4. Pull cap tube out from the back of the ice storage bin and cap tube holder.
Removal and Repair Evaporator Thermistor Note: If unit is built in it must be pulled out to change the evaporator thermistor . 1. Shut machine off. If unit was making ice, manually harvest the ice. 2. Disconnect electrical power. 3. Remove top panel. 4.
Removal and Repair - Cabinet Removal Certain components require the removal of the cabinet for repair access. 1. If the machine is in a freeze mode, perform a manual harvest. 2. Remove all ice. 3. Drain reservoir. 4. Remove service panel and kick plate.
18. Remove two screws holding freezing compartment brace to cabinet, lift brace up. 19. Lift evaporator platen up and tilt back enough for bin assembly to clear the base. 20. Remove air baffle. 21. Unplug 7 wire harness connector (at back of bin). 22.
Refrigeration Service This ice machine use R-134a type refrigerant. There are specific rules for handling that refrigerant. To check for system pressures, add a field supplied clamp-on type service valve as a temporary means of system access.
