F. liquid line temperature (assume a 0 F. evaporator temperature). Storage Bin: Scotsman’s B90 will be the presumed bin of choice. If using the bin extension BX87, install heavy duty leg kit KLP4 and place the bin into position. Remove the paper tape from the bin edge gasket, and install the bin extension onto the B90. -
Page 4: For The Electrician
FOR THE ELECTRICIAN CONFORM TO ALL APPLICABLE CODES Electrical Connections: Locate the nameplate for the current requirements, and then determine the wire size and type per the National Electric Code. The machine requires a solid chassis to earth ground wire. Refer to the wiring diagram. -
Page 5: For The Plumber
FOR THE PLUMBER CONFORM TO ALL APPLICABLE CODES Water Supply: The recommended water supply line is 3/8" O.D. copper tubing, with a minimum operation pressure of 20 PSIG, and a maximum of 80 PSIG. Connect to cold water using the male flare connection at the back of the machine. -
Page 6: For The Installer: Final Check List
9. Has the bin and cabinet been wiped clean or sanitized? 10. Has the warranty registration card been properly filled out and mailed to Scotsman? 11. Has the owner been given the service manual and been instructed on how to maintain the ice maker? 13. -
Page 7: Initial Start-Up
INITIAL START UP 1. Remove the top and front panels. 2. Open the water valve, and observe that the two float reservoirs fill up with water and shut off. 3. Switch on the electrical power. 4. Open the hand valves (in the liquid lines). 5. -
Page 8: Component Identification
COMPONENT IDENTIFICATION Liquid line valve(s) These valves operate to turn the ice making process on and off. When the ice level drops in the ice chute, the ice level sensor will cause the circuit board to close the liquid line relay, which energizes the liquid line valve for that side of the system. -
Page 9: Component Description: Evaporator
COMPONENT DESCRIPTION: Evaporator Evaporator: A refrigerated vertical tube filled water and containing a water seal and auger. Auger: A solid stainless steel double spiral auger, it pushes the ice crystals up to the top of the evaporator. Water Seal: A two part “face” seal, the top half rotating with the auger, the bottom half stationary, the sealing action being where the two seal “faces”... -
Page 10: Control Box: Components
CONTROL BOX: Components Circuit Board: Controlling the ice machine using input from ice and water sensors. The board switches loads on and off through relays. The relays are for the gear motor (with a built in time delay to clear the evaporator of ice when the unit turns off) and for the liquid line valve. -
Page 11: Electrical Sequence
The liquid line valve will not re-open until 2 minutes or more have passed after the last shut down. If the path between the ice level sensors remains clear for more than 10 seconds the ice machine will restart. Control Board Protection Devices ·... -
Page 12: Operation
Double System RL OPERATION Water Water enters the machine through the 3/8" male flare at the rear of the cabinet, goes to the water reservoir which it enters through the float valve. The water then goes out the bottom of the reservoir tank to the bottom of the evaporator. -
Page 13: Operation: Refrigeration
OPERATION: Refrigeration The remote high side supplies high pressure liquid refrigerant to the liquid line connection on the ice machine. After the sight glass, there are two separate liquid lines, each leading to a liquid line valve. When the individual ice level sensor causes the circuit board to energize the liquid line valve, the valve opens, allowing the liquid refrigerant to enter that expansion valve. -
Page 14: Cleaning And Sanitation
CLEANING and SANITATION 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. It is the USER’S RESPONSIBILITY to see that the unit is properly maintained. It is always preferable, and less costly in the long run, to avoid possible down time by keeping it clean;... -
Page 15: Sensor Maintenance
CLEAN THE ICE LEVEL CONTROL SENSORS 2. The ice machine senses water level by a probe located in the water reservoir. At least twice a year, the probe should be removed from the reservoir, and the tip wiped clean of mineral build-up. -
Page 16: Bearing Maintenance
If the bearing only needs grease, inject grease into the bearing using Scotsman grease needle pn Ice Sweep 02-3559-01 and Scotsman bearing grease cartridge, pn A36808-001. Be sure to inject grease evenly and thoroughly. -
Page 17: Auger Maintenance
AUGER MAINTENANCE In some installations the water supply to the ice maker will be so concentrated with dissolved minerals, (such as calcium carbonate) that as ice is made, the evaporator and auger become coated with those minerals, requiring a more frequent cleaning than twice per year. -
Page 18: Service Diagnosis
Auger can’t turn. Circuit board has not yet shut unit down. Liquid line valve not opening, check coil, check board relay. No refrigerant to ice machine, check main system. Circuit board has shut ice machine down due to high auger motor amp draw. - Page 19 Check gear motor for water infiltration. Replace float valve or seat Clean out bin drain. Drains must be separate. Adjust or replace Clean with Scotsman Ice Machine Cleaner Oil or replace motor...

If it is on, the ice sensors may be blocked. Remove them and check for mineral scale. Scotsman's test box can also be used to determine if the ice sensors or board are defective. -
Page 21: Removal And Replacement
REMOVAL AND REPLACEMENT WATER RESERVOIR 1. Shut off the water supply to the ice maker. 2. Remove front panel and reservoir cover. 3. To remove float only, disconnect water inlet tube, push in the tab behind the reservoir and pull valve assembly out of the reservoir tank. -
Page 22: Removal And Replacement: Bearing And Breaker
7. Reverse to reassemble: specific tools and materials are required to install properly. a. Add food grade grease such as Scotsman part number 19-0569-01 to the seal area before installing on the auger. b. Check the seal to shaft areas for cuts, or rough spots: none are permitted. - Page 23 Scrub the auger with ice machine cleaner and hot water. Ice machine cleaner is an acid. Handle it with extreme care, keep out of the reach of children. 2. The water seal area. Because the auger has been removed, the water seal will have to be replaced.
- Page 24 4. Place a small bead of food grade silastic sealant (such as 732 RTV or Scotsman part number 19-0529-01) on the area of the auger where the water seal is to be mounted.

Page 25: Removal And Replacement: Evaporator
REMOVAL AND REPLACEMENT: Evaporator To Replace the Evaporator: (Assuming all the steps for removal of the thrust bearing, breaker, auger, and water seal have been performed.) 1. Shut the hand valves in the liquid and suction lines to the evaporator being serviced; then discharge the refrigerant. -
Page 26: Removal And Replacement: Gearmotor
REMOVAL AND REPLACEMENT: Gearmotor To Remove and Repair the Gearmotor Assembly: (Assuming that the procedures through removal of the water seal have been performed.) 1. Remove the electrical wires from the gear drive motor. 2. Unscrew the 4 cap screws holding the gearmotor to the gearmotor plate.
