FOR THE INSTALLER
Installation Limitations:
The machine and bin are designed to be installed indoors, in a controlled environment: Min Air Temperature Water Temperature Water Pressure (PSI) Voltage 500F 1000F 1000F 80 253 Max
Location
Install the machine in a location where it has enough space around it to be accessible for service, usually a minimum of 6 inches. Be sure that the location for the machine is within the limitations.

Storage Bin
(Compared to the nameplate) Operating the machine outside of the limitations is misuse and can void the warranty. Scotsman Ice Systems are designed and manufactured with the highest regard for safety and performance. [. . . ] connecting power to the contactor coil

The bin full light remains off and the machine stays on until ice builds up in the bin and blocks the path between the sensors for 6 seconds or longer. When that occurs the bin full light glows and the machine shuts down.

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 them goes out the bottom of the reservoir tank to the bottom of the evaporator. Reservoir overflow or evaporator condensation is routed to the drain.

OPERATION: Refrigeration
Beginning at the compressor, the refrigerant is compressed into a high temperature gas. At the remote condenser the gas is cooled by air and it then condenses into a liquid. This high pressure liquid then goes through the liquid line to the head pressure control valve, into the receiver, through the liquid line valve and then through the expansion valve. The thermostatic expansion valve meters liquid refrigerant into the evaporator, the volume of liquid refrigerant depending upon the temperature of the evaporator; warmer evaporators get more refrigerant and colder evaporators get less. Refrigeration Schematic
NME954R & WRF736SDAB
At the evaporator, the refrigerant enters an area of relatively low pressure, where it can easily "boil off" or evaporate. As it evaporates, it absorbs heat from the evaporator and whatever is in contact with it (such as the water inside it). Sanitize the bin interior by washing the interior of the bin with the balance of the sanitizer solution. Slowly pour the cleaning solution into the water reservoir until it is full. As the ice maker begins to use water from the reservoir, continue to add more cleaning solution to maintain a full reservoir. After all of the cleaning solution has been added to the reservoir, and the reservoir is nearly empty, switch the master switch to OFF.

Sensor Maintenance
1. The bin control uses devices that sense light, therefore they must be kept clean enough so that they can "see". At least twice a year, remove the bin control sensors from the base of the ice chute, and wipe the inside clean, as illustrated.
Ice Chute
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.
Ice Level Sensors Slide Left To Remove
Clean the Probe's Tip with ice machine cleaner and a clean, soft cloth.
3. Check and tighten all bolts and screws.

Bearing Maintenance
The top bearing in the breaker should be checked at least two times per year. Check the breaker bearing by: ·removing the ice chute cover

Inspect the bearing. If grease is needed the bearing and breaker should be removed to check the action of the bearing. [. . . ] Complete the reassembly by reversing the disassembly for the breaker & thrust bearing assembly.

REMOVAL AND REPLACEMENT: Gear Motor Assembly
To Check the Motor:
NME954R & WRF736SDAB
check the gears and bearings. If there is evidence of water in the oil (rusty bearings and gears; the oil having a creamy white appearance; oil level too high) carefully inspect the bearings and gears. Note: The gears and bearings are available only as pressed together sets. D) After replacing parts as required, (if any) reassemble the gearcase. [. . . ]
