Installation and User's Manual for Flake and Nugget Ice Machine Models FME504, FME804, NME454, NME654
NME454, 654 & FME504, 804 INTRODUCTION To the owner or user: This manual is intended to provide you with the information needed to install, start up, clean, and maintain this ice system. This is a modular ice system that fits a variety of Scotsman ice storage bins.
NME454, 654 & FME504, 804 FOR THE INSTALLER These machines fit the following Scotsman products, check sales literature for other possible combinations: · SB480 and extensions (with bin top KBT18) · HTB555 or BH550 using bin top KBT14 or KBT20 · BH801 using bin top KBT28 · BH900 using bin top KBT24 NME Dispenser Applications The NME models can be placed on and used with certain ice and ice-beverage dispensers.
NME454, 654 & FME504, 804 SAMPLE BIN AND MACHINE COMBINATIONS FME804 ON BH550* The Nameplate is located on the back of the machine. A Serial Number Plate is located inside the cabinet, behind the front panel.
NME454, 654 & FME504, 804 FOR THE INSTALLER Location: Install the machine be installed in a location where it has enough space around it to be accessible for service. A minimum of 6" must be allowed at the back and sides for air circulation on air cooled models. Try to avoid hot, dirty and crowded locations. Be sure that the location for the machine is within the environmental limitations. Storage Bin: Tip the storage bin on its back, using parts of the carton to protect the exterior finish.
NME454, 654 & FME504, 804 FOR THE INSTALLER: Location ALLOW AIR SPACE ON BOTH SIDES TWO UNITS ON ONE BIN ALLOW ROOM FOR AIR CIRCULATION AND SERVICE ACCESS Airflow Notice: Air flow is in the sides and out the back.
NME454, 654 & FME504, 804 FOR THE PLUMBER CONFORM TO ALL APPLICABLE CODES Water Inlet Drains Air Cooled Models: Use 3 8" O.D. copper tubing to connect cold potable water to the 3 8" male flare fitting at the back of the cabinet. Install a hand valve near the machine to control the water supply. Water Treatment: In most areas, a water filter of some type will be useful.
NME454, 654 & FME504, 804 FOR THE ELECTRICIAN CONFORM TO ALL APPLICABLE CODES Connect the electrical power to the machine to the wires in the junction box at the rear of the machine. Check the nameplate (located on the back panel) for the voltage requirements, and for the minimum circuit ampacity. The machine requires a solid chassis to earth ground wire. The ice machine should be connected to its own electrical circuit so it would be individually fused.
NME454, 654 & FME504, 804 INITIAL START UP Pre-Start Inspection 1. Remove the front and side service panels. are rubbing each other. Check that the fan blade turns freely (air cooled). 2. Check that any shipping blocks have been removed. 4. Check that the unit is installed correctly according to the final check list (page 8). 3. Inspect the interior of the machine for loose screws or wires. Check that no refrigerant lines Start Up · The air cooled discharge pressure will depend 1.
NME454, 654 & FME504, 804 CLEANING & SANITIZING 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; adjusting it as needed; and by replacing worn parts before they can cause failure.
NME454, 654 & FME504, 804 SENSOR MAINTENANCE 1. The bin control is a device that senses light, therefore it must be kept clean so it 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. 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.
NME454, 654 & FME504, 804 AIR COOLED MAINTENANCE Hazardous Moving Parts. Moving fan blade can cause personal injury. Disconnect electrical power before beginning. Clean the air cooled condenser. The air flow on this model is from front to back, so the inside of the machine will have to be available to clean the air cooled condenser. Use a vacuum cleaner or coil cleaner if needed. Do NOT use a wire brush. A. Disconnect electrical power, and remove the filter. The filter may be cleaned or replaced. B.
NME454, 654 & FME504, 804 BEARING MAINTENANCE The bearing in the breaker should also be checked at least two times per year. A. Check the bearing by: · unscrewing the auger stud Auger Stud · removing the ice chute cover Chute Cover Cap Screw · unscrewing the ice sweep Ice Sweep Inspect the bearing. There should be plenty of grease in sight. If grease is needed the bearing and breaker should be removed to check the action of the bearing. It should rotate smoothly.
NME454, 654 & FME504, 804 AUGER MAINTENANCE 4. Remove 4 allen screws holding breaker to In some areas, the water supply to the ice maker evaporator. will contain a high concentration of minerals, and that will result in an evaporator and auger 5. Pull up to remove auger. becoming coated with these minerals, requiring a After the auger has been removed, allow the auger more frequent removal than twice per year.
NME454, 654 & FME504, 804 REMOVAL AND REPLACEMENT: Bin Controls BIN CONTROLS (Ice Level Sensors) 1. Disconnect electrical power. 2. Remove front panel. 3. Remove control box cover. 4. Locate ice chute, at the base of the chute, in front of and behind it are two plastic bin control mounts. 5. Slide each bin control to the left, and in the control box, disconnect the electrical leads connecting the bin control to the circuit board. 6.
