To The Installer: A professional installation of any product is critical to the long term satisfaction of the user. The AFE325 is designed to be installed indoors, near a drain. Determine the location from the anticipated use and any options planned for. This air cooled machine blows air out the back and left sides of the cabinet. Do not install th[...]

For The Plumber Drains: The ice maker requires a gravity drain for the reservoir overflow and bin drain. T he pit c h on the drain tubes must be at least 1/ 4 inch f all per foot of horizontal run. On long horizont al runs, a vent at the back of t he cabinet will improve draining, and is recommended. Water supply: Connect cold, potable water t o t [...]

For The Electrician Electrical connections: Follow All Local, State & National Codes Check the nameplate for voltage and current requirements. An electrical cord is not supplied. Connect the AFE325 to a separate electrical circuit. Wiring to the machine must conform to all codes. A licensed electrician may be required in some situations. The el[...]

Final Check List & Initial Start Up 1. Is the machine located indoors where the temperature limitations are not exceeded? 2. Is there at least 6" clearance on the left side and the back of the cabinet for adequate air flow? 3. Is the water supply adequate, and has a shut off valve been installed? 4. Is the cabinet level? 5. Have all of the[...]

User Operation The AFE325 is an automatic ice flaked machine. All it requires is cool air, clean water, a drain, and an adequate supply of electrical power. The user must regularly sanitize and clean the machine. Component Location & Function Evaporator. This is a vertical cylinder full of water and refrigerated. Also in the cylinder is a slowl[...]

Component Location: Control Box Auger Delay Pressure Control: This pressure switch, connected to the low side of the refrigeration system, controls the auger drive motor. On-Off switch: This toggle switch shuts off the machine. It is not a complete disconnect. Bin Thermostat: This thermostat turns the machine on and off in response to changes in te[...]

Refrigeration System Operation The AFE325 uses a forced draft air cooled condenser, capillary tube and hermetic compressor. The system uses R-134a as a refrigerant. High pressure, high temperature refrigerant is forced thru the condenser where it looses enough heat to condense. The high pressure liquid refrigerant then passes thru the capillary tub[...]

Water System Operation: The water system consists of a float valve and reservoir. The water level in the reservoir tank is the same level as that inside the evaporator. Building water supply flows to the float valve and the float valve opens to add water to the reservoir as water flows out to the evaporator. Inside the evaporator there is a water s[...]

Mechanical Operation ELECTRICAL SEQUENCE There are two circuits in the AFE325: one is a series circuit with several switches connected in series to the compressor. The other is a parallel branch of the series circuit, controlling the gear drive motor. • The series circuit begins at the terminal strip in the control box. From there, the line side [...]

Maintenance and Cleaning In some areas, the water supply to the ice maker will contain a high concentration of minerals, and that will result in an evaporator and auger becoming coated with these minerals, requiring a more frequent removal than twice per year. If in doubt about the condition of the evaporator and auger, the auger can be removed so [...]

Maintenance: Air Cooled Condenser, Bearings 1. Disconnect electrical power. 2. Remove front louvered panel 3. Wipe the lint off the front of the condenser. If needed, clean the interior of the condenser. 4. Use pressurized air to blow the lint from the inside of the condenser. A vacuum cleaner hose should pick up most of the dust. Check for interio[...]

Maintenance: Component Inspection Auger. The auger is made of stainless steel. It has a polished surface that may be very shinny or dull. Allow the auger to dry, if mineral scale is found on the auger’s surface, clean off the auger with ice machine cleaner and a scrubbing pad. Remove the water seal and clean off the shoulder of the auger. Bearing[...]

Service Diagnosis Problem Possible Cause Probable Correction No ice, nothing is operating. Unit has no power. Restore power. If breaker or fuse tripped, check for overloaded circuit or short circuit. Master switch off Switch unit on. Determine why switch was off. No water (water safety switch open) Restore water supply. Check filters or strainer. S[...]

Service Diagnosis PROBLEM POSSIBLE CAUSE PROBABLE CORRECTION Unusual noise Mineral scale in evaporator Clean water system with ice machine cleaner. Auger coupling dry Grease coupling Auger coupling worn Replace coupling and adapter stand. Bearings worn Replace bearings and water seal. Gearmotor loose on frame Tighten bolts, check grommets Low water[...]

Removal and Replacement Water System The water system consists of the reservoir and inlet water valve. Reservoir. 1. Shut off the water supply. 2. Remove the top panel. 3. Remove the left side panel. 4. Drain the water reservoir and evaporator. 5. Disconnect inlet and outlet tubes from the reservoir. 6. Remove screws holding reservoir to its mounti[...]

Water Seal & Bottom Bearing Replacement: 1. Remove old rotating half from the auger. Clean the mounting area. 2. Place a bead of food grade sealant (such as Scotsman part number 19-0529-01) onto the shoulder of the auger where the rotating half of the water seal will be installed. 3. Wash the new seal in water. While wet, slip it onto the botto[...]

Refrigeration System This ice machine uses R-134a as the refrigerant. This refrigerant has no chlorine, and therefore requires polyolester type refrigerant oil. This oil requires specific service procedures. Service Recommendations: This ice machine has a sealed refrigeration system. It must not be tapped into unless absolutely necessary. If access[...]

Gear Reducer Removal 1. Disconnect electrical power. 2. Shut off the water supply. 3. Remove the top, front and side panel. 4. Remove the control box cover. 5. Remove the centrifugal switch cover on the top of the auger drive motor. 6. Disconnect the electrical wires from the centrifugal switch. 7. Drain the evaporator and reservoir. 8. Disconnect [...]

Gear Reducer Rebuild 1. After the gear reducer has been removed, the internal components may be inspected and/or replaced. Remove all bolts holding the two case halves together. 2. T ap against the roll pins at each end of the gear cases to split them. 3. Pry the case halves apart. 4. Check the internal condition of the gear reducer. If rusty or wa[...]
