User manual SCOTSMAN FM2400RH

[. . . ] FM2400RH TO THE OWNER OR USER: The service manual you are reading is intended to provide you, and the maintenance or service technician, with the information needed to install, start up, clean, maintain and service this ice system. The FM2400RH (remote high side) is the freezer portion of a commercial ice machine. It is designed to be connected to the condensing section of a refrigeration system, specifically a supermarket R-502 system. It consists of two evaporators, two gearmotors, two liquid line valves, two control boxes, two thermostatic expansion valves, and an EPR valve. For the Installer . [. . . ] Remove 3 hex studs holding ice chute cover to ice chute, and remove cover. Loosen band clamp under ice chute, and remove ice chute from evaporator. Remove 4 allen head screws holding breaker to evaporator. Allow the auger to dry, the stainless steel of the auger and evaporator must be clean and bright. Clean the auger and evaporator as required. Reverse to reassemble. August 1994 Page 16 FM2400RH SERVICE DIAGNOSIS: Condition - No Ice Being Produced STATUS: NOTHING OPERATES A. Check: Voltage to the unit, restore it if there is none. Check: The master switch, switch ON if off. C. Check: The reset switch, (on the circuit board): depress and release the switch. If the still does not start, check: the spout switch. D. It opens from excess pressure of ice inside the ice chute: this should only happen when the machine does not shut off when the ice storage bin is full. This switch will reset when the ice melts, but the machine will not resart until the reset switch on the circuit board is pressed. E. The machine will not run if there is not enough water in the reservoir. See the next step. August 1994 Page 17 FM2400RH SERVICE DIAGNOSIS: Condition - No Ice Being Produced STATUS: NOTHING OPERATES F. Check: The gear motor, if it will not run, the liquid line valve will not open. If no power to it: Check: The indicator lights on the circuit board, the bin empty light should be ON, the no water light should be OFF . If the bin empty and no water lights are off, check the transformer. Transformer "load" side should have 12 to 15 volts. If not, check the "line" side. The line side should have between 208-230 volts. If the line side has the correct voltage and the load side does not, replace the transformer. If the transformer is good, and the bin empty light is OFF, check the ice level sensors. [. . . ] As you lower the cover onto the lower case, cover will have to be moved closer to the second gear after the output gear has cleared the second gear top bearing. E) After the case is together, and the locating pins are secure in both ends, replace all cap screws. Bench test the gearmotor, check for oil leaks, noise, and amp draw.
