User manual SCOTSMAN FME1500R

[. . . ] FME1500R INTRODUCTION 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. Table of Contents FOR THE INSTALLER: Remote Condenser . 8 FOR THE INSTALLER: Completed Installation . . 9 FOR THE INSTALLER: Final Check List . 20 SERVICE DIAGNOSIS: Condition - No Ice Being Produced . [. . . ] If the pressures rise above the trip out point, and the unit shuts down: a. If the air flow is poor because of the installation, advise the user that the unit should be moved, or the air around it kept cooler. Check the fan motor for tight bearings and proper rotation. Check that the fan blades are clean, and the fan secure to the fan motor shaft. Check the head pressure control valve, it should be maintaining a head pressure above 180 psig. If the unit has the correct charge, and the condenser is clean, and the refrigerant lines are not kinked or twisted, and the condenser is not overheated by external heat loads, the head pressure should be under the trip out point of the head pressure control switch. If all of the above are found to be good, and the machine trips out on high head pressure, replace the head pressure control valve. G. If there is not enough water in the reservoir, the water level sensor will keep the machine from starting. a. Check the water level, restore/adjust if low. Check the water level sensor, clean if dirty, (see maintenance). If the machine does not start, see the next page. June 1994 Page 22 FME1500R SERVICE DIAGNOSIS: Condition - No Ice Being Produced STATUS: NOTHING OPERATES F. Check: The gear motor, if it will not run, the compressor will not run. 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 . 1. 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. Remove sensors by sliding them sideways out of the ice chute. Look through the ice chute "eye" hole for something blocking the ice chute. If the unit still does not run, replace the ice level sensors. [. . . ] Allen · If gauges must be used, use very short hoses to Wrench minimize refrigerant discharged into the air. · Refrigerant should not be added except as a way to determine the proper operation of the product. If the system was low on refrigerant, Torque Stem to there is a leak, and it must be found and Torque 6-8 ft. · This system has a critical charge, it must be Torque Stem Cap to 8-12 ft. [. . . ]
