9 Design ■ Features ■ Performance SER VICING ELECTRICAL SPECIFICA TIONS Compressor Pins To measure start winding resistance, measure across the C-S pins. To measure run winding resistance, measure across the C-R pins. These pins should never measure any resistance to ground. This would indicate a shorted compressor . Specifications FF7.5HBK Com[...]

10 Design ■ Features ■ Performance LEVELING AND INST ALLA TION REQUIREMENTS It is extremely important that the unit is level. If it is not level, the ice mold will not fill evenly . This can cause a reduction in ice rate, uneven sized cubes or water spilling into the storage area which will cause the ice in the bin to melt prematurely . See Fig[...]

11 Design ■ Features ■ Performance GRA VITY DRAIN INST ALLA TION These guidelines must be followed when installing drain lines to prevent water from flowing back into the ice maker storage bin and potentially flowing onto the floor causing water damage: • Drain lines and fittings must have a 5/8" inside diameter . • Drain lines must ha[...]

12 Design ■ Features ■ Performance CONNECTING A DRAIN PUMP If a gravity drain connection is not available, U-Line strongly recommends the use of the U-Line P60 drain pump.
