Page 9: Icemaker Cleaning And Sanitizing Procedures
ICEMAKER CLEANING AND SANITIZING PROCEDURES Do not use any of the ice made during cleaning operations. Clean and sanitize ice storage area when cleaning icemaker. 1. Turn machine off. 2. Shut off water supply. 3. Remove ice from storage bin. 4. -
Page 10: Semi-Annually
SEMI–ANNUALLY Semi–Annually in addition to all previously established service procedures perform the following: 1. Check for water leaks; tube connections, water fillings and lower icemaker water seal. 2. Check drain tubes for clogs and “aged” tubes. Replace if tubes are stained or brittle. 3. -
Page 11: Water Level Control
WATER LEVEL CONTROL HOW WATER LEVEL CONTROL WORKS When water is introduced through the inlet fitting the float rises, the float pushes against a lever that in turn, forces the poppet assembly against the inlet fitting valve seat that seals the water off. See Figure 1. Before the water inlet is sealed, the safety switch is operated. -

REFRIGERATION SYSTEMS REFRIGERATION SYSTEM ADJUSTMENTS A complete understanding of the icemaker and hermetic refrigeration system is necessary before any adjustments are made. The refrigeration technician must use high and low side pressure readings, water and air temperatures, plus general conditions of cleanliness to assess the refrigeration system status when making any adjustments. -

TROUBLESHOOTING IMPORTANT: Only qualified personnel should service internal components or electrical wiring. TROUBLESHOOTING GEAR MOTORS Basically, Gear motor problems can be narrowed down to three areas of checkout. THE GEARMOTOR WILL NOT RUN 1. No voltage to the transmission terminals – check external circuit. 2. -
Page 16: Overload Check
OVERLOAD CHECK: 2. Allow motor to cool and reset overload if necessary. 3. Remove motor end bell and stator, if necessary. 4. Check terminals 1 and 3 on overload. No continuity replace overload. Use a volt–ohm meter. See Figures 5 and 6. -
