    INITIAL START UP, CHECKS AND ADJUSTMENT INSTRUCTIONS NOTE: Do not start the Unit before completing the previous Installation steps. Turn on the water supply and main power switch (located on top of the electrical box). NOTE: If the Unit will not start, be sure the water reservoir is full. The low water safety control must be properly adjusted to start and shut down the Unit.

    GUIDE TO SERVICE IMPORTANT: Prventive maintenance can increase the trouble-free life of your Ice Maker. Failure to perform preventive maintenance could void your equipment warranty. ICE MAKER CLEANING AND SANITIZING PROCEDURES IMPORTANT: Do not use any of the ice made during cleaning operations. Clean and sanitize ice storage area when cleaning Ice Maker.

    2. Check the drain tubes for clogs and ”aged” tubes. Replace if tubes are stained or brittle. FIGURE 2. AUGER ASSEMBLY 3. Check for signs of condensation. Clean where necessary and replace insulation properly. 4. Check safety circuits for proper operation. 5.

  • Page 11: To Replace Water Level Control

    TO REPLACE WATER LEVEL CONTROL 1. Shut off the water supply. Shut off the main power switch or unplug the Ice Maker from electrical outlet. 2. Remove flexible tubing from bottom of the water level control, then drain water from the water level control and evaporator.

  • Page 12: Refrigeration Systems

    REFRIGERATION SYSTEMS REFRIGERATION SYSTEM ADJUSTMENTS A complete understanding of the Ice Maker and the 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.

  • Page 14: Condenser Modulating Valve Removal

    NOTE: Cold water will absorb more heat faster than warm water. The water flow will therefore automati- cally increase as inlet temperature increases. CONDENSER MODULATING VALVE REMOVAL 1. Disconnect power to unit, shut off water supply to condenser, then reclaim refrigerant from system. 2.

    Voltage – The voltage should be within 10% of the rated nameplate voltage. High compressor amperage draw, it should never exceed 120% of the rated nameplate amperage. See Electrical Checkout Instructions. 3. THE COMPRESSOR RUNS BUT WILL NOT REFRIGERATE Check the compressor suction and discharge pressures. See TEMPERATURE/PRESSURE CHART.
