GEMD270A GENERAL INFORMATION AND INSTALLATION LOCATION AND LEVELING UNPACKING AND INSPECTION 1. Call your authorized Ice-O-Matic Distributor or Dealer for proper installation. 2. Visually inspect the exterior of the packing and skid. Any severe damage noted should be reported to the delivering carrier and a concealed damage claim form filled in subject to inspection of the contents with the carrier’s representative present. 3. a) Cut and remove the plastic strip securing the carton box to the skid. WARNING: This Ice Dispenser is designed for indoor installation only. If the machine is operated...

GEMD270A ELECTRICAL CONNECTIONS See data plate for current requirements to determine wire size to be used for electrical connections. All Ice-O-Matic ice machines require a solid earth wire. This Ice-O-Matic ice machine is supplied from the factory completely pre-wired and only needs to be plugged into a nearby 115 volt outlet. Make sure that the ice machine is connected to its own circuit and individually fused (see data plate for fuse size). The maximum allowable voltage variation should not exceed -10% and +10% of the data plate rating. Low voltage can cause faulty functioning and may be responsible...

GEMD270A WATER SUPPLY AND DRAIN CONNECTIONS GENERAL WATER DRAIN When choosing the water supply for the ice flaker, consideration should be given to: The recommended drain tube is a copper, rigid plastic or reinforced flexible tubing (supplied) with .75" (19mm) I.D. which runs to an open trapped and vented drain. When the drain is a long run, allow1/4" drop per foot. a) Length of run b) Water clarity and purity c) Adequate water supply pressure Note: Although soft, easily kinked vinyl tubing is not recommended for a drain, a short length of ¾” ID vinyl tubing is required to connect a rigid drain...

GEMD270A FINAL CHECK LIST 1. Is the unit in a room where the ambient temperatures are within a minimum of 50°F even in winter months? 2. Is there at least a 6" clearance around the unit for proper air circulation? 3. Is the unit level? 4. Have all the electrical and plumbing connections been made, and is the water supply shut-off valve open? 5. Has the voltage been tested and checked against the data plate rating? 6. Has the water supply pressure been checked to ensure a flowing water pressure of at least 20 psi. 7. Check all refrigerant lines and conduit lines to guard against vibrations and...

GEMD270A OPERATING INSTRUCTIONS INITIAL START UP After having correctly installed the ice machine and completed the plumbing and electrical connections, perform the following “Start-up” procedure. Remove the control board inspection panel and cover to view the lights on the control board. A. Open the water supply line shutoff valve and turn the main switch on the power supply line to the ON position. The GREEN LED will glow to signal that unit is under power. B. After 3 minutes have elapsed – the stand by period – the unit starts operating by activating systems in following sequence: 1. GEAR...

GEMD270A INITIAL START UP CONTINUED NOTE: If the evaporating temperature has not dropped lower than 30° F within ten minutes of compressor start-up, the evaporating temperature sensor will detect the abnormal temperature and stop the unit operation. In this circumstance, the 3rd warning YELLOW LED will blink (Fig.3). After diagnosing and eliminating the cause of the poor evaporating temperature (insufficient refrigerant in the system, inoperative compressor or inoperative evaporator sensor), push the RESET BUTTON on the control board. Before resuming operation the unit will go through the usual...

GEMD270A signaling that there is a full storage bin (Fig.6). After diagnosing and fixing the cause of the temperature rise, push the RESET BUTTON on the control board. Before resuming operation the unit will go through the usual 3 minute STAND-BY period. E. Check for the correct CUT-OUT and CUT-IN of the float reservoir water level sensors by shutting off the valve on the water supply line. This will cause a gradual decrease of the water level in the float reservoir and as soon as the level gets below the sensors, the flaker stops operating and the 5th YELLOW WARNING LED will glow to signal the...
