ICEU070A INTRODUCTION This manual provides the specifications and the step-by-step procedures for the installation, startup, operation, maintenance and cleaning for the ICEU070A ice machine. NOTE. To retain the safety and performance built into this ice machine, it is important that installation and maintenance be conducted in the manner outlined in this manual.
ICEU070A Specifications The ice machine must be installed indoors in a controlled environment. Minimum Ice-O-Matic reserves the right to make design changes and/or improvements at any time. Specifications and design are subject to change without notice. Maximum 0 Air Temp 50 F. 950F. Water Temp 400F. 1000F. Water Pressure 20 PSI 80 PSI Voltage 103.5 126.5 UNPACKING AND INSPECTION 1. Call your authorized Ice-O-Matic Distributor or Dealer for proper installation. 2.
ICEU070A General Information And Installation This model is supplied from the factory completely pre-wired and requires only electrical power connections to the wire cord provided at rear of the unit. To keep your Ice-O-Matic ice machine at peak performance levels, periodic maintenance checks must be carried out as indicated on the Maintenance and Cleaning section of this manual. Make sure that the ice machine is connected to its own circuit and individually fused (see data plate for maximum fuse size).
ICEU070A Water Supply And Drain Connections General Water Drain When choosing the water supply for the ice cuber consideration should be given to: The recommended drain tube is a plastic or flexible tube with 18 mm (3/4") I.D. which runs to an open trapped and vented drain. a) Length of run b) Water clarity and purity c) Adequate water supply pressure Low water pressure, below 20 psi may cause a malfunction.
ICEU070A Final Check List 1. Is the unit in a room where ambient temperatures are above a minimum of 10oC (50 oF) even in winter months? 8. Have the bolts holding the compressor down been checked to ensure that the compressor is snugly fitted onto the mounting pads? 2. Is there at least a 15 cm (6") clearance around the unit for proper air circulation? 9. Have the bin liner and cabinet been wiped clean? 3. Is the unit level? (IMPORTANT) 10.
ICEU070A Operating Instructions Start Up NOTE. During the charging cycle, the water inlet solenoid valve is energized. The water flows through the valve to the back side of the evaporator platen and then down to fill up the ice machine sump for the next freezing cycle. After having correctly installed the ice maker and completed the plumbing and electrical connections, perform the following “Start-up” procedure. A.
ICEU070A Operational Checks E. The unit now starts its first freezing cycle with the following components in operation: Remove the ice from the storage bin thermostat. The ice maker should restart automatically in three-four minutes. · Compressor · Water Pump · Fan Motor NOTE. The bin thermostat is factory set at 1oC (35oF) OUT and 4oC (39oF) IN. M. Re-attach the front panel, then instruct the owner/user on the general operation of the ice machine and about the cleaning and care it requires. F.
ICEU070A Component Description Water Pump The water pump operates continually throughout the freezing cycle. The pump forces the water from the sump to the spray system and through the spray nozzles so it sprays into the inverted cup molds to be frozen into crystal clear ice cubes. Water Inlet Solenoid Valve The water inlet solenoid valve is energized only during the defrost cycle.
ICEU070A Operation - Electrical Sequence The following charts illustrate which switches and components are ON or OFF during the two phases of the icemaking cycle. Refer to the wiring diagram for reference.
ICEU070A Freeze Cycle Average Discharge Pressure · A/C: 100 to 155 PSIG Suction Pressure · End Freeze Cycle: 0 to 1.5 PSIG Refrigerant Metering Device: · Capillary tube Refrigerant Charge (R-134a) · 9.5 oz. The thermostat sensing bulb is located into a plastic tube (bulb holder) secured by two clips directly to the evaporator serpentine. This control determines the length of the freezing cycle and correspondingly the size of the cubes.
ICEU070A Cleaning Switch Located on the bottom side of the control box, it is used to energize the water inlet and the hot gas valves to fill the sump of the machine with water when needed.
ICEU070A Service Diagnosis SYMPTOM POSSIBLE CAUSE SUGGESTED CORRECTION Unit will not run Blown fuse Replace fuse & check for cause of blown fuse.
ICEU070A Service Diagnosis SYMPTOM POSSIBLE CAUSE SUGGESTED CORRECTION Irregular cubes size & some cloudy Some jets plugged Remove jet cover and clean. Shortage of water See shortage of water. Unit not leveled Level as required. Poor pumping Check and/or replace the water pump. Cubes too large Cube size control set improperly Check and adjust for proper operation. Decreased ice capacity Inefficient compressor Replace. Leaky water valve Repair or replace.
ICEU070A Maintenance And Cleaning Instructions GENERAL Clean - Replace Of Air Condenser Filter The periods and the procedures for maintenance and cleaning are given as guides and are not to be construed as absolute or invariable. Cleaning, especially, will vary depending upon local water and ambient conditions and the ice volume produced; and, each ice machine must be maintained individually, in accordance with its particular location requirements. 1.
ICEU070A Cleaning Water System 1. Remove the ice from the bin. 2. Remove the air filter and then the front panel. 3. Rotate control knob counter clockwise to the Off position. 4. Turn off the water supply to the ice machine. 5. Remove top panel. 6. Remove plastic panel (evaporator cover) that covers evaporator section. 7. Remove clamp and drain cap from the bottom of the reservoir, allow all the water to drain out. Pour Scale Remover Over The Evaporator Section 13.
ICEU070A 23. Rotate the control knob to the Normal position. 24. Operate the machine with the cleaning toggle switch in the Operation position for 4 minutes. 29. Thoroughly spray or wipe the interior of the ice storage bin, bottom of the evaporator cover and the spray platform with the sanitizing solution. 30. Completely immerse the curtain in the sanitizing solution. 25. Switch the cleaning toggle switch to the Cleaning position and operate the machine for 1 minute. 26. Repeat steps 23 and 24 five times.
