ICE Series Water System Water Distribution and Components Water enters the machine through the float valve located in the water trough. The water trough holds water used for ice making. The float valve is used to maintain the proper water level in the water trough.
Page 50
ICE Series Water System Water Distribution Disassembly Remove 2 screws holding the distribution tube to the evaporator spillway. Remove the clamp holding the water tube to the distribution tube. Twist the end caps of the distribution tube counterclockwise and pull to remove the inner tube halves from the outer tube. To reassemble, push the inner tube halves into the outer tube with the holes facing the same direction.
Page 51
ICE Series Water System Water Splash Curtain The water splash curtain covers the evaporator to prevent water from splashing into the bin and is also used to actuate the bin switch. When the bin becomes full of ice, the splash curtain is held open when the ice drops off of the evaporator.
Page 52
ICE Series Water System Water Purge Valve When the machine enters the harvest cycle, the water pump continues to run and the purge valve opens. This allows mineral laden water to be pumped from the water trough to the drain. This helps keep the water system clean.
Page 53
ICE Series Water System Water Trough ICEU150/200 Models The water trough can be easily removed by the following procedures: 1. Disconnect power to the ice machine. Mounting Screws 2. Shut the water supply off to the ice machine. 3. Remove water splash curtains when applicable.
ICE Series Refrigeration System Refrigerant Cycle and Components Before diagnosing the refrigeration system, it is very important that the refrigerant charge be correct. Whenever the refrigeration system has been opened, the filter-drier must be replaced and the proper refrigerant charge must be weighed in.
Page 55
ICE Series Refrigeration System Air Cooled Condenser (Self Contained) The air condenser is located in the back of the cabinet. Air is pulled through the condenser by a fan motor and discharged through the right hand side panel. The ICE1400 has 2 fan motors and discharges through the right side and left side panels.
Page 56
ICE Series Refrigeration System Thermostatic Expansion Valve (TXV) The thermostatic expansion valve meters the flow of refrigerant into the evaporator changing its state from a high-pressure liquid to a low-pressure liquid. This drop in pressure causes the refrigerant to cool. The cooled refrigerant absorbs heat from the water circulating over the evaporator.
Page 57
ICE Series Refrigeration System Thermostatic Expansion Valve (Continued) A dual evaporator machine will have one TXV for each evaporator. If one TXV sticks open and the other is operating normally, the suction pressure will be higher than normal and both evaporators will build thick ice.
ICE Series Refrigeration System Note: Permanent discoloration of the evaporator plating is normal and will cause no problems with harvesting the ice or sanitary conditions. Before condemning the evaporator for plating problems, be certain it is not just discoloration. Good evaporators will not be covered under warranty. If the spillway (plastic evaporator top) becomes damaged, it can be replaced.
Page 59
ICE Series Refrigeration System Remote Condenser (Continued) If the airflow is restricted or the condenser is dirty, the head pressure will be excessively high, slow production will result and the compressor may overheat and eventually become damaged. The condenser coil and fan blades must be kept clean. The condenser can be cleaned with compressed air or by using a brush.
ICE Series Refrigeration System Pump Down System (Remote Only) The pump down system prevents liquid refrigerant from migrating to the evaporator and compressor during the off cycle and prevents the compressor from slugging or starting under an excessive load. Liquid Line Solenoid When a machine with a remote condenser shuts off, the liquid line solenoid valve, located at the outlet of the receiver, is de-energized causing the valve to close completely restricting the flow of refrigerant.
Page 61
Most ICE-O-Matic ice machine use R134a or R404a refrigerant. Always check the serial number data plate for the proper type of refrigerant and the amount used in the machine you are servicing.
Page 62
ICE Series Refrigeration System If the refrigeration system is extremely wet, use radiant heat to raise the temperature of the system. This action will cause the moisture to vaporize at less of a vacuum. The use of two (2) valves, one between the vacuum pump and gauge manifold and the other between the refrigerant cylinder and the gauge manifold allows you to evacuate and charge the system without disconnecting any hoses.

ICE Series Electrical System Control Circuit All machines in this manual are electro-mechanical controlled; however the control circuitry on the single evaporator units differs from the dual evaporator units and is detailed below. Selector Switch The selector switch is used to put the machine into the ICE making or WASH cycle or to turn the machine OFF.
Page 68
ICE Series Electrical System Compressor Check (Continued) If all starting components are good, check the amperage draw from the common terminal of the compressor, making sure proper voltage is supplied to the compressor and all wiring is properly connected. If the compressor does not start and there is excessive amperage draw, (see locked rotor amps on compressor tag) the compressor has a locked rotor and should be replaced.
ICE Series Electrical System Untimed Freeze Cycle During the freeze cycle the compressor, water pump and condenser fan motor(s) (if used) are running. On remote systems the liquid line solenoid is also energized, see Refrigeration System. As ice forms on the evaporator, the suction pressure drops. The machine is in the untimed portion of the freeze cycle and will remain in untimed freeze until the suction pressure drops low enough to close the timer initiate control.
ICE Series Electrical System Timed Freeze When the freeze timer is energized, the machine is in the timed portion of the freeze cycle. The freeze timer will time out the remainder of the freeze cycle. Once the time has passed, the machine will enter the harvest cycle.
Page 71
ICE Series Electrical System Harvest Cycle Single Evaporator Machines Once the freeze timer has timed out, power is sent to relay 1 and the machine enters the harvest cycle. Once in harvest motor, the purge valve, hot gas valve and harvest motor are energized. The water pump continues to run during the first part of the harvest cycle so that mineral laden water remaining in the water trough can be pumped through the purge valve to the drain.
Page 72
ICE Series Electrical System Harvest Assist Assembly The harvest assist assembly has several purposes: to assist in moving the ice off of the evaporator, to control the length of harvest and to terminate harvest. When the machine enters harvest, power is sent to the harvest motor which turns a slip clutch.
Page 73
ICE Series Electrical System Probe Tip and Swivel The probe tip is attached to the clutch and makes contact with the back of the ice slab during harvest. The swivel allows the probe tip to pivot as the clutch turns so that the probe is pushed straight through the evaporator probe guide.
Page 74
ICE Series Electrical System Cam Switch Adjustment Check the cam switch for proper adjustment by slowing turning the clutch by hand in a counterclockwise direction while listening for the switch contacts to change. The switch should have an audible “click” as the roller reaches the high part of the cam. Now slowly turn the clutch in a clockwise direction and the switch should have an audible “click”...
ICE Series Electrical System Undercounter machines: A thermostatic bin control is used on the undercounter models. The bin thermostat is located in the control box with a capillary tube, which is in a brass thermo-well mounted to the water trough. When ice comes in contact with the capillary tube thermo-well, the bin thermostat opens and the machine will shut off.
