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. During the freeze cycle water is continuously circulated over the evaporator by the water pump. When the machine enters harvest, the purge valve (not shown) opens and mineral laden water is pumped out of the water trough to the drain.
ICE Series Water System Water Distribution Tube Water is pumped to a distribution tube located at the top of the evaporator and is used to distribute water evenly over the evaporator. The distribution tube can be removed and dissembled for cleaning if the hole becomes plugged or if there is excessive mineral build-up in the water system. The water distribution tube is a tube within a tube. Water enters and fills the inner tube and exits through a series of holes along the top of the inner tube.
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. The actuator tab or wire bale on the splash curtain will release pressure on the bin switch and the machine shuts off. See bin control on page F9.
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. The water pump and purge valve de-energizes once the water is flushed from the water trough. The cam switch controls the length of time that the water pump and purge valve remains energized see page F7.
ICE Series Water System Water Trough The water trough can be easily removed by the following procedures: ICEU150/200 Models 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. 4. Remove water trough mounting screws. 5. Carefully remove water trough from the ice machine. 6. Reverse procedure to reassemble.
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. See refrigerant charge data on page A5–A8. Refrigerant Pressures The suction pressure at the beginning of the freeze cycle can vary +/- 10 psi (.7 bar) depending on operating conditions.
ICE Series Refrigeration System Refrigerant Refrigerant in a high-pressure liquid form is fed to an expansion valve where the refrigerant is reduced to a low-pressure liquid. Under this low pressure, the liquid will absorb heat from the evaporator causing the liquid to change to a vapor. This vapor is then drawn into the compressor where the temperature and pressure of the vapor are increased.
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. As the evaporator fills with liquid refrigerant, the evaporator becomes colder.
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. It is recommended that both valves be replace if one sticks open.
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. It is not necessary to replace the entire evaporator.
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. If a brush is used, brush in the direction of the fins taking care not to bend the fins.
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.
ICE Series Refrigeration System Refrigerant Refrigerant in a high-pressure liquid form is fed to an expansion valve where the refrigerant is reduced to a low-pressure liquid. Under this low pressure, the liquid will absorb heat from the evaporator causing the liquid to change to a vapor. This vapor is the drawn into the compressor where the temperature and pressure of the vapor are increased.
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. The WASH position allows only the water pump to run and is used during the cleaning process to circulate cleaning solution throughout the water system.
ICE Series Electrical System Compressor Check (Continued) If all starting components are good, check the voltage 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. Freeze Timer The freeze time is an adjustable timer used to control the ice bridge thickness. The freeze timer is factory set but may need to be adjusted upon initial start up of the machine.
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.
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. A probe is attached to the rotating clutch and is pushed against the back of the ice slab. The clutch begins to slip when the probe applies approximately 25 ounces of pressure against the ice slab.
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. The tip of the probe should be flush with the back of the evaporator or recessed up the 1/16 of an inch (.16cm). The probe tip must not extend into the freezing area of the evaporator during freeze.
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” as the roller reaches the low part of the cam.
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.
