Water System Page D1 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.
Water System Page D2 Water Distribution Disassembly Remove 2 screws holding the distribution tube to the evaporator spillway. Remove the clamp holding the water tube to the di stribution tube. Twist the end c aps of the distribution tube counterclockwise and pull to remove the inner tube halves from the outer tu be.
Water System Page D3 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.
Water System Page D4 Water Purge Valve When the machine enters the harvest cycle, the water pump continues to ru n 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.
Water System Page D5 Water Trough The water trough can be easily removed by the following procedures: Mounting Screws CCU0150/0220 Models 1. Disconnect power to the ice machine. 2. Shut the water supply off to the ice machine. 3. Remove water splash curtains when applicable.
Refrigeration System Page E1 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.
Refrigeration System Page E2 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 mo tor and discharged through the right hand side panel. The CCM1448 has 2 fan motors and discharges through the right side and left side panels.
Refrigeration System Page E3 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.
Refrigeration System Page E4 Thermostatic Expansion Valve (Continued) A dual evaporator machine will have one TXV fo r each evaporator. If one TXV sticks open and the other is operating normally, the suction pressu re will be higher than normal and both evaporators will build thick ice.
Refrigeration System Page E5 Note: Permanent discoloration of the evaporator plating is normal and will cause no problems with harvesting the ice or sanitary conditions. Befo re condemning the evaporator for plating problems, be certain it is not just discolorati on.
Refrigeration System Page E6 Remote Condenser (Continued) If the airflow is restricted or the condenser is di rty, the head pressure will be excessive ly high, slow production will result and the compressor may overheat and eventually become damaged. The condenser coil and fan blades must be kept clean.
Refrigeration System Page E7 Pump Down System (Remot e Only) The pump down system prevents li quid refrigerant from migrat ing to the evaporator and compressor during the off cycle and prevents the co mpressor from slugging or starting under an excessive load.
Refrigeration System Page E8 Refrigerant Refrigerant in a high-pressure liq uid 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.
Refrigeration System Page E9 If the refrigeration system is ex tremely wet, use radiant heat to raise the temp erature of the system. This action will cause the moistu re to vaporize at less of a vacuum.

Electrical System Page F1 Control Circuit All machines in this manual are electro-mechanical controlled; howev er the control circuitry on the single evaporator units diffe rs from the dual evaporator units and is detailed below.
Electrical System Page F2 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.
Electrical System Page F3 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 energi zed, see Refrigeration System. As ice forms on the evaporator, the suction pressure drops.
Electrical System Page F4 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.
Electrical System Page F5 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.
Electrical System Page F6 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.
Electrical System Page F7 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 pivo t as the clutch turns so that the probe is pushed straight through the evaporator probe guide.
Electrical System Page F8 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.
Electrical System Page F9 Undercounter machines: A thermostatic bin control is used on the undercounter models. The bin thermostat is located in the c ontrol box with a capillary tube, wh ich is in a brass thermo-well mounted to the water trough.
