    SERVICING Design Features Performance ELECTRICAL SPECIFICATIONS OVERLOAD PROTECTOR STARTING RELAY RELAY COVER CLRCO036 Compressor Pins To measure start winding resistance, measure across the C-S pins. To measure run winding resistance, measure across the C-R pins. These pins should never measure any resistance to ground.

  • Page 10: Leveling And Installation Requirements

    SERVICING Design Features Performance LEVELING AND INSTALLATION REQUIREMENTS It is extremely important that the unit is level. If it is not level, the ice mold will not fill evenly. This can cause a reduction in ice rate, uneven sized cubes or water spilling into the storage area which will cause the ice in the bin to melt prematurely.

  • Page 11: Gravity Drain Installation

    SERVICING Design Features Performance GRAVITY DRAIN INSTALLATION Plumbing installation must observe all state and local codes. These guidelines must be followed when installing drain lines to prevent water from flowing back into the ice maker storage bin and potentially flowing onto the floor causing water damage: •...

  • Page 12: Connecting A Drain Pump

    If your CLRCO2075 is not equipped with a factory installed pump, a P60 drain pump is available through your Dealer, or direct from U-Line. If a pump other than the U-Line P60 drain pump is to be used, it must meet the following specifications: •...

  • Page 13: Self-Cleaning Cycle Instructions

    To maintain operational efficiency, clean unit every six months (depending on water conditions more or less frequent cleaning may be necessary). If the ice maker requires more frequent cleaning, consult a quali- fied plumber to test the water quality and recommend appropriate treatment. Use only U-Line Ice Machine Cleaner (part number 41978).

  • Page 14: Interior Storage Bin Cleaning

    6. Make sure the drain system is working properly and the drain hose is not pinched or kinked. Pour one gallon of cool, fresh water into the ice bin. The water should drain freely. If your CLRCO2075 is equipped with a drain pump, the pump should drain the ice bin.
  • Page 15 However, because there is no thermostat bulb directly on the evaporator as in the other U-Line refrigerators, the controller runs a thirty-minute refrigerator off-cycle, for every 12 hours of clock time. This means the refrigerator side of the unit will not cool during that period even if the refrigerator sensor is calling for cooling.

  • Page 25: Controller

    CONTROLLER IMPORTANT The display and control board on the CLRCO2075 model was designed to be a diagnostic tool. The first thing that should be looked at is the display. Check for flashing lights to indicate that there may be a drain problem or a thermistor problem. If the unit is working properly when you arrive (or when the customer calls to set up service) check the display.
  • Page 26 SERVICING Design Features Performance IMPORTANT 1. Be sure the cycle selector switch (located in the lower right side of the grille) is set to “ON”. Display can be on when selector switch is “OFF”. 2. The controller will be set at the default setting of 38°F when it is first powered up. This setting will display on the LED and should satisfy most customer applications.

    7. COMP 4. H2O PUMP – (water circulating) CLRCO2075 CONTROL BOARD DIAGNOSTICS This section can be used to aid in pinpointing a problem when diagnosing a unit. Every component in the CLRCO unit can be energized separately and its operation verified by following the procedure below. In addition to verifying individual component operation the function of the circuit board can be checked as well.
  • Page 28 SERVICING Design Features Performance Compressor COMP To energize the compressor touch the previously disconnected pink lead back to the board. You should hear the compressor start up and the green COMP light will illuminate. If it does not start check voltage at the compressor and at the output from the board. If the green light does not illu- minate first remove both pink wires from the board and directly jump the two spade connectors together.

    Do not touch electrical wires. Disconnect power to the ice maker before making any ice thickness adjustments. Your U-Line Clear Ice Maker uses advanced technology to make ice that is crystal clear. This technology cascades a flow of water over a chilled ice mold that is mounted vertically so no water sits in it.
