Service and Parts Manual Warranty Statement On 11-1-98, U-Line Corporation modified the warranty provided with our units. We have significantly improved the coverage of the sealed system in years two through five of the unit’s life. The new warranty covers parts and labor for one year from the date of purchase. In years two through five, from the date of purchase, the warranty covers parts and labor for the entire sealed system.
LIMITED WARRANTY U-Line Corporation warrants each U-Line product to be free from defects in materials and workmanship for a period of one year from the date of purchase; and warrants the sealed system (consisting of the compressor, the condenser, the evaporator, the hot gas bypass valve, the dryer and the connecting tubing) in each U-Line product to be free from defects in materials and workmanship for a period of five years from the date of purchase.
Service and Parts Manual WARRANTY CLAIMS PROCEDURE When submitting claims for warranty payment, please follow these guidelines. You can use any form you would normally use to bill your customer (your own computer generated form, Narda, USA, etc.). The model and serial number MUST be on the claims. Claims will not be paid without a model and serial number. If you work on more than one unit per service call please submit a separate claim for each unit.
SAFETY PRECAUTIONS Do not attempt to service or repair the unit until you have read the entire procedure. Safety items throughout this manual are labeled with Warning or Caution. ! ! Warning means that failure to follow this safety statement may result in extensive product damage, serious personal injury, or death. ! Caution means that failure to follow this safety statement may result in minor or moderate personal injury, property or equipment damage. ! ! DANGER: Risk of child entrapment.
Service and Parts Manual LEVELING AND INSTALLATION REQUIREMENTS The objective of this section is to assist the service technician in diagnosing problems that are related to installation and/or leveling. 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. See Figure A.
GRAVITY DRAIN INSTALLATION ! Plumbing installation must observe all state and local codes.
Service and Parts Manual CONNECTING A DRAIN PUMP ! Plumbing installation must observe all state and local codes. All water and drain connections MUST BE made by a licensed/qualified plumbing contractor. Failure to follow recommendations and instructions may result in damage and/or harm. If a gravity drain connection is not available, and you have not purchased the CLR60 with factory installed pump, install the U-Line P60 drain pump in the rear compartment of the ice maker.
AUTOMATIC CLEAN CYCLE INSTRUCTIONS Automatic Clean Cycle 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 qualified plumber to test the water quality and recommend appropriate treatment. Use only U-Line Ice Machine Cleaner (part number 41978). ! Use only U-Line Ice Machine Cleaner (part number 41978).
Service and Parts Manual U-LINE CLR60 SEQUENCE OF OPERATION On initial start-up or restart (closing of bin thermostat), the toggle switch is in the ice position: 1. The water solenoid valve and hot gas solenoid valve are opened (energized) for 180 seconds (3 minutes). This ensures that the icemaking cycle starts with fresh water, and that the refrigerant pressures are equalized prior to compressor start-up. 2.

Service and Parts Manual THERMISTOR The thermistor senses the refrigeration system “High side” temperature. This is used in conjunction with the control board to determine the length of the freeze and harvest cycles. Thermistors generally fail due to moisture or physical damage. U-Line “high side” thermistors are encased in a specially-designed, moisture-sealed aluminum block. The thermistor is also mounted to the “high side” or “dry” portion of the refrigeration system.
Low Side Pressure Changes The chart above shows the low side pressure changes through the cycles of a CLR60 unit. It shows that during a harvest cycle, the low side pressures climb to nearly 60 psig. When the freeze cycle starts, the pressure quickly drops to approx. 17 psig and throughout the freeze cycle it continues to slowly drop to approx. 7 psig just before the harvest cycle. This unit was operating in a 75° farenheit ambient temperature and the incoming water temperature was 50° farenheit.
Service and Parts Manual ELECTRICAL SPECIFICATIONS S R C STARTING RELAY 3/4" OVERLOAD PROTECTION UL303 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. This would indicate a shorted compressor.

Service and Parts Manual ICE THICKNESS ADJUSTMENT The ice thickness control is factory set to maintain an ice bridge of 1/16" to 1/8". A dimple in each cube is normal. This size cube will break apart from the slab easily as it falls into the ice bin. A fuller cube, with less of a dimple, can be achieved by adjusting the cube size. This will result in a thicker ice bridge. As the ice bridge becomes thicker, the tendency for the cubes to stay together as a slab increases.

Service and Parts Manual TROUBLESHOOTING ! ! NEVER attempt to repair or perform maintenance on the unit until the main electrical power has been disconnected. 1. Unit Does Not Operate (With drain pump; light on control board is not illuminated) Cause ■ No electrical power to the unit ■ Rocker switch set incorrectly ■ Drain tube is kinked or obstructed ■ Bad pump. Diagnose by bypassing the pump. Pull both pink wires from control board and jump the two terminals together.
5. Low Ice Production Cause ■ High ambient temperatures around unit ■ ■ Deposit build-up on evaporator grid ■ ■ Ice thickness dial set incorrectly ■ Dirty condenser coil ■ ■ Remedy Lower ice rate is normal with high ambient temperatures Run the unit through a clean cycle. Use only U-Line Ice Machine Cleaner Adjust ice thickness dial accordingly Clean condenser coil NOTE: Light on control board will indicate if condenser is too dirty.

15. Not Freezing (compressor and fan not operating) Cause ■ No electrical power to unit ■ ■ Rocker switch defective or wired incorrectly ■ IF UNIT HAS P-60 PUMP Cause ■ Drain tube kinked or obstructed ■ Bad pump. Diagnose by bypassing the pump. Pull both pink wires from control board and jump the two terminals together. If unit starts up, then the pump is bad.
