Ice
ICE CUBE THICKNESS AND ADJUSTMENT
NOTICE Ice thickness adjustment should only be made one increment at a time. Allow ice maker production to stabilize for 24 hours before rechecking ice thickness.
Ice is produced in layers resulting in a clear cube. Ice in bin may develop surface frost which disappears when cube is placed in liquid.
Ice cubes in any given batch will vary, so it is necessary to choose cubes from the sample area for comparison when making adjustments.
The ice cube thickness is factory set for best overall performance. The factory setting is designed to maintain an ice bridge of approximately 1/16″ to 1/8″ (1.6 mm to 3.2 mm) under normal conditions, resulting in a dimple of approximately 1/4″ to 1/2″ (6.4 mm to 12.7 mm) in depth. A fuller cube with less of a dimple results in a thicker ice bridge. As the ice bridge becomes thicker, the tendency for the cubes to stay together as a slab increases. A bridge thicker than 1/8″ (3.2 mm) may cause cubes to overfill the ice bucket.
32 ice cubes are formed on a 4 x 8 slab during each cycle. Each cycle takes approximately 15-20 minutes at the default cube thickness (0).

Cleaning

EXTERIOR CLEANING Vinyl Clad (Black or White) Models Clean surfaces with a mild detergent and warm water solution. Do not use solvent-based or abrasive cleaners. Use a soft sponge and rinse with clean water. Wipe with a soft, clean towel to prevent water spotting.
Clean any glass surfaces with a non-chlorine glass cleaner.
Stainless Models
Stainless door panels, handles and frames can discolor when exposed to chlorine gas, pool chemicals, saltwater or cleaners with bleach.
Keep your stainless unit looking new by cleaning with a good quality all-in- one stainless steel cleaner and polish monthly. For best results use Claire® Stainless Steel Polish and Cleaner. Comparable products are acceptable. Frequent cleaning will remove surface contamination that could lead to rust. Some installations may require cleaning weekly.
Do not clean with steel wool pads.
Do not use stainless steel cleaners or polishes on any glass surfaces.
Clean any glass surfaces with a non-chlorine glass cleaner.
Do not use cleaners not specifically intended for stainless steel on stainless steel surfaces (this includes glass, tile, and counter cleaners).
If any surface discoloring or rusting appears, clean it quickly with Bon-Ami® or Barkeepers Friend Cleanser® and a nonabrasive cloth. Always clean with the grain. Always finish with Claire® Stainless Steel Polish and Cleaner or comparable product to prevent further problems.

Using abrasive pads such as ScotchBriteTM will cause the graining in the stainless steel to become blurred.
Rust not cleaned up promptly can penetrate the surface of the stainless steel and complete removal of the rust may not be possible.

NOTICE
Use only U-Line Clear Ice Machine Cleaner (80-55667-00), available for purchase from u-line.com or your dealer. It is a violation of federal law to use this solution in a manner inconsistent with its labeling. Use of any other cleaner can ruin the finish of the evaporator and will void the warranty. Read and understand all labels printed on the package before use.

U-Line Clear Ice Machine Cleaner is used to remove lime scale and other mineral deposits. Refer to the following steps to initiate the self-cleaning cycle.

! CAUTION

Never use anything to force ice from the evaporator. Damage may result.

1. Turn the ice machine off and allow any ice to melt off of the evaporator.

2. Remove all ice from the storage bin.

3. Remove evaporator cover.
4. Remove the standpipe by lifting it up while using a slight back and forth motion to loosen it from the drain hole. The water in the reservoir will flow down the drain.

Evaporator cover

5. Re-install the standpipe into the water trough.

6. Clean the Interior Bin as follows:

Evaporator

· Dilute 1-2 oz. of Clear Ice Machine Cleaner into two quarts of water.

Standpipe

Water trough

· Using a sponge or cloth, clean interior of ice bin, tubing and door. This cleaner will remove all mineral deposits and other contaminants from the surfaces.

8. Place unit into CLEAN mode by holding seconds.

for 5

9. When water begins flowing over the evaporator (approximately 3 minutes), pour 1-2 oz. of Clear Ice Machine Cleaner into the water trough. The cleaning process will last approximately 45 minutes.

10. Dilute 1 tablespoon bleach in 1 gallon of warm water. Apply this solution to the entire inside of the storage area. Then rinse thoroughly with water.

The unit will resume operation approximately 15 minutes
after the automated cleaning process is completed. The water fill valve will energize, fill the water reservoir, and shut-off after three minutes. The compressor begins to operate and water flows over the evaporator assembly (ice mold). Initially, the water flow may not be uniform,
causing uneven sized cubes or water to spill into the ice
storage bin. This is a normal situation that will correct itself within the first 24 hours of operation.

NOTICE Discard all ice produced in the first harvest.
Should power to the unit be interrupted during the self-clean cycle, it will be necessary to repeat the complete cleaning cycle after power is restored.
REFRESH KIT
Due to variations in water quality or inadequate maintenance your unit may become excessively coated in lime scale or calcium. U-Line offers a cost effective refresh kit which replaces many interior components and will return your unit to like new condition.

USER GUIDE

Thermistors
Thermistors are used for various temperature readings. Thermistors provide reliable temperature readings using a resistance which varies based on surrounding temperatures. If a faulty thermistor is suspected it may be tested using an accurate ohmmeter.
Both thermistors in the unit are identical. If a thermistor is suspected of being defective, the resistance can be verified. Place the thermistor in an ice water bath, the resistance should read 16.1k Ohms +/-5% on your meter.
Thermistor connections must be kept clean. A thermistor connection that has become corroded can cause resistance values from the thermistor to change as they pass through a dirty connection to the board.
It is for that reason that we apply dielectric grease to all of our thermistor connections. Dielectric grease will help to keep thermistor connections clean and dry.
If you change a thermistor in the unit please re-apply dielectric grease to the connection. If you encounter a dirty thermistor connection, you should replace the thermistor and the thermistor harness.
Thermistor error information can be found in the Control Operations – Service section.
This unit has two thermistors.
Thermistor one (Zone): Located along the right hand side wall. It is used to maintain the operating temperature within that zone.
Thermistor two (Evaporator): Located on the evaporator. It is used for defrost.
THERMISTOR FAILURE
Zone Thermistor If the zone thermistor in the unit fails, the unit will continue to cool in a backup mode (Self Preservation Mode) to preserve the integrity of the contents. The unit will otherwise operate normally.

Evaporator Thermistor

If the evaporator thermistor fails, the unit will rely on a preset defrost timer during defrost cycles. The unit will otherwise operate normally. Refer to defrost section.
