CLR2160, CLRCO2175 158. When water begins flowing over the evaporator(approximately 3 minutes), pour 1 packet of CLR cleanerinto the water trough. The cleaning process will lastapproximately 45 minutes.Figure 239. Following the cleaning process, sanitize the ice bin witha bleach solution.Dilute 1 tablespoon bleach in 1 gallon of warm water.Apply this solution to the entire inside of the storagearea. Then rinse thoroughly with water.The unit will resume operation approximately 15 minutesafter the automated cleaning process is completed. Thewater fill valve will energize, fill the water reservoir, andshut-off after three minutes. The compressor begins tooperate and water flows over the evaporator assembly(ice cube tray). Initially, the water flow may not beuniform, causing uneven sized cubes or water to spill intothe ice storage bin. This is a normal situation that willcorrect itself within the first 24 hours of operation.IMPORTANTIMPORTANT• Discard all ice produced in the first harvest.• Should power to the unit be interrupted duringthe self-clean cycle, it will be necessary to repeatthe complete cleaning cycle after power isrestored.Ice Cube Thickness AdjustmentINTERVAL - AS REQUIREDIce thickness adjustments are made using the controlpanel as follows:1. To enter the thickness adjustment mode:a. Touch and hold the UP ARROW button.b. Touch and release the DOWN ARROW button threetimes, then release the UP ARROW button.c. The display will switch to “0” to confirm thethickness adjustment mode has been selected.2. The factory setting is “0,” and the total range ofadjustment is -5 to +5 (ideal range is -1 to +1). Use theUP ARROW button to raise the setting and thicken theice bridge, or the DOWN ARROW button to lower thesetting to thin the ice bridge.IMPORTANTIMPORTANTIce thickness adjustment should only be made oneincrement at a time. Allow ice maker production tostabilize for 24 hours before rechecking icethickness.3. Touch and release the LIGHT button key to exit the icethickness adjustment mode.4. Remove all ice from the storage bin.Figure 24Ice cubes in any given batch will vary, so it is necessary tochoose cubes from the sample area for comparison whenmaking adjustments. If further adjustments are desired,repeat Steps 1 through 4.The ice cube thickness is factory set for best overallperformance. The factory setting is designed to maintainan ice bridge of approximately 1/16" to 1/8" under normalconditions resulting in a dimple of approximately 1/4" to1/2" in depth. A fuller cube with less of a dimple results ina thicker ice bridge. As the ice bridge becomes thicker, thetendency for the cubes to stay together as a slabincreases. A bridge thicker than 1/8" may cause cubes tooverfill the ice bucket.BrushDIMPLESULIN_0299_AICE BRIDGEIce Bridge and Dimples
