CLR2160, CLRCO2175 11Figure 17All models incorporate rigid foam insulated cabinets toproved high thermal efficiency and maximum soundreduction for the internal working components. In spiteof this technology, the unit may make sounds that areunfamiliar.Normal operating sounds may be more noticeablebecause of the unit’s environment. Hard surfaces such ascabinets, wood/vinyl/tiled floors and paneled walls have atendency to reflect normal appliance operating noises.Common refrigeration components, and a briefdescription of the normal operating sounds they make,are listed below.Note: Your unit may not contain all the componentslisted.• Compressor: The compressor makes a hum or pulsingsound that may be heard when it operates.• Evaporator: Refrigerant flowing through anevaporator may sound like boiling liquid.• Condenser Fan: Air moving through a condenser maybe heard.• Automatic Defrost/Drain Pan: Water may be hearddripping or running into the drain pan when the unit isin the defrost cycle.• Automatic Ice Maker: Ice can be heard as it drops fromthe mold into the ice bin/tray.• Water Valve: The water valve will make an occasionalbuzzing sound and running water will be heard.Some U-line models are designed to operate in outdoorenvironments.
