Operating Instructions

Normal Operating Sounds

Certain sounds may be made when air conditioner runs, especialJy in a cooling mode. Sounds may include:

•Water splashing onto condenser; caused by slinger ring attached to condenser fan. Slinger ring picks up water (condensate) in base pan and sprays it on condenser to increase efficiency of unit.

•Compressorcycles frequently. High efficiency compressors used in new Kenmora Room AirConditionersrun more frequently but for shorter periods and consume less energy than older, less efficientcompressors.

•Airflowfrom air discharge vent. If sound is distracting,

try adjusting louvers on discharge vent, moving objects that may be obstructing airflow, or reducing fan speed.
