Kenmore 70089 - Manual (Page 23)

Operating Instructions
Normal Operating Sounds
Certain sounds may be made when air conditioner runs,
especially 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.
Compressor cycles frequently. High efficiency
compressors used in new Kenmore Room
AirConditioners run more frequently but for shorter
periods and consume less energy than older, less
efficient compressors.
Airflow from air discharge vent. If sound is distracting,
try adjusting louvers on discharge vent, moving objects
that may be obstructing airflow, or reducing fan speed.
