It is necessary to clean your air filter and front panel properly for top performance and cleaner air.
Cleaning
1. Unplug the power cord. 2. Remove the front panel from the cabinet for easy cleaning. Press down on the top of the front panel and tilt forward. Lift the front panel up and away from the bottom spring clips. See Figure 6. 3. Remove the air filter and clean it separately if needed. (See �Cleaning the air filter� on page 14.) 4. Using a soft cloth, clean the front panel with warm water and a mild soap or detergent. Rinse and dry thoroughly. Wipe the control panel with a soft, dry cloth. 5. Replace the front panel. Set the bottom of the panel on the cabinet spring clips. Push down and forward into the cabinet to secure upper tabs. 6. Plug in the power cord.

sounds
When your air conditioner is operating normally, you may hear such sounds as: l A �pinging� sound caused from water droplets hitting the condenser. This is an energy efficient design whereby the water cools the condenser. l Air movement from the fan. l Clicks from the thermostat cycling on and off. l Vibrations or noise due to poor wall or window construction. l A high pitched hum or pulsating noise caused by the modern high efficiency compressor cycling on and off.
