Energy Saving Guide
• Be sure to unplug the air conditioner to prevent shock or re hazard. The cabinet and front may be dusted
with an oil-free cloth or washed with a cloth dampened in a solution of warm water and mild dishwashing
detergent. Rinse thoroughly and wipe dry.
• Never use harsh cleaners, wax, or polish on the cabinet front.
• Be sure to wring excess water from the cloth before wiping around the controls. Excess water in or around the
controls may cause damage to the air conditioner.
• High Pitched Chatter-High eciency compressors may have a high pitched chatter during the cooling cycle.
• Sound of Rushing Air-At the front of the unit, you may hear the sound of rushing air being moved by the fan.
• Gurgle/Hiss-Gurgling or Hissing noises may be heard due to refrigerant passing through the evaporator during
normal operation.
• Vibration-The unit may vibrate and make noise because of poor wall or window construction or incorrect
installation.
• Pinging or Switching-Droplets of water hitting the condenser during normal operation may cause these
sounds.

studio or warehouse.
• Make sure the unit is secure in the window with no gaps where air can escape.

shutting it o.
• Inspect and keep the air lters clean by cleaning regularly.
