■ The current air conditioner replaced an older model. The use of more efficient components may cause the air conditioner to run longer than an older model, but the total energy consumption will be less. Newer air conditioners do not emit the “blast” of cold air you may be accustomed to from older air conditioners, but this is not an indication of lesser cooling capacity or efficiency. Refer to the efficiency rating (EER) and capacity rating (in Btu/h) marked on the air conditioner.
■ The air conditioner is in a heavily occupied room, or heatproducing appliances are in use in the room. Use exhaust vent fans while cooking or bathing and try not to use heatproducing appliances during the hottest part of the day. A higher capacity air conditioner may be required, depending on the size of the room being cooled.

Air conditioner cycles on and off too much or does not cool room in cooling mode

■ The air conditioner is not properly sized for your room. Check the cooling capabilities of your room air conditioner. Room air conditioners are not designed to cool multiple rooms.
■ The filter is dirty or obstructed by debris. Clean the filter.
■ There is excessive heat or moisture (open container cooking, showers, etc.) in the room. Use a fan to exhaust heat or moisture from the room. Try not to use heatproducing appliances during the hottest part of the day.
■ The louvers are blocked. Install the air conditioner in a location where the louvers are free from curtains, blinds, furniture, etc.
■ The outside temperature is below 61°F (16°C). Do not try to operate your air conditioner in the cooling mode when the outside temperature is below 61°F (16°C).
■ The temperature of the room you are trying to cool is extremely hot. Allow extra time for the air conditioner to cool off a very hot room.
■ Windows or doors to the outside are open. Close all windows and doors.
■ The Temperature control is not at a cool enough setting. Adjust the TEMP/TIME control to a cooler setting by pressing the minus button to reduce the temperature. Set the Fan Speed control to the highest setting.

Water drips from cabinet into your house

■ The air conditioner is not properly leveled. The air conditioner should slope slightly downward toward the outside. Level the air conditioner to provide a downward slope toward the outside to ensure proper drainage. See the Installation Instructions.
NOTE: Do not drill a hole into the bottom of the metal base and condensate pan.
