Sizing Instructions Many complaints about room air conditioners result from units that are over-sized or under-sized for a given area. Over-sized units cool an area before humidity can be adequately removed, so air feels cold and clammy. Under-sized units do not sufficiently cool an area. The following table contains guidelines for properly sizing a room air conditioner for a given area. To size unit: 1.
Installation Installing Room Air Conditioners Proper installation of a room air conditioner helps ensure trouble-free operation, improper installation can result in problems ranging from excessive noise to property or equipment damage.

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.
