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.

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.

Troubleshooting The following table describes some common problems that may be encountered with a room air conditioner. Each problem is accompanied by several possible causes and solutions. Problem Possible Cause Solution Unit will not turn on. • Power cord unplugged. • Ensure power cord is firmly plugged into outlet. ■ Replace blown fuse; reset tripped breaker. • Low voltage protection prevents operation if supply voltage drops below 90 VAC for 115 volt units; 171 VAC for 230 volt units.
Troubleshooting Problem Possible Cause Solution Unit does not adequately cool room or area. • Desired temperature set too high. • Reduce temperature setting to more comfortable level. • Close blinds or curtains on windows exposed to direct sunlight. Vent steam from open cooking containers, showers, etc., from cooling area. Avoid use of heatproducing appliances during hottest part of day. • Clean coils. See Maintenance Procedures. • Excessive heat or moisture in area.
