Do not block the intake area, or heat may build up and could cause a fire. • Clean the filter periodically. For details, refer to "Cleaning and Replacing the Filter" on page 59. Deposition of dirt on the filter works to reduce the cooling effect, causing heat to build up inside, which could cause a fire or malfunction. 4 AC IN (power input) terminal This is the power input terminal where the supplied power cord is connected.
