How and Why
Your room air conditioner provides the following functions to make hot weather
living more comfortable:
• Cools and circulates room air.
• Lowers humidity by removing excessmoisture.
• Filtersout summertime dust, dirt, and some airborne impurities.
The air conditioner performs these functions by drawing room air through a filter
which traps dust and dirt particles. The air then passesover a cooling coil which
refrigerates the air and removes excessmoisture. The same air is then returned to
the room -- cooler, drier and cleaner, Moisture removed from the room air iscarried
to the outside and evaporated.
Your air conditioner is designed to be easy to operate and to provide plenty of
cooling power.
