USE AND CARE
PARTS REPLACEMENT
Evaporative cooling works on the principle of heat absorption by moisture evaporation.
Your evaporative cooler draws outside air into specially made pads soaked with water, where the air is
cooled by evaporation, then circulated into your home.
Your MasterCool evaporative cooler has been designed to provide more efficient, consistent cooling
through use of a long-life MasterCool pad. It is a cellulose fiber treated with stiffening and wetting agents
to provide the most reliable evaporative pad ever devised.
Your cooler has two modules - wet and dry - which may be separated for service and cleaning, and
incorporates the most reliable components for long, trouble-free life.
