READ CAREFULLY ALL OF THIS MANUAL BEFORE INSTALLING THE UNIT
Evaporative cooling is nature’s way of cooling. When air is
moved over a wet surface, water is evaporated and heat is
absorbed. When stepping out of swimming pool with the
wind blowing, evaporative cooling makes you feel cool, even
though the air may be warm.
This unit works on the same principle. Air is drawn across
wet fi lter pads where the air is cooled by evaporation and then
circulated throughout the building. It is this combination of
cooled air and the movement of air over the skin which makes
it feel cool.
Unlike refrigeration systems which recirculate the air, an
evaporative cooler continually brings in fresh air while
exhausting old air. You are completely replacing the air every
2 to 4 minutes by opening windows or doors, by using Up-
Dux
®
ceiling vents, or a combination of both. The air is always
fresh, not stale, laden with smoke and odors as happens with
refrigerated air conditioning.
