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 or a combination of both.  The air is always fresh, not stale, laden 
with smoke and odors as happens with refrigerated air conditioning.

To eliminate the delivery of hot air when starting the cooler, start the 
pump only for the fi rst few minutes, then turn on the blower motor.

These coolers may be used without water for ventilation purposes.  When 
outside air is cool (for example, at night) or when humidity is high the 
water pump can be turned off.

A cooler can also be installed with a thermostat and attic exhaust dampers 
to provide completely automatic operation.
