4. Your cooler will run on either 120V or 240V A.C., single phase,

60 Hz (cycle) current.

5. Motor and pump have a grounded, molded plug and an automatic

thermal overload switch which will shut motor off when it over-
heats. The motor will restart automatically when it cools down.

Evaporative Cooling

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 a swimming pool with the wind blowing, evaporative
cooling makes you feel cool, even though the air may be warm.
The human body itself is cooled primarily by the evaporation of
perspiration.

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.

Evaporative Cooler Manual

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.

Operation

For the best cooling performance, if the pads are dry, pre-wet the pads
by running the pump for a few minutes before starting the blower.

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.

Open Windows To Exhaust Air

An often misunderstood concept of evaporative cooling is the amount
of air that should be exhausted. How much should you open your
windows? The fact is that most people do not open their windows
enough. The following two methods will help you determine the
amount to open your windows.

CFM Method

You should allow an opening of at least 2 square feet (288 square
inches) for each 1000 CFM rating of your unit.

Example:

At 3654

CFM, model 4001 DD with a 1/2 hp motor requires 7.3 square feet
(1052 square inches) of opening (3654/1000 * 2 = 7.3). Multiply
the number of windows by window width in inches and divide this
into the number of square inches required for your size unit. This
will give you the height to open windows. In this example, four 36
inch wide windows should be opened 7.3 inches each.
