Evaporative Air Coolers

70932

Rev. 6/02

Evaporative Cooling
Evaporative cooling uses the principle of evaporation to lower the air temperature. Hot, dry air is passed through wetted
filters and is converted to refreshingly cooled air. Essick Coolers make the best use of the evaporative process by
controlling the flow of water, spreading the water evenly over the filters, and keeping a steady stream of cooled air
entering your home. It is exhausted out open windows or doors, carrying heat, smoke and odors along with it. Essick
evaporative coolers are 80% less costly to operate than refrigerated air conditioners.

Cautions: To prevent harm to yourself and others, and to avoid damage to your cooler, PLEASE follow these guidelines.

SAFETY GUIDE LINES & CAUTIONS

When Installing When Operating When Servicing

Make sure that unit is installed on a sound
structure that will support the full operating
weight of the cooler. See page 3.

Before attempting to transport the cooler to the
mounting location, plan a safe way to move the
cooler and remove the louvers to reduce weight.

Do Not connect power to cooler before
installation is complete.

When servicing or installing, always wear gloves,
protective eyewear, and other applicable safety
gear. Never wear slippery-soled shoes when
working on a roof.

Make sure that circuit cooler is wired into is
equipped with a (slow blow) breaker large
enough to support the full amperage of the
cooler.
To reduce the risk of fire or electrical shock, DO
NOT use this fan with any Solid-state speed
control device.
This cooler is equipped with an automatic
thermally protected motor. If it shuts off on its
own for any reason, it can restart without
warning.

Never use a cooler without connecting it to a
duct system or without a sturdy mesh guard over
the outlet.

Always shutoff power to the cooler, at the
breaker, before attempting service of any
kind. If not, it can be turned on from inside
the house and start unexpectedly.
Never drain cooler water onto your roof.
Water residue may cause you to slip or may
stain your roof.
If the motor shuts off because of thermal
overload, check into the problem
immediately. If allowed to continue,
permanent damage will occur.

Never install or service a cooler during a
storm or high wind conditions.

Mounting Requirements

1. Prepare duct to fit model used. See chart below for discharge opening sizes of different models.

2. Assemble all tools and materials needed for installation.

3. Cut opening in roof or wall to fit duct (see # 1). Box in opening and reinforce any cut roof joists or wall studs.

4. Install duct and secure to boxed frame. The duct will fit inside the cooler opening. The duct length from roof to bottom
of cooler should be a minimum of 4” at the closest point, so there is access to the water drain. When installing cooler,
face the drain side toward the downhill side of the duct.

5. Install flashing and seal the duct to prevent water entry.

6. Measure and layout mounting location. A good quality roof stand or cooler pad should be used to mount your cooler.

7. Mount cooler to stand or pad. Cooler must be level front to back and side to side.

8. Be sure to securely fasten all four corners of cooler to stand or pad.

9. Caulk duct to the cooler. Ensure roof or wall opening is sealed well.

Duct Work
The most important principle in duct construction is to keep it simple. Complex duct work is expensive. In attics, long
duct work will reduce the amount of cooling your cooler has produced. The most simple and popular system is to run a
straight duct either down from the roof (roof mount) or through a wall into a central hallway. Air is then pulled to other
rooms by means of open windows.

Remember, an evaporative cooler puts out a lot of air, with most applications
exchanging the air in the house every two minutes.

On this page is a simple duct system. The duct itself is a flexible material that can be
easily adapted to any job. Flexible duct is not necessarily good for use with coolers

because the pipe is restrictive, but it is very easy to use. It is expandable and can be
easily routed. It can be cut with scissors or a knife and wire snips. It is easily connected
to existing duct work or directly to a ceiling diffuser.

Remember: the duct work must be the same size or larger than the cooler
discharge. If not the airflow will be restricted, resulting in poor cooling. It is
recommended to oversize flex duct and install a good transition in round duct.
