INTRODUCTION
Your new air cooler uses a new design for evaporating water to cool air. The low energy use of conventional evaporative air coolers is combined with new water handling methods and materials which help overcome most rust problems
of conventional coolers. Your new cooler requires no pad prewetting and is easy to clean. The compact size and modern appearance allow easy installation.
Please read our instructions before you install and use your new cooler. This will help you obtain the full benefits from
your cooler and will also help you avoid any needless service costs that result from causes we cannot control and cannot cover in our warranty.

work on your cooler. When your hands are inside
the cooler you risk injury if the cooler is accidentally
turned on from inside the home.

4. If you mount the cooler on your home roof remember
these safety tips:
5. Never install or service a cooler during a storm or
high wind conditions. You could be injured or lose or
damage parts.
6. Never wear shoes with slick soles when you work on

INSTALLATION
LOCATING YOUR COOLER
This new design Essick cooler may be installed as a bottom or side air outlet cooler. The cooler must be securely
fastened to a frame or pad mount. A roof kit is available
from Essick.
A duct must be attached to the cooler outlet. The duct
must be the same size as the cooler outlet. Sudden duct
size changes will decrease the output of your cooler.
FIGURE 1
The cooler installation must comply with local codes. If
you are not fully qualified to install a cooler, get professional help.
Figure 1 shows some locations for your cooler. Be sure
the intake louvers are clear of obstructions and are
accessible for removal. Do not locate the cooler near vent
pipes, chimneys, or exhausts where odors or fumes
may be drawn into the house. The two drain holes on the
cooler bottom must be clear to allow overflow or drain
access.
WIRING BOX
The wiring box is inside the cooler cabinet. The electrical
supply must be connected to the cooler power leads
inside the box after the cooler is installed. The wiring box
is factory installed for coolers used in the down air outlet
position.
IF YOU INSTALL THE COOLER IN THE SIDE AIR
OUTLET POSITION THE WIRING BOX MUST BE
MOVED. SEE PAGE 5.
