Getting the most
from your cooler
Your evaporative cooler is a finely crafted, eco-
nomically operating unit built on decades of
know-how and reseamh. It serves as the head of
an overall air cooling and moving system for your
home. But there are a number of ways you can
maximize the comfort, efficiency, economy and
convenience of your total cooling system.
Maintenance
Regular maintenance as recommended in this
manual, is essential for cooling comfort, extend-
ing the life of your cooler, and avoiding unneces-
se_/pads replacements. Start-up and shutdown
servicing should never be ovedooked.
Add-On
Coolers
Coolers come in a wide array of sizes, horse-
power, and capacities, suitable for patio, garage,
guestroom, and so fodh, More than one cooler in
a single home improves the cooling effective-
ness of the system. Owners of refrigerated air
conditioning have found that the addition of an
evaporative cooler vastly reduces their electric
bills.
Insulation
Once your cooler forces cooled air into your
home and pushes the hot air out, good insulation
around your ductwork will keep the air as cool as
possible. Whola-house insulation will prevent
heat from seeping in and will also improve cool-
ing comfort.
Multi-Speed
Motor
The cooling rate can be controlled by increasing
and reducing the amount of cooled air blown into
your home. Two-speed motors allow you to use
higher speeds during the hottest pad of the day,
lower speeds for milder temperatures.
Attic Vents
By exhausting cool air through the attic, you can
reduce the temperature of this hotspot and make
your home more comfodable.
Thermostat
Control
The addition of automatic control makes your
system convenient and efficient. We recommend
the MasterStat
TM,
Model CC1000A, Universal
Evaporative Cooler Thermostat and Control Kit.
