Duct System
Air can be delivered over a distance to individual rooms or areas by
means of a duct system. The duct system, which is tailored to fit the
building, should be designed, fabricated and installed by a competent
HVAC sheet metal contractor, preferably while building is under
construction.
Air Exhausting
Evaporative air coolers will function correctly only if there is a way for
the cooled air to exit the building. Proper location of exhaust openings
is important as they guide flow of air through areas where cooling is
desired; they should be at a point most distant from cooled air inlet and
permit free movement of air out of the area being cooled. Using
standard CFM ratings, a general method for determining how much to
allow for exhaust openings (vents, doors or windows, etc) for proper
air exhausting is 2 square feet of unrestricted opening per 1,000 CFM.
Unit Assembly
The blower and media module(s) are shipped separately. Upon
installation, bolt the modules together using the provided brackets
and mounting hardware (see figure 1). Be sure to install star washers
where indicated to provide ground continuity between the modules. To
maximize cooling performance, apply foam gasket tape along the
sides, top and bottom of the media module(s) where the media and
blower sections join.
Hoisting
With the use of a spreader bar, the brackets that bolt the modules
together also provide a convenient means for lifting the cooler into
place. Assure that the hoisting equipment is of adequate capacity to
safely lift unit into place. Attach lifting means as shown in figure 2.
CAUTION:

INTRODUCTION
Read This Manual Completely Before Installing Your Industrial
/ Commercial Evaporative Cooler.
Your evaporative cooler is a well crafted unit built using decades of
constant engineering research and product development to create an
efficient, reliable and economically operating device. Your air cooler
was thoroughly tested and inspected before leaving the factory; with
regular inspection and maintenance, it will serve as the heart of your
building's overall air-cooling and distribution system for many years.
This manual is your guide to proper installation procedures along with
information about reasonable care and maintenance that will ensure
safe, economical and trouble free cooling. Failure to follow these
instructions may damage your cooler, impair its operation, create the
potential for serious personal injury and/or void the warranty.
Read it
carefully.
Don't attempt to perform any part of the installation described in this
manual unless you are
fully qualified
to do so.
CAUTION:
All mechanical, plumbing and electrical
installations must comply with local and national building
and safety codes, and must be performed by qualified
personnel only.
Before attempting to install the cooler, confirm that the following
preparations have been made:
Verify that the supporting
surface is strong enough to
bear the weight of the
c o o l e r w h e n i n u s e ;
remember that when the
system fills with water, the
cooler will be much heavier
than when dry.
Make sure you have adequate resources (cranes, safety
harnesses, rigging, etc.) for lifting the cooler into place.
Check the electric power supply to see that it matches the
requirements shown on the model and motor nameplates.
Verify that the supporting surface is level in all directions; this is
necessary to ensure proper distribution of water to the pads and
maximizing cooling performance.
Confirm that any planned ductwork and electrical supply
installation needs comply with local and national codes.
Location
Install coolers in a location where only fresh outside air can enter the
cooling system. Avoid installing units in closed-in areas, such as an
attic or storeroom, which restricts free air movement around and into
the cooler, or near vent pipes, kitchen exhaust, etc.; as obnoxious
odors or fumes may be drawn into unit.
NOTE: When coolers are installed within the jurisdiction of the City of
Los Angeles (C.O.L.A.) building codes, they can only be installed on
the outside of buildings.
It is also required that any electrical
components (motors, pumps, motor starters, etc) used in a C.O.L.A.
installation shall be either:
1. Currently listed for its intended use as part of the cooling system
equipment by a City of Los Angeles recognized electrical testing
laboratory (i.e., UL, ETL, CSA, etc.) or,
2. Currently approved for general use by the City of Los Angeles -
Electrical Testing Laboratory.
