INTRODUCTION

Read This Manual Completely Before Installing
Your Industrial Fan 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 economical to operate device. Your fan 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 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 cooler when in use; 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 into the pad frame
troughs, maximizing cooling performance.
Confirm that any planned ductwork and electrical supply
installation needs comply with local and national codes.
Location
Industrial Fan evaporative air coolers are not designed to be
connected to a duct distribution system, they are designed for
connection to a straight drop duct and the use of a low restriction
diffuser for distribution of cooled air throughout an area. When these
fan coolers are used to cool large areas, such as factories,
warehouses or large covered areas, divide the total area and
strategically locate units of proper capacity in each area
Install coolers in a location where only fresh outside air can enter the
cooling system. Do not install coolers 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.
2 Industrial Fan Evaporative Cooler - Use and Care Manual
NOTE: When coolers are installed within the jurisdiction of the City of
Los Angeles (C.O.L.A.) Building codes, it is 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.
Duct System
This fan cooler is designed for use in non-ducted applications, where
only a short vertical drop duct/plenum with or without a simple air
diffuser at the lower (discharge) opening. If the lowest discharge point
of the short duct is less than 10 feet above the floor, a guard or grille is
required. This short duct, 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 coolers will function correctly only if there is a way for the
cooled air to exit the building. Windows, suitable vents or dampers,
doors or other exhaust openings at a point most distant from cooled air
inlet should be open to permit free movement of air out of the area
.
being cooled, and to avoid building up excessive pressure inside the
space. Proper location of these exhaust openings are important as
they guide flow of air through areas where cooling is desired.
To utilize the maximum capacity of your cooler and to help keep
insects, dust, dirt, etc out of the cooled space, the building/space
should be maintained at a slightly positive air pressure (airflow into the
building slightly more than leaving airflow). A general method for
determining how much exhaust opening (vents, doors or windows,
etc) is required for proper air exhausting is: 2 square feet of
unrestricted opening per 1,000 CFM, using the standard CFM ratings
listed for your cooler.
