PMI AEROCOOL Trophy Serie Manual De Uso Y Cuidado página 2

INTRODUCTION
Your Trophy evaporative air cooler was thoroughly tested and
inspected before leaving the factory. 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.
Installation normally involves the connection of the blower opening to
a duct system or to a short duct with a ceiling diffuser.
installation in an existing building, modifications may be necessary. If
installation is being done by someone other than a professional HVAC
contractor, it is suggested that the installation be thoroughly discussed
with a professional person familiar with cooler installation.
attempt to perform any part of the installation described in this manual
unless you are fully qualified to do so.
Carefully read the contents of this manual before beginning the
installation process.
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.
NOTE - References in this manual to local or national codes means
that those items must comply with applicable installation codes as
specified by the building code authority having jurisdiction at the
installation location. It is the installer's duty to comply with all building
code requirements.
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 for lifting the cooler.
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,
maximizing cooling performance.
Confirm that any planned ductwork and electrical supply installation
needs comply with local and national codes.

Location
Your cooler may be a down (TD), horizontal (TH) or up (TUP)
discharge model. Down discharge coolers are designed for
installation on either flat or pitched roofs (see Fig. 1). Horizontal
discharge coolers are designed for installation on the side of a building
or, using a 90-degree transition duct, on a flat or pitched roof (see Fig.
2). Up discharge coolers are designed for ground level installation,
mounted on a slab (see Fig 3). Evaporative air-cooling systems
(down, side or up discharge) can be connected to a duct distribution
system with outlet registers for each area to be cooled.
For an
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

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.
Air Exhausting / Maximum Cooling
Evaporative air coolers will function correctly only if there is a way for
the cooled air to exit the building. Windows, vents, 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 exhaust openings is important as they guide flow of air
through areas where cooling is desired.
Since coolers function best when there is plenty of exhaust air, you
can leave doors or windows open so your house can breathe.
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 going into the
building should be slightly more than the air that is leaving).
How much should you open your windows? You should open your
windows until the air pressure inside the house is nearly balanced
with the air outside. One method used to determine when the air is
reasonably balanced is to place a tissue paper against the screen
in the window furthest from the cooler and adjust the opening of the
other windows in the house until the tissue paper stays lightly on the
screen. This is usually about 2 square feet of opening per 1000 cfm
of air produced by the cooler. You can adjust different windows in
the house to direct the most airflow to the areas that are occupied
during different times of the day or night (example: living room
windows during the daytime, bedroom windows at night.)
To eliminate a rush of warm air when starting the cooler be sure to
turn on the pump for a few minutes to completely wet out the pads
before turning the blower on.
