Evaporative coolingworkson theprincipleofheatabsorption bymoistureevaporation. Whena swimmer
leavesthewateron awindyday,he feelscool becausethe moistureon his bodyis evaporating a nd
absorbing heat.
Yourevaporative cooler drawsexteriorair into special pads soaked withwater,where the air is cooled by
evaporation,then circulatedinto your home.
Your evaporative cooler makes the best possible use of the evaporative process by metering the flow of
water, distributing it evenly through the filter media, and blowing a steady stream of cooled air into your
home. The air is then channeled through the building and vented out of the home through open
windows, doors or vents.
In _
are the major parts of your cooler that keep this process operating efficiendy. The motor (1)
drives the blower (2) which draws air from outside through the pads (3) saturated with water from the
pump (4) via the water distribution system (5). The float valve (6) and standpipe (7) hold the water In a
reservoir (8) at a constant level.

before attempting
to install,
open, or service your
cooler. If the cooler is
thermostatically
controlled,
the
thermostat
is not to he used as a
disconnect
as it may reset and start
the unit unexpectedly.
Evenwhile routinelyinspecting or servicingthe
inside, the cooler can be accidentallystarted. Keep
children and pets awayfrom the cooler and
electricalsupplywhen you are working on it.
Always use the recommended tools listed in this
manual. Don't attempt to perform any part of the
installationdescribed in thisbook unless you are
fully qualified
to do so. Allelectricalwork must
meet local cedes and must be performed by

Your cooler may he... a horizontal

techniques are shownin thefollowing s ection.
If the cooler you have selected is m be
mountedon the roof of your home,remember
these important roles:
• Never attempt t oinstallorservicea coolerduring

• Never wearshoeswithslicksoleswhenworking
orwalking on a roof When youleastexpectit you
mayend up slipping.
• Never d rainwaterdirectlyon a roof Usea drain
hoseto run waterto the groundortoa rain gutter.
Before attempting to install the cooler, make
sure the following preparations have been
made:
• Assure thatdie mounting surfaceis strong enough
tobearthe weight o fdie coolerwhenin use;
rememberthat w hendie system fillswithwater,the
coolerwillbemuchheavierthan whendry.For
operating weight, s eeaccompanying partslist.
• Make sure you
have
adequate
meansfor
lifdng the
coolerinplace.
• Cheek die electrical s upply to seethatit matohes
the requirements s hownonthe motornameplate.
• Makesure themounting surface i s levelin all
directions.
• Makesure anyductwork a nd electrical needs
comply withlocal,state,county and federalcodes.
• Makesure cooleris secureto the standor legkit
andthatis secureto the roof.
If the cooler is to be mounted on the roof,construct
a suitable roof stand to support the entire weightof
the unit. Aroof jack should not be used tosupport
any weightof the unit. We recommend a #785 leg ldt
to support the unit and to secure it to the roof. Place
the cooler over the roof jack and position so that it
is level.Carefullyseal die space betweenthe roof
jack and bottom of cooler withcaulking compound,
silicone, asphalt or industrial sealing tape to prevent
air leakage. Then carefullyseal the roof jack to roof
withasphalt or caulkingcompoundto prevent air
leakagefrom cooler or rainwater from leaking into
roof.
