carefully before installing,
operating or servicing your
evaporative cooler.
ShFETY
Caution:
Disconnect all
electrical power
to the cooler
before attempting
to install, open, or service your
cooler. If the cooler is
thermostatically controlled, the
thermostat is not to be used as a
disconnect as it may reset and start
the unit unexpectedly.
Evenwhileroutinelyinspectingor servicingthe

Toinstallcooler cabinet, the followingtools are
required:
• wood Strip
• 5/32" bex keyAllenwrench
• Pliers
• Adjustablewrenches
• Tubingcutter
• Screwdrivers
Your cooler may be... a horizontal
discharge, a down discharge, or a windowmodel.
Horizontal discharge units are designed for
installationon the side ofa building,on a flator
pitchedroof, or on a slab at ground level.Down
discharge coolers are designedfor flator pitched
roofs. Window models attach easilyto window
apertures or throughthe wall.Variousinstallation
techniquesare shownin thefollowingsection.
If the cooler you have selected is to be
mounted on the roof of your home, remember
these important rules:
• Neverattempt to install or servicea cooler during
astorm or in high windconditions. Besiderisking
loss or damage to parts, youcould be risking
substantialinjury
• Neverwear shoes withslick soles whenworking
or walkingon a roof.Whenyou leastexpectit you
mayend up slipping.
• Neverdrain water directlyon a roof. Usea drain
hose to runwater tothe ground or toa rain gutter.
Beforeattemptingtoinstallthecooler,make
sure thefollowingpreparationshavebeen
made:
• Assurethatthe mounting surface is strong enough
to bearthe weightof thecooler when in use;
remember thatwhen the systemfillswithwater,the
cooler will be much heavier thanwhen dry.For
operating weight,see accompanyingparts list.
• Makesure you haveadequate means for liftingthe
cooler in place.
• Checkthe electrical supplyto see that it matches
therequirements shownon themotor name plate.
• Makesure the mountingsurface is levelin all
directions.
• Makesure anyductwork and electrical needs
complywithlocal, state,countyand federal codes.
• Makesure cooler is secure to the standor legkit
and that is secure to the roof.

Caution:
Disconnect all
electrical power to the
cooler before attempting to
install, open, or service
your cooler. If tbe cooler is
thermostatically controlled,
the tbennostat is not to be
used as a disconnect as it
may reset and start the unit
unexpectedly.
Note: Do Not Undercoat The
Water Reservoir
Yourcooler's water reservoir is finished
with a PolybondTuapphance-type finish.
It is so hard that asphalt-type cooler
undercoating will not stick to it.
Undercoat will break free and clog pump
and water disMbutor.
Do not use cooler cleaners, cooler
treatments, or other additives in this
evaporative cooler. The use of any of
these products will void your
warrantyand may impair the life of
your evaporative cooler.
Drainingand Touch-Up
Cleanthecoolercabinet(withpoweroffand

1. Connecta drain hose to the drain fittingto the

2. Removestandpipefrom the drain fittingand
allowwater to drain(never drain wateronto a
roof,make sure drain hose is long enough to
reacha gutteror over edge of house).
3. Cleanreservoir.

Add-OnCoolers
Coolers come in a,,vide arrayof sizes,horsepower, and
capacities suitable for patio, garage, guestroom, mid so
forth.More thanone cooler in a singlehome improves the
cooling effectivenessof theentire system. Owners of
refrigerated air conditioning have found that the addition
ofan evaporativecooler rosilyreduces theirelectric bills.
insulation
Onceyourcooler fozees cooled air into your home and
pushes the hot air out, good insulation around your
duclwork willkeep theair as cool as possible. Whole
house insulation will prevent heat from seeping in and will
improve cooling comfort.
MniB-SpeedMotor
The coolingrate can be controlled by increasing and
reducing the amount ofcooled air blown intoyour home.
Two-speedmotors allowyou touse higher speeds during
the honest part of the day, lower speeds for milder
temperatures.
Bleed-off
Bleed-offcomponents are included _th each cooler and
should be installed as instructed in this manual.
AtticVents
Byexhausting cool air throughtheattic, you can reduce
thetemperatureofthishot spot and makeyour home
more comfortable. Itis imporiant to remember toprovide
adequate exhaust in the area. Again,provide 2 square feet
