1_ Read these instructions

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.

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 flat or

pitchedroof, or on a slab at ground level.Down

discharge coolers are designedfor flator pitched

roofs. Window models attach easilytowindow

apertures or throughthewall.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 service a cooler during

astorm or in high windconditions. Besiderisking

loss or damage to parts, youcouldbe risking

substantialinjury

• Neverwear shoes withslick soles whenworking

or walkingon a roof.Whenyou leastexpectit you

mayend up slipping.

• Neverdrain waterdirectlyon a roof. Usea drain

hose to runwater to the ground or toa rain gutter.

Beforeattemptingtoinstallthecooler,make

sure thefollowingpreparationshavebeen

made:

• Assurethatthe mountingsurface is strong enough

to bearthe weightof the cooler when in use;

remember thatwhen the systemfillswithwater,the

cooler will be much heavier thanwhen dry.For

operating weight,see accompanyingparts list.

• Makesure you haveadequate meansfor liftingthe

cooler in place.

• Checktheelectrical supplyto see that it matches

therequirements shownon the motor 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 leg kit

andthat is secure tothe 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

bottomof the reservoir.

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 ofhouse).

3. Cleanreservoir.

The hardness, adhesion and smoothnessofthe

Add-OnCoolers

Coolerscome 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 intoyour 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-offcomponents are included _th each cooler and

should be installed as instructed in this manual.

Byexhausting cool air throughtheattic, you can reduce
