PORT-A-COOL Hazardous Location Units*

I. INTRODUCTION

The PORT-A-COOL unit is a fully self-contained, portable, high efficiencyevaporative cooler that is proudly made in America

at our factory located in Center, Texas.

A. What is Evaporative Cooling?

Whentryingtounderstandevaporativecooling,itmaybebesttothinkofairasbeinglikeasponge,in

thatregard,airhasanabilitytoabsorbmoisturethatitcomesincontactwith.Theamountofmoisturethattheairwillabsorbdependsonthestateoftheair,orspecifically,howmuchmoisturetheairalreadycontainsand

thetemperatureoftheair.Iftheairiswarmandcontainsonlyasmallamountofmoisture,itwillmorereadilyabsorbmoisture.Asaircools,itsvolumedecreases,andwithit,itsabilitytoabsorbmoisturedecreases.

Thetermrelativehumiditydescribesthequantityofwaterintheairinrelationtoitstotalcapacity.Anyvolumeofairatanygiventemperaturehasanabilitytoholdacertainquantityofmoisture.Iftheaircon-

tains20%ofitstotalcapacitytoholdmoisture,therelativehumidityissaidtobe20%.Whereas,ahumidityof100%indicatesthattheairatthistemperatureandpressureisholdingallthemoistureitcan.Iftheairhasless

Howiscoolingproduced?Inordertoevaporatewater,heat(energy)isrequired.Infact,theevapora-

tionofonegallonofwaterrequiresalmost8,700BTUs.Wheredoesthisheatcomefrom?Theheatcomesfromwhateverthewaterisincontactwithasitevaporates.Thiscouldbeahotsidewalk,yourbody,atree,orfrom

Theextenttowhichrelativehumiditydecreasesthroughthedaycanbeaffectedbylocalweathersys-temsandproximitytolargebodiesofwater.Ifanincreaseintemperatureaccompaniedbyaweathersystem

containingmoisturemovesin,thenthedropinhumiditywillnotbeasgreat.Nevertheless,thefactremainsthatrelativehumiditydoesdropasairtemperatureincreases.Infact,forevery20Friseintemperature,themois-

ture-holdingabilityofairdoubles.Forinstance,ifthetemperatureoftheairwas70Fandtherelativehumiditywas100%at5a.m.,andthetemperatureincreasedto90Fatnoon,themoistureholdingabilityoftheairwoulddouble.

Asaresult,theairwouldnowbeholdingonlyhalfofthemoistureitiscapableofholding,andtherela-

tivehumidityoftheairwoulddropto50%.

Sinceanyevaporativecoolingdevicemustevaporatewatertoachievecooling,morewatervaporisput

II. OPERATING PROCEDURES

A. Placement of the PORT-A-COOL@ unit.

PORT-A-COOL@ units should be used in well-ventilated areas only.

2)AirPattern-ThecoolairdischargedfromthePORT-A-COOL unit shouldhaveaclear areatocirculatein,asfreeofobstructionaspossible.

3)Ventilation(Exhaust)-Thereshouldbeadefinedplaceinwhichtheairfromthe

Itmaybedesirabletoraisethe PORT-A-COOL unitaboveanylowobstructionsinordertoincreasetheoverall coverage.When raising the height of the PORT-A-COOL unit, insure that theplatformconstructed forholdingthePORT-A-COOL unitisstable,wellconstructed,andwillnotallowthe PORT-A-COOL unittotipover.ThePORT-A-COOL unitMUSTbelevelonitsbase.Whensupportingwithaplatform,allowforthefullweightofafunctioningPORT-A-COOL unitbyincludingtheweightofthewaterbothinthesumptankandtheaddedweightofthewater-saturatedcoolingpads.Thetotalweightcouldbeinexcessof500lbs.(227kg.).

WhenthePORT-A-COOL unitisplacednearawallorotherobstruction,itisrecommendedthatadis-tanceofatleast3feetfromthewallorobstructiontothefaceofthecoolingpadsismaintained.Thisallowsthe

ingonyoursupplyvalveandallowingthe PORT-A-COOL unitsumptanktofillwith water.Oncethesumptankisfull,thefloatvalvewillshutoffthesupplyflow.(50PSImaximuminletpressure.)

C. Starting the pump and adjusting the water flow.

CAUTION -DO NOT RUN PUMP WHEN SUMP IS DRY.

Oncethesumptankisfull,thepumpmaybeturnedonbymovingthepumpswitchtotheONposition.Afterthe

pumpisturnedon,thebluepumpprimevalve(locatedabove&totheleftofthespraybaradjustment) should beopened for 3 seconds and then closed.Thiswillprimetheinternalbrasspump.

Adjust the water flow over the cooling pads where the pads appear to

have a few dry streaks in them.
