 Usethedual7‐segmentLED
displayadjacenttothedip
switchestoobtainthe
approximateairflowquantity.
 Theairflowquantityisdisplayed
asanumberonthedisplay,
roundedtothenearest100CFM.
 Thedisplayalternatesairflow
deliveryindicationandthe
operatingmodeindication.
 Iftheairflowbeingdeliver
edis
1375,CFM,theLEDdisplaywill
indicatea“14.”(for1400CFM)

 Determinethetonnageofthe
coolingsysteminstalledwiththe
furnace.
 Ifthecoolingcapacityisthe
BTU/hr,divideitby12,000to
convertthecapacitytotons.
 So,ifyourcoolingcapacity
requirementis
42,000BTU/hr
then42,000÷ 12,000=
3.5tons.
 Determinetheproperairflowfor
thecoolingsystem.
 Mo
s
tcoolingsystemsare
designedtoworkwithairflows
between350and450CFMper
ton.
 3.5tonsX400CFM=1400CFM.
