1. Raisethesashtotheindicatednormaloperationalheight(READYstate).
2. Turnonthelampbypressingthelampbutton.
3. TurnonthefanbypressingtheFANbutton.InputtheFanPINifasked(default:0001).Thiswillstart

3.3OperatingtheDuctlessFumeHood
3.3.1WorkingintheHood
• Checkthelabelontheductlessfumehoodtoseewhatchemicalsthehoodisintendedfor–andonly
usethehoodforanyprocedureinvolvingsuchchemicals.
• Ensuretheexhaustisoperatingbeforecommencingwork.
• Afteralltheapparatuses/itemshavebeenarranged,allowtheblowerto
runforanother3minutesin
ordertopurgeworkzoneofcontaminants.
• Minimizeroomactivitysincetheseexternalairflowdisturbancesmayadverselyaffectthehood’s
internalairflow,impairingthecontainmentcapabilitiesofthefumehood.
• Keepyourheadoutsideofthehood.
• Workasfarinto
thehoodaspossibleandwithslow,deliberatemovements,tominimizeairflow
disturbances.
• Workwiththesashasfullyloweredaspossible,utilizingthesashasanaturalbarrier.
• Donotusethishoodasastoragearea.Itemscanblockairflowandinterferewithcontainment.
• Ifperformance
issuspected,oranairflowalarmistriggered(ifinstalled),terminateusage,closethe
sashcompletely,andceasework.
• Donotletorganicchemicalsevaporateinthehood–useaproperwastebottle.Donotleave
uncappedbottlesofchemicalsorwasteinahood.
• Certifythis
hoodannuallytoverifyairflowvelocity,smokepatternsandcontainment.
• Performroutinemaintenanceinaccordancewiththemanufacturer’sinstructions.
