Heavynegativepressurewherethecondensatefromtheplateheatexchangeriscollectedinthedriptray
allowsairtoflowthroughthedrainagepipeintotheunitandpreventscondensatewaterfromflowingout
oftheunitthroughthedrainagepipe.Awatertrapwithsufficientclosinglevelofthe
waterisextremely
necessarytoensurethatcondensatewaterflowsoutoftheunit.Thepipediameterofthewatertrapand
sewagesystemmustbeidenticaltothepipediameterofthedrainageoutletfromthetray. 
Theclosinglevelofthewatertrapmustbeestimatedcorrectlyto
ensuresafeescapeofthewater(seethe
illustrationandestimatetheminimumclosinglevelaccordingtothetable).
Awatertrapisoptionalandinstallationofthewatertrapisnotincluded.
