TEMPERATUREPROBEPLACEMENT:Idealtemperatureplacementisafunctionofracktype,appliance
type,airflowandspecificappliancelocationand density.Asageneralruletemperatureprobesare
placedontheintake(cool)orfrontsideoftherack.Thisistomonitorthetemperatureoftheinputair

recommendedtomonitorboththeinput(front)andoutput(rear)airflow.
