* Measurement taken 6.5' (2 m) in front of SDU cabinet.
** For visible vapor to be absorbed completely within the SDU-I unit before being
discharged as humidified air, room air must be 45% RH or less. Trying to maintain
greater than 45% RH will cause visible vapor and potential for moisture collection on
the discharge grille.
