Mitsubishi SEZ-NL Low-static Horizontal-ducted Indoor Unit service details

SEZ Horizontal-ducted Indoor Units are designed to heat and cool one or two rooms through a short duct run. These units may be mounted in the attic, hidden in the ceiling or beneath the floor, or concealed behind a bulkhead. Only the intake-air grille and outlet vents are visible when using the SEZ ceiling-concealed indoor unit. The compact design requires minimal space and installs in buildings with lowered ceilings or attics.
