Notes(1) 1 spot closing: Round duct flange at center is removed and shield with a
special panel (option).
(2) Standard: ø200 duct are installed at all blowout holes.
(3) Square duct: All round ducts are removed and replaced with special
square duct flanges (option).
(4) When setting from the remote controller, select "Hi CEILNG 1"
