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 using the high speed setting, turn the dip switch SW9-4 on the
indoor PCB to the ON position.
(When setting from the remote controller, select "Hi CEILNG 1")
