NOTE :
Be sure to set the indoor unit horizontally so as not to
cause malfunction of the float switch (Option) or
leakage of water.
Considering pipe/wire connecting work inside the ceiling after the indoor unit has been hanged, select an installa-
tion place and determine piping direction.
• If the ceiling has been already set, lead refrigerant pipe, drain pipe, connecting wire, switch panel cord, etc. up
to the place where pipe and wire are connected before hanging the main unit.
