Hanging down of indoor unit
Refer to installation figures of hanging material and hanging bolt.
• Adjustment of hanging bolt length and nut position
Adjust hanging bolt length and nut position as shown in the figure before hanging
down the indoor unit.
NOTE
Be sure to set the indoor unit horizontally so as not to cause malfunction of the float
switch or leakage of water.
Considering pipe/wire connecting work inside the ceiling after the indoor unit has been hanged, select an installation 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.
REQUIREMENT
The hanging bolt pitch on longitudinal direction is not divided at center with the ceiling opening size. Therefore, check the
relational position in the following figure.
