CA U TION ------------------------
• Install the indoor unit leveled.
If the indoor unit is inclined and the drain piping side gets high, it may cause malfunction of a float
switch and results in water leakage.
• Attach nuts on the upper and lower side of hanger.
If there is no upper nut and the lower nut is over-tightened, the hanger and the top plate will deform
and cause abnormal sound.
• Do not insert materials other than that specified into the clearance between the hanger and
the washer for hanger (3).
Unless the washers are properly attached, the hanging bolts may come off from the hanger.
