CAUTION
•
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 malfunction and create un-
wanted noise.
• Do not insert materials other than those 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.
WARNING
The indoor unit must be securely installed on a
place that can withstand the mass.
If the strength is insufficient, the indoor unit may fall
down and cause injuries.
