vent weld spatter and other foreign materials from entering

water can leak.)

(3) Check the level of the unit. (Refer to Fig. 8)
(4) Remove the washer clamp (9) used for preventing the
washer for hanger bracket (11) from dropping and tighten

CAUTION
• Install the indoor unit leveled.
If the indoor unit is inclined and the drain piping side gets
high, it may cause malfunction of float switch and result in
water leakage.
• Attach nuts on the upper and lower side of hanger
bracket.
If there is no upper nut and the lower nut is over-tightened,
the hanger bracket and the top plate will deform and cause
abnormal sound.
• Do not insert materials other than that specified into
the clearance between the hanger bracket and the
washer for hanger bracket (11).
Unless the washers are properly attached, the suspen-
sion bolts may come off from the hanger bracket.
WARNING
The indoor unit must be securely installed on a
place that can withstand the weight.
If the strength is insufficient, the indoor unit may fall
down and cause injuries.
