ADJUSTING THE AIR DEFLECTORS
1
Adjustment of the conditioned air in the upward
and downward directions.
The horizontal air deflector is automatically set to
the proper angle suitable for each operation. The
deflector can be swung up and down continuously
and also set to the desired angle using the "
(AUTO SWING)" button.
• If the " (AUTO SWING)" button is
pressed once, the horizontal air deflector
swings up and down. If the button is
pressed again, the deflector stops in its
current position.
• Use the horizontal air deflector within
the adjusting range shown in the right
figure.
• When the " (AUTO SWING)" button is
pressed while the operation is stopped,
the horizontal air deflector moves and
stops at the position where the air outlet
closes.
• When the auto swing operation is
performed, if the horizontal air deflector
is moved manually, the swinging range
may drift. However, it will return to the
original operation range after a short
time.

Adjustment of the conditioned air to the left and
right.
Hold the vertical air deflector as shown in the figure
and adjust the conditioned air to the left and right.
CAUTION
• When operating the unit in cooling operation with the air deflector facing down and moving automatically
for a long period of time, water will be condensed on the air deflector and drips down occasionally. This
will wet your furniture.
