Air flow selection
• Make air flow selection according to what suits you.
When setting the air flow selection switch to .
• Air conditioner automatically decides the appropriate blowing pattern depending on the operating
mode/situation.
• During Dry mode, so that cold air does not come into direct contact with people, air is blown
upper air outlet.
When setting the air outlet selection switch to .
• Regardless of the operating mode or situation, air blows from the upper air outlet.
• Use this switch when you do not want air coming out of the lower air outlet. (While sleeping etc.)
CAUTION
Operating mode Situation Blowing pattern
COOL mode
• When the room has become fully
cool, or when one hour has
passed since turning on the air
conditioner.
• So that air does not come into
direct contact with people, air is
blown upper air outlet, room tem-
perature is equalized.
• At start of operation or other
times when the room is not fully
cooled.
• Air is blown from the upper and
lower air outlets for high speed
cooling during COOL mode, and
for filling the room with warm air
during HEAT mode.
HEAT mode
• At times other than below.
(Normal time.)
• At start or when air temperature
is low.
• So that air does not come into
direct contact with people. Air is
blown upper air outlet.
• Do not try to adjust the flap by hand.
• When adjusting by hand, the mechanism may not operate properly or condensation may drip
from air outlets.
