OPERATING INSTRUCTIONS
Airflow direction control
Do not operate the air conditioner for long periods with
the air flow direction set downward in cooling or
dehumidifying mode. Otherwise, condensation may
occur on the surface of the horizontal louver causing
moisture to drop on to the floor or on furnishings.
Do not move the horizontal louver manually unless it is
necessary.Always use the remote controller.
When the air conditioner is started immediately after it
was stopped, the horizontal louver might not move for
approximately 10 seconds.
Open angle of the horizontal louver should not be set
too small, as COOLING or HEATING performance may
be impaired due to too restricted air flow area.
Do not operate unit with horizontal louver in closed
position.
When the air conditioner is connected to power (initial
power), the horizontal louver may generate a sound for
10 seconds, this is a normal operation.
