Here is the solution. (Unit is operating normally.)
I Clean the filter. (Airflow is reduced when the filter is dirty or clogged.)
I Check the temperature adjustment and adjust the set temperature.
I Make sure that there is plenty of space around the outdoor unit. Is the
indoor unit air intake or outlet blocked?
I Has a door or window been left open?
I Warm air does not blow until the indoor unit has sufficiently warmed up.
I When the outdoor temperature is low and the humidity is high, frost may
form on the outdoor unit. If this occurs, the outdoor unit performs a de-
frosting operation. Normal operation should begin after approximately
10 minutes.
I During cooling mode, the vanes automatically move to the horizontal
(down) position after 1 hour when the down (horizontal) airflow direction
is selected. This is to prevent water from forming and dripping from the
vanes.
I During heating mode, the vanes automatically move to the horizontal
airflow direction when the airflow temperature is low or during defrosting
mode.
I When the airflow direction is changed, the vanes move to the set posi-
tion after detecting the base position.
I These sounds can be heard when refrigerant is flowing in the air condi-
tioner or when the refrigerant flow is changing.
I These sounds can be heard when parts rub against each due to expan-
sion and contraction from temperature changes.
I The indoor unit draws in air that contains gases produced from the walls,
carpeting, and furniture as well as odors trapped in clothing, and then
blows this air back into the room.
I If the indoor temperature and the humidity are high, this condition may
occur when operation starts.
I During defrosting mode, cool airflow may blow down and appear like a
mist.
I During cooling mode, water may form and drip from the cool pipes and
joints.
I During heating mode, water may form and drip from the heat exchanger.
I During defrosting mode, water on the heat exchanger evaporates and
water vapor may be emitted.
I Turn on the power switch. " " will appear in the remote controller display.
I During central control, "

air conditioner operation cannot be started or stopped using the remote
controller.
I Wait approximately three minutes.
