CHARACTERISTICS OF THE COOLING OPERATION
• If the COOLING OPERATION is used when the indoor temperature is low, frost forms on the heat
exchanger of the indoor unit. This can decrease the cooling capacity. In this case, the air conditioner
automatically switches to the DEFROST OPERATION for a while. During the DEFROST OPERATION,
the low fan speed is used to prevent the discharge of melt water. (The remote controller displays the fan
speed that is set.)
• When the outdoor temperature is high, it takes some time until the indoor temperature reaches the
set temperature.

• Prevent direct sunlight from the window by using curtains or blinds during the COO LING OPERATION.
• Keep doors and windows closed. If the doors and windows remain open, room air will flow out and
decrease the effect of cooling and heating.
• Never place objects near the air inlet and the air outlet of the air conditioner. It may decrease the effect or
stop the operation.
• Set the airflow of the air discharge grille horizontally not to obstruct the wind. Otherwise, the wind will not
come out and a failure may result.
• Adjust the room temperature properly for a comfortable environment. Avoid excessive heating or
cooling.
• Operating the indoor unit with stained air filter may decrease capacity or cause malfunction.
• Install T
V
's, radios and stereos 1 m ar more away from the indoor unit and remote controller. Images may
become fuzzy and noise may be generated.
Turn off the power circuit breaker when it is not in use for a long period. When the power circuit breaker is
turned on, small amount of power is consumed even if the air conditioner is not in operation.( *1)
Turn off the power circuit breaker for saving energy. When re
-
operating, turn on the power circuit breaker 6
hours before operation for smooth running.(*2)
*1 The consumed power while the outdoor unit is not in operation depends on the model.
*2 The setting before the power circuit breaker is cut off is stored. (The timer setting is cleared.)
Use the TIMER OPERATION effectively.
It takes some time until the indoor temperature reaches the set temperature. It is advisable to start
operation in advance using the TIMER OPERATION.
