5. OPERATION PROCEDURE
Read the installation manual attached to the outdoor
unit and manual for remote controller.

6. OPERATION CHARACTERISTICS
CHARACTERISTICS OF THE COOLING
OPERATION (COOLING OPERATION AND
AUTOMATIC COOLING OPERATION)
•
If the COOLING OPERATION is used when the
indoor temperature is low, frost adheres to 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 or a gentle wind 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.
CHARACTERISTICS OF THE HEATING
OPERATION (HEATING OPERATION AND
AUTOMATIC HEATING OPERATION)
START OF OPERATION
•
It generally takes a longer time for indoor
temperature of the HEATING OPERATION to
reach the set temperature compared to the
COOLING OPERATION.
It is advisable to start operation in advance using
the TIMER OPERATION.
Perform the following operation to prevent
heating capacity decrease and discharge of cool
air.
AT THE START OF OPERATION AND AFTER
THE DEFROST OPERATION
•
A warm air circulating system is employed, and
therefore it takes some time until the entire room
is warmed up after the start of operation.
•
The indoor fan runs to discharge a gentle wind
automatically until the temperature inside the air
conditioner reaches a certain level. At this time,
the remote controller displays "
". Leave it
as it stands and wait for a while.
(The remote controller displays the fan speed that
