CHARACTERISTICS OF THE COOLING
OPERATION (COOLING OPERATION AND
AUTOMATIC COOLING OPERATION)
• After continuous operation with the airflow
horizontally or downward, the air conditioner
operates with different airflow direction for a
certain period of time to prevent condensation
build-up on the airflow direction blades.
(The remote controller displays the airflow
direction that is set.)
•
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
system automatically switches to DEFROST
OPERATION for a while.
During DEFROST OPERATION, the low fan
speed is used to prevent the discharge of
meltwater. (The remote controller displays the
fan speed that is set.)
•
When the outside 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.
After operation is stopped
•
The fan operates for about 1 minute to dispel
heat inside the indoor unit.
Perform the following operation to prevent
heating capacity decrease and discharge of
cool air.
AT THE START OF OPERATION AND
AFTER 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 DEFROST OPERATION LAMP on the
light receiving unit indicator lights. Leave it as it
stands and wait for a while.
(The remote controller displays the fan speed
that is set.)
•
The air discharge direction becomes horizontal
to prevent a draft of cool air to the inhabitants.
(The remote controller will display the set
airflow direction.)
DEFROST OPERATION (Frost removal
operation for the outdoor unit)
•
As the frost on the coil of an outdoor unit
increase, heating effect decreases and the
system goes into the DEFROST OPERATION.
•
The warm air stops, and the DEFROST
OPERATION LAMP on the light receiving unit
turn on. (The remote controller displays the fan
speed that is set.)
•
After maximum 10 minutes of the DEFROST
OPERATION, the air conditioner returns to the
HEATING OPERATION.
• The airflow direction becomes horizontal. (The
remote controller displays the airflow direction
that is set.)
•
During or after the DEFROST OPERATION,
white mist comes out from the air inlet or outlet
of the air conditioner.
•
A hissing and “Shuh” sound may be heard
during this particular operation.
Regarding outside air temperature and
heating capacity
•
The heating capacity of the air conditioner
declines as the outside air temperature falls. In
such a case, use the air conditioner in
combination with other heating systems.
(When a combustion appliance is used,
ventilate the room regularly.)
Do not use the combustion appliance where
the air from the air conditioner is blown directly
toward it.
•
When the warm air stays under the ceiling and
your feet are cold, we recommend that you use
a circulator (a fan to circulate the air inside the
room). For details, consult your local dealer.
•
When the indoor temperature exceeds the set
temperature, the indoor unit discharges a
gentle breeze (switches to gentle wind). The
airflow direction becomes horizontal. (The
remote controller displays the fan speed and
airflow direction that are set.)
FAN OPERATION
•
Only the fan inside the indoor unit operates,
and the air in the room is circulated.
