6. OPERATION CHARACTERISTICS
■
CHARACTERISTICS OF THE COOLING
OPERATION (COOLING OPERATION AND
AUTOMATIC COOLING OPERATION)
• When operating continuously at downward airflow
direction, air blows in the automatically set direction
for a period of time to prevent condensation on the
horizontal blade. (The remote controller displays the
airflow direction that is set.)
• 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.
■
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 is set.)
• The airflow direction becomes horizontal to prevent a
draft of cool air to the inhabitants. (The remote controller
displays the airflow direction that is set.)
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 air conditioner goes
into the DEFROST OPERATION.
• The indoor unit fan stops and the remote controller
display shows" - ". With the wireless remote
controller, 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 1 O 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.)
58
• During or after the DEFROST OPERATION, white mist
comes out from the air inlet or outlet of the air conditioner.
(Refer to "6." on page 6 3 .)
• 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.)
■
CHARACTERISTICS OF THE PROGRAM
DRY OPERATION
• This operation lowers the humidity without lowering the
indoor temperature. The indoor temperature when the
operation button is pressed will be the set temperature.
At this time, the fan speed and temperature are set
automatically, so the remote controller does not display
the fan speed and set temperature.
To efficiently lower the indoor temperature and humidity,
first use the COOLING OPERATION to lower the indoor
temperature, and then use the PROGRAM DRY
OPERATION. When the indoor temperature is lowered,
airflow from the air conditioner may stop.
• When operating continuously at downward airflow
direction, air blows in the automatically set direction for
a period of time to prevent condensation on the horizontal
blade. (The remote controller displays the airflow
direction that is set.)
• If the PROGRAM DRY OPERATION is used when the
indoor temperature is low, frost forms the heat exchanger
of the indoor unit. In this case, the air conditioner
automatically switches to the DEFROST OPERATION
for a while. The low fan speed or a gentle wind is used to
prevent the discharge of melt water.
AIRFLOW DIRECTION ADJUST
Airflow direction adjustment can be done by remote
controller.
For details about airflow direction adjustment, refer to
operation manual attached to remote controller.
