•
If the main power supply is turned off during
operation, operation will restart automatically
after the power turns back on again.
Read the operation manual attached to the
remote controller.
6. OPERATION CHARACTERIS-
TICS
CHARACTERISTICS OF THE COOLING
OPERATION (COOLING OPERATION AND
AUTOMATIC 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.
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.)
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 10 minutes of the DEFROST
OPERATION, the air conditioner returns to the
HEATING OPERATION.
•
During or after the DEFROST OPERATION,
white mist comes out from the air inlet or outlet of
the air conditioner.
(Refer to
IV.
on page 10.)
•
A hissing and “Shuh” sound may be heard during
this particular operation.
Regarding outside air temperature and heat-
ing 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 remote
controller displays the fan speed that is 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.
